NEMIX RAM 1TB 8x128GB DDR5 4800 CL40 1.1V 2Rx4 RDIMM Supermicro H13SSH memory upgrade

Purpose-built server kit

This 1 TB kit contains eight 128 GB DDR5 RDIMMs tuned for the Supermicro H13SSH motherboard. Registered ECC architecture lets every slot run fully populated while correcting single-bit errors on the fly. System builders who need exact-rank compliance for production workloads will find the modules recognised at rated speed without manual tuning. It is not for desktops or boards that accept only unbuffered memory.

Build and connectors

Each module uses the 288-pin RDIMM form factor with a 2Rx4 organisation and operates at 1.1 V. The registered design buffers address and command signals so the memory controller stays stable across all populated channels. No heat spreaders are fitted, so airflow in dense chassis must be sufficient for sustained loads. Buyers who require passive cooling accessories or low-profile clearance should verify their chassis specifications first.

Deciding specification

The kit runs at DDR5 4800 with CL40 latency, matching the PC5-38400 data rate the H13SSH memory controller expects. Population rules for this platform are strict; the manual defines supported capacities per channel and the required installation order. Deviating from that order can prevent the system from booting or limit usable capacity.
