Professional Workstation for Demanding Workflows

The HP Z4 G4 Mid-Tower Workstation is built for professionals who need reliable single-processor performance for compute-intensive applications. It ships with an Intel Xeon W-2235 6-core processor running at 3.8GHz with a 4.6GHz turbo frequency, 64GB of DDR4 2933MHz ECC registered memory, and a 2TB PCIe NVMe SSD for fast data access.

Thermals Noise and Power Efficiency

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable power to the CPU and Nvidia Quadro RTX 5000 16GB GDDR6 graphics card with 256-bit memory interface. The workstation chassis is engineered for professional workloads, providing cooling capacity for sustained high-frequency operation across all six cores and the GPU during extended rendering or simulation tasks.

Build Integration and Expansion

The LGA 2066 platform supports up to 512GB of DDR4 memory across available slots, while multiple PCIe slots and tool-less access simplify future upgrades. Four DisplayPort 1.4 outputs and a VirtualLink connector on the graphics card drive professional displays without adapters. Integrated Gigabit Ethernet and high-definition audio handle connectivity and sound without additional cards, leaving expansion slots free for specialised add-in boards.

Questions about this item

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

The RTX 5000 16GB arrives factory-installed in a PCIe slot with its 256-bit GDDR6 memory active; the step often missed is connecting the internal power cables from the 1000W 80 Plus Gold supply to the card before closing the mid-tower case.

What maintenance will the 2TB NVMe SSD and 64GB DDR4 2933 memory need later?

The 2TB PCIe NVMe SSD has no moving parts to service; the 64GB DDR4 2933 ECC Registered memory is seated in tool-less slots and only needs replacement if a module fails, which the system will flag at boot.

What limit appears first when the Intel Xeon W-2235 runs at 4.6GHz Turbo under sustained load?

The 1000W 80 Plus Gold power supply and mid-tower thermal design set the practical ceiling; the Xeon W-2235 will throttle from 4.6GHz Turbo toward its 3.8GHz base once the cooling capacity is saturated.
