    Abstract: A system board is provided that includes a connector. The connector includes a pinfield. The pinfield includes a set of differential signal conductors to correspond to pins of a set of differential signaling pairs; a set of one or more auxiliary signal conductors to carry auxiliary signals; and a plurality of thru-hole ground vias adjacent to a particular one of the auxiliary signal conductors in the set of auxiliary signal conductors. A method for improving signal integrity in a computer interconnect can include carrying differential signals on a set of differential signal vias in a connector pinfield; carrying sideband signals on a set of sideband vias in the connector pinfield; and reducing via-to-via crosstalk between a particular one of the sideband vias and one of the differential signal vias through one or more thru-hole ground vias adjacent to the particular sideband via in the pinfield.

    Abstract: Techniques for reducing resonance in contact fingers of a connector are described herein. An example of a device in accordance with the present techniques includes an add-in-card that includes a circuit board and an edge contact finger disposed on an outer surface of the circuit board. The add-in-card also includes a resonator disposed in an internal layer of the circuit board and coupled to the edge contact finger, wherein the resonator reduces a resonance in the edge contact finger.
