Professional workstation tower

The Dell Precision T5820 is a mid-tower desktop built around an Intel Xeon W-2135 six-core processor running at 3.7 GHz with a 4.5 GHz turbo frequency. It ships with 256 GB of DDR4 2666 MHz registered ECC memory across eight slots and a 500 GB NVMe SSD. Windows 11 Pro is pre-installed for immediate deployment.

Quadro P5000 graphics and 950 W power

An Nvidia Quadro P5000 with 16 GB GDDR5X memory and four DisplayPort outputs drives multi-monitor setups for visualisation workloads. The 950 W 80 Plus Gold certified supply delivers 90 % efficiency to support the GPU and fully populated memory configuration. Integrated Intel i219 gigabit Ethernet and Realtek ALC3234 audio handle connectivity without add-in cards.

256 GB registered ECC memory ceiling

The platform supports a maximum of 256 GB across its eight DDR4 slots, so this unit already sits at the memory limit. Buyers who need more capacity must choose a different workstation class. The LGA 2066 socket and mid-tower chassis define the upgrade boundary for processors and internal cards.

Questions about this item

Will the 256 GB DDR4 memory need expansion later?

All eight DIMM slots are filled with 32 GB registered ECC modules, so any future increase would require replacing existing sticks rather than adding to empty slots.

What caps sustained performance on the Xeon W-2135?

The six-core Xeon W-2135 reaches 4.5 GHz turbo, but extended all-core workloads will settle at lower clocks once the CPU hits its thermal ceiling inside the mid-tower chassis.

How loud and hot does the 950 W 80 Plus Gold PSU run under full load?

The Gold-rated 950 watt supply operates at 90 % efficiency, so waste heat and fan noise stay modest even when the Quadro P5000 and Xeon draw maximum power for hours.
