Precision T5820 Xeon workstation

The Dell Precision T5820 tower is built for professional workloads that demand high core counts and large memory capacity. It ships with a 10-core Intel Xeon W-2155 processor running at 3.3 GHz with a 4.5 GHz turbo frequency. The system includes 256 GB of DDR4 2666 registered ECC memory across eight slots. A 2 TB NVMe SSD and Nvidia Quadro P4000 graphics card with 8 GB GDDR5 complete the core specification.

Mid-tower installation and ECC memory

The mid-tower chassis provides standard access to the eight DDR4 slots and the M.2 NVMe drive bay. Installing the registered ECC modules requires matching the 256 GB maximum capacity exactly as populated. The 950 W 80 Plus Gold power supply uses proprietary Dell connectors, so swapping it for a standard ATX unit is not straightforward. The Quadro P4000 occupies a double-width slot and connects via four DisplayPort outputs.

Sustained load with 950 W Gold supply

Under continuous multi-threaded workloads the Xeon W-2155 maintains elevated frequencies within the 950 W power envelope. The 80 Plus Gold rated supply delivers 90 percent efficiency at typical loads, limiting waste heat inside the chassis. The Quadro P4000 256-bit memory interface sustains compute and display output across four heads without throttling. Windows 11 Pro 64-bit manages the 256 GB memory space for extended rendering or simulation tasks.

Questions about this item

How do I verify the Xeon W-2155 reaches its 4.5 GHz turbo speed under load?

Open Task Manager or a hardware monitor and watch the CPU frequency climb toward 4.5 GHz while running a multi-threaded workload; the 10-core processor should sustain elevated clocks with the 950 W 80 Plus Gold supply.

What ships inside the box and which common peripherals are absent?

The tower arrives with the Xeon W-2155, 256 GB DDR4 ECC memory (eight 32 GB modules), 2 TB NVMe SSD, Quadro P4000 with four DisplayPort outputs, Windows 11 Pro licence and 950 W power supply; no monitor, keyboard or mouse are included.

Which memory configuration matches the factory 256 GB limit?

The system is already populated with eight 32 GB DDR4 2666 MHz registered ECC DIMMs, filling every slot and reaching the 256 GB maximum supported by the platform.
