Exact-match server kit

This 384GB kit contains twelve 32GB DDR5 RDIMMs rated at 6400MHz with CL52 timing and 1.1V operation. It is built for the GIGABYTE MZ23-SU0 motherboard and other systems that require registered ECC memory in a 288-pin form factor.

Registered ECC constraints

Registered architecture buffers the command bus so every slot can be populated at full rated speed, while ECC corrects single-bit errors before they affect data integrity. The DDR5 6400 standard sets the electrical and timing envelope; exceeding it requires motherboard qualification that is not guaranteed by this kit alone.

Plain modules for dense populations

Without heat spreaders the modules sit low enough to clear tight DIMM spacing in 12-slot configurations. The 288-pin RDIMM keying prevents accidental insertion into UDIMM or SODIMM sockets, and the 2Rx8 organization matches the controller expectations for maximum capacity per channel.

Questions about this item

How do I choose between the available kit sizes for this NEMIX RAM DDR5 memory?

This listing provides a single 384GB kit built from twelve 32GB modules; no alternative capacities are offered for this part number.

What does the 6400MHz speed rating mean when the kit is installed in a GIGABYTE MZ23-SU0 motherboard?

The modules run at DDR5-6400 (PC5-51200) with CL52 latency at 1.1V, delivering the rated throughput when the board's memory controller is fully populated with all twelve RDIMMs.

What does the 288-pin RDIMM interface cap in practice for this server memory kit?

The 288-pin Registered DIMM form factor enables full 384GB capacity across all twelve slots while the registered buffer and ECC maintain stability at the rated DDR5-6400 speed.
