Micron 64GB DDR5 RDIMM 2Rx4 6400 MT/s CL52 ECC Registered Μνήμη Server (16Gbit, Tray)

For server and workstation builds that demand both capacity and speed, this Micron 64GB DDR5 registered DIMM stands apart from standard modules by pairing high-density 16Gbit DRAM with a 2Rx4 rank configuration to maintain signal integrity under load. Running at 6400 MT/s, it delivers the bandwidth needed for virtualization, in-memory databases, and heavy multi-threaded workloads, while ECC and registered buffering protect data and stabilize the memory bus in multi-DIMM configurations.

Highlights

• 64GB capacity on a single module, ideal for dense server memory configurations.
• DDR5-6400 (PC5-51200) with CL52 latency for balanced performance and efficiency.
• Registered DIMM (RDIMM) with on-module buffering to reduce electrical load and improve reliability.
• ECC error correction for mission-critical data integrity.
• 2Rx4 dual-rank x4 organization using 16Gbit DRAM chips for optimal capacity and performance.
• 288-pin standard DDR5 DIMM form factor, compatible with DDR5 server boards.
• Low 1.1V operating voltage for improved energy efficiency over DDR4.
• Supplied in tray packaging for system integrators and volume deployments.

In daily use

This module is engineered for continuous operation in servers and workstations where downtime is not an option. The registered design allows multiple modules to be populated per channel without sacrificing stability, and ECC detects and corrects single-bit errors on the fly. With 64GB per stick, a typical dual-socket server can reach 512GB or more with just eight modules, making it a practical choice for memory-hungry applications such as AI inference, large-scale analytics, and consolidated virtual machines. The 6400 MT/s speed ensures that modern processors are fed with data quickly, reducing bottlenecks in memory-intensive tasks.
