Professional Xeon Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2225 processor running at 4.1 GHz with a 4.6 GHz turbo boost. It ships with 128 GB of DDR4 2933 ECC registered memory in a four-by-32 GB configuration and a 2 TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 with 8 GB of GDDR5 memory and four DisplayPort 1.4 outputs handles professional visualisation tasks. Windows 11 Pro is pre-installed.

Sustained Load Behaviour

A 1000 W 80 Plus Gold power supply rated at 90 % efficiency delivers stable power during extended compute-intensive sessions. The Xeon W-2225 maintains its turbo frequency within the thermal limits of the mid-tower chassis while the Quadro P4000 supports GPU-accelerated workloads such as 3D CAD and rendering. ISV certification confirms reliable operation with leading professional applications over long periods. ECC memory protects data integrity throughout continuous operation.

Pre-Order Checks

Verify that your workflow benefits from the four-core Xeon architecture and 128 GB memory ceiling before committing. Confirm the four DisplayPort 1.4 connectors match your display inputs, as no monitor is included. The motherboard supports up to 512 GB of DDR4 2933 ECC memory across additional slots if future expansion is planned. Ensure the mid-tower form factor fits your allocated workspace and that integrated gigabit Ethernet meets your network infrastructure requirements.

Questions about this item

How much power does the 1000W 80 Plus Gold supply draw when the Xeon W-2225 and Quadro P4000 run at full load all day?

The workstation ships with a 1000W 80 Plus Gold 90% efficient power supply designed to sustain the Xeon W-2225 4.1GHz base and 4.6GHz turbo alongside the Quadro P4000 8GB GDDR5 without thermal throttling.

Which display connectors must my monitors provide to use the Quadro P4000 8GB graphics card?

The Quadro P4000 8GB GDDR5 card provides four DisplayPort 1.4 outputs, so each monitor needs a DisplayPort 1.4 input or an active adapter.

Will my existing DDR4 2933 ECC registered modules work alongside the four 32GB sticks already installed?

The system includes 128GB as 4x 32GB DDR4 2933MHz ECC registered modules; the board supports up to 512GB total, so additional DDR4 2933 ECC registered DIMMs can be added to the remaining slots.
