HP Z4 G4 Workstation

This HP Z4 G4 mid-tower workstation runs an Intel Xeon W-2235 processor at 3.8 GHz with a 4.6 GHz turbo boost. It ships with 64 GB of DDR4 2933 ECC registered memory and a 4 TB PCIe NVMe solid-state drive. Windows 11 Pro is pre-installed for immediate deployment in professional environments.

Professional graphics and reliability

The Nvidia Quadro RTX 5000 provides 16 GB of GDDR6 memory on a 256-bit bus with four DisplayPort 1.4 outputs and VirtualLink. ISV certification and a 1000 W 80 Plus Gold power supply support stable operation for 3D CAD, rendering and GPU-accelerated workloads. Buyers needing dual-GPU configurations or higher core counts should consider other platforms.

512 GB maximum memory capacity

Four memory slots support up to 512 GB of DDR4 2933 ECC SDRAM, allowing future expansion for large datasets and complex simulations. This ceiling determines whether the system can grow with evolving project requirements.

Questions about this item

How loud does the 1000W 80 Plus Gold power supply run under sustained load?

The 1000W 80 Plus Gold unit delivers 90% efficiency, so less waste heat reaches the fans. HP's thermal design keeps acoustics low during long render or simulation sessions.

Which display cables do I need for the Quadro RTX 5000's four DisplayPort 1.4 outputs?

The card provides four DP 1.4 connectors and a VirtualLink port. Bring DisplayPort 1.4 cables for each monitor; adapters are required for HDMI or DVI screens.

Will my existing DDR4 2933 ECC RDIMMs work alongside the installed 64GB kit?

Yes. The four populated slots use DDR4 2933 ECC registered modules. The board supports up to 512GB total, so matching ECC RDIMMs can be added in the free slots.
