HP Z4 G4 Business Desktop Xeon W-2225 4.1GHz 128GB DDR4 2TB NVMe Quadro RTX 4000 8GB Windows 11 Pro

Professional Workstation for Demanding Workflows

The HP Z4 G4 is a new mid-tower workstation built around an Intel Xeon W-2225 processor running at 4.1GHz with a 4.6GHz turbo frequency across four cores. It ships with 128GB of DDR4 2933 ECC registered memory configured as four 32GB modules. A 2TB PCIe NVMe SSD provides primary storage. An NVIDIA Quadro RTX 4000 graphics card with 8GB GDDR6 memory drives professional visualisation workloads. Windows 11 Pro is pre-installed and digitally activated.

Compatibility and Expansion Checks

Verify that your workflow benefits from ECC registered DDR4 memory and the LGA 2066 socket platform before ordering. The system supports a maximum of 512GB of DDR4 2933 memory across its available slots. The Quadro RTX 4000 provides three DisplayPort 1.4 outputs and one USB-C connector for display connectivity. Internal expansion relies on standard PCIe slots and M.2 interfaces for additional NVMe or SATA drives. Integrated Gigabit Ethernet and high-definition audio are provided on the motherboard.

Thermals, Noise and Power Draw

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers power to all components. The single-processor design and mid-tower chassis allow airflow across the Xeon W-2225 and Quadro RTX 4000 under sustained compute or rendering loads. Fan speeds scale with thermal demand from the CPU and GPU during professional application use. Acoustic output will vary with workload intensity but the platform is engineered for workstation-class thermal management in typical office environments.
