Stock voltages for 3900x components
Stock voltages for 3900x components
It should run at 1.46 volts during idle. The latest BIOS from ASUS Crosshair 8 Hero suggests the CPU can handle higher voltages, so sticking to the stock voltage might be more optimal. Your manual setting of 1.3V is reasonable but could limit performance.
It's typical for the system to operate at maximum voltage to match the current demand, ensuring optimal performance while avoiding significant losses.
