Hello , You will need to either try pushing the RAM Mx (Multiplier) but I think you will find that you wont get over 800 without OCing the CPU due to the fact the memory controler is on the CPU die, not the board and is only rated for DDR-II 800. Not 1066

Hello , ddr2 stands for double data rate, so for example in CPU-Z it will say 400MHZ but the ram is running at 800MHZ
