HP Z4 G4 Workstation for Professional Workflows

The HP Z4 G4 mid-tower workstation targets professionals who need reliable single-processor performance for compute-intensive applications. It ships new with Windows 11 Pro, an Intel Xeon W-2223 processor, and certified NVIDIA Quadro graphics. The configuration suits engineering, design, and data-analysis workloads requiring ISV-certified stability.

Suits ECC Memory and Certified GPU Needs.

This system suits buyers who require 64GB of DDR4 2666 ECC registered memory and a Quadro RTX 4000 8GB GDDR6 card for professional 3D CAD, rendering, or visualisation. It is not for buyers who need multi-processor scaling beyond a single Xeon W CPU, or those requiring more than 500GB of boot NVMe storage without adding drives.

LGA 2066 Socket Defines Processor Compatibility

The motherboard uses an LGA 2066 socket paired with the Intel Xeon W-2223 3.6GHz (3.9GHz Turbo) 4-core processor. This socket determines which Xeon W-series processors can be installed for future upgrades. Buyers planning CPU changes must select processors compatible with this specific socket and chipset platform.

Questions about this item

How do I install the 64GB DDR4 2666 ECC registered memory modules in the four DIMM slots, and which step is commonly missed?

Populate the four slots with the supplied 16GB sticks, ensuring each module clicks fully into its latch; the step often missed is verifying the BIOS recognises all 64GB at 2666MHz before closing the chassis.

What maintenance will the 1000W 80 Plus Gold power supply need over time?

Periodically vacuum dust from the PSU intake and exhaust vents to maintain 90% efficiency; the unit has no user-serviceable parts, so replacement is only required if it fails.

What thermal limit appears first when the Xeon W-2223 runs at 3.9GHz Turbo under sustained load?

The CPU will hit its factory turbo power ceiling and throttle from 3.9GHz to 3.6GHz base clock once the cooler saturates, limiting sustained single-thread performance.
