Registered ECC DDR5-6400 servergeheugen MICRON Crucial 64 GB (MTC40F2046S1RC64BH1T)

Registered ECC DDR5-6400 server memory from MICRON Crucial, 64 GB capacity, is designed for systems that require error correction and registered buffering to maintain stability under sustained loads. This module implements ECC to detect and correct single-bit memory errors and uses a register to offload electrical load from the memory controller, helping support larger memory configurations and improving reliability in multi-socket servers and workstation platforms.

Advantages

This 64 GB registered ECC DDR5-6400 module provides high memory bandwidth and low-latency timings characteristic of DDR5-6400 class components while offering error-correction capabilities for improved data integrity. The registered buffer reduces signal stress on the motherboard and memory controller, enabling denser memory populations. The module is engineered to meet server-grade operating conditions for continuous operation and sustained throughput required by enterprise workloads.

Suitable for

• Enterprise servers and multi-socket systems requiring ECC and registered memory support
• Virtualization hosts running multiple VMs with high memory demands
• Database servers and in-memory processing where data integrity is important
• Workstations used for scientific computing, simulation, and content creation with large dataset handling

When it may not be suitable

This registered ECC module is not compatible with consumer-grade desktop motherboards that only support unbuffered (UDIMM) non-ECC memory. Systems that do not support DDR5-6400 speeds or registered ECC functionality will either not boot or will run the module at a lower supported speed without ECC/registration benefits. Check system compatibility before purchase.

Key specifications

• Memory type: DDR5
• Capacity: 64 GB
• Form factor: Server DIMM (RDIMM)
• Speed grade: DDR5-6400
• Error correction: Registered ECC (error-correcting code with register)
• Intended use: Server and workstation platforms

How to use

Install the module in a compatible server or workstation memory slot following the motherboard vendor's installation instructions and antistatic precautions. Populate memory channels according to the system's supported configurations to maintain channel symmetry and optimal performance. After physical installation, verify BIOS/UEFI settings to ensure the module is recognized, ECC is enabled if available, and the memory runs at the desired speed. Monitor system logs and hardware diagnostics on initial boot to confirm stable operation.

What to consider before purchase

• Motherboard support for DDR5, registered memory (RDIMM), and ECC functionality
• Processor and platform support for DDR5-6400 speed grades and multi-rank modules
• Maximum supported memory per channel and total system capacity
• Thermal conditions inside the server chassis and airflow for continuous operation

Recommendations

For reliable operation, install memory modules in matched pairs or kits as recommended by the server vendor, verify BIOS firmware is up to date, and enable ECC features in system firmware. If populating multiple slots, follow the motherboard's channel population guidelines to preserve performance and stability.
