The Samsung M321R4GA0PB0-CWM is a 32GB DDR5 memory module designed for compatible server platforms requiring ECC registered memory. Operating at a rated data transfer speed of 5600 MT/s, it combines DDR5 technology with a single-rank 1Rx4 organization for supported enterprise computing configurations.
This 288-pin Registered DIMM (RDIMM) uses the PC5-44800 memory standard, features CL46 latency, and operates at a nominal voltage of 1.1V. It is intended for compatible servers and should not be treated as a substitute for standard desktop UDIMM memory.
Key Features
- 32GB Memory Capacity: Provides 32GB of DDR5 SDRAM in one memory module.
- DDR5-5600 Data Rate: Supports a rated transfer speed of 5600 MT/s and the PC5-44800 classification.
- ECC Registered Memory: Combines error-correcting code support with registered DIMM technology for compatible server systems.
- Single-Rank 1Rx4 Design: Uses a single-rank memory organization with x4 DRAM devices.
- 288-Pin, 1.1V Design: Features a 288-pin DIMM form factor and nominal operating voltage of 1.1V.

Server Compatibility
The Samsung M321R4GA0PB0-CWM is designed for systems that support DDR5 ECC Registered DIMMs. Before installation, check the server manufacturer's documentation to confirm support for this exact part number, memory capacity, rank organization, and transfer rate.
Actual operating speed may depend on the installed processor, server motherboard, firmware, and memory configuration. DDR5 RDIMMs are not interchangeable with DDR4 memory or standard unbuffered desktop DIMMs.
DC Supplies Product Note
DC Supplies recommends verifying the exact part number, M321R4GA0PB0-CWM, against your server's compatibility documentation before purchasing. Confirm that your system supports 32GB DDR5-5600 ECC registered memory with a single-rank 1Rx4 organization.
