Professional workstation for CAD

The HP Z4 G4 tower workstation ships with an Intel Xeon W-2135 six-core processor running at 3.7 GHz and 128 GB of DDR4 ECC memory across eight DIMM slots. An NVIDIA Quadro P1000 with 4 GB GDDR5 provides four Mini DisplayPort 1.4 outputs for multi-display professional visual work. Windows 11 is preinstalled.

Check your memory and expansion needs before

The system arrives at its maximum supported memory capacity of 128 GB using all eight DDR4 slots, so no further RAM upgrades are possible without replacing modules. Storage expansion relies on two internal 3.5-inch bays with acoustic rails, two external 5.25-inch bays and a dedicated 9.5 mm optical bay. The onboard SATA controller supports RAID 0, 1, 5 and 10 across six channels.

Fits a professional tower build

The 465 W power supply powers the installed Quadro P1000 and leaves room for a second PCI Express x16 Gen 3 graphics card, though additional power connections depend on the supply option chosen. Connectivity includes two LAN ports, USB 2.0, USB 3.1 Gen 1 and optional USB 3.1 Gen 2 plus Thunderbolt 3. A DVD+/-RW drive occupies the slim optical bay.

商品問答

What comes in the box with the Z4 G4 and which parts must be bought separately?

The tower arrives with the Xeon W-2135 processor, 128 GB DDR4 ECC memory filling all 8 slots, a 250 GB NVMe M.2 SSD, Quadro P1000 4 GB GDDR5 graphics card, DVD±RW drive, two LAN ports and Windows 11 pre-installed. Extra storage drives, additional GPUs, USB 3.1 G2 or Thunderbolt 3 cards are not included.

Which memory configuration should I choose when the system already shows 128 GB DDR4?

The workstation is populated to its 128 GB maximum across 8 DIMM slots running four-channel 2666 MHz ECC DDR4. No further memory can be added without removing existing modules, so the listed capacity is the only option.

How does the 3.7 GHz Xeon W-2135 perform inside this workstation for CAD and rendering?

The six-core 3.7 GHz Xeon W-2135 with 12 threads delivers strong single-thread speed for CAD modelling and enough multi-thread throughput for moderate rendering, backed by 128 GB ECC memory and Quadro P1000 4 GB GDDR5 for certified driver stability.
