Try changing your advanced clock control to 800/800/0/50. You may need more mch 1.40-1.440v . Also you may have to up your trfc with that ram, try staticTread value of 9.

I got the UD3P (rev 1.1 F9 BIOS) 3 days ago, want some help with settings:

Q9650 @ 4.15GHz, 1.312v load (LLC enabled) rebooted P95 Blend at 7hrs. I had raised CPU Ref from AUTO 63% to 65%, but should MCH Ref be same as CPU Ref? I still have MCH Ref @ 63%.

63->65% CPU Ref gave me 1.5hr more on P95 Blend before reboot.

Also, if I use 2.1vdimm, should the other "dram voltages" be set to 50% of vdimm, or atleast above 0.900v ?

CPU and PCIe drive...I read forum posts the new F10b defaults these to 700mv, I set 800mv on both, would I benefit setting them 700mv ?

MCH Skew, used 50ps on earlier attempt, rebooted 1hour earlier than 0ps.

Don't have much left on AUTO, PLL and ICH are set 1.5 and 1.2v and rest on Normal to prevent overvolting. I also read somewhere, PLL 1.50v overvolts and 1.45v would be fine ?

Oh, and vcore... Shows up in cpuz with 16mv intervals....1,280, 1.296, 1.312...same in BIOS "PC Health", nothing inbetween.

My 1.3500v BIOS = 1.312v idle/load, seen ppl with 1.328v ..??

Ok, I will give it a whirl. Why would lowering my PL (staticTread) be better? Doesnt that tighten it down?

Yes but I have been able to run pl9 for benching up to 4700mhz. Unless you are trying to get stable at 4.7-4.8ghz, pl9 should be fine. Also, try setting your vtt to 1.20v, then set cpu ref to .785 and mch ref to .80 then bump vtt back up to where you need it. Take them off of auto.
