M391A1K43BB2-CTD

High-Performance DDR4 ECC UDIMM Server Memory Module for stable edge platforms with the M391A1K43BB2-CTD

The M391A1K43BB2-CTD is a Samsung DDR4 ECC UDIMM designed for enterprise systems that require unbuffered DIMM topology and deterministic JEDEC operation. In platforms built around Intel Xeon E and select entry Xeon Scalable or AMD EPYC embedded-class designs that expose ECC-enabled UDIMM slots, the M391A1K43BB2-CTD delivers predictable memory behavior for OS, hypervisor, and appliance workloads where stability is prioritized over overclock profiles.

Operating at 2666MT/s on a 288-pin, 1.2V low-profile module, the M391A1K43BB2-CTD supports bandwidth requirements typical of PCIe-based I/O expansion and mixed storage architectures (SATA/NVMe) without introducing registered-memory dependencies. Its 72-bit ECC data path improves resilience under sustained packet processing, logging, and edge analytics, while the single-rank x8 organization helps maintain signal integrity and compatibility across compact motherboards with constrained trace routing.

Why Choose the M391A1K43BB2-CTD?

The M391A1K43BB2-CTD is a pragmatic capacity increment for ECC UDIMM systems where density-to-cost balance and operational consistency matter. It enables scalable, incremental upgrades in 8GB steps, supports mixed-density population strategies, and aligns with enterprise reliability expectations for always-on network, security, and embedded deployments.

Samsung engineers server memory for controlled manufacturing variability and long-term platform alignment, emphasizing JEDEC compliance, conservative operating margins, and validation practices that support modern data centre standards for uptime, serviceability, and lifecycle-managed configurations.

Key Applications:

Entry server memory expansion
Network and security appliances
Embedded and edge server platforms
ECC-enabled UDIMM server nodes

At Happyware - Server Hardware you benefit from non-binding offers tailored to your deployment and from an extended warranty up to 6 years, supporting predictable refresh cycles and risk-managed rollouts for M391A1K43BB2-CTD-based memory configurations.
