PowerEdge R940 four-socket server

The Dell PowerEdge R940 is a 3U rack server built for organisations that need dense, four-socket compute in a single chassis. It ships with four Intel Xeon Platinum 8160 processors, each delivering 24 cores at 2.1 GHz, and 128 GB of DDR4 registered ECC memory across eight 16 GB modules. The platform targets database, virtualisation and analytics workloads that benefit from high core counts and large memory capacity.

Dual 1600 W redundant power and thermal design

Redundant hot-swap 1600 W platinum-efficiency power supplies share the load and maintain operation if one unit fails. The 3U form factor accommodates the cooling required by four 24-core processors and the PERC H730P storage controller under sustained utilisation. Acoustic output scales with workload intensity in a typical data-centre rack environment.

48 DIMM slots for up to 6 TB DDR4

The system provides 48 DDR4 memory slots with a maximum supported capacity of 6 TB, allowing memory to grow with application demand. Buyers who need more than 6 TB of RAM or who require a different memory generation will need a different platform.

Questions about this item

How do I install the Xeon 8160 processors into the LGA 3647 sockets without bending pins?

Align the triangle markers on each processor with the socket keying, lower the carrier straight down, and torque the captive screws in the printed sequence — uneven pressure bends the delicate pins.

Which components will need replacement first in a 24/7 deployment?

The H730P RAID battery and the 1600 watt power supply fans are the typical wear items; both are hot-swappable and can be changed without shutting down the server.

What thermal limit appears first when all four 24 core CPUs run at 3.7 GHz turbo continuously?

The dual 1600 watt redundant supplies hit their combined output ceiling before the CPU thermal throttling engages, capping sustained all-core turbo performance.
