SAMSUNG M391A1K43DB2-CWEQ 8GB DDR4-3200 UDIMM ECC Server Memory

SKU CH-F25R-1W4QQ

Adds 8 GB of DDR4 ECC memory at 3200 MT/s to compatible servers and workstations

  • ECC support protects data integrity in servers
  • DDR4 3200 speed delivers responsive performance
  • 288-pin UDIMM fits standard server slots
  • Single 8 GB module simplifies capacity planning
  • Unbuffered design reduces latency for critical workloads

8GB DDR4-3200 ECC UDIMM

This Samsung module provides 8GB of DDR4 memory at 3200 MT/s with error-correcting code. It fits servers and workstations that require data integrity for continuous workloads. The unbuffered design suits platforms that do not support registered DIMMs.

Upgrade from non-ECC or lower-speed DDR4

Replacing standard UDIMMs with this ECC version adds single-bit error correction for improved reliability. The jump is worth it when the motherboard and CPU support ECC and the workload cannot tolerate silent data corruption. Systems without ECC support will not benefit from the extra parity bits.

Straightforward DIMM installation

Align the 288-pin module with the slot notch and press until the latches click. Common issues include mixing ECC and non-ECC modules or populating slots in the wrong order for the platform. Verify the system firmware recognises the full capacity and ECC function after boot.

Questions about this item

Will the 288-pin DIMM fit my motherboard's DDR4 slots?

The module uses the standard 288-pin DDR4 DIMM form factor, so it fits any desktop or server board with DDR4 UDIMM slots.

Do I need to change any BIOS settings when installing this ECC UDIMM?

Enable ECC in the BIOS after seating the module; the common mistake is leaving ECC disabled, so the system runs without error correction.

How do I know when this memory should be replaced?

Replace the module if memory diagnostics report uncorrectable ECC errors or the system logs repeated corrected errors over time.
