Why dont you save the BIOS as ROM's, how can i convert it to a ROM? DO i just open fermibioseditor and save as .rom?

Sorry for the the thread necro, but I have a question regarding the "unlocked" over-voltage BIOS provided at the beginning of the thread.

I have a GTX470 and wanted to flash a bios that would allow me to use more voltage...found this thread.

However, when I examine the "unlocked" over-voltage bios with Nibitor the INTEGRITY is displayed as "yellow" instead of "green," which in most guides for bios flashing state is necessary for a safe flash. Also, when I used NVFlash to compare the bios with the card it states the it doesn't match showing the ID # ending in a 2 instead of a 0. (From what I have read this is simply the difference between the gtx470 and the gtx480).

Has anyone used these either of these bios first hand and had success? I want to try this, but don't have a back up card atm and not sure how comfortable I feel doing a blind flash.

Thanks for your time.

if you dont have a backup dont do it. you can always use a spare rig like a parents or brothers. the bios did work when i used them about a year ago so....

Yep, if you don't have a backup card, don't flash any BIOS. If anything goes wrong while flashing (power flicker/surge, accidentally unplugged) you'll have no way of recovering your card.
If your GTX470 isn't reference, that BIOS will probably brick it. Once you have a second card for recovery, your best bet will be to backup your BIOS with GPUZ, make a copy, use NiBiTor to mod the copy BIOS' voltage limit, then flash the modded copy. This way, you have:
A.) An exact replica of your original BIOS incase something goes wrong
B.) Your over voltage BIOS is your BIOS, so it's less likely to go wrong if you have a non-reference card.
It cannot be overstated how important it is to have a backup card or integrated graphics in case the flash goes bad.

Decided to go with modding a version of my cards current bios, which from what I have read is a much safer way to go (as you pointed out).

Worked flawlessly, was able to get:

800/1600/1850 @ 1.125 mV with temps @ about 93C for about 5 minutes.

Now I just need a better cooling solution than stock air.

Thanks!

yellow is fine, it removes OCP protection which causes a false checksum(last two bytes of BIOS)

Nice! Upping the memory clock can give some stellar performance gains, too. Just be careful how high you go.
GTX470/480's are kinda the unloved children of the aftermarket air cooler world. The Gelid Icy Vision and the Zalmann are about the only 2 I can think of. If you water cool, that's a different story. biggrin.gif

is there any posibility to underclock my gtx470 SOC under 405mhz with msi afterburner, it won"t allow me go under that, i allready set enable unoficcial overclocking to 1
post #890 of 926
athlon, you might have to edit the BIOS to do that (assuming you're talking about the idle clocks).
