So for some reason on my laptop I suffer from severe throttling issues when bdprochot is enabled, putting my cpu at a measly 400 MHz from it's 2.8 cap according to cpufreq-info and 380 mhz from 2.6 according to windows task manager.
It persists across 3 different drives, 7 reinstalls of windows 10 and 7 reinstalls of 3 different linux distros. I've tried it on steam OS, Ubuntu gamepack and Lubunt. In windows I used throttle stop but that's not a thing on linux. I use an external fan lowering my temps with bdprochot off through throttlestop to the lower 40s and even without it I generally cap out at 67 and avg at 50 as such I'm not to concerned about the rumored heating issues from bdprochot.
I tried the msr tools fix but that doesn't work I get the message saying
wrmsr: pwrite: Operation not permitted.
This is a laptop so there are no bios power settings.
I followed a guide here (quote below)
I came across the same problem and I found a solution which works for me. You'll have to download cpufrequtils.
Run every command in Terminal: Note: The '-c' argument is for core number. If your CPU has four cores, run the given command for 0 through 3 and if your CPU has eight cores, then run the command for 0 through 7.
sudo cpufreq-set -c 0 -g performance sudo cpufreq-set -c 1 -g performance sudo cpufreq-set -c 2 -g performance sudo cpufreq-set -c 3 -g performance sudo cpufreq-set -c XX -g performance sudo modprobe msr sudo rdmsr 0x1FC
The XX here is the number of your core. After this step you'll get an output which you need to note down and then use in the next command.
sudo wrmsr 0x1FC XXXXX
Here, XXXXX is the output from the previous command execution. Finally, to check if it has worked, run:
I excluded the line due to the fact that it cause an error output
sudo cpufreq-set -c XX -g performance
This worked on steam OS which is based on debrian 8: jessie but doesn't seem to work on lubuntu it only seems to edit the settings to performance
The output from rdmsr changes every time I reboot.
it's also sort of a pain to deal with all these commands every time I launch just to make my pc usuable.
I changed the secure boot to on when I swapped to lubuntu in order to add the boot file to the load order so that might be whats preventing wrmsr from working.
Even then it doesn't change the inherent problem that this issue persists as well as the fact that I have to spend time in the command line every time I boot up which let's face it is a huge headache.
