ASUS P8P67 Pro/Evo/Deluxe OC discussion thread

[Prestone]

Hmm...you did plug both the 24 pin and 8 pin power cords into the motherboard correct? Try resetting the CMOS and I think that Mem OK thing on board is supposed to auto configure your ram or something, but I haven't really messed with it much. Also, try one stick of ram opposed to all of them.

(...)

I get two problem there: The first is the really stupid one: my 12v atx wasn't plugged with the extention... the second was an ram incompatibility with the mobo. So I get two 4Gb kits of G.Skill 1600 and it goes as a new!

An other question: I have desactivated all the energy savings but the core ratio is still moving between 16x on idle and 33x on load... Why?

Thanks

@koc..yep 1866 seems like the way to go,it made the system a lot more responsive.I was 7-8-7-24@1600 now 8-9-8-24@1866 (stable under P95) and love it
always Gigabyte fan but this P8P67 pro is not bad at all

[tiesum]

You have to select "By Per Core (Cannot Adjust in OS)". With 1253, it would reset that back to auto every time you entered the UEFI. I flashed mine to 1204 and I'm not having that issue anymore.

I'm also on 1204. Still the same problem though. When I see the post screen I always see the standard speed of 3.3 GHz. When stressed in windows cpu-z (1.56.3) also shows 3.3 GHz. The Asus turbo-v software shows the correct multiplier I just entered in the Bios though (45x).

I was also gigabyte fan , but i think asus win this round .
BTW,nice result and timing man , have you try 8-8-8-24 ?

[Lu(ky]

Still on 1053 bios but happy with my results so far...

Flashed back to 1253. Same problem as on 1204. I'm starting to lose it... Already thinking about RMA but I don't know if the CPU or mobo is the problem..

[Leeghoofd]

Try these mate :







No need to change the offset value ( I was just testing some stuff ) and keep ya rams at 1600mhz. CPU will step down to 1600mhz when idle with the above..

[DesertFox]

I've had a load of problems with this board, at stock settings it kept freezing in windows 7, I simply couldn't use the computer.
I oc the cpu to 4.5 and it's working fine now, I tried 4.6 @ 1.335/1.345v but prime95 failed on core0, with 4.7 @ 1.375v prime95 failed on the same core0
I'm running it now and it's linx and prime stable @ 4.5ghz with 1.320v, I probably can lower the volt but haven't gotten around to testing that yet.

here it is @ 4.5ghz

prime95 1.325v



linX 1.320v


Cpu c3 and cpu c6 are disabled, should they be disabled or enabled

Seeing as I get freezing constantly having to reset/power off my pc at stock settings, is there anything I can do or should I just rma the board as it's can't be working within intels specs if thats happening?

Thanks, 8-8-8-24 is no go but I'm happy with 8-9-8-24 WEI jump to 7.9

@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

[deaffob]

Um, you put vDram to auto? Even Asus said that you should put that to your ram's spec. Anyway, did you change any voltage to be at 8 9 8 24@ 1866?

yep this was before I achieve my OC after that you can start dialing RAM to your standards ,my set is rated for 1.5V but at that V MB was overheating at higher clock ..simple v bump fix the issue,@1866 1.6V is all you need

[deaffob]

My rams are rated at 1.6v 7 8 7 24 @ 1600mhz. So I guess I'd need more than 1.65 to get 1866mhz :O
I'll get back to ya

[Sam_oslo]

Anybody has tried pushing one core higher and other 3 at lower speed?
That could be useful for single treated applications, but I'm wondering how would it impact the stability. Anybody has played with it yet?

Yes you need 1.65 or 1.66 , for my ram i need 1.66
also you have to lose memory timing , try 8-9-8-24 or 9-9-9-24

[deaffob]

@koc I see you have 8GB. Did you have to increase your IO voltage because you have 4 rams?

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:

http://vip.asus.com/forum/view.aspx?...Language=en-us

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

[KGB7]

I have one issue with bios 1204 and 1253. My PC will not go to sleep. My CPU is OC'ed to 4Ghz, all the BIOS settings are at their default setting.

[tool_462]

I was mainly freezing when idling at stock but running oc now.

Well there's your problem!

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

[koc]

@koc I see you have 8GB. Did you have to increase your IO voltage because you have 4 rams?

No i have 2x4G ram , and i set all the volts to auto except Vcore and memory volt ,

[crossg]

Guy's, What is the Memory command rate for the memory on this board supposed to be? I had Mushkin 1600 1.65V 7-8-7-24 and it set to 1T auto, bought some Gskill 1.5v and it goes to 2T auto. Had to set it to 1T in Bios is this correct because I see other posts with 2T?

Did some SPi with the new stuff but tighter clocks doesn't seem to be much faster.

Also anyone know what the PCI simple communications controller is?

There doesn't seem to be much difference running 2T or 1T with these chips - the IMC is pretty darn good.

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.
