HP Z4 G4 Mid-Tower Workstation Xeon W-2225 16GB 2TB NVMe Quadro P4000 8GB Windows 11 Pro

Z4 G4 Xeon W-2225 Workstation

The HP Z4 G4 mid-tower workstation ships new with an Intel Xeon W-2225 four-core processor running at 4.1 GHz base and 4.6 GHz turbo. It includes 16 GB of DDR4 2933 ECC registered memory in a two-by-eight configuration. A 2 TB PCIe NVMe solid-state drive provides the primary storage volume. The Nvidia Quadro P4000 graphics card adds 8 GB of GDDR5 memory and four DisplayPort 1.4 outputs. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Upgrade From Older Z-Series Or Entry Workstations

This system replaces ageing single-socket towers that max out below 512 GB of memory or lack certified professional graphics. The jump is worth it when your workloads need ECC memory stability, ISV-certified drivers, and a 1000 W 80 Plus Gold power supply that sustains high turbo clocks. Builders staying with consumer platforms or non-ECC memory will not gain the reliability this configuration delivers.

Build Integration: Slots, Power And Expansion

The LGA 2066 motherboard exposes multiple PCIe slots for add-in cards and additional M.2 or SATA drives. Tool-less chassis access simplifies installing the 512 GB maximum DDR4 capacity or extra storage bays. Integrated gigabit Ethernet and high-definition audio handle baseline connectivity. The Quadro P4000 occupies one full-height slot and drives up to four displays, leaving remaining slots free for capture cards, fibre-channel adapters or additional GPUs.
