Precision T5820 Workstation Xeon W-2255

The Dell Precision T5820 is a tower workstation built around a 10-core Intel Xeon W-2255 processor running at 3.70GHz. It ships with 32GB of DDR4 memory and a 3TB hard drive for local storage. Windows 11 Pro is pre-installed and a dedicated K620 graphics card handles display output.

Suits CAD design and data-heavy tasks.

This configuration targets professional workloads such as design, content creation, engineering and data-heavy applications where CPU core count and memory capacity matter. The single K620 card limits 3D performance, so buyers who need high-end GPU rendering or multi-card compute should look at different hardware.

10-core Xeon W-2255 at 3.70GHz defines the compute

The processor delivers ten cores at a 3.70GHz base frequency, setting the performance ceiling for parallel workloads and single-thread responsiveness. Memory can be expanded to 128GB DDR4 across available slots, while two 3.5-inch bays and two M.2 slots provide internal storage flexibility.

Questions about this item

How do I install the Xeon W-2255 processor and what step is commonly missed?

Align the notches on the processor with the socket keys, lower it gently, and secure the retention lever. The step often missed is applying fresh thermal paste before mounting the cooler.

What maintenance will the 32GB DDR4 memory need later?

DDR4 modules are solid-state and require no scheduled replacement. If capacity becomes limiting, the board supports up to 128GB using compatible DDR4 DIMMs.

At what point does the 3.70GHz 10-core CPU hit its sustained-use limit?

Under continuous full-core load the processor will reach its thermal design power ceiling, causing the firmware to throttle clocks until temperatures drop.
