Professional CAD Workstation

The HP Z4 G4 tower workstation pairs an 18-core Intel Core i9-10980XE processor running at 3.0 GHz with an NVIDIA RTX 4000 graphics card equipped with 16GB of memory. A 512GB NVMe drive provides fast storage for active projects. The system ships with Windows 11 Pro installed.

Engineers and 3D Artists

This configuration suits professionals running CAD, rendering, and visualization workloads that benefit from high core counts and certified professional graphics drivers. The 16GB of installed DDR4 memory and single NVMe drive may limit users handling very large datasets or running multiple virtual machines simultaneously. Buyers needing registered ECC memory or Xeon processor support should consider a different platform.

LGA 2066 X299 Platform

The motherboard uses the Intel X299 chipset with an LGA 2066 socket designed exclusively for Core X-Series processors and non-ECC unbuffered DDR4 across eight DIMM slots. It does not support Xeon processors or registered ECC server memory. The 1000W power supply and PCIe Gen 3 slots provide headroom for additional graphics or capture cards.

Questions about this item

What PCIe generation does the Z4 G4 motherboard use for expansion cards and what bandwidth does that cap?

The motherboard provides PCIe Gen 3 slots, so add-in graphics or capture cards are limited to Gen 3 bandwidth.

What physical clearance and power connections does the installed RTX 4000 require inside the tower?

The card occupies a full-height, double-width PCIe slot and draws auxiliary power from the 1000W supply via standard PCIe power cables.

How is the 16 GB DDR4 memory installed across the eight slots, and which population rule is often missed?

The 16 GB ships in a quad-channel configuration; populating all four channels with matched DIMMs is required for full bandwidth.
