ASUS P5Q-E (P45) pre-view

[exhausted mule]

looking for some help with this slight oc i have.


I have a weird problem with this board. I'll start with what i have in my bios. Most if the stuff i dont need ie: ieee, lan, epu, is disabled.

cpu multi:7
fsb: 450
Pcie frequency: 100
fsb strap:333
Dram timming: 5-5-5-15 1:1
Performance level:11
Cpu voltage: 1.18
Cpu PLL:1.50
Fsb termination voltage:1.10
Dram voltage:2.0
Nb voltage:1.26
load line calibration:auto
Cpu spread spec: disable
Pcie spread spec: disable
Cpu clock skew: auto
Nb clock skew: auto
Cpu margin enchancement: auto

everything else is on auto/or left at stock settings

Ok. Now, I'm trying for a small everyday oc of 3.6ghz on the cpu at 450fsb (8xmulti).


Problem is.... i can boot easy at 8x450, get into windows run games, orthos, browse the net with no apperent instability. But the minute i try and reboot.

my oc fails.


This happens at very high volts for the cpu. nb... at 430x8, 450x8, 430x7.5, 450x7.5 Tried higher vtt (1.14) and i think i tried 400 strap (wouldn't even boot from bios)

Board ran fine at stock fsb/cpu speeds with other settings in bios. This only started once fsb/cpu speeds where adjusted.

Can you guys see a setting in there that would be the cause of a instable reboot?



edit: hardware.
