MPN #: KSM64R52BD4-128MB

Running demanding workloads on an ageing server can cause slowdowns and crashes, leaving you frustrated and unproductive. Kingston (KSM64R52BD4-128MB) 128 GB DDR5, 6400 MHz ECC RDIMM RAM for PC/Server gives you a massive 128 GB of high-speed DDR5 memory with error-correcting capabilities, keeping your systems fast, stable and reliable for intensive tasks.

Usages of a 6400 MHz DDR5 RAM

Ideal for virtualisation, large-scale data analysis and high-performance computing, this module fits seamlessly into daily server operations, delivering instant responsiveness when you launch multiple VMs or process big data sets.

Benefits of Kingston DDR5 RAM
  • Maximum stability: On-die ECC continuously corrects errors, preventing data corruption.
  • Ultra-fast performance: 6400 MT/s data rate speeds up application loading and processing.
  • Low power draw: 1.1 V operation reduces energy costs and heat output.
  • Future-proof capacity: 128 GB lets you run more workloads without upgrading again soon.
  • Reliable build: Gold lead plating ensures long-term connector durability.

Kingston DDR5 RAM

Choosing this Kingston module means you get enterprise-grade reliability without the complexity of multiple sticks.
