safe voltages for a msi 970 gaming mobo?

[cowpker4life]

so im looking to OC my 8320 and i cant seem to get it stable at 4.4-4.5Ghz unless its at 1.520v what i hear is a little to high for the chip/bored even tho i see a lot of people saying the fx chips can handle 1.5v-1.55v before they are not safe. anyways cooling is not a problem and it really is will the cpu/mother bored work fine. at just auto voltage my its around 1.440v or something what is much higher then others i see with 1v-1.2v for stock clock speed is it just this motherbored drops a lot of voltage? also a lot of people are saying that the voltage is to much and the VRMs will get supper hot and maybe catch on fire. tbh i do not know what VRMs are and do not have a lot of experience with overclocking.
