Any modders game for 6800U bios?

[LardArse]

Here it is:

http://www.vr-zone.com.sg/Shamino/6800/BACKUP.ROM

Any modders out there willing to do me a favor by looking through it to see if thermal throttling/temperature settings can be adjusted /disabled? Right now it will throttle when GPU is too cold. Also, if voltage can be increased that would be good.
Thx.

[xtremetheme]

What VGPU and Clockspeed does the card have in 2D and in 3D? (Default ones :p: )
And to what VGPU, Speed will the card throttle when too cold?

Can it be its 1.1V in 2D and 1.3V /1.4V in 3D ?

[LardArse]

Its 1.13v without the drivers loaded and 1.43v with drivers loaded, 2d and 3d voltage is the same at 1.43v, and speed is also same at 400/1100. 1.1v and 1.4v should be the correct values.
It will throttle to default clock speed if too cold. If too cold, when the detect optimal frequencies is clicked in coolbits, the car dwill be throttled to 392/ 1.08Ghz.

[xtremetheme]

So you dont have 2D/3D profiles in the detonator like with the old fxes?
Thats sad i liked that feature.

But the 6800 bios is similar to the fx5900, it has different voltage settings for 2D, lowpower3D and 3D included.
Maybe with new drivers we can see that feature again.
And with drivers installed you get more V then before, so it seems possible the driver can tell the card which setting to use.

There is also another voltage setting which isnt activated.
Like with fx5900 you could activate the setting for fx5950 and get VGPU like a fx5950.

So maybe this setting was used in 6800UExtraHigh review samples :p: and gives you e.g. 1.5V instead of 1.4V
But it could also be an intermediate or extra low setting, so your card gets lesser V. It could also do nothing at all. :p:

Im not sure about the clockrates, it seems i see 400/550, 400/600 and 400/400 profiles in there?
Could explain why the core isnt changing in 2D, have you checked if your ram speed is changing?

To the throttling, the only way i know is to adjust the core in the bios manually so it will always adjust to this speed, which makes ocing not so comfortable.
:(

[LardArse]

I'm game for it, setting the o/c settings right at boot up , as long as I can get it to run 1.4v all the time. Can you do that for me? :)

[xtremetheme]

Hehe ok, but first we need to find out what setting means what and if its even used.

In the BACKUPX.rom i changed the three 400er profiles to 390, 380 and 370.
You start a game and see in rivatuner what happens with the core please.

In the BACKUPX2.rom i set the unknow VGPU setting for 3D Mode. Start a game and measure VGPU like you did before.
Its like not possible to kill a GPU with VGPU wrong in BIOS, but if VGPU to low you can get a crash.

I cant guarantee this roms will work, because i dont have a 6800 to test myself.
I dont know if the tools to read out BIOS and compute checksum are ready to handle the 6800. It could be the card doesnt like the BIOS and plays dead, in that case flash the old BIOS back.
So i highly advice you have a PCI card at hand to do this comfortably.

Which tool did you use to read it out?
If not nvlash then try it again with nvflash, some reader dont give the BIOS the correct file size. I had my card play dead because i flashed a wrong sized BIOS.

Maybe you can try to use VGABIOS.exe, havnt tried myself but its supposed to load a BIOS temporaly until next restart. (Only works in DOS i guess)

BTW: What brand is your card?

Good luck hope it all works :toast:

Edt: Removed backupx.rom because it gave failures.
Renamed backupx2.rom to 6800UV.ROM.
(6800U VMod Bios, gives +0.1V in 3D Mode)
http://home.graffiti.net/abiosfile/6800UV.ROM

[LardArse]

Wow, thx man, I'll give these a whirl in a bit.

[LardArse]

Ain't you the genius! Biosbackupx2 gave the same voltage when drivers not loaded but 0.1v more when drivers are loaded. Thx! Havent tried the other bios yet.
That should be the voltage setting for ultra extreme i tihnk.

Haha thats great! :banana:
I got a 6800 BIOS here and it has the same 3D Voltage Setting as your 6800U, and also seems to have the one for the 6800UE stored.
So that can be good news for the upcoming 6800 users to get 6800U speeds.

[Tom Holck]

very interesting reading xtremetheme:toast:

can you make a rom-file with 600/650 ?

My Gainward goes 400/600 default with 1.6 3ddr-ram.

If I load your backupx2.rom I'll get 0.1Volt but what about the core and ram speed?

You mean 600 core and 650 ram?
Hehe then be sure you have good cooling. :p:
I could but i dont know which speeds to use until someone tested BACKUPX.rom.

Do you still have your old bios?
I would more likley change the values there, because cross flashing bioses from other cards on FX5900s resulted in not working tv-outs.

Yes, 600core 650 ram:D for a start.
I have one of the worlds best dual cascades.
not working tv-out is OK!

If not LardArse or someone else test the BACKUPX.rom I will do it, but it will be in next week :(

It will be great: 3DMark03 175xx "bios supplied by xtremetheme!"

[LardArse]

xtremetheme, backupx made my PC behave weird, Riva tuner cannot detect the clock speeds and if I click detect now, the whole screen will go bonkers. Trying to access the 6800ultra tab in the display properties results in a crash. Perhaps we might need to change one at a time?
Are there any temperature settings in there? Anything lower than 25C core is detected as red-hot/danger and so very susceptible to throttling.

Hmm i ll look into it. What is the throttling temperature stated in your temperature tab?

[LardArse]

There isn't really a throttling temp to be seen there, just what I said, 25C and upwards, it shows it to be in the very safe zone, but drop 1 C to 24c and it immediately jumps to red hot level/danger zone.
There's the maximum threshold of 125C in the thermal settings tab which cannot be changed.

http://www.vr-zone.com/Shamino/6800/thermally1.JPG

[xtremetheme]

Thx, i think i found the failure with the clock speeds.
http://home.graffiti.net/abiosfile/BACKUPX3.ROM

Try this if you get 390/540.

[xtremetheme]

Good news from home, i was able to locate and change the core slowdown value on my FX5900. :)

I can also change this on the 6800U it seems.
Its just a theory, maybe the card has a operating range of 100° and if it goes out of bounds on either side it will think "WTF??" and slowdown.

I changed the max threshold on this BIOS to 100°, if the theory is right you will able to go down to 0° before card slows.

http://home.graffiti.net/abiosfile/6800UVTHRTEST.ROM

If this all works i can set the slowdown to 0°, meaning the card would only work from -100° to 0° which is truly extreme :D

Well, then we must raise the volt a little, so the temp don't drop below 100 C:D

Make that bios, I'll try it in a few days:toast:

The temp was -120 C on the ATI x800 default volt.

[Symphysodon]

Hello there,

I will buy a 6800U soon (there isn't any card available in Germany yet :-/) and will cool it with a 230W peltier, so i hope to reach sub zero temperatures around -25°C Idle...

LardArse, i knew the phenomenon with the abnormal behavior from my fx 5950 yet - it also shows a totally red diagram if the GPU is too cold, but it did never set the clocks back to default - I was able to overclock the card via PowerStrip v3.46 even under 25°C.

Please try if you are able to overclock after cooling it under 25°C with PowerStrip, this would be very interesing for me... and if it works, ur problem with the throtteling behavoir wouldn't exist anymore :smileysex

By the way, is the true temperature shown if you cool it down lower than 25°C?

xtremetheme: If no way helps to make the card working correctly with lower temps than 25°C, it would be nice if you could build me a BIOS with a range from -40°C to 60°C and +0,1 V Vcore please - actually i'm not able to use two BIOSs the same time :D

Thanks for help..., regards from Germany,
Symph

[LardArse]

Coolness! I'll try the core slowdown bios in a bit! Thx for all these xtremetheme! :)

[LardArse]

Xtremetheme, it does set the core slowdown to 100C but it doesn't change the cold throttling/ 24C and below recognized as red-hot.. Should be something coded in the drivers.
I'll try the 390 bios then, if need be then we'll have to throttle the card to 600 then :)

[LardArse]

Yes, now the card throttles to 390 with that bios. But memory throttles to 1080 or 540 mhz. There are artifacts on screen after the throttle though. Any memory throttle values there?
I take it that this is the throttle speed and not the boot up speed?

[xtremetheme]

Hmm yeah could be it can be overrided by the drivers, i vaguely remember some one posting his slow down temperature on FX5900 changed when he installed a new driver version.
But if the max slowdown is stored in BIOS the min is maybe also there.

This throttling on too cold, did this also happen with the FX5800/5900?

Yes it should go to 390/540, thats what i wrote, to also test if the memory value is right. Damn i have no idea why there should be artifacts.



Originally posted by LardArse

This speed should be the new default speed for the card now, and the 6800
falls back to its default speed when it throttles from my understanding of your reports.

Just disable any ocing and see if the new default speed is 390/540 from start on.

Or is there any situation when the card speed goes to 400/550 again?

[LardArse]

Heck it, I can live with the artifacts for now!
Can you please write this bios? :-

- The Ultra EE (special voltage) setting if possible right at boot up? Anyway to replace the 1.1v boot up value with the 1.4v or 1.5v of the ultar EE?
- A default/throttle speed of 600/1265

To be safe, perhaps you can write the bios for the 1.5v bootup with 390/540 first if possible?
Thx man, we're getting there
;)

That shouldnt be a problem :)

This BIOS should give 1.5V in every case, and speed 390/540.

Bad news, the bios does not load 1.5v at boot up. I also can't load into windows with this bios until GPU warms and unthrottles. How about the other 400s you see as well? Can you change all these to 410/1120 to try instead?

Hmm bad.
This Bios is default @390 and the others at 410.
I set the bootup to 1.4V, maybe that works.

[LardArse]

Hi xtremetheme, the card has no problems booting up at 600/1265 with 1.38v.
However, can you write me a bios that has the default voltages :ie- 1.1v/1.4v but with 590/1240?
And another bios with the 1.5v and 590/1240?

[Stylist]

Hi,

I have a NV6800GT. Do you see any chance to flash to 6800Ultra?

At least could you modify my current BIOS to provide +0.1V (GPU) in 3D?

And which tool (nvflash.exe -version?) to use and which parameters (nvflash -f name.rom ?) to force the flash?

I attached a backup of my BIOS (just rename to .rom).

Thanks in advance!

Regards

Stylist

[EmineM]

im also looking for a modded 6800 bios :) non gt and non Ultra

[xtremetheme]

I dont know if you can flash 6800GT -> 6800U.
But it seems the GTs also have the +0.1V setting.
http://home.graffiti.net/abiosfile/nv6800gtV.rom
:)

I use nvflash 4.41 but i dont have a 6800 so i dont know if that works.
If you flash your own BIOS you shouldnt have to force anything.

Remember to have a backup plan e.g. PCI card.

Thanks!

But it seems that it didn't work.
I got display corruption after start up (Windows) and no improvement in overclocking at all.

EDIT:

Flashed it again and no display corruption any more, thanks.
But there is no recognisable improvement at all.

Could you check the settings once again?

What did you exactly modify? VCore for the GPU +0.1V?

Thanks in advance,

Stylist

[JacobHansen]

Is there a bios that has the default voltage of 1.5/6v ?

Our card is acting very weird, with a mach II mounted on it.

Displaying 10 deg. in the driver with and without overclock..

The Card is a Leadtek A400 GeForce 6800 Ultra..

The ram on the card does around 1230 with out any voltmods, and the gpu runs at 460~ ..

Yeah i set the option for +0.1V in 3D, but if it doesnt work maybe the GT has another PCB or such that is not designed for providing the 1.5V setting?
Sorry dont know :(

[xtremetheme]

Pplz how about your mod bios yourself, its not very hard.
Look here:
http://img6.exs.cx/img6/8830/oc6800.gif

You do a search for 10020300 and after that you see your voltage settings.
The speed is in the area a bit above.
Remember you must reverse the hex values.
After you edited, use nvchk.exe to write a new checksum and you can flash.

[JacobHansen]

hey xtremetheme, thank you very much for the post about the bios.
Could you please help us with the values for for instance 540Mhz core and 1200Mhz mem?

Btw. what program are you using for editing the bios?

[Stylist]

Thanks!

Are you sure that "03" stands for 1.5V? How did you get those values? - Ultra BIOS?

The results let me believe that it could be lowered instead of beeing increased :confused: .

BTW: He uses probably ultraedit or an similar HEX editor.

Thanks in advance!

BTW: Your location is Germany, do you speak german?

But how to find and identify the values for GPU/RAM settings?

And how to change the 2D and especially 2D/3D settings and where to find?

I need the following:

Voltages:

2D=1.1V
2D/3D=1.4V
3D=1.5V

-> this means: 0082 018C 0300 right?

Frequencies:

2D=350/500
2D/3D=410/550
3D=425/560

-> where to find and how to identify :confused: ?

Thanks in advance!

[xtremetheme]

I use a simple Hexeditor, HexWorkshop in my case.
036E0082028C01
You see the 03 at the very beginning says there are 00-03 possible options.
Was the same with the 5900 BIOS which had up to 07 setting.
Shamino measured the 03 setting with 1.5V...

[Stylist]

What would be +0.2V = 1.6V?

No, I guess it works.

automatic scan for highest value with coolbit:

Before applying moded BIOS: 399/1080
After applying moded BIOS: 411/1200

So where did you get the values, what was for 1.6V?

Edit : Finaly I found it :)

[LardArse]

Great stuff xtremetheme, this will help a lot of 6800 users, especially the GTs :thumbsup:

[bmg]

Could someone post links to the necessary tools needed to read/flash and also nvchk.exe? xtremetheme, would it be possible to email them to me at bmg2@cableone.net?

Got them. Thanks.

[drcrawn]

Been following what you guys have cooked up, simply amazing! Way to go. I noticed that the original 6800Ultra being used is a WInfast 400. I have a 6800ultra with the reference cooler. I can hit 466/1.23 with air, so I know this card has some nice potential. The Winfast HSF is all copper right? If you would be willing to part with it...maybe we could work something out.
Anyway, I hope that wasn't inappropriate.
Do you guys have a normal Ultra Extreme BIOS that I could flash my Ultra with? Thanks.

I think it means the card or the driver doesnt use 2D/3D Profiles.
You have a 6800?

Do you find 5E01 in near of a F401 in your BIOS?

[rycky]

My card is a 6800ultra from MSI but with reference design and even liveupdate doesn't recognise it like an MSI...
If I use nvflash 4.41 I can't flash because it says to me that there is no nvidia adapter in the system (too old for the kind of eeprom of the 6800?) but that's work's fine with 4.46 if PCI vendor and PCI ID are the same... I've more recent bios but from gainward and point of view and I can't flash it using 4.46 (no options to ignore PCI ID and 4.41 with this option doesn't works :( )
Could you tell me where PCI vendor and PCI device are identified in order to mod the bios and allows me to flash with 4.46?
thks

PS: don't find 5E01 near F401

[rycky]

I found on the net nvflash 4.42 and that's works with the command -p -u y to ignore different vendor and PCI device! I used bios 5.40.02.10.14 (6800uv3.rom in the zip file) from Point of view and modded it in order to allows +0,1v in 3d mode. Amazing the defaut clock for the GPU with this bios is 425mhz (I don't change anything...) The TV out works fine although the brand is different, very good!
http://rycky11.free.fr/Forum_Hardware/Bios6800u2.zip
I'll try with Gainward bios even more recent as soon I've it. In the zip file the nvflash version version is 4.42.

I would need the 6800 Ultra BIOS.

[rycky]

For the ultra ;)

[bmg]

I've got the new 6800 Ultra bios, version 5.40.02.10.13. It's dated 06/15/04. I've been playing around with it, and it's as easy to mod the frequencies and voltage as the old bios. I've also got the new nvflash version 5.08. Can anyone host these? I'd be happy to email them to whoever would like them until they get hosted by someone.

On a related note, I've got a question about the core voltage measuring point from LardArse's vr-zone article. When I measure the voltage I just see the 3D value all the time, rather than the lower value for 2D. Is this normal? I expected to see 1.1V for 2D changing to 1.4 or 1.5V for 3D. Here's LardArse's picture:

Update, never mind on the voltage, I see from LardArse's early posts in this thread that he sees the same voltage whenever the drivers are loaded. I'll have to check the voltage when I'm not in the OS.

I've also got the new nvflash version 5.08. Can anyone host these? I'd be happy to email them to whoever would like them until they get hosted by someone.

On a related note, I've got a question about the core voltage measuring point from LardArse's vr-zone article. When I measure the voltage I just see the 3D value all the time, rather than the lower value for 2D. Is this normal? I expected to see 1.1V for 2D changing to 1.4 or 1.5V for 3D. Here's LardArse's picture:

Update, never mind on the voltage, I see from LardArse's early posts in this thread that he sees the same voltage whenever the drivers are loaded. I'll have to check the voltage when I'm not in the OS.

I wonder why 5.40.02.10.13 (06/15/04) is most recent than 5.40.02.10.14 (06/01/04) Could you send this bios by mail please. (You've got a PM );)
I'm disappointed because I can't find the offset that set the 3d frequencie. With bios 5.40.02.10.14, 2D frequencie is 400mhz so the value 9001 is the same at the same place but in 3D the frequencie is 425 so I think I must find 6110 (425 is 1061 in hexa) and I don't find it :(

[bmg]

I've sent a set of files to Stylist and rycky. I think one of them will host the files so they can be downloaded. I've included the addresses of the locations of the voltage and frequency values that can be changed.

The value you want is A901->01A9=425 decimal.

Check your email for the files. I've included all the address offsets.

I jope one of them get's it done pretty soon, I'm sitting here and trying to flash this damn card.
First time I flashed a bios which doesn't boot...

The Ultra Bios doesn't work on the 6800GT.
Anyone knows how to change the BIOS values to fix the problem:

"...ID mismatch..."

You can use nflash 4.42 with -p -u parameters in order to ignore this message. Be carreful you should have a PCI card in security if the ultra bios isn't ready for gt. I think it is but be carreful.

Where to get 4.42?
With version 4.46 the parameters doesn't work.

Thank in advance,

[drcrawn]

Since you guys have looked at these bios' codes, r there major differences? Worth flashing with newer? Does the UltraExtreme bios set the core temp thresh at 130c or does it remain at 125c like the Ultra? GT= 120c. Thanks guys. By the way can someone explain "light pencil job" a little differently, or add perspective for noob? Much obliged.

Would anybody mail me a moddet 6800GT Bios?

1.5 Volt @ 3D mode

I wasn't able to do it myself. :(

Make a backup of your bios file in order to mod it. When it's done PM me and I give you my mail to send the file.

[Crozet]

Hi,
i was try to mod my PNY 6800 GT Bios the way you describe here but unfortunately it didnt worked.I was trying to change the voltage for 3d.On my card it is 1.3V that i measured on the back of it.I changed the value according the picture posted here but the voltage stayed the same even i put the value for 1.5v.I used the Nvidia Bios Editor from Ray Adams to open the bios and changed with the integrated Hex-Editor the value.Any clue why it didnt worked?
thx

edit: maybe if someone can mod it for me i would be very thankful.Please do 1.4V for 3D since the default by my GT is 1.3V and further as 1.4 i dont wont to go! thx!
here the original PNY Verto 6800GT Biosfile: PNYGT_BIOS (http://home.arcor.de/crozet/files/pny_gt.rom)

[Goldlocke]

crozet, use this Ultra bios.
It goes to 425 in 3D / 400 2D.
VGPU @ 1.42V.

I'm using it too. :)
remove txt first.

Sweet im gonna flash mine with that. Now i just need to figure out how to backup my BIOS...

xtremetheme, thx so much and everyone else whos helping out :D

[Goldlocke]

save your old bios with the - b flag.

[xxORBxx]

lol right after im done flashing. I figured it out though. Is it normal that i have to reinstall the drivers? :confused:

This bios didnt work well for me at all :(

Crazy things in 03 and eventually froze in mothernature. Think someone can edit this bios to 400/1100 1.42 vcore?

[xxORBxx]

I figured out how to edit properly.

Anyone who wants it here it is.

PNY 6800 GT
400/1100 and 1.4 vcore.

[ctgilles]

Does the GT -> Ultra flash just works?
I have a BFG 6800 GT 'OC' lying somewhere, I could try, but I don't want to kill the card obviously ;)

Please advice :)

[Goldlocke]

Ctgilles, of course the flash works. I have yet tried nearly every bios around the web on my GT. :)

Didnt really work for me too well. had some crazy shadows and ghosting. Just Get your bios off the card and edit it to how youd like.

[Fire_Two]

hey guys,

i have a XFX 6800Ultra

stock clocks being 425 core and 1200 mem,

just wanted to know if any 1 has that bios with the upped (1.5) vgpu?

my bios date (sticker on the back says)

5.40.02.10.14

card also says xfx, v1.2, 07/04 not sure what that means?!

[xxORBxx]

My GT wouldnt let me go to 1.5v for some reason :confused:

My advice is, edit the bios yourself and find out if it works.

[yuri]

can someone explain what needs to be done, all i get is load error in dos while trying to flash with orbs bios

That bios is newer than mine. Could you email a copy of it to me?

The 07/04 is probably the manufacturing date, or the date of the version 1.2 revision.

Yuri try
nvflash.exe -f (biosname.rom) -p -u -2

If will flash for sure that way. Or just change yours for motr vcore.

[yuri]

i changed the name to 6800ultra.rom


and when i type

nvflash.exe -f 6800ultra.rom

it say load error: no dpmi Get csdpmi*b.zip

Alright my bad, Just put all the files in this rar on a floppy, i dont really know whihc you need. It was posted above somwhere.

For some reason i can backup my bios but i cant load orbs bios (we have the same cards)

i have edited my bios with the higher voltage but i dont think i using NVCHK right, dos window pops up and thats it :(

You have to bring up a Command Prompt (Programs/Accessories/Command Prompt). Then CD to wherever your new bios is and then run "nvchk bios_name.rom". You can't run nvchk by just double clicking on it.

whats ur email BMG?

0707 = 125c shutdown so 25c-125c is the zone without problems,

I have a 80w pelt and at 9c everything is screwy when i try to overclock because of the 25c problem.

what is the value needed for say 0c-100c ?


TIA Yuri

[xxORBxx]

I thought the value for 125c is 7D7D like in the pic above. So with the hex converter im using

125=7D
and
100=64

You card is a GT and they core shutdown or whatever its call is 120 which is 78.

So if you can find a 7878 somewhere...and replace it with a 6464, that might work...but im no expert. I would try that and see how it goes. The thing i dont understand is why there is two values. I would think it would just be 7D in the pic, but its acutally 7D7D. Im not sure if that double value pattern thing works, but its worth a try.

[drcrawn]

Thanks so much for the awesome volt mod bios extremetheme!!! You gave me a boost in overclocking stability!

http://service.futuremark.com/compare?2k3=2798582

[Kane]

Is there any difference in the RAM voltage between the Ultra and GT bios? I just Ordered a Gainward GT card. It has 1.6ns memory. Will I get more out of this memory by using a Ultra Bios? I know the Ultra bios has higher voltage on the Core, so I expect a higher overclock on that using the Ultra Bios, but will I get a higher RAM overclock?

Regard

Jim

[drcrawn]

after flashing with ExtremeTheme's BIOS, I still show 5.40.02.02 although its clear I have more overclock in fact 492/1.26 is stable and still going... should my driver show a different BIOS version?

[xxORBxx]

Its prolly the same bios you used before, just with his mods.

[ant1]

Anyone having a point of view GT bios with 1.5v by any chance?

[drcrawn]

post number nine is the modded GT bios i believe

[nigelyuen]

can someone mod the bios for me
its a winfast 6800nu
thanks

[yuri]

Ok here is what im looking at,, i cant seem to fine the thermal values :(

can someone show me the 7D7D or gt value and what it needs to be.. thanks

btw i have done the volyage increase, that was easy.

http://24.158.154.102/images/hex.jpg

[xxORBxx]

I tried to find it last night for like 30 minutes and still couldnt. Someone show us what to do plz :confused:

[nigelyuen]

i couldnt find anything in 6800nu bios

[xtremetheme]

Well the 7D7D was for 125° core slowdown, maybe your cards have different.
Look in your forceware temp setting there is your max temp written.

[nigelyuen]

my is 135c
anyone can enable the last 4 pipeline?
iam willing to test it

[JimLad]

Lo chaps,

I have an XFX GT, and the core refuses to do over 380 in 3d mark '03 :slapass:

I would like to try upping the core voltage from 1.3V to 1.4V and see if that solves the problem. Ideally I would like to hit 400/1100. Cooling is default (lapped the heatsink and used silicon paste on mem. but thats its). Can I upload the bios on here then someone mod's it for 1.4V? If so how do I backup my current bios? I've not messed with gpu's bios' before so I'm not familiar with the utilities used :shrug:

On the GTs the core slowdown is 120° so wouldnt that make the value 7878 or something like that? Ive searched the bios for 7878 but cannot find it. I also looked in the area around the clocks and voltages but it a 78 was nowhere to be seen. :confused:

[yuri]

120c is the shutdown temp for me and orb.

0c-100c would be sweet. but looking in hex i can find anything that looks like what yours show.

[YCH]

Dudes I got back my BFG 6800 Ultra and I'm trying to look for the offsets to modify the VGPU but I can't find it!

The offsets are quite different from the pic extremetheme showed!

So how do I look for the values to modify?

[xxORBxx]

convert your clocks to hex, then reverse the 2 number like in the pic and search.

400 in hex is 0190 so flip the pairs and you get 9001 which is how it will appear in teh bios.

Eh, nvm I was an idiot. I found the offsets to change.

Seems to be working, and helps my Ultra stay stable at 470

Hi, the theory that the slowdown has a 100° range was false, as you can read by shaminos answer in the early pages.

If you change the slowdown from 120 to 100, all you would get is that your card slows down at 100 instead of 120.
Which would be counter productive for ocing. Its doesnt change the slow down at low temperature.

The BIOS is the right one for PNY 6800 GT, but I'm afraid you will have to run nvcheck against it in order to recalculate the checksum, otherwise your videocard will not work any longer :)
Looks like all GTs have problems over 380Mhz (like mine was), after this bios update I'm running PNY 6800GT@Ultra with absolutely no artefact.
Good work!

Yeah sorry about that, didnt run nvchk before posting.

[GravY]

if anyone can adjust the voltage on this would appreciate it..

my card can do 440/1150 right now.. I messed with the Ultra bios from Leadtek and was able to do 440/2000.. but reverted back because temps were 5-10c load higher with the ultra bios compared to the GT @ same clocks..

Thanks..

Great info!

GravY
BFG6800GT

[xxORBxx]

Your temps were higher because you were using more voltage...so upping the voltage on your current bios, is gonna have the exect same results.

[GravY]

I gotcha on that, I should have composed that post alittle better, was in a rush..

can the voltage just to the ram be upped, I could hit 440 before the Ultra flash and after so I don't think the extra voltage is going to help me there, but the ram I was at 2ghz and honestly didn't test past that, so the extra voltage to the ram would benifit me some..

[xxORBxx]

You cant change the ram voltage without a vmod i think.

[GravY]

ok, thanks then, I'll stick with my GT the way it is..

yuri can u help me get my fx-53(940) stable at 2.7ghz? No matter what voltage I give it, the damn thing won't accept a 13.5 multiplier. 2.6 is fine, even 2625mhz is fine. 2703 is no go even at 1.77v. I might need better cooling for 2.7, but I dunno, my temperatures seemed fine, never above 50c under heavy load. whadya think? Thanks.

my 6800ultra mem with the extreme bios does 1.27 no problem looks like. the core, 499 is as high as coolbits has allowed me to go. makes for some nice benchmarks numbers

[13artjan]

is it possible to activate all 16 pipelines in an 6800nu using bios upgrade?

if anyone gives me a 6800GT bios with speeds set to: core 325 and memory 700 (350) i can try if that activates them

[13artjan]

i tried ur 6800 ultra @ non-ultra speeds bios and it works
dont know how to see how many pipelines are active, so cant say that

however there is no noticable difference in performance and even worse.... in 3dmark it lowers the score (about 700 points in 2k1 SE and about 400 points in 2k3)
the load temp stays about the same as with my point of view non ultra bios, about 68 degrees celsius
idle temp however is about 4 degrees celsius higher now, from 61 to 65 degress celsius

overclocking seems to be the same to, still about 410/825

btw if u need/want my point of view 6800NU bios, ask :)

Hi all.

Just a question for anyone who may know.

I flashed my S-Media 6800U from it's original bios version of 5.40.02.03.00 to a Nvidia reference rev2 bios 5.40.02.10.15 basically because the original bios the card came with had fast writes dissabled and the nvidia rev2 bios had it enabled. The flash was successful with everything stable and fast writes enabled.

I used commands -2 -p -u -f ####.ROM - "####" being the file name.

However, and here in my question lies. During the bios flash there was a warning (I can't remember what it said exactly) saying something to the effect of unable to copy IEEE 1394 GUID not enough space.........don't quote me on that but it was something to that effect refering specifically to the IEEE 1394 GUID, the flash process continued and then stated flash successful.

Now what does that warning message imply????

Has some feature been left of the card after the flash?? I'm just a little worried that I may have lost some feature of the card??

[13artjan]

it is recognized as an Leadtech Research GeForce 6800 Ultra [NV40.0].

i dont have a digital camera (or a normal one for that mather) so cant help u with the pic tho :(

[13artjan]

btw. my PSU didnt like the 1.4V

1st i had a low quality 350watt that freezed during gameplay and 3dmarking, then i switched to a high quality 300watt which worked perfectly. until the 1.4V mod... after 2 days of running it freezed too, also after putting the non-ultra bios back.

so had to go buy another PSU :S
have a 400watt xtra silent 1 now :)

[ant1]

Ok I just flashed my card with xtremethemes bios but ended up with no better oc. Has anyone a working 1.5v Bios for the GT That definitely works?

[drcrawn]

there is debate about what the voltage difference if any there is between a Ultra and GT. Can someone please shed some light on this for me. I say they are both set at 1.43, but someone is telling me that Ultra bios is +.1v over the GT bios. this sounds wrong to me. Thanks...

[Juice]

Hi, does anyone have or done the bios fix for the 25c problem on the 6800ultra? I'm kinda uselss with hex editors. How did shamino overcome that 25c problem?

[ant1]

flashed my gt to ultra now. it´s stable at 450 now but no single mhz beyond. scores aren´t as good as before but that might be driver related.

Flashed my PNY6800GT with the bios provided by you (ran nvcheck first ). Could not do 400/1100 before. Now I am at 425/1150. Temps about 5-6 degrees higher but not too bad overall. All stable :)

How high do you guys get with watercooling and +0,1 bios? Im intrested in both GT and Ultra OC´s

[esoteradactyl]

i hope the throttling issue can be resolved. i just modded up my mcw50-t to fit on the ultra. someday i wish to use it :slobber:

ok: i have an ultra: check these numbers out:

before watercooling or flashing: 467/1.23 highest stable overclock on air and stock vcore.

after watercooling but before flashing: 478/1.26 highest

after watercooling after flashing with Xtremethemes mod bios(+.1v): 499/1.28 highest, normal 99% accepted 496/1.28, coolbits will not accept 500core no matter what...

so, you can see that these cards are greatly volt starved if you can provide watercooling. My core temps never broke 60c with 90f ambiant room temps and a case temp of 40c plus (yuck). Normal room temps like 73f, the core idles at about 33c when warmed up.

i use the mcw-50 block with non-chilled water and the absolute lowest core temp I ever saw was 27c, and that was right at startup with a 66f ambiant room temp. The throttleing begins at 25c, so you dont have to worry about it with normal water cooling. The core will quickly warm to at least 29c is most cases unless your room temps are really chilly, like mid 60s.

is that with a 80w or 172w pelt?

whoa, sorry didnt clarify myself, that is with NO pelt. if u go that route, you will run into the throttling I imagine....

Hi! I also have a PNY 6800GT, that I'm considering putting a modded bios into. Presently mine is completely stable at 423/1000 with idle temps of 62/45 and load temps running rthdribl of 85/61, all I've done is redo the stock heatsinks with artic silver 5.

Do you have any other comments or advice about doing this bios flash, or any problems with your card? What temps do you idle/load at? What size powersupply is in your machine?

rms

[rms]

Success!!

I used the PNYGT14V.ROM that Crozet posted on the last page of the thread. Looking at in the editor, it puts 2D/3D at 1.4v (1.3v stock) and 3D at 1.5v (1.4v stock). It has the same bios number as my PNY 6800GT 5.40.02.15.01 and flashed right in with no issues!

I've been running rthdribl at 434/1140 in a window (2D/3D) for long periods, and am about to try Doom3 at these settings.

IT RUNS MUCH HOTTER, peaking at 93/65 in rthdribl vs 85/61 before at slightly lower clocks. I won't be surprised if it hits 100C in Doom3, and this is after AS5'ing all the heatsinks. Improved heatsinks can't come fast enough for these cards.

Anyway, I'm delighted with the results

Hmm we have problems with the availibility of 6800 cards here in Europe. Have been waiting 2 weeks for my 6800GT now and its likly to be 2 more :(

At least my Dangerden 6800 card is on its way. Can´t wait to test it with My card and a +0,1 bios :D

[Shadow of kaos]

i got my 6800 ultra yesterday and i live in wales in the uk! really sruprised to recieve it this early! i had been waiting ages for x800 xt until i changed my order. This card is awesome! my clocks come as 425 core - 1.2ghz memory ( XFX 6800U ) the problem is, it wont really overclock at all for some reason.. if i could get more out of it it would be even greater.

as it stands i am gettin 12k 3dmark 2003 marks with it right now, and i dont think thats all that bad considering i have an athlon xp mobile oc'ed to 2.5ghz.

anyone doing voltage & cooling mods for this card @ a decent price? if anyone here is, let me know.

hey guys, fellow 6800u users. I know some of us have been working on our cards for a while eeking out the performance...
I need some advice, I can clock my ultra to just over 500 core and 1.30 mem, stable on water with xtreme's backupx2 bios.
The temperatures are fine. So my next step would seem to be more volts.
Man this thread has come a long way since those first posts...can someone who vmodded give us a quick update on the correct procedure as the original picture was incorrect right?
Thanks i appreciate it, y'all.

You don't say what motherboard, but there are a couple things to try. First is raise the AGP voltage in bios one or two notches, this often helps stability.

Secondly you have a highly overclocked cpu, raise both your chipset voltage to the maximum setting and Vdimm as well, and consider a voltage mod to raise Vdd to the 1.9v range. Also adjust memory timings for stability, like 10-3-3-2.0 to around 12-3-3-2.0 at 220-230fsb (assuming CAS2 pc3500).

*Also*, realize not all games will run at the same overclock. Specifically for me Far Cry simply *will not run* at high 6800GT clocks, I have to backoff to 392/990, while doom3 is happy at 430/1040 (after the modded bios).

welcome to XS chinabox :toast:

try to test your 6800U at default speed on ram and CPU. Then you can see if it's the Grafx that make the crash.

A newer bios might be better, but I don't think thats the problem.

[Mental]

I just installed my new watercooling system. With an AquaComputer waterblock for my POV 6800GT card. Now there is a problem, my CPU core temperature is 26C. I know this because I changed graphicscards and started the computer. I don't know the temperature of my GT though I think it is a bit below the CPU and I therefore think it is below 25C.

The problem is, with my waterblock mounted on the card, the system woun't start. There is no picture on the display. I tried to connect the standard fan while the waterblock was mounted to check if the card registered the missing fan and wouldn't start. The card sadly did not start.

I know the card is not broken, so I think the problem is because of a too low core-temperature. Does anyone else have the same problem? Is there a solution for this?

If you know the values to change in the BIOS, xtremetheme, I would be really greatful for an answer.

Tnx!

Hi'ya The Runner

don't think the cooling would be up to it......

but i have a BFG6800u'oc with a water cooling bios stock clocks are 470/1100 i modded it to 470/1200,,'dangerden nv68 water block',,,,,i also have bfg6800u'oc bios rev1, 2 and 3, and could set the clocks to what ever you wanted, but if you did you would have to work out the highest stable clock speeds first.......and if you'd want the 1.5 3dvolts, it does put the loaded temp up a bit.......

I don't know for thrtl. voltage? and why can't we go over 1.5V? Is it not safe?

[jeffstet]

hi,
I'm new to xtreme forum and just discovered this thread. I have a golden sample 2600 from gainward and i was willing to know which was the best bios for it and if it was possible to edit the bios to raise the voltage. I have downloaded a few bios but while editing through omniedit i had crazy core and memory freq so i didn't flash them. I'm stuck at 430/1200 and i hope that raising the voltage would help to O/c the card a bit more.
I also heard that there was a problem with timings too low in the official bios (the 15.06) and that it was the reason of ingame bleu screens and freezing.
Any one could tell me what bios to take or even better link me a "safe" bios with 1.5v or tell how i could proceed?
Thanks all

Is there any chance I can flash my eVGA 6800U to 6800EE? I can't get the EE bios through card registraition :S Can somebody send me a copy of the EE bios?

[Paxi]

can i flash the evga ultra extreme bios to my 6800u from POV??

[MrBean]

Hello Everyone,
Ok, a small favor if I may: I can't seem to find any Ultra-extreme Bios over at Gainward's site, and wonder if anyone with this card can save me his bios to a file and email it to me...or PM whichever is best.....

It must be the Gainward U-E bios, please.....

All modders out there should take note of my experience: I found that the offsets in the Gainward Ultra differs greatly from for example the eVGA and some others modified here.

If any of you need a Gainward Ultra Bios which I have modified to 425gpu/1200mem and active 1.50Vgpu softmod, I will gladly provide it.

Other than that, I have recorded the offsets and changes in a word document, but can save that to notepad/wordpad format, and post it here should there be any interest.

edit:Just for the record: on standard room temp water I managed 479 on the gpu with default bios, after the mod I can do 489/490. On 3dMark03 I managed a 15579 score with 3.4EE running at 4.16gig, and card at 479gpu/1365mem.

After the mod, I can do 15580, a 1 point difference, with cpu at only 3.90g, and card at 490gpu/1365mem. So, well worth the effort in terms of cpu benching stability :)

Br,
MrBean.

[MarilynMX]

I found eVGA's UE bios but it said it didn't match my current video adaptor. So I can't flash my 6800U to UE right?

[MrBean]

Hi MarilynMX,
Ok, I am not professing to know to much about current adapters, point is that is both are based on the same reference design, which I am sure it is, then there is no reason other than quality of component why it would not accept the flash......of course you will have to force the first flash from 6800U to UE due to the fact that it will tell you that the hardware is not recognized.....

I am going to flash my 6800U Gainward with the Gainward CoolFX GS Bios tonight (South African Time - GMT+2), I already confirmed bench/gaming stability at 480/1200, so this card can safely handle the 450/460 spees of the GS-series......

I will keep you posted of my prowess, and the flags I used......you do the same :)

Br,
MrBean.

[MarilynMX]

nvm I just did it with -5 -6 parameters since -p -u didn't work for me
new bios allows my card run default 450/1200 in 3D mode :D

[MarilynMX]

Guess I'll have to get a new HSF or WC system for this card, it runs HOT in benches :(
Thank you MrBean for keeping me posted :) I'll share my experience with anyone who needs help flashing their Ultra's

[MrBean]

Thats good news, MarilynMX, so U-E speeds is then by default 450/1200...well, I anyway edited my bios last night (hex-editor) and flashed it to the 450/1200 default speeds, I also upped the vgpu to setting 03 for 1.5vgpu, but it is not needed, only for benching past 479, as my card is really very stable and game-playable at anything up to 475/1250 with std bios voltages!

These Gainwards are nice cards, I have 2, one in my Wife's gaming rig, the other in my Benching setup, and both get at least 470/1250 with Cool-Matic waterblocks.

So I can highly recommend this watercooling solution, or you can get the Dangerden one.....

Will let you know what the CoolFX bios does to my card.....I hope it will unlock the Expert settings in Gainward's Expert Tool......and let the clockspeed go past the current 470 limit :( I am using either Coolbits or Rivatuner to get past the limitation, but I think the Expert Tool might be better, as it doesn't test your settings before it sets them...lol...

Speak to you later.

[MrBean]

Hello Guys,
Ok, some feedback: I flashed my Gainward 6800U with the CoolFX Bios, and it worked ok....well, no problems with the flash, etc, booted fine, could even do benchmarks....

One thing I noted though, is some slight artifacting around 475gpu speed, in 3dMark03, where the Trolls are playing their chess game....I see some pinpoint lights on the 4 chess pieces.....which I don't see, even at 489gpu speeds with my standard 6800U bios.

I cannot overclock as high either with the Coolfx bios, and when I do optimized calculation to determine max overclock, it gives around 466/1230, whereas my std Bios gives 477/1260 or so.

I compared the 2 bios'es in hexeditor, and besides the standard ID bytes, there are a few other areas where there are differences, which I think may be the memory timings....

So yeah, besides the fact that it unlocked the CoolFX button in the ExpertTool control panel, which allows quick setting of speeds to Enhanced CoolFX speeds at 450/1200, it didn't do much for me....which was expected. Even the vgpu is set to 1.4 in the bios, so I decided to edit my std 6800U bios and adjusted the vgpu to 1.5.

So my overclocks are around 489/1365 with the new bios, same on the memory, but 10mHz up on the gpu. Will play some more and keep you guys posted.

Br,
MrBean.

[Skip]

i noticed that there are a couple bioses that have a core slowdown temp available for adjusting using Nibitor and then some the core slowdown temp is disabled completely, along with the timings. is this possibly something that can answer the thermal throttling?

[humeyboy]

OK peeps, i have read some of you having probs with overclocking after so many % in coolbits, well coolbits only lets you go so many % over default clock then you need add new reg entry called BART, as most know coolbits aint a proggy or app, its simply a new reg entry to unhide already there nvidia settings, you can type it in manually.

http://oc3dmark.octeams.com/tip02b.html

All i want to know is, i got a great Chaintech 6800 Ultra @ 425/1100 (3d clocks) out the box.

Its not extreme cooled but only runs 52C max ever so can i flash bios to say EXTREME wihch is said not to exist lol, and what volts increase and clocks will i see, and will it cool ok as it is. ?

It does 468/1210 slight artifacts in 3d mark tests when new, i will try now its ran few months.

[drcrawn]

WOW. Nice to see this thread is ALIVE. Takes me back...

for those of you who are sub 25c on the gpu, best thing to do regarding cold throttle is to get a bios with 2D and 3D voltages set exactly the same as well as clocks. Just be careful you dont destroy your card, as the built in fail safe has been disabled in effect. Dont even think of doing this unless you have chilled h2o at least...
Check out omniextremeedit bios editor at www. mvktech .net. You upload your bios and can fiddle around with it in terms of voltage and clocks.

hi.. i got a Point of view 6800 ultra and the stock speeds are olny 370/1050..
dont know why maybe a new revision because i got a 6800ultra with only one powerconnector.. but i am sure it is a ultra and not a gt because on the package it says ultra and also in my graphic menu it says 6800 ultra
so i would need a POV bios with the normal ultra speeds @ 400/1100 or 425/1100
pls make me one... thnx

[humeyboy]

No way cause a ULTRA has to be at least 400/1000, they said this publically to fool ATI as we all know then manus made it 400/1100 with some making them 425/1100 like my Chaintech, which btw unlike some makers like BFG dont claim to be 10% o/c, Nvidia dont tell makers what speeds, they give them a range and that the range they work to, a ULTRA E HAS TO HAVE 450/1200, i can easily run more than this now with no mods and 100% stable in 3d marks with no artifacts or bit higher again like 470/1220 with artifacts in 3d mark but ok in games, my temps dont seem to increase, obv i could work this better with modded bios, im think that over for now.

There used to be point of views avail to preorder where i shop online and it wasnt that low it was approx same as others ie 400/1100, but most of the ULTRAS aint appeared as of lack of them so they have removed most makers from list.

[Paxi]

jeah.. but it couldnt also be a gt because a gt is @ 350/1000 clock speed

[humeyboy]

did you buy new or someone or you flashed the bios ?

[drcrawn]

jeah.. but it couldnt also be a gt because a gt is @ 350/1000 clock speed

Yeah but it couldnt be an Ultra cause it isnt set at 400/1.1 and doenst have two molex. Sorry, but that's the truth. These two things are required to be called a Ultra. Did u buy this from a store?
Have you tried overclocking it to 400/1.1 first? Is it stable?
Why don't you take off the heatsink and look at the chip itself. It will say either Ultra or GT.
Tell us if it will run 400/1.1 stable, like really stable, in a hot room etc under full load for hours.
I'm not going to speculate, but that sounds kinda fishy to me.

to drcrawn: i oc to 400/1100.. i can run any benachmark with it.. i tried 3dmark05 with 370/1050=4629, an than 400/1100=4800, and 3dmark03 370/1050=11636, and 400/1100=12014, no problems so @ benchmark... but i tried far cry than with 370/1050 everthing works perfect @ 1280*1024 every detail on very high and 2*anistrophic filtering... than i tried with 400/1100 there was no difference.. but after 15min playing my monitor freezes and there were many weird lines.. than i reboot and adjust back the stock clocks @ 370/1050
i asked my friend who ordered me the card from amerika and he meens that its maybe one of the first ones that got produced because i alredy got this card since august or september...
but tommorow he will give some more information.. maybe i just have to flash the new POV bios and than everything is ok.. but i meen there was no improvment in games between 370/1050 and 400/1100 so maybe i just let it like it is

PS: i wont remove the heatsink at the moment.. because than i would have to remove many other things to get my graphic card out, like some tubes of my watercooling and thats not very funny and i am really sure that its an ultra because if its a gt it wouldnt say its an ultra in the graphic menu..

Do you know how to copy your bios using nvflash? If so, can you send me the bios through email? I can take a look at it and tell you what's going on...

[Dirt]

Here you can find the only thing you´ll ever need to mod your 6800 BIOS AGP or PCI-E doesn´t matter:

sry.. no i cant copy it because i got no floppy drive in my pc.. is there maybe also another way to get my bios..

[Paxi]

and thx to dirt.. but i already know this programm

[carmatic]

uhh hi guys first post here, im a bfg6800 ultra oc user, and ive been using noxis's 4501200 bios so far and so far thats the best ive used... i tried to mod the default nvidia bios's using nibitor to give 1.5v vcore 450/1200 speeds , but noxis's bios is always faster and more stable at the same clock speeds no matter what i try...

well, like the 4501200 bios is so old already , are there any new bioses out there that are better than this?

thanks, first post

[Dirt]

Just check here: http://www.mvktech.net/index.php?option=com_remository&Itemid=26&func=selectfolder&filecatid=4

[carmatic]

ok thanks, now im using a nibitor-modified bfg bios (thougth that its the safest since its the same brand as my card) .... seems to be on par , like 460mhz core and stuff with the noxis bios... i wonder where is noxis nowadays, or extremetheme... theres gotta be a supa dupa bios somewhere....

how do you guys go at bioses, like do you just get the newest one you can find , mod them, etc etc?also do i really have to use nvflash version 442, and not the newer ones?

[humeyboy]

If it works why change it.

I can easily run 3d mark 2005 with no artifacts at 460/1219 with no mods to Chaintech 425/1100 Ultra, it tops in coolbits to 470 core as you cant pass test to apply at 471 core but its gets artifacts in 3d mark (similar if memory is above 1220) so prob 1.5v instead of 1.43v would help, my temps dont seem change much, always approx 52C on load in room temp of 21-23C

A Ultra Extreme is only 450/1200 anyhow.

[Dirt]

Well I downloaded the latest BIOS and modded it. My card does 6800GT 462//1208 Max

nvFlash 4.42 because it is the onlyone that work with "ignore vendor" "ignore size" bla. bla. something like that :)

[The Mutt]

Dirt what bios are you using? I also have a Sparkle 6800GT and mine only goes to 434/1200

That might be a volt problem. I could mod a bios for you if you want. Just tell me the make and what you want me to do.

[The Mutt]

I have already modded my own bios and it works because before I was at 420/1200. But before I would get artefacts before it locked up but now theres no artefacts then it suddenly scrambles the picture. Thats why I wondered what bios he was using. Oh btw I´m on watercooling and my temps never go above 60c.

I'm being cheated out of the performance my cards can offer.

BIOS 5.40.02.31.03 NV40 with HSI = NV45

I went from air cooled to watercooled and they can run at;

450 and 1200 stable on both 2D and 3D.

When I use my water-chilling system I can get;

480 and 1300 stable.

Any help from an experienced modsman would be appreciated, whether it be a hardware or software mod, I can do both with proper guidance.

I will be getting 2 more Prometias in the very near future, and I will custom fit them to the GPU's. I just want the max out of my machine.

Now with my Gainward PCX 6800GT i run 465//1225 24/7 whithout any problems it idles @ 42c and Maxes @ 52c after hours of playing. I use 1,5v bios with 465/1225 as default.

[EQuito]

nvm I just did it with -5 -6 parameters since -p -u didn't work for me new bios allows my card run default 450/1200 in 3D mode :D
Congrats! is that the PCI-e version you're talking about? if so, could you send me the bios file please?

or if anybody else has an OC bios to use on my eVGA 6800U PCI-e and want to send it, I'd really appreciate it. TIA

:toast:

equito(at)hotmail.com replace 'at' with '@' :D

[Whizzz]

Can anyone help me mod this card?

Is the BIOS I have relatively close to other 6800 BIOS's mentioned in this thread? Can this BIOS be altered to increase my voltage and fix the 25C temp problem I get when I use my water chilling system? What about a hardware mod?

I need your help!

[overclock]

Hello,

I want to backup my BIOS card with nvflash but I have the message "PCI bios not present
note : this program can only be run under DOS"

I typed nvflash -b origine.rom in MS-DOS mode (under Windows XP then in safe mode). And I tried other commands like nvflash -c (check)...and it does not work too. It seems that nv flash does not work with my BIOS card.

I tried nvflash 4.42, 4.46, 5.13 with the same result.

On the other hand, I managed to backup the BIOS with Xbios Editor. But that does not solve completely my problem since I cannot flash the bios. And OmniExtremeEdit FX 1.5 does not find any information when BIOS is loaded.

So, would you know how to make nvflash work ? Or what other tool could I use ?

My card is a Gainward 2600 Ultra Golden Sample and the present BIOS version is 5.40.02.15.06.

In MVtech site, I found the same BIOS version. I explored it with an hexadecimal editor and I do not find 2D and 3D voltages and frequencies. I have read that GPU 3D voltage is located int E683 address, 3D GPU frequency is at E56E address and DDR3 frquency is E573 address.

So, would someone know where to modify the 2D and 3D voltages/frequencies in 5.40.02.15.06 Gainward bios ?

Thanks for your answers.

[EQuito]

overclock,

You need to flash from a DOS bootable floppy.
Read this: http://www.mvktech.net/content/view/15/37/

As for the voltage questions I don't know, I'm a newbie at this so I need help myself... :D

[overclock]

Thank you, nvflash works now. It did not work because I used it either in MS-DOS in Windows Xp or in saffe mode, but not with a bootable floppy.

But, all advice concerning the gainward Bios mod is welcome.

Would you know how to protect oneself in case of accident when flashing ? I have read using a PCI card or using a bootable floppy disk with autoexec.bat containing nvflash -f -5 -6 backup.rom, which loads automatically your original bios file if the card does not work anymore. Would you have tested it ?

Thanks.

[Tony420]

I dont really want to search this whole thread so can somone point me to the best BFG 6800 Ultra OC bios? Is there any bios's for this card with the GT mem timings but still an ultra bios? thanks!

[overclock]

Hello Tony,

You can visit http://www.mvktech.net/index.php?option=com_remository&Itemid=26&func=selectfolder&filecatid=4

You will find many Nvidia bios but I don't know which is the best for BFG 6800 Ultra.

[Tony420]

too many bios's... id rather use one that somone has gotten thier best results with...

[[XC] moddolicous]

I can mod a bios for u, but I dont know how to do the mem timings/ or if it will be safe at those timings. Just post what u want me to do and the make of the card.

[Tony420]

its a bfg 6800 Ultra OC which is the reference nvidia 6800 ultra. I use GT bios's for the timings and no 2d profile...my only question is which is the best bios for the default nvidia pcb?

[Umek]

My 6800GT only make 375mhz for the core, if I put the bios 1.4vwill be better? where download the bios?

thx guis my english is bad :(

thx guis my english is bad :(

With the 1.3v that a 6800GT is normally set at, I am surprised you only manage 375. Especially since my 6800LE works no bother at 400 with same 1.3v.

Also, no need to get a special BIOS for increasing core volts to 1.4, since all 6800GT cards already have the ability to set GPU at 1.4v in their own original BIOS. And the simple change can be done with NiBiTor v2a.

I must warn you however that some 6800GT cards don't like 1.4v on the GPU, so you do it at your own risk !!!!

[Gray Mole]

I've got a BFG 6800 Ultra OC, and while I'd rather do a voltmod for the core, I would like to know if there's any word on whether there's a fix for the temp issue...

I've seen the LN2 w/r on sli'd 6800's and they must have done something with it...

I've got a 507'd Prommie all modded to mount on it, and I'm just plain itchin' to get it on there, but there's not much point if it's just gonna throttle down...

Hey moddolicious, you wouldn't happen to be able to write in a fix to the bios and possibly a driver fix, if required, to make it happen would ya? :hump:

Gray

[humeyboy]

If you mean the higher than normal temp reading in drivers tab, that was bad drivers and is sorted in new oned on nvidia site.

I have a Chaintech 6800 U its 425/1100, not claiming to be 10% o/c

Ive ran it upto 460/1219 on standard bios and then i grabbed a modded bios from a GT as its got tigher ram timmings, even at 425/1100 the difference with the new bios with same volts was 300+ in 3d Mark 2005, then i modded bios to 1,6v but only get 465/1225 with NO artifacts in 3d mark 2005 as im on normal cooling, core never goes by 65C on load but i dont know how hot ram runs.

Nah it's the freeze bug I'm looking to sort out...

I've noticed a few using extreme cooling on their cards, and not having a problem...is that sorted out with new drivers, or is it still a bit hit or miss?

The freezer should run -50ish, so I need to be sure it'll work, and not throttle, at that kind of temp...

Guess I'll just have to get it hooked up and see what happens :)

Wel if you can provide yoru Original POV 6800U PCIE then we can do some changes so that it will run at better speeds... So backup your BIOS and attach it here so we can check. ;)

[DEVIL_DK]

here is it
and thanks

[nicepun]

Would it be O.K. to edit my bios to 1.5v?? I'm watercooled and video cards does go above 50c (on hot day). Have you heard of anyone killing their card by doing so?? Thanks.

[humeyboy]

1.5v is only just above the daefualt volts for a Ultra anyhow, i run 1.6v on air and no issues gpu temp on 3d never goes by 65C ever on full load with 465/1230

[humeyboy]

1.5v is only just above the default volts for a Ultra anyhow, i run 1.6v on air and no issues gpu temp on 3d never goes by 65C ever on full load with 465/1230, i only gained slight increase as i could nearly do this with normal volts, but remove standard cooling pads or grease and us artic silver 5 or ceramic

[[XC] moddolicous]

DEVIL DK, try this bios. I just raised voltages to 1.5v. (stock=1.4)

[nicepun]

I tried the pencil vmod from vr-zone I can only get 1.67v or 1.77v (went up and down the between 7.4K~8K ohms) which I think is too much unless you're doing -0c temps. I'll do the 1.5v on the bios, by the way 50c is my load temp. If anyone else has any input please go ahead. Thanks.

[Apocalipsis]

Hello Xtreme modders, I need that someone plz mod my original bios to get the max volts out of it, if possible make 2 files one for 1.5v and another with 1.6v.

Right now I'm using a hard mod to get 1.69v, hit the wall at 595 core with DryIce, I need more :D

Card is a Gainward 6800Ultra 430/1200 stock clocks.
