Professional workstation for CAD and rendering

The HP Z4 G4 tower is built for professional work such as design, content creation, rendering, engineering and data-heavy applications. A single Intel Xeon W-2135 six-core processor running at 3.7GHz with 12 threads handles demanding tasks. 16GB of DDR4 ECC memory and a 1TB NVMe SSD support smooth multitasking and quick access to project files. The NVIDIA Quadro P1000 with 4GB GDDR5 drives professional visual workflows and multi-display setups.

Sustained performance under load

Four-channel memory architecture up to 2666MHz DDR4 ECC feeds the processor during extended rendering or simulation sessions. The 750W power supply delivers stable current to the CPU and Quadro P1000 without redundant hot-swap capability. Onboard SATA controller with RAID 0, 1, 5 and 10 maintains data throughput across the 1TB NVMe and 2TB 7.2K SATA drives. Two LAN ports provide reliable network connectivity for long-running jobs.

Tower chassis with expansion flexibility

The tower frame includes two internal 3.5-inch bays with acoustic dampening rails, two external 5.25-inch bays and a dedicated 9.5mm slim optical bay housing a DVD +/- RW drive. Graphics expansion supports two PCI Express x16 Gen 3 cards, while the Quadro P1000 offers four Mini DisplayPort 1.4 outputs. Front and rear I/O provide USB 2.0, USB 3.1 Gen 1 and optional USB 3.1 Gen 2 plus optional Thunderbolt 3 for peripheral growth. Windows 11 is preinstalled for immediate deployment.

Questions about this item

How loud and hot does the 750W power supply run under sustained loads?

The 750W unit powers the Xeon W-2135 and Quadro P1000 without redundant or hot-swap features; acoustic dampening rails on the 3.5" bays help reduce drive noise during all-day operation.

Which display cables or adapters do I need for the Quadro P1000's Mini DP 1.4 outputs?

The card provides four Mini DisplayPort 1.4 connectors, so you will need Mini DP to DisplayPort, HDMI or DVI cables or adapters matching your monitors.

Can I keep my existing DDR4 ECC modules and install them in the eight DIMM slots?

Yes, the board offers eight DDR4 slots running up to 2666MHz in a four-channel layout and supports up to 512GB total with ECC registered DIMMs.
