Max on the power slider, 2900mhz on the core, 2150 on the memory. I've not tried anything higher yet, but have 50mhz to play with. It will hold high 2700 to low 2800 on games and benchmarks.
Hmm pretty much identical performance to me... mine maintains slightly higher clocks but nothing that accounts for 200pts.
Maybe because your CPU is quite a lot better you’re getting a slight boost overall.
