Here's where the AOpen AX5T-3.1 really shines, its ability to run the Pentium MMX at 291MHz, without raising the core voltage above 3.0v is an amazing accomplishment on the part of AOpen.  The increased stability over revision 2 of the AX5T is achieved by an implementation of a switching voltage regulator instead of the former Linear Voltage Regulator which was present on the AX5T (and the AP5T - AT version).  Basically, the motherboards listed here have gone above and beyond the call of duty to be faithfully dubbed as Die Hard Overclockers, the perfect match for a Pentium MMX.
