Description

Hi Jeff, first off thanks so much for your content, only just been introduced to your channel.

I am new to Linux so please forgive my ignorance however I am used to overclocking on mainstream chips. I have a problem though which you may be able to help with?

I have followed your guide/code and others as well as many videos but I cannot get my Pi to overvolt, I am at the point where I have edited the .txt file and found my max freq with 0.05v increase that you can achieve with the firmware voltage limit in place and after using your firmware hack everything seems as if it should work and that I should be able to overvolt beyond the 50000 limit but I can't.

I will try to explain as best I can as to where I am up to;

I have cloned the repository but had to cd into the cd pi-overvolt to be able to compile without an error, not sure why because && cd pi-overvolt was already in the code, now when I run compile I do not get anything to tell me that it has worked it just blinks and then returns me to pi-overvolt, is this normal? I looked at the code and there is no printout so I guess yes? but if not then maybe its not compiling correctly or I am doing something wrong?

I believe I have successfully created the slowcpu systemd service so I think that is all fine.

Now, assuming it compiled correctly the next step I have taken is to go back into the .txt file, increased the OVD=55K, rebooted and then run;

cd pi-overvolt && sudo ./removelimit && vcgencmd cache_flush
echo 3300000 | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_max_freq
echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor\

Then in a separate terminal run;

watch -n 1 ./stats.sh

This is where the problem is! the voltage reports 1V and even if I run a stress test it stays locked to 1V and if I repeat the steps above and increase the OVD to 60K, 70K etc it stays locked to 1V.

Please can you help? what am I doing wrong? is there another way to edit the ovd? is doing it in the .txt wrong?

Research direction

Start by reviewing the repository's compile step, the .txt configuration containing OVD, removelimit, and stats.sh, then compare the reported commands with the slowcpu systemd service setup. Reproduce the reported 1V reading under stress and determine whether the voltage limit is removed; done means documenting the cause and a verified correction or confirming the setup is unsupported.
