HP Z4 G4 Workstation Xeon W-2235 64GB 4TB NVMe Quadro P5000 16GB Win 11 Pro

Professional Workstation for Demanding Compute

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It ships with 64 GB of DDR4 2933 ECC registered memory across four modules and a 4 TB PCIe NVMe solid-state drive. An Nvidia Quadro P5000 graphics card with 16 GB GDDR5X memory and a 256-bit interface drives professional visualisation workloads. Windows 11 Pro is pre-installed on the system.

Memory and Storage Ceiling

The platform supports a maximum of 512 GB of DDR4 2933 ECC memory, limiting total capacity regardless of module density. The installed 4 TB NVMe drive occupies one M.2 slot; additional storage must use remaining SATA or PCIe interfaces inside the chassis. The Quadro P5000 provides four DisplayPort 1.4 outputs and one dual-link DVI-D connector, defining the native display connectivity ceiling. Expansion relies on the available PCIe slots and the 1000 W 80 Plus Gold power supply rated at 90 percent efficiency.

Xeon W-2235 Six-Core Processor

The single-socket LGA 2066 Xeon W-2235 delivers six cores at 3.8 GHz base clock with 4.6 GHz turbo, setting the compute ceiling for this configuration. Buyers needing higher core counts or dual-socket scaling must select a different workstation class. The 64 GB DDR4 2933 ECC kit fills four slots, so further memory upgrades require replacing existing modules. The 16 GB Quadro P5000 suits GPU-accelerated CAD and rendering but does not support newer API features absent from its architecture.
