Service engineers and support cases usually refer to HPE memory by its spare number, and P20504-001 is the spare for the 64GB Dual Rank x4 DDR4-3200 CAS-22-22-22 registered DIMM used in AMD EPYC based ProLiant Gen10 Plus servers. Its option kit counterpart is P07650-B21, and the module label usually shows the assembly number P11446-1A1.
In other words, ordering P20504-001 gets you the same 64GB RDIMM as the retail kit, identified by the number HPE service uses. It is the natural choice when you are replacing a faulty DIMM in a DL325, DL365 or DL385 Gen10 Plus.
It is offered in New and Refurbished condition, subject to stock. Select a condition to see the price and the warranty that goes with it.
A -001 suffix tells you that P20504-001 comes from HPE’s spare parts list rather than its upgrade catalogue. The upgrade version is option kit P07650-B21, which is the number printed in the DL385 Gen10 Plus QuickSpecs. The module itself is usually labelled P11446-1A1. All three numbers point to the same 64GB 2Rx4 DDR4-3200 registered DIMM, so any of them can be used to find a match.
Intel Gen10 Plus servers use a different 64GB kit, P06035-B21, with its own spare number P21676-001. If your server is an Intel model, that is the pairing to look for.
HPE iLO logs normally show which slot holds a failing module. Replace it with the same type, capacity and rank, and keep the slot positions unchanged so the memory stays balanced across channels. P20504-001 is a registered DIMM, so it should only be used alongside other RDIMMs. HPE does not support mixing registered memory with load reduced modules such as the 128GB P07652-B21 or the 256GB 3DS P07654-B21.
The module is rated for 3200 MT/s. The speed it actually runs at is set by the EPYC processor fitted and by how many DIMMs share each channel, so a fully populated server may run memory more slowly than a lightly populated one. This is normal and does not indicate a fault.
Each AMD EPYC processor in these servers has eight memory channels, and the DL385 Gen10 Plus provides 16 DIMM slots per processor. One 64GB module per channel on a two processor server means 16 modules and 1TB of memory. Filling the second slot in every channel doubles that to 2TB, still using registered DIMMs. If you are adding to an existing build, try to keep the same number of modules on each processor.
Choose New for an unused spare, the usual choice for critical repairs or strict sourcing rules. The warranty for New stock is shown when selected.
Choose Refurbished for a genuine HPE module from previous service at a lower price, which is often the most economical way to restore a server to full memory. Its warranty is shown when selected.

It is the HPE spare part number for a 64GB Dual Rank x4 DDR4-3200 registered DIMM. The equivalent option kit is P07650-B21.
Intel Gen10 Plus servers such as the DL380 Gen10 Plus list the P06035-B21 kit, spare P21676-001, for 64GB. P20504-001 is listed for the AMD models, so contact us before ordering for an Intel server.
Yes. P11446-1A1 is the assembly number commonly found on the same module, so they are a direct match.
Refurbished is a previously used genuine HPE module sold at a lower price, while New is unused. The warranty for each is shown when you select it.
Yes. We deliver within the UK and you can choose from the options shown at checkout.
