Util to edit the 6800 bios's?

[Mavke]

And a late mirror of version 1.3 :-)

OmniExtremeEdit FX v1.3 - At mvktech.net

"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

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.
The Prolinks re01 default bios is this one

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 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.

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

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

Also has anyone got a backup of a Bios from a BFG 6800 Ultra with Fast Writes enabled (tried the one from www.mvktech.net), but its that Rom which gives the above error in Nvflash!!

Thanks for the help.

Also it has support for 5800/U, 5700LE, 5600/U/XT, 5500, 5200/U.

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?

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:

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.

Thx, i thought noone would use the Editor with a Quadro, but I will add support.

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 go

if 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

Card: Chaintech SA-FX5700 Ultra 128MB
BIOS: 4.36.20.18.05

[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

*rename to .rom*
