HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower business desktop built for professional workloads. It ships new with Windows 11 Pro and an Intel Xeon W-2225 processor. The system includes 128GB of DDR4 2933 ECC registered memory and a 500GB NVMe SSD. An Nvidia Quadro P2000 5GB graphics card provides certified driver support.

Suits ISV-certified workflows, not gaming

This workstation suits engineers and designers running certified CAD, rendering or simulation applications. The Xeon platform delivers ECC memory reliability and ISV-tested stability for critical projects. Buyers who want higher single-thread speeds for gaming or general office tasks should look at something else. The Quadro P2000 targets professional viewports, not high frame-rate entertainment.

128GB DDR4 2933 ECC memory capacity

The single specification that decides fit is the 128GB DDR4 2933 ECC registered memory configuration. Four 32GB modules fill four slots and provide error-correcting reliability for large datasets. The platform supports up to 512GB maximum, so this build leaves room for expansion. Confirm your application requires ECC registered DDR4 before purchasing.

Questions about this item

Should I pick the 128GB DDR4 2933 ECC configuration or add more later?

The workstation ships with 128GB as four 32GB DDR4 2933 ECC registered modules; the platform supports up to 512GB, so you can expand later if workloads grow.

What does the Xeon W-2225 4.1GHz 4.6GHz Turbo 4 Core mean for daily CAD renders?

The four cores run at 4.1GHz base and boost to 4.6GHz, giving strong single-thread speed for interactive viewport work while the 128GB ECC memory keeps large assemblies stable.

Does the Quadro P2000 5GB GDDR5 160-bit with DP 1.4 drive 4K monitors at 60Hz?

Yes, the card provides four DisplayPort 1.4 outputs; each can drive a 4K 60Hz display, and the 5GB GDDR5 frame buffer handles typical professional 3D models.
