I checked it with mem 0 or +500, but nothing changed! which number do you prefer?
Also I checked my driver version : 382:33
Did you add 16 gig or more virtual memory? Run without oc first, then increase the clock slowly.
I have 8GB of ram and 16 (min) to 32(max) VM.
How much will take to mine at least 1 SPR (seeing any result in spreadcoin wallet) at this time with this difficulty and 75 mh/s (3x1080+3x 1080ti)?
(because after some hours my balance is zero)
