33L3281 - IBM 256MB DDR-200MHz PC1600 ECC Registered CL2 184-Pin DIMM Memory Module

This memory option features a new high-speed, double data rate (DDR) SDRAM Registered DIMM that enables the memory data transfer rate to increase without increasing the system processor front-side bus clock speed. This double data rate is accomplished by delivering data on both the rising and falling edge of the processor clock signal once the data transfer begins. This will enable the doubling of the memory transfer rate for the PC100 to 200MHz without increasing the 100MHz front-side bus clock speed. This option features two-way memory interleaving that expands the memory bandwidth and improves the system's overall performance.
