I have read about issues with other people videocards ect.. before where they would make a high pitched noise. Well my board makes an annoying noise when I have the DES/C2E enabled. You know the 6 lights on the board, well this noise corresponds with the 2nd green led or 2nd phase power supply. So currently that is the light/phase that is on at idle on my computer and this noise is driving me crazy. If I open a program it will throttle up a little and then the sound goes away for a second or I get like a fast beeping sound when its throttling.

Any help? Should I RMA it??
I'm not sure what you mean - is it a high pitched whine/whistling from the mosfets under load?

If so I also have it during IntelBurnTest and other testing programs that max out the CPU. Found out yesterday that it also occurs when playing Crysis. From what I've read here it's normal.
Although I haven't tried disabling C2E to see if the noise will disappear.

If that's not what you're talking about, just ignore my post :-)
