ASUS P8P67 Pro/Evo/Deluxe OC discussion thread

[DesertFox]

@DesertFox..Cpu c3 and cpu c6 leave at default (enabled) ASUS didn't come with the fix for it as of now
Try this
Turn Off your PSU,Clear RTC RAM (2-2 motherboard overview 12- in manual )wait 10~15 sec
Do not overclock RAM yet, let it run at stock frequencies
set your Vcore @ 1.38 (don't worry 1.38 is no big dill)
Internal PLL Overvoltage -ENABLE
CPU PLL VOLTAGE -AUTO
MEMORY FREQUENCE-AUTO


you can shoot strait for 4.7~4.8 with this settings

Ok I will enable c3 and c6, asus recommended that to stop it from freezing but I don't think it worked. Already cleared the rtc b4, made zero difference.
Ram runs at stock and cpu is @ 4.5 with vcore of 1.320
I have pll over volt off at this setting but enabled it for 4.6+
I set my pll volt to 1.8, I don't know much about this and would like to know more especially what lowering it does and if it helps sustain a lower vcore.
My memory volt is set to 1.5v and frequency is set to 1600.
EPU is off and extreme power options on all with 350 on the vrm freq.

Now my settings are totally stable @ 4.5ghz, only problem I can't install my old x-fi pci drivers, makes the system hang, but I think that's just creatives crap drivers, I don't think it's possible to install that card on an 64 bit system.

But my concern is, if I use asus optimized defaults, my os freezes, even though I'm running 24/7 at 4.5ghz without problems, that leads me to believe I have a dud mb and I want to replace it as I think it will hamper me from acheiving higher stable oc's.
And when I install an os i want to use stock settings to ensure a reliable install, although I think it mainly freezes when it idles at stock settings.
Either way I think I'm going to rma it on Monday, I'm just not sure wheither to get a replacement or a different board, on the asus forums I read other people with freezes, there don't seem to be many experiencing it but there are also other bug's problems with this board,
I'm regretting not buying the gigabyte board that I initially wanted but the reviews were good for the asus pro.

Here is a thread about the problem on the Asus forums:

I didn't read anyone here complain about it but would love to hear from anyone experiencing freezing at stock settings with the asus P8P67 pro.

I have the same freeze dude. I also have the 2500K overclocked to a 4.5Ghz, but at 1.32 my system wasn't stable though. Well, prime failed after 2 hours, so you might wanna try running more than an hour though. I managed to get fully stable with pretty much everything on default except for the vcore to offset > auto.

As far as the freeze issue goes, try to disable the C3/C6. It helped for me, and haven't had a crash for like 3 days.

I've actually enabled both c3/c6 now, will see what happens,
I was mainly freezing when idling at stock but running oc now.
When I have time I'll try run longer prime sessions but atm I'll just install some
games and try and get some real world tests for stability.
With the vcore I've set it manually to 1.32, ok it sucks that it idles at 1.32 but
when I was oc first I had it set to offset or auto can't remember and it flew up over 1.4v so I just set it to manual and it holds pretty much at that voltage.
Later when I have time I'll play around with the offset to get it right but I seriously can't understand why asus don't let u set a manual idle voltage and
a turbo voltage, then let the mb auto in between, would make my life less complicated

Well there's your problem!

Sandy Bridge isn't made to run at stock speeds.

Ye that's true

Have you tried the Microsoft hotfix - supposed to clear up random freezes in Windows.

If you are receiving random BSOD (Blue Screen of Death) under Windows 7 OS without any warning at stock or what appears to be stable OC settings, please download the following patch from Microsoft to have the problem fixed (98% fix rate): This hotfix will be in SP1.
