Mission-critical 4-socket server

The Dell PowerEdge R940 is a 3U rack server built for workloads that demand four Intel Xeon Platinum 8160 processors. Each CPU delivers 24 cores at 2.1 GHz with a 3.7 GHz turbo frequency. The system ships with 64 GB of DDR4 registered ECC memory across 48 slots and eight 400 GB SATA SSDs managed by a PERC H730P controller.

Organisations needing maximum socket density

This platform suits buyers who require four-socket compute density in a 3U form factor with redundant 1600 W power supplies and iDRAC9 Enterprise management. It is not for deployments that need more than 48 DIMM slots, storage interfaces beyond SATA and SAS, or network connectivity other than the provided dual 1 GbE and dual 10 Gb SFP+ ports.

48 DDR4 slots define memory ceiling

The 48-slot DDR4 architecture sets the practical memory limit at 6 TB when fully populated with supported modules. Buyers planning larger memory footprints must evaluate platforms with greater slot counts, while those staying within this boundary can scale from the factory 64 GB in 16 GB increments.

Questions about this item

Will the 2.1 GHz base clock on the 24-core Xeon 8160 processors sustain 3.7 GHz turbo across all cores under a full-day workload?

The four Xeon 8160 CPUs run at 2.1 GHz base with a 3.7 GHz turbo rating; actual sustained frequency depends on the thermal and power headroom available in the 3U chassis with dual 1600 W supplies.

How loud and hot does the R940 get when the four 24-core CPUs and eight 400 GB SSDs run continuously?

The server uses redundant 1600 W platinum-efficiency power supplies and hot-swap fan modules in a 3U rack form factor; acoustic and thermal output will vary with inlet temperature and workload intensity.

Which memory modules must already be on hand to expand the 64 GB DDR4 installation toward the 6 TB maximum?

The system has 48 DDR4 registered ECC slots and currently holds four 16 GB modules at 2666 MHz; additional DDR4 RDIMMs or LRDIMMs are required to add capacity.
