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.

Questions about this item
How does the 2133 MT/s speed translate to actual bandwidth inside a server?
The module runs at DDR4-2133, delivering up to 17000 MB/s theoretical peak bandwidth per channel when installed in a compatible platform.
What does the PC4-17000 rating limit in a live system?
PC4-17000 caps the data rate at 2133 MT/s, so the memory controller cannot push this DIMM beyond that speed even if the platform supports faster DDR4.
Will the LRDIMM form factor fit in a standard 288-pin DDR4 slot?
Yes, it uses the standard 288-pin DDR4 LRDIMM layout, so it seats in any server board slot wired for load-reduced DDR4 modules.
