Product Description
This Micron 8GB DDR2 VLP RDIMM, model MT72HVQ1G72PZ-667HZES, is engineered for demanding server applications where space efficiency and robust memory performance are paramount. The DDR2 technology provides a solid foundation for multitasking and running memory-intensive applications, while the 667MHz clock speed ensures rapid data access. The Registered DIMM (RDIMM) architecture incorporates an on-board register to buffer command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in multi-processor systems. The Very Low Profile (VLP) form factor is a key feature, designed to fit within systems with limited vertical clearance, such as high-density blade servers or compact rackmount servers. This allows for increased module density per server, maximizing the total memory capacity within a given chassis. The 4Rx4 configuration signifies that the module is composed of four ranks, each consisting of memory chips organized as 4 bits wide. This multi-rank design can enhance performance by allowing the memory controller to interleave access across different ranks, effectively increasing the overall data throughput. With a CAS Latency of CL5 and operating at the standard DDR2 voltage of 1.8V, this memory module is optimized for reliability and performance in enterprise environments. The Registered ECC (Error-Correcting Code) functionality detects and corrects single-bit errors on the fly, preventing data corruption and system crashes, which is critical for mission-critical server operations. The MT72HVQ1G72PZ-667HZES is a specialized memory solution designed to meet the stringent requirements of modern data centers.
