HP Z4 G4 Mid-Tower Workstation Xeon W-2225 4.1GHz 32GB DDR4 1TB NVMe Quadro P5000 16GB Windows 11 Pro

Professional Workstation for Compute-Intensive

The HP Z4 G4 Mid-Tower Workstation is built for professionals who need single-processor performance in demanding applications such as 3D CAD, rendering and complex simulations. It ships with Windows 11 Pro and an NVIDIA Quadro P5000 16GB graphics adapter certified for professional software. This system targets users who rely on ISV-certified reliability rather than consumer-grade components. It is not suited for buyers who need multi-processor scaling or server-class redundancy.

DDR4 2933 ECC Memory Expands to 512 GB

The platform supports up to 512 GB of DDR4 2933 ECC Registered memory across its DIMM slots, with 32 GB installed as standard. The Xeon W-2225 memory controller defines this ceiling; exceeding it is not possible on this socket. Builders who need more than half a terabyte of RAM must choose a different platform. The four included 8 GB modules occupy slots that could otherwise hold higher-capacity DIMMs for future upgrades.

LGA 2066 Socket Locks Processor Choice

The Intel Xeon W-2225 4.1 GHz (4.6 GHz Turbo) 4-core processor fits the LGA 2066 socket, which determines every compatible CPU upgrade. No other socket type fits this motherboard, so processor changes are limited to the Xeon W and Core X-series families supported by this chipset. Buyers who want a different socket or a higher core count within the same generation cannot use this chassis. The 1000W 80 Plus Gold power supply delivers headroom for supported configurations.
