Is there an easy way to adjust the Vcore on this board or do I just use the +5%, +7.5%, +10% via the bios? BTW while I'm at stock speeds CPU-Z still shows me at 1.7Vcore. Why is that? The barton 2500 is suposed to be 1.65V. Do I need a better power supply or is my board just stock on some form of auto?
