I wish i could help you a little bit Crash, but all the info that i will give it's from a C2D, not a quad ... anyway after a week and specially today (wanted to test if the chip really degraded or not) i found several things that are making my rig almost 100% stable with everything set on auto except the voltages and some memory timings, hope it helps you as well as all the other ppl hanging around with this P45 mobo's ... as they say on
this XS thread, the P5Q Deluxe it's a lil bit crazy applying the voltages, some are overvolting and another ones are undervolting, first i would do is to check yours with some DMM and adjust them appropiately, cause if you leave the voltages on Auto or the lowest available setting it will just overvolt as hell ... you can start with this if you don't have a DMM:
On my Pro it's not the same though, anyway i've been Prime stable (and some 3DMarks while Prime was on) today with these CPU-Z readings:
333x9 - 3000Mhz - 1.112V (memory working @ 800Mhz 4-4-4-12)
400x9 - 3600Mhz - 1.216V (memory working @ 800Mhz 4-4-4-12)
On all the configurations BIOS settings were the following (
P5Q Pro on-load real DMM measured readings), in this particular case is for the 400x9, BIOS Version is 0703 (official from ASUS):

I'm adding the shots of 3 & 3.6Ghz, i'm actually priming now for more than an hour with 4.05Ghz @ 1.344V, wish me luck
333x9 - 1.112V
400x9 - 1.216V
update: 450x9 failed to Prime after 2h30m with those settings
... i'm still trying to stabilize it 100% ... as soon as i get it i'll post the settings ... it seems this BIOS is a lil bit tricky
