Alrighty, here's the deal with warranty. If you are in the US, you are covered under the Magnuson Moss Warranty Act, because applying EXPO also changes other settings that the motherboard auto defined. Because the MOTHERBOARD entered in the unsafe settings and not you, you wouldn't be liable for this kind of damage, the motherboard manufacturer would. While yes the manufacturer of a product has to prove you caused the damage, in this particular case since the motherboard was auto defining unsafe values as safe, it would be the motherboard manufacturer that would be liable for this. Also why did AMD not test these chips beforehand? If over 1.3V SOC voltage instantly kills CPUs, AMD should have known about this prior to launching them. This is mainly AMD's fault for not testing their products and telling motherboard manufacturers what values to NOT auto define. Imagine Ford shipped you a car that should work in ideal conditions, but when driving below sea level, the engine blows up because of the higher air density. Why would that be YOUR fault because you drove it in a place that was 200ft below sea level? It's not like you are visiting a volcano or going to the core of the earth which would need a special kind of car, it's 200 feet below sea level.
