Micron RDIMM 64GB DDR5 2Rx4 5600MHz PC5-44800 ECC REGISTERED MTC40F2046S1RC56BD1T

When every millisecond counts in virtualized environments or high-frequency trading platforms, the Micron MTC40F2046S1RC56BD1T steps away from consumer-grade memory with a server-first architecture. This 64GB DDR5 module pairs a 5600MT/s transfer rate with on-die ECC and registered buffering, delivering the signal integrity and error resilience that dense multi-slot servers demand. Unlike unbuffered DIMMs that falter under heavy load, the 2Rx4 dual-rank design keeps data flowing smoothly across 288 pins at just 1.1V.

Highlights

• 64GB capacity – enough for large in-memory databases, virtualization, and AI inference workloads.
• DDR5-5600 (PC5-44800) – up to 44.8GB/s bandwidth per module, ideal for next-gen CPUs.
• ECC Registered (RDIMM) – corrects single-bit errors and detects multi-bit faults, reducing downtime.
• Dual Rank (2Rx4) – improves interleaving and memory access parallelism in multi-channel systems.
• Low 1.1V operation – cuts power consumption and heat versus DDR4, extending server lifespan.
• 288-pin DIMM form factor – compatible with standard DDR5 server boards from major OEMs.

In daily use

Populate a 2-socket server with eight of these modules and you get 512GB of resilient memory that shrugs off transient bit flips caused by cosmic rays or electrical noise. Registered buffering isolates the memory controller from electrical loading, allowing stable operation even when every slot is filled. The CL46 latency is tuned for balanced throughput and responsiveness, making this module equally at home in a database server or a high-performance compute node. Because it runs at 1.1V, thermal output stays manageable in 1U chassis where airflow is limited.
