HPE 868843-001 PC4-21300 DDR4-2666MHz Memory

HPE 868843-001 32GB DDR4-2666 Registered Memory Spare

Spare number 868843-001 identifies a 32GB dual rank PC4-2666V registered DIMM supplied by HPE for service replacement. It pairs with option kit 838083-B21, the 32GB DDR4-2666 kit listed for AMD EPYC based ProLiant Gen10 servers, and the module label carries the assembly number 840758-191.

When an HPE support case or a parts breakdown names 868843-001, this is the replacement it refers to. Ordering by the spare number is the most reliable way to get exactly the module that was specified for the server.

Euroland IT Store has the 868843-001 in New and Refurbished condition, subject to stock levels.

Spare 868843-001 vs Spare 850881-001

HPE released two 32GB DDR4-2666 registered kits for Gen10 that are easy to mix up:

• 838083-B21 / 868843-001 / 840758-191: listed for AMD EPYC Gen10 servers. This part.
• 815100-B21 / 850881-001 / 840758-091: listed for Intel Xeon Scalable Gen10 servers such as the DL360 and DL380 Gen10.

Capacity, rank and speed are the same on paper, but each kit appears on a different set of server QuickSpecs. For a support replacement, match the spare number already recorded for your server rather than choosing on specification alone.

Memory Layout on DL325 and DL385 Gen10

First generation AMD EPYC processors have eight memory channels each, and these servers can take two DIMMs per channel. That gives the single socket DL325 Gen10 sixteen slots and the dual socket DL385 Gen10 thirty-two. Spreading modules evenly over all eight channels of each processor gives the best bandwidth, and every DIMM in the server should be the same type.

HPE QuickSpecs for the DL385 Gen10 also state that registered and load reduced DIMMs cannot be mixed, and that x4 and x8 based modules must not be mixed either. The 868843-001 is an x4 module, so do not combine it with x8 parts such as the 16GB 838089-B21 in the same server. Later DL385 Gen10 configurations with second generation EPYC processors use newer DDR4-2933 kits, so check which processors are fitted before adding memory.

The rated 2666 MT/s is a maximum. The processor model and the number of DIMMs in each channel decide the final speed.

Replacing a Failed Module

Use the server’s management log to find which slot reported the fault, then power the server down fully before opening it. Fit the new 868843-001 in the same slot, close the server and confirm after boot that the full memory size is reported and the error has cleared.

New 868843-001

An unused module is supplied under the New option. Its pricing and warranty appear when it is selected.

Refurbished 868843-001

A Refurbished module has seen previous service and is priced lower, making it a practical spare to keep on the shelf. The condition and warranty are listed once you select it.

Matching Checklist

• Compare the faulty module’s label with 868843-001, 838083-B21 or 840758-191.
• Check the marking reads 32GB 2Rx4 PC4-2666V-R.
• Confirm the server is a DL325 Gen10 or DL385 Gen10.
• If the label ends in -091 rather than -191, you need the Intel platform spare instead.
