Does Overclocking Void Your Warranty?

Does overclocking void your warranty? The short answer is: usually, but it depends on the chip, the manufacturer and how far you push it. Overclocking is officially outside the warranty for most chips, yet in practice a modest overclock rarely causes a warranty problem — because a chip that dies from heat or voltage is hard to tell apart from one that died on its own.

The short answer

Both Intel and AMD say, in their warranty terms, that running a chip outside its rated speed or voltage is not covered. That does not mean your warranty disappears the moment you open the BIOS — it means that if the chip fails and the failure was caused by the overclock, the manufacturer can refuse to replace it. Our overclocking basics guide explains what an overclock actually does to a chip, and why heat and voltage are the two things that matter.

Intel’s warranty rules

Intel sells K-series chips as unlocked, which means it expects some buyers to overclock them — but the warranty still only covers the chip at its rated speed. Intel used to sell a separate Performance Tuning Protection Plan that covered overclocking damage, but that plan is no longer available, so there is now no official way to insure an overclocked Intel chip. A modest overclock on a Core i5-14600K is unlikely to kill the chip — our how to overclock Intel CPUs guide shows how to keep it safe — but if the chip does fail and Intel can show it was run far outside its rating, the warranty may not help.

AMD’s warranty rules

AMD’s position is similar: PBO and Curve Optimizer are official AMD features, and using them is generally accepted, while a manual overclock with high voltage is outside the warranty. The line is blurry, because PBO is a setting AMD ships and supports — see our how to overclock AMD Ryzen CPUs guide. A Ryzen 7 9700X running PBO is far less risky, warranty-wise, than the same chip pushed to a fixed high speed with a high voltage.

What about pre-built PCs and laptops?

If you bought a pre-built PC or a laptop, the warranty is from the computer maker, not the chip maker, and overclocking usually voids that warranty too — and on a laptop it is rarely possible anyway. A factory-overclocked graphics card is different: it is sold that way by the manufacturer, so its warranty covers it. Our is overclocking worth it guide makes the same point for pre-built PCs: the parts were chosen and cooled for stock speeds, not for an overclock.

Can they even tell you overclocked?

In practice, a manufacturer usually cannot tell that a chip was overclocked after it has failed — there is no counter that records it. What they can see is physical damage from extreme voltage or heat, such as a burnt chip, and that is enough to refuse a claim. A modest overclock that never overheated leaves no sign. That is why our step-by-step overclocking guide stresses small steps and low temperatures: it is safer for the chip, and it leaves the warranty question moot.

How to overclock without risking the warranty

Keep the overclock modest, keep the temperature under 85°C, and do not use extreme voltage. Use the manufacturer’s own tools — PBO on AMD, or the stock boost on Intel — rather than a fixed high-speed overclock. Our how to fix an unstable overclock guide shows what to do if a setting causes a crash, and our overclocking vs undervolting guide shows how undervolting gives you a cooler chip without any warranty worry at all.

The bottom line

Overclocking technically voids the warranty on most chips, but a modest, well-cooled overclock is very unlikely to damage the chip or to be noticed if it fails. If the warranty matters to you, stick to PBO and undervolting — and if you want more speed without the worry, buy a faster chip instead.
