HP Z4 G4 Workstation with Xeon W-2235

This HP Z4 G4 mid-tower workstation is built for professionals running compute-intensive applications such as 3D CAD, rendering and large-dataset analysis. It ships new with Windows 11 Pro, an Intel Xeon W-2235 6-core processor running at 3.8GHz with a 4.6GHz turbo frequency, and 128GB of DDR4 2933 ECC registered memory. The Nvidia Quadro RTX 4000 8GB GDDR6 graphics card provides certified driver support for professional visualisation workloads.

Verify LGA 2066 motherboard clearance

Before ordering, confirm your environment can accommodate a mid-tower chassis with toolless internal access for drive and card installation. The system requires an LGA 2066 socket platform and includes a 1000W 80 Plus Gold power supply rated at 90% efficiency. Ensure available PCIe slots match the Quadro RTX 4000 256-bit interface and that your display connectors support DP 1.4 or USB-C for the GPU outputs. Maximum memory capacity is 512GB across the platform.

1000W Gold supply manages thermals for sustained

The integrated 1000W 80 Plus Gold power supply delivers stable power to the Xeon processor and Quadro RTX 4000 under continuous professional workloads. ECC registered DDR4 memory helps maintain data integrity during long compute sessions. The mid-tower design provides airflow paths for the CPU and GPU coolers while the 500GB NVMe SSD ensures fast system responsiveness without adding mechanical heat. Fan noise scales with thermal demand from rendering or simulation tasks.

Questions about this item

What is included with the HP Z4 G4 and do I need to buy a monitor separately?

The workstation ships with the Intel Xeon W-2235 processor, 128GB DDR4 2933MHz ECC memory in four 32GB modules, a 500GB M.2 NVMe SSD and an Nvidia Quadro RTX 4000 8GB GDDR6 graphics card with three DisplayPort 1.4 outputs and one USB-C port. Windows 11 Pro is pre-installed. A monitor is not included.

Should I choose the 128GB DDR4 2933MHz configuration or add more memory later?

The system arrives with 128GB (4x 32GB) DDR4 2933MHz ECC registered memory installed. The motherboard supports up to 512GB total, so you can add further modules if your workloads demand more capacity.

What does the Xeon W-2235 3.8GHz base clock with 4.6GHz turbo mean for real-world performance?

The six-core Xeon W-2235 runs at 3.8GHz base frequency and can boost to 4.6GHz on active cores, giving strong single-thread speed for CAD and simulation tasks while maintaining stability under sustained multi-core loads.
