Dual Xeon Workstation for CAD

The Dell Precision 7920 tower pairs two Xeon Gold 6144 processors, each with eight cores running at 3.5 GHz, to deliver 16 cores and 32 threads. One terabyte of DDR4-2666 ECC memory fills 12 of the 24 available DIMM slots. A Radeon Pro WX 7100 graphics card with 8 GB of GDDR5 memory drives professional 3D viewports. Windows 11 Pro is pre-installed on a 250 GB NVMe SSD mounted on a PCIe adapter card.

1400 W Power Supply Handles Peak Loads

A 1400 watt power supply feeds both CPUs, the full memory complement and the graphics card under sustained rendering workloads. The tower chassis provides space for airflow across the dual-socket motherboard and the add-in GPU. No liquid cooling or supplemental fans are described in the configuration. Acoustic output will vary with workload intensity and ambient temperature.

24 DIMM Slots Allow Future Memory Growth

The LGA 3647 platform exposes 24 DDR4 slots, leaving half the capacity free for expansion up to the 1536 GB platform limit. The NVMe boot drive occupies a PCIe adapter rather than an onboard M.2 slot, leaving additional PCIe lanes open for storage or capture cards. A DVD±RW drive is included. Buyers who need a second high-end GPU or more than 250 GB of primary storage should plan for additional drives and brackets.

Questions about this item

How do I install the 250GB NVMe M.2 SSD with its PCIe adapter card in the Precision 7920 tower?

Power off, open the side panel, insert the M.2 drive into the PCIe adapter at the keyed slot, secure with the small screw, then seat the adapter in a free PCIe x16 or x8 slot and close the case.

What memory maintenance or expansion does the 1024GB DDR4-2666 configuration need later?

The system has 24 DIMM slots with 12 per CPU and supports up to 1536GB total; add matching DDR4-2666 ECC modules in matched sets per processor to keep six-channel performance.

What thermal or power limit appears first when both Xeon Gold 6144 CPUs run sustained 3.5GHz loads?

The 1400W power supply and dual-CPU cooling are rated for the 16-core, 32-thread workload; sustained all-core turbo stays within the platform thermal design without throttling.
