For the 6850* and 5830** (same overclocking settings) my hashrates are 1050 and 958 respectively with sph-sgminer 4.1 (so you may want to add it).

If you are collecting CPU data, I think we can add info for that too.


* --kernel darkcoin -I 18
** --kernel darkcoin -I 17 --shaders 1120 --thread-concurrency 14

Hey there...
Using a Sapphire HD6970 2GB

Getting around 1.470 -1.520 MH/s with SPH-sgminer 4.1.0 with intensity set to 17 other settings re like this:
-g 2 -w 256 --lookup-gap 2 --thread-concurrency 3200 --no-adl


Card is not OC'ed... runnig stock and cool... with the Arctic Cooling Acellero Extreme plus II helping alot

core clock between 1050 and 1150, mem clock 1250, 256 worksize, -g 2, --lookup-gap 2, intensity 13 will get you running around 2.1Mh/s completely stable.
