HPE Server Memory (RAM) Upgrades

What type of RAM is compatible with HPE ProLiant servers?

Most HPE ProLiant servers use RDIMM or LRDIMM modules that meet JEDEC standards for enterprise performance and compatibility. Always match the module type, speed, and voltage listed in your server documentation.

How do I find compatible memory for my HPE server?

Use our memory configurator or browse by HPE ProLiant model to select fully compatible RDIMM, LRDIMM, or UDIMM modules for your server.

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.

Does installing third-party RAM void my HPE warranty?

No. Installing compatible memory does not void your warranty, as long as the modules meet OEM specifications for performance and compliance.
