HP Z4 G4 Xeon Workstation

The HP Z4 G4 is a tower workstation built for professional design, engineering and content-creation workloads. An Intel Xeon W-2135 six-core processor at 3.7 GHz, 128 GB of DDR4 ECC memory and a 500 GB NVMe drive provide responsive performance for large project files. An NVIDIA Quadro P1000 with 4 GB GDDR5 drives up to four displays via Mini DisplayPort 1.4. Windows 11 is preinstalled and ready to use.

Who this suits and who should look elsewhere

This workstation suits CAD designers, video editors and engineers who need certified drivers, ECC memory and multi-display support in a single-processor tower. Buyers who require dual-socket CPU scaling, more than 128 GB of installed memory, or a higher-tier GPU for intensive 3D rendering should consider other configurations. The single 465 W power supply and single processor slot limit future expansion.

The specification that decides fit

The 128 GB DDR4 ECC memory kit fills all eight DIMM slots at the platform maximum of 2666 MHz, so no further memory upgrades are possible without removing modules. If your workflow demands more than 128 GB of installed RAM, this system cannot meet that need.

Questions about this item

Will the 465W power supply sustain the Xeon W-2135 and Quadro P1000 at full load all day?

The 465W unit is rated for the installed Xeon W-2135 and Quadro P1000 configuration under sustained professional workloads.

How loud does the tower get when the CPU and GPU run continuously?

Internal 3.5-inch bays use acoustic dampening rails and the workstation chassis is designed for quiet operation during extended render or compute tasks.

Does the 128GB DDR4 ECC kit fill all eight DIMM slots or leave room to expand?

The 128GB DDR4 ECC memory occupies four of the eight slots at 2666MHz, leaving four slots available for future upgrades up to 512GB total.
