Until recently I've had no issues with my cards but noticed in the past few days that one of my cards throttles back to 157/300 and the other stays at 850/1200. They used to both throttle back when in 2D. Not sure if it is a catalyst change, afterburner or what. I've never experienced the gray screens or any of the other issues I've read about. These are MSI R5770-PM2D1G flashed with the Asus bios running at 1000/1350 since mid-November. Using AB 1.5.1 and rolled back CCC from 10.3a to 10.2 but still the issue. I'm not sure what version I was last using w/o the issue so I guess I'll roll back to 9.12 (I'm sure all was well then) and move forward unless someone has a suggestion.
