Re: cpu overclocking

It just reads from the CPU hard coded info.  Use i7z-git from the AUR.

AUR packages • Zsh and other configs

Re: cpu overclocking

yepyang, please edit your post.
When posting configs, code or command output, please use [ code ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and - in case of longer listings - more convenient to scroll through.

Re: cpu overclocking

yepyang, please use a space or two between sentences. You shouldn't end every sentence with an exclamation mark.
