High Pitched Noise around CPU area

Thanks for moving my Post Nikorr, but you got the Title wrong.

I am not getting the sound in the bios or boot, its only when i am in the OS i'm getting the sound

and just so people know when they look at this thread, im referring to this thread in my OP http://www.tomshardware.co.uk/forum/page-292915_12_50.h...

OK, just so u know, u can change the title by yourself anytime.

After all it is your thread now : )

/Click on the EDIT feature to change the title, not the Quick Edit./

Good luck!

I did try to edit it, but i get a message saying "you are not allowed to edit this message"  

OK, post it bellow and I will place in your changes.

Thanks

High Pitched Noise around CPU area

HI guys i am having the same problem as most in her in this thread http://www.tomshardware.co.uk/forum/292915-12-high-pitc...

I have

i5 2500k - Not overclocked & Stock Cooler
P8z68-v/Gen3
Windows 7 64 bit

Alot of Asus boards seems to be getting this after a few google searches.

I have narrowed it down to the power saving options. When i disable c3/c6 in the Bios then the sound stops

I also do not get the sound when i am in the Bios and while the Machine is booting up. It is only when the windows Login screen pops up it starts. Again as others has said, under load the noise stops too.

Im not to comfortable disabling the c3/c6 in the bios as it makes the cpu run at a constant 3.7ghz and makes my temps around 50C at idle and with the stock cooler.

Im not really sure what to do now, would really appreciate if anyone could give me any advice.

Managed to fix the problem.

It was the c6 state to be specific. Before it was set to C1E Auto, C3 Auto, C6 Enabled.

I set C6 to Auto, This stopped the whine, but this make the SpeedStep feature not work and the CPU was running at a constant 3.7ghz

So i Disabled C6 and changed C3 to Enabled and the whine has now gone, with the Speedstep feature working fine
