There are several default voltages for 7970's depending on how "good" your chip is. Generally lower stock voltages are better chips (with higher ASIC's) but not always. I have three Sapphire 7970 OC's in my possession right now and one has a stock voltage of 1049mV (ASIC 86.5%) while another has a stock voltage of 1175mV (ASIC 68%)...

Thanks for clearing that up, makes sense since the secondary card has a 83% asic and the primary card has a 68% asic rating.

Alright guys, I've got my 7950 stable at 1100/1435 at 1.1 volts. I would up it, but I'm worried about temps - at 63% fan speed, I'm getting temps at around 75 C. I really don't want to hit the 80's. tongue.gif

Pg1 has list with clocks, voltage ect.


I run my Sapphire HD7950 OC 950mhz Edition at 1300/1600 1.22v.


It can go faster but where I am at right now is a sweet spot for gaming.

those clocks are decent. you should not bother to go higher given your temps.

Looking forward to you hitting 1250 - 1300 Mhz in CF and posting some bad ass scores in games (BF3, Crysis 2, Metro 2033) and benchmarks like unigine heaven. Settle this HD 7970 vs GTX 680 thread debate which has been going on for too long once and for all . thumb.gif

So my card at that speed will be the same as a Ghz edition. No core changes with the Ghz edition?

exactly the same.

I sent my set of cards back to Amazon, because of flickering and artifacting I was getting in games. The new cards are better than the old ones... one is 83ASIC and the other 72ASiC... as opposed to 60 and 67 for my old cards. I was able to get a stable OC of 1224/1780 with these cards. thumb.gif

Now, does anyone know of a fix for AB applying OC'd clocks all the time? I remember something about the profiles, but I can't put the clocks down to what the 2d clocks are normally. Plus I also have the issue with sound cutting out through HDMI/mDP, because of AB. I'm using the latest 12.7 Betas.
