Server Memory Kit

This NEMIX RAM kit delivers 384GB across eight 48GB DDR5 RDIMM modules rated at 4800MHz PC5-38400 with CL40 latency and 1.1V operation. Registered ECC architecture targets Supermicro H13SSW motherboards that require 288-pin registered DIMMs for full-capacity population.

Upgrade Path

The kit replaces partial or mixed-capacity DDR5 populations that limit total memory or force lower speeds when all slots are filled. The jump is worth it when your workload demands the full 384GB at rated frequency and the board's memory controller expects 2Rx8 registered modules at 1.1V.

Compatibility Check

Verify that your Supermicro H13SSW system manual approves eight 48GB registered ECC DIMMs and confirms the required population order for all slots. Confirm the board accepts 2Rx8 DDR5 RDIMMs at 1.1V CL40 without BIOS limitations on maximum capacity per slot.

Questions about this item

Will these 288-pin DDR5 RDIMMs fit the DIMM slots on my Supermicro H13SSW motherboard?

Yes, the 288-pin registered DDR5 form factor matches the slots on the Supermicro H13SSW and the kit is verified for that board.

What is the correct order to populate the eight 48 GB modules so the server recognises the full 384 GB?

Follow the motherboard manual's DIMM population sequence; the board's memory-controller rules dictate which slots must be filled first for all eight modules to operate at DDR5-4800.

Do these registered ECC modules need any firmware updates or battery-backed maintenance over their service life?

No firmware updates or battery maintenance are required; the modules are solid-state with on-die ECC and registered buffering for the lifetime of the server.
