The only way of you overclocking throug hthe BIOS is if u download a certain BIOS and up the FSB. Even if you do this, you sitll only have choices of 138, 150, and 166. To change the voltage/multiplier, you're going to do it via bridges on the chip. However, I've ran my 1.4birdy @ 1.57 (10.5x150) rock stable at cas2.5 fast time settings. If you wan't to save money, get this. If you want to overclock, don't. If you want something in between, get another board.
