How to Tell if CPU Voltage Is Too Low: Identifying Stability Issues
Our CPU needs the right amount of voltage to operate properly; too low voltage can lead to instability, system crashes, or an inability to boot. This can happen when attempting to undervolt the CPU to reduce power consumption and heat, a common practice in the quest for energy efficiency and quieter operation.
