HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2225 processor running at 4.1 GHz with a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 ECC registered memory in a four-module configuration. A 4 TB PCIe NVMe solid-state drive provides the primary storage. Graphics are handled by an Nvidia Quadro RTX 4000 card with 8 GB of GDDR6 memory on a 256-bit bus. The system includes a 1000 W 80 Plus Gold power supply and comes with Windows 11 Pro pre-installed.

Suited For Professional Visualisation Workflows

This configuration suits engineers, designers and analysts who rely on ISV-certified drivers for 3D CAD, rendering and visualisation applications. The Quadro RTX 4000 offers three DisplayPort 1.4 outputs and one USB-C connector for multi-display setups. Buyers who need more than four CPU cores for heavily threaded simulation or compilation tasks should consider other options. Workflows requiring GPU memory beyond 8 GB or consumer-grade gaming features are not addressed by this hardware.

Memory And Storage Headroom

The 32 GB DDR4 2933 ECC kit handles typical professional datasets and moderate simulation workloads comfortably. The platform supports a maximum of 512 GB of memory, leaving significant headroom for future expansion. The 4 TB NVMe drive accommodates large project libraries and active working sets with fast access speeds. When active memory demands exceed the installed 32 GB or when project archives surpass the 4 TB capacity, additional modules or drives will be required.

Questions about this item

Does the HP Z4 G4 come with a monitor, or must I supply my own display?

The workstation ships without a monitor; you will need to provide your own display and connect it to the Quadro RTX 4000, which offers three DisplayPort 1.4 outputs and one USB-C graphics port.

Can I keep my existing SATA hard drives and use them alongside the 4 TB NVMe boot drive?

Yes, the Z4 G4 chassis includes internal bays and supports SATA drives in addition to the factory-installed 4 TB PCIe NVMe SSD, so older storage can be added without removing the primary drive.

How can I verify that the 32 GB of DDR4 2933 ECC memory is running at the correct speed after setup?

Open Task Manager, select the Performance tab, choose Memory and confirm the speed reads 2933 MHz; you can also check the same value in the system BIOS or with a utility such as CPU-Z.
