HPE Server Memory FAQs

How do I know which HPE server memory is compatible with my model?

Check your server's technical documentation or use our Select Your Model filter to find compatible memory. If unsure, contact our support team for personalized guidance.

What is the difference between RDIMM, LRDIMM and UDIMM for HPE servers?

RDIMM (Registered DIMM)
Uses a register to buffer data signals before they reach the memory controller, reducing electrical load and improving signal integrity.
Common in server environments that need moderate‐to‐high memory capacities with stable performance.
LRDIMM (Load‐Reduced DIMM)
Employs advanced buffering techniques to further reduce electrical load on the controller.
Ideal for high‐capacity server setups, as it allows more memory to be installed without overwhelming the memory bus.
UDIMM (Unbuffered DIMM)
Lacks any register or buffer, so signals go directly to the memory controller.
Typically used in desktops or smaller servers; cost‐effective but less scalable for large memory configurations compared to RDIMM or LRDIMM.

Can I mix memory sizes or speeds in my HPE server?

Yes, you can mix different memory sizes or speeds, but your server generally defaults to the lowest speed. Each module’s full capacity is typically recognized, but mixing can disrupt optimal performance. For best results, install identical modules (same size, speed, and type).

Do HPE servers require ECC memory?

Yes, most enterprise‐grade HPE servers rely on ECC (Error‐Correcting Code) memory to detect and correct data errors, ensuring reliability in mission‐critical environments. In fact, ECC is standard in many enterprise server deployments because it helps minimize data corruption and system downtime.

How many DIMMs should I install per CPU in my HPE server?

The ideal number depends on your server model and workload. For best performance, follow channel balancing and optimal population guidelines—usually specified in your server’s documentation. Distributing DIMMs evenly across memory channels helps maximize throughput, efficiency, and overall system stability.

Can I upgrade my HPE server’s memory without affecting its warranty?

Yes. Most manufacturers allow memory upgrades as long as you use modules that meet the server’s official specifications. Check your HPE server manual for approved speeds, capacities, and ECC requirements.

What are the benefits of upgrading HPE server memory?

Increasing memory capacity and speed can boost data transfer rates, support more virtual machines, and reduce bottlenecks in data‐intensive workloads.
