Re: Low hashrate on 7970 scrypt? Under 700Kh/s? Here's what to do...
For the record, I used the bios mentioned in this quote, and my XFX 7970 DD performance went from a high of single thread 550 (I could never get >400 using 2 GPU threads) to 690 (690 using stock mem/cpu settings, but 2 GPU threads). This is the best thread ever, and I'll be sending some donations out for sure. Can't wait to tweak mem/cpu later tonight and break 700!
Congrats! it is a good feeling isnt it? I ended up with 1100/1500, -g 2, -I 13 and TC 8192 even though it defaulted at 22400. Not much else is needed unless your running them in the case. If they are still in a case you may want try 1040thru1070/1475 so it does not get as hot.
