Based on FSB frequency, the DDR DRAM has 200MHz, 266MHz and 333MHz three types of working frequency. Because DDR
DRAM data bus is 64-bit, it provides data transfer bandwidth up to 200x64/8=1600MB/s, 266x64/8=2100MB/s and
333x64/8=2700MB/s in these current three DDR DRAM. Therefore, the PC-1600 DDR DRAM is working with 100MHz,
PC-2100 DDR DRAM is working with 133MHz and PC-2700 with 166MHz FSB frequency.
