Precision 5820 Tower Workstation

The Dell Precision 5820 Tower is a mid-tower workstation built around an Intel Xeon W-2145 eight-core processor running at 3.7 GHz with 4.5 GHz turbo. It ships with 256 GB of DDR4 2666 MHz registered ECC memory across eight slots, a 500 GB NVMe SSD and an Nvidia Quadro P5000 graphics card with 16 GB GDDR5X memory. Windows 11 Pro is pre-installed.

Upgrade from older Xeon towers

This system replaces earlier single-socket workstations that max out at lower core counts or slower memory speeds. The jump is worth it when applications demand 256 GB of ECC memory, a 256-bit GPU with four DisplayPort outputs and a 950 W 80 Plus Gold power supply for sustained loads. Buyers who need multiple GPUs or more internal drive bays should look elsewhere.

Standard mid-tower installation

The workstation uses a conventional mid-tower chassis with tool-less access to memory slots and the M.2 NVMe drive. The 950 W supply uses standard ATX connectors and the Quadro P5000 occupies a dual-slot PCIe x16 lane. Common issues include forgetting to seat all eight DIMMs for full quad-channel bandwidth and overlooking the GPU auxiliary power cable.

Questions about this item

What clearance and power connectors does the 256-bit Quadro P5000 need inside the mid-tower chassis?

The card occupies a full-length, dual-slot PCIe x16 slot and draws auxiliary power through one 8-pin and one 6-pin connector from the 950 W 80 Plus Gold supply.

In which sequence should the eight registered ECC DDR4 2666 modules be seated to avoid a no-post condition?

Populate the eight slots in the order marked on the motherboard — typically CPU1 channels first, then CPU2 — ensuring each 32 GB DIMM clicks fully home before applying power.

When the 500 GB M.2 NVMe drive reaches its write-endurance limit, what replacement specification matches the original?

Swap in another M.2 2280 PCIe NVMe SSD of equal or greater capacity; the platform supports standard NVMe drives without proprietary firmware.
