Robin B said:My Pov GT is stabel at 400/1100 1,3v but with 1,4v the card will hardlock on me. Anyone who knows why ?? Temps are max 83c.
Optimummind said:It's probably the high temp on the GPU or the lack of clean power to the GPU. If you have any other components overclocked such as the CPU, try downclocking a bit and give the GPU another shot at overclocking.
the_village_treky said:do you all think that the leadtek cooler(the big assed coper one) would be good enough to flash? im fairly shure that leadtek uses the EXACT same cooler on their ultras, but maby the bios runs the fan faster(i think i heard that they do this somewhare). anywhay, would it be alight if i used the leadtek flashing utill?
This works fine for saving my BIOS, but for some reason I get an error when I try to flash the modified file. I am a DOS retard, but I followed your instructions to the letter.Optimummind said:(3) I put the above 2 files in the same directory of my choice.
(4) Start-->Run-->cmd
(5) Browse to the folder that contains the flash tool and the BIOS rom.
(6) Typed this command in to backup my card's original BIOS:
nvflash442 -b mybios.rom
(The "mybios.rom" portion is arbitrary. You can name the BIOS to whatever you want.)
(7) With my BIOS backed up, I proceeded to flash to the new Ultra BIOS. I typed:
nvflash442 -p -u -2 ultra.rom
(The "ultra.rom" portion of the code is also arbitrary. Whatever the Ultra BIOS name happens to be, you'll be typing in that name.)
Big Lar said:Nice.. I have the same ramsinks on my EVGA, and have had it to 450/1150, but have Not tried the memory higher. Again, Nice looking setup, I have the swiftech blocks and they seem much "bulkier" than the streamlined look you have.
Optimummind said:EDIT: Instead of using the Leadtek BIOS, I am now making my own custom BIOS files based on my BFG GT's rom. Here is the link to a page where all my BIOS creations are stored (about 23 dif kinds). Thx goes to [H]ard member Zok for hosting these!!
Godmachine said:...BFG doesn't Honor the warrenty on a user overclock ..only a BFG overclock and yes there is a way for them to tell. The card records( i believe its stock in the BIOS) the current clock every 10 secs i believe then erases the last speed after it records a new one so if your card dies and you think they won't know guess again.

I(illa Bee said:how safe is it to flash form the command prompt in windows? I allways boot to dos 6.22....
patriot71 said:I get this message every time I try to flash....
nvflash442 is not recognized as an internal or external command, operable program or batch file.
whats the deal?
peacetilence said:Sorry I don't have the time to read through this whole thread but I'd like to ask if it's possible to edit the voltage in the bios I have right now without flashing a new one? I don't have a floppy drive on this machine.
peacetilence said:Another thing I'd like to ask is, will this volt mod help with artifacts at all? Right now if I clock my gpu to 420 I will get artifacts on the turtle in 3Dmark03. Will raising the voltage have any effect on this?
ozziegn said:Optimummind
so is there any real reason why I should flash the BIOS on my GT that already does 420/1100 without flinching?
yes, I know that you're getting 430/1150 but honestly, I wouldnt highly doubt the meager increase in speeds would be worth the effort.
please give me some good reason(s) why I should attempt this other than risking ruining my $400+ video card.
patriot71 said:My mistake, I got it to flash. apparently i dont know how to read the file system...
Before the flash, I couldnt clock any higher than 415/1.13 with my BFG GT OC
After the flash, I am hitting 430/1.17, I backed it down to 425/1.16 to be safe.
thanks for the help
It could be as something as simple as (I'm assuming you're using coolbits) to check the option "apply these settings upon startup." I haven't used nvidia drivers in a long time (got the 9700 pro brand new from crapUSA back in the day) so I was total n00b to that. But, it does work.Edward Ng said:My card is an XFX 6800GT with stock BIOS (for now); it is cooled in my water loop with a Danger Den NV-68 block, and never exceeds 53C, even under overnight load by RTHDRIBL.
I found that it runs 100% stable overnight even with clocks of 430/1170. The thing I found, however, and quite curiously, is that many times when I turn my machine on (after shutting it down, for whatever period, minutes or days), the memory has reset itself back to 1000. WTF is up with that?!? Does anyone else's card do that? This is obnoxious!!!
Anyhow, do you guys think that flashing my card up to higher voltages will fix this? Even if it doesn't, do you think I can get any more speed out of my card? I mean it does pretty damn well as it is, I suppose.
