help me im a newb

I have 2x512 corsair ddr 3200 dual channel at 400mhz. With CPU-Z it say that my ram is single and im running it to 154mhz. I changed it on the BIOS but the screen doesnt want to open. My board is a P4C800-E-DX and I have the OCZ ddr ram booster(3.2volt).

help me plz, i dunno whats the prob with my ram.

are you sure that it is the right slots for dual channel to be enabled?

Ok fine, im on dual channel but how can I be 1:1 (now im 5:4) timings : 2.0 - 2 - 2 -8 - 8 (bios) and 2.0 - 2 - 2 - 8 (CPU-Z)
