DELL Precision 5820 Tower Workstation Xeon W-2155 10 Core 128GB DDR4 500GB NVMe Quadro P4000

Dell Precision 5820 Tower Workstation

The Dell Precision 5820 is a mid-tower desktop workstation built for professional workloads. It runs Windows 11 Pro on an Intel Xeon W-2155 processor with ten cores at 3.3GHz and a 4.5GHz turbo frequency. The system includes 128GB of DDR4 2666 registered ECC memory across eight slots and a 500GB NVMe SSD. An Nvidia Quadro P4000 with 8GB GDDR5 provides four DisplayPort outputs. A 950W 80 Plus Gold power supply rated at 90 percent efficiency powers the chassis.

Who this suits and who should look elsewhere

This workstation suits engineers, designers and analysts who need certified drivers and ECC memory for CAD, simulation or rendering tasks. The ten-core Xeon and Quadro P4000 combination handles multi-threaded applications and professional 3D viewports reliably. Buyers who want more storage capacity than a single 500GB NVMe drive should consider additional drives. Users requiring higher GPU memory or newer architecture for advanced compute workloads should evaluate other configurations.

Deciding specification: 128GB DDR4 2666 registered

The 128GB DDR4 2666 registered ECC configuration fills four of eight slots and supports up to 256GB total capacity. Registered ECC modules are required for stability in memory-intensive professional applications. Confirm your workload benefits from ECC before purchasing, as standard unbuffered DDR4 will not function in this platform. The memory speed and registered design are fixed by the workstation architecture.
