8PE667 series - Why cannot my DDR 333 be recognized correctly as 333Mhz but 266Mhz in 8PE667(8GE667) series mother board?
Based on Intel 845PE/GE chipset specifications, whether DDR333 can be supported appropriately depends on the CPU type you use. DDR 333 can be recognized correctly only when you use a FSB533 CPU. If you use a FSB400 CPU, then it's very possible that it can be recognized as 266Mhz.
