HP Z4 G4 Xeon W-2223 Workstation

The HP Z4 G4 is a mid-tower business desktop built for professional workloads. It runs an Intel Xeon W-2223 quad-core processor at 3.6 GHz with a 3.9 GHz turbo frequency. The system includes 128 GB of DDR4 2666 ECC registered memory and a 500 GB PCIe NVMe SSD. An Nvidia Quadro P5000 with 16 GB GDDR5X drives four DisplayPort 1.4 outputs and a dual-link DVI port. Windows 11 Pro is pre-installed.

Suits memory-heavy workflows not multi-GPU builds

This workstation suits engineers and designers who need large ECC memory capacity and certified professional graphics for CAD, rendering or simulation. The single-processor LGA 2066 platform supports up to 512 GB of DDR4. Buyers who need dual-processor scaling or multiple full-length graphics cards should look at a different platform. The 1000 W 80 Plus Gold supply powers the included configuration with headroom for storage expansion.

128 GB DDR4 2666 ECC registered memory

The installed 128 GB kit uses four 32 GB DDR4 2666 ECC registered modules. This memory type is required for Xeon W-2223 stability and error correction. The board accepts DDR4 up to 512 GB total across eight slots. Selecting non-ECC or unregistered DDR4 will prevent the system from posting. Match the registered ECC specification exactly when adding capacity.

Questions about this item

Does the Xeon W-2223 require an LGA 2066 motherboard socket to operate?

Yes, the Xeon W-2223 uses an LGA 2066 socket which is native to this workstation's board.

Will the Quadro P5000's four DisplayPort 1.4 outputs drive older monitors that only have DVI inputs?

The card includes one DVI-D Dual Link port alongside four DisplayPort 1.4 connectors for direct DVI compatibility.

How can I verify the 128GB DDR4 2666 ECC memory is running at its rated speed after first boot?

Open Task Manager's Performance tab or run CPU-Z to confirm the memory frequency reads 2666 MHz.
