Device failure is a significant concern. As noted several times throughout this text, only quality components should be used in an overclocked system. If your system is factory built, you may not have the best components, but you can still take care to cool and configure your system properly. Remember that overclocking can void product warranties. Multiplier overclocking voids processor warranties, while front-side bus overclocking voids agreements for nearly all system components. Trying to get product replacements or refunds for damages incurred during overclocking is unethical if not illegal. Deceitful tactics increase hardware costs for everyone and have compelled some companies to implement anti-overclocking technologies.
