Frequently Asked Questions

Is 819415-001 interchangeable with 809208-B21 and 809086-091?

Yes — all three are HPE 128GB DDR4-2400 8Rx4 ECC LRDIMM modules with identical specifications for ProLiant Gen9. 819415-001 is the spare part, 809208-B21 is the option kit, and 809086-091 is the factory/OEM variant — all are functionally interchangeable.

Where can I find the HPE spare part number on installed memory modules?

The HPE spare part number is printed on the DIMM label alongside the option part number. In some cases it can also be retrieved via HPE iLO (Integrated Lights-Out) memory inventory reports.

How many 819415-001 modules can be installed in a DL580 Gen9?

The DL580 Gen9 supports up to 96 DIMM slots across 4 processor sockets. At 128GB per slot with 819415-001, theoretical maximum capacity is 12TB. Consult HPE ProLiant DL580 Gen9 QuickSpecs for validated LRDIMM population rules.

The HPE 819415-001 128GB DDR4-2400 LRDIMM spare delivers maximum-density field-replacement memory for HPE ProLiant Gen9 platforms. Order today — in stock at the best price.
