Even though the absolute memory configurations appear differently, all servers contain a balanced one
DIMM per channel configuration running at a memory speed of 1600 MT/s. For the PowerEdge R820 and
PowerEdge M620 cluster, the amount of memory per core is also identical.
The Intel Xeon processor E5-2680 on the PowerEdge M620 is the highest bin 130W part available in that
product family. The Intel Xeon processor E5-4650 is the highest bin processor available in the EP 4
socket product family and the Intel Xeon processor E5-2470 is the highest bin processor available in the
EN product family which supports 8 GT/s QPI speed and 1600 MT/s memory.
