Professional Workstation Platform

The HP Z4 G4 is a mid-tower business desktop built for compute-intensive professional applications. It ships with an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. The system includes 32 GB of DDR4 2933 ECC registered memory and a 1 TB PCIe NVMe solid-state drive. Windows 11 Pro comes pre-installed for immediate deployment.

Upgrade Path From Entry Systems

This configuration replaces older workstations limited to four cores, non-ECC memory or SATA-based storage. The jump is worth it when workloads demand error-correcting memory for data integrity and GPU acceleration for 3D CAD or rendering. The Xeon W-2235 and Quadro RTX 4000 combination removes bottlenecks found in consumer-grade desktops used for professional tasks.

Build Integration Requirements

The LGA 2066 platform supports up to 512 GB of DDR4 2933 memory across eight slots, leaving four slots free for expansion. A 1000 W 80 Plus Gold power supply delivers headroom for additional PCIe cards and storage drives. The Quadro RTX 4000 provides three DisplayPort 1.4 outputs and one USB-C connector for multi-display setups. Tool-less chassis access simplifies future hardware upgrades.

Questions about this item

What size power supply does the HP Z4 G4 need to support the Xeon W-2235 and RTX 4000?

The workstation ships with a 1000W 80 Plus Gold unit rated at 90% efficiency to handle the 6-core Xeon W-2235 and Quadro RTX 4000 8GB GDDR6 card.

How do I install additional DDR4 2933 ECC memory in the four slots?

Open the toolless side panel, align each 288-pin DDR4 2933 ECC registered module with the slot key, press firmly until the latches click, and populate all four channels for maximum bandwidth.

When should I replace the 1TB M.2 NVMe boot drive?

Monitor SMART health attributes and plan replacement once the drive reaches its rated endurance limit or if reallocated sector counts begin to rise.
