HPE P11443-091 16GB DDR4-3200 Server Memory Kit

HPE P11443-091 16GB Dual Rank x8 DDR4-3200 Registered Memory

The number P11443-091 identifies a 16GB DDR4-3200 registered DIMM built with two ranks of x8 DRAM chips. It is the assembly number for the module HPE sells as the 16GB (1x16GB) Dual Rank x8 DDR4-3200 CAS-22-22-22 Registered Smart Memory Kit, option P06031-B21, with HPE service spare P21673-001.

This 16GB size is a sensible entry point for Intel based ProLiant Gen10 Plus servers, where it lets you fill every memory channel without paying for capacity you do not need yet. It also makes a good like for like replacement when one DIMM in a running server reports errors.

P11443-091 is available here as New or Refurbished, subject to stock. Each option shows its own price and warranty once selected.

Key Features At A Glance

• 16GB registered ECC DDR4 module
• 3200 MT/s rating for 3rd Gen Xeon Scalable servers
• Dual rank built from x8 DRAM devices
• Same module as option kit P06031-B21
• HPE Smart Memory for Gen10 Plus platforms
• Choice of New or Refurbished condition

Understanding the -091 Suffix

Unlike the -B21 suffix, which marks a kit that you order, and the -001 suffix, which marks a service spare, a number ending in -091 is an assembly number. It describes the physical module and is what you usually see printed on the DIMM label. For this memory the three numbers line up as follows: P06031-B21 option kit, P21673-001 spare, P11443-091 assembly.

HPE also lists P21673-001 as the spare behind P43168-B21, a 16GB Dual Rank x8 DDR4-3200 kit sold in the factory integrated (FIO) range. That is why you may see the same spare tied to two option numbers. The module type is the same, but the option number you order depends on whether the memory is bought separately or as part of a factory build.

Dual Rank x8 Versus Single Rank x4

HPE offers two different 16GB DDR4-3200 registered kits for Intel Gen10 Plus. P06031-B21 (this module) is dual rank x8, while P06029-B21 is single rank x4. Both have the same capacity and speed, but their internal layout differs, so for a consistent configuration keep the same type across each processor. The AMD Gen10 Plus servers list their own 16GB Dual Rank x8 kit, P07642-B21, rather than P06031-B21.

Speed and Population Guidance

According to the DL380 Gen10 Plus QuickSpecs, HPE DDR4-3200 kits can run at 3200 MT/s with one or two DIMMs per channel, but the processor sets the ceiling. Some Gold and all Silver 3rd Gen Xeon Scalable processors run memory at 2933 or 2667 MT/s. HPE asks for DIMMs to be installed in even quantities and does not allow RDIMMs to be mixed with LRDIMMs.

As a worked example, the DL380 Gen10 Plus has eight memory channels per processor and 16 slots per processor. Fitting one 16GB module in every channel on a two processor server takes 16 modules and gives 256GB, leaving the second slot in each channel free for later growth.

New P11443-091 Memory

Pick New for an unused module, for example when adding memory to a new server. Warranty and condition details are displayed for the New option on this page.

Refurbished P11443-091 Memory

Refurbished modules are previously used genuine HPE parts at a lower price, a good fit for replacing a faulty DIMM or adding memory to an older deployment. The warranty is listed when you select Refurbished.

Is This the Right Module?

• Check the DIMM label for P11443-091, or the box for P06031-B21.
• Look for 16GB 2Rx8 and a 3200 speed marking on the label.
• Confirm the server is an Intel Xeon Gen10 Plus model.
• Keep to registered DIMMs only in that server.

Frequently Asked Questions

What is the option kit number for P11443-091?

The option kit is P06031-B21 and the HPE spare is P21673-001. P11443-091 is the assembly number usually printed on the module itself.

Can I mix P11443-091 with 16GB single rank x4 modules?

Both are 16GB DDR4-3200 RDIMMs, but they have different internal layouts. For a consistent configuration, use the same rank and organisation across each processor and check the HPE population guidance.

Will this 16GB module run at 3200 MT/s in every Gen10 Plus server?

Not always. The processor decides the maximum memory speed, and some 3rd Gen Xeon Scalable models limit memory to 2933 or 2667 MT/s.

What warranty applies to New and Refurbished stock?

The warranty differs by condition and is shown on the product page when you select New or Refurbished.
