  1. It has automatically lowered it to 800Mhz as it is similar to idling. When you begin to do heavy gaming or video editing, the speed of it will increase by itself. This is simply to save power and put less stress on your RAM. Hope this helped.
  2. 800 is 1600, see the final column, xmp-1600 runs at 800Mhz.
  3. ook.. thanks for the info. I didn't know. Thank u guys :)

    DDR (and DDR2, DDR3) have twice the number of transfers as MHz. Technically the RAM is 800MHz, 1600MT/s. This is because it sends two sets of data with every clock cycle.

    RAM does not downclock like CPUs do, currently.
