is7 vcore fluctuating

I have a 2.4C and am using bios version 13 and i'm using an antec pp352xp power supply (350 watts)

I upped the voltage at around 3.48Ghz to increase the stability, but what i noticed was that the vcore would go down when i load up the CPU, then go back up when the load is removed. can anyone confirm that it's the fault of the PSU? thanks

There's been a lot of talk about that at the abit forums. Abit says it's supposed to work that way, except they're saying it's the other way around (voltages increases dynamically when cpu is loaded). Just another issue (temp is the other one) where abit seems to be giving people the runaround.

IS7 here and same thing here. 3.3v line is actually 3.15 etc.
