Precision T5820 Xeon W-2145 workstation

The Dell Precision T5820 is a mid-tower workstation built around an Intel Xeon W-2145 8-core processor running at 3.7GHz with a 4.5GHz turbo frequency. It ships with 256GB of DDR4 2666MHz registered ECC memory installed across eight slots, reaching the platform maximum. A 500GB NVMe SSD provides the boot volume, while an Nvidia Quadro P2000 graphics card with 5GB GDDR5 drives up to four DisplayPort outputs. Windows 11 Pro is pre-installed and digitally activated.

Suited for memory-intensive professional workloads

This system suits engineers, analysts and content creators who need a large ECC memory footprint and certified professional graphics for CAD, simulation or multi-display visualisation. The 950W 80 Plus Gold power supply supports the installed components with headroom. Buyers who need more than 256GB of system memory cannot expand beyond the factory limit. Users requiring additional internal NVMe storage will find the single M.2 slot already occupied by the boot drive.

256GB DDR4 2666MHz registered ECC maximum

The critical specification is the 256GB DDR4 2666MHz registered ECC memory ceiling, which is already fully populated with eight 32GB modules. Any future memory change requires replacing the existing kit rather than adding modules, and replacement kits must match the registered ECC type and 2666MHz speed to maintain stability and error correction. This constraint defines whether the workstation can support a given dataset size or virtualisation density.

Questions about this item

What clearance and power connections does the 950 W 80 Plus Gold PSU need in a mid-tower case?

The 950 W 80 Plus Gold unit fits the Precision T5820 mid-tower chassis and uses standard ATX power connectors; ensure the case allows at least 160 mm depth for the PSU and has a 24-pin motherboard plus 8-pin CPU power cables.

How are the eight 32 GB DDR4 2666 ECC modules seated, and which slot order avoids a no-post condition?

Populate the eight DIMM slots in matched pairs starting with the sockets nearest the Xeon W-2145 (LGA 2066) socket; the system requires registered ECC DDR4 2666 and will not boot if modules are mixed across channels.

When should the 500 GB M.2 NVMe drive be replaced, and what capacity limit applies?

Replace the M.2 NVMe SSD when SMART health drops below 90 % or write endurance is exhausted; the platform supports up to 256 GB per module, so any single replacement drive must not exceed that limit.
