Product Description
This Hynix memory module, identified by the SKU HMT151R7AFP4C-G7DB-AA-C, is a 4GB DDR3 Registered DIMM (RDIMM) engineered for server and workstation environments. It operates at a frequency of 1066MHz, corresponding to the PC3-8500 standard, and features a CAS latency of CL7. This combination provides a balance of capacity, speed, and reliability suitable for demanding enterprise applications. The module is configured as 2Rx4, meaning it is dual-ranked with four memory chips per rank. Dual-rank modules can offer performance advantages in certain system architectures by allowing the memory controller to access different ranks concurrently, potentially improving throughput. The RDIMM design includes an onboard register chip that buffers address and command signals, reducing the electrical load on the memory controller and enabling higher memory capacities and improved system stability, which is critical for servers running 24/7. As an ECC (Error-Correcting Code) memory module, the HMT151R7AFP4C-G7DB-AA-C is designed to detect and correct single-bit errors and detect multi-bit errors, thereby enhancing data integrity and system reliability. This feature is essential for mission-critical applications where data accuracy and uptime are paramount. The 240-pin form factor is standard for DDR3 RDIMMs, ensuring compatibility with a wide range of server and workstation motherboards that support this memory technology.
