Precision 5820 Xeon workstation

This Dell Precision 5820 tower workstation is built for professionals who need reliable compute power for engineering simulations, 3D rendering and data analysis. It ships with a 6-core Intel Xeon W-2135 processor running at 3.70GHz with 4.5GHz turbo, 128GB of DDR4 2666 registered ECC memory and a 2TB PCIe NVMe solid-state drive. The Nvidia Quadro P5000 graphics card provides 16GB of GDDR5X memory and four DisplayPort outputs for multi-monitor setups. Windows 11 Pro is pre-installed and digitally activated.

Upgrading from consumer desktops

Moving to this platform makes sense when workloads exceed the memory capacity or error-correction guarantees of standard desktop boards. The LGA 2066 socket and eight DIMM slots support up to 256GB of DDR4 2666 registered ECC memory, so the jump is worth it for users who hit 128GB limits or need ECC protection for long compute runs. The 950W 80 Plus Gold power supply delivers 90% efficiency to sustain heavy CPU and GPU loads without throttling. Buyers who need more than 2TB of high-speed storage or a second graphics card should look elsewhere.

Build integration

The mid-tower chassis houses the 950W power supply, Intel i219 Gigabit Ethernet controller and Realtek ALC3234 high-definition audio on the motherboard. Four DisplayPort connectors on the Quadro P5000 free up PCIe slots that would otherwise be needed for additional video outputs. The 2TB M.2 NVMe drive occupies one M.2 slot, leaving the remaining drive bays and PCIe slots available for expansion cards or extra storage. No monitor is included, so an external display must be provided.

Questions about this item

Will the 950 W 80 Plus Gold power supply fit the mid-tower chassis and provide the connectors needed for the Quadro P5000?

Yes — the 950 W 80 Plus Gold unit is the standard supply for the Precision 5820 mid-tower and includes the PCIe power connectors required by the Quadro P5000.

Which memory slots should I populate first when adding DDR4 2666 registered ECC modules to the eight-slot motherboard?

Install modules in the four slots associated with CPU0 (usually labelled DIMM A1, B1, C1, D1) before using the remaining four slots for CPU1.

When the 2 TB M.2 NVMe drive reaches its write endurance limit, what replacement drive format does the motherboard accept?

The board accepts another M.2 PCIe NVMe SSD; the existing 2 TB drive uses that interface and form factor.
