820-2936-B Missing one slot of RAM

[2click]

Hi, I have this board which doesn´t recognize the lower slot for the ram... is there anything that can be done to repair that? I have tried both dimms in the upper slot and they both work fine.... thank you!

Usually cracked solders near the edges of the slot.
You can use a RAM card tester and see which LEDs stay off; then follow the lines in schematic/boardview.
