Re: [ANN][X11] X11 (Darkcoin etc) miner (based on sph-sgminer)

Try fiddling with worksize, i.e reducing it.

Tried 32, 48, 64, 96, 128, 192. The best result was 2.74 MH/s at --worksize 64.

i have same problem by my 290, it seems that improvement is not support for 290s cards

best i can get is 2.9mhs

Sounds weird and took me a while, but many GPU threads seem to work well on 290s with this kernel.
This is what I run now on 290 TRI Xs under PIMP, gives me about 3,4 MH.
It crashes sometimes on startup, but once it runs its rather stable.

There seems to be a limit of 10 threads in sgminer, wouldn't it sound legit to have 11 threads then?

Thanks for the tip, which version are you running, the one compiled by RRT5ON? Also what clocks do you have set on your 290 Tri-x? And finally which drivers please Cheesy

Its Catalyst 13.25.5 and PIMP/Debian 3.12.9-1
I compiled it right on the rig. Clockspeed is 1055 more or less. I have a batch of cards which makes it only to 1025 though.
