Professional Workstation for Compute-Intensive Tasks

The HP Z4 G4 Mid-Tower Workstation is built for professionals who need reliable single-processor performance. An Intel Xeon W-2223 3.6GHz 4-core processor with 3.9GHz Turbo drives demanding applications. 16GB DDR4 2666MHz ECC Registered memory and a 4TB PCIe NVMe SSD support large datasets and fast system responsiveness. Windows 11 Pro 64-bit is pre-installed for immediate deployment.

Quadro RTX 4000 Enables Certified Visualisation

The Nvidia Quadro RTX 4000 8GB GDDR6 256-bit graphics adapter provides 3x DisplayPort 1.4 and 1x USB-C outputs for multi-display setups. ISV certification ensures tested compatibility with leading professional applications for 3D CAD, rendering and visualisation. This GPU accelerates GPU-accelerated workloads where consumer cards lack certified drivers. Buyers who need higher VRAM or multi-GPU scaling must look elsewhere.

DDR4 2666 Operation Limits Memory Throughput

Although the platform supports up to 512GB DDR42933 ECC SDRAM, the supplied 2x 8GB modules run at DDR4 2666 speed. Filling additional slots with faster DDR42933 modules will downclock to the lowest common speed. The LGA 2066 socket and 1000W 80 Plus Gold 90% efficient power supply support expansion within the mid-tower chassis. Builders who need maximum memory bandwidth from day one should specify faster modules at purchase.

Questions about this item

What DDR4 ECC registered modules and how many DIMM slots are used by the factory 16 GB configuration?

The system ships with two 8 GB DDR4 2666 ECC registered DIMMs, occupying two of the eight available slots and leaving room to expand toward the 512 GB maximum.

Which component hits its thermal or power ceiling first when the Xeon W-2223 and Quadro RTX 4000 run sustained workloads?

The 1000 W 80 Plus Gold supply delivers ample headroom; the 8 GB GDDR6 frame buffer on the Quadro RTX 4000 is the practical limit for large GPU-accelerated datasets before system memory becomes a factor.

How loud is the workstation and what is its typical power draw when the CPU and Quadro RTX 4000 run all day?

The 1000 W 80 Plus Gold unit runs efficiently at 90 %; fan speed scales with combined CPU and GPU thermal load, so acoustics stay low at idle and rise only under continuous heavy compute.
