Confirmed working on Asus ZenBook UX430UNR

[precupstefan]

Thank you very much for developing such a tool. It really helped me when I was about to give up on Linux because of the throttling issues. So as the title states, it's working on Asus ZenBook UX430UNR.

May I suggest adding different presets for each laptop. I know that I can edit the config file to fit my needs, but it took me a while to find this out. I believe that the inclusion of presets will come in handy for plenty of users.

Thanks again!

What do you mean with presets? For instance, undervolt is something that is bound to your specific cpu/system and thus you have to find the setting that works for you. Two identical laptops with the same CPU model can indeed handle undervolt differently due to variations in the CPU binning and/or cooling.

I was referring to the temperature configs. The default temperatures, I believe are quite high for my laptop, so I had to adjust them, but in my opinion it would be nice if there was a config file with recommended temps for my laptop, and upon installing to select that file as config for the service.

Regarding undervolting, I didn't take that in consideration when I suggested this, but (I might be wrong) I haven't seen any reports of CPUs that cant handle a minimum of -75/-100 mV undervoltage. That config might be left as it is or be tweaked at a value that it's safe to assume it won't crash the laptop for most users. I'm no expert at undervolting so I don't know how this issue could be handled.

@precupstefan can you share your config file because i have the same laptop. Thanks

[precupstefan]

@beudbeud , I just changed the temperature values, everything else wasn't modified as I didn't have the time to change them. If you're going to further tweak it, please upload your config.

Note: On the ASUS Zenbook UX430UNR you don't need to use throttled, you can just use the official intel_rapl driver.

throttled works perfectly, but I don't want to run unneeded software.

@klausenbusk , I tested your sugestion. The values still reset after 5 seconds. Any ideea how make them stop resetting after 5 seconds?

Weird, what values are you changing exactly? I'm only changing /sys/devices/virtual/powercap/intel-rapl-mmio/intel-rapl-mmio:0/constraint_0_power_limit_uw.

Could you also post the output of grep '' /sys/class/dmi/id/bios_*?

So we have the same bios version.

I'm using all the commands listed in README

Could you try running only: echo 44000000 | sudo tee /sys/devices/virtual/powercap/intel-rapl-mmio/intel-rapl-mmio:0/constraint_0_power_limit_uw # 44 watt and see if it stick?

[precupstefan]

The command didn't change anything
