Overclocking Fedora 27

I recently purchased a new ASUS TUF X299 motherboard and an Intel i9 CPU with 16 processors (32 threads). The CPU runs at a default of 2.8 GHz but is actually capable of being overclocked to much higher speeds on this Fedora 27 box.

I really don’t care about getting the last bit of performance out of my computer; I really would rather have reliability than speed. But I do want a bit more than 2.8GHz.

After fussing with the system for a few days and not getting any stable results, I decided that it would be interesting to try reinstalling fedora from scratch. For the last several versions I have been doing upgrades rather than reinstalls, so I thought I might as well try the reinstall. That did work for me and I was able to get to my target of 10% overclocking without any trouble.

You should note that the Fedora Project recommends not overclocking your CPU. https://fedoraproject.org/wiki/HardwareProblems

The bottom line in this case is that Fedora should be installed from scratch on a host in order to ensure best performance from these newer and very powerful CPUs.
