Professional workstation for design and engineering

The HP Z4 G4 tower is built for professional work such as design, content creation, rendering, engineering, and data-heavy applications. It ships with Windows 11 preinstalled for an out-of-box setup experience. A single Intel Xeon W-2135 six-core processor running at 3.7GHz provides responsive performance for demanding professional tasks. The system includes 8GB of DDR4 ECC memory and a 500GB NVMe SSD paired with a 2TB SATA drive.

Sustained multi-core performance with ECC memory

The Xeon W-2135 delivers 6 cores and 12 threads via hyperthreading, maintaining clock speeds across extended rendering or simulation workloads. Four-channel DDR4 ECC memory at up to 2666MHz supplies bandwidth for large datasets while correcting single-bit errors. The onboard SATA controller supports RAID 0, 1, 5, and 10 across six 6.0 Gb/s channels for redundant or striped storage arrays. Two internal 3.5-inch bays with acoustic dampening rails accommodate additional drives.

Quadro P1000 thermals and 750W power

The NVIDIA Quadro P1000 with 4GB GDDR5 drives up to four displays via Mini DisplayPort 1.4 for CAD and multi-monitor workflows. The 750W chipset powers the CPU, GPU, and storage without redundant hot-swap capability. Front-accessible 5.25-inch bays and a dedicated 9.5mm slim optical bay allow airflow through the tower chassis. Optional Thunderbolt 3 and USB 3.1 Gen 2 expand I/O for external storage or peripherals.

Questions about this item

How much power does the 750 W supply draw when the Xeon W-2135 and Quadro P1000 run full tilt all day?

The unit ships with a 750 W power supply; the Xeon W-2135 is a 6-core 3.7 GHz processor and the Quadro P1000 is a 4 GB GDDR5 card, so sustained load will stay within that 750 W budget.

Which display cables or adapters do I need to use the four Mini DP 1.4 outputs on the Quadro P1000?

The Quadro P1000 provides four Mini DisplayPort 1.4 connectors; you will need Mini DP-to-DisplayPort cables or Mini DP-to-HDMI adapters for each monitor you attach.

Will my existing DDR4-2666 ECC DIMMs work in the eight memory slots of this Z4 G4?

Yes — the board has eight DDR4 slots running in four-channel mode up to 2666 MHz and supports ECC memory, so compatible DDR4-2666 ECC modules can be installed directly.
