This HP Z4 G4 mid-tower workstation is built for engineers, designers and analysts who need certified reliability for CAD, rendering and simulation tasks. It ships new with Windows 11 Pro, an Intel Xeon W-2223 processor and professional NVIDIA Quadro RTX graphics. The configuration targets single-processor performance in a serviceable chassis.

Tool-less Access and 1000W 80 Plus Gold Power

Internal components are reachable without tools, simplifying memory, storage or graphics upgrades. The included 1000W power supply runs at 80 Plus Gold 90% efficiency, delivering stable current for the Quadro RTX 4000 and Xeon CPU. Ensure the workstation’s physical dimensions suit your workspace before installation.

Verify DDR4 ECC Registered Memory

The system uses 64GB of DDR4 2666 ECC Registered memory across four slots, expandable to 512GB; only DDR4 ECC Registered modules are supported. The processor requires an LGA 2066 socket. Confirm your display devices use DisplayPort 1.4 or USB-C, as the graphics card provides three DP 1.4 ports and one USB-C connector.

Questions about this item

How can I verify the Quadro RTX 4000 is running at full 8GB GDDR6 capacity after installing Windows 11 Pro?

Open NVIDIA Control Panel and confirm the GPU shows 8GB GDDR6 memory with three DisplayPort 1.4 and one USB-C outputs active.

What components are included and what must I purchase separately to start working?

The workstation includes the Xeon W-2223 processor, 64GB DDR4 2666 ECC memory (4x 16GB), 4TB M.2 NVMe SSD, Quadro RTX 4000 graphics, 1000W 80 Plus Gold PSU, and Windows 11 Pro. A monitor, keyboard, and mouse are not included.

Should I choose the 4TB NVMe configuration or plan to add more storage later using the internal bays?

The 4TB M.2 NVMe drive provides high-speed primary storage. Additional SATA or PCIe NVMe drives can be installed in the internal bays and M.2 slots for expanded project storage capacity.
