HP Z4 G4 Workstation Xeon W-2225 256GB DDR4 1TB NVMe RTX 4000 8GB

Workstation for compute-heavy workflows

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2225 processor running at 4.1GHz with a 4.6GHz turbo frequency across four cores. It ships with 256GB of DDR4 2933 ECC registered memory configured as eight 32GB modules. The system targets professionals who need certified reliability for 3D CAD, rendering and GPU-accelerated applications.

PCIe Gen 3 and DDR4 2933 ceiling

The platform uses an LGA 2066 socket and supports memory up to DDR4 2933 speeds, limiting bandwidth to that standard. The Nvidia Quadro RTX 4000 connects through a PCIe slot and provides three DisplayPort 1.4 outputs plus one USB-C connector. Integrated Gigabit Ethernet and high-definition audio handle baseline connectivity without additional cards.

256GB memory with 512GB headroom

The installed 256GB DDR42933 capacity handles large datasets and complex simulations comfortably, while the motherboard supports a maximum of 512GB for future expansion. A 1TB PCIe NVMe SSD supplies fast system responsiveness and project storage. The 1000W 80 Plus Gold power supply delivers 90% efficiency to sustain the GPU and CPU under sustained professional loads.
