Precision 7920 dual-Xeon workstation

The Dell Precision 7920 tower ships new with two Intel Xeon Gold 5122 processors running at 3.6 GHz, giving 8 physical cores and 16 threads via hyper-threading. It is built for engineers and designers who run certified AutoCAD workloads on Windows 11 Pro. The 1400 W power supply supports the dual-CPU configuration and the AMD Radeon Pro WX 7100 8 GB GDDR5 graphics card.

Installation notes

The system arrives assembled; the 250 GB NVMe M.2 SSD is already mounted on its PCIe adapter card. Memory uses DDR4-2666 ECC modules across 24 DIMM slots, so any future upgrades must match that exact specification. The DVD±RW drive occupies a standard 5.25-inch bay. No operating-system installation is required.

Memory capacity limit

The board supports a maximum of 1536 GB of DDR4-2666 ECC memory with both CPUs installed, so this unit is already at the architectural ceiling. Buyers who need more RAM cannot expand this chassis further. The single 250 GB NVMe drive also means users requiring large local datasets must add secondary storage themselves.

Questions about this item

How can I verify the dual Xeon Gold 5122 CPUs are running at 3.6 GHz with 16 threads after setup?

Open Task Manager and check the Performance tab — it should show 16 logical processors at a base speed of 3.6 GHz.

What components are included in the box and what must be purchased separately?

The tower includes two Xeon Gold 5122 CPUs, 1536 GB DDR4-2666 ECC memory, 250 GB NVMe M.2 SSD on a PCIe adapter, Radeon Pro WX 7100 8 GB GDDR5, DVD±RW drive, 1400 W power supply and Windows 11 Pro; a monitor is not included.

Which memory configuration should I choose if I want the full 1536 GB capacity supported by this workstation?

This unit already ships with the maximum 1536 GB of DDR4-2666 ECC memory across the 24 DIMM slots, so no further capacity upgrade is possible.
