Util to edit the 6800 bios's?

[Noxis]

Anyone made or know of a Util to edit the 6800 bios's. I'd imagine it would be a pretty simple VB program now that the locations of the main values are known.

Anyone?

[xtremetheme]

I will release such a tool soon. :)

Ah thought you might ;)

You managed to find things like fan speed, mem timings etc?

Woow that is very good news :-)
Been looking for that as well!

I have no idea about fan speed, my card doesnt even have a fan anymore lol.

I added editing memory timings but only for 5700/5900 class, i dont have a 6800 so i cant test if the values i look at are right.


Well here it is, a easy to use BIOS editor for new gen nvidia cards!
http://home.graffiti.net/omniextreme/oee10.zip
:)

Supports editing Speed and Voltage settings on 6800/U, 5900/U/XT, 5950U, 5700/U. Timings on 5900/U/XT, 5950U, 5700/U.

Better use an fresh unmodded BIOS, a previous modded BIOS may not have correct voltage display.

Maybe not all BIOS are read correctly so dont cry plz. ;) But thats also written in the program. Tell me what doesnt work and your BIOS and i can look if i can fix it.

Esp. would be nice if some 5700 owner could give feedback, it looks like some 5700Us can even have up to 1.5V

I hope that will make ppl happy who dont like hexeditors and save some time :)

Is it possible to edit 2D speeds in bios?

5700 and 5900 yes, 6800 i dont know are there cards which use a 2d speed?
All i read from ppl is that the 6800 have the same speed in 2d and 3d.

[Goldlocke]

uhm,...I mean the "throtteling speed". Where is the throtteling speed set? In the bios I assume.
Would it be possible to stop the downthrotteling by setting this speed to the same as 3D speed?

I tested your editor. I think it doesnt show the voltages of modded bioses accurately. It only shows 1.4V max. in bioses which set 3D voltage to multimeter-approved 1.5V.

Throttling speed is labled 2D/3D in my editor. And 6800s use their stock speed as throttling from what i heard.

Ah. OK, but on my GT I am not able to change the 2D/3D clockrate setting. Only the 3D. :(

With the stock speed i mean the 3D setting. The value you enter there should be the one your card throttles back to.

[Sir Random]

Great stuff xtremetheme, this will be a very popular tool.

Thanks for sharing it :).

EDIT:
There appears to be a bug in the program for 6800s, the 3D speed shown is actually the 2D speed.

'Detonator' has reported it on OcUK and I've noticed it too.

Posted by Detonator
There is a bug in this tool,actualy if I do a 450/1250 bios, editing a 425/1200 bios and flashing the card ,after the bot the coolbit show 450/1200 2D so far is ok , but on D3 still 425/1200 seem like dont take any effect on D3.....Some one should tell xtremetheme about this bug.. I dont have any account on Exstrem forum and I cant contact him....

My BIOS shows up as 400/550 in the editor, but that's my 2D speed, my core is actually at 425 3D default.

[Gwar]

I love it..! Thx

Here's my Club3D Ultra BIOS:

I don't know what card 'detonator' has :(

EDIT:\
Noxis' modded (+0.1v) BIOS shows as 1.4v with the tool, but Noxis says he tested it with a multimeter and it is definitely 1.5v.?

Yep definitly 1.5v (well 1.52v as it floats up) my card does 470mhz core with it, so unless its some kind of super GPU i got in there...

Noxis, could you please make a 425/1.2 1.5v BIOS?

3DMk03 froze in Nature at 450 core (@ 80c+), so I don't want to try the 450/1.2 1.5v BIOS until I've checked temps at 425 with 1.5v.

xtremetheme I am sure is going to shake the bugs pretty quickly, best to wait for that :)

[Zombie10k]

Xtremetheme, the stock 6800GT bios's show up with 1.4v under the 3d settings, not 1.3 like stock.


I uploaded the stock BFG6800GT rom in case you didn't have it.

That is correct because the BIOS says the card will have 1.4v in 3D.
1.3V is for the throttling.
Have you measured the values using a multimeter?

New version should fix the 3D Speeds for 6800Us.
But my webspace now exceeded traffic it seems (dang thats only a 200kb download, how many people got there lol), so you have to wait a bit i hope mavke answers me soon.

[Sir Random]

If you need webspace, I'll host it for you.
Just email it to me at random@eircom.net

[xtremetheme]

Thx thats very nice. I sended the file now to sir random.
In Version 1.1 6800U should have correct speed setting, all 6800 card should have 2D speed shown, (although i dont know if all cards use them), and i renamed the 2D/3D to Throttle, as it did confuse ppl :)

[Sir Random]

Here it is:
OmniExtremeEdit FX1.1.rar (http://www.handspun.utvinternet.com/daniel/OmniExtremeEdit FX1.1.rar)

Thanks again extremetheme, gonna try it out now :)

[thompson5439]

Thanks alot, you are a GOD.
I have a BFG6800U water block version with default clock speed of 470 and could not get it to run on my Asus A8V MB. I even RMA'd the card to BFG and new one would only run 3D at 440.
It is not a power supply problem, I bought a $200 PC Power and Cooling 510W power supply. I have enclosed the orginal BFG bios.

I used the editor to increase the voltage to 1.5 on my 6800. Oddly enough, it didn't improve overclocks any. Temperatures remain in the 60s most of the time. Frustrating, I can get 380 on the core, but I can't even get 750 on my memory completely artifact-free. A lot of people are getting 800. :(

EDIT: Nevermind, it does get into the 70s.

I get a lot of people saying that on their Original 6800 GT the Tool is reporting 1.4V on 3D GPU. While they are expecting 1.3V...

Can this be looked into?

[detonator]

Finaly I can post:)3 days to activate my account...
Ok I edited a bios from a fresh XFX 6800ULTRA 425/1200@450/1200 V1.5 3D
to test it,but I got ramdom frezzes...on 3DMarck 2003...
So I flashed back to Noxis's bios 450/1200 and everything work great again....
Ok now Coolbit show the right frequenzy, but I think the voltage dident take any effect ,stilll 1.4on my guess ,that why I got frezz.

Thx for reporting ppl.
The thing with the 6800GT is strange.
The Editor shows what the BIOS says and on every 6800GT BIOS i have seen it says 3 modes with default values 1.4V , 1.3V and 1.1V.
First of all why do people expect 1.3V to be the standard of 6800GT?

Can someone with a unmodded BIOS and a GT measure what V it gets when running 3D ?
Can 6800GT people overclock higher if the change the 3D Vs ?
Can they overclock higher if they only change the Thrtl Vs?

A guess could be that the 6800GT only uses 2 modes, the 2D and the mode labled as "Thrtl." in my editor is their 3D mode, which is at 1.3V

[warhorse]

hi, dudes,
i have a xfx6800gt, and when i run the program its says the same things, 1.1v for 2d, 1.3v for thrtl and 1.4v for 3d, I changed mine to 1.4v for thrtl and 1.5v on 3d, i kept 1.1v for 2d, everything worked fine and i ganes 25mhz extra and now after running aquamark and 3dmark2003 then doing a detect optimum frequencys in coolbits im gettin 429 core and 1.19 mem, befor i only got 401 and 1.12, so after this i tried changing the thrtl to 1.5v aswell and as soon as i started a game it crashed, therefor i agree with xtremetheme i think thrtl is the 3d mode.

also can sometell me why in the verson 1.1 of the program its tells me that my 3d core and mem speeds were 350 and 500 (i changed these to 400 and 1.15) but the bottom one called 2d says only 300 and 300, but when i used coolbits it told me my 2d and 3d speeds were the same, is this 300 and 300 the speed it starts up at while booting into windows.

And by the way this program rocks,

Hi, thx your reply is very valuable. :)

So your 3D and 2D Speed is always the same in coolbits? If i look at my 6800GT BIOSes i see that everyone has these 300/300 as 2D mode, so it seems 6800GTs dont use a 2D mode but always 3D instead.
Will be fixed in next version.

About the voltages i dont understand:
You changed them to 1.5V 3D, 1.4V Thtr and 1.1V 2D, and you could oc more.

Then you made 1.5V 3D, 1.5V Thrtl and 1.1V 2D and game crashed. So you think that 1.5V is to much and caused the crash?
What happens when you do 1.3V 3D, 1.4V thrtl, 1.1V 2D, can you oc the same?

[detonator]

ok this is a XFX 6800 Ultra Bios.standar:
425/1200

[warhorse]

hi again,
right i did the test you asked mate,

on 1.1v 3d, 1.4v thrtl, and 1.1v 2d, same overclock as 1.5v 3d, 1.4v thrtl and 1.1v 2d.
on 1.3v 3d, 1.4v thrtl. and 1.1v 2d, same overclock again.
on 1.4v 3d, 1.4v thrtl, and 1.1v 2d, same overclock again.

only when i push the thrtl up to 1.5v does it crash, so i do think having 1.5v on the thrtl is to much for the card.

on the above settings using auto detect in coolbits i always managed an average optimun frequency of 428 core, and 1.19 mem.

when i put the settings back to there original ways, 1.4v 3d, 1.3v thrtl, and 1.1v 2d, i only auto detect in coolbits optimum frequencys of around 406 core and 1.15 mem.

therefor i think the thrtl is the 3d setting, (but dont take my word for it, i know :banana: :banana: :banana: :banana: about bios's).
It just seems the 3d setting does nothing at all.

i hope all this helps you.

[Sir Random]

Could you try 1.3v throttle? That would help confirm your theory (if clocks are lower).

[warhorse]

i did try a 1.3v thrtl.

when i put the settings back to there original ways, 1.4v 3d, 1.3v thrtl, and 1.1v 2d, i only auto detect in coolbits optimum frequencys of around 406 core and 1.15 mem.

It looks like you're right about the "thrtl" actually being the 3D setting, but my Ultra shows 1.3v "thrtl" too, and it's supposed to be 1.4v 3D?

[warhorse]

thats mighty weird. :confused:

Your Ultra is shown correct, 1.4V 3D and 1.3V Thrtl. Its just a thing of 6800GTs, new version will show them correct.
(And 6800NUs? Anybody got an 6800NU?)

I have no idea, maybe the BIOS you modded before was not clean or you didnt made the 2D value the same as the 3D, like Noxis had in his BIOS. Maybe your card needs that for some reason.

I used the xfxultra.rom you gave me, opend in my editor and changed 3D V to 1.5V and the 2D & 3D values to 450/1200.

Maybe its the same like with the 6800GTs.

[thompson5439]

On my BFG6800U the new 1.1 reports 3D at 300 300 and 2D at 470 550. The later is correct for this card. Your old revision did report the correct 3d clocks and 2D.
Any way the 1.1 revision does work.

I have a BIOS that will not work in the Tool...
This is of a AOpen GeForce 6800 GT 256MB 350/1000 .
BIOS Version 5.40.02.15.02
I have attached it.

[warhorse]

thats very strange, because the bios on my xfx 6800gt is exactly the same one, BIOS Version 5.40.02.15.02. and my comes up fine.
when i tried yours it said vgpu not found and clockrates not found, very weird.
ive included my original bios with this post (i hope), try it if you like. just select rename and remove the .txt bit.

[warhorse]

also here is my modified one, it has 405 core and 1150 mem.
it has 1.1v on 2d and 1.4v on 3d.
on my card i can set the core up to 425 and the mem up to 1200, but i do the rest of the overclock through coolbits,(just incase anything goes wrong or i push it to far).
do the same as the last one just select rename and delete the .txt bit.

I notice that when changing a 6800 Ultra from 1.4V to 1.5V using OmniExtremeEditFX v1.2 that 8201 is changed to 9603. I would have expected it to just be 8203 for 1.5V. Is the change to 9603 correct?

[Desmondo]

First of all thank you Xtremetheme for the Great tool and for supporting the FX users!

I have an XpertVision (Nvidia reference) 6800NU which overclocks pretty well: 400Mhz Core/900Mhz Mem (with Powerstrip). (3DMark 2003 Score: 10982:banana: )

I wanted to mod my bios just to avoid using a tool to change my core/mem frequencies (and see if the core overclocks more;) )

I tried the following versions:

1.2 Results: -can't change 2D clock speed
-3D clock displays correctly
-can't change thr voltage

1.1 Results: -can change both 2D/3D but 3D speeds displays incorrectly
-can change thr voltage.

Sry for the n00bish question but are these settings correct?
3D voltage: 1.4v
Thr voltage: 1.2v
2D voltage: 1.1v

Thx

PS: Im currently on a MS Server2003 course :D , but as soon as I get home I'm going to link here the bios.

Yes, the 96 is just like a comment which describes what the 03 setting means.
Original vendor BIOSes use the 96 if their card is 1.5V by default. 8203 gives the same result, but a stranger (or my program ;)) would think that the 03 means 82 = 1.4V, when not knowing someone modded the BIOS.

8202 -> 8203 works but is a lazy way ;)
Thats why my program shows not the right voltage on handmodded BIOSes which didnt change the comment.

Hi, good to hear someone with a 6800.
I based handling of 6800 like on the 6800GT.
6800GTs always use the same clocks, that why i took their 2D setting away, as they where not used anyway.
Or does your 6800 use different 2D / 3D Profiles in the drivers?
6800GT also dont use the thrtl voltage so i took them away from the 6800s also.

I am not sure what V mode the 6800 in 3D uses, but its easy to test:
With 1.2 change the 3D Vs to 1.5V and see if you can oc higher.
Or change them lower to 1.2V or such and see if you cant oc good anymore.

Yes I have different profiles for 2D/3D on the 6800Nu if my memory doesn't fails.

(Maybe 2D runs at the same base clock speeds, but I only set the 3D part when I'm overclocking. I don't think 1.1v should be sufficient even in 2D, or am I wrong? Or should i just set the 2D voltage to 1.4 or 1.5 too and syncronize my clock speeds?
Example: 1.4v for 2D 400/450 and 1.4v for 3D 400/900?)

What does the thrtl voltage for?:help:

Thank you in advance.
Ps: Still I'm going to post my bios first, just for sure;)

What are your speeds in 2D profile then? Can you change your 2D Profile speeds? (in driver)
Thrtl is the mode the card switches into when its overheated or doesnt know if it has to deliver 2D or 3D mode.

My 2D Profile setting are the same as the 3D settings (325/350) and yes I can change the 2D profile speeds (in driver).

It would be nice to change the thrtl voltage too, because sometimes between 2 tests in 3DMark 2003 the card switches to suspended mode. (not because of overheating issues for sure)

If you change the settings in 2D profile and apply, what happens then, do the values from the 3D profile also change?
Or do the 2D values change when you change the 3D ones?

About the thrtl voltage im not sure unless someone answers me on the 3D voltage.

Can you use voltages like 1.35, 1.45, etc?

At 1.4vgpu, my PNY 6800 GT clocks very well, but heat becomes an issue due to the increased voltages.

No sorry you can only use voltages the card offers.
But your card could like watercooling :p:

darn, I thought it would work since I could change 1.3 to 1.35 in the text box of the program. Looks like I have to cool her some more!

Anyone know if there is a way of checking a Bios file to see if Fast Writes is enabled?

Also how do you tell which Bios version you have?

Thanks.

If I change the settings in 2D profile the values from the 3D profile doesn't change. So it is separated like on my "good old" 5900. The memory settings are the same. If I change the memory in 3D, then it is changing in 2D too. But I can set different frequencies for 2D/3D core.

I think the 3D voltage is correct at 1.4v, but i don't know if the 1.1v for the 2D is OK?

Did u check my bios?

Ok then i will enable 6800 to edit the 2D core. :)
I dont know about the voltages, it could also be that the card gets 1.2V in 2D. Someone with a multimeter could clarify this.

Thank you!:cool: And as I mentioned it would be pretty cool to change the thtr voltage too (which I could't set in 1.2 version of your tool). I should set that voltage to 1.4v because I think this causes the most of the problems: "Playing for three hours without a problem or artifacting then quiting from the game freeze" or "sometimes the card goes standby mode between 2 tests in 3Dmark 2003")

Thank you in advance:D :toast:

[Desmondo]

Xtremetheme!

I tried the first version of your tool (1.0) and it's perfect!:banana: (almost;) ):

-I can set all the three voltages (I really need the possibility of setting ALL three, so its fine!)
-3D speed is detected correctly! (325/350)

The only thing I need is the 2D profile setting (also 325/350 base). So could you please enable the 2D setting in 1.0? That should solve my "problem"!
Thx:worship:

[xtremetheme]

Ok 1.3 has now your proposed changes for 6800.
Also it has support for 5800/U, 5700LE, 5600/U/XT, 5500, 5200/U.
http://home.graffiti.net/omniextreme/OmniExtremeEdit_FX1_3.rar

Mavke when you mirror this, can you include the release notes in the txt file you add to the download? That would make the txt a bit more informative.

So my tool supports now:
- 6800U/GT
- 5950U
- 5900/U/XT
- 5800/U
- 5700/U/LE
- 5600/U/XT
- 5500
- 5200/U

Cards im missing right now are the 5900SE and the 6800LE, correct?

THX Xtremetheme:banana: But:(

Thtr (which I set to 1.4v) doestn't stick. I set all the three voltages to 1.4v then when I reload the modded bios it says Thtr voltage 1.2v, so it didn't saved:(

2D core setting is now available (the memory not). But maybe I shouldn't need that or am I wrong?

Arghh, good you reacted so fast. :)
I replaced the file with a correct one, dowload again.
If you cant keep seperate 2D / 3D mem clocks in your driver, changing them in BIOS would have no effect, as the driver will always only use one.

Man it's working!:banana: THX! I'm gonna try to falsh the new bios and report back!;)

[Desmondo]

Xtremetheme you did it!:banana: :banana: :toast:

Now I can I set all the tree voltages to 1.4v (and they "stick"!!)
Coolbits2 shows 400/900 in 2D and 400/900 in 3D too.

Thank you :worship: :worship: :D

[DMylonas]

Xtremetheme i have a Chaintech FX5700U and i have 2 problems with your program.....

I can't change the memory values......

[DMylonas]

and when i try to change the momory timings i see the following message and some strange numbers for timings........

[xtremetheme]

Hi, you can only change the 2D mem speed because 3D or thrtl would be ignored anyway, try changing the 2D speed and your 3D mem speed should also have the same value.

The message shows that you are not allowed to edit timing A, which obviously you cant.
The numbers represent some of your timings. Making them lower will give you more performance, making them higher should allow you to oc the memory higher.
I would try to test a timing changed BIOS with vgabios.exe first.
vgabios will load a bios temporarly under dos so you can see if your pc would crash with changed timings.

[DMylonas]

I try the vgabios.exe at dos mode writing the following...

vgabios.exe -f5700o.rom -t0

but it gave me the message "Checksum Error!"....

[xtremetheme]

Hmm try without the -t ?

Or use nvchk.exe on the BIOS, and post if it wrote a new checksum.

[DMylonas]

Again the same message.......

[DMylonas]

the same without -t....

[xtremetheme]

Hmm pfff nvchk says the checksum is correct, no idea why vgabios does this crap. Have you tried accessing the bios from your harddisk?
E.g. leaving the .rom on your c: drive and not on a floppy?

[DMylonas]

I use Windows XP Pro with NTFS and i can't se drive C: from dos mode.... I send you my bios, to test them....

[xtremetheme]

Originally posted by DMylonas

Hmm i cant see a failure, can you use vgabios on the unmodded bios?
And you set your memory speed to 62mhz in the modded one.
You use nvflash to read them out?

[DMylonas]

No i can't use vgabios with the unmodded bios... I take the same error...

I set the memory speed to 1000mhz from OEE1.3, and the program set it to 62mhz.... i found a little bug on your program, i think :)

Thx i will look into this :)
But you know the mem values must be multiplied by 2, so i would set 500mhz instead of 1000.

And a late mirror of version 1.3 :-)

[DMylonas]

"xtremetheme" you have right for the memory multi, it's ok now, but for the noobies you can do something like the following....

[xtremetheme]

Yeah if it confuses people i will do that.

And about the 1000mhz bug, its a limitation in the FX5xxxs BIOS structure.
You cant mod a BIOS with clocks higher than 655/1310. But i doubt somebody will reach that anyway :P
With 6800 series you can go to 65535/131070 mhz :P

[enduracell]

thanx for ur tool xtremetheme just tested on my 5600NU Prolink w/ vgabios and it works great.
Some things to notice also. the ASUS bios and Prolink ones can modified and play with my card just fine (rev02 prolink's play too, though my card is rev01) but nvidia's reference one vgabios give me checksum error (and its for rev01)
Prolink’s rev01 BIOS the 2D clocks isn't detected right (shows values from 3D) but I modified it and it works fine.
I also changed timings from default 13-15-10-4-4 to 9-12-6-3-3 and it plays nicely w/o effecting gram oc mach and gained about 300marks at same speeds. The ICs is Samsung ones (don't remember part number). Is this sound right to u? or ver 1.3 can't detect gram timings correctly on this series.
Thanks for ur tool again great work. :toast:
The Prolinks re01 default bios is this one (http://www.mvktech.net/request.php?110)

Hello. Great tool, but on my GT its exactly the same as Desmondo tells. There are two different values for 2D/3D Core, but with your tool, i still can only edit one. Here (http://home.tiscali.de/boubel/6800/bios/aopen_gt.zip) is my Aopen 6800GT Bios.

Hi, i disabled that with purpose on the 6800GT because ppl said their GT always has the same clocks in 2D and 3D.
If you say you can have different 2D / 3D, i think i will enable it again.
But can you say me which clocks you get in 2D mode?

[Riemen]

Sorry, that was my mistake. I Mixed it up with the manual overclocking settings, where you can set two rates for 2D and 3D.

[Desmondo]

A vote for your topic (and for your great job) Xtremetheme!;) :D

Anyone ever come across this error with Nvflash "Cannot Program A Non-Page Boundary" ?

I have a Albatron FX5900Xt and i use a original nVidia BIOS from FX5950Ultra ... and after all i reach 500Mhz1,5v GPU/ 950MhzMemory whit more relaxing latency.
I have a Quadro FX3000 BIOS, but your program can't open and edit it... :( Can you fix this ?!
I use thease sites:
http://www.hwspirit.com/downloads.php?for=nv

[DMylonas]

I flash my Chaintech SA-FX5700 Ultra and now the default clocks are 500/1000MHz with 1.5v@3D, 1.4@Thrtl and 1.2@2D...

Some questions are following:

- Now, my memory timings are 21-25-14-7-8.... can somebody tell me what to change for better performance?

- From where i can see if the GPU voltage changed?

- My bios version is: "4.36.20.18.05", but i found from Gainward the "4.36.20.23.00". If i flash my Chaintech with Gainward's bios everything will be ok then?

[enduracell]

u have to test it w/ vgabios first. In my case not all bios suited for my 5600 NU. I use 9-12-5-2-2 but I don't know if the prog recognizes (and sets) the timings value correctly in 5600 series.

DMylonas
Making timings lower should give more performance. Making them higher should allow more mem oc.

[DMylonas]

If we test a bios at VGABIOS and it's ok what message we take back???

What is the best? Fast memory timings or bigger memory oc?

[enduracell]

u must load the BIOS with vgabios from DOS, if it is a success then u must load WIN98SE to do some test of the new BIOS and modifications. Do not restart u have to type win on prompt so the Win begins with the loaded BIOS. Press F8 Command Prompt only choice do ur staff if BIOS loads successfully (the string of the BIOS appears type win and ready to goif the bios doesn't feet ur GPU either would not load @all or it will restart WIN before it enters.

[DMylonas]

I don't have Windows 98SE.... I use Windows XP Pro...

[enduracell]

with XP no go it works only in 98. so u can test it in DOS only. but may cause u trouble in getting in to OS, so have a flashback Disk ready with an autoexec and the like ready, just in case

[xtremetheme]

Exactly, remember vgabios can load a bios fine under dos, but at windows you can get gfx errors because the timings are too sharp.
Atleast you know your Card will boot into DOS so you can flash back.

[DMylonas]

At last i flash my cards timing from 21-25-14-7-8 to 19-21-10-6-7 and i put the freq to 1000MHz...

[enduracell]

I thing the values are ok. Remember ur GPU uses DDR2 and mine DDR (TC33) so the values sound right to me. Have u noticed any performance increase with the tighter timings in 3Dmarks?

[DMylonas]

Take a look....
Before modded bios: http://service.futuremark.com/compare?2k1=8029905
After modded bios: http://service.futuremark.com/compare?2k1=8039460

Modded Bios gave me +389Marks, with lower CPU, GPU and Mem...

[enduracell]

good ;) I took some points too (500) I just expected more, I guess I need more GPU clocks.

[DMylonas]

After a lot of bechmarks.... The best timings without any antifact was: 20-22-9-6-7 from 21-25-14-7-8....

It's time to do a vmod on my card :rolleyes:

Card: Chaintech SA-FX5700 Ultra 128MB

[Blind_GI]

Im having a little problem flashing here. I just took off nvflash 5.08 and put on 4.41v (I must have got a bad file or something, but this one works now) and tried to flash. But when I flashed it this is what I got:

Should I not put cwsdpmi.exe on the floppy?

damn i got the same error... even when modifying my backup.rom... seems to be that it doesnt like anything changed in the bios file

here is my GT backup file... try it maybe it'll at least let you flash back and have a usable card again

Will we ever be able to edit ram voltages using your bios utility?

[Çhrist0ph]

Here is a copy of my PNY 6800 GT BIOS for your site, keep up the great work!

[aoc007]

eVGA 6800 Ultra BIOS

For those of you that don't want to check I compared all the bioses linked in this thread, except all the ones from mvktech.net theres too many.

Mine and "N345" (the 6800 Ultra not UE) are the newest revision:
5.40.02.15.07, my eVGA BIOS might be different in some way but I guess its just trial and error to see which is best.

[AcUaViVa]

well somebody have a POV 6800 GT?

what bios uses?

[Mavke]

Well I would like to announce that xtremetheme has again updates his great tool. And I would also like to thank him for the great work :-)

We are now at Release 1.4.
You can find the download at http://www.mvktech.net
Direct Link :
OmniExtremeEdit FX v1.4 (http://www.mvktech.net/index.php?option=com_remository&Itemid=0&func=download&filecatid=69) - At mvktech.net


Release 1.4
--------------
- added display of effective memory speed, as it confused some people
- added support for 6800LE, Quadro FX1000/FX2000/FX3000

So with the latest update 1.5v in the tool = 1.5v with a multimeter?

Also the newest revision I've seen (checked with version 1.4) is 5.40.02.15.07 my eVGA6800U and the N345 BIOS are this revision. Do the Ultra Extreme BIOSes seem to clock better regardless of their lower revision?

[Richdog]

I had a scan and i couldnt see any concrete resuls of improved overclocks with 6800GT's. What boost in stable core mhz are you guys getting by using 1.5v?

[p4z1f1st]

could someone tell me, where the measurement-points vor the VGPU on a GF6800Ultra are ? :)

For the 6800U it should be correct since v1.0. :)

[DMylonas]

"xtremetheme" i download the new version of your program 1.4 (very good the memory calculator), but i see the following.... where is the 1.5v?

And at the FX5700U the VGPU doesn't work...

As far as I know the 1.5V is only for 6800 Type of BIOS/Cards.
All the 5 series only can go till 1.4V.

[aoc007]

I think its working, I don't have a multimeter tho, guess well have to wait for someone to check with that, before my stable 3dmark03 bench was 455mhz now its 470mhz, helped me break 14k :)

xtremetheme is it possible to set 1.6v through bios?

No, 5xxxx cards can also have 1.5V, but not all cards support.

[p4z1f1st]

all FX5900 support 1.5V

my old FX5900nU and XT did :) (both flashed with FX5950Ultra-Bioses)

[aoc007]

Damn, I guess I'll need a voltmod has anyone done the volt mod yet?

[drcrawn]

ah, ok...xtremetheme, your 'backupx2.rom" does not have a 1.5v setting, yet when I flashed with it (2month ago maybe), i got my core to 500+, so it was noticable difference. Any thoughts?

opening the rom with v1.4
2nd edit, you are smarter than I, lol

edit: question has been answered by "mavke's friend" lol,

East bay area!!! Sweet, i'm from santa clara county....yes people have volt modded all these cards...if you are watercooled, and use the 1.5v setting, your 6800 should be hitting close to 500 core.

no, it says it does not cool the ram. a lot of ppls are talking abou this, but i would seriously wait i f i were u and see if they can even outperform the stock reference ultra cooler....

my ram is cooled by the stock heatsink, very ugly, very effective....1.30ghz is no problem with no extra cooling. ddr3 runs cool...i think both the mem and core are fairly volt limited if u can provide even decent cooling, (e.g. basic watercooling setup)

[aoc007]

I'm sure it cools better than the stock hsf given their track record with the vga silencer and it is made of copper, my vga silencer rev2 on my aiw 9700p feels alot heavier than the 6800.

Ah they finally updated the pics, I think the copper block could be bigger but then it might be too heavy. Uses all 4 mounting holes too, I'm glad I ordered one :toast: I dont think itll be here tomorrow but should arrive on monday I'll post results then, how much should lapping improve performance?

[dzuser]

xtremetheme,

Would it be easy to add the ability to change the manufacturer ID of a rom, so that people didn't have to force the flash of a rom from another manufacturer?

[xtremetheme]

Yeah sure i will add that. :)

[Mavke]

Hey xtremetheme,

I send you some mails and also the nVidia Quadro FX 4000 BIOS :-)
Can you support that one in the tool as well?

Regards,
Mavke

[blass]

does anyone have BFG 6800 ultra BIOS ? I have a 6800 gt BFG and in rivatuner it shows as a nv40[A1] CORE how do I chack if im getting 16 pipelines thanks.

[Mavke]

A GT has 16 pipeline :-)
And a Ulra also :-)
Only difference is the Core clock and Mem Clock!
I can send you the BFG 6800 Ultra OC BIOS if you want...

[blass]

Mavke thanks man.very kind of you but the reason I asked is beacuse I tried flashing the ultra BIOS on my GT and NVFLASH wasnt letting me it said the bios were for board nv41 and mine was nv40 I downloaded the bios from you website I think. and I wanna flash the ultra bios to my GT cause I think there might be more to it than just core clocks maybe MEMORY TIMINGS?? :)

[Mavke]

Well you can if you use the correct switch to disable the board version checking, you should read the Articles on my site about Flashing the BIOS!

[blass]

ohh maybe cause I have the new 6800 gt with the dual heatsync fan. ON my previous 6800 GT I had the heatsync fan with the heatpipes. (no fans) SO if anyone out there has the new 6800gt please send me your bios file ;)

[Mavke]

That is not the issue if you try to flash a GT to Ultra you might get that issue but you can remove that checking of the chip id with a -flag ...

And then it will flash without looking at that...
a:\nvflash -5 -f file.rom [Enter]
or
a:\nvflash -5 -6 -f file.rom [Enter]

[blass]

a:\nvflash -5 -f file.rom [Enter]

thats exatly what I did but I guess is not possible I have to wait till somebody finds a workaround to this cause everytime I tried it kept on telling me there was a board mismatch ID the one in the rom was 4008 and my board was 4007
a:\nvflash -5 -6 -f file.rom [Enter]

[p4z1f1st]

man, how do i flash with nvflash ?

it doesn't work !

i boot from the ms-dos bootdisk....

then i type "a:\nvflash -5 -6 -f [FILE.ROM]"

then nvflash shows me a lot of its options and commands and tells me 4-5times to "Press Enter to continue or Q to quit"....i always press enter (it doesn't matter WHAT i press, he always goes on with its F*CKING commands :mad: ) and then, after showing me its list of the supporting EEPROMs, it shots me out to
a:\

what i'm doing wrong ?

(btw, there isn't the "-f"-command listed....is it maybe another command, to flash the BIOS ?)

[Mavke]

Did you try WFFlash?

[blass]

yep! did both comands using wfflash and it kept on saying file 123.rom wrong size

[Kunaak]

"nvflash -e" to erase the epprom.

"nvflash -p -u -f -----------.rom" for standard flash.

"nvflash -p -u -2 ------------.rom" to force a flash.

if you use the erase epprom command, before a flash you can pretty much flash anything.
just don't reboot after erasing the epprom.
just enter a regular command to flash after erasing the epprom.

[blass]

kunaak I did that and it was a no go. on WFFLASH it said "THE FILE SIZE OF 123.ROM IS WRONG -f402':smileysex

[AcUaViVa]

can somebody make a ponit of view 6800GT BIOS optimized?

[Kunaak]

blass

I was talking about NVFlash, 4.42 in particular.
I never tried WFLASH.

look at the stick called "where to find various videocard bioses" in there is mavke.net or close, and you can find lots of versions of NVFLASH in that website, including version 4.42

for some reason version 5.08 just doesn't work for me, but 4.42 flashes anything for me.

[Kunaak]

AcUaViVa

extract your bios using NVFLASH from a dos boot disk, and post it here. theres tons of people that can mod it for you.

if no one mods it for you, I will.
it's no big deal, I'll change the voltages from 1.4 volts to 1.5 and set your clocks to 400/1000, thats a nice easy OC and will give you more start speed.

extract it by using this command.

"nvflash.exe -b backup.rom"

[p4z1f1st]

ah, ok, used wfflash :)

now i've a 1.5V-BIOS on my card :D (exactly 1.511V)

getting 470/1260MHz without artifacts and absolutly stable :)

(under a waterblock - max-temp under "live-load" -> 55°C after 15mins)

[blass]

OK I flashed the ultra XFX 6800 on my BFG and it worked. so far is working fine :) no problems here

Hello,

Here's my original BFG GeForce 6800 Ultra OC BIOS.

BFG GeForce 6800 Ultra OC BIOS v05.40.02.05.12 (http://www.hardnsoft.net/bios/nvidia/bfg6800u.rom)


Here's what happens when I open it in OmniExtremeEditFX 1.4.

http://www.hardnsoft.net/images/mods/bfgbios.jpg

As you can see my clockrates in 3D are "a little" off. Can this cause a problem? As it is the card seems to be stable at stock clocks, but I get 5-10 second freezes in 3DMark03(haven't tried any games yet). Should I go ahead and set 3D clocks to 425/1100 using the tool?

Thanks.

wow im having the same problem with my bfg gt... freezes every few seconds then just freezes for good

[BlackHawk2383]

my pny 6800U does the same thing...i have to use coolbits to set the 3d clocks to 400 bc anything over that and i get short freezes followed by a permanate freeze in both 3dmarks.

BlackHawk

[Mavke]

That all has to do with the older BIOS Versions on those cards...
This is generally fixed in the new BIOS versions (eVGA has already released them).

[p4z1f1st]

hm, i've a problem...

my Ultra doesn't like 1.5V....i can flash the UE-BIOS and it works fine...but i can't push ONLY ONE MHz more with 1.5V against 1.4V-default-bios.....and he freezes @ Doom3 with the 1.5V-BIOS....the freezes disappears when i clock down to 440MHz (@ sig: max stable-clock = 470MHz)

the max-temp is @ 65°C under my waterblock under load (mesuared with "DX9 Real-Time High-Dynamic Range Image-Based Lighting v1.2")

so, what could it be ?

maybe someone knows, why it doesn't like the 1.5V or knows a solution for the problem....

[DisposableHero]

how can i flash my GT with an ultra bios? i tried and it sais board id mismatch when i do put the -5 -6 commands

[Kunaak]

use the nvflash -e to erase the eprom, then don't reboot, and then use the bios flash to the ultra bios your trying.

[BlackHawk2383]

This is my bios number 5.40.02.15.07 Should i try to flash with another bios...i had freeze problems for away but they have seemed to go away but yet i still dont get good performance. I have a 3.0C at 3.75 1:1 and the graphics card at 440/1.13 and i only get 22000 in 3dmark01

6800s seem to suck for 3d01se, and I think trilinear might be forced on them.

Heres my evga 6800U bios 5.40.02.15.07 @ 1.5v works fine for 3d03 with 470/1.25 and I think I can get more.

[Warden]

A lot of people including myself have had troubles when flashing a GT with an Ultra Bios. There are some minor differences in the cards that could cause this. The Ultra uses Dual DVI and a Multispeed fan, the GT does not.

I would suggest using a modded GT bios with an additional .1 volts and perhaps an Ultra speed as opposed to the Ultra bios itself.

For example, with an Ultra bios my GT was unstable at 370/1100 but with a modified GT bios it was completely stable at 400/1100. With watercooling it's now running at 460/1200 with 1.4volts and bios settings of 450/1200.

Oh and for those having Bios issues I've found that the Leadtek bios is very stable on my evga card. You just have to deal with that ugly boot screen for a second :(

No matter if i use nvflash(4.41 or 5.08) or wfflash i cant update my bios for my pny 6800 Ultra. nvflash says it cant find a nvidia adapter and wfflash just says programming failed.

Hello, Im a XFX owner,now reading around I found the Version 5.40.02.10.14
the best bios for the 6800 Ultra,(i have the 5.40.02.10.04 on my XFX) , this is from Geinward, I edited the bios to 450/1200 gived the right voltag but then when I put this bios and I test the voltage with the tester the Voltage is still 1.40.V....
sem like the votlage dont work with the program.
can you cheak please? tnx.
just think with the same bios same frequenz I gained 200 point more point on the 3dmark 2003 with the geinward bios and under stok air the fan spin faster so the card is better cooled.
this is the final bios I suggest every1.

[DisposableHero]

are the bios revisions universal between companies? because eVGA has a 15.7 while you are talking about a 10.14

I am running a Swiftech MCW50-T on my 6800 Ultra. So far the 80 watt TEC seems to be keeping up as my idle temps are 14C and load temps are 28C-30C. My problem now is that the card is throttling at temps below 25C. I tried the Riva Tuner work around but it didn't work. I downloaded the OmniEtremeEditFX version 1.5 so I can edit my cards BIOS but I am unsure of what needs to be changed in order to work around the throttling. I saved my current BIOS using NVFlash and opened it using the Omni tool. There are options for throttling voltage and throttling core and memory speeds. Right now on the stock BIOS the throttling core and memory speeds are blank and the throttling voltage is at 1.3 volts. Am I supposed to alter these values to get around the throttling? Can someone point me in the right direction please. Also when I open up my stock BIOS using the Omni tool it shows my memory timings as blank? Is that normal?

I posted this in another section of the forums then I found this section so can anyone help me with the throttling? Do I need to just change the throttling voltage to the same as the 3D voltage to make it stop throttling? Thanks...

Hi,

I came across this forum will hunting on any type of vMod for my Gainward 6800NU. Come to find out that you can vMod is BIOS which is sweet.

I have read across the forums, and there seems to be a gray area on using the BIOS Edit on the 6800NU.

I actually downloaded the older OmniExtremeEdit 1.2, and read the "ReadMe", and it was looking for responses from 6800NU users.

I would like to know if there was any responses or issues w/ using the latest 1.5 on my NU?

I would be interested in helping the testing of this tool, if anyone is interested.

My current OC w/ stock cooling is 390/890 w/ a score of 11k on 3dMark2k3.

Once I open my BIOS in OEE 1.5, what values should I change? I noticed that there were 3 voltage area. Which should I change and to what value?

Any input would be greatly appreciated.

Well the 10.15s alone didnt fix the problem but i edited it and raised the thtl to 1.4 and 3d to 1.5 and in the bios i raised AGP voltage to 1.6 and i can now get 440/1.15 stable in far cry and doom 3!!! So the 15.07 bios it had didnt work for my card but yet it is supposedly newer? :confused:

Thanks for the pic. the pic is a little vague for me. Can you give me ball park of where the point is locatd. Is it toward the front of the card w/ there DVI port is, or toward the back where the power is located?

Also, for the voltage, do you change just the 3d? Or do you have to change all of theM?

I saved my current BIOS using NVFlash and opened it using the Omni tool. There are options for throttling voltage and throttling core and memory speeds. Right now on the stock BIOS the throttling core and memory speeds are blank and the throttling voltage is at 1.3 volts. Am I supposed to alter these values to get around the throttling? Can someone point me in the right direction please. Also when I open up my stock BIOS using the Omni tool it shows my memory timings as blank? Is that normal?

I posted this in another section of the forums then I found this section so can anyone help me with the throttling? Do I need to just change the throttling voltage to the same as the 3D voltage to make it stop throttling? Thanks...

Could someone plaese help me? In the OmniEtremeEditFX version 1.5 I can change the voltage for all 3 values 3D,Throttle and 2D. In the Core/Memory speed section I can only change the 3D and tthe 2D speeds. Throttle is an option but it just has dashes there and I can't change it. Also the memory timings are the same way all dashed out and I can't change them? Is that how it is supposed to be? If I am to get around the throttling issue what do I need to change? Do I just change the Throttling voltage to the same as 3D and it's done? Thanks

[Section8]

I don't know if you guys know this but throttling also effects 2D? If I go to PC Pitstop and run there test which tests 2D while my card is throttling I only score 100 points where if I run it while not throttling I score over 600?

I doesnt show throttling speed because your card throttles to the 2d value.
To get rid of throttling try set all voltages the same as 3d and the 2d clockspeed also to the 3d value.
Memory timing editing for 6800 is not implented yet but likely to come.

what that hell is the throttle for?? the higher the better right??:smileysex or does it up the voltage?? or does it slow down the chipset/?

It is throttling because my GPU is running under 25C. Whenever it hits 25C or under it throttles down because it doesn't understand why it is running so cold.

xtremetheme will I damage my card if I use the 1.5 editor and it says my 2d speeds are 11625mhz ?

[Section8]

I will flash my card tonight and let you know how it went. I already saved my stock BIOS with the -b command. To flash it I just need to type nvflash -fNEWBIOSNAME.ROM [ENTER] correct?

[reject]

the voltage changes wont work for me in 1.5 or a 1.4 i only have 3d speed displayed but 2d and 3d volts. ive tried every combo but i get major arts halfway through 3dmark and and artifacted bsod.
xtremetheme im gonna measure the volts with my dmm on saturday in the differnt modes but had anyone found this too?
yo section8 make sure your bios is 62kb. i flashed to a 61kb bios and took me a few days to get my card working, thanks to mavke :D

Thanks I just looked and the modded BIOS is the same as the stock BIOS 62KB. I have a problem though. It will not flash no matter what I try. I am using NVFLASH version 5.06 I have saved a copy of my stock BIOS using the nvflash -bBACKUPBIOS.ROM command then I edited it using the OmniExtremeEditFX version 1.5. I then saved it to the floppy with NVFLASH and tried several commands but nothing happens. I tried

NVFLASH -fNEWBIOS.ROM
NVFLAS -p-u-fNEWBIOS.ROM
NVFLAH.exe -p-u-fNEWBIOS.ROM
NVFLASH.exe -fNEWBIOS.ROM -p-u-2
NVFLASH.exe -fNEWBIOS.ROM

I also tried spaces in between the letters and still it just does nothing just shows me all the nvflash commands after I hit enter. I just tried using NVFLASH version 5.08 and still the same results. I can save my current BIOS mod it and when I try to flash nothing happens just keeps showing me all the NVFLAS commands?

Just change your 2d speeds to something more realistic....

Maybe when you copied the original bios from the card it was corrupt, try making a new a backup to edit.

Anyone? One thing I forgot is it says something about invalid keyboard type when nvflash loads and starts up. Could that be causing it not to work? I am using the Logitech MX700 Keyboard and mouse.

[Section8]

OK I got it to flash finnaly but:


I have NVFLASH version 5.08 and you OmniExtremeEditFX version 1.5. I made a backup of my BIOS by typing nvflash -b backupbios.rom and it saved it to my floppy disk. I then opened it using your BIOS editor and changed all 3 voltages 3D, Throttle and 2D to 1.5 volts. I also changed the 3D and 2D core and memory speeds to 470/1200. Then I saved it on the Floppy with NVFLASH and named it newbios.rom. I then went in to DOS mode and using nvflash typed nvflash -f newbios.rom and nothing happened but all the nvflash commands came up so I tried nvflash -p -u -f newbios.rom and still nothing happened. I tried several different commands and nothing happened but the nvflash commands popped up after each attempt. I finally tried nvflash newbios.rom and I think it worked. It said something about I should get a newer version of nvflash because it didn't recognize the file or something and asked if I still wanted to continue to flash to the new eeprom. I typed Y for continue and the screen went blank for a few seconds and then it said it was successful. I then CTRL+ALT+DEL and restarted my computer. Now when I go to clock speeds in the NVIDIA control panel it says 470/1200 even when I click set to default or if I click the NO OVERCLOCKING tab. So it appears that it worked but when I run the PC PITSTOP test which tests 2D performance along with many other things I get a very low score in the 2D test. Like it is still throttling. Before throttling I would get 600 points now with the throttling I get 100 Points? Did I do something wrong with the flash or did this not cure the throttling issue?

Unlikley if you dont change the 11625Mhz.

Yeah thats like how it is, with 1.5 the textboxes show you the values from the hexview where they think the memory speed is.
If they are pointing at the wrong position you see wrong values.
If you dont change the wrong values there should happen nothing, your BIOS is saved exactly as seen in the Hexview.

But could i see your BIOS plz which shows not correct? :)

Hi, i only heard bad things about nvflash 5x with 6800s, nvflash4.41 or 4.42 is said to be working much better.
To check if you have throttling, try rivatuner. It monitors your clockspeed, you can see if the speed drops during a game or in windows etc.

[BlackHawk2383]

The only nvflash version i could get to work with my 6800 Ultra was 4.42. My card is much more stable now but still wont oc past 440 without very random doom 3 reboots.

I don't see an option in RivaTuner for monitoring clock speed? What is it under?

[xtremetheme]

Main Tab -> Target Adapter Section -> Customize -> Hardware monitoring

[Section8]

Thanks extreme you have been a great help. Everyone here at this forum is great. How do I get it to minimize so that I can view it while playing a game? I DL'd NVFLASH 4.42 on your recommendation and it works perfectly for flashing my 6800 Ultra. The 5.08 was a nightmare but the 4.42 was flawless. Thanks again.

Wow I figured it out and the Riva Tuner fix seems to be defeating the throttling. Right now my temeratures are 15C and my clock speeds are 500/1250 according to the RivaTuner hardware monitor. So that means that the EnablePerfLevelForcing 1 did the trick. Otherwise it would be throttling down right? WoooHooo I am a happy man.......Thanks guys.

[aoc007]

Does anyone know how to get low level overclocking working in rivatuner? Im using forceware 61.77 and it says its not officially supported, I guess thats why the low level ocing part is unavailable. Is there a registry tweak to force it to be enabled? Id really like to see if low level will get me higher clocks.

You dont need to minimize it just start the game with it visible and then alt-tab, should work fine depending on the game.
Strange that you had problems with 5.08, I havnt.

[blass]

what would you do in low level overcloking that will alow you higher clocks??

[aoc007]

Ive read that it usually clocks higher than driver level overclocking.

what happens if we set the throttle to 1.5v? :rolleyes:

If you have good cooling set all the voltages to 1.5 volts. I think when it throttles it really throttles to the 2D setting so make them all the same to be sure. My throttling was 100% cured with the RivaTuner fix.

I love them. I have not really tested them to there fullest yet though. Still trying to get the most out of the GFX card. One project at a time for me.


OK after some testing I have come up with some more information. If you read some of my earlier posts you read that I have tried many things to get around the Throttling issue and I thought it was the RivaTuner but now I am not sure? I disabled the PerfLevelForcing rebooted then clocked my gfx card up to 502/1300. I then opened the Nvidia control panel to see my temps which are at 15C right now so throttling should occur. I then clocked up the Video Card to 502/1300 and opened RivaTuners Hardware monitor. I was expecting to see the clock speeds at 475/1200 which is what I had flashed the BIOS to and expected it to be there because the card should be throttling at 15C. It was still running at 502/1300? So my best guess is that flashing the BIOS was the cure for the throttling? When I flashed my BIOS I changed the 3D, 2D and Throttle voltage all to 1.5 volts. I also changed the clock speeds for both 3D and 2D to be 475/1200. I am assuming that the throttling must be totally controlled by the voltage settings?

[Funbags]

I dont trust that riva monitor.. cause i noticed some wacky results with it. Like it would stick on the 3d Speed then randomly do down to 2d clock speed.. I dunno...

What bios did you just flash?

Hi, the 2D Speed will be corrected in next version. Editing the Voltage and 3D Speed will work as long as you dont edit the 2D ones.

What happens when you edit the 2D voltage and core/memmory speeds in 2D? I did both 3D and 2D on my Ultra and evrything is working fine.

[bmg]

The newer bios's no longer seem to have separate entries for 2d and 3d, since the bios now sets them the same. There's now only one set of core/mem numbers in the bios to change.

For those who where looking for the newest nVidia BIOS Editor they can get a copy here :
nVidia BIOS Editor (http://www.mvktech.net/index.php?option=com_remository&func=fileinfo&filecatid=425)

What is new? (http://www.mvktech.net/content/view/53/38)
Changes in this Version
- Changed name from 'OmniExtremeEdit FX' to 'NiBiTor' (nVidia BIOS Editor) name is much shorter and makes more sense...
- Fixed BFG6800U 2D Speeds
- Fixed 5900XT Timing A
- 5900 Class: Memory Speed will be set the same in all modes, to avoid possible conflicts with Beta ForceWare Drivers
- Added Option to edit memory speed table entries for problematic 5700 BIOSes
- Fixed new versions link

Enjoy :-)
