Compatible Server Memory Kit

This NEMIX RAM kit delivers 256GB of DDR5 ECC registered memory in a matched pair of 128GB modules. It is built for Supermicro MBD-X13DGU AI SuperServer motherboards that require registered DIMMs with error correction. The modules operate at 5600MHz with CL46 latency and a low 1.1V supply.

Platform Requirements

Your motherboard must support DDR5 RDIMM modules in a 288-pin form factor and accept 4Rx4 density at the rated speed. Verify that the BIOS revision on the Supermicro board lists this capacity and rank configuration as supported. The system must also provide ECC and registered memory functionality for the kit to operate correctly.

Ideal Use Cases

This kit suits administrators expanding memory capacity in compatible Supermicro AI and HPC servers where registered ECC stability is mandatory. It is not intended for consumer desktop boards that lack RDIMM support or for systems limited to lower maximum capacities per slot. Buyers needing unbuffered or non-ECC DDR5 should select a different product.

Highlights

  • 256 GB total capacity across two 128 GB modules

Questions about this item

Does the 256 GB kit include both 128 GB modules or must the second stick be purchased separately?

The package contains two 128 GB DDR5 5600 RDIMMs for a total of 256 GB; no additional modules are required.

When should I choose the CL46 5600 version instead of the 4800 alternative?

Select the 5600 CL46 kit when the SuperMicro X13DGU motherboard supports the higher data rate, as it delivers greater bandwidth at the same 1.1 V.

What does the 5600 MT/s rating mean once the modules are installed in the SuperMicro X13DGU?

The memory will run at up to 5600 MT/s (PC5-44800) with CL46 latency, providing registered ECC bandwidth for AI and server workloads.
