Professional Workstation Platform

The HP Z4 G4 mid-tower workstation delivers professional single-processor performance for demanding workflows. It is built around an Intel Xeon W-2235 six-core processor running at 3.8GHz with a 4.6GHz turbo frequency. The system includes 64GB of DDR4 2933 ECC registered memory and a 1TB PCIe NVMe solid-state drive. Nvidia Quadro P4000 graphics with 8GB GDDR5 memory drive professional visualisation tasks. Windows 11 Pro is pre-installed for immediate deployment.

Memory and Storage Constraints

The platform supports a maximum of 512GB DDR4-2933 ECC SDRAM on Xeon configurations, limiting total memory expansion to eight slots. Internal storage combines M.2 slots for PCIe NVMe drives with traditional bays for SATA devices, defining the upgrade path for capacity and speed. The included 1000W 80 Plus Gold power supply operates at 90% efficiency, setting the practical ceiling for additional internal components. Four DisplayPort 1.4 outputs on the graphics card determine the native display connectivity limit.

ECC Registered Memory Requirement

The 64GB configuration uses four 16GB DDR4 2933 ECC registered modules, making ECC registered memory the single specification that decides compatibility for any future memory upgrade. Standard unbuffered DDR4 modules will not function in this workstation. Buyers who need non-ECC memory or higher speeds than 2933MHz must select a different platform. The LGA 2066 socket and Xeon W-series processor line define the processor upgrade boundary within this chassis.

Questions about this item

Should I pick the 64 GB DDR4 2933 kit or add more modules later?

The system ships with 64 GB (4 × 16 GB) DDR4 2933 ECC registered memory and supports up to 512 GB total, so you can expand later if workloads grow.

What does the Xeon W-2235 3.8 GHz base and 4.6 GHz turbo mean for daily CAD renders?

Six cores at 3.8 GHz base with a 4.6 GHz turbo give strong single-thread speed for viewport work and enough multi-thread throughput for moderate render jobs.

How does the Quadro P4000 8 GB GDDR5 256-bit with DP 1.4 connectors perform in a real workstation?

The 8 GB GDDR5 frame buffer and four DisplayPort 1.4 outputs drive multiple 4 K or 5 K displays directly for 3D CAD, visualization and GPU-accelerated tasks.
