Single-processor Xeon workstation

The HP Z4 G4 uses an Intel Xeon W-2225 running at 4.1 GHz with a 4.6 GHz turbo frequency across four cores. Sixteen gigabytes of DDR4 2933 ECC registered memory and a 500 GB NVMe drive provide fast, reliable throughput for large datasets. Windows 11 Pro 64-bit is pre-installed and digitally activated.

Sustained load behaviour

A 1000 W power supply rated at 90 percent efficiency delivers stable current during long renders or simulations. The Xeon processor and Quadro RTX 4000 share this headroom so clock speeds hold under continuous multi-threaded demand. ECC memory corrects single-bit errors without interrupting the workload.

Tool-less mid-tower chassis

The mid-tower frame opens without tools for memory, storage or card upgrades. Quadro RTX 4000 adds 8 GB GDDR6 on a 256-bit bus and drives up to four panels through three DisplayPort 1.4 connectors plus one USB-C port. Integrated gigabit Ethernet and high-definition audio handle networking and sound without extra cards.

Questions sur cet article

How loud does the 1000W 80 Plus Gold power supply run when the Xeon W-2225 hits 4.6GHz Turbo all day?

The 1000W 80 Plus Gold unit is rated 90% efficient, so it generates less waste heat and the fan stays at lower RPM under sustained 4.6GHz loads.

Which display cables do I need for the Quadro RTX 4000's 3x DP 1.4 and 1x USB-C ports?

The card provides three DisplayPort 1.4 outputs and one USB-C connector; bring matching DP or USB-C cables for each monitor you plan to attach.

Can my existing DDR4 2933 ECC modules fill the remaining slots up to the 512GB ceiling?

Yes, the board supports up to 512GB of DDR4 2933 ECC Registered memory, so compatible modules you already own can populate the free DIMM slots.
