Professional CAD Workstation

The HP Z4 G4 Tower is configured for engineering, drafting, 3D modeling and technical design applications. An Intel Xeon W-2135 processor running at 3.70GHz with 48GB of installed memory handles demanding professional workloads and efficient multitasking. The NVIDIA Quadro P2000 graphics card supports workstation-class visualization tasks. Windows 11 Pro provides a business-ready operating environment.

Thermals and Power

A 750W power supply supports the installed components and allows for future add-in cards or storage upgrades. The workstation platform features a quiet and efficient cooling design intended for reliable operation under sustained professional loads. The tower form factor promotes airflow to manage thermals during extended engineering or rendering sessions.

Build and Expansion

The toolless chassis design allows easy access for memory, graphics or storage upgrades without requiring tools. Eight total memory slots support a maximum of 512GB for future expansion beyond the current 48GB configuration. The LGA 2066 socket underpins the single-processor workstation platform. Included storage combines a 512GB M.2 SSD with a 2TB HDD for responsive performance and high-capacity project storage.

Questions about this item

How do I install an M.2 SSD into the HP Z4 G4 workstation, and what step is often missed?

Insert the M.2 SSD into the motherboard slot and secure it with the retention screw; the step often missed is tightening that screw fully.

What maintenance or replacement will the 2TB HDD need later?

The 2TB HDD is a mechanical drive that will eventually require replacement due to wear; monitor SMART health and keep backups current.

What limit appears first on the Quadro P2000 during sustained heavy rendering?

The Quadro P2000 5GB VRAM fills first during sustained heavy rendering, causing texture swapping to system memory and reduced frame rates.
