Yes, overclocking can void a warranty for many manufacturers. Most hardware manufacturers include clauses in their warranty agreements that specify any modifications, including overclocking, can lead to a voided warranty. However, the extent to which this applies can vary by manufacturer and product, so it’s always best to check the specific warranty terms before proceeding with overclocking.
