HPE 850883-001 128GB DDR4-2666MHZ Memory

HPE 850883-001 128GB DDR4-2666 LRDIMM Spare Part

HPE 850883-001 is the service spare number for a 128GB DDR4-2666 load reduced memory module used in ProLiant Gen10 servers. It matches HPE option kit 815102-B21, and the module itself carries assembly code 840760-091 on its label.

Spare numbers ending in -001 are what HPE support engineers quote when a failed part is replaced under a service call. If a support case or a parts list names 850883-001, this is the module it refers to.

We stock the 850883-001 in both New and Refurbished condition, subject to availability.

Key Features At A Glance

• HPE service spare for the 128GB 815102-B21 kit
• Very high per-slot capacity for memory heavy workloads
• 3DS stacked DRAM on a load reduced module
• Made for ProLiant Gen10 with Intel Xeon Scalable processors
• ECC protection and HPE SmartMemory
• New or Refurbished, depending on stock

When to Choose the 850883-001

The most common reason to order this part is a like-for-like swap. If one 128GB DIMM in a Gen10 server reports errors, replacing it with the same spare keeps every channel matched. It is also used to complete a partly filled server that already runs 128GB modules.

For capacity planning, a dual processor DL380 Gen10 has 24 DIMM slots, so 128GB modules take that server to the highest totals it can reach with this generation of memory. Large virtualisation hosts, in-memory databases and analytics servers are typical users.

Installation Notes

Power the server down and disconnect it before opening the access panel, and use an anti-static strap when handling the module. Fit the replacement in the same slot as the module you removed, then check the memory status in the server’s management interface after boot. If the system reports a configuration warning, compare the slot layout with the HPE population guide for your model, as uneven channel loading can lower performance.

How It Differs From Nearby Parts

Several HPE modules look similar on a parts list, so it helps to separate them:

• 850883-001 / 815102-B21: 128GB, octal rank (8Rx4) 3DS LRDIMM at DDR4-2666 with CL22 timings. This part.
• 850882-001 / 815101-B21: the 64GB quad rank DDR4-2666 LRDIMM from the same Gen10 range.
• P11040-B21: a 128GB quad rank DDR4-2933 LRDIMM introduced for servers with second generation Xeon Scalable processors.

Whichever you choose, keep a server to one memory type. HPE does not support combining load reduced and registered DIMMs.

New 850883-001 Module

New means an unused module. The price and warranty for this condition appear when you pick the New option.

Refurbished 850883-001 Module

Refurbished modules have been in service before and are offered for less, which can make a large 128GB upgrade easier to budget. Select the option to see its condition notes and warranty.

Frequently Asked Questions

What is the option kit number for 850883-001?

The matching option kit is 815102-B21. Both numbers describe the same 128GB DDR4-2666 LRDIMM, which carries assembly number 840760-091 on its label.

Can I replace one faulty 128GB DIMM with this spare?

Yes, that is its main use. Fitting the same 850883-001 module keeps the channel matched with the rest of the 128GB LRDIMMs in the server.

Should I use 850883-001 or P11040-B21 in my Gen10 server?

The 850883-001 is the DDR4-2666 module from the original Gen10 range, while P11040-B21 is a DDR4-2933 kit for second generation Xeon Scalable processors. Match the memory already installed, or send us your server details to check.
