Precision T5820 Tower Workstation

This Dell Precision T5820 tower workstation is built for professionals who need sustained multi-core throughput and large memory capacity. It ships with an Intel Xeon W-2135 six-core processor, 256GB of DDR4 2666MHz registered ECC memory, a 1TB NVMe SSD and an Nvidia Quadro P2000 graphics card with 5GB GDDR5. Windows 11 Pro is pre-installed and activated.

Upgrading from limited memory

The jump is worth it when workloads exceed 64GB of RAM or require ECC protection for data integrity. The eight DIMM slots are fully populated with 32GB modules, reaching the platform maximum of 256GB. The Xeon W-2135 provides a 3.7GHz base clock with 4.5GHz turbo across six cores, replacing systems that bottleneck on core count or memory bandwidth.

Sustained load behaviour with 950W Gold power

A 950 watt 80 Plus Gold certified power supply delivers 90% efficiency to support continuous CPU and GPU utilisation. The Quadro P2000 drives up to four displays via DisplayPort while the Intel i219 gigabit controller handles network traffic. Integrated Realtek ALC3234 audio completes the workstation I/O without adding discrete cards that increase power draw.

Questions about this item

What internal space and power does the 950 W power supply need to fit in the mid-tower chassis?

The mid-tower chassis houses the 950 W 80 Plus Gold power supply as standard; it occupies the dedicated PSU bay at the rear and connects to the motherboard and graphics card with the factory cables.

How is the Nvidia Quadro P2000 installed and what step is often missed?

The card is factory-fitted in a full-height PCIe x16 slot and its 5 GB GDDR5 frame buffer drives four DisplayPort outputs; the step often missed is connecting the monitor cables to the card instead of the motherboard video ports.

What memory maintenance or expansion will the 256 GB DDR4 configuration require later?

All eight DDR4 slots are filled with 32 GB registered ECC modules running at 2666 MHz; any future increase would mean replacing modules rather than adding, and ECC memory should be matched by spec when swapped.
