Hynix HMT31GR7BFR4A-H9D2-AE 8GB DDR3-1333MHz RDIMM 2Rx4 CL9 Memory

Product Description

The Hynix HMT31GR7BFR4A-H9D2-AE is a high-quality 8GB memory module designed for server and workstation environments. As a DDR3 Registered DIMM (RDIMM), it incorporates a register chip that buffers command and address signals, reducing electrical load on the memory controller. This feature is crucial for systems that utilize a large number of memory modules, enhancing signal integrity and allowing for higher memory capacities and improved stability. The 'Registered' aspect also means it is typically not compatible with standard desktop motherboards, which usually require Unbuffered DIMMs (UDIMMs). This module operates at a speed of 1333MHz, corresponding to a bandwidth of PC3-10600. It features a CAS Latency (CL) of 9, which indicates the number of clock cycles required to access a particular column of data. The 2Rx4 designation signifies that it is a dual-rank module with a memory chip organization of x4 (4 bits wide per chip). Dual-rank modules can offer performance benefits in certain scenarios by allowing the memory controller to access different ranks independently, effectively doubling the number of available memory banks. Furthermore, this Hynix RDIMM supports Error-Correcting Code (ECC) functionality. ECC memory can detect and correct common types of internal data corruption, significantly improving data reliability and system stability. This makes it an indispensable component for mission-critical applications where data integrity is paramount, such as in servers handling financial transactions, scientific research, or large-scale data analysis. The standard voltage for DDR3 is 1.5V, ensuring compatibility with DDR3-compatible server platforms.
