HP Z4 G4 Workstation for professional compute

The HP Z4 G4 is a new mid-tower workstation built around an Intel Xeon W-2225 4-core processor running at 4.1 GHz with a 4.6 GHz turbo frequency. It ships with 32 GB of DDR4 2933 ECC registered memory and a 1 TB PCIe NVMe solid-state drive. Windows 11 Pro 64-bit is pre-installed for immediate deployment in business environments.

32 GB DDR4 and 1 TB NVMe capacity

The 32 GB DDR4 2933 configuration handles typical professional datasets and multitasking workloads comfortably. Memory can be expanded to 512 GB on this Xeon platform for larger simulations or rendering tasks. The 1 TB NVMe drive provides fast system responsiveness and project storage, while additional internal bays and M.2 slots allow further SATA or PCIe NVMe expansion when capacity demands grow.

Nvidia Quadro RTX 4000 8 GB GDDR6

The Nvidia Quadro RTX 4000 8 GB GDDR6 256-bit graphics adapter drives up to four displays via three DP 1.4 ports and one USB-C connector, certified for 3D CAD, rendering and GPU-accelerated applications. A 1000 W 80 Plus Gold power supply rated at 90 % efficiency delivers stable power to the CPU, GPU and expansion cards under sustained load. Tool-less chassis access simplifies hardware upgrades and maintenance for IT teams.

Questions about this item

Will my existing DDR4 2933 ECC modules work with the four installed 8 GB sticks?

Yes, the board accepts DDR4 2933 ECC registered memory up to 512 GB, so your modules can be added alongside the factory 32 GB.

How do I verify the Quadro RTX 4000 is running at full 8 GB GDDR6 256-bit with three DisplayPort 1.4 and one USB-C outputs?

Open NVIDIA Control Panel or GPU-Z; they will show 8 GB GDDR6, 256-bit bus, and list 3× DP 1.4 plus 1× USB-C as active connectors.

Does the box contain any SATA cables or drive caddies for extra storage, or must I buy them separately?

The workstation ships with the 1 TB M.2 NVMe SSD installed, Windows 11 Pro licence, and power cord; SATA cables and 3.5-inch drive caddies are not included.
