When your server stalls as soon as you spin up a new virtual machine, the bottleneck is often memory. Kingston Technology 64GB 5600MT/s DDR5 ECC RDIMM RAM for PC/Server delivers a single-stick 64 GB of high-speed, error-correcting memory that keeps critical workloads running smoothly, freeing up slots and reducing power use.

Usages of a 64 GB RDIMM RAM

A single 64 GB module fits neatly into most rack servers and workstations.

  • Running multiple virtual machines on a single host.
  • Hosting large in-memory databases that require fast access.
  • Supporting AI inference workloads that need high bandwidth.
  • Power-efficient scaling of storage-heavy applications.
  • Consolidating workloads to reduce the number of physical servers.

Why Choose Kingston RDIMM RAM

If you manage a data centre, a high-performance workstation, or a cloud-hosted service, you know that downtime costs money and reputation. Traditional memory can struggle with large configurations, leading to crashes or slow response times. Kingston’s RDIMM design with built-in ECC gives you the reliability and speed needed to run demanding applications without fearing data loss or instability.

Key Features of a 64 GB RDIMM RAM
  • Capacity: 64 GB per module. Provides ample space for large workloads in a single DIMM.
  • Memory type: DDR5. Offers next-generation performance and efficiency.
  • Speed: 5600 MT/s. Delivers rapid data transfer for intensive tasks.
  • CAS Latency: CL46. Balances speed with stability for server environments.
  • Voltage: 1.1 V. Low power draw helps reduce overall energy costs.
  • Architecture: Registered (RDIMM). Improves signal integrity in multi-module setups.
  • ECC: Yes. Detects and corrects errors automatically, protecting data integrity.
  • Dual-rank (2R): Improves bandwidth utilisation for smoother operation.
  • Form factor: 288-pin DIMM. Fits standard server slots without modification.
  • Lead plating: Gold. Enhances connection reliability over time.

Benefits of Kingston RDIMM RAM

You gain confidence that critical services stay online, because ECC continuously safeguards data. The high 5600 MT/s speed reduces processing delays, letting you finish tasks faster and serve more users. With a single 64 GB stick you free up slots for future upgrades, saving space and simplifying future expansion. Lower voltage operation cuts electricity bills, and the registered design ensures stable performance even in large memory configurations, meaning less troubleshooting and lower total cost of ownership.
