Professional Workstation Performance

This HP Z4 G4 mid-tower workstation is built for engineers, designers and analysts who need certified reliability for 3D CAD, rendering and GPU-accelerated workloads. It ships with Windows 11 Pro and a 1000W 80 Plus Gold power supply for stable operation under load.

Suited for Single-Threaded Professional Apps

The four-core Xeon W-2223 at 3.6GHz with 3.9GHz turbo suits workflows that favour high clock speed over core count, such as certain simulation codes and legacy single-threaded applications. Buyers who want more cores for heavy parallel rendering or virtualisation should look at higher-core-count Xeon W models. The 512GB maximum memory ceiling also limits extremely large in-memory datasets.

Tool-Less Upgrades with ECC Memory Care

Tool-less chassis access simplifies drive and graphics card swaps, while four occupied DIMM slots mean a memory upgrade requires replacing the existing 32GB ECC registered modules. Installers must use DDR4 2666 ECC registered DIMMs to maintain stability; mixing non-ECC or different-speed modules will cause boot failures or reduced reliability.

Questions about this item

What CPU socket must my motherboard have to use the Xeon W-2223 3.6GHz processor?

The Xeon W-2223 requires an LGA 2066 socket; this workstation ships with that socket already populated.

Can I keep my existing DDR4 2666 ECC registered modules when upgrading to the 128GB (4x 32GB) configuration?

Yes, provided they are DDR4 2666 ECC registered DIMMs; the board supports up to 512GB total across eight slots.

How do I confirm the Quadro RTX 5000 16GB is running at full PCIe bandwidth after setup?

Open GPU-Z or NVIDIA Control Panel and verify the link width shows x16 and the memory bus reports 256-bit GDDR6.
