Dual Xeon Gold 5122 workstation

The HP Z8 G4 is a tower workstation equipped with two Intel Xeon Gold 5122 processors running at 3.60GHz. It ships with 256GB of DDR4 memory and a 1TB SSD for fast access to projects. An NVIDIA Quadro P4000 graphics card with 8GB GDDR5 drives professional visual workflows. Windows 11 Pro is pre-installed.

Suited for multi-threaded professional workloads

This system targets engineers, designers and content creators who need high core counts and certified GPU drivers for CAD, rendering and simulation. The four 3.5-inch expansion bays allow additional local storage. Buyers who need more than 256GB of memory or a newer GPU architecture should evaluate other configurations.

1536GB maximum memory capacity

The platform supports up to 1536GB of DDR4 across its memory slots, so the installed 256GB can be expanded significantly for larger datasets. This ceiling is the key figure when planning memory-intensive projects.

Questions about this item

How much heat and power should I expect from the dual Xeon Gold 5122 CPUs and the Quadro P4000 when this workstation runs all day?

Two Xeon Gold 5122 processors at 3.60 GHz and an 8 GB GDDR5 Quadro P4000 will generate significant heat under sustained load; the chassis uses multiple system fans and a dedicated GPU cooler to move that heat out through the rear vents.

What other components must I already have for this workstation to operate out of the box?

Only a display with a compatible video input, a keyboard and a mouse are required; Windows 11 Pro is pre-installed, the 1 TB SSD and 256 GB DDR4 are fitted, and the power cord is included.

Will my existing DDR4 memory modules work alongside the installed 256 GB if I want to expand toward the 1536 GB maximum?

Yes, the system accepts standard DDR4 RDIMMs; you can add matching modules to the open slots up to the 1536 GB limit without replacing the factory memory.
