HP 726722-B21 32GB DDR4 LRDIMM accessory

HP 32GB DDR4 LRDIMM Memory Kit

This HP 32GB memory kit uses a single LRDIMM module built for server platforms that require registered ECC memory. It suits administrators upgrading compatible HP ProLiant or Apollo systems where load-reduced DIMMs are qualified. The module is not designed for consumer desktop or laptop motherboards that accept only unbuffered non-ECC memory. Buyers who need unbuffered DIMMs or capacities beyond 32GB per slot should verify platform support first.

Quad-Rank X4 DDR4-2133 Specification

The decisive specification is the quad-rank x4 organisation running at DDR4-2133 (PC4-17000). Only systems whose memory controllers explicitly support quad-rank LRDIMMs at this data rate can use the module; platforms limited to dual-rank or single-rank registered DIMMs will not recognise the full capacity. The registered buffer and ECC function are mandatory requirements, so non-ECC or unregistered slots cannot accept this part.

OEM Module Without Retail Extras

The kit ships as a single OEM module without a retail heat-spreader, installation tool or bundled software. System integrators receive only the memory stick, relying on the server chassis airflow and existing management firmware for thermal monitoring and configuration. No diagnostic utilities or firmware update packages are included in the package.
