P67 board replaced...cpu voltage increase

[kr4tos]

Hi everyone, this is my first post on these forums.

I am new to building PC's and I hope to start overclocking as soon as I learn more about it.

Current Build:

i5-2500k @stock speed

P8P67 Pro-bios version 1305

Noctua NH-D14

G.skill ripjaws DDR3 1600

Corsair TX-650

I recently had my P8P67 Pro replaced due to the P67 recall. At the same time I decided to throw in a nh-d14, as I plan on overclocking. The first boot after replacing the motherboard, I noticed that the cpu core voltage peaks higher than it would on the previous setup.

Previously:

P8P67 Pro-bios version 804

i5-2500k @stock speed

CPU core voltage peak: 1.21V

Stock Intel cooler

G.skill ripjaws DDR3 1600

Currently:

P8P67 Pro-bios version 1305

i5-2500k@stock speed

CPU core voltage peak: 1.31V

Noctua NH-D14

G.skill ripjaws DDR3 1600

Everything else in the system has stayed the same, including the RAM overclock. Only the motherboard, along with a bios update, and the CPU cooler have changed. I was wondering if someone could help me with this issue. There seems to be no reason why the voltage should have increased by .1V after changing the motherboard. If the motherboard is the problem then I'll probably try to get it replaced, but I hope that I don't have to.

My main concern is overclocking. It seems that the CPU is now drawing up to 1.31V when under heavy load, which seems way too high. But I am new to this and I am looking for some advice on this issue. It shouldn't be a problem with the CPU.

Why do you think the CPU core voltage has increased so much and what can I do about it?

welcome to the forums.

i am not too knowledgeful on intels

im sure you will get an answer really fast here, as there are ALOT of intel freaks on here

[a compliment - not a dissing!]

Strange, it should only be using ~1.2v at stock, you could have a faulty motherboard. Have you changed any settings in the BIOS?

It shouldn't be using that voltage at stock, i'd overclock to 4.5ghz using the same volts but you may need ~1.32v to get it stable.

I'm not sure if it would cause damage at stock but the volts are high for stock clock.

EDIT: Forgot to say you could also try manually setting the voltage to ~1.22v if you want to leave it at stock.

I actually did some testing and noticed a few things.

I did a CMOS reset and booted using the default settings. The core voltage then became normal once more, peaking at 1.21V under heavy load. But once I tried to overclock my RAM using the XMP profile, the core voltage would jump up to 1.3V. After removing the RAM overclock, the cpu core voltage would then jump up to 1.26V under heavy load, and I could not get it back down to 1.21V unless I did another CMOS clear.

I tried manually overclocking the RAM, but it resulted in the same problem, and I could not get the voltage back down until another CMOS reset.

I suppose I'll just have to deal with slightly slower RAM for now.

Just overclock the CPU to 4.5ghz 1.32v should do it, that way you can keep you RAM OC. Just change the multiplier to 45 manually set the voltage to 1.32v and enable PLL voltage, set Load Line Calibration to Ultra High and Phase and Duty Control to Extreme. Also disable speedstep and turbo boost in CPU power options, you may need to set the multiplier to 45 in there as well.

shouldnt he also disable the C1E C6 and that other stuff?

im guessing LLC will fix all those high voltage spikes

I don't recognize C1E C6, there are no options like that on the Asus BIOS I haven't noticed them anyway.

They are in there. I think it's under the general CPU settings tab thing. Don't remember exactly how it was called. But it is there.

Must be a seting on the PRO versions and above it's not on my standard P8P67.

ones C1E, the other C6 and theres a third one... right under speedstep

Oh those, they go away when you disable speedstep so I never paid attention to what they were, just assumed if they go away they must not be needed.

Thanks for the advice. I haven't had the time to try this recently, but I will give it a go this weekend to see what happens.

did you had to pay something for the replacement? i meen, shipping or something? how many days did you have to wait to the new one arrrived?

Shipping was free both ways. Took about 3 days to get the replacement and my return was received and processed in 5 days.

 

[yuyo12]

thank`s for the quick answer bro. great info about shipping

BTW dude dont use XMP on a P67 mobo. Just set it all manually including the ram volts and youll be fine.

/Thread hijack kinda...

I do this with my memory, but what settings do I put all the ones to which I can't find specs on. Crucial only list about five main RAM settings but there are about 12 or so in my motherboard options, I just left what I can't find on auto..
