Not enough then? Getting a 400mhz FSB using an E8400 definitely needs more power then?

I can't shake the feeling I'm doing something ridiculously stupid with the settings somewhere. Should I be using SPD for my RAM or inputting my own timings? Do you think that could be what it is? Everything runs great at 333mhz FSB
Also try timings by SPD. And then try to work with only 2*1GB modules.
