Know before you buy
No, this is a Registered DIMM (RDIMM) designed specifically for server motherboards. It is not compatible with standard consumer desktop motherboards that require unbuffered (UDIMM) memory.
ECC (Error Correction Code) detects and fixes data corruption, while the Registered design includes a buffer that reduces electrical load on the memory controller. Together, these features provide the high stability and reliability required for 24/7 server operations.
Mixing memory modules is generally discouraged, especially in server environments. For optimal performance and stability, it is recommended to use identical modules with the same specifications, rank, and capacity across all slots.
No, this module is designed to operate efficiently at 1.1V without a heat spreader. It is intended for use in server chassis that utilize high-airflow cooling systems to manage thermal output.
The 2rx8 structure means the memory is organized into two ranks of chips, which can improve performance by allowing the memory controller to access one rank while the other is refreshing. This configuration is standard for high-capacity server modules to balance speed and stability.
