Vcore too jumpy

My CPU vcore seems to be too jumpy, and it's so inconsistent that it really decreases my stability when trying to overclock. Like at 2.4 ghz i need a lot of vcore (got a crappy chip) so if i set vcore to around 1.68, which is what it needs, it'll go down to 1.61 and up to 1.71, but since it keeps dipping so low it loses stability, because it's not getting the juice it needs. I also have this problem when system is at stock speeds, but since it doesn't need much vcore at stock speeds it doesn't make any difference. My old PSU (Antec 350w) died on me after i got this system, so i bought a new one (Enermax noisetaker 420w), all my rails are better now, but the CPU vcore is still jumpy like it was before.

I keep hearing i don't need a high power PSU, but it does seem like it. Or maybe it's a problem with my motherboard or something? Both of the PSUs i've had should easily be able to handle my sytem, or so i've heard. Any settings i can make or something that might help out? I've tried different bioses. Cool and Quiet mode is disabled. I could raise the vcore more, but then it would peak at like 1.75, which would be too much.
 
vcore tends to jump around a bit when cpu usage changes, try running seti or folding at home, if you cpu is always at 99% usage vcore might stabalize.
 
I have the same mobo and the same problem. it does fluctuate too much. This with an Antec Tru 550w PSU.

Guess i got lucky my chip does 2.4ghz@ stock volt.

Wow. Didn't know that. And I thought I might of had a problem too.
 
I'm finding out everyone who has this mobo has this problem, that's a bummer.

Yeah i got a bad OC chip unfortunately, and everyone else is getting good ones, i hate that =p
