According to one embodiment, an information processing apparatus includes memory modules, a measuring module, a determination module, and a controller. The measuring module initializes the memory modules when the apparatus has been booted and an operating system of the information processing apparatus has not yet been started, measures a temperature of the memory modules at a time of the initialization, and measures a maximum temperature of each of the memory modules when the operating system is running. The determination module determines a first memory module, which has the least difference between the temperature at the time of the initialization and the maximum temperature at the time when the operating system is running, and a second memory module which has the lowest temperature at the time of the initialization. The controller maps memory addresses allocated to the first memory module in the second memory module, based on the temperatures.
