Backgroud noise, possibly due to overclocking?

Hi there, I seem to be getting a high pitched tone coming through my headphones albeit at a low volume (still irritating), this becomes more noticeable when I play something like css which is cpu intensive.

Noise occurs whether I use my onboard sound or my X-Fi card.

My specs:
[email protected] stable
Gigabyte P35 DS4
8800GTX (stock BFG OC)
2GB OCZ 7200 ram

Any ideas what it could be? Don't want to lower my clock really.

Cheers.
 
It's possibly coil whine - possibly from the gfx from your description of when the sound kicks in, but it could equally be from the PSU or other...

Unfortunately, the only way of testing the above is by swapping out the suspected components.

However (from memory), some members have cured the problem by disabling speedstep and manually setting the core voltages in the BIOS - it's certainly worth a try.
 
I'm getting this same issue when my settings are on default in my bios. When my computer is overclocked i don't hear this sound.

I got a Gigabyte UD5

Hmmm, I thought it might be speedstep etc so I enabled them all again. That didn't make any difference for me. My previous psu blew up around about when I installed the E8600, I just replaced it with something that we had spare in the house (OCZ).

What power supply do you have?

Thanks for the help so far.
 
First step is to write down your bios settings then set them back to defaults, see if the problem persists. If it doesn't, the argument that your psu is struggling is stronger.

If you connect speakers, instead of headphones, and turn them up a bit while no sound is playing, do they make a similar noise? If the cables are unshielded (like mine) you'll hear something regardless if you turn the volume up enough, but it's a step towards working out if its the headphones at fault.

My friend had an issue with a constant hum coming through his speakers, running laptop into usb sound card into amp & seperates. The hum went away when the laptop was on battery, turned out toshiba had done a poor job of isolating the ac input from the sound card. This was resolved with something put inbetween soundcard and amp that filtered this out, couldn't tell you what it was called offhand though.

Oh, no hum from my ud5 through headphones, direct from soundcard or via speakers, stock or overclocked. PC P&C 860W.
 
Just tried my Logitech Z-2300 speakers, same sound is audible, even at lower volumes. I'm not sure my psu is struggling though, I've heard they often work perfectly despite high frequency coil whine. I'd be interested if there is some kind of adapter that shields this sound.

Might revert to stock bios settings in a bit; however if this sound does go away. How can I resolve it, as I'm not willing to lose my clock speed to eliminate the sound really.

You could experiment with different BIOS settings/clock speeds (e.g. greater multiplier less FSB or vice versa) - all within a tolerance that you still find acceptable - and see if one eliminates the coil whine.

Obviously, this will be time consuming and may not yield a satisfactory result – but it’s probably worth a couple of hrs of testing if the noise is irritating you that much (understandably I might add.)
 
Could anyone expand on what they used exactly to fix the front panel emi issues please ? thick ferrite ring ? thin one or clamp on ? and one or two or 3 ? one near the sound card end and one near the front panel end ?
