Re: CPU Vcore...
1.5v isn't dangerous, as long as the temperatures are low enough, to handle it. So really...voltage is limited to the temperatures of your CPU. If you're at 1.5v, for example....and your temperatures are let's say, 40c idle/50-54c load. You can increase a little, to get that extra speed or to get more stability, if your overclock isn't.
I think it's best to disable anything you're not using, while overclocking. Such as unused SATA ports, RAID, and anything you don't use...floppy drive. This prevents various conflicts, that might happen.
