Hmm, does this mean a new PSU is needed?

I was playing around with my newly acquired 4400+ X2 last night, and was loving the flexibility it had.

Its been a long time since i last overclocked, the last time was on my XP 1700+ :D

Anyway, i got my 4400+ yesterday to 2.58Ghz by upping the voltage to 1.475, however, when i go into CPU-Z the voltage is fluctuating between 1.475 and 1.5, does this mean that the voltage is unstable because my psu is under too much strain?

My PSU is an enermax Noisetaker 485W, so could this be the problem?

Also whats the maximum voltage you guys would recommend to put through my chip?

You can't trust the voltages from the monitors apps. Do you have a multimeter? But if it 4.75v, then it's 5% from nominal and not good. It's the 12v that sees the most load and usually suffers most. Max on air depends on cooling, but 1.5/1.6v

Yeah i might try the voltage meter thing later on, how would i go about doing it though? Is there a guide on these forums to do it?

So the max volts that i should be putting through is about 1.5/1.6 then yeah?

As the CPU voltage regulators heat up on my motherboard the supplied voltage rises acordingly from 1.7 volts (what the BIOS is set at) to about 1.8 volts.

And yes I know that's a lot for a CPU but it was just temporarily for testing at 2400mhz and I'm water-cooled so it stayed below 40C at full load. The only reason the voltage regulators are heating up is because my PC isn't at home in the air conditioned study with my other PC's and it's missing 4 80mm fans atm because there in my other, hotter, PC's

Currently maintaining 26C idling at stock volts (1.5) :D
(Ambient about 23C)
