On my old P5B Deluxe I could run at 1077Mhz (5-5-5-15) at 2.0v, so I was puzzled when this did not seem to work on this board. I am currently running 2x1Gb at 1037Mhz (3:4 at 5-5-5-15) with 1.86v, but according to AiSuite it is actually 1.95v. Memtest just passed overnight with NO errors.

A lot of people are having trouble running 4x1GB 1066 ram, especially Crucial Ballistix's, but they are just overclocked 800 ram anyway. You cannot beat G.Skill! I have not tried 4x1GB as I do not need it at this time. That is for another day. I have 2x1Gb in reserve.

This bios has some additional features which I am trying to understand before I mess things up. In fact the manual seem to be for the Maximus Formula and has not been edited for the P5E.
Thanks for the heads up! It's that type of insight that will help me avoid extra frustration. I wonder if that overvolting is something they will fix in the future bios releases.

I agree Gskill rules, use it in all of my machines even three laptops, never one failure or problem.
