Method and computing system for controlling a supply voltage in the computing system. A voltage related indication for use in setting the supply voltage of the computing system is stored, and a supply voltage is set for the computing system based on the stored voltage related indication. A crash of the computing system is detected, and in dependence thereon, an adjusted indication is determined for use in the computing system. An adjusted supply voltage is set based on the adjusted indication, and the adjusted indication is stored for further use of the computing system.
