Hi!
I'm only getting 1.24Mh/s on the Sapphire r9-280x, I guess it should be a little more, with my R9-290 I get ~2.5Mh/s.
Thats my current config:
--shaders 2048 -I 23 -g 2 --thread-concurrency 16374 --lookup-gap 2 -w 256 --auto-fan --gpu-fan 80-100 --gpu-powertune 2 --gpu-engine 1100 --gpu-memclock 1250
any suggestions how to tweak this?
Theses are your 290 settings?
Your 290 is stable at 2.5, even after an hour of mining?
No, this are my current settings for the r9-280x.
Thats my settings for the 290:
--no-submit-stale -I 22 -g 1 --thread-concurrency 16000 --lookup-gap 0 -w 256 --auto-fan --gpu-fan 80-100 --gpu-powertune 2 --gpu-engine 1000 --gpu-memclock 1500
EDIT: Okey, I got 2.421Mh/s avg.
Yes seems to work stable, but I it only runs now ~ 2h.
