that's normal for VDDC, the tiny drops are fine.
out of curiosity, what brand/model is your PSU? some are much more reliable than others. though with a 750w you should be good (but we can point you toward the better brands for a future purchase :] )
Thanks for the quick response,
My PSU is FSP750-80APG , it came with the original FX6840-01c (my original computer before upgrades). It has never caused me any problems that I know of, but I doubt it is anything special haha.
Ive thought of upgrading it, but a unit that could fry all my other stuff seems a bit intimidating ^.^ so Ill probably do it once I notice problems.
