"One of PW-65E advantages over PW65-D is the increased cache bandwidth - 133Mhz versus 100Mhz. It is also possible for this board to run 133Mhz FSB CPUs without the need of overclocking. The display cache is sustained by 2Mb of 7ns EtronTech memory. A good observation is that 7ns goes to a theoretical 143Mhz which makes PW65-E suitable for overclocking."
