They say "overlocking voids warranty" but they really don't have a proof its been overclocked. Not sure about CPUs but for videocards, isn't it economically possible to implement a one chip counter/EEPROM solution that measures frequency of the bus?
Things like printer, security system etc stores logs such as alarm counts, total page since manufacutring and such parameter onto non-volatile EEPROM.
What if they implemented a one chip counter/controller that will continuously monitor the bus speed(assumes multiplier is locked and can't be tampered w/o voiding warranty) and log the highest frequency it sees?
The entire chip can be covered in epoxy to resist tampering w/o leaving evidence and only allow write command to EEPROM from the controller itself which is encapsulated in epoxy.
This information can then be read through the interface when sent in for repair to see if it has been clocked beyond allowance.
