Dual Xeon Gold 6136 tower workstation

The HP Z8 G4 tower ships with two Intel Xeon Gold 6136 processors, each running at 3.00 GHz with twelve cores. Twenty-four physical cores and forty-eight threads handle design, rendering, engineering and data-heavy workloads. Ninety-six gigabytes of DDR4 ECC memory fill the maximum supported capacity across twenty-four DIMM slots. A 1 TB NVMe SSD on a PCIe adapter card provides the primary boot and application drive.

NVIDIA Quadro P4000 and Windows 10 Pro

The installed NVIDIA Quadro P4000 graphics card brings 8 GB of GDDR5 memory and four Mini DisplayPort 1.4 outputs for multi-display CAD and content-creation setups. Windows 10 Professional 64-bit is pre-installed for an out-of-box experience. The chassis includes a DVD+/-RW drive in a dedicated 9.5 mm slim bay and four internal 3.5-inch bays with acoustic dampening rails for additional SATA storage.

Expansion slots and power before ordering

Slot 1 runs at PCIe Gen3 x4 and converts to x8 when the second CPU is present; Slots 2 and 4 are full Gen3 x16, while Slot 3 becomes available only with the second processor installed. Four 6+2-pin graphics power cables are included for up to four full-length cards. The 1125 W power supply is not redundant and does not support hot-swap replacement.

Questions about this item

How much additional DDR4 ECC memory can be added to the 24 DIMM slots beyond the installed 96GB?

The six-channel DDR4 ECC architecture supports up to 3TB total across 24 slots with dual CPUs installed.

What sustained workload constraint appears first when both Xeon Gold 6136 processors and the Quadro P4000 run continuously?

The 1125W power supply delivers the hard ceiling for combined CPU and GPU thermal design power under full load.

How loud are the fans and what heat output should be expected when the workstation runs all day?

Four internal 3.5-inch bays include acoustic dampening rails to reduce airflow noise during extended operation.
