No, I meant the value of -h. I didnt find a solution to this problem.
Ahh, no worries, I misunderstood you there.
I tried playing with the -h settings, where -h = 1152 (default), I get:
GPU #0 algorithm ASM, -h 1152, -dmem 1 (Memory used: 4722MB)
GPU #1 algorithm ASM, -h 1152, -dmem 1 (Memory used: 4722MB)
XMR - Total Speed: 1734 H/s, Total Shares: 1, Rejected: 0, Time: 00:00
XMR: GPU0 865 H/s, GPU1 869 H/s
If I try to get claymore to use more memory, then the hash rate slows down:
GPU #0 algorithm ASM, -h 1925, -dmem 1 (Memory used: 7892MB)
GPU #1 algorithm ASM, -h 1925, -dmem 1 (Memory used: 7892MB)
XMR - Total Speed: 1697 H/s, Total Shares: 3, Rejected: 0, Time: 00:01
XMR: GPU0 847 H/s, GPU1 850 H/s
How would you work out this "sweet spot", I think I need to do some more reading on the OP...
