Conclusion: One area that this board really excels in is stability. For over a month now, we have been running our P3-450 @ 558 MHZ. in various other BX boards. In order to do this, we had to boost the core voltage of the CPU to at least 2.1V. The MS-6163 Pro handled 558 MHz. and let our overworked and under paid CPU stay at default voltage. This was a great testament to its design and quality.
