HP Z4 G4 Workstation

The HP Z4 G4 is a mid-tower workstation built for professionals who need reliable single-processor performance with large memory capacity. It ships with an Intel Xeon W-2223 3.6GHz processor reaching 3.9GHz turbo, 128GB of DDR4 2666 ECC registered memory, a 1TB NVMe SSD and an Nvidia Quadro P5000 16GB graphics card. Windows 11 Pro is pre-installed for immediate deployment. This system suits engineers and designers running certified ISV applications but not buyers who need dual-processor scaling.

Thermals Noise Power

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable power to the 4-core Xeon and the Quadro P5000 under sustained loads. The mid-tower chassis uses tool-less access and directed airflow to manage thermals during 3D CAD, rendering and GPU-accelerated workloads. Integrated Gigabit Ethernet and high-definition audio add no extra cooling burden. Builders who need liquid-cooling loops or silent-studio acoustics should verify case clearance and fan curves before purchase.

Accessories Software Impact

Four DisplayPort 1.4 outputs and one dual-link DVI-D on the Quadro P5000 drive multiple high-resolution displays without adapters. The 256-bit GDDR5X frame buffer and ISV certification accelerate viewport performance in certified professional applications. Four populated DIMM slots leave four free for expansion up to the 512GB platform maximum using DDR4 modules. Additional M.2 and SATA bays allow storage growth without sacrificing the boot NVMe drive.

Questions about this item

How do I install additional DDR4 2666 ECC registered modules into the four memory slots?

Power off the workstation, remove the side panel, release the retention clips on each DDR4 slot, align the notch on the module with the key in the socket, press firmly until the clips snap closed, then replace the panel and power on.

When will the 1000W 80 Plus Gold power supply need replacement?

The 1000W Gold-rated supply is rated for continuous operation; plan to replace it after five to seven years of heavy daily use or if voltages drift outside specification.

At what temperature does the Xeon W-2223 begin to throttle under sustained load?

The Xeon W-2223 reduces its 3.9 GHz turbo frequency when the core temperature reaches 100 °C, so sustained workloads will hit that thermal limit first.
