So ive tried everything in the book, from a lower mem clock to engine clock, to around the 1.57~1.6 ratio, multiple threads, single thread, higher & lower intensity, I even tried a modded bios, you name it ive tried it.

interestingly increasing the memory speed doesnt increase kh/s at all. stock is 1250mhz and ive taken it to 1500mhz....... 0kh/s difference

My best and final settings for the 7950:
core 1140mhz @1.125v
mem 1250mhz
intensity 20
single thread
TC of 44500

Im getting around the 590~600khs in cgminer, 2 independent mining pools say im getting between 650~750khs. Im not certain what one to believe.

Now Ill have to see if I can squeeze anymore from my 7970..............................
