DIMM-Processor Compatibility - HPE ProLiant Gen10, Gen10 Plus and Gen11 servers

Posted by Team Server Builds on 1st Nov 2023

When setting up or upgrading a server, one of the most crucial components to consider is the Dual In-line Memory Modules (DIMMs). These modules, while integral to performance, must be compatible with the installed processor to ensure optimal function. Intel's Xeon Scalable Processors, known for their high-end performance, have specific compatibility requirements with DIMMs. This guide is designed to help you navigate these intricacies.


Matching Your DIMM to the Processor's Generation

The Intel Xeon Scalable Processor's generation installed in your server dictates the type of DIMM it can support. Below is a breakdown of this compatibility:

  1. First-generation Intel Xeon Scalable Processors: These support DDR4-2666 DIMMs. When using a server with this generation of processor, ensure you are exclusively utilizing DDR4-2666 DIMMs for optimal compatibility and performance.
  2. Second-generation Intel Xeon Scalable Processors: These are compatible with DDR4-2933 DIMMs. If your server houses this generation of processor, you should be integrating DDR4-2933 DIMMs.

Avoid Mixing DIMM Types

It's essential to underline that mixing different types of DIMMs within a server is not recommended. This mismatch can lead to operational issues and degrade overall server performance. Stick to the specific DIMM type recommended for your processor's generation, be it DDR4-2666 or DDR4-2933.


Conclusion

Ensuring the compatibility of DIMMs with the installed processor is paramount in maintaining a server's health, stability, and performance. As the world of servers evolves and processors continue to advance, understanding these nuances becomes even more pivotal.
