MPN #: KSM64R52BD4-128MB

When your server stalls under heavy workloads, every millisecond counts, and you need memory that never compromises stability. Kingston (KSM64R52BD4-128MB) 128 GB DDR5, 6400 MHz ECC RDIMM RAM for PC/Server delivers massive 128 GB capacity with ultra-fast 6400 MHz data rates, ensuring smooth multitasking and error-free operation for demanding environments.

Usages of a 6400 MHz ECC RAM

Ideal for mission-critical tasks, this module fits seamlessly into daily workflows:

  • Running virtual machines on enterprise hypervisors
  • Processing large datasets in scientific research
  • Hosting high-traffic web and database servers
  • Supporting AI inference workloads that need reliable memory
  • Powering financial trading platforms where latency matters

Why Choose Kingston ECC RAM

If you manage a data centre or high-performance workstation, you know that memory errors can cause costly downtime and data loss. Traditional RAM often lacks the safeguards required for continuous operation, leaving you to troubleshoot unpredictable crashes. Kingston ECC RAM provides built-in error correction and the speed needed to keep your applications responsive, eliminating the guesswork and letting you focus on growth.

Key Features of a 6400 MHz ECC RAM
  • JEDEC standard: Yes. Guarantees compatibility with industry-approved specifications.
  • Lead plating: Gold. Offers superior corrosion resistance for long-term reliability.
  • Programming power voltage (VPP): 1.8 V. Ensures efficient programming of the memory chips.
  • SPD profile: Yes. Allows automatic configuration by the system BIOS.
  • Row active time: 32 ns. Provides quick access to stored data.
  • Refresh row cycle time: 295 ns. Maintains data integrity during continuous operation.
  • Row cycle time: 48 ns. Contributes to the overall high performance of the module.
  • Module configuration: 16384M x 80. Defines the internal organization for optimal speed.
  • Memory voltage: 1.1 V. Low power consumption while delivering DDR5 performance.
  • CAS latency: 52. Balances speed with stability for demanding workloads.

Benefits of Kingston ECC RAM

With Kingston ECC RAM you avoid costly system crashes caused by memory errors, saving you time and maintenance expenses. The high 6400 MHz frequency reduces processing delays, letting you complete tasks faster and improve overall productivity. Low-voltage operation cuts energy costs, while the gold-plated contacts extend the module’s lifespan, meaning fewer replacements and less downtime.
