HP Z4 G4 Workstation — Xeon W-2225

The HP Z4 G4 mid-tower workstation is built for professionals who need reliable single-processor performance. It ships with an Intel Xeon W-2225 four-core processor running at 4.1 GHz with a 4.6 GHz turbo frequency. The system includes 16 GB of DDR4 2933 ECC registered memory in a dual-channel configuration. A 1 TB PCIe NVMe M.2 SSD provides fast storage for the operating system and active projects.

Professional graphics and ISV certification

The NVIDIA Quadro P2000 with 5 GB GDDR5 memory on a 160-bit bus drives up to four DisplayPort 1.4 monitors. This card carries ISV certifications for major CAD, rendering and visualisation applications. Buyers who need GPU compute for deep-learning training or real-time ray tracing should consider workstations equipped with higher-tier professional graphics cards.

1000 W 80 Plus Gold power supply

A 1000 W 80 Plus Gold unit rated at 90 % efficiency delivers ample headroom for the installed Quadro P2000 and future storage or add-in cards. The LGA 2066 platform supports memory upgrades up to 512 GB of DDR4 2933 ECC RDIMMs. Verify that any planned expansion cards fit within the mid-tower chassis and the available PCIe slot layout.

Questions about this item

How do I install the 16GB DDR4 2933 memory modules into the eight DIMM slots of the Z4 G4?

Open the tool-less chassis, align each module's notch with the slot key, press firmly until the ejector clips lock, and populate the Xeon-validated channels first as shown on the motherboard diagram.

Which components will need replacement first under continuous professional workloads?

The 1000W 80 Plus Gold power supply and system fans are the primary wear items; the 1TB NVMe SSD has a finite write endurance rating that will eventually require drive replacement.

What thermal limit appears first when the Xeon W-2225 sustains 4.6GHz turbo across all four cores?

The CPU package power limit throttles clocks before the 1000W PSU or chassis airflow become constraints, reducing frequency to stay within the processor's thermal design envelope.
