HPE P39381-001 32GB DDR4-3200 Memory Kit

HPE P39381-001 32GB PC4-3200AA-R Spare Memory Module

P39381-001 is the HPE spare part number for a 32GB registered DDR4 module. HPE service uses spare numbers like this when a failed DIMM is swapped under a support contract, which is why you will often see it quoted on service tickets, in the HPE parts lookup or on replacement packaging.

Its spare description, SPS-DIMM 32GB PC4-3200AA-R 4Gx4, packs a lot of information into one line. It tells you the module is a 32GB registered DIMM, runs at 3200 MT/s and is built from x4 DRAM chips. The same physical module is sold as option kit P38454-B21 and carries assembly number P38520-1A1 on its label.

P39381-001 is listed here as New and Refurbished, depending on stock. Select a condition to see the price and details for it.

Key Features At A Glance

• HPE spare number used for like for like replacements
• 32GB DDR4 RDIMM with ECC error correction
• Single rank x4 build, as shown by its 1Rx4 rating
• Interchangeable with option P38454-B21 and assembly P38520-1A1
• New or Refurbished choice, subject to stock

Reading The Spare Description

Each part of SPS-DIMM 32GB PC4-3200AA-R 4Gx4 has a meaning:

• SPS marks it as an HPE spare part, not a retail option kit
• 32GB is the capacity of the single module
• PC4-3200AA is the DDR4 speed and timing grade, 3200 MT/s with CL22 timings
• R means registered, so it is an RDIMM rather than an LRDIMM or unbuffered module
• 4Gx4 describes the DRAM organisation, using x4 chips

When you compare this with the label on a failed module, check that the speed grade, the R suffix and the rank layout all match. A 32GB module that reads 2Rx4 is dual rank and is not an exact match, even though the capacity is the same.

Spare and option numbers matter more when you are buying for a fleet of servers. Procurement teams often order by the -B21 option number for new builds and by the -001 spare number for repairs, but in this case both arrive as the same module, so you can stock one part to cover both jobs.

Diagnosing A Failed DIMM Before You Replace It

HPE ProLiant servers log memory faults in the Integrated Management Log, which you can read through iLO. The log entry normally names the processor and slot of the affected DIMM, so you can find the right module without guessing. Reseat the module first if the log shows a one-off error, and replace it if errors keep returning on the same slot.

Keep the replacement in the same slot, and do not mix it with x8 modules or LRDIMMs, which HPE does not support alongside RDIMMs on the DL385 Gen10 Plus. On that platform HPE rates kits from 8GB to 128GB at 3200 MT/s with one or two DIMMs per channel, though the processor installed still sets the final speed.

Frequently Asked Questions

Is P39381-001 the same as P38454-B21?

Yes, they are the same 32GB single rank DDR4-3200 registered module. P39381-001 is the spare number used for replacements and P38454-B21 is the option kit number used for upgrades.

How do I find which DIMM has failed in my ProLiant?

Check the Integrated Management Log in iLO. It records memory errors and usually names the processor and slot, so you know which module to replace.
