384GB DDR5 6400 ECC RDIMM kit

This NEMIX RAM kit provides 384GB total capacity across four 96GB DDR5 6400 Registered ECC RDIMMs. It is built for the Supermicro H13SST-G motherboard and runs at 1.1V with CL52 latency. The modules use a 2Rx4 rank structure and 288-pin form factor for full-slot population at rated speed.

For Supermicro H13SST-G DDR5 servers

Suits administrators upgrading a Supermicro H13SST-G system that requires Registered ECC DDR5 RDIMMs and supports 96GB per slot. Not for systems that accept only unbuffered UDIMMs, SODIMM form factors, or lower DDR generations. Also unsuitable where the memory controller cannot address 96GB density per module.

96GB 2Rx4 DDR5 6400 Registered ECC

The single specification that determines fit is the 96GB 2Rx4 DDR5 6400 Registered ECC RDIMM profile at 1.1V. The Supermicro H13SST-G memory controller must support this exact density, rank, voltage and timing for the kit to be recognised at full capacity and operate at its rated 6400 MT/s.

Questions about this item

Does the 384GB kit contain four 96GB modules or do I need to buy additional DIMMs?

The kit includes four 96GB DDR5 6400 CL52 2Rx4 registered ECC RDIMMs for a total of 384GB; no extra modules are required.

Why choose the 2Rx4 96GB registered ECC version instead of a UDIMM or lower-capacity kit?

The Supermicro H13SST-G requires 288-pin registered RDIMMs; this 2Rx4 96GB ECC kit matches the board's population rules and runs at the rated 6400 MT/s.

What does the DDR5 6400 CL52 rating mean once the memory is installed in the server?

The modules operate at 6400 MT/s with CAS latency 52 at 1.1 V, delivering the exact speed and timing the motherboard's memory controller expects when fully populated.
