How safe is the memory overclocking iosa voltage?

Memory overclocking iosa voltage is not higher than 10%. According to relevant public information, the safe voltage range is 10%, and memory overclocking will increase the temperature of the whole system, so attention should be paid to heat dissipation to ensure that the memory temperature is not too high. When overclocking, it is necessary to gradually increase the frequency and voltage, and do not adjust it to the highest value at one time, otherwise it will lead to system instability, collapse and other problems.
