CPU showing odd settings after applying XMP?

[CapnShanty]

So first off, I realized my ddr4 ram was not running at 3000 mHz as advertised. So I learned I needed to go and set an XMP profile in the BIOS, which I did (ASUS mobo Ez tune).

That setting also changed some funky thing call "sync all cores" to "auto" for the CPU. I'm not overclocking and I'm using a standard cooler (I know I know I should upgrade lol), should I figure out how to change that setting back or is it not a problem?

Second, now that I have CPU-Z, I see that my CPU is sitting at about 817 mHz instead of 3.4 gHz with random jumps up. Is that just it idling?

I really don't want to hurt my computer I hope I didn't mess something up by enabling XMP ;_;
Will either the RAM or CPU overheat now?

Thanks for any help!

First of all, DDR4 RAM has a default frequency of 2133Mhz and not 3000. Second, the CPU automatically slows itself down to preserve power and manage itself for the long term. It goes down to a minimum multiplier count when not in use. Keep an eye on CPU-Z when the comp is doing something to see the CPU speed go up. There is nothing wrong with your computer, be careful not to mess with the BIOS settings unless you know what you are doing.
