32GB DDR4 3200 ECC RDIMM Server Memory

This 32GB A-Tech module is a compatible replacement for Samsung M393A4K40BB2-CWE and M393A4K0DB3-CWE. It runs at DDR4 3200 with CL22 latency and 1.20V operation. The registered DIMM includes ECC for error correction in server and workstation environments.

Suited for systems requiring registered ECC memory

Buyers needing non-ECC unbuffered memory for consumer desktops or laptops should look at something else. This module is built for platforms that support registered DIMMs and ECC functionality. Verify your motherboard or server documentation before purchase.

Registered ECC with 2Rx4 organisation

The 2Rx4 rank configuration and registered buffer define compatibility with specific server chipsets and memory controllers. Match these parameters exactly to the system's qualified vendor list to ensure stable operation.

Preguntas sobre este artículo

How much power does the 1.20 V DDR4 3200 ECC RDIMM draw when the server runs continuously?

The module operates at the standard DDR4 voltage of 1.20 V, which keeps power draw low during sustained workloads.

What must the motherboard provide for this 288-pin registered DIMM to function?

The board needs a DDR4 RDIMM slot that supports ECC, registered operation, and 2Rx4 organisation at 3200 MT/s.

Can this CL22 3200 module share a channel with slower DDR4 DIMMs already in the system?

Yes — the memory controller will run all modules at the lowest common speed and latency, so mixing is possible.
