HP Z4 G4 Business Desktop Xeon W-2223 3.6GHz 64GB DDR4 4TB NVMe RTX 5000 16GB

Professional Workstation for Demanding Workflows

The HP Z4 G4 mid-tower workstation targets professionals who need certified reliability for 3D CAD, rendering and GPU-accelerated applications. It ships with Windows 11 Pro and an Intel Xeon W-2223 four-core processor running at 3.6 GHz with 3.9 GHz turbo. The system includes 64 GB of DDR4 2666 ECC registered memory and a 4 TB PCIe NVMe SSD for fast project storage. An NVIDIA Quadro RTX 5000 with 16 GB GDDR6 provides certified professional graphics support.

PCIe and Memory Limits Define Expansion

The motherboard uses an LGA 2066 socket and supports up to 512 GB of DDR4-2933 ECC SDRAM on Xeon configurations. Four DDR4 slots are populated with 16 GB modules, leaving no free slots for additional memory without replacing existing sticks. The Quadro RTX 5000 connects via PCIe and drives four DisplayPort 1.4 outputs plus VirtualLink. Storage expansion relies on additional M.2 slots and internal drive bays that accept SATA or PCIe NVMe drives. The 1000 W 80 Plus Gold power supply delivers 90 percent efficiency for the configured components.

Toolless Access Simplifies Upgrades

HP designed the Z4 G4 with toolless entry to internal components, making memory, storage and graphics card swaps straightforward. The most common issue is exceeding the 512 GB memory ceiling or populating slots with non-ECC modules that the workstation platform will not recognise. Builders must also verify that any added PCIe cards fit within the mid-tower chassis clearance and the power budget of the 1000 W unit. Buyers who need more than four display outputs or a second GPU should plan for a different platform.
