DELL Precision T5820 desktop PC Xeon W-2135 3.7GHz 256GB DDR4 2TB NVMe Quadro P5000 16GB

Precision T5820 workstation with 256 GB DDR4

This Dell Precision T5820 tower workstation ships new with an Intel Xeon W-2135 six‑core processor running at 3.7 GHz with a 4.5 GHz turbo frequency. It is equipped with 256 GB of DDR4 2666 MHz registered ECC memory across eight slots, a 2 TB PCIe NVMe solid‑state drive, and an Nvidia Quadro P5000 graphics card with 16 GB GDDR5X memory and four DisplayPort outputs. Windows 11 Pro is pre‑installed and the unit includes a 950 W 80 Plus Gold power supply.

Suited for memory‑intensive professional workloads

The 256 GB memory capacity and ECC support make this system appropriate for large‑dataset analysis, simulation, rendering and virtualisation tasks that require maximum registered DIMM population. Buyers who need ECC memory beyond the 256 GB ceiling supported by this platform should consider a different workstation class. Users without a requirement for registered ECC memory or quad‑DisplayPort professional graphics may find a smaller configuration more cost‑effective.

256 GB DDR4 2666 registered ECC memory limit

The motherboard provides eight DIMM slots and the processor’s memory controller supports a maximum of 256 GB of DDR4 2666 registered ECC memory. This ceiling is fixed by the Xeon W-2135 and the platform chipset, so the installed 8 x 32 GB configuration already reaches the highest capacity this workstation can accept. Any upgrade plan that assumes higher memory capacity is incompatible with this hardware.
