MICRON MTC40F2046S1RC56BD1 64GB DDR5 5600 RDIMM
The Micron MTC40F2046S1RC56BD1 is a 64GB DDR5 ECC Registered DIMM (RDIMM) running at 5600 MT/s, aimed at buyers provisioning enterprise servers, data centers, cloud platforms, and virtualization hosts. As a JEDEC-standard RDIMM, it suits high-density memory populations where registered signalling and error correction are required. Note that DDR5 modules cannot be mixed with DDR4 in the same platform — verify your CPU and motherboard support DDR5 RDIMMs before ordering.

Good to know
- DDR5 RDIMMs are not interchangeable with DDR4 modules or UDIMMs — confirm your platform’s memory Qualified Vendor List (QVL) and whether it supports 5600 MT/s, as many servers will train the module down to a lower supported speed.
- Within Micron’s DDR5 RDIMM lineup, this dual-rank (2Rx4) 64GB module balances capacity and channel population flexibility; dual-rank modules typically perform well in virtualization and cache-tier workloads, though check your CPU’s rank-per-channel limits for fully populated configurations.
- For homogeneous performance and easier RMA handling, buy modules of the same model, capacity, and rank in matched sets — mixing ranks or vendors within a channel can affect memory training and stability.
