Micron MTC40F1046S1RC48BA1 — 40GB DDR5 Server Memory Module

Description

The Micron MTC40F1046S1RC48BA1 is a high-capacity 40GB DDR5 server memory module designed to increase the available system memory of compatible enterprise computing platforms.

Utilizing DDR5 SDRAM technology, this Micron module is intended for modern server environments where higher memory capacity is required to support virtual machines, databases, enterprise applications, large datasets, analytics, and concurrent workloads.

Its 40GB capacity provides substantial additional memory headroom, making it suitable for systems that require greater RAM density while maintaining an enterprise-oriented memory architecture. It can be deployed as part of a multi-DIMM configuration when supported by the host platform and its memory population rules.

The “RC” designation in the supplied part number indicates that the module should be treated as a specific server-memory configuration rather than a generic desktop DIMM. For deployment, the exact ECC, registered/buffered configuration, speed grade, rank organization, and electrical characteristics should be verified against the module SPD and the server manufacturer’s qualified memory list.

Applications

The MTC40F1046S1RC48BA1 is suitable for compatible systems used in:

Enterprise server infrastructure
Data-center environments
Virtualization and server consolidation
Cloud computing
Database servers
Enterprise application hosting
Data analytics and processing
High-memory computing
Business-critical applications
Professional computing infrastructure
Large-scale workload consolidation

Compatibility

The module should be installed only in servers or professional systems that explicitly support its complete DDR5 memory configuration.

Before installation, verify:

Server manufacturer and model
DDR5 memory support
Supported server DIMM type
ECC requirements
Registered/buffered memory requirements
Supported module capacity
Memory speed
Rank and memory organization
Processor memory-controller compatibility
Maximum supported system memory
DIMM channel and population rules

Important: DDR5 memory is not backward-compatible with DDR4 DIMM slots. Mixing unsupported memory types, capacities, or configurations can result in reduced performance or failure to POST.
