Precision T5820 Xeon workstation

The Dell Precision T5820 Tower is a mid-tower workstation built around an Intel Xeon W-2255 processor with 10 cores running at 3.70 GHz base and 4.7 GHz turbo. It ships with 64 GB of DDR4 2933 MHz registered ECC memory across four slots, a 500 GB NVMe SSD, and an NVIDIA Quadro P5000 graphics card with 16 GB GDDR5X memory. Windows 11 Pro is pre-installed for professional workloads.

Sustained load behaviour

The 950 W 80 Plus Gold power supply delivers 90 % efficiency to support continuous operation of the 10-core Xeon and Quadro P5000 under prolonged render or compute tasks. Registered ECC DDR4 memory corrects single-bit errors in real time, maintaining data integrity during extended simulation or analysis runs. The tower form factor provides airflow for the CPU and GPU to maintain stable clocks over long sessions.

Interface and expansion limits

The LGA 2066 platform offers eight DDR4 slots with a 256 GB maximum memory ceiling, leaving four slots open for future upgrades. The Quadro P5000 provides four DisplayPort outputs for multi-monitor configurations. A single M.2 NVMe slot is occupied by the 500 GB boot drive, while additional storage must use 2.5-inch or 3.5-inch bays. Gigabit Ethernet via the Intel i219 controller handles wired network connectivity.

Questions about this item

How loud or hot does the 950 W 80 Plus Gold power supply run under sustained load?

The 950 W 80 Plus Gold unit is rated for 90% efficiency, so less energy becomes heat and fan speeds stay lower during long workloads.

Which display cables or adapters do I need to connect monitors to the Quadro P5000?

The card provides four DisplayPort outputs; you will need DisplayPort cables or active DisplayPort-to-HDMI/DVI adapters for each screen.

Will my existing DDR4 2666 MHz ECC modules work alongside the installed 2933 MHz memory?

Yes — the board supports up to 256 GB across eight slots and will clock all modules to the lowest common speed, so 2666 MHz sticks run without issues.
