Ready-to-Deploy Workstation

The HP Z4 G4 arrives with Windows 11 Pro installed, a Xeon W-2223 running at 3.6 GHz with 3.9 GHz turbo, 256 GB of DDR4 2666 ECC memory in eight 32 GB modules, a 4 TB PCIe NVMe SSD and a Quadro RTX 5000 16 GB GDDR6 card with four DisplayPort 1.4 outputs and VirtualLink. A 1000 W 80 Plus Gold power supply drives the mid-tower chassis.

Suited for Memory-Bound Professional Loads

Engineers, analysts and content creators who need large ECC memory capacity and certified GPU drivers for 3D CAD, rendering or simulation workloads will use this configuration immediately. Buyers who need more than 256 GB of RAM or multiple GPU slots should look at larger platforms.

256 GB DDR4 2666 ECC Registered Memory

The eight-module kit fills half the 512 GB maximum and provides error-correcting bandwidth for stable operation with large datasets. If the workflow requires the full 512 GB limit or faster DDR4 2933 speeds, the memory configuration must be changed.

Questions about this item

Will the LGA 2066 Xeon W-2223 and Quadro RTX 5000 fit my existing PCIe 3.0 peripherals?

The motherboard uses PCIe 3.0 lanes for the GPU and add-in cards, so existing PCIe 3.0 peripherals will operate at their rated speeds.

How can I confirm the 256 GB DDR4 2666 ECC memory is running correctly after boot?

Open Windows Task Manager, go to the Performance tab, select Memory, and verify the total shows 256 GB with a speed of 2666 MHz.

Does the box include the 1000 W 80 Plus Gold power supply and Windows 11 Pro licence, or must I buy them separately?

The 1000 W 80 Plus Gold PSU and a digitally activated Windows 11 Pro licence are both included; no separate purchase is required.
