I lock hotplug lock to make sure 4 core are running. And adjust the min and max cpu speed to 1704mhz and above, which are exceeding original cpu max speed (1600mhz), and run stability test. I notice the cpu speed is unstable and even drop down to 800mhz and doesn't raise up to the cpu speed I set.
I wonde if:
1. During stability test, is it normal if cpu speed automatically drop to 800mhz ane doesn't raise up again?
2. Is it normal? If my phone don't crash on the test but cpu speed drop, does it mean I shouldn't over clock to that speed?
3. Is there a solutions for the cpu speed dropping? I tried to restore voltage and use the default to run overclock test but CPU speed still dropping.
4. What's the cause of CPU speed drop?
That's all my question. Thank you for spending your time reading my post. Hopefully someone can solve my problem.
Than you very much!
