32GB DDR5 6400 ECC RDIMM

This 32GB DDR5 6400 registered DIMM delivers error-correcting memory for compatible Supermicro servers and workstations. It operates at 1.10V with CL52 latency and a 2Rx4 organization. The module uses major OEM chips from Samsung, Micron or Hynix and carries part number MR51200-324K1.

Registered ECC for Supermicro Platforms

The stick suits administrators upgrading Supermicro X14SBM-TP4F or similar platforms that require registered ECC DDR5 6400 memory. It is not for consumer desktops, laptops or any system that accepts only unbuffered non-ECC modules. Builders needing unregistered memory or a different speed grade should look elsewhere.

DDR5 6400 PC5-51200 Registered Specification

The decisive specification is the DDR5 6400 PC5-51200 registered ECC standard with 288-pin RDIMM form factor. Only motherboards qualified for this exact speed, voltage and registered protocol will support the module. Verify the platform documentation before purchase.

Questions about this item

Will this 288-pin DDR5 RDIMM fit the DIMM slots on a SuperMicro X14SBM-TP4F?

Yes — the module is built to the standard 288-pin DDR5 RDIMM form factor used by the X14SBM-TP4F, so it seats directly in the board's memory slots without adapters.

What is the correct seating procedure for this registered ECC module, and what step do installers often miss?

Align the notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the 6400 MT/s speed and ECC function are active — the step most often skipped is confirming the registered buffer is recognised.

When should this 32 GB 2Rx4 kit be replaced in a 24/7 server workload?

Plan replacement if ECC correctable-error counts climb steadily over weeks, if the module fails memory diagnostics, or after the platform's qualified-vendor list is updated for a newer revision.
