Professional workstation for compute-intensive

The HP Z4 G4 workstation combines an Intel Xeon W-2223 3.6GHz processor with 32GB DDR4 2666 ECC memory and a 4TB NVMe SSD. An Nvidia Quadro RTX 5000 16GB GPU provides certified graphics performance for 3D CAD, rendering and GPU-accelerated applications. Windows 11 Pro is pre-installed for immediate deployment.

Tool-less chassis simplifies internal access

The mid-tower design offers toolless entry to components, making memory expansion to 512GB DDR42933 straightforward. Four populated DIMM slots mean adding capacity requires replacing existing modules rather than filling empty bays. The 1000W 80 Plus Gold power supply delivers 90% efficiency to support the installed GPU and storage configuration.

PCIe NVMe and DisplayPort 1.4 define current I/O

The 4TB boot drive uses the PCIe NVMe interface for fast system responsiveness. Graphics output relies on four DisplayPort 1.4 connectors plus VirtualLink, limiting display connections to those standards. Maximum memory reaches 512GB on Xeon configurations, and the LGA 2066 socket bounds processor upgrades to compatible Xeon W or Core X-series CPUs.

Questions about this item

How can I verify the Xeon W-2223 is hitting its 3.9 GHz turbo after setup?

Open Windows Task Manager Performance tab and watch the CPU frequency under load; it should reach 3.9 GHz on active cores when thermal headroom allows.

What comes in the box and what must I buy separately to start working?

The mid-tower chassis includes the Xeon W-2223, 32 GB DDR4-2666 ECC (4×8 GB), 4 TB PCIe NVMe SSD, Quadro RTX 5000 16 GB GDDR6 with four DisplayPort 1.4 and VirtualLink, 1000 W 80 Plus Gold PSU and Windows 11 Pro; you must supply your own monitor, keyboard and mouse.

Which memory configuration should I choose if I need more capacity later?

The board supports up to 512 GB DDR4-2933 ECC; populate the remaining DIMM slots with matching 2666 MHz registered modules to expand without replacing the factory 32 GB kit.
