Is my memory running slow?

hi

i have 4 x Corsair XMS2 CM2X1024-6400

when i look at cpuz it says that memory frequency is 401.8mhz.
is this right or is my memory runnign at half the speed it should?

That's correct. What you have is DDR2-800, which has a memory clock of 200MHz; a I/O bus clock of 400MHz; and a peak transfer rate of 6400 MB/s

For future reference DDR means "Double Data Rate" It sends bits on the rise and fall of the clock. This means 400mhz clock, 800mhz effective.
