CPU:RAM = 4:3
CPU:RAM = 266.67MHz(FSB 1066.67MT/S):200MHz(DDR2-400)
CPU:RAM = 333.33MHz(FSB 1333.33MT/S):250MHz(DDR2-500) <- OC
FSB OC、DDR2也沒有剛好可用的RAM(要買667降500跑)

CPU:RAM = 5:4
CPU:RAM = 266.67MHz(FSB 1066.67MT/S):213.33MHz(DDR2-426)
CPU:RAM = 333.33MHz(FSB 1333.33MT/S):266.67MHz(DDR2-533) <- OC
FSB OC、DDR2剛好有滿足的規格
