Dell R940 Processor Expansion Motherboard

This Dell processor expansion board is the PowerEdge R940 module used for multi-processor configurations that require the additional processor section beyond the base system board. It provides the expansion motherboard for the extra CPU sockets in the chassis and interfaces with the R940 system board, processor heatsink and airflow layout, and the memory population associated with those processors. Compatibility depends on the PowerEdge R940 chassis configuration, supported processor generation, BIOS/iDRAC firmware level, CPU population order, heatsink type, fan configuration, and matching memory population for the installed processors.
