Description
The HP 661807-B21 is a high-performance 8GB DDR3 Registered DIMM (RDIMM) memory module, specifically engineered for enterprise-level servers. Operating at a speed of 1333MHz (PC3-10600), this module provides substantial bandwidth for demanding server workloads. The RDIMM design incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-processor systems. This memory module features ECC (Error-Correcting Code) functionality, which is essential for server environments. ECC memory can detect and correct common types of internal data corruption, significantly reducing the likelihood of errors that could lead to system crashes or data loss. The 2Rx4 designation indicates that it is a Dual Rank module with a memory chip organization of x4, which can further enhance performance by allowing the memory controller to access different banks of memory more efficiently. With a CAS Latency (CL) of 9, the 661807-B21 offers a good balance of speed and responsiveness for server applications. This 8GB DDR3 RDIMM is a reliable and robust component designed to meet the stringent requirements of modern data centers, ensuring system stability, data integrity, and optimal performance for critical business operations.
