All right, I finally managed to discover what was the problem. (gigabyte r9 280x)
After disabling
export GPU_MAX_ALLOC_PERCENT=100
I am able to set - g 2 parameter. However now when intensity 13 is set, I'm getting HW errors. The highest usable intensity is 12, but still can't squeeze more then about 300 kH/s : |
export GPU_MAX_ALLOC_PERCENT=200
doesn't work.
(Ubuntu 13.10, vertminer 0.5.3, AMD linux beta driver 14.1, AMD-SDK 2.9)
Any ideas what might be wrong? With - g 2 set, I've got nice 350-370 kH/s but definitely too much HW errors.
Have you any experience with 13.12 AMD drivers? Are they better regarding mining vertcoin than the beta ones?
AFAKI, 14.1 doesn't work well with anything. My 4x280 rig is on 13.11beta9, which I think it is quite decent.
BTW, try to set your tc to 8191 if 8192 doesn't work (8192 didn't work for me). GPU1 is the IGPU, so it was disabled.
