2500k Overclocking Questions

Hello fellow nerds,

I recently acquired an i5 2500k and decided to give overclocking a shot.

my setup is as follows:

CPU: 2500k
PSU: OCZ ZS series 650W
Cooler: xigmatek dark knight
paste: arctic 5
case: lanboy

I set it for x42 multi @ vcore: 1.3v
Ran prime95 for like 30 minutes and watched the voltages/temps.
I am getting like ~51 degrees without the case fans all turned up which I guess is pretty normal.

So my questions are regarding the voltages (all under prime95 load conditions).
1. CPU-Z says the Core voltage is 1.200 V which I find a little odd.
2. Piriform's Speccy says that the +12V voltage is only outputting ~8.8 V and the +5 V HIGH THRESHOLD @ 2.822 V

Can anyone shed some light on this?

Thanks in advance

  1. 1. What do you find odd about the CPU voltage?

    2. Software is obviously reading the voltages incorrectly. If your 12 volt rail was down to 9 volts, your system would not boot.
  2. So for the cpu voltage I guess I was wondering if someone could help me understand why it drops from the 1.3V that I set, or more-so the ~1.24 V that my rig runs at while at idle down to the 1.200 V under prime95 load.

    As for the software, all that I can come up with is that the voltage that it displays is the voltage being used by the computer because at idle the number goes sub 1 V which makes sense because the computer uses more power under load (P=I*V)

    I have a new question regarding my set-up and the multiplier.
    I seem to be only able to get the multiplier up to x43. When ever I try to do x44 to x48 (while varying the voltages from 1.2V to 1.4V) the OS does not load. Any thoughts?
