Hynix HMT42GR7BMR4C-G7D7 16GB DDR3-1066MHz RDIMM 4Rx4 CL7 Memory

Product Description

This Hynix memory module, SKU HMT42GR7BMR4C-G7D7, provides a substantial 16GB capacity within the DDR3 SDRAM standard. It is a Registered DIMM (RDIMM), which is essential for server environments as it includes a register that buffers command and address signals, reducing the electrical load on the memory controller. This allows for greater memory capacity per channel and improved system stability, crucial for mission-critical applications. The module is designed for compatibility with server motherboards that support DDR3 memory. The module operates at a frequency of 1066MHz (PC3-8500R), offering a balance between capacity and speed for certain server workloads. The CAS latency is CL7, which is relatively low for DDR3 memory, indicating a quick response time to data requests. A key characteristic of this module is its 4Rx4 configuration, meaning it is quad-ranked with each rank utilizing x4 DRAM chips. Quad-rank modules can offer performance benefits through advanced rank interleaving techniques, allowing the system to access data from multiple ranks concurrently, potentially increasing bandwidth and efficiency in specific scenarios. As a server-grade component, the HMT42GR7BMR4C-G7D7 includes Registered ECC (Error-Correcting Code) functionality. ECC memory is vital for maintaining data integrity by detecting and correcting memory errors, which is a standard requirement in enterprise computing to prevent data corruption and ensure system reliability. This 16GB quad-rank RDIMM is suitable for servers and workstations that require high memory density and robust error correction capabilities, particularly those optimized for workloads that can leverage its specific rank configuration.
