New System Squeal

I just finished my first real comptuer project http://blog.techedout.ca and as soon as I pass 3.8ghz on my overclock I get a constant squeal, I think from my motherboard. From what I understand this could be coming from the capacitors but has something to do with power. Is my OCZ GameXStream 850W enough juice for my system to go that high? Keep in mind I am running 2x8800GT's, 2xSATAII, 2xDVD+RW and plan to have 4 sticks of Corsair Dominators when I'm done. Please help.
 
Actually that PSU can only provide about 500W of power cleanly and reliably. Any higher than that and you'll start hurting the PC. So keep that in mind.

But you might be borderline at that 500W limit if my math is correct. However, listen to the PC next time when the squeal happens and find out where exactly it's coming from.
 
I have an antec P182 case and it's definately NOT coming from the lower compartment where the PSU is. Somwhere around the ram, CPU area on the mainboard I believe but my hearing isn't so great.
 
I would DEFINITELY check the capacitors on the mobo and PSU. Look on the mobo and see if there are any bulging or looking like their about to go. If you hear a squeeling sound and you believe it's overvoltage related... it's probably a capacitor taking some damage.

What voltage are you running the proc at?
 
You responded before I did and I didn't notice it. It's probably a capacitor then if it's coming from the mobo.
 
I did push it a little past 1.6v to see what it was made of but as soon as it squealed at me I backed it right back down to 1.45 - 1.5 until I figured out what was happening. 1.55v is where some off chance squealing starts (during prime95).
 
Capacitors very rarely squeal. The issue is almost certainly a result of one of the coils on your motherboard vibrating at a frequency in the audible range. If you can isolate which coil/coils is/are causing the noise, then it's possible to dampen the vibration by using a little bit of glue to stop the vibration. Try taking a piece of plastic tubing, stick one of the tips just inside your ear, and use the other end to poke around in your case so you can isolate exactly where the sound is coming from.
 
Thanks, I'll give it a go when I have some time but for now she is sitting at 3.6ghz and 1.475v with no sound.
