Server-ready DDR5 ECC RDIMM

This 32GB A-Tech module delivers DDR5 5600 performance with error-correcting code and registered signalling for stable server and workstation operation. It runs at the standard 1.10V and uses Samsung DRAM chips in a 2Rx8 layout. The 288-pin form factor fits compatible DDR5 RDIMM slots.

Suited for ECC registered platforms

Administrators expanding or repairing Samsung M321R4GA3EB0-CWM or M321R4GA3PB0-CWM configurations will find a direct replacement here. Builders needing unbuffered memory, non-ECC modules or a different rank structure should select another part.

Registered ECC with 2Rx8 organisation

The single specification that decides fit is the combination of registered ECC and 2Rx8 rank on a 288-pin DDR5 5600 module. Only systems that explicitly support this exact configuration can use the memory.

Questions about this item

Does my server need DDR5 RDIMM slots to use this 32GB 5600MHz module?

Yes, the module is a 288-pin DDR5 RDIMM that requires a server or workstation motherboard with DDR5 RDIMM slots.

Can I mix this 2Rx8 ECC RDIMM with existing 1Rx8 modules in the same system?

Mixing ranks is often supported, but the system manual should be checked for approved rank combinations and channel population rules.

How do I confirm the module runs at 5600MHz with CL40 after installation?

Check the BIOS or UEFI memory information screen; it should report DDR5-5600 speed, CAS latency 40, and 1.10V operation.
