Professional Mid-Tower Workstation

The HP Z4 G4 is a new mid-tower workstation built around an Intel Xeon W-2225 processor running at 4.1 GHz with a 4.6 GHz turbo frequency across four cores. It ships with 16 GB of DDR4 2933 ECC registered memory in a two-module configuration and a 2 TB PCIe NVMe solid-state drive. Windows 11 Pro 64-bit is pre-installed and digitally activated.

1000W Gold Power Supply and Professional GPU

A 1000 W 80 Plus Gold power supply rated at 90 percent efficiency delivers power to the Nvidia Quadro RTX 5000 graphics card with 16 GB of GDDR6 memory on a 256-bit bus. The system includes integrated gigabit Ethernet and high-definition audio for standard connectivity. Professional ISV certification ensures stability for compute-intensive applications and large datasets.

Tool-Less Chassis with DisplayPort and VirtualLink

The black chassis provides tool-less access to internal components and multiple PCIe slots for future expansion. The graphics card offers four DisplayPort 1.4 outputs plus a VirtualLink connector for compatible displays. Memory capacity can be increased up to 512 GB using the available DDR4 slots, while additional storage bays support further SATA or PCIe drives.

Questions about this item

How do I install additional DDR4 2933 ECC registered memory in the Z4 G4 mid-tower, and which step do people often miss?

Open the tool-less side panel, seat each DIMM fully until the retention clips click, then populate slots in the sequence shown on the motherboard label — skipping the labelled order is the common mistake.

Which component will need replacement first under continuous heavy workloads on this workstation?

The 1000W 80 Plus Gold power supply is the first part that typically requires replacement after extended sustained loads.

What thermal or power limit appears first when the Xeon W-2225 runs at 4.6 GHz turbo across all cores for long periods?

The CPU hits its package power limit before thermal throttling engages, capping all-core turbo duration.
