96GB High-Capacity Memory
With 96GB in a single DIMM, the M321RYGA0PB0-CWM provides substantial memory density for compatible server platforms.
This capacity can help expand system RAM while preserving additional DIMM slots for future upgrades, depending on the server’s architecture and memory population requirements.
Suitable workloads include:
- Server virtualization
- Database applications
- Cloud infrastructure
- Enterprise applications
- Data analytics
- High-performance computing
- AI and compute infrastructure
- Storage servers
- Professional workstation workloads
Actual maximum memory capacity depends on the server, processor, BIOS/firmware, and supported DIMM configuration.
DDR5-5600 Performance
The module operates at DDR5-5600, providing a rated data-transfer rate of 5600 MT/s.
This makes the module suitable for modern server processors and memory-intensive applications requiring high memory bandwidth.
Actual operating frequency can vary according to:
- Server model
- CPU memory controller
- BIOS/firmware
- Number of installed DIMMs
- DIMM population
- Memory-channel configuration
- Server manufacturer specifications
A compatible server may operate the memory at a lower supported speed depending on its configuration.
ECC Error Correction
The M321RYGA0PB0-CWM is ECC memory, providing error detection and correction capabilities intended to improve memory reliability and data integrity.
ECC RDIMM memory is particularly appropriate for:
- Enterprise servers
- Virtualization hosts
- Database servers
- Storage systems
- Data-center infrastructure
- Cloud platforms
- High-performance computing
- Mission-critical applications
The exact part is identified as ECC/Registered memory in current technical listings.
Registered DIMM Architecture
The M321RYGA0PB0-CWM uses Registered DIMM (RDIMM) architecture.
RDIMM technology uses a register to buffer command and control signals, allowing compatible server platforms to support high-density memory configurations.
RDIMM, UDIMM, and SODIMM are different memory technologies and are not interchangeable.
The target server must specifically support DDR5 ECC RDIMM memory.
Dual-Rank 2Rx4 Organization
This module uses a dual-rank 2Rx4 organization.
| Memory Characteristic | Specification |
|---|---|
| Capacity | 96GB |
| Rank Configuration | 2R |
| Data Organization | x4 |
| Module Organization | 2Rx4 |
| DRAM Organization | 4G × 4 |
| DRAM Packages | 40 FBGA |
The rank and organization should be considered when configuring multiple DIMMs because server platforms can have specific memory population requirements.
288-Pin DDR5 DIMM
The Samsung M321RYGA0PB0-CWM uses a 288-pin DDR5 DIMM form factor.
However, 288-pin compatibility alone does not guarantee system compatibility. The server must also support:
- DDR5 memory
- ECC
- RDIMM architecture
- 96GB DIMMs
- 2Rx4 organization
- DDR5-5600 operation
- The required memory-channel configuration
Server & Data-Center Applications
The M321RYGA0PB0-CWM is designed for professional computing environments requiring high memory capacity and bandwidth.
Recommended applications include:
- Enterprise servers
- Data-center infrastructure
- Virtualization hosts
- Database servers
- Cloud computing
- AI and compute servers
- Storage systems
- Network infrastructure
- High-performance computing
- Engineering workstations
- Professional applications
ASUS qualification documents specifically identify the exact M321RYGA0PB0-CWM as a 96GB DDR5-5600 RDIMM, 288-pin module for supported server platforms.
Memory Population & Configuration
For multi-DIMM configurations, installation should follow the server manufacturer’s recommended DIMM population sequence.
For predictable performance and compatibility, it is recommended to match:
- Capacity
- Memory technology
- Speed
- Rank
- Organization
- ECC configuration
- Manufacturer
- Part number
The actual memory speed is ultimately determined by the server platform, processor, DIMM population, and BIOS/firmware.
Compatibility Considerations
Before purchasing or installing the M321RYGA0PB0-CWM, verify that the target system supports:
- DDR5 ECC RDIMM
- 96GB DIMMs
- DDR5-5600
- 2Rx4 memory organization
- 288-pin DDR5 DIMMs
- The required DIMM population configuration
The exact part number has been qualified for specific ASUS server platforms, but qualification on one platform does not guarantee universal compatibility with every DDR5 server.

Important Compatibility Note
The Samsung M321RYGA0PB0-CWM is a 96GB DDR5 ECC RDIMM and should be marketed specifically as server memory.
It is not a standard consumer DDR5 desktop DIMM.
RDIMM, UDIMM, and SODIMM memory technologies are different and generally cannot be substituted for one another.
Always verify the target server’s:
- Server model
- CPU generation
- Motherboard
- BIOS/firmware
- Maximum supported memory
- RDIMM support
- DIMM population rules
- Supported memory frequency
- Rank and organization requirements
