M393A1K43BB1-CTD Samsung 1x8GB DDR4 RDIMM ECC RAM

High-Density DDR4 ECC Registered RDIMM for Enterprise Servers with the M393A1K43BB1-CTD

The M393A1K43BB1-CTD is a Samsung DDR4 ECC Registered DIMM engineered for predictable memory expansion in DDR4 RDIMM server platforms where signal integrity and uptime are mandatory. As a 288-pin, 8GB module operating at 2666MT/s JEDEC, it supports balanced bandwidth and stable timing behavior for mixed production workloads.

Designed around registered buffering and ECC protection, the M393A1K43BB1-CTD helps maintain platform reliability under high concurrency typical of virtualized CPU estates, database nodes, and general-purpose compute. Its single-rank x8 organization and 72-bit data path align with mainstream Intel Xeon and AMD EPYC generations that expose multi-channel DDR4 memory controllers, while the 1.2V operating point supports efficient power and thermal envelopes in dense 1U/2U designs. When paired with PCIe-centric expansion and NVMe/SAS storage tiers, this module contributes to consistent latency behavior by avoiding memory-induced error events and reducing unplanned maintenance windows.

Why Choose the M393A1K43BB1-CTD?

The M393A1K43BB1-CTD is a practical choice for enterprises standardizing on DDR4 RDIMM footprints, enabling scalable capacity planning without changing server topology. It delivers a strong density-to-compatibility ratio for populated memory channels, supports fleet-wide serviceability, and helps preserve deterministic performance under sustained load through ECC and registered design characteristics.

Samsung applies a validation-led engineering approach focused on lifecycle stability, controlled component sourcing, and compliance with modern data centre reliability expectations, making this memory module suitable for long-running deployments and structured change management.

Key Applications:

• Server memory expansion and maintenance for DDR4 RDIMM systems
• Virtualization and VDI host memory population
• Database and middleware nodes requiring ECC protection
• General-purpose enterprise compute in 1U/2U servers
