Hi
I have (2) XFX R9 290X GPUs and I consistently get different (seems consistently different) Hash Rates:

Running: Windows 8.1 - 64 bit, CGMiner 3.5 with these settings:

--scrypt   -o stratum+tcp://eu.coinmine.pw:1111 -u UN -p x  --thread-concurrency 28500  -I 20  -w 512 --shaders 2048   --lookup-gap 2  --text-only  --expiry 1 -s 1 --no-submit-stale --queue 0  --gpu-powertune 20  -g 1  --gpu-engine 936


Hash rates I get (pretty consistent):

GPU0 ~ 710 kH/s
GPU1 ~ 860 kH/s


Any suggestions for getting consistent (~860 kH/s) for both GPUs?   Any suggestions for improved Hash Rate?

Thank You
Jim
