FlexMem Bridge (PowerEdge M910 Only)
A FlexMem bridge must be installed in the third or fourth CPU sockets on
the PowerEdge M910 system board to support two-processor configurations.
With FlexMem bridges installed, processor 1 can access DIMMs assigned to
processor socket 3 and processor 2 can access DIMMs assigned to processor
socket 4.
Consequently, if you replace the system board, you must transfer the
FlexMem bridge to the replacement planar.

socket.
