Precision 5820 Workstation

The Dell Precision 5820 Tower is a mid-tower workstation built for professional workloads. It ships new with Windows 11 Pro and integrates a 10-core Intel Xeon W-2155 processor running at 3.30 GHz with a 4.5 GHz turbo frequency.

Suited for memory-heavy tasks; not for lighter needs

This system suits users who need the full 256 GB of DDR4 2666 MHz registered ECC memory across eight slots. Buyers whose applications run comfortably on lower memory capacities or non-ECC modules should consider a different configuration.

2 TB NVMe boot drive

A single 2 TB PCIe NVMe solid-state drive provides the primary storage. The specifications list no hard-disk drive, so anyone requiring additional bulk storage must add it separately.

Questions about this item

How do I install the 256GB DDR4 2666 ECC memory kit into the eight slots?

Power off the system, open the mid-tower chassis, and populate all eight DIMM slots with the 32GB registered ECC modules; the step often missed is seating each module until both retention clips click fully.

What maintenance or replacement will the 950W 80 Plus Gold power supply need later?

The 950W unit has no user-serviceable parts; plan to replace the entire PSU if fan noise increases or voltages drift after several years of continuous workstation loads.

Which limit appears first during sustained heavy rendering on the Quadro P5000 16GB GDDR5X?

The 256-bit memory bus and 16GB frame buffer saturate before the Xeon W-2155 cores, so texture-heavy scenes hit VRAM capacity first.
