Util to edit the 6800 bios's?

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

Hmm Cybercat could you try if giving Thtrl. more Vs helps you oc?
Maybe its the same like with the 6800GTs.

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.

can be... tnx alot for yuor job

do you think is possible to leave the fun spipping at the max all the time?

Sorry what u mean with fun snipping?

And i have Version 1.2 ready.
Fixed 6800GT clockrates and voltages, fixed some 6800NU and 6800U clockrates.

top job mate,
version 1.2 works perfect.
thanks.

I had both the 3D voltage and the thtrl at 1.5v when I did the mod. 2D was at 1.2v.

When pc start the fan run faster,when bot on windos stop and run medium,Im askin if is possible to leave the fun spin at the max all the time.

[warhorse]

i think he means is it possible to get the FAN SPINNING at full speed all the time.

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.

Hmm that BIOS looks strange, the checksum is either missing or incorrect, you sure it was read out correctly?

I will ask to make sure :-)

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 )

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 , 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?

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.

I am not sure what V mode the 6800 in 3D uses, but its easy to test:
