Intel Xeon W-2235 six-core workstation

The HP Z4 G4 is a mid-tower workstation built around an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo frequency across six cores. It ships with 16 GB of DDR4 2933 ECC registered memory in a two-by-eight configuration and a 500 GB PCIe NVMe solid-state drive. Windows 11 Pro 64-bit is pre-installed for immediate deployment in professional environments.

Sustained compute with 1000 W Gold supply

A 1000 W 80 Plus Gold power supply rated at 90 percent efficiency delivers stable power during extended render or simulation sessions. The Xeon W-2235 maintains elevated clocks across all six cores without throttling, supported by the chassis thermal design. ECC memory corrects single-bit errors in real time, preserving data integrity throughout long-running workloads.

Quadro P4000 8 GB GDDR5 display limits

The NVIDIA Quadro P4000 provides 8 GB of GDDR5 memory on a 256-bit bus and four DisplayPort 1.4 outputs for multi-monitor setups. PCIe Gen 3 bandwidth and the 256-bit memory interface define the practical ceiling for GPU-accelerated throughput. System memory tops out at 512 GB DDR4 2933 on this platform, capping total addressable capacity for in-core datasets.

Questions about this item

How loud and hot does the 1000W 80 Plus Gold power supply run during all-day workloads?

The 1000W 80 Plus Gold unit delivers 90% efficiency, reducing waste heat and fan noise during sustained loads.

Which display cables must I already own to use the Quadro P4000 8GB graphics card?

The card provides four DisplayPort 1.4 outputs, so you need DP 1.4 cables or active adapters for HDMI/DVI monitors.

Can I keep my existing DDR4 2933 ECC registered modules when expanding memory to 512GB?

Yes, the four DIMM slots support DDR4 2933 ECC registered memory up to 512GB total, so current modules remain compatible.
