Professional workstation tower

The HP Z4 G4 is a tower workstation built for professional workloads such as design, content creation, rendering and engineering. A single Intel Xeon W-2135 six-core processor running at 3.7GHz delivers 12 threads for multi-threaded applications. The system ships with 64GB of DDR4 ECC memory and Windows 11 preinstalled.

Four-channel memory and expansion bays

Four-channel DDR4 architecture supports up to 2666MHz speeds across eight DIMM slots, with the current 64GB configuration reaching the listed maximum in the supplied spec sheet. Two internal 3.5-inch bays with acoustic dampening rails and two external 5.25-inch bays provide flexible storage expansion, while a dedicated slim optical bay holds the included DVD+-RW drive.

Quadro P1000 graphics for visual workflows

An NVIDIA Quadro P1000 with 4GB GDDR5 drives up to four displays through Mini DisplayPort 1.4 outputs, supporting CAD, content creation and multi-monitor setups. The 1TB NVMe SSD accelerates application and project-file access. Buyers who need more than 64GB of RAM or multiple high-power GPUs should verify power-supply and memory-ceiling limits before purchase.

Questions about this item

What is the maximum throughput of the onboard SATA interface and which RAID levels does it support?

The onboard SATA controller runs at 6.0 Gb/s across six channels and supports RAID 0, 1, 5 and 10.

Which drive bays are available for additional storage and what are their form factors?

The chassis provides two internal 3.5-inch bays with acoustic dampening rails, two external 5.25-inch bays and one dedicated 9.5mm slim optical bay.

How is the Quadro P1000 installed and what is the common mistake?

The card occupies one PCI Express x16 Gen 3 slot and requires its auxiliary power connector; forgetting to attach that power cable is the step most often missed.
