Server Memory Compatibility
Guide to server memory compatibility for Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro servers. Understand DDR4 and DDR5 RDIMM, LRDIMM requirements.
Key Considerations
- ECC (Error-Correcting Code) is required for all server platforms
- Registered DIMMs (RDIMM) or Load-Reduced DIMMs (LRDIMM) for multi-socket systems
- Speed grades must match or exceed the CPU's supported memory frequency
- Mixing ranks and densities may reduce effective speed
