HP Z4 G4 workstation Xeon W-2135 3.7GHz 64GB DDR4 250GB NVMe 2TB Quadro P1000

Professional workstation for creators and engineers

The HP Z4 G4 tower is built for professional work such as design, content creation, rendering, engineering, and data-heavy applications. An Intel Xeon W-2135 six-core processor running at 3.7GHz delivers 12 threads for parallel workloads. 64GB of DDR4 ECC memory across eight slots provides capacity for large projects and smooth multitasking. Windows 11 comes preinstalled for immediate setup.

Quiet tower with flexible storage and display

Acoustic dampening rails on two internal 3.5-inch bays reduce drive noise during long sessions. Two external 5.25-inch bays and a dedicated 9.5mm slim optical bay leave room for legacy media or extra accessories. A 250GB NVMe M.2 SSD handles the operating system and active files while a 2TB 7.2K SATA drive stores bulk data. The NVIDIA Quadro P1000 with 4GB GDDR5 drives four Mini DisplayPort 1.4 outputs for multi-monitor configurations. Dual LAN ports and a 750W power supply support steady connectivity and expansion.

Verify memory ceiling

Installed memory already reaches the 64GB maximum listed in the specifications, so no further RAM upgrades are possible on this unit. The motherboard offers two PCI Express x16 Gen 3 slots for additional graphics cards, though power connectors depend on the supply. Optional USB 3.1 Gen 2 and Thunderbolt 3 ports are not included unless specified. Buyers who need more than 64GB of memory or built-in high-speed USB and Thunderbolt should consider a different configuration.
