Dual Xeon Platinum 8160 workstation

The HP Z8 G4 carries two 18-core Xeon Platinum 8160 processors running at 2.10GHz, delivering 48 threads for professional design, engineering and data-heavy workloads. 128GB of DDR4 memory supports large project files and smooth multitasking. A 512GB NVMe drive provides fast access to applications and everyday working data.

Sustained multi-core throughput

With both processors installed at the maximum of two sockets, the system maintains consistent performance during long rendering, simulation or compute jobs rather than throttling after short bursts. The 128GB DDR4 capacity reduces paging when datasets exceed typical workstation memory, keeping throughput stable across extended sessions.

Rackmount chassis with internal expansion

The 4U rackmount form factor includes four 3.5-inch drive bays for adding high-capacity storage arrays alongside the boot NVMe. Front-panel LEDs show power, Ethernet and USB status at a glance. The dedicated NVIDIA Quadro P4000 handles multi-display CAD and visualisation pipelines without occupying additional expansion slots.

Questions about this item

How loud or hot does the 48-core dual Xeon Platinum 8160 system get when it runs all day?

The workstation uses a rackmount chassis with dual 18-core Xeon Platinum 8160 processors at 2.10GHz, 128GB DDR4 and a Quadro P4000 GPU; fan speed ramps with thermal load, so sustained heavy compute will raise noise and heat output.

What must I already own for this Windows 11 Pro workstation to function?

You need a display with a compatible video input for the Quadro P4000, a keyboard and mouse, and a power source; the unit includes 512GB NVMe storage, 128GB DDR4 and the OS preinstalled.

Will my older DDR4 memory modules work alongside the installed 128GB in this Z8 G4?

The system supports up to 1536GB of DDR4 across its slots; existing DDR4 DIMMs that match the platform's speed and rank requirements can be added to the current 128GB configuration.
