NEMIX RAM
A 32 GB dual-channel kit of 4800 MHz DDR5 ECC registered RDIMMs built for SuperMicro SYS-211SE servers
This 32 GB kit contains two 16 GB DDR5 4800 ECC RDIMM modules built for the SuperMicro SYS-211SE IoT SuperServer. Registered buffering and on-die ECC protect data integrity in always-on server workloads. The 1.1 V operating voltage matches the platform specification.
Registered DDR5 modules keep signal quality stable across all ranks during continuous read-write cycles typical of database or virtualization tasks. ECC corrects single-bit errors on the fly without halting the system. CL40 latency and PC5-38400 bandwidth serve steady throughput rather than burst speed.
Each module uses the standard 288-pin DDR5 RDIMM layout with 1Rx8 organization, fitting the SYS-211SE memory slots directly. No heat spreader is fitted, allowing tight spacing in the 1U chassis airflow path. Samsung Micron or Hynix major OEM chips are used throughout the kit.

Each 16 GB module operates at 1.10 V, the standard voltage for DDR5 4800 RDIMMs, keeping power draw low during all-day operation.
Yes, the kit contains two 288-pin DDR5 RDIMMs that must be installed in registered DIMM slots on the SYS-211SE board.
The modules match the system's DDR5 4800 specification, so they can populate remaining slots alongside identical-speed registered DIMMs.
