Micron MTC40F2046S1RC64BD2R DDR5 RDIMM 64GB 2Rx4 6400 CL52 server RAM

SKU CH-ENF3-ZAXGE MPN MTC40F2046S1RC64BD2R

Registered DDR5 server module delivering 64 GB at 6400 MHz with CL52 latency and 2Rx4 organisation

  • 64 GB capacity supports large virtualised workloads
  • DDR5 6400 MHz speed delivers high data throughput
  • CL52 latency enables responsive server performance
  • 2Rx4 organisation improves memory channel efficiency
  • RDIMM form factor ensures registered signal integrity

64 GB DDR5 RDIMM server module

Micron MTC40F2046S1RC64BD2R is a 64 GB DDR5 RDIMM built for servers and workstations that require registered memory. It runs at 6400 MHz with a CL52 latency and a 2Rx4 organisation based on 16 Gbit DRAM. The single-module pack suits upgrades or new deployments where capacity per slot matters.

Suited for registered DDR5 platforms only

This module fits systems that accept DDR5 RDIMMs with 2Rx4 density and 6400 MHz operation. It will not work in boards limited to UDIMM, lower speeds or smaller maximum capacity per slot. Buyers needing ECC UDIMMs, slower registered speeds or higher densities per DIMM should look elsewhere.

6400 MHz speed with CL52 timing

The decisive specification is the 6400 MHz data rate combined with CL52 latency. The platform memory controller must support this exact speed and timing for stable operation. Verify the qualified vendor list before purchase.

商品問答

What server motherboard and CPU combination is required to run this MTC40F2046S1RC64BD2R module at 6400 MHz?

A platform with a DDR5 RDIMM slot and a memory controller rated for 6400 MT/s is needed; the motherboard must also support registered ECC DIMMs and the 2Rx4 organisation of this 64 GB stick.

How does this 2Rx4 RDIMM behave when installed alongside modules of a different rank or speed?

The memory controller will train all populated slots to a common frequency and timing; mixing ranks or speeds typically forces the slowest common denominator, so identical modules are recommended for stable 6400 MHz operation.

How can I confirm this module is operating at 6400 MHz CL52 after installation?

Enter the system BIOS or use a hardware information utility such as dmidecode or CPU-Z; both will report the current data rate as 6400 MT/s and the CAS latency as 52 cycles for this DIMM.
