Dell Precision 5820 Tower Workstation

The Dell Precision 5820 Tower Workstation is a new mid-tower desktop built around an Intel Xeon W-2135 processor running at 3.7 GHz with a 4.5 GHz turbo frequency across six cores. It ships with 128 GB of DDR4 2666 registered ECC memory installed in four of eight slots, a 500 GB PCIe NVMe solid-state drive and an Nvidia Quadro P4000 graphics card with 8 GB GDDR5 memory and four DisplayPort outputs. Windows 11 Pro is pre-installed and the system is powered by a 950 W 80 Plus Gold supply.

Suited for professional workloads.

This workstation suits engineers, designers and analysts who require ECC memory integrity, multi-display output from a certified professional GPU and a high-wattage power supply for sustained compute loads. Buyers who do not need error-correcting memory, who require consumer-grade graphics features or who need a smaller chassis should evaluate alternative platforms.

LGA 2066 socket with 256 GB DDR4 ceiling

The Intel Xeon W-2135 uses the LGA 2066 socket and the motherboard provides eight DDR4 slots with a maximum supported capacity of 256 GB, so the installed 128 GB can be doubled without replacing modules.

Questions about this item

How do I install the 128GB DDR4 2666MHz ECC memory into the eight slots without mixing registered and unbuffered modules?

The workstation ships with four 32GB registered ECC DDR4 2666 modules already seated; to expand toward the 256GB maximum add identical registered ECC sticks in the remaining slots, matching speed and rank configuration.

What maintenance will the 950W 80 Plus Gold power supply and Quadro P4000 8GB GDDR5 card need over time?

Clean dust from the PSU intake and GPU heatsink every six months; replace the PSU only if fan noise or voltage drift appears, and the GPU if driver support ends for your workload.

Which limit appears first during sustained all-core loads — the Xeon W-2135 thermal ceiling or the 950W PSU headroom?

The six-core Xeon W-2135 at 3.7GHz base with 4.5GHz turbo typically hits its thermal throttle point before the 950W Gold unit reaches its continuous output ceiling.
