Professional single-processor workstation

This HP Z4 G4 mid-tower workstation delivers professional single-processor performance for demanding workflows. It is built for engineers, designers and analysts who need certified reliability in 3D CAD, rendering, visualization and GPU-accelerated applications. The system ships new with Windows 11 Pro and 128GB of DDR4 2933 ECC registered memory.

Upgrade from consumer desktops

The jump is worth it when ECC memory integrity, ISV-certified drivers and a 1000W 80 Plus Gold power supply become requirements for daily production. Integrated Gigabit Ethernet and High-Definition Audio handle baseline connectivity without extra cards. Tool-less internal access simplifies future changes for IT teams managing fleets.

128GB DDR4 headroom with 512GB maximum capacity

Four 32GB modules occupy half the Xeon W-2225 memory ceiling, leaving room to grow toward 512GB for large datasets and complex simulations. The 500GB PCIe NVMe boot drive provides fast system responsiveness; additional SATA and M.2 bays accept further drives for high-capacity project storage. The Quadro RTX 5000 16GB GDDR6 with four DP 1.4 and VirtualLink outputs drives multi-display visualization workloads.

Questions about this item

What clearance and power connectors does the mid-tower chassis need for the RTX 5000 graphics card?

The 1000 W 80 Plus Gold supply feeds the Quadro RTX 5000 through the chassis PCIe power cables; the mid-tower frame accepts full-height, dual-slot cards up to the standard workstation length.

Which memory slots do the four 32 GB DDR4 2933 ECC modules occupy for correct quad-channel operation?

Install the matched 4×32 GB kit in the four black DIMM slots (one per channel) so the Xeon W-2225 runs at the rated 2933 MT/s; mixing slots drops the system to single-channel speed.

How many additional NVMe drives can be added later, and what form factor do they use?

The Z4 G4 board provides two M.2 PCIe slots; one holds the factory 500 GB NVMe SSD, leaving a second slot open for another M.2 2280 NVMe drive when more capacity is needed.
