I'm using an old Socket 7 board (An Acer V75M for an IBM Aptiva 2170) and an AMD K6-3 450. It's Vcore is supposed to be 2.4v. I tried it at 2.3, but the system would spontaneously reboot just as it was loading the desktop. I then crank it up to 2.8 and it seems fine, but I fried one of these boards (and a K6-2 450) a few weeks ago by having too high a Vcore. I can't set the Vcore to 2.4v because the board's dip switches only allow me to choose from 1.7, 2.2, 2.3, 2.8, 2.9, and 3.3v. Is there any program or method out there that lets you change the Vcore some other way, even in software?
