WHAT!!!??? How is your vCore at 4volts??? it should be more like the 1.472 volt range...what is it set to in the BIOS? Try setting it to auto..see what happens and post a Speedfan screen shot of your vcore spikes....

It sounds like a faulty motherboard, otherwise your processor would be pushing up daisies.

something doesnt sound right sensor might be bad. watch the voltage on the PSU itself with MBM or soemthing like it. if these voltages are going up and down more than +-5% thats out of a "good" range.

k, check the volts on the PSU like i said. if they are outside of the +-5% range you might think of getting a new PSU.

so for a 12v rail 12.6 - 11.4 would be ok.
