Does anyone have problems with Asus P67?"

[jsfitz54]

I mean, I don't suggest that overclcoknig is forgotten, but I do suggest that if you are going to overclock, that you do so fully informed of the potentials for failure, and understand the risks involved. This side of overclocking is not commonly talked about, but it is something I hope becomes more prevalent.

1500 Hours to hand polish a Ferrari crankshaft and failures should be far and few... It would seem that Motherboard makers need to step up their game.

If I blatantly abuse an overclock, I am happy to take responsibility. "Auto", should equate to dummy proof Manufacture "approved", as should XMP. (And I have had not such good luck with XMP on x58 as it really jumps overvolt.)

Yeah, you could. It would take an admin to fix the title, and erocker does have the ability to do so.

Most "auto" settings are much higher than they need to be for most CPU's needed voltages on most boards.

Here is the thing on that analogy...

You are asking that ferrari(cpu) to run past its redline (stock speeds) when you overclock. Intel only goes up to what we call stock speeds. That is intel's limit (outside of turbo). So I dont care if the crank is handblown unobtanium. If its only good to the rev limiter (turbo), its only good to the rev limiter.

Auto settings favor stability but usually add voltage to compensate.

OK,but when you enable it, howcome the actual CPU_PLL voltage doesn't change? You can test this using your MSI boards, or any other board that has read points...CPU_PLL does not change when this voltage is enabled.

It could be current provided. however, i noticed long ago that most boards have PCIe PLL chip, and these chips have two voltage modes...I am jsut as lost as you are with this one.


I mean, I recommend people not use it, because I myself have no idea what it does, and I seem to have a higher-level undertstand of board components than the average user. And with that in mind, not knowing what something does, in any part of life, is dangerous, so I'd rather err on the side of caution.

First, I dont fault that advice at all. If you dont need it, dont use it. But if you want to run balls to the wall, you will need to flip that switch for stability eventually.

Your question is a good one I cannot answer with anything technical. I can GUESS that while its phase Lock Loop, its not the same as CPU PLL. As we both know the other PLL setting I just mentioned if changed will NOT allow you to get past that same hump so there is (obviously) some differences there.

Im pretty confident it does adjust current level limits and that is why it allows overclocking higher. If it really has anything to do with multiplier availability (literally) then one would experience the flashing cursor instead of just not being able to boot in to windows/instability. As I mentioned, its been so long since I played in that area, I dont recall what happens so you could be correct.. anyone want to test?

Well then they should lock all the cpu's by your analogy...where is the limiter?

I think you can "edit" and go to advanced where you can change the title...

What a frustrating thread to read, I feel like saying "sorry for your loss(es)"

 

[arnoo1]

You're not the only one with badluck
No p67 though but i wanted to share
I have also board just die on me, these are the chipsets:
p45(p5q-ws, crappy mem controller sometimes it would not start with 2 sticks ram, after 4months oc unstable, ran prime 95 for 6hours and intelburntest 30rounds)
N780i (could not oc at all and mem didn't go higher than 800mhz)
Amd boards shitty mem controller, unstable,don't know wich boards, always on stock shitty cpu, vrm went into flames , on start up

And this is the reason ehy i have a gigabyte mobo atm, some times it bsod'ed , have to search what the problem is

Only for a limited time after the original post...might be only 5 minutes, even.

A few factors that could have contributed to the death:


"PLL OVERVOLTAGE" set to enabled.

"IMC Voltage(VCCIO)" @ 1.2v or higher

Ram voltage over 1.5v on a kit not designed for SandyBridge(every ram kit is made for specific platforms. Yes, they might work in another platform, but at the same time, if it wasn't on the board's QVL, then you are SOL".




That said, I do have a P8P67 pro, and an extra 2600K. Both are sitting in thier boxes.

This pretty much sums up my experience. My first 2600K back in January died after a few days playing with all the new settings, pretty certain it was the VCCIO over 1.2v that did it (was a Gigabyte UD4).

Since then I've had 4 other 2600K all on Asus P8P67 and Pro motherboards (B2 and B3) with RAM 1.5v everything auto. With those settings I've been crunching 24/7 @ 4.5GHz (1.35v) without any more CPU deaths.

Think you may have gotten a little unlucky though

The "Internal CPU PLL voltage adjustment" is not the same as what is labeled CPU PLL in voltage options in the BIOS. When Intel moved EVERYTHING on die, the cpu pll got moved too.

What is still called cpu pll votage under your BIOS options, refers to teh pll in the PCH. I am trying to get more detailed information for you. Having a little trouble finding the pinout for socket 1155.

 

[Wrigleyvillain]

Most "auto" settings are much higher than they need to be for most CPU's needed voltages on most boards.

Yep. And I wouldn't really trust what the BIOS/software tells you either, generally speaking.

I am very aware of the pinout of the socket, and I do probe every board I review with a multimeter to test voltages.

Unless and OEM directly tells you what it does, I think you'll not be offering me any new information.

I can change the title, if you want it done. Just PM with link and new title.

Agreed. But sometimes its all you have. Some dont own/wont buy a $20 DMM and/or there are no voltage read points (without looking for schematics and breaking out a soldering iron) on most midrange and lower boards.

This one is fine

Thanks, Paulieg

Just trying to help you out man.

 

[EarthDog]

I understood what you were going for.. please continue if you would (you are welcome to PM me over at OCF if you would like). Im struggling to find technical information that is helpful outside of patent info which is WAY above my head.

 

[cadaveca]

Just trying to help you out man.

I know, and I do appreciate the help. Unfortunately, I have done my own research into this, and I found nothing. So, like I said, if it doesn't come from a board OEM, I already know what's in the public domain.

Whitepapers with specifics can be found here:


Volume 1:
http://www.intel.com/content/www/us/en/processors/core/2nd-gen-core-desktop-vol-1-datasheet.html

Volume 2:
http://www.intel.com/content/www/us/en/processors/core/2nd-gen-core-desktop-vol-2-datasheet.html

As EarthDog posted, the only variable that makes sense is current limits. You can find this info in section 6/7 on Volume 1.

I was jsut stating that I have spent considerable time researching this, and given the limited info, I feel the only place this info can come from is the board makers, as it seems that it was them that added this feature, and not Intel, seemingly.


ASUS's take:

* Intel PPL Overvoltage ( for increased K series overclocking set to enabled )

Overall in our ongoing internal tests the maximum frequency now achievable ( under LN2 ) is 5.8GHz. At this time we do not have a compiled database to reference improvements in the overall scaling range or new % of CPUs able to hit 50+ multis. With that noted currently we are seeing generally a minimum of 2 multi to as much as 7 multi increases with this value enabled on applicable D2 and retail parts.
Example
A D2 sample with peak multiplier of 44 with PPL option enabled and corresponding voltage applied we have seen results of a stable 50 multiplier now able to post / boot and be held. ( previously without the PLL value the same CPU would failed to compelte a boot with a any multi exceeding 45 )
In addition to the increase of the multiplier range a “side effect” is additional Vcore needed to compensate for maintained post/boot and stability tests. The new voltage level do not align with standard voltage scaling ( on CPU already able to hit / sustain comparable multipliers.
Example
Generally 4.8GHz stability can be achieved at 1.400 – 1.425 Vcore now with PLL enabled D2 parts exceeding their previous max multiplier the increase in voltage would be 1.425 – 1.450.
It is important to note this option should generally only be used with D2 and retail parts NOT D1 parts. Internally we have partial results to indicate degradation of stability at previously reached multiplier values. Some internal testing has shown on limited samples that some improvement is possible (generally in the range of 1 multi possibly 2 )
In addition continued testing with the PPL option enabled and D2 or retail parts have shown some benefits to CStates being disabled when approaching, at or exceeding a 50x multiplier. An important note to keep in mind is that disabling CStates can considerably affect HD performance ( especially SATA6G ) Please keep this in mind when going for the highest level overclocks.

Right. You are showing a top of the line EVGA board with voltage read points (I think, top middle?), and a debug LED?

 

[John Doe]

Well yeah. lol. Just saying, it has onboard voltage read out so you can do it with an Analog multi by just making the sense touch.

 

[EarthDog]

LOL.. gotcha.. yeah, DMM/AMM doesnt matter. Just saying that most boards do not have that so software for most people is all they have sadly. BUT most people dont need it.. Auto or not. the voltages are higher usually than if you tweaked manually but there were only a rare few boards in my experience that really worried you about what it set.

Actually, it does matter. You should use Digital for this kind of application. Analog would have harder time getting down to the 3rd zero point. Analog multimeters are more suited for (example) testing a mechanical engine, where miniscule differences don't matter.

That said, yeah, volts aren't to be worried about at this time and date. Things are solid with mobos like these P67. That 780i I had blew though. It showed 1.20v when I put 1.35...

 

[EarthDog]

ASUS's take:

Thanks for that info Cad... now its just a semantics thing sadly. When you said the multi is unavailable, I took it as you cannot select it and successfully boot (meaning get to windows splash screen) with it. You CAN select it, just not get in to windows (but again able to use that multi).

Those multi's are there/available (meaning no blinking cursor), but it just wont boot to windows without enabling it.

And its funny, Im glad I re-read that passage as I was in the process of getting my salt block (one large grain of salt ) to listen to those people at Asus as they intially asserted that only 10% of CPU's could hit 5Ghz in their how to overclock posts...glad they now think its more
