Product Description
The Hynix HMT42GR7MFR4A-H9 is a high-capacity 16GB memory module designed for server and workstation environments that demand reliability and performance. Operating at DDR3 speeds of 1333MHz, this module provides ample bandwidth for demanding applications and multitasking. The 'R' in RDIMM signifies that it is a Registered DIMM, which includes a register chip that buffers command and address signals, reducing electrical load on the memory controller and allowing for higher memory capacities and greater stability in multi-processor systems. This module features a 2Rx4 configuration, indicating it is dual-rank with four data bits per rank. Dual-rank modules can offer performance benefits by allowing the memory controller to access different ranks independently, improving efficiency. The CL9 latency rating specifies the timing characteristics, with lower numbers generally indicating faster response times. The 'VLP' designation stands for Very Low Profile, meaning the module has a reduced height compared to standard DIMMs, which is crucial for installations in densely packed server chassis or systems with limited vertical clearance, such as blade servers or 1U rackmount servers. Upgrading server memory with modules like the HMT42GR7MFR4A-H9 is essential for optimizing performance in virtualized environments, database operations, and complex computational tasks. Its combination of high capacity, registered architecture, and low profile design makes it a versatile choice for a wide range of enterprise-grade hardware. Ensuring compatibility with the server's motherboard and existing memory configuration is vital before installation.
