Hello

I use multiple setups for the R9 290 cards but the only difference in the intensity and hash rate. Here is my data.

–scrypt -o [pool url] -u [worker] -p [pass] --gpu-platform 0 -d 0 -w 512 -v 1 -g 1 -l 1 --thread-concurrency 24550

Then:

-I 12 =250 kh/s I use this when I am running 3d using games with cgminer in the background
-I 14 =600 kh/s I use this as my normal whenever the computer is actually in use. Like right now.
-I 20 =850 kh/s This is for when the computer is idle and doing nothing but mining.

Note that I use the default memory and gpu speeds, but using the newest AMD driver I set the power to 20 and the max fan speed to 80%.

Hope this helps
