Professional tower workstation

The HP Z8 G4 is a dual-processor tower workstation built for professional design, content creation, rendering and engineering workloads. It ships with two Intel Xeon Gold 6148 CPUs running at 2.40GHz, providing 40 total cores and 80 threads with hyperthreading. Windows 11 Professional is preinstalled for immediate deployment.

Sustained multi-core throughput

Six-channel DDR4 ECC memory runs at 2666MHz across 24 DIMM slots, feeding both processors for consistent performance during long rendering or simulation jobs. The 250GB NVMe SSD on a PCIe adapter card delivers fast boot and project load times. Dual Xeon architecture maintains clock speeds under continuous load without the throttling typical of single-socket designs.

Thermals and power in daily use

An 1125W power supply rated at 90% efficiency at 100V feeds the system, including the NVIDIA Quadro P2000 with 5GB GDDR5 and four Mini DP 1.4 outputs. Four internal 3.5-inch bays include acoustic dampening rails to reduce drive noise. Expansion slots support up to four PCIe x16 Gen3 graphics cards with dedicated 6+2-pin power cables included.

Questions about this item

How much power does the 1125W supply draw when the dual Xeon Gold 6148 CPUs and Quadro P2000 run continuously?

The workstation uses an 1125W power supply rated at 90% efficiency with dual 2.40GHz Xeon Gold 6148 processors and an NVIDIA Quadro P2000 graphics card.

Which DDR4 ECC modules must I already have to reach the 3TB maximum across the 24 DIMM slots?

The system supports six-channel DDR4 ECC memory up to 2666MHz with dual CPUs, providing 24 DIMM slots (12 per processor) for expansion up to 3TB total capacity.

Will my existing SATA 6.0 Gb/s drives work in the four internal 3.5-inch bays with the onboard RAID controller?

Yes, the workstation includes four internal 3.5-inch bays with acoustic dampening rails, a 10-channel SATA 6.0 Gb/s interface, and onboard RAID supporting levels 0, 1, 5 and 10.
