Fluxuating cpu vcore issue

post #1 of 3
Thread Starter 
Sorry if I spelled fluxuating wrong, my main language isn't english. Anyway.. When I first got my mobo and my cpu; Asus M4A79T Deluxe and my Phenom II 955 my cpu didnt change between the vcore. Now for a while it did and I thought oh well that probably just happens to cpu's that's been oc'ed what do I know? But then I heard something about certain Asus boards having this option in the bios that enables the board to flux by itself between a certain amount of volt that you could set yourself.
I'm wondering if my board has this feature and I by mistake enabled it? I've got no idea what it's called or where to find it, ive looked through my bios but doesn't seem like I can find it.

If this isn't the case that my mobo has this feature, is it just normal that the cpu vcore starts changing then?

Regards!

*I think* most modern motherboards default to use power saving features which will fluxuate the vcore based on how much power the processor needs at any given moment. Usually you can disable all these power saving features and set a vcore to a specific value if you want.

yeah I thought that it was a problem at first but its not, its dynamic so it changes according to the clock speed which is also constantly changing according to load

edit: there are ways to stop it from doing it but its best not to, with it disabled your cpu will idle around 50-60 watts but with it enabled it will be around 15-20 watts. plus it does not effect performance or stability
