What is maximum memory for DL380 Gen10 servers?

Posted by HPE Memory Specialist on Mar 07, 2021

We've had several customers inquire recently about maximum memory for ProLiant DL380 Gen10 servers.

The answer depends on a few other variables. These servers come with 12 slots for each CPU installed. Dual CPU servers can use all 24 slots. For purposes of this post, we'll assume you are working with a dual CPU configuration.

Load Reduced Memory (3.0 TB max)

If you are using Load Reduced (LRDIMM) memory, the maximum capacity would be 3.0 TB, which would consist of 24x 128GB modules (DDR4-2666) (DDR4-2933).

Registered Memory (1.54 TB max)

If you are using Registered (RDIMM) memory, your maximum would be 1.54 TB, via 24x 64GB modules. The most popular is the 32GB module, part number P00924-B21.

Intel Optane Persistent Memory (6.0 TB max)

As of this post, servers with select 2nd generation Intel Xeon Scalable Series Processors can use Intel Optane Persistent Memory modules. This allows for a maximum of 6.0 TB and would be accomplished by installing twelve (12) 512GB modules (835810-B21).

As always, feel free to contact Global One Technology with any questions about HPE server memory.
