Problem overclockng my i5 2500k on an MSI P67A G43 - Page 2

Turned off spread spectrum and it is now at 100mhz smile.gif

That hissing sound is still bothering me, though...

Hissing is gone after I down clock from 42 to 40. And now my CPUZ is reading at a constant 4.0MHZ instead of sitting at 1.6MHZ

I give up.

The noise is not coming from your CPU, it's probably coming from your motherboard. I had the same thing happen to me.
It dies down after a month or so. The noise isn't bad, just weird to hear.

I took my 2500k to 5.2GHz on the board that you have without much problem. I ran it a 5GHz stable though (check sig).

EDIT: Are you stable with that amount of voltage? Doesn't seem like much. Mine took 1.25v for 4.2GHz.

Ya, I figured that out after some googling. Why does it make that noise at 4.2 and not 4.0? My system is running stable right now. Is the pch 1.05 option in bios to increase the voltage?

Core Voltage at 1.336... a little high, isn't it?

You shouldnt need to touch the pch. And yes that does seem high. I went to 4.7 @ 1.344. But every chip is different and iirc the newer batches haven't been the best OCers.
Is that the lowest you have managed to get it stable at?
Did you set that or is that on auto? If its auto, many boards Including out MSIs way overcompensate on vcore.

the downclock to 1.6ghz normal because of speedstep.
However, when cpu gets into load, it will revert back to your overclock of 4.2ghz. Nothing to worry about.
Don't set your vcore to auto. Select manual as there is no offset option for this board, and type in like 1.25-1.27
That should be plenty for 4.2 overclock.
Also, i noticed this board likes low vdroop, so you might wanna try that as well.

It's set to auto. I don't know how to change the voltage on my msi bios. I could have sworn I've spotted it before, but I think that was just me looking at the pch list.

How come there is no option to change my vcore? All I see is pch, dram voltage, and internal pll over voltage.
