Should I be worried?

[LukieBoy007]

I built my pc just over a month ago now, and a week ago I decided to OC my Sapphire 7850 card. I get good temperatures and no graphical glitches, but sometimes (happened four/five times now in the past week) a loud squealing noise comes from the GPU? I have the Core at 1050MHz and the Memory at 1350MHz. I also have set the power slider to +25% (I am using MSI Afterburner.)
Should I be worried?
I am also running a i5 3570k (Not OC'd) and 4GB 1600Mhz RAM on a Corsair 500w PSU. I have read it could be something to do with the coils or something like that?
Thank you.

It is not a worry and often coil whine is audible. I am not sure of a fix but headphones will help.

Ok, thanks for the reassuring

Apparently having a capacitor on the PCIE connectors to the graphics card helps reduce the coil whine. This is taken from the Silverstone website. Some Silverstone PSU's have this feature.

Click the above link and scroll down to number 7.

To reduce electrical whine/buzz associated with high performance graphics card’s dynamic loading changes, 2200uF capacitors are attached to PCI-E connectors. This design also helps to maintain better voltage stability and improve ripple & noise performance.

Not sure of the validity of this as I have a Corsair PSU. Not everyone gets coil whine (I don't) and I think it may be down to the quality of the output in the first place. Putting a capacitor like Silverstone do is a bit like sticking a plaster on it, but hey if it works...

haha my sapphire 6950 is a screecher as well

Hmm I have a Corsair too. I can live with it I suppose as long as it doesn't get worse.
