Thx for posting. Get your Memory down. I got it at 600. AMD can downclock to 150. Just play with your Bios.
In advance you can put your engine up to 1150... maybe 1200 depends if you want to downclock the voltage of your card as well.
Im running 3x 7950 @ 1.081 voltage and stable clock @ 1200
Do you have a link for compiled sph-sgminer 4.1.0 version for win7 to test?
I tweaked it a little bit, it won't seem to let me set the memory speed more than 150 less than engine.
at 1100 engine, I couldn't go lower than 950 memory, it would keep resetting to 1200
at 1120 engine, I couldn't go lower than 970 memory, it would keep resetting to 1200
