HP Z4 G4 Xeon W-2135 128GB 500GB NVMe 2TB P1000

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.
