Precision 5820 Xeon workstation

The Dell Precision 5820 is a mid-tower workstation built for professional workloads. It ships with an Intel Xeon W-2135 six-core processor, 128GB of DDR4 ECC memory and a 1TB NVMe SSD. The Nvidia Quadro P5000 adds 16GB of GDDR5X video memory for certified ISV applications. Windows 11 Pro is pre-installed and activated.

Sustained-load thermal and power behaviour

A 950 watt 80 Plus Gold power supply rated at 90 percent efficiency feeds the CPU, GPU and memory under continuous load. The Xeon W-2135 runs at a 3.7GHz base frequency with a 4.5GHz turbo ceiling across its six cores. Registered ECC DDR4 2666 modules maintain data integrity during extended render or simulation jobs. The tower chassis provides airflow for the Quadro P5000 and system components.

128GB DDR4 ECC capacity ceiling

Four 32GB registered DIMMs populate half of the eight available slots, leaving four slots open for expansion to the 256GB maximum. Buyers who need more than 256GB of system memory must choose a different platform. The LGA 2066 socket and Xeon W-2135 define the memory controller limits for this configuration.

Questions about this item

How loud and hot does the 950 W 80 Plus Gold power supply run when the Xeon W-2135 and Quadro P5000 are under sustained load?

The 950 W 80 Plus Gold unit is rated at 90 % efficiency, so waste heat is kept low even when the 6-core Xeon hits 4.5 GHz turbo and the P5000 draws its full 16 GB GDDR5X frame buffer.

Which display cables or adapters must I already own to use the Quadro P5000's four DisplayPort outputs?

The card provides four native DisplayPort connectors, so you need DisplayPort cables or active DisplayPort-to-HDMI/DVI adapters for each monitor you plan to attach.

Will my existing DDR4 2666 ECC RDIMMs work alongside the four 32 GB modules already installed?

Yes, the board has eight DDR4 slots and supports up to 256 GB of registered ECC memory at 2666 MHz, so additional matched modules can be added without compatibility issues.
