A method for link bandwidth management between two devices in communication through a bus in a computer system. Whether a change condition of the bus having a link is activated is monitored. Change a bandwidth of the bus from a first bandwidth with a first width and a first speed to a target bandwidth with a second width and the first speed or with the first width and a second speed when the change condition of the bus is activated. The bus will operate at the target bandwidth without disabling the link or powering down the computer system if subsequent failure speed management and unreliable speed management have passed.
