32GB DDR4 3200 ECC RDIMM

This A-Tech module is a 32GB DDR4 3200 ECC Registered DIMM built as a compatible replacement for Samsung M393A4G40AB3-CWE and M393A4G40BB3-CWE. It runs at 1.20V with CL22 latency and uses a 1Rx4 organisation on Samsung chipset. The 288-pin form factor fits standard server and workstation memory slots.

Suits ECC registered platforms only

The module requires a motherboard and CPU that support ECC Registered DDR4 memory; it will not function in consumer desktops or laptops that accept only unbuffered non-ECC DIMMs. Builders who need unbuffered memory or a different capacity should look at other parts.

Registered ECC with 1Rx4 organisation

The single specification that decides fit is the Registered ECC design with 1Rx4 rank structure; the system must explicitly support registered ECC modules in this configuration for the memory to initialise and operate correctly.

Questions about this item

Will this 32GB DDR4 3200 ECC RDIMM run alongside my existing 1Rx4 modules at CL22?

Yes, this module uses 1Rx4 organisation and CL22 timing at 1.20V, matching the electrical and timing profile of other 1Rx4 DDR4 3200 RDIMMs so they can operate together when the platform supports mixed capacities.

How can I confirm the module is registered and ECC after installation?

The BIOS or system management utility will report the DIMM as a Registered ECC module running at DDR4 3200 with a CAS latency of 22 and 1.20V operation.

Does the box include only the 288-pin DIMM or are extra parts supplied?

The package contains the single 32GB DDR4 3200 ECC RDIMM; no additional cables, brackets or cooling accessories are included.
