The HMT42GR7BMR4C-G7D7 is a DDR3 registered ECC memory module manufactured by Hynix Semiconductor. This memory module is designed for use in servers and workstations that require high levels of reliability and data integrity. The registered design includes a register between the DRAM modules and the system's memory controller, which reduces the electrical load on the memory controller and allows for greater memory capacity and improved stability, especially in systems with multiple modules installed.

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:

• Enhanced System Stability: The registered design improves signal integrity and reduces the electrical load on the memory controller, contributing to a more stable and reliable system, especially with multiple modules.
• Superior Data Integrity: ECC (Error-Correcting Code) detects and corrects single-bit memory errors, preventing data corruption and ensuring accurate data processing.
• Improved Performance: DDR3 technology offers faster data transfer rates compared to previous generations, resulting in improved application performance and overall system responsiveness.
• High Memory Capacity: 16GB module allows for larger amounts of data to be stored in memory, enabling the system to handle more demanding applications and workloads.
• Lower Power Consumption: Operates at 1.35V, resulting in lower power consumption and heat dissipation compared to standard voltage DDR3 modules.
