Howdy All,
Just now starting to overclock my E6600 on my eVGA 680i motherboard. My BFG 8800gtxes are in for RMA (missed pre-launch recall and had bad resistor). So, I'm using an ATi Rage 128 PCI card for my video!
Anyways, noticed something really odd. I'd heard of capacitors on video cards, PSUs, and motherboards making noise before. However, I'd never heard of a squeel coming from (what I believe to be) the CPU before. At least, not a recent vintage CPU.
At stock speeds, it doesn't happen. But as soon as I overclock my CPU to 3.15GHz (350x9), I get the following. . .
About twenty minutes into running Dual Prime95s, as soon as it starts the 8k fft tests, I get a faint (though clearly audible) warbling squeal from the CPU area of the system. It's defintely not the psu. Though it could be a cap near it.
The oddest part is that, like clockwork, it only exhibits the sound when the 8k fft tests 1, 3, 5, 7, and 9 are running. The even numbered tests do not produce the sound. Huh!?!
The noise stops as soon as I stop one Prime95 instance (freeing up one core).
The only thing I've done in the BIOS is up the vcore to 1.25v and raise the FSB to 1400 (350x4). Temps remain in the low 40s and never approach 50 (via Core Temp).
So, is this a bad sign for my E6600? Is it more likely that the sound is coming from the motherboard? Anyone else getting anything similar? Would be a shame if either one of them croaked!
