DELL Precision 5820 Tower Workstation Xeon W-2235 3.8GHz 256GB DDR4 1TB NVMe Quadro P600 Windows 11 Pro

Precision 5820 workstation for professional compute

The Dell Precision 5820 Tower is a mid-tower desktop built around an Intel Xeon W-2235 processor running at 3.8 GHz with a 4.6 GHz turbo frequency and six cores. It ships with 256 GB of DDR4 2933 registered ECC memory across eight slots and a 1 TB PCIe NVMe solid-state drive. An NVIDIA Quadro P600 graphics card with 2 GB GDDR5 and four DisplayPort outputs drives multiple displays for engineering and design workloads.

LGA 2066 platform limits and memory ceiling

The LGA 2066 socket and Xeon W-2235 combination caps supported memory at 256 GB, which this unit already reaches with its eight 32 GB modules. DDR4 2933 is the rated speed; faster modules will downclock to this frequency. The 950 W 80 Plus Gold power supply delivers 90 percent efficiency but does not expose auxiliary connectors beyond the factory configuration, limiting future GPU upgrades to cards within the same power envelope.

Replaces older tower workstations needing ECC

This system upgrades environments still running earlier Precision towers that max out at lower memory capacities or lack native quadruple DisplayPort output. The jump is worthwhile when applications require registered ECC memory at full 256 GB capacity and four simultaneous professional displays. It is not suited for buyers who need more than 256 GB of RAM, additional internal drive bays beyond the single M.2 slot, or graphics performance beyond the Quadro P600 class.
