NEMIX RAM
256 GB DDR5 5600 ECC registered server memory kit with eight 32 GB modules at CL46 and 1.1 V for SuperMicro B13SEG motherboards
This 256GB kit comprises eight 32GB DDR5 registered DIMMs built for the SuperMicro B13SEG platform. It targets IT professionals who need validated, high-density memory for server and workstation workloads. Each module is stress-tested for stability in mission-critical environments.
The modules run at DDR5 5600 (PC5-44800) with CAS latency 46 and a 1.10V operating voltage, providing ample throughput for virtualization, database and AI inference tasks. Capacity scales to 256GB across eight slots; beyond that the board’s DIMM count limits further expansion.
The single specification that decides fit is the registered ECC 2Rx8 288-pin DDR5 RDIMM form factor. Only systems accepting registered DDR5 ECC RDIMMs can use this kit; consumer boards or unbuffered DDR5 slots will not work.
