Official ASUS X38 Boards: P5E, P5E3 - Info/BIOS Thread

[Mtrx]

[Right now I'm trying to resolve a minor problem: Every so often after I reboot from windows, the P5E will not post (no beep & black screen) and I need to hit the reset button. I'm trying a bit more dram voltage and adding some VTT. See more sig for details Any suggestions?]

Same happened here with fsb higher than 1600. Now with vtt at auto, nb at 1,31v and giving +0.02v to the ram that issue seems to disappear up to 1700fsb but can´t confirm yet because still testing.

I reboot windows 10 times continuously and that issue has disappear with that configuration. I can´t go higher with my system, the quad isn´t stable at 1752fsb (8*438) and temps pass for much 70ºc. Have you tried with nb gtl voltage reference at 67x instead of auto? I tried both and see no differences, at least up to 1700fsb, no more issues rebooting in both cases so I leave it at auto, but I´ve read that can help with 1800fsb.
