HPE 32GB (1 x 32GB) Dual Rank x4 DDR4-2400 CAS-17-17-17 Registered Memory Kit

819412-001 is the HPE spare part number for 32GB (1 x 32GB) Dual Rank x4 DDR4-2400 CAS-17-17-17 Registered Memory Kit. This is the number HPE service documentation, iLO event logs, and the label on the module itself use to identify a failed DIMM in the field. The module is a 288-pin DDR4 registered DIMM, dual rank, x4 organization, rated at 2400 MHz to PC4-19200 with CL17 timings of 17-17-17, ECC data integrity, and 1.2 V operation. It is supported in HPE Gen9 servers configured with v4 processors, including DL360 Gen9, DL380 Gen9, ML350 Gen9, BL460c Gen9, and XL170r Gen9.

FREQUENTLY ASKED QUESTIONS ABOUT 819412-001

What is the difference between 819412-001 and 805351-B21?

They are the same physical memory module under different HPE numbering schemes. 819412-001, the number on this page, is the spare part number: the field-replaceable identifier that appears in service documentation and on the module label. 805351-B21 is the option kit number, used when the memory is ordered as a configurable upgrade. This family also includes one assembly revision, listed in the cross-reference block on this page. An assembly part number identifies the manufactured build of the module as it leaves production.

I pulled this number from an iLO log. Will this module drop straight in?

Yes, provided the slot and server match the original configuration. The module is a 288-pin DDR4 registered DIMM with ECC, dual rank, x4 chip organization, PC4-19200 at 2400 MHz, CL17 (17-17-17), 1.2 V. Because 819412-001 is the spare number for that exact module, replacing a failed DIMM carrying this number preserves rank, organization, voltage, and timing characteristics in the existing bank.

Which servers is 819412-001 supported in?

It is supported in HPE Gen9 platforms configured with v4 processors: BL460c Gen9, DL60 Gen9, DL80 Gen9, DL120 Gen9, DL160 Gen9, DL180 Gen9, DL360 Gen9, DL380 Gen9, ML110 Gen9, ML150 Gen9, ML350 Gen9, XL170r Gen9, XL190r Gen9, and WS460c Gen9. The v4 processor qualifier matters, as the supported list is tied to that CPU generation rather than to the chassis model alone.

What arrives in the box?

A single 32 GB DDR4-2400 registered DIMM. The kit is 1 x 32GB, so one module ships per unit. If you are replacing more than one failed DIMM, or populating multiple channels, order the corresponding quantity. No riser, bracket, or additional hardware is part of this part number; it is the memory module itself as identified by the spare number 819412-001.

Can I mix this DIMM with the modules already installed?

Match the existing population where you can. This module is dual rank with x4 chip organization, registered with ECC, running at 2400 MHz to PC4-19200 with CL17 timings at 1.2 V. Populating a channel with DIMMs of differing rank, organization, or rated speed changes how the memory controller configures the bank. Replacing like for like against the failed module keeps the installed configuration consistent.
