Server-grade memory kit

This kit supplies 384 GB of DDR5 memory across sixteen 24 GB registered DIMMs. It is built for servers and workstations that require error-correcting, registered modules running at 6400 MT/s.

Registered DIMM constraint

Registered DIMMs add a register between the memory controller and the DRAM, which limits use to platforms that support registered memory. Standard desktop and consumer motherboards cannot accept these modules.

2Rx8 organisation

Each module uses a dual-rank 2Rx8 layout, which determines how the memory controller addresses the chips. Buyers must verify that their server platform supports this rank configuration at the full 6400 MT/s speed.

Questions about this item

Should I choose the 16-module kit or buy smaller kits to reach 384GB?

The 16 x 24GB kit delivers the full 384GB in matched modules, ensuring identical rank and timing across all slots for stable server operation.

What does the 6400MHz rating mean once installed in a server?

The modules run at DDR5 6400 (PC5-51200) with CL52 latency at 1.1V, providing the rated bandwidth when the platform supports that speed.

How does the 288-pin ECC RDIMM interface limit real-world use?

The 288-pin registered DIMM format with ECC only fits server motherboards that accept DDR5 RDIMMs; it will not work in standard desktop boards.
