John,

Honestly your board should run on defaults, minus the changes required to boot it (find disk and boot OS). I always turn on VT/HPET.

I use the outside rows for RAM, ie, the 2nd one and 4th one from CPU. I would not underclock your CPU, just let it run normal, run everything normal. do NOT select the reference memory freq other than 400 if your cpu is 400. I have issues with this when I use other values even when I had 1333 RAM.
