NEMIX RAM MR38400-9624K8 768GB (8x96GB) DDR5 4800 CL40 2Rx4 ECC RDIMM Supermicro H13SSL-N memory upgrade

Supermicro H13SSL-N DDR5 kit

This 768GB kit contains eight 96GB DDR5-4800 registered ECC RDIMMs built for the Supermicro H13SSL-N motherboard. It targets administrators who need the maximum supported capacity in a single validated package. The modules run at 1.1V with CL40 latency and a 2Rx4 organization. Each DIMM uses major-brand DRAM and carries a lifetime replacement warranty.

Verify board population rules

Before ordering, consult the H13SSL-N manual for approved DIMM population order and maximum capacity per channel. The board requires 288-pin registered RDIMMs; UDIMMs or SODIMMs will not function. Confirm that your BIOS revision supports the full 768GB configuration across all eight slots. No heat spreaders are included, so ensure chassis airflow meets the vendor's thermal guidelines.

Replaces partial or mixed-capacity sets

This kit replaces incomplete or mismatched DDR5 RDIMM populations that limit total memory or force reduced speeds. The jump is worth it when workloads demand the full 768GB at rated 4800MT/s with ECC protection active. It is not for systems that only accept unbuffered memory or that cap registered DIMM capacity below 96GB per slot.
