HP Z4 G4 Workstation for Professionals

The HP Z4 G4 tower workstation is built for design, engineering, rendering and data-heavy applications. It ships with an Intel Xeon W-2135 six-core processor running at 3.7GHz and 8GB of DDR4 ECC memory. A 500GB NVMe SSD provides fast access to project files and applications. Windows 11 comes pre-installed for immediate use.

Suited for CAD and Multi-Display Work

The NVIDIA Quadro P1000 with 4GB GDDR5 drives professional visual tasks and supports four Mini DisplayPort 1.4 outputs for multi-display setups. Eight DIMM slots allow memory expansion up to 512GB for larger datasets. Buyers who need redundant hot-swap power supplies should consider a different platform. Systems requiring integrated Wi-Fi or Bluetooth connectivity will need external adapters.

Single-Processor Xeon W-2135 Configuration

This unit supports a maximum of one physical CPU socket populated with the Xeon W-2135. The 465W chipset and included power supply do not offer redundant hot-swap capability. Storage uses a single 500GB NVMe M.2 drive with onboard RAID 0, 1, 5 and 10 support across six SATA 6.0 Gb/s channels. Two internal 3.5-inch bays and two external 5.25-inch bays provide room for additional drives.

Questions about this item

How do I install additional DDR4 ECC memory and which DIMM slots should I populate first?

Insert modules into the eight DDR4 slots following the four-channel sequence shown in the service guide; the common mistake is skipping a channel and leaving bandwidth unused.

What maintenance will the 500 GB NVMe drive and Quadro P1000 4 GB GDDR5 need over time?

The NVMe drive has no moving parts; monitor SMART health periodically. The Quadro P1000 fan and heatsink should be cleaned of dust annually to maintain thermal performance.

At what point does the 465 W power supply limit sustained loads on the Xeon W-2135 and Quadro P1000?

Continuous all-core CPU turbo plus full GPU compute can approach the 465 W ceiling, triggering throttling before either component reaches its own thermal limit.
