HP Z4 G4 Workstation with Xeon W-2235

This HP Z4 G4 mid-tower workstation is built for professionals who need reliable single-processor performance. It ships with Windows 11 Pro installed and includes a 1000W 80 Plus Gold power supply. The system is designed for demanding workflows such as 3D CAD, rendering and GPU-accelerated applications.

Suits memory-heavy tasks, not multi-socket scale

The 256GB DDR4 2933 ECC configuration serves users working with large datasets and complex simulations. The platform supports up to 512GB total, so builders who need more memory capacity than this ceiling should look elsewhere. The single-socket LGA 2066 design also means it is not for workloads requiring dual-processor throughput.

256GB DDR4 2933 ECC decides fit

Eight 32GB registered modules fill the current memory slots and set the baseline for ECC reliability. Adding more memory later requires compatible DDR4 2933 ECC RDIMMs to match the existing speed and error-correction standard. The installed capacity and type are the primary factors in deciding whether this workstation matches your application requirements.

Questions about this item

Will the 1000W power supply and mid-tower chassis clear the Quadro P4000's length and power connectors?

The Z4 G4 mid-tower chassis provides full-length PCIe clearance and the included 1000W 80 Plus Gold PSU supplies the auxiliary power connectors required by the Quadro P4000 8GB card.

Which memory slots do the eight 32GB DDR4 2933 ECC registered modules occupy for correct channel population?

The 256GB kit fills all eight DDR4 slots in the supported Xeon W-2235 configuration; install matched pairs per the motherboard silkscreen to maintain quad-channel operation.

When the 1TB M.2 NVMe boot drive reaches end of life, which replacement drive form factor and interface does the Z4 G4 accept?

The workstation has additional M.2 slots keyed for PCIe NVMe SSDs; any standard M.2 2280 NVMe drive can be installed as a direct replacement.
