HPE P38520-1A1 32GB DDR4-3200 Memory Kit

HPE P38520-1A1 32GB DDR4-3200 Single Rank Registered Module

If you have pulled a memory module from an HPE Gen10 Plus server and found P38520-1A1 printed on the label, this is the matching part. P38520-1A1 is the HPE assembly number for a 32GB registered DDR4 DIMM rated at 3200 MT/s, built as a single rank x4 module.

The assembly number identifies the physical module rather than how it was sold. The same module is supplied under option kit number P38454-B21 and spare number P39381-001, so ordering by the label number simply lets you match like for like without having to look anything up.

We can supply P38520-1A1 in New or Refurbished condition, subject to stock. Select the condition you need on this page to see the price and details.

Why HPE Memory Carries An Assembly Number

HPE parts often have three identities. The -B21 option number is used for upgrades and factory builds, the -001 spare number is used by HPE service for replacements, and a manufacturing or assembly number such as P38520-1A1 is printed on the part itself. The assembly number is usually the one an engineer reads first when the server lid comes off, which is why many replacement orders start with it.

For P38520-1A1, resellers cross-reference the assembly number to P38454-B21 and P39381-001, and the spare description reads 32GB PC4-3200AA-R 4Gx4. That last part tells you the module uses x4 DRAM organisation and registered buffering, which is what you need to match in an existing bank of memory.

Matching It To The Memory Already In Your Server

When you are replacing one failed DIMM, the safest choice is an identical module. HPE servers in this family do not support mixing x4 and x8 modules, and RDIMMs cannot share a server with LRDIMMs. Matching the rank also matters, because many older 32GB DDR4 modules are dual rank, while P38520-1A1 is single rank.

If you are adding memory rather than replacing it, fill channels evenly across both processors and follow the population order printed on the server’s access panel label or in its user guide. On the DL385 Gen10 Plus, HPE quotes 3200 MT/s at one or two DIMMs per channel for kits from 8GB to 128GB, with the actual speed also depending on the CPU.

Before swapping a module, power the server down, disconnect the power cords and use an anti-static strap. Release the DIMM slot latches, lift the old module straight out and press the new one in evenly until the latches close. On boot, the server firmware should report the full installed capacity, and the Integrated Management Log will record any memory error if a module is not seated correctly.

Frequently Asked Questions

What does the P38520-1A1 number on my memory label mean?

It is the HPE assembly number for the physical module. The same 32GB single rank DDR4-3200 module is also sold as option kit P38454-B21 and spare P39381-001.

Can I replace a dual rank 32GB DIMM with P38520-1A1?

It is better to match like with like. P38520-1A1 is single rank, so if the rest of your server uses dual rank 32GB modules, choose a matching dual rank part instead.

Which HPE servers use the P38520-1A1 module?

Its option kit appears in HPE memory options for the DL385 Gen10 Plus, and resellers also list the DL325, DL365 and DX385 Gen10 Plus. Send us your model if you need it checked.
