HP Inc 805L7UT#ABA Z4 G5 Tower Workstation
Overview
The HP Z4 G5 (805L7UT#ABA) is a tower workstation configured with an Intel Xeon W w3-2435 processor — 8 cores, 16 threads, 3.1 GHz base with boost to 4.3 GHz, and a 22.5 MB L3 cache. At 165 W TDP (198 W max turbo), it draws serious power in exchange for sustained multi-threaded throughput, making it a practical compute host for surveillance workstations running high-channel VMS software, AI-accelerated video analytics, or forensic video review. The unit ships with 16 GB DDR5-SDRAM in a single DIMM, leaving 7 slots open across 8 total DIMM sockets — so you can expand to 512 GB maximum without replacing existing memory. The 512 GB M.2 PCIe NVMe 2280 TLC drive delivers fast sequential reads for smooth multi-stream playback without the latency penalty of SATA storage. At 23.2 lb and 22.20 × 12.40 × 22.50 in, this is a full-tower chassis — plan rack or floor space accordingly, not a 1U shelf.
Compatibility
The Z4 G5 platform accepts standard DDR5 ECC RDIMMs, making memory upgrades straightforward through HP-qualified modules. The M.2 2280 slot uses PCIe NVMe — additional storage expansion requires compatible PCIe NVMe or SATA drives in the available internal bays. As a workstation-class system, it pairs with enterprise network video recorders and VMS platforms (Milestone XProtect, Genetec Security Center, Axis Camera Station) running as server-mode clients, and with PoE network switches in the same rack when deployed as a local VMS host. The Xeon W3-2435's 8-core architecture supports hardware-accelerated decoding on compatible GPU add-in cards installed into the PCIe expansion slots. Consult the HP workstation lineup for alternative configurations if your channel count or analytics load demands more cores or higher memory bandwidth.
Installation Notes
Base memory is a single 16 GB DDR5 DIMM — populate additional slots in matched pairs starting from slot 1 to maximize memory channel bandwidth for high-stream workloads. The processor TDP of 165 W base and 198 W turbo requires adequate rack or room ventilation; do not enclose in a sealed cabinet without active airflow. Unit weighs 23.2 lb — two-person lift recommended for rack positioning. Country of origin: Mexico.
