Util to edit the 6800 bios's?

[WeStSiDePLaYa]

any chance on seeing vmem voltage on this soon?

[martinakerman]

1) Can i flash a 6800U bios from a CD in stead of a floppy?
i mean, i use a start up cd, DOS and i got nflash and the new bios in a cd and run it from cd...i think its the same isnt it?
2) i need to flash to 450-1200 1.5v what bios should i use to mod on ? any? some rev.? like .15 or something?
3) do i have to set 2d and 3d at the same speed?
4) in 2d is it not recommended to increase to 1.3v ? (core 450mhz)
5) Has Fast Write to be disable? my Mb is an Abit Ic7-g has no FW option, is enough from Coolbits2?
6) there are people that cant flash to E-vga 6800 ultra extreme edition original, (450/1200 3d) (400/1100 2d) they get ID Mistach, even using all commands.

7) does sombody tired overclcoking from bios and/or soft (from windows) i mean...
core default 400 and rising from win.Soft.(coolbits) to max speed reached, and tried same speed from bios, and see if you got same results?
8) be carefull if u wanna by a 6800 ultra, there are a LOT of vendors like ASUS, ALBATRON, LEADTEK, GAINWORD etc that in some cards are using 2.0ns memories on Ultra´s in stead of 1.6ns (600mhz)
9)Thankz

And
10) Whay using the Nvidia bios editor, 1.5 or 1.6 etc.
Once you mod the Vcore, if you edit again the bios you cant see some voltage again?
Example... original bios u see 1.1,1.3,1.4,1.5 v i set 1.5..Close program, open, edit the modded bios and now i see 1.1,1.3,1.5 v.

I have the same problem.

It is no problem at all to boot from a cd.
Just find a DOS-bootable cd on the Internet, boot up and type:
C:
CD \BIOS
nvflash -f mybios.rom

Works like a charm. Or something :S

Well...

xtremetheme, your biostool is great... I have a feature request. I think the 6800 cards has an operating range of 25C - 125C. To be able to change this would be awesome. I think Gainward has solved this problem though, cause they're selling waterchilled 6800Ultras and I suppose they start.

With my watercooling, the core does not reach 25C. ( It's cold where I live in Norway). Room temperature is ~ 20C. The problem is, the card woun't start with such a low temperature and when the graphicscard doesn't start, the computer doesn't.

[disco_bazoon]

How much voltage does GT cards like? I mean, with proper cooling 1.5v should be okay, right?

@Mental, hey fellow Norwegian

[Mental]

Hello disco_bazoon

The GT handle 1.5V just fine (would've handled 1.6 and 1.7V just fine too with proper cooling). My 6800GT with a reference ALU-heatsink did handle 1.4V. (1.3V standard) Had an increase of about 4C (to 90C :S) while running 3Dmark. Though I've never tested 1.5V I think you'd better use a better cooler than the standard reference for this.

@Mental, hey fellow Norwegian

With proper cooling 1.8v would be okay

[disco_bazoon]

I tried some today, but I got a message saying "could not open I/O device mod.bin" or something like that. Why's that happening? :S
Oh, and I used the commad: nvflash -p -u -f mod.bin on nvflash 4.42.

[disco_bazoon]

lol, okay, I sorted it. I wrote "file.bin", instead of "file.rom". I'm too used to mobo bioses

[disco_bazoon]

Hhmm... is anyone here having problems with 3dmark 01 after the bios flash?
I flashed mine to 1.4v, and everything seemed excellent. I gained over 20MHz on the core, from 410 to 430. 3dmark 05 ran fine, same with 03, but whern the turn came to 01, it just instantly locked up. Okay, so I lowered the clocks, but still the same thing.
I lower more and more, but it still the same thing. So, after alot of trying, I have come to the conclusion that I can't keep both core and memory overclocked at the same when running 01. If only one of them are clocked at the time, it runs fine. But as soon as I clock both of them it freezes. Really, really weird! Tried with 4 sets of drivers, and about everything I can think of. Everything else I've tried is fine, including: 3Dmark 05 and 03, Far Cry, Doom 3, Call of Duty UO.
Any ideas? :/

Disco is a freind of mine.. and I just flashed too .. Having the same problems also.. Dam 3dmark01.. !!

[xgman]

01 is yesterdays technoloy. Just move on.

lol.. Oh great thanks for the help ..

Well, actually I like to use it for a test of system stability.. most of the new ones are more video card dependent.. Yes I know there are other tests but i was wondering why it was only doing it with that.. I guess more of a curiousity thing too..

O-well.. nm..

When I try to flash with 5.08 or 4.21 even, I get "PCI subsystem mismatch" 10DE.0000 IS rom AND 10DE.0205 is CHIP. I am trying to flash a PNY 6800U to get higher voltages and used the Nvidai n345.rom as a starting point and tthen saved the new voltages through omnifxbios program. Any ideas what went wrong? Thanks.

edit: the evgabios posted earlier here seemed to flash ok, but the 3d/2d overclock settings I saved in omnibios didn't seem to stick in the Nvida control panel (driver ver 66.81)

Like many others I want to thank Extreme theme for his great program, I now have my BFG 6800 Ultra running at 475/1230 Mhz which although not amazing is a nice boost

Thanks again.

[duKe]

mh, one question. i wanted to edit the bios of my msi 6800nu with omniextreme.

but when i open the bios it looks like this:


does this mean that the voltage is already set to 1.4V?

[duKe]

anyone?

[aoc007]

Yes, unless theres an error and I doubt it, its at 1.4.

[duKe]

i have downloaded 6800nu bioses from asus, msi and bfg from mvktech and they all show 1.4V in 3d. so i guess thats right.

[aoc007]

that seems weird that it would use more voltage than the GT, try pming xtremetheme it might be a omniextreme error.

[dr_sharp]

I registered on this forum to thank everyone that has contributed to this thread... especially extremetheme and mavke. I'll be flashing (GT->moddedGT@U) next week and though i've never flashed anything before the info in this thread is more than enough to cover the entire process (including modding).

btw Mavke... wonderful site. Thanks again.

@Xtremetheme:
What's about timings? Will you ever release a new Version of your tool, that allows to edit the 6800-timings? It's proofen, that a card with GT-bios perfoms better, than one with Ultra-bios at the same clock-settings. It must be because of faster Timings on a GT-bios. But you eventually can clock higher with a Ultra-bios.
So what's about comparing a GT Bios with an Ultra-Bios to find out where the timings are stored and add a possibility to edit them to your tool?

According to Unwinder (Rivatuner maker) over at the guru3d forums it may be possible to mod the 6800LE/NU/GT/U bios into ignoring the hardware pipeline bridges at the back of the card so that all/selective pipelines are enabled by default without having Rivatuner installed: http://forums.guru3d.com/showthread.php?threadid=110067

Would you be able to add a feature like this into your editor, as well as adding an option for the user to alter the GPU temp shutdown temperature value?

Unwinder talked about adding a script to allow this (after user identified the working pipelines and VP), maybe you can work with Unwinder to allow the exported data from the next version of Rinvatuner imported into your bios editor for modding to unlock the chosen pipelines/VP by default.

[stealthbomber]

The script is here and it works! ^^^
