Professional workstation for demanding workflows
The HP Z4 G4 workstation uses a Xeon W-2135 processor with six cores at 3.70GHz. It ships with 128GB of DDR4 memory and a 512GB solid-state drive. Windows 11 Pro is preinstalled for immediate professional use. The system targets design, rendering, engineering and data-intensive applications.
Memory ceiling and storage layout
DDR4 memory can be expanded to 512GB across the available slots. Storage expansion uses two 3.5-inch bays and one M.2 slot for additional drives. The dedicated K4000 graphics card occupies one expansion slot. Front-panel LEDs show power, Ethernet and USB activity.
Capacity comfort zone and limits
The 128GB DDR4 configuration handles large assemblies, multi-layer timelines and heavy datasets without paging. The 512GB SSD holds the operating system, applications and active project files for daily work. Very large simulation jobs or multi-terabyte media libraries will require the extra 3.5-inch bays or the M.2 slot. The 55 kilogram chassis needs a stable bench or rack position.

Questions about this item
Should I pick the 128 GB DDR4 configuration or add more memory up to the 512 GB maximum?
The system ships with 128 GB DDR4 installed and supports up to 512 GB total; choose 128 GB for typical CAD and rendering workloads, or expand toward 512 GB if you regularly run large simulations or multi-application pipelines that exceed the factory amount.
What does the 3.70 GHz Xeon W-2135 clock speed deliver in everyday workstation tasks?
The 3.70 GHz base frequency on the 6-core Xeon W-2135 gives strong single-thread responsiveness for CAD modelling, code compilation and real-time viewport interaction, while the six cores handle parallel rendering and batch jobs without throttling under sustained loads.
How does the M.2 slot and 3.5-inch drive bays limit storage expansion?
One M.2 slot accepts a single solid-state module, and two 3.5-inch bays allow additional hard drives or SSDs; together they cap internal expansion at three drives, so plan your capacity and redundancy within those three positions.
