Hynix HMT451V7DFR8A-PBT8 4GB DDR3-1600MHz VLP RDIMM 1Rx4 CL11 Memory

Product Description

The Hynix HMT451V7DFR8A-PBT8 is a 4GB DDR3 Registered DIMM (RDIMM) memory module, specifically engineered for server environments where stability, scalability, and data integrity are paramount. Unlike Unbuffered DIMMs (UDIMMs), RDIMMs feature an onboard register chip that buffers command and address signals. This buffering reduces electrical load on the memory controller, allowing for more memory modules to be installed in a system and improving overall memory subsystem stability, especially at higher capacities and speeds. This makes RDIMMs the standard choice for most enterprise-grade servers. This module operates at a speed of 1600MHz (PC3-12800), providing fast data transfer rates essential for demanding server workloads. The CAS Latency (CL) is CL11, which is a typical latency for DDR3 memory operating at this frequency. The organization of 1Rx4 indicates a single rank of memory chips, where each chip is 4 bits wide. This configuration is common for RDIMMs and contributes to the module's overall performance and density characteristics. Registered DIMMs inherently support ECC (Error-Correcting Code) functionality, although the specific implementation and level of correction depend on the server's memory controller. ECC memory is critical in server applications as it can detect and correct common types of internal data corruption, preventing system crashes and data loss. The standard operating voltage for DDR3 memory is 1.5V. The VLP (Very Low Profile) designation, often associated with RDIMMs, suggests a shorter module height, which can be beneficial in dense server chassis with limited vertical clearance.
