Dual 18-core Xeon workstation

The HP Z8 G4 delivers 36 total cores across two Intel Xeon Gold 6154 processors running at 3.00GHz. It targets engineers, designers and data analysts who need sustained multi-threaded performance for rendering, simulation and large-model CAD work. 128GB of DDR4 memory and a 512GB NVMe drive support heavy multitasking and fast project loading out of the box.

DDR4 ceiling and GPU scope

Memory can be expanded to 1536GB using DDR4 modules only; no other memory generation is compatible. The NVIDIA Quadro P5000 handles professional visual workloads such as CAD, content creation and multi-display setups, while four 3.5-inch bays provide internal storage expansion. Windows 11 Pro is preinstalled for immediate deployment.

Rackmount footprint and power planning

This unit is a rackmount chassis weighing 60 units, so confirm rack depth, rail clearance and available U-space before ordering. Verify that your facility power circuits and PDU capacity match dual high-wattage Xeon processors plus a dedicated Quadro card. Ensure the operating environment meets thermal requirements for a 36-core workstation running sustained loads.

Questions about this item

Is the 128 GB DDR4 memory enough, or should I plan to add more?

The system ships with 128 GB of DDR4 installed and supports up to 1536 GB total, so you can start with the factory amount and expand later if your workloads grow.

What does the 3.00 GHz Xeon Gold 6154 speed mean when both 18‑core CPUs are running real workloads?

Each of the two Xeon Gold 6154 processors runs at 3.00 GHz across its 18 cores, giving 36 cores of sustained frequency for rendering, simulation and multi‑threaded compute tasks.

How does the 512 GB NVMe drive connect and what performance ceiling should I expect?

The 512 GB NVMe drive uses the platform's PCIe lanes, providing fast sequential access for operating system boots, application launches and active project files.
