Professional Workstation Ready

This HP Z4 G4 tower workstation arrives new with an Intel Xeon W-2135 six-core processor at 3.7 GHz and 64 GB of DDR4 ECC memory. It targets engineers, designers and data analysts who need reliable performance for CAD, rendering and large dataset tasks. Windows 11 is preinstalled for immediate deployment.

Quadro P1000 And Fast Storage

The NVIDIA Quadro P1000 with 4 GB GDDR5 drives professional visual applications and supports four Mini DisplayPort 1.4 outputs for multi-display setups. A 1 TB NVMe SSD provides rapid access to projects while a 2 TB 7.2K SATA drive adds bulk capacity. Onboard RAID 0/1/5/10 handles redundancy or speed without extra hardware.

Tower Chassis With Expansion Room

The tower frame includes two internal 3.5-inch bays with acoustic dampening rails, two external 5.25-inch bays and a dedicated 9.5 mm optical bay housing a DVD+/-RW drive. Connectivity covers dual LAN ports, USB 2.0, USB 3.1 Gen 1 and optional Thunderbolt 3. Two PCIe x16 Gen 3 slots allow a second graphics card if the 750 W supply covers the load. Buyers needing more than 64 GB RAM or hot-swap power supplies should look elsewhere.

Questions about this item

How many DDR4 ECC memory slots are free for future upgrades?

All eight DIMM slots are occupied by the installed 64 GB, so adding memory later requires replacing existing modules.

What limits sustained CPU performance before thermal throttling?

The single 750 W power supply and tower air cooling set the practical ceiling for continuous all-core loads on the Xeon W-2135.

How loud is the workstation when the Quadro P1000 and Xeon run flat-out all day?

Acoustic-dampening rails on the 3.5-inch bays and the standard tower fan profile keep noise at typical workstation levels under full load.
