32GB DDR4 3200MHz ECC RDIMM

This A-Tech module provides 32GB of registered ECC memory for servers and workstations that require DDR4 3200MHz (PC4-25600) RDIMMs. It uses Micron chipset components and a 2Rx4 rank configuration to deliver error-correcting reliability in compatible 288-pin slots. The module operates at the standard DDR4 voltage of 1.20V.

Thermals noise and power draw

Registered ECC DDR4 modules run at 1.20V, keeping power draw low during typical server workloads. The 2Rx4 organisation spreads access across ranks, helping maintain steady temperatures without active cooling on the DIMM itself. CL22 latency at 3200MHz supports responsive operation under normal multi-tasking conditions.

Sustained load behaviour

Under continuous heavy workloads the registered buffer reduces electrical loading on the memory controller, allowing stable throughput across all 32GB. ECC detection and correction operates continuously to prevent data corruption during extended compute tasks. The module is validated as a compatible replacement for Micron MTA36ASF4G72PZ-3G2E2, MTA36ASF4G72PZ-3G2E7, MTA36ASF4G72PZ-3G2J3 and MTA36ASF4G72PZ-3G2R1 part numbers.

Questions about this item

How do I install the 288-pin DDR4 RDIMM and which step is often missed?

Align the notch with the slot key, press firmly until both side clips click shut, then confirm the motherboard detects the full 32GB at 3200MHz in BIOS.

What maintenance or replacement will the 32GB ECC RDIMM need over its service life?

No scheduled maintenance is required; the module either passes POST and runs indefinitely or is replaced under lifetime warranty if errors appear.

What limit appears first when the 2Rx4 registered DIMM runs sustained workloads at 1.2V?

The CL22 latency at 3200MHz sets the throughput ceiling before thermal or voltage limits become a factor.
