The HMT42GR7BMR4A-G7T7 is a DDR3 registered ECC memory module from Hynix Semiconductor, specifically designed for servers and workstations requiring high reliability and data integrity. This module features a registered design, which includes a register between the DRAM modules and the memory controller. This reduces the electrical load on the memory controller, allowing for increased memory capacity and improved stability, especially in systems utilizing multiple modules.

Applications:

• Servers
• High-performance workstations
• Data centers
• Virtualization platforms

Features:

• DDR3 Technology
• Registered ECC DIMM (RDIMM)
• Module Size: 16GB (1 x 16GB)
• Module Rank: 2Rx4
• Speed: PC3-12800 (DDR3-1600)
• CAS Latency: CL11
• Voltage: 1.35V (Low Voltage)
• 240-Pin DIMM

Benefits:

• Improved System Stability: The registered design improves signal integrity and reduces the load on the memory controller, resulting in a more stable and reliable system, particularly when using multiple modules.
