DELL Precision 7920 Tower 2x Xeon Gold 6144 768GB 250GB NVMe Radeon Pro WX 7100 desktop PC

Precision 7920 Tower dual Xeon workstation

This Precision 7920 Tower ships new with two Xeon Gold 6144 processors, each running at 3.5GHz with eight cores. The pair delivers 16 physical cores and 32 threads through Hyperthreading, supported by 768GB of DDR4-2666 ECC memory across 24 DIMM slots. A 250GB NVMe M.2 SSD on a PCIe adapter card provides the boot drive, while a Radeon Pro WX 7100 with 8GB GDDR5 handles graphics. Windows 10 Pro is pre-installed.

DDR4-2666 six-channel memory limit

Memory runs at 2666MHz in a six-channel topology that requires both CPUs to be populated for full bandwidth. The board offers 24 slots and the supplier notes a maximum of 1536GB total capacity, though this unit carries 768GB. Only DDR4 ECC modules are compatible; other DDR generations will not fit. The NVMe SSD uses a PCIe adapter card rather than a native M.2 slot, so lane allocation depends on the riser configuration.

Dual LGA 3647 CPU constraint

The system uses two LGA 3647 sockets locked to the Xeon Gold 6144; processor upgrades are restricted to parts that share this socket and the platform power budget. The 1400w supply feeds both CPUs, the Radeon Pro WX 7100 and all populated memory slots. Buyers who need a different core count, clock speed or a newer Xeon generation cannot swap processors on this motherboard.
