“fuse” implies that the CPU will stop working when it is overclocked, this seems to be more of a mechanism for AMD to let them know that the reason the CPU is not working anymore is because it was overclocked and fried.
Somewhat.
All this fuse does is tell AMD that the chip has had custom clocks or voltage applied to it (this appears to also apply to underclocking and undervolting as far as I can gather)
It does not prove that if the chip is faulty that it must be the OC/undervolt/whatever that caused it.
Think of those water detection strips in other products. They can tell the manufacturer if something has been in a humid environment, but just because it has been doesn’t guarantee that that is what caused the fault to come about.
Yet Apple throws those phones out of warranty regardless of what caused the fault
Apple is the bad exemple
Apple is the bad
That was years ago, the phones have been waterproof for a long time- I would certainly file a warranty complaint with Apple if my waterproof iPhone was damaged from humid air, rain, falling in the tub as it’s rated to survive all those things. In fact, 5+ years ago people were doing tests dropping phones down 30 feet under water and bringing them up just fine.
Laptops on the other hand are not rated for water, and you’re right, a laptop full of purple spill sensors gets denied unless you bitch hard enough.

Apple will not cover water damage, even though the phone has protection.
No, this means something else in chip design. For example, an AVR microcontroller can be configured by blowing some fuses. Here is an introduction: https://www.ladyada.net/learn/avr/fuses.html
Understandable but this is not a fuse in common usage of the word, which is used to break a circuit to protect against over-current. Rather it’s an part that changes state irreversibly (much like a fuse would) when something happens. There is no implication that it would cut off the power to the CPU in this sense.

It’s just an electronic component, like resistors and transistors. Samsung has something similar in their phones called Knox.
But in the world of electronics fuses and circuit breakers exist to trip when too much voltage is applied to protect the circuit. That’s their generally agreed upon definition.
A fuse is just an electronic component. It can be used for circuit protection, but it doesn’t have to be. For example, a transistor doesn’t have to be an amplifier, a resistor doesn’t have to be for dimming bulbs, etc.
Fuses in this sense are write-once data. Once the fuse is burnt, only physical repair could revert the change. These are used as one-way-doors (like the Nintendo Switch firmware upgrade fuses https://switchbrew.org/wiki/Fuses#Anti-downgrade) or tripwires (like Samsung Knox https://en.wikipedia.org/wiki/Samsung_Knox#e-Fuse)
How come I bought first gen threadripper cpu for around $400 and mobo $400, but now their prices are like $2000 for cpu and $1000 for the mobo?
I’d like to get more pcie lanes than on 7950x.
Lack of competition, manufacturing consolidation, and inflation.
I picture the aurhor of this fearmongering title evil laughing while writing it.
You’ve said that twice on two separate posts now.
Either way, there is nothing fear mongering about this title, the article even confirms the title directly from AMD themselves.
This was also present in Threadripper 5000, per the article.
Not a new thing, some motherboards even do this.
That’s fair, just like Apple devices (phones and iPods) have/had a detector in the headphone port for water damage.

Lotta manufacturers have done that. I had an Android phone back in the day that was notorious for false positives on the moisture detectors. The phone was a piece of shit and a lot of people wrongly got denied on warranty claims because of supposed moisture.
So the purpose is to protect them if someone overclocks and fries it, meaning they know if you take it in under warranty and say you want this faulty part replaced?
pretty much, also stops any techs or engineers looking into possible problems of the product from spending hours wondering what went wrong before the user says (if at all) “oh yeah, i overclocked it btw”.
It’s only fair
