Memory doesnt show as ddr 800 MHZ on a Gigabyte board

I built this machine with the components listed below a few months ago as a basic work workhorse. I never really paid attention to it but when i installed easy tune 6 the memory shows as PC 2 - 6400 (400 MHZ) not at 800 MHZ. any ideas on why this is ?

Go into the BIOS with a <DEL> at the first POST screen; on the "Advanced BIOS Features" page, set "AMD K8 Cool&Quiet control" to "Disabled"; your system is likely 'down-clocking' to save energy...

"Double Data Rate" Actual 400mhz, but 800mhz effective.

thanks for the response but i am confused by what you wrote. do you mean its running at 800 mhz ?

yes, however the clock is running at 400mhz. This is how DDR works... it sends data at the rise and fall of the clock tick.
