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.
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 ?
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.
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.
:(
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? :)
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
Wow, thx man, I'll give these a whirl in a bit.
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.
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.Quote:

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!"
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?Quote:

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.

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.
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:DQuote:

Make that bios, I'll try it in a few days:toast:
The temp was -120 C on the ATI x800 default volt.
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
Coolness! I'll try the core slowdown bios in a bit! Thx for all these xtremetheme! :)
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 :)
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?
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.Quote:

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.
This speed should be the new default speed for the card now, and the 6800Quote:
Originally posted by LardArse

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?
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 :)Quote:

This BIOS should give 1.5V in every case, and speed 390/540.
http://home.graffiti.net/abiosfile/6800UCVTEST.ROM
This BIOS should give 1.5V in every case and speed 600/632. (omg poor card :D )

Thx a bunch!
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.Quote:

This Bios is default @390 and the others at 410.
I set the bootup to 1.4V, maybe that works.
http://home.graffiti.net/abiosfile/6800UCVTEST2.ROM
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?

Here you go :)
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
im also looking for a modded 6800 bios :) non gt and non Ultra
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!Quote:

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
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?Quote:

Sorry dont know :(
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.
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?
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?
Thanks!Quote:

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!
Stylist
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...
What would be +0.2V = 1.6V?
tia
Stylist
Not available. I suspect the 1.5V setting is for 6800UE card.Quote:

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?
Great job xtremetheme, I've just one question in order to make my bios, where can I find nvchk.exe?Quote:

Edit : Finaly I found it :)
Great stuff xtremetheme, this will help a lot of 6800 users, especially the GTs :thumbsup:
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.
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.
Here all you need.Quote:

Does anyone konws why my card starts throttling down to 350MHz during benchmarking?
Anyone knows a solution?
Thanks. My 6800Ultra bios is slightly newer, 05.40.02.10.00 and dated May 21 2004. I'd be happy to email it out if anyone wants it. I know there's newer versions out now, anyone have a newer bios?Quote:

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?Quote:

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
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.
Is the PointOfView BIOS for the 6800 Ultra or GT?Quote:

For the ultra ;)
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 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 );)Quote:

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 :(
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.Quote:

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...
Here the great file from bmg: http://rycky11.free.fr/Forum_Hardware/6800u13.zip
my ultra bios is 5.40.02.03.00, I assume this is quite old..? anyone know?

"...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.Quote:

With version 4.46 the parameters doesn't work.
Thank in advance,

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. :(

In this zip file you 'll find nvflash version 4.42 ;)Quote:

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.Quote:

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
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...Quote:

Crazy things in 03 and eventually froze in mothernature. Think someone can edit this bios to 400/1100 1.42 vcore?
I figured out how to edit properly.
Anyone who wants it here it is.
PNY 6800 GT
400/1100 and 1.4 vcore.
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 :)
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.Quote:

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?!
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.
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?Quote:

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

nvflash.exe -f (biosname.rom) -p -u -2
If will flash for sure that way. Or just change yours for motr vcore.
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.
http://home.woh.rr.com/alexthorn/Bios6800u2.rar
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.Quote:

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

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
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?
Its prolly the same bios you used before, just with his mods.
Anyone having a point of view GT bios with 1.5v by any chance?
post number nine is the modded GT bios i believe
