Chip socket for basic input/output system

A chip socket for connecting a first chip and a second chip having same numbers of conductive pins, comprising:

• a first bottom plate and a second bottom plate directly attached together;
• four first sidewalls cooperating with the first bottom plate to bound a first receiving portion, configured to receive the first chip;
• four second sidewalls cooperating with the second bottom plate to bound a second receiving portion, configured to receive the second chip;
• a plurality of first conductive metal sheets insulated from one another and fixed in an inner side of each of the four first sidewalls configured to be connected to the conductive pins of the first chip correspondingly;
• and
• a plurality of second conductive metal sheets insulated from one another and fixed in an inner side of each of the four second sidewalls configured to be connected to the conductive pins of the second chip correspondingly, wherein the plurality of second conductive metal sheets are connected to the plurality of first conductive metal sheets correspondingly by being inserted in the first receiving portion through the first and second bottom plates.
