Description
The Kingston KTD-WS667LP/4G-G is a 4GB memory kit designed for server and workstation platforms that utilize DDR2 Fully Buffered DIMM (FB-DIMM) technology. This kit includes two 2GB FB-DIMM modules, totaling 4GB of memory capacity. FB-DIMMs were a key technology for scaling server memory capacities by incorporating an Advanced Memory Buffer (AMB) chip on each module, which isolates the memory controller from the electrical load of the memory chips. Each 2GB module in this kit operates at a frequency of 667MHz, corresponding to a PC2-5300 data transfer rate, and features a CAS Latency (CL) of 5. The standard operating voltage for DDR2 FB-DIMMs is 1.8V. These modules are ECC (Error-Correcting Code) Registered DIMMs (RDIMMs), providing critical data integrity features necessary for server environments. The registered design helps improve signal integrity and allows for higher memory densities. The '2Rx4' designation indicates that each 2GB module is dual-ranked, with each rank composed of x4 memory chips. Dual-rank configurations can enhance memory performance by allowing the memory controller to interleave operations between ranks. This Kingston kit is a suitable choice for upgrading or maintaining memory in compatible servers and workstations that require DDR2 FB-DIMM RDIMMs, offering a balance of capacity, performance, and reliability for demanding enterprise applications.
