First i would like to say that i am new to the forums. I really would like some quick help on this..
so i was really looking for a base voltage/clock speeds for my 7950. i want to overclock my 7950 for better performance in crysis 3. Im using msi afterburner and know how to use it. voltage is already unlocked in the program.

i also have a 750W psu, and an i5 3570k cpu
 
Solution
Well for a base try 1250 voltage and 1125 core clock. turn power limit to +20, and i suggest making a custom fan profile so that your gpu doesnt get too hot. Use a program such as heaven benchmark to test stability, and make sure your gpu never gets over 85C. Since all cards are different you might be able to drop the voltage some and stay stable. As for memory it depends on your card and the vram installed in it. my card has elpida ram so it doesnt overclock well enough for me to try.
hope that helps, and :welcome:

its all subject to the specific card, i was just posting what is stable on my card. if i try 1200 voltage and 1125 core its not stable, so i bumped up the voltage. i am able to bump core to 1137 with 1250voltage, past that its unstable.

gee thanks, i got it for a super cheap price so the fact that i have to bump up the voltage slightly more then most people really doesnt faze me..
