Compatibility Information
This module is a DDR5 ECC Registered DIMM (RDIMM). It is not interchangeable with standard desktop UDIMMs or laptop SO-DIMMs. Your server must explicitly support DDR5 registered memory, the 64GB module capacity, and the module's memory organization.
The actual memory speed supported after installation may depend on the processor, motherboard, firmware, and overall memory configuration. Check the server manufacturer's documentation or qualified memory compatibility list before purchasing.
DC Supplies Product Note
DC Supplies recommends checking the complete part number against your server's memory requirements before ordering. Confirm that your system supports 64GB DDR5-5600 ECC RDIMM modules with dual-rank 2Rx4 organization to help ensure compatibility.
Frequently Asked Questions
1. What is the capacity of the Samsung M321R8GA0PB0-CWM?
This module has a capacity of 64GB and is designed for compatible server memory configurations.
2. What is the memory speed of this module?
It has a rated data transfer speed of 5600 MT/s and a PC5-44800 classification. The actual operating speed depends on the capabilities and configuration of the host system.
3. Does this Samsung memory support ECC?
Yes. It is an ECC registered memory module designed for compatible server platforms.
4. What does 2Rx4 mean?
The 2Rx4 designation indicates a dual-rank module using x4 DRAM organization. Check your server's supported memory configurations before installation.
5. Can this module be used in a standard desktop PC?
Generally, no. Standard desktop systems typically use unbuffered memory, while this module is a registered DIMM. The motherboard and processor must explicitly support DDR5 RDIMM memory.
6. Will this module operate at 5600 MT/s in every server?
Not necessarily. The supported memory speed depends on the server platform, processor, firmware, and DIMM population rules. Consult the manufacturer's specifications to determine the supported operating speed.
