Compatibility Information
The Samsung M321R8GA0PB2-CCP is a DDR5 ECC Registered DIMM. It is not interchangeable with standard unbuffered desktop UDIMMs or laptop SO-DIMMs. The host server must support DDR5 registered memory, the module capacity, and the relevant rank and DRAM organization.
The actual operating speed may depend on the server model, processor, firmware, memory population, and supported memory configurations. Check the server manufacturer's documentation or compatibility list before purchasing or installing the module.
DC Supplies Product Note
DC Supplies recommends verifying the complete part number against your server's memory requirements before ordering. Confirm support for 64GB DDR5-6400 ECC RDIMMs with dual-rank 2Rx4 organization to help ensure a suitable match for your system.
Frequently Asked Questions
1. What is the capacity of the Samsung M321R8GA0PB2-CCP?
This Samsung server memory module has a capacity of 64GB.
2. What speed does this module support?
It is rated for DDR5-6400 operation, with a transfer rate of 6400 MT/s and a PC5-51200 classification. Actual speed depends on the host system's capabilities and configuration.
3. Does this module support ECC?
Yes. It is an ECC registered DIMM 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 memory support documentation before installation.
5. Can I use this module in a standard desktop PC?
Generally, no. Most standard desktop motherboards use unbuffered memory rather than registered server DIMMs. The motherboard and processor must explicitly support DDR5 RDIMM memory.
6. Will this module run at 6400 MT/s in every server?
No. The supported operating speed depends on the processor, server platform, firmware, and memory population rules. Consult the manufacturer's documentation to confirm the supported speed.
