Professional Workstation Build

This HP Z4 G4 mid-tower workstation pairs an Intel Xeon W-2223 3.6GHz (3.9GHz Turbo) 4-core processor with 256GB DDR4 2666MHz ECC registered memory. It targets engineers, designers and analysts who need certified application stability and large memory capacity for complex simulations or 3D CAD projects.

Quadro Graphics and High-Efficiency Power

The bundled Nvidia Quadro P5000 16GB GDDR5X 256-bit card provides four DisplayPort 1.4 outputs and one dual-link DVI-D for multi-display visualisation workflows. A 1000W 80 Plus Gold 90% efficient power supply delivers certified headroom for the GPU and storage subsystem under sustained professional loads.

Tool-Less Access and Memory Ceiling

Tool-less chassis entry simplifies drive swaps and PCIe card upgrades, while eight occupied DIMM slots mean any future memory expansion requires replacing existing 32GB modules. The board supports up to 512GB total, so buyers planning beyond 256GB must budget for a full kit replacement rather than a simple addition.

Questions about this item

How many DDR4 2666 ECC modules are installed and can I add more later?

Eight 32 GB DDR4 2666 ECC registered modules fill the current 256 GB; the board supports up to 512 GB total.

Will the 1000 W 80 Plus Gold power supply limit the Quadro P5000 during long renders?

The 1000 W 80 Plus Gold unit provides ample headroom for the Quadro P5000 16 GB and Xeon W-2223 under sustained load.

How loud does the mid-tower get when the Xeon and Quadro run all day?

Tool-less access and a 90 % efficient 1000 W supply keep thermals controlled, so fan noise stays low during extended workloads.
