Abstract
An impedance adjusting apparatus of a controlling chip on a computer mainboard. When a computer is turned on, BIOS automatically detects the actual usage of the memory sockets, and then sends corresponding control signals to adjust the impedance of the impedance adjusting apparatus for a better impedance matching between the controlling chip and the memory sockets. The signal reflection is dramatically reduced and the operation bandwidth is widened.
