Precision T5820 Xeon workstation

This Dell Precision T5820 tower workstation ships new with Windows 11 Pro. It runs an Intel Xeon W-2125 4.0GHz quad-core processor with 4.5GHz turbo, 256GB DDR4 2666MHz registered ECC memory across eight slots, a 500GB M.2 NVMe SSD and an Nvidia Quadro P4000 8GB GDDR5 graphics card with four DisplayPort outputs. A 950W 80 Plus Gold power supply drives the mid-tower chassis.

Suits memory-heavy ISV workloads

The 256GB DDR4 capacity and Xeon ECC platform suit engineers running large simulations, rendering pipelines or multi-VM test beds that need maximum registered memory on a single-socket LGA 2066 system. Buyers who need more than 256GB system memory, more than 8GB GPU frame buffer or a newer processor architecture should evaluate other platforms.

256GB DDR4 2666 registered ECC limit

The motherboard tops out at 256GB across eight DDR4 2666 registered ECC DIMM slots, so this configuration already sits at the hard memory ceiling. Verify that your application licences and dataset sizes fit within this 256GB bound before purchase.

Questions about this item

How do I install the DDR4 memory modules in the Precision T5820 and which step is commonly missed?

Populate all eight slots with the 32 GB registered ECC DDR4 2666 modules; the step often missed is ensuring each module clicks fully into its notch so the system recognises the full 256 GB capacity.

What maintenance or replacement will the Quadro P4000 graphics card need later?

The Quadro P4000 uses 8 GB GDDR5 memory soldered to the board, so no memory upgrade is possible; plan to replace the entire card when workload demands exceed its 256-bit memory interface.

What limit appears first when the Xeon W-2125 runs at 4.5 GHz turbo under sustained load?

The 950 W 80 Plus Gold power supply and the mid-tower thermal design set the practical ceiling; the CPU will throttle from 4.5 GHz turbo once the cooling solution saturates.
