Fine but my question is, how they know if the Cpu was overclock it?
About Warranty and box, I talk with them and what I need for RMA is Serial number of the CPU. Serial location is in 2 places, On the box and On top of the chip. so I already have RMA approved.
but like I told you if they have a way to check for overclock cpu, my warranty will be avoid because I overclocked it several time
