A method for dynamically allocating link width of a riser card is disclosed. The method is suitable for a system including a riser card. In the present method, the number and the positions of cards inserted in the slots and functioning normally are detected so as to decide the link widths allocated for each of the cards. Next, a link width retraining procedure is executed so as to provide a proper link width for each the card to use. In this way, the present invention is able to achieve the optimization of allocating link widths without being limited by the types and the number of the cards disposed on the riser card, which is advantageous in saving the design cost of the riser card and enhancing the convenience to use and handle with the riser card.
