Workstation for compute-heavy workflows

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 3.8GHz 6-core processor with 4.6GHz turbo. It ships with 128GB DDR4 2933 ECC registered memory in a 4x32GB configuration and a 1TB PCIe NVMe SSD. An Nvidia Quadro P4000 8GB GDDR5 graphics card with four DisplayPort 1.4 outputs drives professional visual workloads under Windows 11 Pro.

Suited for ISV-certified applications.

This system targets engineers, designers and analysts running certified CAD, rendering or simulation software that benefits from high single-thread clocks and ECC memory integrity. The single-processor LGA 2066 platform limits buyers who need dual-socket throughput or more than 512GB maximum memory capacity. Workloads requiring more than four DisplayPort 1.4 connectors or a different GPU architecture should evaluate alternative configurations.

1000W 80 Plus Gold PSU

A 1000W power supply rated at 90% efficiency delivers headroom for the Quadro P4000 and additional PCIe cards. Toolless access simplifies installing extra SATA or NVMe drives in the internal bays and M.2 slots. Integrated Gigabit Ethernet and high-definition audio require no extra hardware for network and sound connectivity.

Questions about this item

Does the 128GB DDR4 2933 ECC registered memory require a Xeon W-2235 processor to operate correctly?

Yes, the 128GB DDR4 2933 ECC registered memory is supported on Xeon configurations such as the installed W-2235, enabling the full 512GB maximum capacity.

Can I keep my existing SATA hard drives alongside the 1TB NVMe SSD in the mid-tower chassis?

Yes, the Z4 G4 provides multiple internal storage bays and M.2 slots allowing combinations of SATA and PCIe NVMe drives simultaneously.

How do I verify the Quadro P4000 8GB GDDR5 is running at full 256-bit 1.4 DisplayPort capability after setup?

Check Device Manager for the NVIDIA Quadro P4000 listing and confirm 8GB GDDR5 memory; connect a DisplayPort 1.4 monitor to one of the four DP 1.4 outputs to validate video signal.
