Precision 5820 Tower Workstation

The Dell Precision 5820 Tower is a mid-tower desktop built for professional workloads. It ships with an Intel Xeon W-2245 eight-core processor, 128GB of DDR4 2933MHz registered ECC memory, a 1TB PCIe NVMe solid-state drive and an Nvidia Quadro P4000 graphics card with 8GB GDDR5 memory. Windows 11 Pro is pre-installed.

Thermals noise and power

A 950-watt 80 Plus Gold certified power supply rated at 90% efficiency delivers power to the components. The tower chassis uses internal airflow paths to cool the Xeon processor and Quadro P4000 card under sustained load. Integrated Realtek ALC3234 high-definition audio and Intel i219 Gigabit Ethernet are onboard.

128GB DDR4 2933MHz ECC memory

Four 32GB registered ECC DDR4 modules populate four of the eight available slots, leaving room to expand to the 256GB maximum supported capacity. Buyers who need more memory bandwidth or capacity than 128GB provides should verify the 256GB ceiling before purchase.

Questions about this item

How do I install the 128GB DDR4 2933MHz Registered ECC memory in the 8 available slots, and what common mistake should I avoid?

Populate the eight DDR4 slots with the four 32GB modules in the channel order shown on the motherboard diagram; the step often missed is ensuring each module clicks fully into its latch so the registered ECC timing trains correctly at 2933MHz.

Which component in the Precision 5820 will most likely need replacement first under heavy daily workloads?

The 950W 80 Plus Gold power supply is the primary wear item; its capacitors age with sustained 90% efficiency loads, so plan a swap after several years of continuous high-draw compute tasks.

What thermal or power limit appears first when the Xeon W-2245 runs at 4.7GHz turbo across all eight cores for extended periods?

The 950W Gold-rated PSU and the tower’s air-cooling envelope cap sustained all-core turbo; the CPU will throttle once package power approaches the supply’s continuous delivery ceiling.
