AMD says overclocking blows a hidden fuse on Ryzen Threadripper 7000 to show if you’ve overclocked the chip, but it doesn’t automatically void your CPU’s warranty::AMD explains the hidden fuses behind Ryzen Threadripper 7000 processors and how it will handle warranty claims.
Yeah, I don’t really see much of an issue here. If you get a defective chip back, it’s probably a good data point to know if it was “abused”. Even if it’s just so you can ask more questions, or prioritize problems that show up on non-OC’d chips rather than flat rejecting an RMA.
