A method and apparatus for controlling a DRAM refresh rate. In one embodiment, a computer system includes a memory subsystem having a memory controller and one or more DRAM (dynamic random access memory) devices. The memory controller is configured to periodically initiate a refresh cycle to the one or more DRAM devices. The memory controller is also configured to monitor the temperature of the one or more DRAM devices. If the temperature exceeds a preset threshold, the memory controller is configured to increase the rate at which the periodic refresh cycle is performed.
