The chip supply voltage is divided into 1 and 2 because different chips have different operating voltage requirements. Some chips require lower voltages, such as 1V, to reduce power consumption and heat generation and improve performance and stability.
Other chips require higher voltages (such as 2V) to meet their operating requirements. Therefore, in order to adapt to the needs of different chips, the supply voltage is divided into 1 and 2 options. This ensures that the chip will work properly and provide the required power supply voltage.
He must have upped the voltage!!There is a lot of difference between 1.2V and 0.95V!1.2V can easily burn CPU!!
