HP Z4 G4 Workstation Xeon W-2223 3.6GHz 128GB DDR4 1TB NVMe RTX 5000 16GB

Professional Workstation for Compute-Intensive

This HP Z4 G4 mid-tower workstation targets engineers and content creators who need certified single-processor performance. It ships with an Intel Xeon W-2223 four-core processor running at 3.6 GHz with a 3.9 GHz turbo frequency. The system includes 128 GB of DDR4 2666 ECC registered memory and a 1 TB PCIe NVMe solid-state drive. An Nvidia Quadro RTX 5000 graphics card with 16 GB GDDR6 memory drives professional visualization workloads.

Tool-Less Access Simplifies Hardware Changes

The chassis provides toolless entry to internal components, making memory and storage upgrades straightforward. Four DIMM slots are populated with 32 GB modules, so expanding toward the 512 GB maximum requires replacing existing sticks. The 1000 W 80 Plus Gold power supply supports the installed RTX 5000 and leaves headroom for additional PCIe cards. Ensure the graphics card power connectors match the supply cables before closing the case.

Verify PCIe Clearance

Confirm that your workload benefits from ECC registered DDR4 modules, as standard unbuffered DDR4 will not work in this platform. The motherboard uses an LGA 2066 socket and supports DDR4-2933 speeds, though the installed memory operates at 2666 MHz. Check that the Quadro RTX 5000 length fits your rack or desk enclosure, and that DisplayPort 1.4 or VirtualLink outputs match your display cabling.
