512GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit provides 512GB of DDR5 5600 registered ECC memory in a matched set of four 128GB modules. It is built for Supermicro B13SEE-CPU-25G motherboards and similar enterprise platforms that require registered DIMMs with error correction. The modules operate at 1.1V with a CAS latency of CL46 and a 4Rx4 rank configuration.

Suited for registered-DIMM servers only

This memory fits servers and workstations that accept 288-pin DDR5 RDIMMs with ECC and registered buffering. It will not work in consumer desktop boards, laptops, or any system that requires unbuffered UDIMMs or non-ECC modules. Buyers needing standard desktop memory or SODIMM form factors should look elsewhere.

DDR5 5600 RDIMM compatibility

The decisive specification is the DDR5 5600 RDIMM registered ECC interface; the motherboard must explicitly support 288-pin DDR5 registered DIMMs at this speed and voltage. Verify the platform's qualified vendor list for 4Rx4 128GB modules before purchase.

Questions about this item

Should I pick the 512GB kit or look for a different capacity?

This kit provides 512GB total across four 128GB modules. Choose it when your Supermicro B13SEE-CPU-25G motherboard has four available DDR5 RDIMM slots and your workload needs that density.

What does the 5600 speed rating deliver once installed?

The modules run at DDR5 5600 (PC5-44800) with CL46 latency at 1.10V. Actual throughput depends on the CPU memory controller and BIOS configuration on the Supermicro platform.

How does the 288-pin ECC RDIMM interface limit what I can do?

The 288-pin DDR5 RDIMM form factor with ECC and registered buffering only fits compatible Supermicro server boards. It will not work in consumer desktop or laptop slots.
