576GB DDR5 5600 ECC RDIMM Kit

This NEMIX RAM kit delivers 576GB of DDR5 5600 memory across twelve 48GB registered DIMMs. Each module runs at 1.1V with CL46 latency and a 2Rx8 organization. The registered ECC design is built for the Supermicro H13SSH-E motherboard and its memory controller requirements.

Suited for max-capacity server builds.

The kit targets administrators who must fully populate the H13SSH-E with registered ECC modules at the board's rated speed. It is not for desktop PCs, workstations that accept only unbuffered DIMMs, or any system that cannot use 288-pin DDR5 RDIMMs.

Straightforward slot installation.

Modules install like any 288-pin DDR5 RDIMM by aligning the key notch and pressing until the latches engage. The main risk is ignoring the motherboard manual's population sequence, which can prevent the system from recognizing the full 576GB or running at DDR5 5600.

Questions about this item

Does the Supermicro H13SSH-E motherboard need all 12 slots filled for this 576GB kit to operate?

The kit contains 12 modules of 48GB each. The motherboard's manual defines the supported population rules and any minimum-slot requirements for full-capacity operation.

Will these registered ECC DDR5 modules work in a board that currently runs unbuffered non-ECC DDR5 DIMMs?

No. This kit uses 288-pin registered RDIMMs with ECC. A motherboard designed for unbuffered UDIMMs cannot accept registered modules, and mixing the two types is not supported.

How can I confirm the kit is running at DDR5-5600 with CL46 timings after installation?

Enter the system BIOS or use an OS-level tool such as dmidecode to verify the reported speed of 5600 MT/s, CAS latency of 46, voltage of 1.10V and that all 576GB are detected.
