HP Z4 G4 Mid-Tower Workstation

This HP Z4 G4 mid-tower workstation arrives new with Windows 11 Pro installed. An Intel Xeon W-2235 processor runs at 3.8 GHz with a 4.6 GHz turbo across six cores. The system includes 256 GB of DDR4 2933 ECC registered memory in eight 32 GB modules and a 2 TB PCIe NVMe solid-state drive.

Suited for memory-heavy professional workloads

The 256 GB DDR4 2933 ECC configuration supports large datasets, complex simulations and ISV-certified applications. The Nvidia Quadro P5000 with 16 GB GDDR5X and four DisplayPort 1.4 outputs drives multi-monitor 3D CAD and visualisation tasks. Buyers who need more than 512 GB total memory capacity or who require a different GPU architecture should evaluate alternative configurations.

Verify power and expansion requirements

The integrated 1000 W 80 Plus Gold supply delivers 90 % efficiency for the installed components. Confirm that your workspace can accommodate a mid-tower chassis and that available PCIe slots match any additional cards you plan to install. The LGA 2066 socket and DDR4 2933 memory standard define future processor and memory upgrade paths.

Questions about this item

Does the 1000W power supply have enough PCIe connectors for the Quadro P5000 16GB card?

The 1000W 80 Plus Gold supply ships with the workstation and is sized for the installed Quadro P5000 16GB, so the required power cables are already fitted.

Can I keep my older SATA SSDs and use the M.2 NVMe slot at the same time?

Yes, the chassis provides multiple internal storage bays plus M.2 slots, so SATA drives and the 2TB PCIe NVMe drive can coexist.

How do I confirm the 256GB DDR4 2933 ECC memory is running at the correct speed?

Open Task Manager > Performance > Memory and verify the speed reads 2933 MHz; the BIOS will also show 8 × 32 GB ECC Registered modules detected.
