I have a Clevo P150EM Laptop with an i7 3610QM and a 7970m. I have done some benchmarks and all of them are indicating that my 7970m is performing better at it's overclocked (1000MHz Core, 1525 MHz Memory) settings, but when I play Battlefield in particular, which is the most demanding game I actually play, I am getting higher framerates at stock clockspeeds. Even a modest overclock is dropping my frames a bit. Is this happening to anyone else? I just repasted both chips and I have foil on the heatsinks, the laptop runs very cool.
