Precision T5820 workstation for professional compute

The Dell Precision T5820 tower is built around an Intel Xeon W-2155 processor with 10 cores running at 3.3 GHz and a 4.5 GHz turbo frequency. It ships with 32 GB of DDR4 2666 registered ECC memory across four modules and a 2 TB PCIe NVMe solid-state drive. The Nvidia Quadro P4000 graphics card provides 8 GB of GDDR5 memory and four DisplayPort outputs for multi-monitor configurations. Windows 11 Pro 64-bit is pre-installed and digitally activated.

950 W 80 Plus Gold supply and quiet mid-tower

A Dell 950 watt 80 Plus Gold certified power supply operates at 90 percent efficiency, helping to keep power draw and heat output low during typical office workloads. The mid-tower chassis uses directed airflow to cool the Xeon CPU, Quadro GPU and memory without excessive fan noise. Integrated Realtek ALC3234 high-definition audio and an Intel i219 gigabit Ethernet controller add no moving parts, further reducing acoustic footprint in normal use.

Sustained load handling for rendering and simulation

Under continuous multi-threaded workloads such as 3D rendering or scientific simulation the 10-core Xeon maintains elevated frequencies while the Quadro P4000 sustains compute throughput across its 8 GB GDDR5 frame buffer. The 256-bit memory interface on the GPU and quad-channel DDR4 2666 system memory keep data flowing to all cores without throttling. The 950 watt Gold supply delivers stable power to both CPU and GPU rails throughout extended sessions.

Questions about this item

How do I install the 32GB DDR4 2666 memory into the eight slots, and which step do people get wrong?

The system ships with four 8 GB registered ECC modules already seated in the first four slots; add matching DDR4 2666 registered ECC DIMMs in the remaining slots in pairs, and the step most people miss is keeping the memory channels balanced so the Xeon W-2155 can use all channels.

What maintenance or replacement will the Nvidia Quadro P4000 with 8 GB GDDR5 need later?

Plan to clean the card's heatsink and fan annually, and be ready to swap the GPU if driver support for professional applications ends; the 950 W 80 Plus Gold supply has ample headroom for a similar-power replacement.

What limit shows up first when the Xeon W-2155 runs at 4.5 GHz turbo under sustained load?

The 950 W 80 Plus Gold power supply and the tower's thermal design set the practical ceiling; the CPU will throttle before the 256 GB memory ceiling or the 2 TB NVMe drive become bottlenecks.
