Server DDR5 16 GB 6400 MT/s RDIMM

This NEMIX RAM module is a 16 GB DDR5 registered DIMM rated at 6400 MT/s (PC5-51200) with CL52 latency and 1.1 V operation. It uses a 1Rx8 organisation and 288-pin form factor, built with major OEM DRAM chips and ECC protection for data integrity.

For servers needing registered ECC memory.

The RDIMM register and ECC function target server and workstation platforms that require buffered, error-correcting memory. Standard consumer motherboards and laptops cannot use registered modules, so builders of those systems should look elsewhere.

DDR5 6400 MT/s speed grade decides fit

The single specification that determines compatibility is the 6400 MT/s DDR5 data rate; the platform must explicitly support this speed and registered DIMM topology for the module to operate as intended.

Questions about this item

What server memory slot does this 288-pin DDR5 RDIMM fit?

It installs in a standard DDR5 288-pin RDIMM slot on a server motherboard that supports registered ECC memory.

What is the correct orientation when seating this 1Rx8 module?

Align the single key notch on the module with the slot key, press straight down until both retention clips click, and verify the module sits evenly.

How can I tell when this ECC RDIMM should be replaced?

Replace the module if the server logs uncorrectable ECC errors, fails POST memory tests, or shows persistent correctable error counts that exceed the platform threshold.
