Compatibility and Installation
The Samsung M321R4GA0PB2-CCP is intended for server systems that support DDR5 ECC Registered DIMMs. Before purchasing, check your server manufacturer's compatibility documentation to confirm support for this exact part number, memory capacity, rank configuration, and data transfer rate.
The actual operating speed may depend on the processor, server motherboard, firmware, and installed memory configuration. DDR5 RDIMMs are not interchangeable with DDR4 modules or standard unbuffered desktop memory.
DC Supplies Product Note
DC Supplies recommends confirming the exact MPN, M321R4GA0PB2-CCP, against your server's supported memory list before ordering. Verify that your system supports 32GB DDR5-6400 ECC registered memory with a single-rank 1Rx4 organization.
