IBM 33L3281-RFB 256MB PC1600 ECC SDRAM RDIMM 33L3281-RFB

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.

Features & Benefits:

• These memory data transfer rate enhancements translate into 6 to 8 percent improvements for typical applications. In some server applications where large contiguous blocks of data are transferred, significantly greater performance improvements will be achieved.
• Chipkill memory technology increases overall system and data reliability and corrects many soft memory errors automatically without any software intervention.
