Samsung M393A4K40BB1-CRC 32GB DDR4-2400 ECC RDIMM Server Memory

Overview

M393A4K40BB1-CRC is a Samsung 32GB DDR4 ECC Registered DIMM (RDIMM) rated at 2400 MT/s. It is designed for compatible server and workstation platforms that explicitly support DDR4 registered memory.

Product Positioning

This module is relevant for DDR4 server platforms that need higher per-slot capacity while remaining within the 2400 MT/s generation. In server environments, RDIMM selection should be based on the exact DIMM type, capacity, data rate, rank organization where specified, and the server vendor's memory population rules—not capacity alone.

Basic Technical Information

Typical Application Areas

• Enterprise and data-center servers
• Virtualization and private-cloud hosts
• Database, storage and networking systems
• Professional workstations supporting ECC RDIMM
• Server repair, expansion and qualified spare-parts sourcing

Selection Notes

DDR4 RDIMM is not interchangeable with DDR4 UDIMM or LRDIMM simply because the modules use the same DDR generation. Before ordering M393A4K40BB1-CRC, verify that the target platform supports DDR4 registered ECC memory and check the system vendor's supported capacity, speed, rank and DIMM population rules.

Replacement and Sourcing Considerations

If the exact module is unavailable, compare DDR generation, RDIMM architecture, capacity, data rate and platform qualification before considering an alternative. For installed enterprise systems, exact manufacturer part-number matching is the safest starting point.
