And thanks for keeping the thread up.
My board came with bios 203. I flashed to 502 because I had read about problems. I originally had trouble getting Memtest to pass, but after reading numerous threads on the Asus P5E Forum I solved my dilemma. This board's memory controller seems to overvolt memory.

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.
