I have an Asus A7n8x-x and an XP-M 2500+ with the latest bios (1007 I think). In the choices for multiplier, it has some that have 2 listed as one choice, i.e. 7.0x / 15.0x. How do I get it to use the higher of the 2 multipliers for those choices? Every time I choose one of those for the multiplier, it always goes with the lower one.
