Thank you very much!
Donations appreciated! Wink

Just did a clean uninstall/re-install with ATIman and installed 11.12 + the 2.5 SDK, the hash rate is terrible even though I'm getting 99-100% GPU usage (~482MH/s on stock settings with SDK 2.5, whereas SDK 2.7 did 550+MH/s). Also, "cgminer -n" identified my 7970's as "Lions" and not "Tahiti", so I'm guessing 2.6 and 2.7 are the only SDK's that will work properly with the 7970.. trying again with 2.6 before I return to 2.7..

EDIT: Just finished the clean 11.12 + SDK 2.6 install, and oddly enough it seems to not be crashing. Sometimes I can only run one GPU for mining because running all GPU's ends up with a cgminer crash. Currently have very reasonable CPU usage from cgminer (5-12%). GPU usage is still all over the place when mining with multiple GPU's.. some GPU's are hitting 93-99%, some are in the 80's.. its just a mess. Intensity at 14.
