Samsung - DDR5 - module - 128 GB - DIMM 288-PIN - 6400 MHz / PC5-44800 1,1 V registered ECC

Engineered for mission-critical server and workstation environments, the Samsung M321RAJA0MB2-CCP sets a new benchmark in memory performance. This 128GB DDR5 module operates at an impressive 6400 MHz, delivering a staggering 51.2 GB/s of bandwidth per channel—nearly double that of DDR4. With error-correcting code (ECC) and registered buffering, it ensures data integrity and system stability under heavy workloads, making it the ideal choice for virtualization, in-memory databases, and high-performance computing.

Highlights

• Massive 128GB capacity on a single DIMM for maximum density
• DDR5 technology with 6400 MHz speed (PC5-44800)
• ECC and registered design for enhanced reliability
• Low 1.1V operating voltage for improved energy efficiency
• Dual-rank architecture with 2Rx4 configuration
• 288-pin gold-plated connector for superior conductivity
• Standard profile fits most server and workstation chassis

In daily use

Deploying this module translates to fewer memory slots occupied, leaving room for future expansion. The on-die ECC and registered buffer reduce signal loading, allowing stable operation even when all channels are populated. Whether running complex simulations or managing large-scale virtualization, this memory delivers consistent performance without compromising data accuracy. Its energy-efficient design also helps lower total cost of ownership by reducing power consumption and cooling requirements.
