High pitch sound driving me crazy!!!!!

[james111]

I've used both the msi k8n neo and the epox 8kda3 and both of them had the same problem. When the system is both overclocked and at stock (more so when overclocked)

I get this high pitched sound/sqweel coming from the mofsets area.... i'm pretty sure the sound is from those rings with copper wire wrapped around it.

I've tried an enermax 470w psu, vantec stealth 470w psu, and a generic 320w psu but still get the same sound.

I found this but it didn't really help me.

and yes I am using a seagate IV harddrive, but i've also tried other one as well, but it's the same thing.

Back when I had my Abit NF7 using the same components, I didn't get any high pitch sound. Could I have just gotten two bad boards?

try putting it under load, then making it idle. Does it go away when its under load?

[james111]

Right now it's louder at idle then goes away when running prime 95

I have noticed something of my system also doing that while/after playing Painkiller....

[craig588]

For my its the OCP kicking in when the system is idle, when its under load its not a problem anymore because the CPU is drawing all of that extra current.

[ColdFlare]

its the 8kda3j or epox motherboard you have. Mine makes the sizzling noise too.

[xxORBxx]

I get the noise too.

Wow I'm gonna help ya all guys

It's the chokes! Take a pencil or something non-conductive and touch the chokes when they are making the sound - LIGHTLY!. When you get to the right one, it will change the tone/pitch of the sound.

This is your victim. All you have to do is put some non-conductive glue to secure it 100% and you're all set. I've done it on a videocard and on one of the NF7-S boards I had.

You got it kinda backwards as to how OCP works there you know?

Probably a newb question, but what are the chokes? and isn't a pencil conductive?

[Crankster]

No, isn't the wood is insulating it ?

Aw, I was just guessing. I happened on a board that people said something about OCP so I naturally assumed.

Guys - Chokes are ceramic dohnuts wrapped in copper

Did you try identifying the source of the sound on your mobo?

Btw, often there's a sound when scrolling - choke by the AGP on my 8RDA+ a while ago.

Cranox
I think if you google for "choke" in images, you should be able to find it. STEvil explained pretty good, though.

Crankster
Yeah the point is to use the wood to touch without causing a short-circuit.

james111
Nope you aren't trying to write anything with the pencil.. just touch - with the BACK end

[STEvil]

I dunno, never bothered tracking it down and my system is all torn apart atm.

[james111]

Ok I tried touching the chokes with a pencil but the high pitch sound continues

This has happened on two boards, do you think the cpu's causing this?

[Cranox]

When i press hard on one choke the sound is gone , but when i released it the sound is back

Thats why he said to put no conductive glue on there.

Now that weve found the solution, the sound is gone.

lol, ain't that the way it goes? This is good to know, for the future, thanx Ivan. My old 8RDA+ did that for about 3-4 months, driving me the same kinda nuts, then finally stopped. Maybe I bumped a choke into a more stable position. (?)

[Cranox]

Thx m8's , the sound is gone now

[IvanAndreevich]

Good that it helped some people. I know those things can be a real annoyance, especially when striving for a quiet system

mmmmhhhhhhh

[Reflex1]

i have the same noise when i scrol my mouse ...i'll try this when i get back home.

[Samael]

Is the LOGO Instant glue(cyanoacrylic) safe for that kind of work?
If not what is the best out there??
