Question : Problem: Need guidance on all the voltage settings on AOD Tool...

Just got a new Phenom II 720 BE for my Asus M3A78-T (790GX) MB and trying to overclock it.  I am using the AMD OverDrive Tool and there are a bunch of voltage options I don't undertsand:

NB VID Voltage
DDR Voltage
NB Voltage
HT Voltage
SB Voltage
SidePort Voltage

I am looking for the best voltages to set these at.  Right now I am running the CPU at 17.5 x 206 x 1.475volts to get a stable 3.6 ghz.  I could go higher but this is stable and I am happy.

My NB is running at 2000.  Would it be safe to kick that higher?  I am running just some DDR2 800 Ram (4 gigs).  Any ideas on overclocking the NB safely?  I don't see an option for that in AOD, may have to go to Bios.

*Note - when I OC in AOD, it stays stable, but if I turn AOD off and use the exact same OC in Bios, I get BOD every time.  Why is that?  I have always heard that Bios OC  is better, but seems buggy to me.

CPU-Z's voltage readouts aren't always quite correct. To get more precise insight into your system's health, you'll want to install your mobo maker's system monitoring application, which is usually included on your motherboard's driver CD.
