HP Z4 G4 Workstation Xeon W-2225

This new mid-tower workstation targets professionals who need certified reliability for compute-intensive workflows. It ships with Windows 11 Pro and a 1000W 80 Plus Gold power supply. The chassis provides toolless access for simple upgrades and maintenance.

Suits single-threaded CAD and simulation users

Engineers running lightly threaded CAD, BIM or simulation tasks benefit from the 4.1 GHz base clock and 4.6 GHz turbo. Buyers who need higher core counts for rendering or virtualisation should consider other configurations. The four-core layout limits parallel throughput.

256GB DDR4 2933 ECC Registered memory

Eight 32 GB modules fill the installed capacity and leave room to reach the 512 GB maximum. The registered ECC design protects data integrity for large datasets. Verify your application's memory scaling before committing to this configuration.
