Hynix HMT42GR7AFR4C-PBT8AD 16GB DDR3-1600MHz RDIMM 2Rx4 CL11 Memory

Description

The Hynix HMT42GR7AFR4C-PBT8AD is a high-capacity 16GB DDR3 Registered DIMM (RDIMM) module, engineered for demanding server and workstation applications. Operating at a speed of 1600MHz (PC3-12800), it provides ample bandwidth for data-intensive tasks. The RDIMM format includes an onboard register that buffers data between the memory controller and the DRAM chips, reducing electrical load on the memory controller and allowing for higher memory capacities and improved stability in systems with many memory modules. This module features a 2Rx4 configuration, meaning it is dual-ranked with four memory chips per rank. Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to access different ranks independently. The CAS Latency (CL) of 11 indicates the number of clock cycles required for data access, providing a balance between speed and reliability for DDR3 memory. The standard 1.5V operating voltage is typical for DDR3 modules. Crucially, this is a Registered ECC (Error-Correcting Code) module. ECC functionality detects and corrects single-bit memory errors, significantly enhancing data integrity and system reliability, which is essential for mission-critical server operations. The 'PBT8AD' suffix likely denotes specific manufacturing or testing specifications. It is vital to ensure system compatibility, as RDIMMs are not interchangeable with UDIMMs (Unbuffered DIMMs) and require server-class motherboards that support registered memory.
