HP Z4 G4 Workstation Xeon W-2235 64GB 4TB NVMe Quadro P4000 8GB Windows 11 Pro

Professional workstation for compute-intensive

The HP Z4 G4 is a mid-tower business desktop built around an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo frequency across six cores. It ships with 64 GB of DDR4 2933 ECC registered memory configured as four 16 GB modules and a 4 TB PCIe NVMe solid-state drive. An NVIDIA Quadro P4000 graphics card with 8 GB of GDDR5 memory and a 256-bit interface drives up to four DisplayPort 1.4 outputs for multi-monitor professional visualisation.

Tool-less chassis access simplifies hardware

The mid-tower design provides toolless entry to internal components, allowing straightforward installation of additional storage drives or expansion cards into the available PCIe slots. The system includes a 1000 W 80 Plus Gold power supply rated at 90 % efficiency to support demanding configurations. Builders must verify that any added components fit within the physical constraints of the chassis and the power budget of the installed supply.

DDR4 2933 ECC memory scales to 512 GB maximum

The platform supports up to 512 GB of DDR42933 ECC SDRAM when populated with a Xeon processor, enabling large dataset handling beyond the factory 64 GB. Storage expansion uses a combination of SATA and PCIe NVMe interfaces across multiple internal bays and M.2 slots, though the specific lane allocation for each slot is not detailed. The LGA 2066 socket limits processor upgrades to compatible Xeon W and Core X-series parts within the same generation.
