HP Z2 G4 Mid-Tower Workstation

The HP Z2 G4 Mid-Tower Workstation is a new business desktop powered by an Intel Core i9-9900K processor with eight cores running at 3.6 GHz and a 5.0 GHz turbo frequency. It ships with 32 GB of DDR4 2666 MHz memory and a 4 TB PCIe NVMe solid-state drive. Windows 11 Pro 64-bit is pre-installed and digitally activated. Integrated Intel UHD Graphics 630 provides dual DisplayPort video output.

Suited for professional workloads needing high

This workstation suits professionals who need strong single-thread performance for CAD, simulation or compile tasks and want a quiet mid-tower form factor. The 4 TB NVMe drive gives fast local storage for active projects. Buyers who need discrete professional graphics cards for GPU-accelerated rendering or compute should look at a different configuration, as this unit relies on integrated graphics only.

4 TB PCIe NVMe SSD decides fit

The single specification that decides whether this is the right part is the 4 TB PCIe NVMe solid-state drive. It determines both the total capacity available for the operating system, applications and active data and the interface speed for that storage. Confirm that your workflow fits within this single volume before purchase.

Questions about this item

How can I verify the Intel Core i9-9900K is hitting its 5.0GHz turbo speed after setting up the workstation?

Open Task Manager in Windows 11 Pro, select the Performance tab, and watch the CPU frequency climb to 5.0GHz when a heavy single-threaded load runs.

What ships inside the mid-tower case and which essential item is not included?

The box contains the Z2 G4 chassis with the i9-9900K, 32GB of DDR4 2666 memory in four 8GB modules, a 4TB NVMe SSD, integrated Intel UHD Graphics 630 with dual DisplayPort outputs, a 500W 90% efficient power supply and Windows 11 Pro digitally activated; a monitor is not included.

Should I choose the 32GB DDR4 2666 configuration or plan to expand toward the 128GB maximum later?

The system arrives with four 8GB DDR4 2666 sticks filling all slots; keeping the 32GB setup avoids the cost and effort of replacing modules if you later decide to reach the 128GB ceiling.
