News AMD says overclocking blows hidden fuses on Ryzen Threadripper 7000 to show if you've overclocked the chip, but it won't automatically void your CP...

Why do you need hardware fuse?
Software detection and throttling algo should be norm.

There's embedded software on the CPU? When you send it out for RMA warranty claim, you only send the CPU.

Not sure what people are complaining about.

Many cars can reach 200+ mph velocity. And the car makers gladly advertise that their cars can go from 0 to whatever in X seconds.

Now, if somebody drives said car at really high speed that it that they lose control, and crashes their fancy car, who is to blame? Definitely not the car manufacturer!

The Veyron/Chiron can theoretically hit 250mph+, however there's only one venue at which that has ever officially been done and that's at VAG's test track, under normal conditions, ie. on public roads or even at a local track or whatever that physically doesn't have the room needed to hit that top speed, no one's hitting that crazy theoretical top speed as it's only possible to actually pull off under special conditions.

Last thing I read is that if you blow a fuse, it does not void your warranty. Obviously, the fuse isn't a completely reliable barometer, and it could blow for other reasons/causes. So, not voiding the warranty makes plenty of sense.

Sounds like something that could be defeated in court unless AMD can prove beyond a reasonable doubt that the "hidden fuses" can only be blown if manual overclocking is enabled and not any other way, and I doubt they can. If I remember right Intel for years had denied warranty coverage to anyone who overclocked their processor unless they bought their special insurance, but I can't remember any stories about people being denied coverage.

The fuse would get programmed by the motherboard BIOS when you went to enable overclocking and accepted the terms. There is no ambiguity.

Consider the main use case for these workstation CPUs: workstations supplied by big OEMs. Those do not support overclocking and their firmwares do not expose any settings for it. This fuse being set would be a red flag of the customer having taken the CPU out for overclocking on a DIY motherboard.

OEMs could alternatively vendor lock the CPU to their own firmwares, but I don't know if that feature is supported on Threadripper.
