Hynix HMT351R7CFR8C-RD 4GB DDR3-1866MHz RDIMM 2Rx8 CL13 Memory

Product Description

The Hynix HMT351R7CFR8C-RD is a 4GB DDR3 Registered DIMM (RDIMM) module, engineered for server and high-performance computing environments. It operates at a high frequency of 1866MHz, corresponding to the PC3-14900 specification, which provides significantly increased memory bandwidth compared to lower DDR3 speeds. This makes it suitable for demanding applications that require rapid data access and processing, such as virtualization, large database operations, and scientific simulations. The module features a CAS Latency (CL) of 13. While this latency is higher than some other DDR3 modules, the 1866MHz clock speed ensures a substantial throughput. The 2Rx8 configuration indicates that the module is dual-ranked, with each rank utilizing x8 (8-bit) DRAM chips. Dual-rank modules can offer performance advantages in certain system architectures by allowing the memory controller to interleave operations between the two ranks, potentially improving efficiency and bandwidth utilization. As an RDIMM, this memory module includes an onboard register that buffers command and address signals. This buffering reduces the electrical load on the memory controller, enabling systems to support a greater number of memory modules and achieve higher total memory capacities. RDIMMs also typically incorporate ECC (Error-Correcting Code) functionality, which is critical for server environments as it detects and corrects single-bit memory errors, thereby enhancing system stability and data integrity. The module operates at the standard DDR3 voltage of 1.5V.
