32GB DDR4 ECC RDIMM for Servers

This 32GB DDR4 3200 module is a registered ECC DIMM built for server and workstation platforms. It replaces the Hynix HMAA4GR7CJR4N-XN part and operates at the standard DDR4 voltage of 1.20V. The module uses a 1Rx4 rank organisation with a CAS latency of CL22. Buyers who need non-ECC unbuffered memory for consumer desktop boards cannot use this module.

Capacity and headroom for virtualisation

The single 32GB stick adds substantial memory capacity for multi-VM hosts, database caches or large dataset workloads. At DDR4 3200 (PC4-25600) it delivers the rated bandwidth for current server chipsets that support this speed. Systems that require higher density per slot or faster data rates will need modules with different specifications.

Thermals noise and power in normal use

Running at the standard 1.20V DDR4 voltage keeps power draw low inside densely populated chassis. The registered buffer reduces electrical load on the memory controller, aiding signal integrity without adding active cooling requirements. In typical server airflow the module operates silently and stays within thermal limits without supplemental fan speed increases.

Questions about this item

Will this DDR4 3200 module run alongside older DDR4 sticks at a common speed?

DDR4 modules with different rated speeds will all operate at the lowest common frequency supported by the platform; verify your system's maximum memory speed and populate slots per the motherboard manual for stable operation.

How can I confirm the ECC RDIMM is recognised and error-correction is active after installation?

Enter the system BIOS or UEFI and check that the installed capacity shows 32 GB, the speed reads 3200 MT/s, and ECC status is reported as enabled or active.

Does the single 288-pin DIMM ship alone, or are extra parts such as a heatspreader or installation tool included?

The box contains one 32 GB 288-pin DDR4 ECC RDIMM module only; no additional hardware, heatspreader, or tools are supplied.
