Everest show's 11.88v to +12v. I keep trying, ocz memory's and radeon 4890 will arrive next week, perhaps things change (one way or other) after installing them. Still dreaming of stable 3.8Ghz! And will keep trying until i reach that magnificent point!!

A little. Your processor will still work after but it's not good for it.

Hmm...

I want to get 3.9 GHz for 3dmark06 but that will require a lot of voltage...

Any tips?

Realize that I'm no expert but I believe that 11.88v is too low on the 12v rail. Modern CPU's are almost all run on 12v hence the 4 and 8 pin connectors that are in addition to the 24 pin mobo power connections. Mine shows 12.35v in the BIOS and in Vista. Looks a little iffy to me. The good news is that 5 to 6 hundred watt PSU's are pretty cheap. Look for 80 plus efficiency for less heat and energy draw.

Eh 0.12 won't make much difference. It'd have to be down to about 11 or 10V for any significant effect.

Mine reads 11.90V all the time, but I got a 3.9GHz Overclock.

I understand what you're saying but my current PSU and previous 430 watt Seasonic both show over 12v. From what I've read, not that I've experienced, it's that overclocking with the IGP is harder (clock speed not multiplier). His 11.88v might be fine but Chieftec isn't a PSU that I've ever seen recommended for OC'ing enthusiasts. I'm surprised that your Corsair 750 watter shows 11.90v. Again, like I said I'm no expert.

Thread Starter 
In Everest it shows 11.71 under load and 11.78 idle. I got a lot of stuff conected, all the molex's are in use. Im using a molex to 4 or 8 pin cpu power cable as the hard wired cable wasnt long enough. i have 5 of the possible 6 fans connected to my fan controller and the RPMS on my cpu heatsink drop by about 100RPM as soon as i load up all core's, there is also quite alot of Vdroop, my Vcore drops from 1.575 to 1.555, it was worse when i had my athlon. Im not looking to get a new Psu, but if i did it would be a CoolerMaster 600W Silent Pro Modular PSU, but for this year i wont be up grading (i think).

Well, Right now I'm on an IGP and had no issues overclocking(RMA'd my GTX 260 to EVGA). And actually, It went up since then haha...It's at 11.97V now lol.. As long as you're within about 5% of 12V it won't effect much...Most newer PSU's have voltage protection for this(If it gets to low or to high it shuts off).

I do agree I wouldn't ever suggest or recommend a Chieftec PSU for Overclocking, especially since his PSU isn't 80 plus certified.

It may not be possible with your setup. Dont sweat it, youre getting good clocks already.
