Dual Xeon Gold 5122 workstation

This DELL Precision 7920 tower pairs two Intel Xeon Gold 5122 processors running at 3.6 GHz with 768 GB of DDR4 2666 ECC memory. The system targets professionals who need certified AutoCAD performance and large memory capacity for complex models. It ships with Windows 10 Pro and a 1 TB NVMe SSD on a PCIe adapter card.

1400 W power supply and thermal design

A 1400 W unit feeds both CPUs, the AMD Radeon Pro WX 7100 8 GB GDDR5 graphics card and 24 populated DIMM slots. The tower chassis is engineered to dissipate the combined heat load during sustained rendering or simulation workloads. Fan curves are tuned for quiet operation under typical office ambient temperatures.

24 DIMM slots and expansion headroom

Dual LGA 3647 sockets provide six memory channels per CPU, supporting up to 1536 GB total when all 24 slots are filled. The PCIe adapter for the NVMe drive leaves standard slots free for additional storage or specialised add-in cards. A DVD±RW drive remains fitted for legacy media access.

Questions about this item

How do I install the 1TB NVMe M.2 SSD on the PCIe adapter card in the Precision 7920 tower?

Power off the system, open the chassis, locate an available PCIe slot, insert the adapter card with the M.2 drive already mounted, secure the bracket screw, close the case, then verify the drive appears in BIOS before booting Windows 10 Pro.

When will the 768GB DDR4-2666 ECC memory in the 24 DIMM slots need replacement or upgrade?

The DDR4-2666 ECC modules are rated for continuous operation; plan an upgrade only if workloads exceed the 1536GB maximum supported capacity or if a DIMM fails diagnostics, which the system will report at POST.

What thermal or power limit appears first when both Xeon Gold 5122 CPUs and the Radeon Pro WX 7100 run sustained 100% load?

The 1400W power supply sets the overall ceiling; under full CPU and GPU load the combined draw approaches this rating, so the PSU’s over-current protection will trigger before the CPU thermal throttling point is reached.
