ASUS P8P67 Pro/Evo/Deluxe OC discussion thread

[Forceman]

EDIT - After doing this again how you said it seems to have somewhat worked...but seems finicky. Voltage doesn't seem to be dropping with the processor speed. Hmm...hopefully some others can chime in with their experiences on this.

Voltage will not drop if you set a manual voltage, only way to get it to track processor speed is by using the offset mode.

Oh I see! I only remember watching the voltage drop when I first built the computer at default settings. Makes sense. Thank you very much for your help!

[G_Sup]

Wouldn't it be nice if we could have the best of both worlds? Set the voltage maually as sort of a threshold, but at the same time have it throttle down when needed?

Also, could you (or anyone) explain the offset mode exactly? I looked in the book, but it doesn't really say too much. Maybe this has already been explained somewhere on the forum. I'll look around as well.

Thanks.

I know the theory, but not the way it really works. Offset just adds (or subtracts) whatever voltage you specify to the base voltage. So if the base voltage is 1.2 and you need 1.4 for your overclock, you would specify a +0.2 offset. Problem is knowing what the base voltage is, and I haven't seen anywhere that spells that out - so I think it is trial and error where you have to set an offset, then check, then change the offset, and repeat.

Since I can't get mine to sleep above 4.5Ghz, I am just using Auto for now, and it works as advertised - a little high on the load voltage, but nice and low at idle.

I see...thank you very much for the explanation.

Trying to decide between the Pro or Deluxe for my OC/gaming rig.

Wont use any of the additional features on the Deluxe, and will likely do crossfire later on.

It's $100aud diff between the two...so really, when does the 16phase help? I really wanna get a 2600K as close to 5ghz.

Will a Pro suffice?

But it really depends on the 2600K cpu you get from what I read on another forum where a Asus rep posted basically saying that -----> Expectations regarding K series overclocking in general and on ASUS P67 motherboardsPrior to the recommendations on overclocking the K series, I am outlining our results to set expectations.
The results below are based on the range of the CPU turbo multiplier when overclocking.
Results are representative of 100 D2 CPUs that were binned and tested for stability under load; these results will most likely represent retail CPUs.
1. Approximately 50% of CPUs can go up to 4.4~4.5 GHz
2. Approximately 40% of CPUs can go up to 4.6~4.7 GHz
3. Approximately 10% of CPUs can go up to 4.8~5 GHz (50+ multipliers are about 2% of this group)

Hope you are one of the 10% or 2% which finds that golden cpu..

They might've been talking about the auto OC feature? Or some arbitrary voltage ceiling? Much more than 10% of the CPUs I've seen can do 4.8+

Hi, I have my 2500K stable at 4,8Ghz, he made it thru 4,9Ghz but I needed to give him more cpu voltage, wich I'm not confortable with...

The problem is, that after all tests he's stable, but when I turn it on the next day, the mobo doesn't turn on, it just reboots 2x times and the EFI gets the cpu in stock mode.

Does this happen to anyone? Or is it just me?

Thanks


EDIT: Sorry, didn't saw this thread

Anyway is it true that 1,35v is the maximum safe voltage for the Sandy cpu's?

[Kimi.Rk]

I consider gold chip?

[V3ctorPT]

I have a golden chip too with less threads, but golden too

[MaStA]

I have a golden chip too with less threads, but golden too

Lets see it stable after like 5 hours of Prime95.

[Kimi.Rk]

I have a golden chip too with less threads, but golden too

but you will have 4 active threads 2500k.

[KGB7]

but you will have 4 active threads 2500k.

I have to raise vcore on my CPU to 1.44v if i want to get it to 4.8Ghz.

That is just unfair.

can anyone help with this?
This usb device error never stops, pop up every 2 sec.
I only have connected mouse and keyborad.

Actually I think most can do 5Ghz, but most of us don't want to push that much voltages to our new CPUs.

Did you install all the drivers that are on the cd that came with the board? There are quite a few.

As someone said, make sure you install the drivers on the CD. I think one has the word management in it and that fixed an unknown device in the device manager for me.

Anyone else having strange behavior with the PCIe slots? I am having the sleep problems, and while troubleshooting (lots of sleeps, tweaking BIOS, etc) I started getting problems where it would boot with no video, and with the red VIDEO LED lit. Got to the point where it wouldn't even boot off a hard power off. Finally got it working again (not sure how), but not my top PCIe slot is reporting (to GPU-z) that it is running at x1 1.1 - and video performance confirms that. I tried the lower slot and it runs at x8 2.0 (as it should), but all attempts at using the top slot all result in it running at x1 1.1 (for a while it was x1 2.0, but now not). Any ideas? I'm leaning towards defective board, unless someone knows of a hidden power saving setting or something that might be causing it.

Reset your BIOS and set it all to default and see if you still have an issue.

You need to start from scratch.

Yeah, tried that. Also tried to flash back to 1053, but of course that is a no-go. Tried both clearing CMOS, and loading defaults, same problem both ways.

Just got my new box running. Only a few minor glitches so far.

1) I'm using a manual fan controller. It wasn't obvious how to disable the BIOS CPU fan error warning. You have to set the minimum fan speed alert in BIOS to Ignore.

2) The "No physical disk" BIOS error is annoying, even though there is a disk. Easy enough to troubleshoot, I just turned off the Marvel and JMB devices in BIOS since I have enough with the Intel devices. As a bonus, it boots up a lot faster now.

3) CPU temp was steady at idle around 32C. When I upgraded from factory BIOS to 1003 BIOS, it jumped to 48C. It still reports around 32C in software like Asus AISuite Monitor, so I suspect the BIOS has a glitch.

4) The diagnostic LEDs were helpful troubleshooting an error that resulted in lots of beeping my first power-up. Turns out I forgot to reattach the 6-pin cable from my GPU to the power supply after I had re-routed it.

5) As mentioned, I also had the unknown PCI controller in Device Manager. I found a thread on another forum that correctly identified it as the Intel Management Engine Interface utility that you can get from Asus in the utilities section of the download area. Sounds like you can also just disable it, too. This was my fault, I didn't bother with the CD/DVD setup that came with the box, I just grabbed the latest drivers from Asus and considered that one as unnecessary at first. Still not sure what it does.

Other than that, so far so good, but I haven't had it running long enough to do any testing or overclocking yet. Took me half a day to get the dumb cables routed nicely- hardest part of the whole job.

System: P8P67 Deluxe, i7-2600k, 8GB CMZ8GX3M2A1600C8, Lian Li PC-B25S with Scythe flex fans, EVGA GTX580, Corsair AX850, Noctua NH-C12P SE14 cooler, Crucial c300 128GB, Win 7 Pro 64.

So far I'm running stock speeds but using the XMP profile for memory at 1600 CAS8 timings. Windows mem test ran fine in basic and standard modes. It's taking forever on Enhanced tests, it stuck on 21% for a few hours but finished with no problems detected.

Otherwise, seems to be running well and is ultra quiet on medium fan settings, even quieter than my Q6600/Radeon5850 system in an Antec Solo case that (subjectively) moves less air. The new one is inaudible on low fan and the idle temp only goes up a couple degrees. On high it is clearly audible but is also moving a good amount of air.

Should have no problems with the games I play. Granted, I had no problems with my last box which is now the kids' gaming machine. Now I just need to order a 120Hz monitor.

Then you have a bad mobo.

I had a Deluxe mobo that was making loud electrical noises when i ever i moved my mouse. I exchanged it to Pro, still same issue, then i exchanged it again for another Pro. And now i have a working mobo with no issues.


At times you just get a bad batch. Mobo makers rush when they make the product at first, thus making more mistakes in the process do to high demand.
