That's the main reason I got the 1600mhz RAM. In order to hit the upper ranges of the cpu's potential, you really need ram rated for higher speeds to allow it to step conjointly with your Bclk settings. I force my RAM to 1066 before I set my OC and when I hit 3.8 it set the RAM to 1523mhz or 77mhz below its rating. Not sure how much headroom beyond the 77mhz I have on the RAM though as I haven't tried to go above 3.8ghz yet.
