Frequently asked questions
What is the difference between overclocking and undervolting?
Overclocking raises the speed a chip runs at, which usually increases its heat and power draw. Undervolting lowers the voltage supplied to it, aiming for the same speed with less heat. They are sometimes done together, since a cooler chip can hold higher speeds.
Does overclocking void a warranty?
That depends entirely on the manufacturer and the market. Some sell chips explicitly designed to be overclocked, others treat it as out-of-specification use. Terms vary by company and by country, so the wording of the particular warranty is what decides it.
What is a boost clock?
A boost clock is a higher speed the manufacturer itself allows the chip to reach automatically when temperature and power headroom permit. Because it is within the official specification, it is not overclocking.
