So yes I tried it, and I didn't see any difference after I applied the dsdt. I think it is because I've installed many kexts so maybe they overwrite dsdt? (I'm very noob at this topic, I don't even understand where do kexts and dsdt kick in and how they cooperate to each other).
My system is unstable, but it could also be because I am overclocking it. Do you think uninstalling kexts would help to stabilize the system? Will install too many kexts affect system stability?
Thank you my friend, your response is very fast.
