Dual Xeon Gold 5122 Workstation

The Dell Precision 7920 tower combines two Intel Xeon Gold 5122 processors running at 3.6 GHz with 768 GB of DDR4-2666 ECC memory. A 250 GB NVMe M.2 SSD on a PCIe adapter card provides the boot volume. The Nvidia Quadro M5000 graphics card supplies 8 GB of GDDR5 memory. Windows 10 Professional is pre-installed.

Tower Chassis with 1400 W Supply

The full-height tower houses a 1400 W power supply and 24 DIMM slots arranged in six channels per CPU, allowing memory expansion up to 1536 GB. An internal DVD±RW drive is fitted. The Quadro M5000 occupies a double-width PCIe slot and carries its own display outputs for multi-monitor setups.

Certified AutoCAD Platform

This configuration matches Autodesk certified specifications for AutoCAD workloads that demand high single-thread frequency and large ECC memory capacity. Buyers who need additional internal storage bays or a second high-end GPU should verify chassis clearance and power-headroom before ordering. The system replaces older dual-socket workstations where memory bandwidth or NVMe boot speed was the bottleneck.

Questions about this item

What PCIe standard does the NVMe M.2 SSD use with its adapter card, and what practical speed limit does that impose?

The 250 GB NVMe M.2 SSD connects through a PCIe adapter card, so its throughput is limited by the PCIe generation of the slot it occupies.

What chassis clearance and power connections does the Quadro M5000 8 GB GDDR5 require?

The Quadro M5000 is a dual-slot card that draws auxiliary power; the 1400 W supply provides the necessary connectors and the tower chassis has room for full-height, full-length cards.

How are the 768 GB of DDR4-2666 ECC modules arranged across the 24 DIMM slots, and which population rule is often missed?

With dual CPUs the 24 slots split into 12 per processor; memory must be installed in matched sets per channel so each CPU gets an identical configuration.
