32GB DDR4 ECC UDIMM Server Memory

This 32GB DDR4 3200MHz ECC unbuffered DIMM is built for servers and workstations that require error-correcting memory. It operates at 1.2V with CL22 latency and uses a 2Rx8 rank configuration. The module is a compatible replacement for Hynix HMAA4GU7AJR8N-XN and HMAA4GU7CJR8N-XN parts.

Suits ECC UDIMM platforms only

This module fits systems that accept DDR4 ECC unbuffered UDIMMs running at 3200MHz with 2Rx8 organisation. It will not work in platforms that require registered or load-reduced DIMMs, nor in consumer boards that lack ECC support in the BIOS. Buyers needing non-ECC memory or higher capacities per slot should look elsewhere.

DDR4 3200MHz ECC UDIMM 2Rx8 specification

The decisive specification is the DDR4 3200MHz ECC unbuffered UDIMM 2Rx8 design at 1.2V with CL22 timing. Verify that your motherboard and CPU support this exact combination of speed, ECC type, rank and voltage before ordering. A mismatch in any of these parameters will prevent the module from functioning.

Questions about this item

Does my server motherboard need a 288-pin DDR4 slot to accept this 32GB ECC UDIMM?

Yes, this module is a 288-pin DDR4 DIMM that requires a standard DDR4 UDIMM slot on the motherboard.

Will this CL22 3200MHz module run reliably alongside slower DDR4 sticks I already have installed?

The system will operate all modules at the speed and timings of the slowest installed stick, so this CL22 module will downclock to match older DDR4 memory.

How can I confirm the 32GB module is detected at 3200MHz with ECC active after installation?

Check the BIOS memory information screen or run a tool such as dmidecode or CPU-Z to verify capacity, speed, and ECC status.
