850880-001 is the HPE spare part number for 16GB (1x16GB) Single Rank x4 DDR4-2666 CAS-19-19-19 Registered Smart Memory Kit. This is the number HPE service documentation, iLO event logs, and the module's own label use to identify a failed DIMM in the field. The module is a 288-pin DDR4 registered DIMM with ECC, single rank, x4 chip organization, running at 2666 MHz to PC4-21300 at 1.2 V with CL19 timings of 19-19-19. It is supported in Gen10 servers with first-generation processors, including DL360, DL380, DL560, DL580, BL460c, ML110, ML350, XL170r, and XL190r. Replace the failed DIMM in the same slot to preserve the existing population rules.

FREQUENTLY ASKED QUESTIONS ABOUT 850880-001
What is the difference between 850880-001 and 815098-B21?
They are the same physical memory module under two different HPE numbering schemes. 850880-001, the number on this page, is the spare part number, used in service documentation and printed on the module itself for replacement identification. 815098-B21 is the option kit number, used when the memory is ordered as a configurable or add-on purchase. This family also has one assembly revision, listed in the cross-reference block on this page. An assembly part number identifies a manufacturing-level build revision of the same module.
Will this module work alongside the DIMMs already installed in my server?
It matches the electrical and timing profile of the original: 16 GB, single rank, x4 organization, DDR4-2666
