HP Z4 G4 Workstation Xeon W-2223 3.6GHz 16GB DDR4 500GB NVMe RTX 5000 16GB Windows 11 Pro

Z4 G4 Xeon W-2223 Workstation

This HP Z4 G4 mid-tower workstation targets professionals running compute-intensive applications such as 3D CAD, rendering and GPU-accelerated simulations. It ships with an Intel Xeon W-2223 four-core processor at 3.6GHz with 3.9GHz Turbo, 16GB DDR4 2666 ECC registered memory and a 500GB M.2 NVMe SSD. The Nvidia Quadro RTX 5000 16GB GDDR6 graphics card provides four DisplayPort 1.4 outputs plus VirtualLink. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Sustained load behaviour

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable power during extended rendering or simulation sessions. The Xeon W-2223 maintains its 3.6GHz base clock under continuous multi-threaded workloads, while the Quadro RTX 5000 16GB frame buffer handles large datasets without swapping. ECC registered memory corrects single-bit errors on the fly, preserving data integrity during long compute runs. The mid-tower chassis uses directed airflow to keep CPU and GPU temperatures controlled over hours of operation.

Installation and common issues

Tool-less side-panel access exposes four DDR4 slots, multiple PCIe slots and M.2 bays for straightforward memory, GPU or storage upgrades. The LGA 2066 socket requires careful CPU alignment if the processor is ever reseated. Builders who need more storage can add SATA or additional NVMe drives in the available bays. Buyers who want more graphics memory or a second GPU must verify chassis length clearance and power-cable routing before purchasing. Windows 11 Pro activates automatically on first internet connection.
