Precision T5820 Xeon workstation

The Dell Precision T5820 is a mid-tower workstation built around a 10-core Intel Xeon W-2155 processor running at 3.3 GHz with a 4.5 GHz turbo. It ships with 64 GB of DDR4 2666 registered ECC memory across four slots and a 500 GB NVMe SSD. An Nvidia Quadro P4000 with 8 GB GDDR5 drives up to four displays. Windows 11 Pro is pre-installed.

DDR4 2666 registered ECC ceiling

Memory runs at 2666 MT/s in a quad-channel arrangement and the board provides eight DIMM sockets. The platform supports up to 256 GB of registered ECC DDR4, so the installed 64 GB leaves headroom for expansion. Only registered ECC modules are compatible; unbuffered or non-ECC DDR4 will not function in this system.

Single-thread turbo frequency

The Xeon W-2155 reaches 4.5 GHz on a single core, which governs responsiveness in lightly threaded CAD and simulation tasks. Multi-core workloads settle at the 3.3 GHz base clock across all ten cores. Buyers whose primary bottleneck is sustained all-core throughput should evaluate whether the base frequency meets their queue-time targets.

Questions about this item

Should I pick the 64 GB DDR4 configuration or look for a higher capacity?

The system ships with 64 GB DDR4 2666 MHz registered ECC memory in four 16 GB modules and supports up to 256 GB across eight slots, so you can add more later if your workloads demand it.

What does the Xeon W-2155 3.3 GHz base and 4.5 GHz turbo mean for real workloads?

The 10 core processor runs at 3.3 GHz base clock and can boost to 4.5 GHz on active cores, giving strong single-thread speed for CAD and simulation while all cores sustain high throughput for rendering.

How does the PCIe NVMe drive and Quadro P4000 interface affect performance limits?

The 500 GB M.2 NVMe SSD connects via PCIe for fast boot and project loading, while the Quadro P4000 uses a PCIe x16 slot with 8 GB GDDR5 and four DisplayPort outputs for multi-monitor professional graphics.
