8GB DDR4 3200 ECC UDIMM Server Module

This 8GB DDR4 3200 ECC UDIMM module targets server and workstation administrators who need single-stick capacity expansion with error-correcting memory. It operates at 1.20V standard DDR4 voltage and uses a 288-pin unbuffered DIMM form factor for direct installation.

8GB capacity and 3200 speed headroom

The 8GB capacity handles everyday virtualisation hosts, database buffers and multi-user workloads without paging pressure. At DDR4 3200 (PC4-25600) with CL22 latency the module saturates typical dual-channel server controllers, while heavier analytical jobs or large in-memory datasets will exceed the single-module limit.

Replaces Samsung M391A1K43DB2-CWE equivalent

This module serves as a direct replacement for the Samsung M391A1K43DB2-CWE part, matching 1Rx8 organisation and ECC UDIMM specification. The upgrade is justified when ECC integrity is required and the platform supports unbuffered DDR4 3200 speeds.

Questions about this item

Will this DDR4 3200 ECC UDIMM operate correctly when installed alongside existing DDR4 ECC UDIMM modules in the same server?

Mixing modules with different speeds or timings typically forces all memory to run at the lowest common speed and loosest latency. Verify that your platform supports mixed populations and populate identical modules per channel for best stability.

How can I confirm the 1Rx8 ECC UDIMM is recognised at 3200 MHz with CL22 latency after installation?

Enter the system BIOS or UEFI and open the memory information screen; it should report 3200 MT/s, CL22 timings, 1.20 V operation and ECC enabled for the new module.

Does the single 288-pin DDR4 3200 ECC UDIMM ship alone, or are additional components such as heatsinks or cables included?

The box contains one 8 GB 1Rx8 DDR4 3200 ECC UDIMM module only; no heatsinks, cables or mounting hardware are supplied.
