Compatibility Information
This module is a DDR5 ECC Registered DIMM (RDIMM). It is not interchangeable with standard desktop unbuffered DIMMs (UDIMMs) or laptop SO-DIMMs. The host system must explicitly support DDR5 registered memory, 96GB DIMM capacity, and the module's rank and DRAM organization.
The actual operating speed may depend on the server model, processor, firmware, and memory population configuration. Check the server manufacturer's memory compatibility list before purchasing or installing this module.
DC Supplies Product Note
DC Supplies recommends checking the exact part number against your server's memory requirements before ordering. Confirm support for 96GB DDR5-5600 ECC RDIMMs with dual-rank 2Rx4 organization to help ensure compatibility with your system.
Frequently Asked Questions
1. What is the capacity of the Samsung M321RYGA0PB0-CWM?
This Samsung server memory module has a capacity of 96GB.
2. What is the rated speed of this memory?
It is rated for DDR5-5600 operation, with a transfer rate of 5600 MT/s and a PC5-44800 classification. Actual operating speed depends on the host system's supported memory 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 memory module using x4 DRAM organization. Check the server manufacturer's documentation to confirm support for this configuration.
5. Can I use this module in a standard desktop PC?
Generally, no. Most standard desktop systems use unbuffered memory rather than registered server DIMMs. The motherboard and processor must explicitly support DDR5 RDIMM memory.
6. Will this module run at 5600 MT/s in every server?
Not necessarily. Supported memory speeds depend on the server platform, processor, firmware, and DIMM population rules. Consult the manufacturer's documentation to confirm compatibility and supported speeds.
