HP Z4 G4 Workstation for Professional Workflows

This HP Z4 G4 mid-tower workstation is built for demanding professional applications. It features an Intel Xeon W-2235 3.8GHz 6-core processor with 4.6GHz turbo, 256GB DDR4 2933MHz ECC registered memory, and an NVIDIA Quadro RTX 4000 8GB GDDR6 graphics card. The system includes a 4TB PCIe NVMe SSD and ships with Windows 11 Pro.

Suits ECC Memory and Certified GPU Needs.

This configuration suits engineers and designers who require ISV-certified graphics and large ECC memory capacity for data integrity. Buyers who need non-ECC memory compatibility or consumer-grade graphics cards should look at alternative platforms. The workstation targets workflows demanding certified professional application support.

256GB DDR4 2933MHz ECC Registered Memory Decides Fit

The single specification that decides fit is the 256GB DDR4 2933MHz ECC registered memory configuration. This capacity and ECC type are required for large dataset processing and error correction in professional workloads. The system supports a maximum of 512GB, so buyers needing different memory types or capacities must verify compatibility before purchase.

Questions about this item

Does the workstation come with a monitor, keyboard or mouse in the box?

The system includes the tower, a 1000W 80 Plus Gold power supply and Windows 11 Pro pre-installed. Monitor, keyboard and mouse are not included and must be purchased separately.

Should I choose the 256 GB DDR4-2933 configuration or add more memory up to the 512 GB maximum?

The unit ships with 256 GB (8×32 GB) DDR4-2933 ECC registered memory. The Xeon W-2235 platform supports up to 512 GB, so you can expand later if workloads demand it.

What does the 3.8 GHz base / 4.6 GHz turbo figure mean for real rendering performance with the Quadro RTX 4000?

The Xeon W-2235 runs at 3.8 GHz base and can boost to 4.6 GHz on active cores, feeding the RTX 4000’s 8 GB GDDR6 and three DisplayPort 1.4 plus USB-C outputs for GPU-accelerated CAD and rendering.
