Description
The Kingston PR10840 is a 4GB memory module engineered for server and high-performance computing environments that utilize the DDR2 memory standard. This module is of the Fully Buffered DIMM (FB-DIMM) type, which incorporates an Advanced Memory Buffer (AMB) chip on the module itself. This buffer isolates the memory controller from the memory chips, allowing for higher densities, increased bandwidth, and improved signal integrity, especially in systems with many memory modules installed. Operating at a speed of 667MHz (PC2-5300), this FB-DIMM provides substantial bandwidth, making it suitable for memory-intensive applications and workloads common in server environments. The module features a 2Rx4 configuration, indicating it is dual-ranked with four memory chips per rank. Dual-rank modules can offer performance advantages in certain scenarios by allowing the memory controller to access data from different ranks concurrently, effectively doubling the number of available memory banks. With a CAS Latency (CL) of 5, the PR10840 balances speed with stability. As an FB-DIMM, it inherently supports ECC (Error-Correcting Code) functionality, which is critical for maintaining data integrity in servers and workstations where system uptime and data accuracy are paramount. This module is designed to meet the rigorous demands of enterprise-level computing, offering reliability and performance for critical operations.
