Claim Text:
1. An apparatus, comprising: a multi-layer printed circuit board including a ground reference; a memory controller secured to the printed circuit board; multiple memory module connectors secured to the printed circuit board, wherein the memory controller is coupled to the multiple memory module connectors by signal conductors embedded in a signal layer of the printed circuit board to form a daisy chain circuit, and wherein each memory module connector includes a presence pin; a metal element disposed in a second layer of the printed circuit board and aligned with a first one of the signal conductors coupling the memory controller to a first one of the multiple memory module connectors; a control circuit having multiple inputs and an output, wherein each input is coupled to the presence pin of one of the memory module connectors; and at least one relay coupled between the ground reference and the metal element, wherein the at least one relay is controlled by the output from the control circuit, and wherein the at least one relay connects the metal element to the ground reference in response to installing a memory module into one or more of the multiple memory module connectors.
