Hynix HMT31GR7BFR4A-H9D7-AB 8GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Product Description

The Hynix HMT31GR7BFR4A-H9D7-AB is an 8GB DDR3 Registered DIMM (RDIMM) memory module, specifically engineered for server and high-end workstation environments where stability, reliability, and large memory capacities are critical. This module operates at a speed of 1333MHz, corresponding to the PC3-10600 standard, providing ample bandwidth for demanding server workloads. The CAS latency is rated at CL9, which is typical for DDR3 modules of this speed and rank configuration. As a 2Rx4 module, it features dual ranks, each with a 4-bit data width. The 'Registered' aspect signifies that the module includes a register chip that buffers the command and address signals between the memory controller and the DRAM chips. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed in a system and improving overall signal integrity and stability, especially in systems with many memory slots. Crucially, this Hynix RDIMM supports ECC (Error-Correcting Code) functionality. ECC memory is essential in server environments as it can detect and correct common types of internal data corruption, thereby preventing system crashes and data loss. The HMT31GR7BFR4A-H9D7-AB is a robust choice for upgrading or populating memory in compatible server platforms that require the performance and reliability of DDR3 ECC RDIMMs.
