DELL PowerEdge R940 3U Rack Server 4x Xeon Gold 6142 2.6GHz 16-Core 768GB DDR4

Four-socket Xeon Gold server

The Dell PowerEdge R940 is a 3U rack server equipped with four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. It ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 modules and includes a PERC H730P controller with 2 GB cache. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise provide redundancy and remote management.

Upgrade from smaller dual-socket systems

This platform replaces dual-socket servers when workloads demand more than 64 cores or memory beyond typical two-socket limits. The jump is worth it for databases, virtualization clusters or analytics that scale across 64 cores and 768 GB of RAM. Buyers who need only single-thread speed or modest core counts will not use the extra sockets.

12 Gb/s SAS backplane and LGA 3647 socket limits

The storage controller supports SAS and SATA drives at 12 Gb/s, but the 2.5-inch bay count caps internal spindle devices at eight. Memory tops out at 6 TB across 48 slots, so further expansion requires higher-density DIMMs not included. The LGA 3647 socket and C620 chipset restrict future CPU upgrades to the same Scalable generation.
