HP Z4 G4 Mid-Tower Xeon W-2235 64GB 500GB NVMe RTX 4000 8GB Windows 11 Pro

Ready-to-run Xeon workstation

This HP Z4 G4 mid-tower arrives configured with an Intel Xeon W-2235 six-core processor running at 3.8 GHz with a 4.6 GHz turbo frequency. It includes 64 GB of DDR4 2933 ECC registered memory and a 500 GB NVMe SSD. The Nvidia Quadro RTX 4000 8 GB GDDR6 graphics card and Windows 11 Pro are installed and ready for professional applications.

Tool-less chassis with professional I/O

The mid-tower enclosure uses a tool-less design for straightforward internal access to PCIe slots, storage bays and memory sockets. A 1000 W 80 Plus Gold power supply rated at 90 % efficiency delivers stable power for the configured components. The Quadro RTX 4000 provides three DisplayPort 1.4 outputs and one USB-C connector supporting 256-bit GDDR6 memory bandwidth. Integrated Gigabit Ethernet and high-definition audio handle networking and sound without extra cards.

Verify CPU socket and memory type before ordering

The system uses an LGA 2066 socket, so any processor upgrade must match that platform. Memory expansion requires DDR4 2933 ECC registered modules to maintain compatibility with the existing 64 GB configuration. The 500 GB NVMe drive occupies one M.2 slot; additional storage will need available SATA or PCIe bays. Buyers who need a different GPU form factor or more than four memory channels should confirm the chassis and motherboard constraints first.
