Workstation for Demanding Professional Workflows

The HP Z4 G4 mid-tower delivers single-processor performance built for compute-intensive applications. An Intel Xeon W-2223 processor with four cores running at 3.6 GHz and a 3.9 GHz turbo frequency drives the system. It is equipped with 256 GB of DDR4 2666 ECC registered memory and a 4 TB PCIe NVMe solid-state drive. An Nvidia Quadro RTX 4000 graphics card with 8 GB GDDR6 memory provides certified visualisation capability. A 1000 W 80 Plus Gold power supply supports the configuration.

Suited for CAD, Rendering and Simulation Users

This workstation suits engineers, designers and analysts who require ISV-certified stability for 3D CAD, rendering and GPU-accelerated workloads. The four-core Xeon processor handles lightly threaded tasks at high clock speeds. Buyers who need higher core counts for parallel simulations or multi-threaded compilation should consider other configurations. The single-processor design also limits maximum memory expansion compared to dual-socket platforms.

256 GB DDR4 2666 ECC Registered Memory Installed

The system ships with 256 GB of DDR4 2666 ECC registered memory populated across eight 32 GB modules. This capacity supports large datasets and complex scenes immediately. The platform supports up to 512 GB of DDR4 2933 ECC memory on Xeon configurations, leaving headroom for future upgrades. Verify that any additional modules match the registered ECC specification for compatibility.

Questions about this item

Does the 256GB DDR4 2666 memory come pre-installed as eight 32GB modules, or must I purchase additional sticks?

The 256GB DDR4 2666 ECC Registered memory is factory-installed as eight 32GB modules, so no extra memory purchase is required to reach the listed capacity.

Should I choose the 4TB NVMe SSD or add a SATA drive for extra project storage?

The 4TB M.2 NVMe SSD is already installed for fast system responsiveness; additional SATA drives can be added later using the internal storage bays if more capacity is needed.

Will the Quadro RTX 4000 8GB GDDR6 with three DP 1.4 ports and one USB-C drive my 4K displays at full refresh?

The Quadro RTX 4000 provides three DisplayPort 1.4 outputs and one USB-C graphics connector, supporting multiple 4K displays at their native refresh rates for professional visualisation workloads.
