HPE P28217-B21 64GB DDR4 Memory Kit

HPE P28217-B21 Synergy 64GB Dual Rank x4 DDR4-2933 Registered Memory Kit

The HPE P28217-B21 is a 64GB DDR4-2933 registered memory kit catalogued for HPE Synergy compute modules. Distributor listings describe it as the HPE Synergy 64GB 2Rx4 DDR4-2933 memory kit, a single 64GB dual rank x4 RDIMM with CAS-21-21-21 timings, and name the Synergy 480 Gen10 and Synergy 660 Gen10 as the target systems.

Because it is a Synergy option rather than a general ProLiant kit, it is mostly needed by teams running Synergy frames who want to expand or repair compute module memory with a kit number that matches their existing records. Major distributors now list the kit as discontinued, which makes stock from the spares market the usual source.

We list P28217-B21 as New or Refurbished, subject to stock. The warranty and condition details for each appear when you pick an option.

Key Features At A Glance

• 64GB registered ECC DDR4 on one DIMM
• Catalogued for HPE Synergy Gen10 compute modules
• Dual rank, x4 DRAM organisation
• Rated for DDR4-2933 operation
• HPE Smart Memory
• Available New or Refurbished, subject to stock

A Synergy Option Kit, Not a Gen10 Plus Part

The -B21 suffix shows that P28217-B21 is an HPE option kit, the number used to order an upgrade. What sets it apart from the other 64GB kits on our site is the platform. It is a DDR4-2933 kit for Synergy Gen10 compute modules, the generation that uses Intel Xeon Scalable processors. It is not a DDR4-3200 part, so it does not belong to the Gen10 Plus memory ranges used by servers such as the DL385 Gen10 Plus or the Synergy 480 Gen10 Plus.

For ProLiant Gen10 rack and tower servers, HPE’s general 64GB Dual Rank x4 DDR4-2933 registered kit is P00930-B21. The two kits have the same headline specification. If your paperwork or the existing memory shows P28217-B21, ordering the same number is the simplest way to keep a Synergy configuration consistent.

Processor and Population Notes

HPE’s DDR4-2933 memory was listed for Gen10 systems with 2nd Gen Intel Xeon Scalable processors, with the DDR4-2666 range used for first generation processors. Actual memory speed depends on the processor model and DIMM count per channel. As a registered DIMM, P28217-B21 should not be combined with LRDIMMs in the same compute module, and memory should be spread evenly across the channels of each processor.

Fitting Memory in a Synergy Compute Module

Unlike a rack server, a Synergy compute module lives inside a Synergy frame and shares its power, cooling and management. To add or replace memory, the compute module is powered off through HPE OneView or the module controls, pulled from the frame and opened on a clean, static safe surface. Once the DIMMs are fitted in the correct slots, the module goes back into the same bay. Planning the work around a maintenance window keeps disruption to workloads to a minimum.

New HPE P28217-B21

The New option is an unused kit for planned expansion or repairs that require new parts. Warranty details for New appear when it is selected.

Refurbished HPE P28217-B21

The Refurbished option is a genuine HPE module with previous service history, offered for less. It is a good way to match the memory already fitted in a Synergy compute module. Its warranty is shown when selected.

Making Sure It Matches

• Check your records or the existing kit box for P28217-B21.
• Confirm the module label shows 64GB 2Rx4 and a 2933 rating.
• Confirm the compute module is a Synergy Gen10 model, not Gen10 Plus.
• Make sure the other DIMMs are registered, not load reduced.

Frequently Asked Questions

Which systems is P28217-B21 intended for?

Distributor listings name the HPE Synergy 480 Gen10 and Synergy 660 Gen10 compute modules. It is a DDR4-2933 kit for the Gen10 generation.

Can P28217-B21 be used in a Synergy 480 Gen10 Plus?

The Synergy 480 Gen10 Plus uses HPE DDR4-3200 memory kits such as P06033-B21, so P28217-B21 is not the kit listed for it. Contact us for the right Gen10 Plus part.

How does P28217-B21 compare with P00930-B21?

Both are 64GB Dual Rank x4 DDR4-2933 registered kits. P00930-B21 is the general ProLiant Gen10 kit, while P28217-B21 is catalogued as a Synergy memory kit.

What do I get with the Refurbished option?

A previously used genuine HPE module at a lower price than new. The warranty for Refurbished, and for New, is shown when you select the option.

Is P28217-B21 available for UK delivery?

Yes. We deliver across the UK and the options are displayed at checkout.
