PC3200
PC2-3200 is a memory bar that consists of DDR2-400 memory modules. The data transfer rate of 3200 MB/s results from the specified clock frequency of 400 MHz and the memory bus width of 64 bits, respectively 8 bytes. The clock frequency is already the doubled clock rate of the Front Side Bus ( FSB) of 200 MHz due to Double Date Rate( DDR).
The DDR2 memory bars are DIMM modules and have a contact strip with 240 pins.
