HP Z4 G4 Xeon W-2235 Workstation

The HP Z4 G4 is a mid-tower workstation built around a six-core Intel Xeon W-2235 processor running at 3.8GHz with a 4.6GHz turbo frequency. It ships with 256GB of DDR4 2933 ECC registered memory and a 2TB PCIe NVMe solid-state drive. An Nvidia Quadro P4000 graphics card with 8GB GDDR5 memory drives four DisplayPort 1.4 outputs. The system includes a 1000W 80 Plus Gold power supply and Windows 11 Pro.

Suits ECC memory workflows, not gaming builds

Engineers and analysts running ISV-certified CAD, simulation or rendering applications will benefit from the Xeon platform stability and large ECC memory capacity. The Quadro P4000 is certified for professional 3D workflows and multi-display setups. Buyers who need consumer gaming features, higher single-thread clock speeds or a smaller chassis should consider alternative configurations.

256GB DDR4 2933 ECC capacity

The workstation arrives with eight 32GB modules filling half the 512GB maximum supported memory. This configuration suits large datasets and complex assemblies without immediate upgrades. If your workload demands the full 512GB limit, additional modules are required. The eight populated slots leave no free DIMM positions for simple expansion.

Questions about this item

What comes in the box and do I need to buy a monitor separately?

The workstation ships with Windows 11 Pro installed, an integrated Gigabit Ethernet adapter, high-definition audio and a 1000W 80 Plus Gold power supply. A monitor is not included and must be purchased separately.

Should I choose the 256 GB DDR4 2933 configuration or add more memory later?

The system arrives with 256 GB as eight 32 GB ECC registered DDR4 2933 modules. The board supports up to 512 GB, so you can expand later if workloads grow beyond the current capacity.

How does the Xeon W-2235 3.8 GHz with 4.6 GHz turbo perform in a real build?

The six-core processor runs at a 3.8 GHz base clock and can boost to 4.6 GHz, delivering strong single-thread speed for CAD and simulation tasks while the 2 TB NVMe SSD keeps project loading fast.
