HPE P07650-B21 64GB DDR4-3200 Memory

HPE P07650-B21 64GB Dual Rank x4 DDR4-3200 Registered Smart Memory Kit

The HPE P07650-B21 is the option kit number for a single 64GB DDR4-3200 registered DIMM from the HPE Smart Memory range. HPE describes it as a 64GB (1x64GB) Dual Rank x4 DDR4-3200 CAS-22-22-22 Registered Smart Memory Kit, and it appears in the memory options for the AMD EPYC based ProLiant Gen10 Plus servers, such as the DL385 Gen10 Plus.

A 64GB RDIMM is a common choice when a server needs a large amount of memory without moving to load reduced modules. Two ranks of x4 DRAM chips keep the module on the standard registered platform, so it can sit alongside other HPE DDR4-3200 RDIMMs of the same type in a balanced configuration.

Euroland IT Store lists the P07650-B21 in New and Refurbished condition, subject to stock. Pick the condition you need on this page to see the price and the terms that apply to it.

Key Features At A Glance

• 64GB of ECC registered DDR4 on one DIMM
• Rated at DDR4-3200 for current Gen10 Plus platforms
• Dual rank, x4 chip layout for high density RDIMM builds
• HPE Smart Memory, recognised by HPE system firmware
• Sold as the -B21 option kit for AMD Gen10 Plus servers
• Available New or Refurbished, depending on stock

Option Kit, Spare and Assembly Numbers

HPE gives one memory module several part numbers depending on how it is sold. P07650-B21 is the option kit number, the one used when the memory is ordered as an upgrade or quoted in a QuickSpecs document. The same 64GB module is supplied as a service spare under P20504-001, and the label on the DIMM itself often carries the assembly number P11446-1A1. Specialist spares listings tie all three numbers to the same 64GB Dual Rank x4 DDR4-3200 registered module.

In practice this means an existing server may show the spare or assembly number when you open it up, while purchase records show P07650-B21. Any of the three numbers is a valid way to identify a replacement.

Why AMD and Intel Gen10 Plus Use Different Kits

HPE split its DDR4-3200 memory catalogue for Gen10 Plus. The AMD EPYC servers list kits in the P076xx series, while the Intel Xeon Gen10 Plus servers such as the DL360 and DL380 Gen10 Plus list kits in the P060xx series. The 64GB Dual Rank x4 option in the Intel QuickSpecs is P06035-B21, not P07650-B21.

Because the two catalogues are separate, check your server’s QuickSpecs before mixing numbers. If you are topping up a DL325, DL365 or DL385 Gen10 Plus that already carries P07650-B21 or P20504-001 modules, matching that number keeps the configuration within HPE’s tested list.

Population and Speed Notes

This is an RDIMM, so it should not be mixed with LRDIMMs such as the 128GB P07652-B21 or with 3DS modules in the same server. HPE also recommends balanced population across the memory channels of each processor. Rated speed is 3200 MT/s, but the final running speed depends on the processor model and the number of DIMMs fitted per channel, so the system may set a lower speed in some configurations.

New HPE P07650-B21 Memory

Choose the New option when you need an unused module, for example for a fresh build or where your procurement policy requires new parts. Condition and warranty details are shown when the New option is selected.

Refurbished HPE P07650-B21 Memory

The Refurbished option is a previously used genuine module that offers a lower cost route to the same capacity. It suits expansion of existing servers and spare stock. The warranty for this option is shown when you select it on the product page.

How to Confirm It Is the Right Module

• Look for P07650-B21, P20504-001 or P11446-1A1 on the existing DIMM label or in your order history.
• Check that the label shows 64GB, 2Rx4 and a DDR4-3200 rating.
• Confirm the server is an AMD Gen10 Plus model that lists the P076xx kits.
• Make sure the server is not populated with LRDIMMs.

Frequently Asked Questions

Is P07650-B21 the same module as P20504-001?

Yes. P07650-B21 is the option kit number and P20504-001 is the HPE spare number for the same 64GB Dual Rank x4 DDR4-3200 registered DIMM. The module label may also show the assembly number P11446-1A1.

Can I use P07650-B21 in a DL380 Gen10 Plus?

The Intel based DL380 Gen10 Plus QuickSpecs list the P060xx kits, with P06035-B21 as the 64GB Dual Rank x4 option. P07650-B21 is listed for the AMD Gen10 Plus models, so please contact us before using it in an Intel system.

Can this RDIMM be installed with 128GB LRDIMMs?

No. HPE does not support mixing registered and load reduced DIMMs in the same server, so use P07650-B21 only alongside other registered modules.

How do the New and Refurbished options differ?

New is an unused module. Refurbished is a previously used genuine HPE module offered at a lower price. Condition and warranty for each are shown when you select the option.

Do you ship this memory kit within the UK?

Yes, we deliver across the UK and the available delivery options are displayed at checkout.
