System-Specific DDR5 Kit

This NEMIX RAM kit delivers 256GB across four 64GB DDR5 modules rated at 6400MHz with CL52 latency. The registered ECC RDIMM design operates at 1.1V using 2Rx4 organisation on a 288-pin form factor. It is built for the SuperMicro GrandTwin A+ Server AS-2116GT-HNTF.

Compatibility and Use Case

Suits administrators expanding memory in the named SuperMicro platform where registered ECC DDR5 is required. Not for desktop boards that accept only unbuffered non-ECC memory, nor for systems limited to lower densities or different pin counts. Buyers needing unregistered DIMMs should look elsewhere.

Deciding Specification

The registered ECC RDIMM interface with 2Rx4 architecture at 1.1V determines fit. Only platforms that explicitly support this module type and voltage will recognise the full 256GB capacity.

Questions about this item

Does the SuperMicro AS-2116GT-HNTF server require a specific BIOS version or CPU generation to recognise the 6400MHz DDR5 RDIMMs?

The kit is validated for the SuperMicro GrandTwin A+ AS-2116GT-HNTF; consult the server manual for any BIOS or CPU requirements before installing the 256GB modules.

Can I mix these 2Rx4 ECC RDIMMs with existing single-rank DDR5 modules already installed in the AS-2116GT-HNTF?

Mixing 2Rx4 registered ECC modules with different rank or speed DIMMs is not recommended; populate all four slots with this matched 64GB kit for stable operation.

How do I confirm the 256GB kit is running at 6400MHz CL52 after installation?

Enter the BIOS or use a system-information tool to verify the memory reports DDR5-6400, CAS latency 52 and the full 256GB capacity across all four slots.
