Can't increase voltage - Gigabyte 7970 WindForce 3X GV-R797OC-3GD - Page 11

post #101 of 205
Apparently it does not as somebody in this thread mentioned getting a 7950 instead I believe. That being said I still wouldn't get a Gigabyte card, this 7970 used to be unlocked up to a certain revision as well, no telling if they decide to do the same to new 7950 revision as well. It just seems a safer bet to go with a manufacturer that doesn't do this kind of thing in the first place, or at least one where there are known working methods to unlock it.

Do you know of any manufacturers that have 7950's that are for sure unlocked and reference pcb?
post #103 of 205
Sorry, I do not, I haven't done any research regarding that.

Thanks for all those that tried to help but I too have a 2.1 7970 with same issue. Stuck at 1.175v and bsod after flashing ghz bios file linked here on google docs. I tried flashing both positions with no success as well as running atiman uninstall several times and installing various versions of amd drivers. I am really disappointed!

Would be nice if the reviews would make mention of this issue as it's terribly misleading. I purchased this card thinking I was going to see huge overclocks close to 1300 and I'm unable to hold a stable 1075 on core @ 1.175 frown.gif

Any update on the voltage-workaround for the Giga OC 7970 cards?

It might be worth checking out the Gigabyte HD 7970 Ghz BIOS. 1.1 Ghz out of the box . will allow 1.2 Ghz in AMD CCC.

I tried it as well, it has the same symptoms for me, namely a BSOD with the driver installed. The only GHz BIOS that doesn't do this is the reference AMD version and it actually does increase voltage to 1.256V, but it's not stable under load on my card, even though the card with stock BIOS works well at 1050/1500MHz. I'm starting to think Gigabyte did something on purpose to make their own GHz BIOS not work, I wonder if we should start trying out some GHz BIOS versions from other manufacturers.
