Ive spent all day running tests on my MSI Twin Frozr 7950 (with 7970pcb, ASIC 60%) and the highest I can go is 1105 Core and 1505 Memory with default voltage. No other voltages helped me get to higher speeds. The strange bit is that when I try a higher clock speed and Heaven 4.0 crashes, setting my clocks back to 1105/1505 performs 30% slower than it did before the crash, resulting in me having to restart my computer. I have read about OC speeds way higher than this, and while I understand that it's a lottery when it comes to how well your card OCs, it seems like this is way off the '1200/1800' stories ive read. I have the power limit up 20%, should I get a hacked MSI Afterburner to make it higher? Thanks for your help.
