Congrats! is that the PCI-e version you're talking about? if so, could you send me the bios file please?Quote:

Can anyone help me mod this card?
Is the BIOS I have relatively close to other 6800 BIOS's mentioned in this thread? Can this BIOS be altered to increase my voltage and fix the 25C temp problem I get when I use my water chilling system? What about a hardware mod?
I need your help!

Hello,
I want to backup my BIOS card with nvflash but I have the message "PCI bios not present
note : this program can only be run under DOS"
I typed nvflash -b origine.rom in MS-DOS mode (under Windows XP then in safe mode). And I tried other commands like nvflash -c (check)...and it does not work too. It seems that nv flash does not work with my BIOS card.
I tried nvflash 4.42, 4.46, 5.13 with the same result.
On the other hand, I managed to backup the BIOS with Xbios Editor. But that does not solve completely my problem since I cannot flash the bios. And OmniExtremeEdit FX 1.5 does not find any information when BIOS is loaded.
So, would you know how to make nvflash work ? Or what other tool could I use ?
My card is a Gainward 2600 Ultra Golden Sample and the present BIOS version is 5.40.02.15.06.
In MVtech site, I found the same BIOS version. I explored it with an hexadecimal editor and I do not find 2D and 3D voltages and frequencies. I have read that GPU 3D voltage is located int E683 address, 3D GPU frequency is at E56E address and DDR3 frquency is E573 address.
So, would someone know where to modify the 2D and 3D voltages/frequencies in 5.40.02.15.06 Gainward bios ?
Thanks for your answers.
overclock,
You need to flash from a DOS bootable floppy.
Read this: http://www.mvktech.net/content/view/15/37/
As for the voltage questions I don't know, I'm a newbie at this so I need help myself... :D
Thank you, nvflash works now. It did not work because I used it either in MS-DOS in Windows Xp or in saffe mode, but not with a bootable floppy.
But, all advice concerning the gainward Bios mod is welcome.
Would you know how to protect oneself in case of accident when flashing ? I have read using a PCI card or using a bootable floppy disk with autoexec.bat containing nvflash -f -5 -6 backup.rom, which loads automatically your original bios file if the card does not work anymore. Would you have tested it ?
Thanks.
I dont really want to search this whole thread so can somone point me to the best BFG 6800 Ultra OC bios? Is there any bios's for this card with the GT mem timings but still an ultra bios? thanks!
Hello Tony,
You can visit http://www.mvktech.net/index.php?opt...er&filecatid=4
You will find many Nvidia bios but I don't know which is the best for BFG 6800 Ultra.
too many bios's... id rather use one that somone has gotten thier best results with...
I can mod a bios for u, but I dont know how to do the mem timings/ or if it will be safe at those timings. Just post what u want me to do and the make of the card.
its a bfg 6800 Ultra OC which is the reference nvidia 6800 ultra. I use GT bios's for the timings and no 2d profile...my only question is which is the best bios for the default nvidia pcb?
My 6800GT only make 375mhz for the core, if I put the bios 1.4vwill be better? where download the bios?
thx guis my english is bad :(
With the 1.3v that a 6800GT is normally set at, I am surprised you only manage 375. Especially since my 6800LE works no bother at 400 with same 1.3v.Quote:

I must warn you however that some 6800GT cards don't like 1.4v on the GPU, so you do it at your own risk !!!!
I've got a BFG 6800 Ultra OC, and while I'd rather do a voltmod for the core, I would like to know if there's any word on whether there's a fix for the temp issue...
I've seen the LN2 w/r on sli'd 6800's and they must have done something with it...
I've got a 507'd Prommie all modded to mount on it, and I'm just plain itchin' to get it on there, but there's not much point if it's just gonna throttle down...
Hey moddolicious, you wouldn't happen to be able to write in a fix to the bios and possibly a driver fix, if required, to make it happen would ya? :hump:

If you mean the higher than normal temp reading in drivers tab, that was bad drivers and is sorted in new oned on nvidia site.
I have a Chaintech 6800 U its 425/1100, not claiming to be 10% o/c
Ive ran it upto 460/1219 on standard bios and then i grabbed a modded bios from a GT as its got tigher ram timmings, even at 425/1100 the difference with the new bios with same volts was 300+ in 3d Mark 2005, then i modded bios to 1,6v but only get 465/1225 with NO artifacts in 3d mark 2005 as im on normal cooling, core never goes by 65C on load but i dont know how hot ram runs.

Nah it's the freeze bug I'm looking to sort out...
I've noticed a few using extreme cooling on their cards, and not having a problem...is that sorted out with new drivers, or is it still a bit hit or miss?
The freezer should run -50ish, so I need to be sure it'll work, and not throttle, at that kind of temp...
Guess I'll just have to get it hooked up and see what happens :)

Hi all
anyone have a good bios for pov 6800U PCI-E
i an h2o cooling my card and i cant get over 475 core and 1150 mem
the card don´t get very hot
Wel if you can provide yoru Original POV 6800U PCIE then we can do some changes so that it will run at better speeds... So backup your BIOS and attach it here so we can check. ;)Quote:

1.5v is only just above the daefualt volts for a Ultra anyhow, i run 1.6v on air and no issues gpu temp on 3d never goes by 65C ever on full load with 465/1230
1.5v is only just above the default volts for a Ultra anyhow, i run 1.6v on air and no issues gpu temp on 3d never goes by 65C ever on full load with 465/1230, i only gained slight increase as i could nearly do this with normal volts, but remove standard cooling pads or grease and us artic silver 5 or ceramic
DEVIL DK, try this bios. I just raised voltages to 1.5v. (stock=1.4)
I tried the pencil vmod from vr-zone I can only get 1.67v or 1.77v (went up and down the between 7.4K~8K ohms) which I think is too much unless you're doing -0c temps. I'll do the 1.5v on the bios, by the way 50c is my load temp. If anyone else has any input please go ahead. Thanks.
Hello Xtreme modders, I need that someone plz mod my original bios to get the max volts out of it, if possible make 2 files one for 1.5v and another with 1.6v.
Right now I'm using a hard mod to get 1.69v, hit the wall at 595 core with DryIce, I need more :D
Card is a Gainward 6800Ultra 430/1200 stock clocks.
Here is the file.
