Professional Workstation Configuration

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor with six cores running at 3.8 GHz and a 4.6 GHz turbo frequency. It ships with 256 GB of DDR4 2933 ECC registered memory installed as eight 32 GB modules. A 4 TB PCIe NVMe solid-state drive provides the primary storage volume. Windows 11 Pro is pre-installed and digitally activated.

Included Graphics and Power

An NVIDIA Quadro P2000 card with 5 GB of GDDR5 memory on a 160-bit bus adds four DisplayPort 1.4 outputs for multi-monitor professional visualisation. The system is powered by a 1000 W 80 Plus Gold supply rated at 90 percent efficiency. Integrated gigabit ethernet and high-definition audio handle baseline connectivity and sound without additional cards.

Platform Limits and Expansion

The LGA 2066 platform supports a maximum of 512 GB of DDR4 memory across its available slots. Internal storage expansion relies on a combination of SATA and PCIe NVMe interfaces within the chassis. Professional application certification covers the configured hardware stack, though buyers needing GPU compute beyond 5 GB of video memory or dual-processor scaling will require a different platform class.

Questions about this item

Will the 256GB DDR4 2933 ECC Registered memory need matched modules if I expand toward the 512GB limit?

Yes, the board takes DDR4 2933 ECC Registered DIMMs; the current 8×32GB layout fills eight slots, so any upgrade means replacing modules with matched higher-capacity kits to keep quad-channel performance.

What thermal ceiling appears first when the Xeon W-2235 runs at 4.6GHz Turbo across all six cores for hours?

The 1000W 80 Plus Gold supply and mid-tower airflow are built for the processor's sustained turbo, so the CPU's own thermal throttle point is the first limit you will hit under continuous all-core load.

How loud does the workstation get when the Quadro P2000 and Xeon push 1000W supply load all day?

The 1000W 80 Plus Gold unit runs its fan only as fast as needed; at typical professional loads the system stays in the low-decibel range, ramping noticeably only when both CPU and GPU sustain maximum output together.
