33L3283 - IBM 512MB DDR-200MHz PC1600 ECC Registered CL2 184-Pin DIMM 2.5V 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.
