Circuit diagram for the ECS C51-M940 mainboard, a 930 KB PDF. The model code points to an NVIDIA C51 chipset board, and M940 likely relates to the AMD socket it supports, though the name does not spell this out. The schematic is useful for checking the VRM phases, memory and chipset voltages, standby circuits and reset and power-good signals when a board fails to start. Open it in a standard PDF reader. Make sure the revision silkscreened on the PCB matches the document before trusting component designators or values.
