HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2235 3.8GHz 6-core processor that reaches 4.6GHz Turbo. It ships with 256GB DDR4 2933MHz ECC Registered memory across eight 32GB modules and a 4TB PCIe NVMe SSD. Nvidia Quadro P5000 16GB GDDR5X graphics with four DisplayPort 1.4 and one DVI-D DL outputs drive professional visualisation workloads. Windows 11 Pro is pre-installed.

Installation and Common Issues

The chassis uses toolless access for memory, storage and expansion cards, so the 8 DIMM slots and M.2 bays are reachable without a screwdriver. The 1000W 80 Plus Gold supply uses standard ATX connectors; verify cable routing clearance for full-length cards. ECC Registered DDR4 2933 modules must match the installed 32GB sticks — mixing unbuffered or different speeds will prevent boot. Quadro P5000 occupies a double-width PCIe slot and needs its auxiliary power lead seated firmly.

Pre-Purchase Checks

Confirm your workload benefits from ECC Registered DDR4 and the LGA 2066 Xeon platform; consumer Core X-series CPUs do not support ECC on this board. The 512GB maximum memory ceiling limits future expansion beyond the factory 256GB. Quadro P5000 requires DisplayPort 1.4 or DVI-D DL monitors — HDMI adapters may not carry full resolution or 10-bit colour. Ensure your software stack is certified for Quadro drivers and Windows 11 Pro.

Questions about this item

How do I verify the Xeon W-2235 is boosting to 4.6 GHz after setup?

Open Task Manager's Performance tab and watch the CPU frequency climb to 4.6 GHz under a heavy single-thread load.

What ships in the box and what must I source separately?

The mid-tower chassis, 1000 W 80 Plus Gold power supply, Xeon W-2235, eight 32 GB DDR4 2933 ECC modules, 4 TB NVMe SSD, Quadro P5000 with four DisplayPort 1.4 and one DVI-D DL, plus Windows 11 Pro; add your own monitor, keyboard and mouse.

Which memory capacity should I choose for this workstation?

The system arrives with 256 GB (8×32 GB) DDR4 2933 ECC registered; the board supports up to 512 GB if your datasets regularly exceed the factory amount.
