Capacity and compatibility

This 128 GB DDR4 module targets server and workstation administrators who need a single high-density stick to expand memory capacity in supported HP platforms. The part is built as a direct replacement for the HP L22096-001 specification.

Upgrade path

It replaces lower-capacity DDR4 LRDIMMs when the system’s memory controller and BIOS support 8Rx4 3DS/TSV organisation at 2666 MHz. The jump is worthwhile when workloads demand more than the current installed total and the platform qualifies this exact part number.

Installation notes

The 288-pin DIMM seats in standard DDR4 slots, but the 262-pin form-factor notation in the supplier data means installers must confirm the physical keying matches their chassis. Misalignment or mixing ranks across channels are the most common causes of a failed POST.

Questions about this item

Will this 288-pin DDR4 LRDIMM fit my server's memory slots?

The module uses the standard 288-pin DDR4 DIMM form factor; verify your platform supports DDR4 2666 LRDIMMs before installing.

What is the correct way to seat this 128GB LRDIMM, and what step do people often miss?

Align the notch with the slot key, press firmly until both side clips click, and ensure the 1.2V DDR4 voltage matches your system configuration.

When will this ECC LRDIMM need replacement or maintenance?

No scheduled maintenance is required; the module is tested for reliability and covered by a lifetime warranty for the duration of its service life.
