Professional dual-Xeon workstation

The HP Z8 G4 is a rackmount workstation equipped with two Intel Xeon Gold 6154 processors, each running at 3.00GHz with 20 cores for a total of 36 cores. It ships with 512GB of DDR4 memory and a 1TB SATA SSD, while an NVIDIA Quadro P5000 graphics card handles professional visual tasks. Windows 11 Pro is preinstalled for immediate deployment in engineering, rendering or data-analysis environments.

DDR4 memory ceiling and processor limit

The system supports DDR4 memory up to a maximum capacity of 1536GB, allowing future expansion beyond the installed 512GB. Only two processor sockets are available and both are already populated, so no further CPU upgrades are possible. Storage expansion is limited to four 3.5-inch drive bays, and the operating system drive uses the SATA interface rather than a faster protocol.

Rackmount build with front status LEDs

A rackmount chassis weighing 60 units fits standard server cabinets and includes front-panel LEDs for power, Ethernet and USB status. The Quadro P5000 provides dedicated graphics outputs for multi-display CAD or content-creation setups. Four 3.5-inch bays allow additional hard drives or SSDs to be added internally, while the preinstalled Windows 11 Pro environment is ready for professional applications out of the box.

Questions about this item

Should I pick the single-processor or dual-processor version of this Z8 G4?

The unit ships with two Xeon Gold 6154 processors already installed, delivering 36 cores total, and the board supports a maximum of two CPUs.

What does the 36-core figure mean for rendering and simulation workloads?

Thirty-six cores at 3.00GHz provide high parallel throughput for multi-threaded rendering, CFD and large-assembly CAD tasks, backed by 512GB of DDR4 memory.

How does the SATA interface affect the 1TB SSD and the four 3.5" drive bays?

The boot drive is a 1TB SATA SSD, and the four 3.5-inch bays accept SATA hard drives or SSDs, limiting each bay to SATA transfer speeds.
