Awesome, thank you for the tool. The 13900K/14900K chips seem to have a 100% failure rate according to some sources because of improperly set power limits by the motherboard manufacturers.

I have a machine on 13900K pre-built by Dell and even though the PL1 was set not as high (200W) and I seemingly never experienced any crashes related to that or overheating in general, but it is still much higher than Intel's claimed TDP of 125W, so I set it down to 150W with your script, and it seems like the temperatures in stress tests have reduced.

I am not that dependant on top-notch performance, I'd rather be on the safer side

Hello, praise your work!
May I ask, can it work on a Linux computer with two cpu?

CPU:
E5-2698B v3 x 2

im running a dell xps 9310 fedora 37
the default pkg limit shows 200/64
i have since set to 22/22

Hello there,

thank you for this nice script!
I have fiddled around a bit, to implement a read-only mode on my end and have come across what seems like a bug.
The script uses a variable called INTEL_PL1_ENABLE_BITS_HIGH in line 252 but this variable is never set.
My guess is that this was supposed to be INTEL_PL2_ENABLE_BITS_HIGH which is set alongside INTEL_PL1_ENABLE_BITS_LOW early in the script.

I'm an i5-12500H user(Which is not supported by Intel Extreme Tuning Utility). My Cpu was getting hot and I didn't want to disable Turbo Boost. So I tried to decrease PL1 and PL2 Turbo boost settings via XTU for better Temperatures. Now my CPU is unlocked and PL1 is set as default to 95w(Should be 45W) and PL2 set as default to 115w(Should be 95w) by Intel XTU.

I tried to delete XTU, reinstall Windows, loaded default settings in BIOS, and updated BIOS to a newer version to fix this issue but none of these fixed my issue. My CPU is constantly hitting 100C on idle and I can't change these settings. Other CPU tuning applications only apply Turbo Boost settings to Windows. But I need to overwrite Intel XTU's default settings. Can I use your script to fix my problem?
