Overclocking problem

[Radeghost]

Hi.
My PC:
Intel Core2 Quad Q6600 2,4 GHz B0
Asus P5N32-E SLI Plus
2x2048 800mhz ddr2 Corsair RAM
Zotac GeForce GTX470 AMP!
Chieftec GPS-650AB A [650W]

Here's my problem.
I can't OC my CPU. When I'm overclocking it to 3ghz (fsb 1333mhz up from 1066) with normal voltage, it resets after few minutes. Temps are fine, 48-50 degrees. When I OC'd, with vcore voltage up to 1.45v, I had blue screen after 10 mins of diablo 3. Temps were fine too. Oh, and multiplier stays at x9 and memory is unlinked.
Any ideas?

Did you stress test to make sure the OC is stable?

I can't do this. Everything seems fine, but it just resets after few minutes.

Then it's suggested that you go and read some guides on overclocking before jumping in.

Set your ram to 800Mhz not 1333 or 1066.

Then overclock the cpu to 3.0Ghz and try vcore at somewhere between 1.35v-1.42v

Boot into windows and test using Intel Burn Test (standard test 10 passes).

Also look up some guides online if you need more help.

My ram is at 800mhz, because i set it at unlinked. my fsb is 1333 mhz, I tried vcore 1.4v but it didn't help.
