Just got a 3800+X2, vcore is fluctuating, is this normal??

See title, the mobo is an asus A8N-E, power supply is an Antec TruePower 2.0 430w. Performance seems to be stable, but in CPU-Z i noticed the vcore and cpu speed fluctuating, albeit slightly. is this normal?

yes, thats normal, the voltage does fluctuate a little due to inherent variation of input mains power, the way the PSU regulates it and the way the motherboard serves it up to the cpu.
Also the sensors used to monitor said voltage also fluctuate a little.

As a general rule (very general), expect to se a +/- 0.01 to 0.05v fluctuation in ones core voltage from whatever is standard.
if it varies by more than 0.05v under steady cpu load, or changes by more than 0.05v when going from full load to idle you may have a problem, either poor input power, a bad psu, or poor motherboard voltage regulation.

same with cpu mhz measurements... depending on method of measurement it can vary by quite a few Mhz.

i wouldnt worry

ok, thanks, they are quite within that range (~phew~)
