SAMSUNG M391A4G43AB1-CWE 32GB DDR4 3200MHz CL22 ECC server RAM

SKU CH-WHFA-Z3MRY MPN M391A4G43AB1-CWE

32 GB DDR4 server memory module with ECC running at 3200 MHz CL22 on 1.20 V

  • 32 GB capacity supports large server workloads
  • DDR4 3200 MHz speed delivers high data throughput
  • CL22 latency ensures responsive memory access
  • ECC protection detects and corrects data errors
  • 20 V operation reduces power consumption

32GB DDR4 ECC DIMM for servers

This 32GB DDR4 module operates at 3200MHz with CL22 latency and ECC error correction. It uses a 288-pin unbuffered DIMM form factor at 1.20V. The refurbished unit is suited for server workloads that require data integrity.

Capacity headroom at 32GB per module

A single 32GB stick provides substantial memory for virtualisation, databases and multi-user applications. Systems with limited DIMM slots benefit from the high density. Workloads exceeding the installed capacity will swap to storage and lose performance.

ECC unbuffered DDR4-3200 specification

The module follows the DDR4-3200/PC4-25600 standard with on-die ECC and no register buffer. Motherboards must support unbuffered ECC DIMMs at this speed and voltage. Platforms requiring registered or load-reduced memory cannot use this part.

  • 32 GB capacity supports large server workloads
  • DDR4 3200 MHz speed delivers high data throughput
  • CL22 latency ensures responsive memory access

Questions about this item

Will this 32 GB DDR4-3200 CL22 ECC module run alongside my existing DDR4 modules?

It is an unbuffered 288-pin DIMM at 1.20 V with CL22 timing. The motherboard will set a common speed and latency for all installed sticks.

How can I confirm the module is detected at 3200 MHz with ECC active after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should show 32 GB at 3200 MHz with ECC enabled.

What is included with the M391A4G43AB1-CWE module and what must be sourced separately?

The box contains the single 32 GB DDR4 DIMM. Any additional DIMMs, CPU cooler clearance parts or motherboard firmware updates are not included.
