Util to edit the 6800 bios's?

[Çhrist0ph]

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

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.

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.

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?

I dont know how to check FastWrites.
But my Editor should show the BIOS Version.

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! 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

Xtremetheme!

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

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...Edit_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 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?

THX!

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! THX! I'm gonna try to falsh the new bios and report back!

[Desmondo]

Xtremetheme you did it!

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

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!"....

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....

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.
