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, 128GB DIMM capacity, and the relevant 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 compatibility list and installation guidance before purchasing or installing this module.
DC Supplies Product Note
DC Supplies recommends confirming the exact part number against your server's memory requirements before ordering. Verify support for 128GB 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 M321RAJA0MB0-CWM?
This Samsung server memory module has a capacity of 128GB.
2. What is the speed of this memory module?
It is rated for DDR5-5600 operation, with a data transfer rate of 5600 MT/s and a PC5-44800 classification. The actual operating speed depends on the host system's supported configuration.
3. Does this module support ECC?
Yes. The M321RAJA0MB0-CWM 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 your server's supported memory configurations before installation.
5. Can this module be installed in a standard desktop computer?
Generally, no. Most standard desktop computers use unbuffered memory rather than registered server DIMMs. 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 operating speed depends on the processor, server platform, firmware, and memory population rules. Consult the manufacturer's documentation to confirm compatibility and supported speeds.
