When overclocking an APU you will need to disable any power saving or turbo feature, once done, I initially increased the base clock to 104MHz with a multiplier of 40 and the GPU set to 960MHz, this brought the CPU speed to a nice 4160MHz, the GPU to 998MHz and the memory to just under 2500MHz. At auto voltage it seemed to handle this fine but wouldn't complete 3DMark11 or 3DMark without a BSOD. Aiming for top CPU speed, I managed to boot into windows at just over 4.8GHz however, I could not seem to get anything over 4.1GHz stable, maybe I was being too reserved on increasing the voltage. I did however manage to get the GPU running at 1100MHz but experienced another BSOD, maybe to do with the memory. Because of how intrinsically connected the CPU, GPU and memory are, getting the balance right is lightly more vital than ever before, at least this is what I was telling myself. So I decided to go for a sensible, cooler friendly 4GHz overclock with 960MHz on the GPU with 2400MHz memory.
