HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2225 4-core processor running at 4.1 GHz with a 4.6 GHz turbo frequency. It ships with 16 GB of DDR4 2933 ECC registered memory in a 2x 8 GB configuration and a 2 TB PCIe NVMe solid-state drive. Graphics are handled by an Nvidia Quadro P5000 with 16 GB GDDR5X memory and a 256-bit interface. The system includes a 1000 W 80 Plus Gold power supply and Windows 11 Pro 64-bit.

Who this suits and who should look elsewhere

This workstation targets professionals running ISV-certified applications such as 3D CAD, rendering and visualization that benefit from the Quadro P5000's four DisplayPort 1.4 outputs and dual-link DVI. Buyers needing more than 16 GB of memory out of the box or a higher core count for heavy simulation should consider other configurations, as should users who require a monitor included or a smaller chassis for space-constrained desks.

Deciding specification — ECC DDR4 2933 memory

The motherboard supports up to 512 GB of DDR4 2933 ECC registered memory across its slots, which determines whether large datasets and complex assemblies can stay in RAM. If your workflow demands capacity beyond the installed 16 GB, the four-channel architecture and high ceiling allow straightforward expansion with compatible modules.

Questions about this item

How long can the 4.1 GHz Xeon W-2225 sustain its 4.6 GHz turbo before thermal limits throttle it?

The 4-core Xeon W-2225 runs at 4.1 GHz base with a 4.6 GHz turbo; sustained all-core speeds depend on the mid-tower cooling and 1000 W 80 Plus Gold supply.

What noise and heat should I expect from the 1000 W Gold PSU and Quadro P5000 during all-day rendering?

The 1000 W 80 Plus Gold unit runs at 90 % efficiency, reducing waste heat; the Quadro P5000 16 GB GDDR5X and CPU share the mid-tower airflow for continuous loads.

Which ECC DDR4-2933 modules must I already have to reach the 512 GB maximum?

The board accepts DDR4 2933 ECC Registered DIMMs; it ships with 16 GB (2×8 GB) and supports up to 512 GB total across its slots.
