2 months ago it was 19MH/s but now same VGA card, same .bat file, same core/clock, same Windows version, same VGA driver, same Ethminer 0.9.41, same everything but i can only get 17.4MH/s. It's quite strange and i can not understand why. Could some one please tell me why? Thanks a lot!
Card: 7950
Core/clock: 800/1000
Driver: Crimson 15.11
OS: Win7 x64 (fresh reinstall)
Etheminer: 0.9.41
Bat file: "ethminer.exe -G -F
http://xxxxxx.xxxxxxxxxx"
Speed: 17.4 MH/s
P/s: I've tried "--cl-global-work 16384" and got 18MH/s, but i didn't put this parameter to the bat file 2 months ago so we can ignore this.
