HP Z4 G4 Mid-Tower Workstation Xeon W-2235 3.8GHz 6 Core 128GB DDR4 4TB NVMe Quadro P4000 8GB Windows 11 Pro

HP Z4 G4 Xeon W-2235 Workstation

This new mid-tower workstation combines an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo frequency and six cores. It is configured with 128 GB of DDR4 2933 ECC registered memory in four 32 GB modules. A 4 TB PCIe NVMe solid-state drive provides the primary storage. The system ships with Windows 11 Pro pre-installed.

Professional graphics and expandability

The NVIDIA Quadro P4000 card supplies 8 GB of GDDR5 memory on a 256-bit bus and four DisplayPort 1.4 outputs for multi-monitor configurations. Integrated gigabit Ethernet and high-definition audio handle networking and sound. The 1000 W 80 Plus Gold power supply delivers 90 percent efficiency. Tool-less access and multiple PCIe slots allow straightforward upgrades for memory, storage or additional cards. Buyers who need more than 512 GB of total memory capacity should consider alternative platforms.

LGA 2066 socket defines CPU compatibility

The motherboard uses the LGA 2066 socket, which determines exactly which Intel Xeon W or Core X-series processors can be installed. Maximum supported memory is 512 GB of DDR4 2933 ECC SDRAM when a Xeon processor is fitted. The 4 TB NVMe drive occupies one M.2 slot; further M.2 or SATA devices can be added in the available bays. Verify that any planned processor upgrade matches the socket and the 1000 W power budget.
