Help!? Is this even possible!

I just bought and build a new computer and am OC the CPU. I have the e2160 and it was making windows vista unstable at 2.88 Ghz which is wierd because most reviews say you can get 3 without issue. So I booted up CPU-z to take a look at some things and noticed the voltage was lower than it said in the BIOS (1.325 supposed to be and only 1.6168 on CPUz). I bring up speed fan and it says that I only have 6.39 Volts on my +12 rail, as opposed to 12 V. I had this same PSU on my last rig and it worked fine. It is 575 Watts with +26 Amps on the +12 Rail so it has enough power to run the 8800GT, 5 fans, one HDD and on DVD writer.

What is going on???

Firstly, CPU-Z reads your actual CPU voltage under the cost of Vdrop and Vdroop. Doesn't mean that you set your voltage at 1.325v, it'll be at 1.325 constantly.

As for your PSU, thats a +12v rail which is counted through the amps. Not voltage, 6.39v is correct.

As to why your E2160 isn't stable would most probably be the account of heat, and may also be the fact that you got a low-binned silicon. Every CPU is different from one another, it doesn't mean that a person's E2160 can hit 3ghz fine at stock voltage and it will for you too.

Your solution would be to get a better cooling option. Other factors like disabling a few features in BIOS is needed as well as tweaking your RAM too.

Yeah, figured it out by myself. I am having a rough night, pissy and such. Nothing is bloody working.

I must have gotten a bad die sadly. I can get it to 2.85 Ghz with a little bump in voltage, but nothing more than that. I have an aftermarket cooler that has great ratings on these cards, yet for some reason, I can barely bump it to the next voltage setting before I am hitting 64C while running Prime95.

Did I just do a sucky job of putting on the Thermal Paste? I have a nice cool case (PSU with 2 fans, one sucking in case, one blowing out, one side one blowing air down on the heatsink of the CPU, the CPU fan that blows outward into the case, another one cooling my HDD from the side (blowing into the case) another one blowing out the rear and still another one sitting below the DVD drive just to circulate).

You think that would be enough to keep the processor under 60C. This is getting annoying.
