Thank you, I assumed that was what was going on but wanted to be sure before i 
did an install on it lest it die half way through.

If you have cpu frequency scaling options enabled (in kernel[1]) and
Cool'n'Quiet[2] in BIOS, that should be normal.

If it increases with load the regulator is working properly. The
higher voltage is needed to induce a higher current slew rate, i.e.
how fast the electrons accelerate, i.e. chip frequency.

[gentoo-user] Vcore unstable?

[mad.scientist.at.large]

i have a machine i just put lm sensors etc. on.  xsensors shows "Vcore" 
fluctuating between 1.12 and 1.3v.  stays at 1.12V when idling but increases 
with load.  Is this remotely normal behavior for an athlon chip in a desk top?  
It's either some sort of throttling or the Vcore power supply is failing, 
obviously i'd like to know which.  If it's the power supply i can likely fix it 
if it needs to be fixed.  Also occurs to me that xsensors could be usefull 
tracking down intermittent issues.  I used it to monitor a power supply i 
wasn't sure about for about a week and it stayed nice.
