Samsung 48GB 5600MHz DDR5 PC5-44800 ECC Unbuffered CL46 288-Pin DIMM 1.1V Dual Rank x8 Memory Module - M324R6GA3BB0-CWM

The Samsung M324R6GA3BB0-CWM is a 48GB DDR5 ECC Unbuffered DIMM (UDIMM) operating at 5600MHz (PC5-44800) with CAS latency CL46 and 1.1V operating voltage. This unique 48GB capacity module — achieved through Samsung's advanced 24Gb die technology — delivers an exceptional balance of capacity and DDR5 bandwidth for ECC UDIMM-compatible workstations and entry-level server platforms. Error-Correcting Code (ECC) technology continuously detects and corrects single-bit memory errors in real time, ensuring data integrity in mission-critical environments.

Compatibility

• Compatible with DDR5 ECC UDIMM slots only — not compatible with DDR5 RDIMM, Non-ECC UDIMM, or DDR4 slots
• CWM is the qualification code for this Samsung 48GB DDR5 5600MHz ECC UDIMM BB0 series — verify against your platform's memory QVL before ordering
• Verify your platform explicitly supports 48GB DDR5 ECC UDIMMs — not all DDR5 platforms support non-standard capacities
• Do not mix ECC UDIMMs with RDIMMs or Non-ECC UDIMMs in the same system

Frequently Asked Questions

Why is this module 48GB instead of a standard 32GB or 64GB?

The 48GB capacity is enabled by Samsung's 24Gb DRAM die technology, which allows a higher-density die to be used in a standard DIMM configuration. This creates a unique capacity point between 32GB and 64GB, offering flexible memory configurations for platforms that support it.

What does the CWM qualification code indicate?

CWM is Samsung's qualification code for this 48GB DDR5 5600MHz ECC UDIMM BB0 series — always verify against your platform's QVL before purchase.

Is this module compatible with DDR4 platforms?

No — DDR5 and DDR4 are not interchangeable. Always verify your platform's memory type requirement before ordering.

Whether you are building a high-capacity DDR5 ECC workstation, deploying an entry-level DDR5 server, or expanding a ZFS-based NAS with flexible capacity, the Samsung M324R6GA3BB0-CWM delivers the 48GB DDR5 ECC UDIMM reliability, error protection, and Samsung manufacturing quality your platform demands.
