A method of managing system resources managing resource utilization for a system board that includes a plurality of processors, memory associated with each of the processors, a plurality of voltage regulators configured to regulate voltages applied to the processors and memories, and a board manager configured to manage resources of the system board includes communicating operating condition information from the board manager to controllers of the voltage regulators independent of the processors also communicating with the controllers, the operating condition information received by each controller indicating a computing load for the processor regulated by the voltage regulator controlled by that controller. The method further includes controlling the voltage regulators based on the operating condition information, so as to set the power limit of the voltage regulators in accordance with the processing load indicated by the operating condition information communicated by the board manager to the controllers for each processor.
