Is this voltage locked? I can freely move the voltage slider in afterburner , but it doesnt actually apply the changes.

I have used the same card. The only successful way I found to change voltage is with Trixx 4.4b. Nothing else effects voltage. Pretty sure others on these forums will suggest the same thing. I was very frustrated, but trixx 4.4b came through for me.


edit: No other version of trixx has worked, and 4.6 seems to give problems.If its the blue pcb, AB doesn't work, even using the unofficial unlock method is useless.

The card is piece of crap. I swapped it for an Asus 670 because of getting 2 Free Games with it. I thought I was getting a Better card. It has a default voltage of 1.256v and yet struggles at 1100. To achieve this, it sounds like a hair dryer. I mean with 1100mhz, I am getting under 10k 3dmark11 score. My 670 got over 10k. I thought a 7970 is the faster card. I just want my Asus back.

I think you just got a dud as far as overclocking goes. Most 7900 cards can easily hit 1150 on the core.

Sounds like a total dud.


What is the ASIC score?


My HD7950 tops out around 1375mhz on the core for 3dmark11 benchmarks on water with ASIC score of 89%

Which card did you get as there's a lot of 7970s and brands. If it's ASUS that would probably explain the problem. As far as I know most use MSI, HIS, Gigabyte, and Sapphire (there may be more but these are key players). Most 7950 and 7970 do at least 1150 without an issue.

you got dud, as tiny tom logan always says picking a card is like a silicon lottery.
even my sapphire can get past 1150

anyway i thought the sapphire 7970 has a high stock voltage due to the fact it has its voltage locked

So i just got my msi twin frozr 3 7950 the other day, 6+6pin so no 7970 pcd im guessing. So where do i go from here?

Through msi afterburner i did a quick boost up to 1100mhz from 960mhz and changed the memory to 1350mhz from 1250mhz, and im running the 13.2 beta 5.

Ive read and heard about changing bios, but i dont know which and what and even why.

Thanks yall.

stick to manual voltage tweaking. don't change BIOS. 1100 mhz is a decent overclock. monitor your core and vrm temps under load using gpu-z or hwinfo32 . core temps below 70c and vrm temps below 90c should be your goal. see if you can get it upto 1200 mhz at stock voltage and if required tweak voltage. keep temps in the safe range with a custom fan profile in msi ab or sapphire trixx (whichever you are using for OC).

My 7950 has ridiculous vDroop in demanding games -- nearly 90mV in Far Cry 3. I'm shocked that my GPU manages to stay stable at 1150/1500 with vActual around 1.010V, but is such a large drop normal?
