HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a new mid-tower business desktop built around an Intel Xeon W-2223 3.6GHz processor with 3.9GHz turbo across four cores. It ships with 32GB of DDR4 2666 ECC registered memory and a 500GB NVMe SSD. Windows 11 Pro is pre-installed and activated.

Who This Suits And Who It Does Not

This system suits professionals who need certified ISV reliability for 3D CAD, rendering or GPU-accelerated workloads and who value tool-less internal access for future upgrades. Buyers who need more than 512GB of memory capacity or who require a different CPU socket should consider other platforms.

Nvidia Quadro RTX 5000 16GB Graphics

The installed Nvidia Quadro RTX 5000 provides 16GB of GDDR6 memory on a 256-bit bus with four DisplayPort 1.4 outputs plus VirtualLink. This GPU decides whether the workstation meets the graphical demands of your professional applications.

Questions about this item

Does the 1000W 80 Plus Gold supply have the 8-pin and 6-pin PCIe cables the Quadro RTX 5000 requires?

The RTX 5000 draws up to 256 W and needs one 8-pin plus one 6-pin connector; the Z4 G4 1000W unit includes both cables pre-routed.

Which screw secures the M.2 NVMe drive to the motherboard standoff, and where do installers lose it?

A single M2×3 mm screw holds the 500 GB drive; it ships in a small bag taped to the chassis floor — open the bag before tilting the board vertical.

When should the 32 GB DDR4 2666 ECC registered modules be replaced to keep 512 GB maximum capacity?

Run the built-in memory self-test annually; replace any module that logs correctable errors, otherwise the four DIMMs can stay for the platform’s full service life.
