So I just recently got my 7950 OC Boost edition.
Its stock Core clock was 925 (Boosted from 850). The memory was at 1250.
I wanted more.
I Benchmarked my card in Heaven, and got the following score.
Then I bumped up the voltage to +20%, and boosted the core to 1200Mhz. (Maximum allowed for this card).
No good. Artifacts toward the end of the Benchmark. So I lowered the clock to 1195. Just 5Mhz lower. and Passed. Yay!
New score.
Thats great. But I can do more.
I upped the core clock to 1500Mhz, but I started getting artifacts again. (Oh, no!). I did some tests, and lowered the core clock to 1180. No artifacts anymore, the Benchmark completed without flaw, and these are my final results.
So I took my core from (stock) 850 to 1180, and my memory from 1250 to 1500. And got around 9 FPS increase. My temps never went above 65C.
I for one, see this as sucessful, and highly recommend this card for people that wish to overclock.
Has anyone else had sucess with sapphire OC? or are the other versions actually better? Could I get higher OC with a different version of this card?
