Micron MTC40F2046S1RC48BR

Overview

The Micron MTC40F2046S1RC48BR is a 64GB DDR5 registered DIMM (RDIMM) designed to enhance server and workstation memory capacity and performance. Running at 4800 MHz, it provides the bandwidth necessary for demanding workloads such as real-time analytics, AI inference, and virtualized environments. Its built-in Error Correction Code (ECC) ensures data integrity by detecting and correcting errors before they affect system stability, making it a reliable choice for critical applications.

Key features

• 64GB capacity expands memory headroom to support multitasking and virtualization with ease
• DDR5 technology operating at 4800 MHz delivers high data transfer rates for improved throughput
• Registered DIMM design buffers signals between the memory controller and DRAM, enhancing stability in multi-module server setups
• ECC support actively corrects data errors to maintain system reliability and prevent crashes
• CL40 latency offers a balanced combination of speed and consistent performance
• Low 1.1 V operating voltage reduces power consumption, benefiting energy-conscious data centers
• Standard 288-pin form factor ensures compatibility with motherboards that support DDR5 RDIMM memory

Connectivity and compatibility

This memory module fits any server or workstation motherboard that supports 288-pin DDR5 registered DIMMs. Its registered design helps maintain signal integrity when multiple modules are installed, making it suitable for multi-channel memory configurations common in enterprise environments. ECC functionality ensures compatibility with systems requiring high data reliability.

Performance and reliability

With a 4800 MHz data rate and CL40 latency, this module balances fast data access with consistent timing, which is crucial for workloads that demand both speed and stability. The ECC feature actively detects and corrects memory errors, reducing the risk of system crashes or data corruption. Its registered buffer further stabilizes signals, especially in densely populated memory slots, ensuring dependable operation under heavy server loads.

Ideal uses and environments

This 64GB DDR5 RDIMM is well suited to data centers, cloud service providers, and scientific computing environments where large memory capacity and error-free operation are essential. It supports virtualization, database management, and AI inference tasks that require both high bandwidth and system reliability. Its energy-efficient design also makes it a practical choice for organizations aiming to reduce power consumption without sacrificing performance.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
