Q13. 點解我用DDR-2 667, 係CPU-Z又睇到佢只係行333? 係唔係間鋪呃我?
A13. 正常. DDR 係 Double Data Rate, 333係單向速度, 雙向就當然X2, 行667啦
DDR2 nothing about direction etc.
DDR already represent the data transfer when it rise and fail on the clock cycle.
DDR2 is double the bus (external to chipset/NB) of ddr. So no internal up on the ram clock, but, the "output" doubles.... |
