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

post #21 of 205
Thread Starter 
Just including a screen shot of what I think are the correct dll's copied to the syswow64 and afterburner folder:

but haven't been able to get the voltage to work with 12.8 catalyst and 2.2.3 afterburner, wondering if gigabyte took away the ability to change the voltage in the latest version.

Anyone buy a card lately with the F40 bios and were able to overclock it?

OP - I just received my Gigabyte 7970 OC and it seems I'm having the same problem as you. The voltage is locked it seems mad.gif. We're out of luck and I may be returning this card

give a try with sapphire trixx . if your card overclocks well with trixx it might not be worth the hassle to return and get another brand card. if it doesn't return it.

I have tried a number of methods that includes flashing the bios with an earlier version from Gigabyte. Out of frustration I even tried flashing to the GHz Edition bios which to my surprise worked and increased the voltage to 1.25X (According to Trixx and GPU-Z) but overclocking the card is unstable past 1125MHz on the core. Strange... considering the supposed increased voltage but the GHz Edition bios and card altogether may have been unstable as I didn't take much time to do further stability testing. I didn't bother overclocking the memory which was at 1500MHz with the GHz Edition bios.

The earlier bios from Gigabyte flashed and worked just fine but voltage remained locked at 1.175. I have also tried Sapphire trixx, Asus GPU Tweak, MSI Afterburner and a number of different versions of each but to no avail. The voltage is locked and requires tweaking outside the realm of editing or changing the bios. I am pretty disappointed as I am a strong supporter of Gigabyte products and AMD cards. This would be my second 7970 dud axesmiley.png

Can you share the updated bios from you card with me. My New Gigabytes flash ok but BSOD on windows startup . Tried 12.7 beta and 12.8

Sorry guys for not updating sooner, but the week before last I returned this card.

I am totally convinced that gigabyte changed this card so that u can not change voltage, they have no intention of helping you to change voltage as I contacted their gpu department.

If you intend to volt this card, I would obv suggest you get another model. If you don't intend to volt, then the card is best suited to the tropics where the fantastic cooler might actually be useful.

I shipped the card out yesterday and picked up a Gigabyte 7950 at Microcenter. I've had nothing but bad luck with overclocking 7970s. I have to say, though, that I am highly impressed with the 7950 specifically the Gigabyte 7950.

Pretty much spanks the 7970 lemons that I have owned specool.gif

It would be useful if you post your experience in HD 7900 users thread. What clocks are you running the HD 7950 at . how much extra voltage did you need ? also can you post temps, both GPU and VRM. and is your card got any more OC headroom ? and what fan speeds are you running and how is the fan noise. thanks in advance. thumb.gif

1250MHz core, 1550MHz memory, 1.262 volts, fans manually cranked to 50%. Have run numerous instances of Heaven and 3DMark 11 all night and played some BF3 and League of Legends this morning. It is stable thus far and temperatures don't exceed 67 degree Celsius (Monitored in MSI AB). I am 100% sure this card can be pushed further. Here is another 3DMark11 run with GPU-Z for verification thumb.gif



Impressive for a $300 card eh? tongue.gif
