Why is my CPU voltage changing itself?

I have the AMD FX 8120 and I can get it to 4GHzish but my cooler is not being nice (I ordered a water cooling kit so I can overclock more). The thing is that at 4.2GHz I put it at 1.3V (actually a bit over that) but CPUz reads it as 1.4V and so what is happening? Also this happens with any voltage like 1.825V is 1.8V but this time the voltage is way off.

  1. Is this under load or at idle?

    What do you have your LLC set to?

    And 1.825v?

    Is that a crazy RAM overclock or something?
  2. I messed up, I meant 1.1825V is 1.18V. This is at load, I don't know what LLC is, that is the stock 3.1GHz voltage... I think.
  3. Let's try and get at the information another way:

    What settings did you change to get your current overclock?

    BTW, LLC is load line control and is a means of reducing v-droop.

    About 1.4V for 4.2GHz but it says it's using 1.44V.
  5. Not all softwares are always correct. ex: cpuz said i have core2duo processor in laptop but I have only dualcore (Compaq c772tu).this happens to me 6years before.

    That's only a single setting and there is more than one way to change the voltage. You probably changed at least two (possibly more) other settings to get to 4.2 Ghz.

    Oh well....Just set your voltage 0.02v lower than you want and see what the happens.

    I think there is some power saving mode that does that :).
