I'm currently running prime95, stress testing my cpu. In my bios, I have my vcore set to 1.775, but MBM is reading that currently, it's at 1.79(not a *huge* deal), the lowest it's been is 1.73, and the highest is 1.82.

My PSU is an antec true power 430w, and my motherboard is an asus a7n8x PCB rev 2.0. I've read about the PSU mods that I can do, but will they help to stabilize core voltage? If not(or even if so), what else can I do?

I would keep a close eye on the PSU. As long as the voltage on the rails 3.3v, 5v, and 12v lines, stay stable, it should be okay. If your rails start dipping and spiking, get a new PSU.

Voltage reading fluctuations can also be bios problems.

I have had boards that seem to fluctuate a LOT and a bios update fixed it.

Mine run pretty stable but, mine run off a battery backup that has AVR too so the incoming power stays clean and stable.

Just something to keep in mind, is that the voltages you are seeing in MBM are NOT the PSU values, but rather the outputs of the voltage regulators on the MB !
If you want to check the outputs of the PSU yer gonna have to use a multimeter for that !

Bios is latest revision. Rails are all low(by a small small amount), but rock solid. In-fact, the 12v rail hasn't changed in the past 2 hours.
