DeezTech heeft een review geschreven van een P3-550E die hij met behulp van een VIA Apollo Pro 133A mobo op 825MHz (5.5 x 150MHz FSB) draait. De 550E kan dus toch wel gezien worden als een vrij redelijke opvolger van de befaamde Celly 300A:
Originally we used an ABIT BE6-II 440BX based board for our over clocking experiments. The BE6-II is an awesome overclockers board boasting bus speeds up to a whopping 200 MHz, along with core and I/O voltage adjustments. Unfortunately though, the BE6-II proved not to be the best board for this particular application. We were able to over clock the processor itself to unholy speeds of 840+ MHz. The problems we found didn't stem from the processor stability, but rather from the high AGP speeds that were forced to deal with. Both our TNT2 and V3 boards were not able to handle the 116+ MHz AGP speeds that we were throwing at them. So, we went out and got the VA6 which is the Apollo 133 based motherboard.from ABIT. The main advantage of this board was the ability of the chipset to cut the AGP speeds by one half. This particular ability allowed us to bring our 550E to a stable 825 MHz. Unfortunately, because this particular motherboard doesn't support bus speeds higher than 150 MHz, 825 MHz was the highest we could bring the processor. This speed is by no means anything to laugh at. We should be getting the ABIT CH6 i820 based board in the near future, and then we are going to revisit our 550E for some more benchmark action. The only complaint we had with the VA6 was the Via Chipset's slower nature which became quite evident in our Sandra 2000 benchmarks.
