Mid-tower workstation for professional workflows

The HP Z4 G4 is a business desktop built around a single Intel Xeon W-2225 processor running at 4.1GHz with a 4.6GHz turbo frequency. It ships with 64GB of DDR4 2933 ECC registered memory in a four-by-16GB configuration and a 4TB PCIe NVMe solid-state drive. An NVIDIA Quadro P2000 graphics card with 5GB GDDR5 memory and four DisplayPort 1.4 outputs drives visual workloads. Windows 11 Pro is pre-installed.

Memory ceiling and graphics interface limits

The platform supports a maximum of 512GB DDR4 2933 ECC SDRAM when configured with a Xeon processor. The Quadro P2000 connects through a 160-bit memory interface and provides four DisplayPort 1.4 connectors for multi-monitor setups. Storage expansion relies on internal bays and M.2 slots that accept SATA and PCIe NVMe drives. A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers power to all installed components.

Check processor socket.

Before ordering, verify that your intended processor uses the LGA 2066 socket supported by this chassis. Confirm that any additional memory modules are DDR4 2933 ECC registered DIMMs to match the installed 64GB kit. Ensure the 1000W power supply has the required connectors for any graphics card or storage upgrades you plan to add. The mid-tower form factor provides multiple PCIe slots and toolless access for internal changes.

Questions about this item

Should I choose the 4 TB NVMe SSD or add a SATA drive for more capacity?

The 4 TB NVMe SSD provides fast system responsiveness and high-capacity project storage; internal bays and M.2 slots allow adding SATA drives later if you need additional space.

What does the 4.6 GHz turbo frequency deliver in daily work?

The Xeon W-2225 reaches 4.6 GHz turbo on up to four cores, accelerating single-threaded CAD and simulation tasks while the 4.1 GHz base clock sustains steady multi-core throughput.

How many DisplayPort 1.4 monitors can the Quadro P2000 drive?

The Quadro P2000 includes four DisplayPort 1.4 outputs, each supporting 5K at 60 Hz, so you can connect up to four high-resolution displays directly.
