Workstation for Demanding Professional Workflows

This HP Z4 G4 mid-tower workstation targets engineers, designers and analysts who need certified single-processor performance. It ships new with Windows 11 Pro and an Intel Xeon W-2225 processor reaching 4.6 GHz turbo across four cores. The platform supports up to 512 GB of DDR4 ECC memory for large datasets and complex simulations.

ECC Memory and Quadro Graphics in a Serviceable

Four 8 GB DDR4 2933 ECC registered modules provide 32 GB of reliable capacity out of the box. The Nvidia Quadro RTX 5000 adds 16 GB GDDR6 on a 256-bit bus with four DisplayPort 1.4 outputs and VirtualLink. A 1000 W 80 Plus Gold power supply and toolless internal access simplify future upgrades and maintenance.

Replaces Older Single-Socket Towers

This system upgrades from earlier workstations that lack certified RTX professional graphics or sufficient ECC memory bandwidth. The jump is worth it when workflows demand ISV-certified stability for 3D CAD, rendering, visualization or GPU-accelerated compute. Buyers who need dual-processor scaling or higher core counts should consider larger platforms.

Questions about this item

Does the 500 GB NVMe drive use PCIe Gen 3 or Gen 4 speeds?

The 500 GB M.2 NVMe SSD connects via PCIe. The workstation uses an Intel Xeon W-2225 processor with an LGA 2066 socket, which provides PCIe 3.0 lanes.

What physical space and power does the Quadro RTX 5000 need inside the mid-tower?

The Quadro RTX 5000 is a dual-slot card with a 256-bit GDDR6 memory bus. It fits the full-height PCIe x16 slot and draws power from the 1000 W 80 Plus Gold supply via auxiliary connectors.

How do I add more DDR4 ECC memory and which slots do I populate first?

Install DDR4 2933 ECC Registered DIMMs in the eight slots. Populate the four black slots first (one per channel), then the four white slots, to reach the 512 GB maximum.
