bugle, cornwall (yay)
core 2 quad q6600 oc'd to 3.6
xfx nforce 680i sli
ocz reaper htc pc2-6400 800mhz
Ati radeon HD 5870
ocz gamexstream 1010w
Windows 7 64x 7600
tuniq tower 120 extreme

ok, i've had this ocz gamexstream 1010w power supply for a good 2 years now, and so far (i think) it hasnt been causing any problems at all. basically my problem is my computer seems to be making a few little high pitched whistles, specially if cpu gets under load, or until i started overclocking my computer and any fsb voltage over the stock 1.2v starts up the very annoying sounds.
i have my cpu oc'ed to 3.6 with the fsb at 1800mhz, so you can imagine what the sounds are like :P they're there all the way from the post screen etc.. and im definitely not going to go back to 2.4 just so there's no sounds.. in hawx the frame rate is great, it just lags, like slows down and speeds back up in half a second, EXACTLY to the pattern of the wierd whistly sounds.
I have stopped every fan i have in this thing (apart from the psu one) and the sounds still carry on. my system is stable and everything, never had issues with stalling etc. And now the fan on the side of the case (came with it, cheap, has red, blue, green, and orange led's) has stopped spinning, although ONLY the green light is on. i turned my computer off, checked the connection and it still is doing the same thing.
so is the problem lying with the psu? and when i add power from overclocking is that somehow causing some malfunction? you just have to hear the sounds to believe.. unless its the mobo, but how can electricity flows make high pitched whining noises? im more worried about my system at the moment then the noises, but i would really like those gone aswell.
 
It wouldn't be the electricity directly, but it sounds like a Capacitor whine to me which could be an indication that the PSU is on its way out if that is where it's coming from. Silly question but do you have another PSU you could try just to make sure it is that and rule out any other components?
 
only my brothers possibly blown gamexstream 850, i will definitely try that. if it is a capacitor, but on my mobo, would that make any difference?

i am going to try that power supply out now, it is not blown actually
 
ok, his thing is dead.. brothers are never trustworthy. i've been building my system up slowly, so have decided i will buy another psu just to be safe. What good modular psu should i go for for my system listed above? i am also going to be attempting to get my cpu to 3.8, 4.0 so nothing under 550w really, thx for your help, i would have never guessed where that 'strange' came from :D
not bothered about price, but dont want best of the best
 
What CPU voltage are you running at? 3.6ghz is quite a high OC for a q6600,

Just an idea but if you are running high voltage it may be a mobo cap thats not happy.
Try clocking it down to 3ghz, and drop the vcore accordingly to see if you still have issues.

my q6600 is the g0 version, so its running in bios at 1.4125, in cpu-z it can go down to 1.3825, fsb at 1.4, mcp at 1.4, spp at 1.5 bridge between the 2 is 1.2

stock standard its all quiet, but as soon as i go to 2.8 (only fsb - 1.3) the sounds start coming, although a lot quieter

edit: i have noticed it pretty much is as soon as you up the fsb the noises start. yet upping them by so little, surely that wouldnt make a difference to the psu now would it? so it could be the mobo, but would i not have severe stability issues if the mobo was 'acting up'? my board is not an xfx, its an evga. and these 680i chipset boards are supposedly good overclocking boards, so it should be getting what it can handle

and if so, i'm running my fsb at 1800mhz cpu multiplier at 8x, can that be a bad thing? my mcp temp never has gone higher than 61c, even after load and instant restart

i must ask though, as to me the voltages seem pretty low for such a high overclock, or is that ok? just to add to the above, the only voltages i changed for the oc were the vcore, fsb, and mcp, all others were on 'auto' and stayed stock. btw, i had looked on loads of forums, and the 1.4125v for the cpu was the perfect setting for other's q6600 g0 at 3.6, so nothing wrong with that. i get stability issues going down under 1.4
