32GB DDR5-6400 ECC RDIMM

This 32GB DDR5-6400 registered DIMM delivers 6400 MT/s bandwidth with ECC error correction for servers and workstations. The 2Rx8 organisation and 1.10V operation suit multi-channel platforms that require registered memory. It is built with Samsung DRAM ICs for consistent reliability.

Direct replacement for Samsung M321R4GA3PB2-CCP

This module replaces the listed Samsung part numbers in compatible systems. The upgrade is worthwhile when your platform supports DDR5-6400 registered ECC memory and you need additional capacity or are replacing a failed stick. It will not work in systems that only accept unbuffered or non-ECC modules.

Check motherboard qualified-vendor list

Verify that your server or workstation motherboard lists DDR5-6400 RDIMM support and the correct population order for 2Rx8 modules. Confirm the system BIOS is updated to the version that enables 6400 MT/s operation. Ensure you have a free 288-pin DDR5 DIMM slot and that the platform accepts registered ECC memory.

Questions about this item

Will the 288-pin DDR5 RDIMM fit in my server's DIMM slots?

This module uses the standard 288-pin DDR5 RDIMM form factor and operates at 1.10V, matching the physical and electrical requirements of DDR5 RDIMM server slots.

What is the correct way to seat this registered ECC module, and what step is often missed?

Align the module notch with the slot key, press firmly until both retention clips click, and verify the system recognises the full 32GB capacity and ECC function in BIOS.

When should I expect to replace this 2Rx8 Samsung-chipset module?

DDR5 server memory has no scheduled replacement interval; swap the module only if diagnostics report uncorrectable ECC errors or the system fails memory tests.
