HP Z4 G4 Workstation for compute-heavy workflows

The mid-tower desktop is built around a six-core Intel Xeon W-2235 processor running at 3.8GHz with a 4.6GHz turbo frequency. It ships with 64GB of DDR4 2933 ECC registered memory in four 16GB modules and a 4TB PCIe NVMe solid-state drive. Windows 11 Pro is pre-installed for professional environments.

Memory and storage headroom for large datasets

The platform supports up to 512GB of DDR4-2933 ECC SDRAM, giving ample room to expand beyond the factory 64GB when workloads grow. The 4TB NVMe drive delivers fast system responsiveness and high-capacity project storage, while additional internal bays and M.2 slots allow further SATA or PCIe NVMe combinations.

Professional graphics

An Nvidia Quadro P2000 card provides 5GB of GDDR5 memory on a 160-bit bus and four DisplayPort 1.4 outputs for multi-monitor setups. The workstation is engineered and tested for ISV certification across leading professional applications, ensuring reliable performance for 3D CAD, rendering and GPU-accelerated tasks.

Questions about this item

Will my existing DDR4 2933 ECC registered DIMMs work with the 64 GB (4×16 GB) already installed?

Yes, the board accepts DDR4 2933 ECC registered memory up to 512 GB, so identical modules can be added alongside the factory 64 GB.

How can I verify the Quadro P2000 is running at its full 5 GB GDDR5 160-bit specification after setup?

Open NVIDIA Control Panel or GPU-Z; both will report 5 GB GDDR5 on a 160-bit bus and show driver version and clock speeds matching the card’s spec.

Which cables and adapters ship with the workstation, and what must I source separately for a multi-monitor layout?

The box includes the 1000 W power cord; the Quadro P2000 provides four DisplayPort 1.4 outputs, so you only need DisplayPort cables or DP-to-HDMI adapters for each monitor.
