I have a laptop with an Intel(R) Core™ i9-14900HX (2.20 GHz) processor. These processors are generally a bit problematic. In Windows, I can reduce the p-core values by two using XTU without any issues. But if I don’t, the device constantly gives errors and shuts down.
I’ve tried many things with AI to fix this, but I couldn’t succeed with Fedora.
How can I permanently fix this on Linux?
I know nothing about shutting down parts of CPU, but what I can say is that if I’d paid that much money for a machine which had to be semi-disabled to operate correctly, it would be going back as “unfit for use” and I’d be requesting a full refund.
Why on earth would you put up with that level of quality or service?
Saying this, if you can’t find a way to turn off processors entirely, you could probably achieve the same result (lower thermals) by capping the maximum frequency that the cores are permitted to run at with sudo cpupower frequency-set -u 3GHz, where the speed would be something you can set via trial and error.
However, my first choice would be to send the thing back and get something which actually works.
