AMD Catalyst Driver Version, and Driver History - 12.11 - Unsure how to acquire history.
Issue Details - CCC reports the core clock at 300mhz, rather than stock 900mhz core clock. Results in reduced performance in games - msot recently, Planetside 2. Attempted to bring the core up using AMD overdrive in CCC, as well as increases the fan speed - clicking apply yields no change. Tested with furmark in the hope that it would bump the clock speed back to 900mhz, unsuccessful. Appears to have occurred after plugging in a second display. Card also idles at 50*c, rather than the 38 I'd been getting previously.
