Fuses coming to CPUs... or not

(1/4) > >>

PKTKS:
Today  I found myself reading all these tech tips and stuff that nowadays pop everywhere thanks to tubers devotes...

This folk and others raised a serious concern as if FUSES are now integrated into CPUs as well and no longer a premise of some MCUs AVRs...

https://linustechtips.com/topic/1404447-yikes-lenovo-is-vendor-locking-amd-ryzen-cpus-via-psb/

In particular LeNovo seems to be using that filthy trick widespread across the every_day_less_trusty  UEFI boots..

Any reasonably reliable information welcome as well as some sort of precautions of the second hand CPU/MCU market...

you know FUSES are a very shitty thing to deal with..  ???

to say the least

geez i hope that would be that simple...

But as far as it seems they moved the feature from the always locked by default server market to the consumer CPUs..  and that is deeply buried into these UEFI firmwares..

so...  the second hand market will have a TSUNAMI impact with these locked FUSES by default .. and also the boards with UEFI already locked at factory..

in other words.. the carve a way to make CPU+board a landfill garbage..
almost hardly impossible to  fix or upgrade ... 

as far as it seems ahead..

x86 is becoming a unreliable liability

An exchange of the CPU is not that common anyway. After a few years there is anyway a chance that a different socket is used or at least the question of the old MB still supports the a new CPU.  With the extra secure boot part the CPU and MB stay together - so use them longer or change CPU and MB as a pair. An old CPU, that is replaced because it got too slow has anyway only a rather limited value to be reused.

There is anyway a tendency to more notebooks and compact PCs, where a CPU change is impossible or difficult anyway.

I just watched a Chris Barnett video (explaining computers - Y/T) on swapping a CPU. A number of minutes of the vid was spent wondering/hoping that the OS wouldn't take offence of the hardware change and what to do when the inevitable need to beg for forgiveness when the OS deems your own HW manipulation unworthy.
