Professional Workstation for Demanding Workflows

The HP Z4 G4 mid-tower workstation targets professionals who need reliable single-processor performance. It runs an Intel Xeon W-2225 four-core processor at 4.1 GHz with a 4.6 GHz turbo frequency. The system includes 256 GB of DDR4 2933 ECC registered memory across eight 32 GB modules. A 2 TB PCIe NVMe solid-state drive provides primary storage. Windows 11 Pro comes pre-installed for immediate deployment.

Quadro P4000 Graphics and 1000W Gold Power Supply

The Nvidia Quadro P4000 8 GB GDDR5 graphics card delivers certified professional visualisation through four DisplayPort 1.4 outputs. An integrated 1000 W 80 Plus Gold power supply rated at 90 % efficiency supports the graphics card and allows headroom for additional internal components. Tool-less chassis access simplifies future upgrades or maintenance of storage and expansion cards.

Suited for ISV-Certified CAD and Simulation Tasks

This configuration suits engineers and designers running ISV-certified applications for 3D CAD, rendering and simulation that benefit from ECC memory and professional GPU drivers. Buyers who require dual-processor scaling, more than 512 GB maximum memory capacity or a different GPU architecture should evaluate alternative platforms.

Questions about this item

Will the eight 32 GB DDR4 2933 ECC registered modules need replacing if I expand memory later?

The board supports up to 512 GB, so you can add more DDR4 2933 ECC registered sticks without removing the existing 256 GB configuration.

What limits sustained CPU performance at the 4.6 GHz turbo frequency?

The Xeon W-2225 4-core processor will hit its thermal and power envelope before the 1000 W 80 Plus Gold supply becomes a constraint.

How loud and hot does the Quadro P4000 8 GB GDDR5 run during all-day rendering?

The 1000 W 80 Plus Gold unit and mid-tower airflow keep the GPU and CPU within spec, though fan speed rises noticeably under continuous load.
