Professional CAD Workstation

The HP Z4 G4 is a new tower workstation built for professional design, engineering and rendering tasks. It runs Windows 11 and uses a single Intel Xeon W-2135 processor with six cores at 3.7GHz. The system includes 128GB of DDR4 ECC memory across eight slots and a 500GB NVMe drive paired with a 2TB SATA drive. An NVIDIA Quadro P1000 with 4GB GDDR5 provides certified graphics for CAD and multi-display work.

Suited For Professional Visual Work

This configuration suits buyers who need ECC memory stability and a certified Quadro GPU for CAD, content creation or multi-monitor setups. The four-channel 2666MHz memory architecture supports smooth multitasking with large project files. Builders who require dual-processor scaling, hot-swap power redundancy or more than two internal 3.5-inch drive bays should look at a different platform.

128GB DDR4 ECC At Four-Channel Speed

The installed memory reaches the 128GB maximum for this specific CPU and operates in four-channel mode at 2666MHz with ECC. All eight DIMM slots are populated, so no further memory can be added without removing existing modules. Buyers planning larger datasets must verify that this capacity ceiling matches their workload before purchase.

Questions about this item

Will my existing DDR4 ECC modules rated at 2666 MHz work in the eight DIMM slots of this Z4 G4?

Yes, the board provides eight DDR4 ECC slots running in four-channel mode up to 2666 MHz, so compatible modules you already own can be installed alongside the factory 128 GB.

How can I verify the Quadro P1000 is recognised and running at full PCIe Gen 3 x16 speed after first boot?

Open Device Manager in Windows 11, confirm the NVIDIA Quadro P1000 appears under Display adapters, then run the NVIDIA Control Panel System Information to see the bus reported as PCI Express x16 Gen 3.

Which cables or adapters are included for the 500 GB NVMe and 2 TB SATA drives, and what must I source separately?

The workstation ships with the NVMe drive installed in the M.2 slot and the 2 TB SATA drive mounted with data and power cables connected; no extra cables are needed unless you add more drives.
