PowerEdge R940 3U rack server

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 5118 processors running at 2.30 GHz with 3.2 GHz turbo. Each chip provides 12 cores for a total of 48 cores across the system. It ships with 512 GB of DDR4 2400 MHz registered ECC memory across 16 slots and an Intel C620 chipset.

Four-socket density for heavy multithreaded loads

This configuration suits workloads that scale across many cores such as large databases, virtualization clusters or high-performance computing tasks. The eight 300 GB 10K SAS drives and PERC H730P controller deliver hardware RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need GPU acceleration, front-access high-speed bays or single-thread frequency above 3.2 GHz should evaluate other platforms.

Maximum memory capacity of 6 TB across 48 DDR4 slots

The board supports up to 6 TB of DDR4 registered ECC memory when all 48 DIMM slots are populated. The current 512 GB installation leaves substantial headroom for future expansion. Verify that any additional modules match the DDR4 2400 MHz registered ECC specification for compatibility.
