HP Z4 G4 Workstation Xeon W-2225

This new HP Z4 G4 mid-tower workstation is built for professionals running compute-intensive applications such as 3D CAD, rendering and large-dataset simulations. It pairs a 4-core Intel Xeon W-2225 processor with 32GB of DDR4 2933 ECC registered memory and an Nvidia Quadro RTX 5000 16GB GDDR6 graphics adapter. Windows 11 Pro is pre-installed and activated. The system suits engineers and designers who need certified ISV reliability and professional graphics support.

Thermals Noise Power

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable power to the CPU, GPU and storage subsystem. The Xeon W-2225 operates at a 4.1GHz base frequency with a 4.6GHz turbo boost, while the Quadro RTX 5000 draws power through the board and auxiliary connectors. The mid-tower chassis uses directed airflow paths to manage thermal load during sustained workloads. Integrated Gigabit Ethernet and high-definition audio add minimal extra heat.

Build Connectors Mounting

The chassis provides toolless access to internal components and multiple PCIe slots for expansion cards. Storage flexibility includes M.2 slots for PCIe NVMe drives and bays for SATA devices, with a 1TB M.2 NVMe SSD already installed. The Quadro RTX 5000 offers four DisplayPort 1.4 outputs and a VirtualLink connector for high-resolution displays. An LGA 2066 socket and four populated DIMM slots leave room to reach the 512GB maximum memory capacity. No monitor is included.

Questions about this item

How do I install the Quadro RTX 5000 16GB GDDR6 graphics card and what step is often missed?

The Quadro RTX 5000 16GB GDDR6 installs into a PCIe slot with toolless access; the step often missed is connecting the required auxiliary power cables from the 1000W 80 Plus Gold supply before closing the chassis.

What maintenance or replacement will the 32GB DDR4 2933MHz ECC Registered memory need later?

The 32GB DDR4 2933MHz ECC Registered memory uses four 8GB modules; if capacity must grow, replace modules with higher-density DDR4 2933 ECC Registered DIMMs up to the 512GB maximum supported.

What limit appears first when the Xeon W-2225 4.1GHz (4.6GHz Turbo) 4-core processor runs sustained heavy workloads?

The Xeon W-2225 4.1GHz (4.6GHz Turbo) 4-core processor will hit its thermal and power envelope first during sustained heavy workloads, causing clock speeds to drop from the 4.6GHz turbo toward the 4.1GHz base.
