Built for professional compute

This HP Z4 G4 mid-tower workstation pairs a 4-core Intel Xeon W-2225 running at 4.1GHz with 4.6GHz Turbo and an Nvidia Quadro RTX 4000 8GB GDDR6 graphics adapter. It ships with 16GB of DDR4 2933 ECC registered memory in a dual-channel 2x8GB configuration and a 4TB PCIe NVMe SSD. Windows 11 Pro 64-bit is pre-installed and digitally activated for immediate deployment in CAD, rendering or simulation workflows.

Check memory slots and display connections

The motherboard uses LGA 2066 sockets and supports up to 512GB of DDR4 ECC SDRAM across its DIMM slots; verify how many slots remain free before adding capacity. The Quadro RTX 4000 provides three DisplayPort 1.4 outputs and one USB-C connector for display connectivity, so confirm your monitors match these interfaces. Internal storage bays and M.2 slots allow further SATA or NVMe expansion if project storage needs grow beyond the factory 4TB drive.

1000W Gold supply handles sustained loads

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable power to the CPU and GPU during extended compute or rendering sessions. The mid-tower chassis uses tool-less access for straightforward maintenance and component upgrades. Integrated Gigabit Ethernet and high-definition audio are provided on the motherboard for standard wired networking and sound output without add-in cards.

Questions about this item

What comes in the box and is a monitor included?

The workstation ships with the HP Z4 G4 tower, an Intel Xeon W-2225 processor, 16GB DDR4 2933 ECC memory, a 4TB M.2 NVMe SSD, an Nvidia Quadro RTX 4000 8GB graphics card, a 1000W 80 Plus Gold power supply, and Windows 11 Pro. No monitor is included.

Should I choose the 16GB DDR4 2933 configuration or add more memory later?

The system includes 16GB as 2x 8GB DDR4 2933 ECC Registered modules. It supports up to 512GB total, so you can start with the factory configuration and add compatible ECC Registered DDR4 2933 modules later if workloads demand it.

What does the Xeon W-2225 4.1GHz figure mean for actual performance?

The Xeon W-2225 runs at a 4.1GHz base clock and can boost to 4.6GHz Turbo across its 4 cores, delivering high single-thread speed for CAD and simulation tasks while the 16GB ECC memory and Quadro RTX 4000 handle large datasets and GPU-accelerated rendering.
