Workstation with 128GB DDR4

The HP Z2 G4 Mid-Tower workstation pairs a six-core Intel Core i5-9500 processor with 128GB of DDR4 2666 memory and a 500GB NVMe SSD. An NVIDIA Quadro RTX 4000 graphics card with 8GB GDDR6 provides professional visualisation. Windows 11 Pro is pre-installed on this new system.

Suits ISV-certified workflows.

This configuration fits engineers and designers running certified CAD, BIM or DCC applications that rely on Quadro drivers and large system memory. Buyers who need multi-GPU render farms, ECC memory protection or greater NVMe capacity should evaluate alternative platforms.

Quadro RTX 4000 8GB GDDR6 decides fit

The single specification that determines suitability is the NVIDIA Quadro RTX 4000 with 8GB GDDR6 on a 256-bit bus. It delivers hardware-accelerated ray tracing and AI features for professional viewports. If your workload demands more VRAM or higher compute throughput, this card will be the limiting factor.

Questions about this item

How do I install the 4x 32GB DDR4 2666MHz memory modules into the four DIMM slots?

Power off the workstation, open the mid-tower side panel, align each module notch with the slot key, press down firmly until the retention clips click on both sides, then close the case and power on to confirm 128GB is recognised.

Which component will need replacement first if the 500W 90% efficient power supply degrades over time?

The 500W 90% efficient power supply unit itself is the primary replaceable component; swap it with another standard ATX supply rated at 500W or higher to restore stable delivery to the Quadro RTX 4000 and i5-9500.

What thermal limit appears first when the Intel Core i5-9500 runs at 4.4GHz Turbo under sustained load?

The CPU will hit its maximum junction temperature and throttle the 4.4GHz Turbo frequency down to the 3.0GHz base clock to stay within its thermal design envelope.
