Professional Workstation Platform

The HP Z4 G4 mid-tower workstation is built for engineers, designers and analysts who need certified single-processor performance. It pairs an Intel Xeon W-2225 4-core CPU with 64GB of DDR4 2933 ECC registered memory and a 4TB NVMe SSD for fast project access. The NVIDIA Quadro P4000 8GB GDDR5 graphics card drives up to four DisplayPort 1.4 monitors. Windows 11 Pro is pre-installed and digitally activated.

Sustained Load Behaviour

A 1000W 80 Plus Gold power supply rated at 90% efficiency delivers stable power during long rendering or simulation sessions. The Xeon W-2225 runs at a 4.1GHz base clock with a 4.6GHz turbo frequency, while the ECC memory corrects single-bit errors to protect data integrity. Tool-less chassis access allows quick component swaps without interrupting airflow or requiring specialised tools.

Deciding Specification

The LGA 2066 socket and Xeon W-2225 processor define the platform's 512GB maximum memory ceiling and its certified ISV application support. Buyers who need dual-socket scaling or higher core counts per socket should evaluate alternative chassis configurations. The four DisplayPort 1.4 outputs and 256-bit GPU memory bus set the display and bandwidth limits for visualisation workloads.

Questions about this item

How much heat and power does the 1000W 80 Plus Gold supply draw when the Xeon W-2225 runs at 4.6GHz Turbo all day?

The 1000W 80 Plus Gold unit delivers up to 90% efficiency, so sustained 4.6GHz Turbo loads on the 4-core Xeon W-2225 stay well within its thermal and power envelope.

Which display connectors must my monitors already have for the Quadro P4000 8GB GDDR5 256-bit card?

The Quadro P4000 provides four DisplayPort 1.4 outputs, so each monitor needs a DisplayPort 1.4 input or an active adapter to HDMI or DVI.

Can I keep my existing DDR4 2933 ECC registered modules and reach the 512GB maximum supported capacity?

Yes, the four installed 16GB DDR4 2933 ECC registered sticks leave four slots free, allowing you to add matching modules up to the 512GB limit.
