I just bought this system a couple weeks ago and have been slowly over clocking it (I am new too over clocking).

So far I have managed to get up too 2403MHZ with 1.45V and stock cooling. I can run prime95 Small FFTs overnight with no problems however if I try to run the Large FFTs test I get errors within 10mins to 2 hours.

Also occasionally i will get the blue screen of death and my computer is rebooted.

I have the sets in my bios as

HTT= 267
Multiplyer=9x
LTD=3x
Vcore 1.5V (seems to under volt as cpu-z, the bios, and smartgardian all say the cpu is getting 1.45V
Chipset 1.5V
DDR at near stock speeds and memtest runs all night with no errors. running at 2.9v

My temps are 30-32C at idle and 40-43C at load for CPU
36-40 for PWM IC and 43-47C for chipset.

I would really like to get my cpu at a stable 2400mhz and I must be close if I can at least run small FFTs all night with no errors but I am lost as to what I can tweak to gain stability other then just raising the cpu voltage more (would that even help?)
