Product Description
The Hynix HMT351R7EFR8C-RD is a 4GB DDR3 Registered DIMM (RDIMM) module, engineered for enhanced performance in server and workstation environments. As an RDIMM, it features a register chip that buffers command and address signals, reducing the electrical load on the memory controller. This design is crucial for supporting higher memory capacities and ensuring system stability, especially in complex server configurations. This module operates at a faster speed of 1866MHz (PC3-14900), providing increased data throughput compared to standard 1600MHz modules. This makes it suitable for applications that benefit from higher memory bandwidth. The 2Rx8 rank organization indicates two ranks, with each memory chip being 8 bits wide, a common configuration for 4GB DDR3 modules that balances density and performance. With a CAS Latency (CL) of 13, the HMT351R7EFR8C-RD offers a slightly higher latency than CL11 modules but compensates with its increased clock speed. It also includes Error-Correcting Code (ECC) functionality, which is vital for servers and critical workstations to detect and correct memory errors, thereby ensuring data integrity and system reliability. The module operates at the standard DDR3 voltage of 1.5V.
