A-Tech 16GB DDR4 3200 ECC RDIMM

This 16GB registered DIMM targets server and workstation platforms that require ECC protection and registered signalling. It runs at DDR4 3200 (PC4-25600) with CL22 latency and 1.20V operation. The module uses a 1Rx4 organisation on Micron chipset.

288-pin DIMM installation and compatibility

Installation follows the standard 288-pin DDR4 DIMM procedure; seat the module until the retention clips engage. The registered design adds electrical load, so the memory controller must support registered DIMMs. Verify the platform qualified vendor list before purchase because unregistered systems will not accept this module.

16GB capacity headroom for ECC workloads

A single 16GB rank handles typical virtualisation, database and compute tasks that benefit from error correction. Workloads needing larger per-socket memory footprints will require additional populated slots up to the platform limit. Systems that do not support ECC or registered memory cannot use this module.

Questions about this item

How can I confirm the 16GB DDR4 3200 ECC RDIMM is running at CL22 and 1.20V after installation?

Enter the system BIOS or UEFI and open the memory information screen; it will show the detected speed as 3200 MT/s, the CAS latency as CL22, and the operating voltage as 1.20V, confirming the module is configured correctly.

What comes in the package and do I need any extra parts to install this 288-pin RDIMM?

The box contains a single 16GB 288-pin DDR4 ECC RDIMM; no additional cables, brackets, or cooling parts are required — just an available registered DIMM slot on a compatible server or workstation motherboard.

Which Micron part numbers does this A-Tech module replace so I can pick the right one?

This module is a compatible replacement for Micron MTA18ASF2G72PZ-3G2E2 and MTA18ASF2G72PZ-3G2R1; match either of those part numbers from your system’s memory list to ensure you select the correct version.
