HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2225 processor running at 4.1 GHz with a 4.6 GHz turbo frequency across four cores. It ships with 128 GB of DDR4 2933 ECC registered memory in a four-module configuration and a 500 GB PCIe NVMe solid-state drive. Windows 11 Pro is pre-installed for professional environments.

Memory and Storage Limits

The platform supports up to 512 GB of DDR4 2933 ECC memory, allowing expansion beyond the factory 128 GB. Internal bays and M.2 slots accept combinations of SATA and PCIe NVMe drives for additional capacity. The Nvidia Quadro RTX 4000 provides 8 GB of GDDR6 memory on a 256-bit bus and offers three DisplayPort 1.4 outputs plus one USB-C graphics connector.

Power Supply and Chassis Access

A 1000 W 80 Plus Gold power supply rated at 90 percent efficiency delivers stable power for the processor, memory and professional graphics card. The mid-tower chassis is designed for tool-less access to internal components and includes multiple PCIe slots for future upgrades. Integrated Gigabit Ethernet and high-definition audio are provided on the motherboard.

Domande su questo articolo

Should I pick the 128GB DDR4 2933 kit or add more modules up to the 512GB maximum?

The system ships with 128GB as four 32GB DDR4 2933 ECC registered modules. Four slots remain free, so you can expand later to the 512GB ceiling if workloads grow.

What does the Xeon W-2225 4.1GHz base clock with 4.6GHz turbo mean for daily rendering?

The four-core Xeon W-2225 runs at 4.1GHz base and boosts to 4.6GHz under load, giving strong single-thread speed for CAD and responsive viewport performance in professional apps.

Will the Quadro RTX 4000 8GB GDDR6 256-bit drive my three DisplayPort 1.4 monitors and the USB-C display simultaneously?

The card provides three DisplayPort 1.4 outputs and one USB-C connector, all active at once, so four professional displays are supported directly from the GPU.
