HP Z4 G4 Workstation

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2223 processor. It ships with 64GB of DDR4 2666 ECC registered memory and a 2TB PCIe NVMe solid-state drive. Professional graphics are handled by an NVIDIA Quadro RTX 5000 with 16GB GDDR6 memory. Windows 11 Pro is pre-installed and digitally activated.

Who this suits

This workstation fits engineers and designers running ISV-certified CAD, rendering or simulation workloads that demand ECC memory and professional GPU drivers. The four-core Xeon at 3.6 GHz with 3.9 GHz turbo handles single-threaded tasks well. Buyers who need more than four CPU cores for heavy multi-threaded compute should consider alternative configurations.

Deciding specification

The Quadro RTX 5000 16GB GPU with four DisplayPort 1.4 outputs and VirtualLink determines suitability for high-end visualisation. Its 256-bit memory interface and certified drivers are the primary factor for professional 3D workflows. Verify that your applications leverage this specific graphics certification before purchasing.

Questions about this item

How do I install the Xeon W-2223 in the LGA 2066 socket without bending pins?

Align the gold triangle on the processor with the socket marker, lower it straight down without pressure, then close the retention lever. The step people miss is skipping the straight vertical drop, which bends the fragile LGA 2066 contacts.

Which DDR4 modules can I add later to reach the 512 GB limit?

Add DDR4 2666 ECC Registered DIMMs in matched sets of four. The board has eight slots; the existing 64 GB uses four, leaving four free for expansion up to the 512 GB maximum.

When does the 1000 W 80 Plus Gold PSU hit its thermal limit during a sustained Quadro RTX 5000 render?

The 1000 W 80 Plus Gold supply is rated for continuous 90 % efficiency at typical loads. Under full GPU and CPU load the unit stays within its thermal envelope; the first limit encountered is usually case airflow rather than the PSU itself.
