HP Z4 G4 Business Desktop Xeon W-2235 3.8GHz 16GB 500GB NVMe Quadro P2000 5GB

HP Z4 G4 Xeon W-2235 Workstation

This mid-tower business desktop targets professionals who need certified reliability for 3D CAD, rendering and GPU-accelerated workloads. It ships with Windows 11 Pro, an Intel Xeon W-2235 six-core processor running at 3.8 GHz with 4.6 GHz turbo, 16 GB of DDR4 2933 ECC registered memory and a 500 GB NVMe SSD. The NVIDIA Quadro P2000 provides 5 GB GDDR5 on a 160-bit bus with four DisplayPort 1.4 outputs.

Installation and common issues

The chassis uses toolless access for memory, storage and graphics upgrades, and the 1000 W 80 Plus Gold power supply delivers ample headroom for supported add-in cards. Builders must populate DDR4 2933 ECC registered modules only; non-ECC or faster DDR4 generations will not function. The LGA 2066 socket limits CPU changes to compatible Xeon W or Core X-series parts, and the single-processor board does not support dual-socket configurations.

Sustained-load behaviour

The 1000 W Gold-rated supply maintains 90 % efficiency during extended render or simulation runs, keeping voltage rails stable for the Xeon and Quadro. DDR4 2933 ECC memory corrects single-bit errors on the fly, preventing silent data corruption in large datasets. The Quadro P2000 5 GB frame buffer handles prolonged GPU compute and multi-display output without throttling, while the integrated gigabit Ethernet and high-definition audio remain active throughout.
