Professional CAD Workstation

The HP Z4 G4 tower workstation is built for professional design, content creation, rendering and engineering tasks. It runs on a six-core Intel Xeon W-2135 processor at 3.7GHz with 12 threads. The system includes 32GB of DDR4 ECC memory and a 500GB NVMe SSD. An NVIDIA Quadro P1000 graphics card with 4GB GDDR5 drives up to four displays via Mini DP 1.4 ports. Windows 11 is preinstalled.

Suited For And Not Suited For

This workstation suits professionals who need certified stability for CAD, rendering and multi-display workflows with ECC memory protection. The four-channel DDR4 architecture supports up to 512GB total capacity across eight DIMM slots. Buyers who need redundant hot-swap power supplies or more than two full-length PCIe x16 Gen 3 graphics cards should consider other platforms. The single-processor design also limits maximum core count for heavily threaded compute clusters.

Setup Compatibility Check

Verify that your peripherals match the available Mini DP 1.4 video outputs or plan for adapters. Confirm your storage expansion needs fit two internal 3.5-inch bays, two external 5.25-inch bays and one 9.5mm slim optical bay. The onboard SATA controller supports RAID 0, 1, 5 and 10 across six 6.0 Gb/s channels. Optional Thunderbolt 3 and USB 3.1 Gen 2 require separate add-in cards. The 465W chipset rating defines the platform power envelope for additional components.

Questions about this item

Do I need to add any DDR4 ECC memory modules to reach the 32GB already installed?

No, the workstation ships with 32GB of DDR4 ECC memory installed across its eight DIMM slots, so no extra modules are required for the listed capacity.

Can I keep using my existing SATA hard drives with the onboard 6 Gb/s controller?

Yes, the onboard SATA controller provides six 6.0 Gb/s channels that support RAID 0, 1, 5 and 10, so your current SATA drives will connect and work normally.

How can I verify the Quadro P1000 is running at full performance after setup?

Open the NVIDIA Control Panel or GPU-Z and confirm the card shows 4GB GDDR5 memory, four Mini DisplayPort 1.4 outputs and a driver version that matches the latest Quadro release.
