What's the best mining program out there?
Currently i'm running guiminer scrypt 0.5 (win32) on windows 8.1 64, i could not find cgminer 3.7.2 or whatever version is best for scrypt mining.
I'm getting between 650 and 690 khs per card under "280x" settings in guiminer and no overclocking or undervolting.
I've tried overclocking with the trixx utility but i get blank screens when i change the memory speed. Even when i keep everything stock and let it run at night it'll crash, but it does not look like it, because the fans are blowing hard but no heat, the row of lights on the back of the cards are not doing much.
