i tested my system at full load, and hooked osciloscope, here are results

white default 1.125, yellow undervolt 0,93


Spikes and valleys are stronger at bigger volts, thats why he is relatively fine at lower voltages..

But that really depends on PSU & motherboard.

Impressive to see the power coming through the O-scope, I would have expected much cleaner power, though that really isn't too bad. I imagine when you put it through a picky processor doing millions upon millions of calcs a second, its a different story. Wonder what would happen if you were to put a battery in a system..... one of those curiousity things. Don't try to disprove me, I don't care, but 'clean' dc comes from batteries smile.gif

It depends on what he measured. If it was vcore, then nothing would change if you use a battery.

absolutely..
you see what psu i have, its a strong single 12V lane (dont worry, he has clean output) - mobo has 6 phases and OC is not available..
few valleys were at 0.6V !eek.gif peaks up to 1.6V (@ stock volts1,125)

i can only imagine, how nasty would look measurement from cheaper mobo with thuban inserted and high OCed..eek.gif

The only oscilloscopes i have are at school so i can't test it myself. But I was planning on measuring the real volts tomorrow if i find vcore measurement points on this board. I have a feeling there's a big diffrence between real vcore and what cpu-z reports.
