Four-socket Xeon Gold 5120 server

The Dell PowerEdge R940 is a 3U rack system with four Intel Xeon Gold 5120 processors. Each CPU runs at 2.2 GHz with 14 cores and reaches 3.2 GHz turbo. The platform targets workloads that demand high core counts in a compact rack footprint.

Upgrade from dual-socket density limits

Moving from a two-socket server to this four-socket design doubles the installed processor count to the platform maximum of four. The jump is worth it when licensing, memory capacity or thread-heavy applications scale better with additional sockets than with higher-frequency parts.

512 GB DDR4 with 6 TB headroom

Sixteen 32 GB DDR4 modules fill 16 of 48 slots, leaving 32 slots open for expansion up to 6 TB. The PERC H730P controller manages the two installed 800 GB SATA SSDs and additional drives; storage-heavy datasets that exceed the current bays will require external enclosures or a different chassis.

Questions about this item

What rack height and mounting hardware does the R940 require?

The server occupies 3U of rack space and ships with ready rails for installation in a standard rack cabinet.

How are the four Xeon Gold 5120 processors and 512 GB of DDR4 memory installed, and what step is often missed?

All four processors are pre-installed in the LGA 3647 sockets; the 512 GB arrives as sixteen 32 GB DDR4 modules populated across the 48 slots, so the common oversight is not verifying the memory configuration matches the 2400 MHz registered ECC specification before powering on.

Which components will need replacement first in the PowerEdge R940?

The two 800 GB SATA SSDs and the PERC H730P controller battery are the primary maintenance items; the hot-swap 1600 W power supplies and fans can also be replaced without downtime.
