HPE 16GB 1Rx4 DDR4-2666 Registered SmartMemory Kit

The HPE 815098-B21 is a 16GB SmartMemory kit from the DDR4-2666 generation. It is a registered ECC DIMM with a single rank of x4 chips and a CAS latency of 19.

The spare number 850880-001 is listed as an alternative part number. HPE assigns spare numbers to parts used in service, and they appear on failed-part labels and in repair documents, so it helps to know it when you are matching a module you have pulled from a server.

This kit is typically bought to replace a failed DIMM in a ProLiant server from that generation, or to add capacity while keeping the memory uniform. A single-rank 16GB module also leaves headroom under a server's rank limits per channel.

Confirm your server's memory guide before ordering, and keep the type and speed of every module consistent.

Available in all three conditions. New and refurbished carry a choice of 1 year or 3 years of warranty, and used carries 90 days. Add 815098-B21 to an RFQ if you are replacing a failed module and tell us its label.
