NEMIX RAM DDR5 4800 192GB 2x96GB ECC RDIMM CL40 1.1V Supermicro H13SSF memory upgrade

192GB DDR5 ECC RDIMM kit for Supermicro H13SSF

This 192GB kit contains two 96GB DDR5-4800 Registered ECC RDIMMs built for the Supermicro H13SSF motherboard. The modules match the board's required 288-pin RDIMM form factor, 2Rx4 rank structure, 1.10V operating voltage and CL40 timing. They are intended for servers that need maximum supported capacity with error correction.

Capacity and headroom at DDR5-4800

Two 96GB modules fill two slots with 192GB total, letting the memory controller run fully populated at the rated 4800 MT/s speed. Registered buffering offloads the controller so every populated slot operates at full capacity. ECC corrects single-bit errors on the fly to prevent silent data corruption. The kit will not work in systems that require UDIMM or SODIMM form factors or that do not support 96GB density per DIMM.

Build quality and daily implications

Modules use major OEM Samsung, Micron or Hynix chips without heat spreaders, relying on server chassis airflow for cooling. The 288-pin RDIMM keying ensures correct insertion orientation in the Supermicro H13SSF slots. Registered architecture adds a clock cycle of latency but enables stable operation with all slots populated. Verify your motherboard manual for approved population order and maximum supported capacity before installation.
