my wu is also around 101%..just optimized today from aprox 85%
and i need to mention that for a last 2h i have 0% of rejected shares
How did you optimize that ? My WU is about 90% after 5 days of mining on all my rigs, and they all have different settings as they have different cards. 280x are with 13 intensity but they still have 90% WU, 290's are with 20 intensity and high thread concurrency and have again the same WU ( 90% of the hashrate ). So even after a very long period of time ( 5+ days each rig is running with no disconnects or power loss ) i can no get more then 90% WU, in the same time it seems it is pretty much stable around that number for all rigs i have.
i've 3x 280x what i've done
my cards was undervolt..so i rised on 1100-1163v
second thing, i put gpu-engine 1020-1060,1020-1060,1020-1060 (from stock clock until 1060 for each card)
tird i had mem clock at 1250, i've put back to 1500,1500,1500
and last thing thread concurrency on 8192,8192,8192
intesity is on 13 and i testing powertune but there is no difference, 20 or -20 same thing...i didnt see any changes
