Its running at 400mhz but shouldnt it be at 800mhz? Is it because my FSB:DRAM is at 5:6? Im running an e6850 stock at 3.0ghz, x9 multiplier, 333 FSB, 1333mhz Rated FSB. Running a crappy P5N32-E SLI board.

Cpu-z shows a number that is half the speed your memory is running. It is running 800 mhz.

DDR = DoubleDataRate. :up:

The CPU-Z speed is correct, 400mhz for DDR800. Dual data rate memory transfers data 2 times per clock cycle which is where the name comes from. 800 is the effective data rate, 400 is the actual frequency.
