Dual Xeon Gold 6144 workstation

The Dell Precision T7920 pairs two Xeon Gold 6144 processors at 3.5 GHz for 16 cores and 32 threads. It is built for engineers and designers who need sustained multi-threaded performance in CAD, simulation or rendering workloads.

1400 W tower with six-channel ECC memory

A 1400 W power supply feeds the dual-socket LGA 3647 platform and the Radeon Pro WX 7100 8 GB GDDR5 graphics card. Six-channel DDR4-2666 ECC memory across 24 DIMM slots delivers 768 GB today and supports up to 1536 GB. The 500 GB NVMe M.2 SSD rides on a PCIe adapter card, and a DVD±RW drive is included.

Replaces single-socket CAD towers

Moving from a four- to eight-core single-CPU system adds the second Gold 6144 and doubles thread count for heavy rendering. The jump is worth it when project files exceed 32 GB and the 20-times-RAM guideline pushes you toward 768 GB or the 1536 GB ceiling. Buyers who need more than 500 GB of primary NVMe storage or certified Nvidia Quadro drivers should look elsewhere.

Questions about this item

Does the Radeon Pro WX 7100 use NVMe for its frame buffer?

No, the Radeon Pro WX 7100 uses 8GB GDDR5 memory for its frame buffer; the 500GB NVMe M.2 SSD is the system boot drive installed via a PCIe adapter card.

How many DDR4 DIMM slots does the T7920 tower provide for memory expansion?

The chassis has 24 DDR4 DIMM slots, 12 per CPU, supporting up to 1536GB total ECC memory at 2666MHz.

What is the correct order for populating the 24 DDR4 slots when adding memory to both Xeon Gold 6144 CPUs?

Fill the 12 slots for the first CPU following the six-channel sequence before populating the second CPU's 12 slots to maintain balanced memory channels.
