HPE P21674-001 32GB DDR4-3200 Server Memory Kit

HPE P21674-001 32GB Dual Rank x4 DDR4-3200 Spare Memory

Listed by HPE service as the spare for its 32GB (1x32GB) Dual Rank x4 DDR4-3200 CAS-22-22-22 Registered Smart Memory Kit, P21674-001 is the number to use when a 32GB DIMM in an Intel based ProLiant Gen10 Plus server needs replacing. The matching option kit is P06033-B21 and the assembly number printed on the module is P11444-091.

The 32GB dual rank RDIMM is one of the most widely fitted sizes in Gen10 Plus servers, so this spare is often needed to restore a server to its original memory after a fault, or to add a matching module during an upgrade.

Both New and Refurbished options are offered, subject to stock, and the warranty for each is shown when you select it.

How P21674-001 Relates to Other 32GB Numbers

There are two 32GB Dual Rank x4 DDR4-3200 families in the Gen10 Plus generation, and their numbers are easy to mix up:

The modules share capacity, rank and speed, but HPE lists them in separate catalogues. This spare belongs to the Intel row. HPE also offers a 32GB single rank x4 kit, P40007-B21, for Intel Gen10 Plus, so a 32GB label alone is not enough to identify the right replacement.

Persistent Memory and Population Rules

The Intel Gen10 Plus servers can run Intel Optane Persistent Memory 200 Series alongside DDR4. In the DL380 Gen10 Plus QuickSpecs, HPE states that when persistent memory is fitted the DDR4 DIMMs must match in capacity and rank, that persistent memory is supported only on selected processors, and that it needs the Maximum Performance Fan Kit P14608-B21. Without persistent memory, the main rules are to install DIMMs in even quantities and not to mix RDIMMs with LRDIMMs. The processor sets the top memory speed, which may be 3200, 2933 or 2667 MT/s depending on the model.

Swapping Out a Faulty 32GB Module

Gen10 Plus servers record memory errors in the iLO event log, which names the processor and slot involved. Power the server down, remove the module from that slot and read its label before ordering, since the label confirms whether you need this Intel spare or the AMD equivalent. Fit the replacement in the same slot so that the channel layout does not change. After start up, iLO should show the module as healthy and the full memory total should be reported again. If the error returns in the same slot with a new module, the cause may lie elsewhere, such as the processor socket or system board, and it is worth contacting HPE support or our team.

New HPE P21674-001

An unused spare for repairs that must use new parts or for new deployments. Warranty terms appear when New is selected.

Refurbished HPE P21674-001

A genuine HPE module from previous service, priced below new. A sensible choice for replacing a failed DIMM or adding matching memory. The warranty shows when Refurbished is selected.

• Check the assembly suffix is -091, not -191.
• Confirm 32GB 2Rx4 PC4-3200 on the label.
• Confirm the server has 3rd Gen Intel Xeon Scalable processors.

Frequently Asked Questions

Which option kit is P21674-001 the spare for?

P21674-001 is the spare for option kit P06033-B21, the 32GB Dual Rank x4 DDR4-3200 registered kit. The module label usually shows P11444-091.

Is P21674-001 the same as P20503-001?

Both are 32GB 2Rx4 DDR4-3200 RDIMM spares, but P20503-001 belongs to the AMD Gen10 Plus kit P07646-B21, while P21674-001 belongs to the Intel kit P06033-B21.

Can I use P21674-001 with Optane persistent memory?

On supported Intel Gen10 Plus servers and processors, yes, but HPE requires the DDR4 DIMMs to match in capacity and rank, so all DDR4 modules should be the same type.

What condition and warranty options are there?

New and Refurbished, subject to stock. The warranty for each is shown on the product page when you select it.

Do you ship P21674-001 within the UK?
