Samsung - M393A8K40B21-CTC - DDR4 - Módulo - 64 GB - DIMM 288-PIN - 2400 MHz / PC4-19200 CL19 1,2 V registado ECC

Server memory bottlenecks can cripple virtualization, database, and HPC workloads. The Samsung M393A8K40B21-CTC is a 64GB DDR4 registered ECC module engineered to eliminate data corruption and downtime in mission-critical environments. With a 2400 MHz clock speed and CL19 latency, it delivers the bandwidth and reliability your server infrastructure demands.

Who is it for

This module is built for IT administrators, data center operators, and system builders deploying servers and workstations that require high-capacity, error-correcting memory. It is ideal for virtualization hosts, in-memory databases, and compute-intensive applications where stability is non-negotiable.

Main features

• 64GB capacity – massive headroom for demanding workloads
• DDR4 SDRAM technology – improved speed and power efficiency over DDR3
• Registered ECC – detects and corrects single-bit errors, prevents multi-bit corruption
• 288-pin DIMM form factor – standard for DDR4 servers
• 2400 MHz data rate (PC4-19200) – balanced performance for modern platforms
• Low 1.2V operating voltage – reduces power consumption and heat
• CL19 CAS latency – optimized for server-class stability
