NEMIX RAM 64GB DDR5 6400 registered server module

This NEMIX RAM module provides 64GB of DDR5 6400 memory in a single 288-pin ECC RDIMM. It operates at 1.1V with a CAS latency of 52 and a 2Rx4 rank configuration. The kit is built for server platforms that require registered DDR5 6400 DIMMs.

Suits servers needing registered ECC DDR5 6400

This module fits systems designed for DDR5 6400 registered ECC RDIMMs. It is not for desktop PCs or workstations that accept only unbuffered memory. Buyers whose platforms require a different speed, voltage, or form factor should verify compatibility before purchase.

Deciding spec: DDR5 6400 registered ECC RDIMM

The single specification that determines fit is the DDR5 6400 registered ECC RDIMM standard. Only motherboards and CPUs qualified for this exact memory type will support the module. Confirm the platform documentation calls for DDR5 6400 registered DIMMs before ordering.

Questions about this item

Will this 288-pin DDR5 RDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR5 RDIMM form factor, so it fits any server DIMM slot designed for DDR5 registered memory.

What is the correct way to seat this 64GB DDR5 6400 module during installation?

Align the notch with the slot key, press straight down until both side latches click, and verify the 1.1V registered module is fully seated before powering on.

How do I know when this ECC RDIMM needs replacement?

Monitor system logs for corrected ECC errors; a rising count signals the 2Rx4 Samsung, Micron or Hynix chips are degrading and the module should be swapped.
