Professional Workstation for Compute-Intensive Tasks

The HP Z4 G4 mid-tower workstation targets professionals who need reliable single-processor performance for demanding workflows. It ships new with Windows 11 Pro and a 1000W 80 Plus Gold power supply rated at 90% efficiency. The system suits users running certified ISV applications such as 3D CAD, rendering, visualization and GPU-accelerated workloads.

Mid-Tower Build with Professional Graphics

The black chassis provides toolless access to internal components and multiple PCIe slots for upgrades. Integrated Gigabit Ethernet and high-definition audio handle basic connectivity. The Nvidia Quadro P5000 16GB GDDR5X 256-bit graphics adapter delivers four DisplayPort 1.4 outputs and one dual-link DVI-D connector for multi-display setups.

Xeon W-2225 4-Core Processor with 4.6GHz Turbo

The Intel Xeon W-2225 runs at 4.1GHz base frequency and reaches 4.6GHz turbo on four cores via LGA 2066 socket. Memory consists of 16GB DDR4 2933MHz ECC registered modules in a 2x 8GB configuration, expandable to 512GB maximum. A 4TB M.2 NVMe PCIe SSD provides primary storage. Buyers needing higher core counts or larger initial memory should consider other configurations.

Questions about this item

Does the Intel Xeon W-2225 processor limit the speed of the 4TB PCIe NVMe SSD?

The Xeon W-2225 connects the M.2 NVMe drive directly through its PCIe lanes, so the SSD runs at its full rated speed without a chipset bottleneck.

What internal clearance and power connectors does the Nvidia Quadro P5000 16GB require in this mid-tower chassis?

The card occupies two full-height slots and draws power from the 1000W 80 Plus Gold supply; the tool-less chassis provides enough length and width for the 256-bit GDDR5X board.

How is the 16GB DDR4 2933 ECC registered memory installed, and what slot rule do builders often miss?

The system ships with two 8GB modules in the first channel; when adding DIMMs, populate all four channels evenly to keep quad-channel bandwidth and ECC integrity.
