M393A4K40BB2-CTD Samsung 1x32GB DDR4 ECC RAM

High-Density DDR4 RDIMM Server Memory featuring Registered ECC reliability with the M393A4K40BB2-CTD

The M393A4K40BB2-CTD is a Samsung 32GB DDR4 Registered ECC DIMM engineered for enterprise CPU platforms that depend on RDIMM signal integrity and predictable memory timing under sustained load. By using a registered buffering architecture with ECC, the M393A4K40BB2-CTD supports stable scaling across multi-socket server boards where memory population and channel density are critical to throughput consistency.

Designed for DDR4 RDIMM generations supporting 2666MT/s operation, the M393A4K40BB2-CTD aligns with balanced CPU-to-memory bandwidth planning for virtualisation hosts, application servers, and general-purpose compute nodes. Its dual-rank organisation improves effective parallelism for typical mixed workloads, while the 288-pin 1.2V electrical profile supports efficient power and thermal envelopes in dense rack deployments. The low-profile form factor helps maintain airflow paths around adjacent DIMM banks and CPU heat sinks, reducing operational risk during capacity expansions and node refresh cycles.

Why Choose the M393A4K40BB2-CTD?

The M393A4K40BB2-CTD delivers a practical density-to-performance ratio for DDR4 RDIMM infrastructures by combining 32GB capacity with registered ECC safeguards that protect uptime and data integrity. For IT teams standardising memory across fleets, the M393A4K40BB2-CTD enables predictable scaling profiles, cleaner qualification processes, and consistent behaviour when expanding memory footprints to meet VM consolidation or database cache demands.

Samsung designs enterprise DRAM with a focus on controller compatibility, manufacturing consistency, and long-term stability for 24/7 data centre operations. This engineering approach supports modern platform requirements such as high DIMM population, tight signal margins, and dependable error management aligned with current server reliability standards.
