Systems, methods, and computer programs are disclosed for reducing dynamic random access memory (DRAM) power consumption within a selected voltage frequency/bin. One embodiment is a method comprising receiving a selected voltage/frequency bin for operating a memory bus electrically coupling a memory controller to a dynamic random access memory (DRAM). The method monitors a bandwidth of the memory bus while operating at the selected voltage/frequency bin. The method frequency switches a clock for the memory bus, based on the monitored bandwidth, between a plurality of predefined frequencies within the selected voltage/frequency bin to maintain a target bandwidth.
