HPE P16001-001 128GB DDR4-2933 Server Memory Kit

HPE P16001-001 128GB DDR4-2933 Load Reduced Spare Memory

HPE P16001-001 is the service spare number for the 128GB Quad Rank x4 DDR4-2933 load reduced DIMM used in ProLiant Gen10 servers. HPE’s parts description for it reads SPS-DIMM,128GB PC4-2933Y-L,4Gx4, which in plain terms means a 128GB spare DIMM rated PC4-2933, load reduced, built from 4Gb x4 DRAM organisation.

Spare numbers are what HPE engineers and support cases use when a part needs replacing, so P16001-001 is often the number quoted after a memory fault. It is the same module that is sold as option kit P11040-B21 and labelled with assembly number P11057-0A1.

New and Refurbished versions are listed here, subject to stock. The applicable warranty is shown when you choose either one.

Key Features At A Glance

• HPE spare part for 128GB Gen10 LRDIMMs
• Same module as option kit P11040-B21
• Load reduced, quad rank, x4 organisation
• PC4-2933Y-L rating with ECC
• Ideal for replacing a failed DIMM like for like
• New or Refurbished availability, depending on stock

Why a -001 Spare Number Exists

HPE manages its parts in two streams. Option kits with a -B21 suffix are sold as upgrades and appear in QuickSpecs. Spare parts with a -001 suffix are used by HPE service for repairs, and they are the numbers you will see in support case notes and in HPE PartSurfer. The physical DIMM also carries an assembly number on its label, which for this module is P11057-0A1.

Because spare and option numbers refer to the same module, P16001-001 can be ordered to replace a failed P11040-B21, and it can also be added to a server that already uses that kit, provided the population rules are followed.

Replacing a Failed 128GB DIMM

When a Gen10 server reports a memory error, the Integrated Lights-Out (iLO) management processor and the server event logs normally identify the affected DIMM slot. Before you order, note the slot, the label details of the failed module and the server serial number. The replacement should match the failed module in capacity, type and rank, which means another 128GB 4Rx4 LRDIMM such as P16001-001. Do not substitute a registered DIMM or a 3DS LRDIMM like the 128GB octal rank P00928-B21, because HPE does not allow those types to be mixed with this module.

Processor and Speed Considerations

HPE listed the DDR4-2933 kits for Gen10 servers fitted with 2nd Gen Intel Xeon Scalable processors. Servers with first generation processors use the DDR4-2666 range. The final memory speed depends on the processor model and on the number of DIMMs per channel, so a 2933 rated module may run slower on some processors.

Why Use a Genuine HPE Spare

P16001-001 belongs to the HPE Smart Memory range. HPE system firmware recognises Smart Memory modules, and HPE states that some of its memory performance and management features are only available when genuine HPE memory is fitted. Using the original spare number therefore keeps the repaired server in the same state as before the fault, with the same module type that the rest of the memory already uses.

New HPE P16001-001

New stock is an unused spare, useful where a repair must use new parts or a server is still under a strict support policy. Its warranty is shown when New is selected.

Refurbished HPE P16001-001

Refurbished stock is a genuine HPE module that has been in service before. It offers a lower cost way to restore a server after a DIMM failure. The warranty for this choice appears on selection.

Frequently Asked Questions

Is P16001-001 a genuine HPE spare part number?

Yes. P16001-001 is the HPE spare number for the 128GB Quad Rank x4 DDR4-2933 LRDIMM. The matching option kit is P11040-B21 and the assembly number on the module is P11057-0A1.

Can P16001-001 replace a failed P11040-B21 module?

Yes. Both numbers describe the same 128GB load reduced DIMM, so P16001-001 is a like for like replacement.

Can I fit P16001-001 next to registered DIMMs?

No. It is an LRDIMM, and HPE does not support mixing load reduced and registered memory in the same server.

What warranty comes with this spare?

It depends on whether you choose New or Refurbished. The warranty for the selected option is displayed on this page.

Can you send P16001-001 to a UK address?
