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.

At least yours took a ghz bios! mine just crashes with any of them leaving me stuck @ 1.175v. That said I did find a buyer who is happy to run at that voltage so I'm going to the cheapest 7970 I can find with unlocked volts and just get waterblock to throw in my loop. Would be nice if gigabyte still made windforce's with unlocked v.

I wouldn't take that risk.....

Is your stock bios F40? Also, does your card behaves like this?

Everyone that get's BSOD, when do you get the BSOD? Just when you get in to the OS or before that, like right away at post?

I could just be that your voltage is set too low for the new stock clock wich is 1100Mhz. Default voltage is also higher, so if you have any kind of OC tool installed that applies a default setting on OS start = BSOD

What you could try is setting a default setting with a very low clock, say 900Mhz, and that should take care of that problem if there is such a problem.

Sorry for not replying earlier, for some reason I didn't get any e-mail notifications that there were new posts.

Yes, that's exactly what it behaves like. Stock BIOS seems to be F60.

I'm getting BSODs while Windows is loading, when you see the animated Windows logo. I don't think the voltage is too low, I tried 1100MHz with the stock BIOS and while the card is not stable under heavy load it's definitely stable enough to use in Windows or even in a quick benchmark.

If anyone is interested and willing to roll the dice, I just bought a 7970 from NCIX over the black Friday weekend for $389 and after worrying because I found threads like this saying it was junk for OC I got it and its a Rev 1.0 and as far as I can figure from my research should OC just fine. I am still waiting on my case to arrive before I can build and then be sure it OC but judging from what I know I lucked out and who knows there might me more Rev.1.0 still in stock.
post #117 of 205
Gigabyte has locked voltage control on their OC 7970 cards (rev2.0 and above) but other AIB partners didn't do that (I think).
I've heard/seen people with rev 2.1 non-Gigabyte cards being able to oc/change voltage/use other BIOS with no issues.

I have a GV-R797OC-3GD and I've tried to overvolt GPU/VRAM to the max AB will allow 1.3v/1.7v, but I'm not sure if it is working. Depeding on what monitoring program I use, I get different readings. Gigabyte's OC Guru reports 1.170v/-, CPUID HWMonitor 1.17v/-, Afterburner 1.3v/1.7v, and GPU-Z 1.25v/1.68v. I can hit 1200/1650 for a short time, but only 1125/1450 runs stable 24/7. However, 1125/1450 runs stable on stock voltage as well, which makes me question, which of those voltage readings is the right one?

1125/1450 @stock HWMonitor/GPU-Z/AB


1200/1650 @1.3v/1.7v HWMonitor/GPU-Z/AB


1200/1650 @1.3v/1.7v OCGuru/GPU-Z/AB

Hey guys!
I am new to this forum, and I went through all this thread, trying to search how to make it actually happen, because the second post didn't work for me.
Does anyone know how to do this on 12\12\12? biggrin.gif:D
Thanks in advance to anyone that helps.

Read the last few pages, some people have had luck with the Gigabyte GHz Edition BIOS.
