Unfortunately, there is not any safe method enabling to change a multiplying ratio of the bus frequency by the hardware at home.
Similar to changes of the bus frequency, you can try to bypass the limit on the voltage supplied to a processor. To do this, you should isolate some processor’s outputs.
A processor informs a motherboard about its power of five voltage outputs VID (Voltage ID): from VID0 to VID4 (outputs B120, A120, A119, B119 and A121 accordingly). The combination of these contacts forms a binary number specifying the voltage that should be supplied on a processor. Each output may be either in the state of logical low or logical high. Thus, the entire voltage spectrum is described – from 1,3 to 3,5 V.
