Dual Xeon Gold 6136 workstation

This HP Z8 G4 workstation ships with two Intel Xeon Gold 6136 processors running at 3.00GHz, providing 24 total cores for professional workloads. It targets engineers, designers and data analysts who need certified stability for CAD, rendering and large-dataset tasks. Windows 11 Pro is pre-installed and the unit is sold new. The chassis weighs 55 units and includes status LEDs for power, Ethernet and USB.

128GB DDR4 and Quadro P4000

The system arrives with 128GB of DDR4 memory installed and supports expansion up to 1536GB for larger projects. A 1TB SATA SSD handles operating system and active project storage with fast sequential access. The NVIDIA Quadro P4000 adds dedicated graphics power for multi-display CAD and content-creation pipelines. These components are integrated and tested together before shipment.

Four 3.5-inch drive bays

Internal expansion is limited to four 3.5-inch bays, so storage growth relies on those slots or external arrays. The motherboard accepts a maximum of two processors, both sockets are already populated, so CPU upgrades are not possible. Buyers who need more than four internal drives or additional CPU sockets should consider a different platform. The 55-unit weight also requires a sturdy rack or bench.

Questions about this item

How much additional DDR4 memory can I install beyond the 128GB already fitted?

The motherboard accepts up to 1536GB of DDR4 in total, leaving room for further expansion when larger modules are needed.

Which component will hit its thermal ceiling first when both Xeon Gold 6136 CPUs run at 3.00GHz continuously?

The dual 24-core Xeon package is the primary heat source under sustained load, so the chassis airflow and CPU coolers become the limiting factor before the Quadro P4000 or SSD reach their limits.

How loud are the system fans when the workstation runs rendering jobs all day?

The Z8 G4 uses thermally controlled fans that ramp up under heavy CPU and GPU load; expect audible but not extreme airflow noise during extended 3.00GHz workloads.
