I am a newbie to overclocking and I need help

[xforever82]

I decided to buy a rampage v and i7 5960x
With corsair ddr4 2666mhz
I do not want to over clock my cpu I want to use it as normal
Currently I set xmp for bios but when I check the task manger I still see its at 3.24ghz what should do?
As I am in a total lost mode
Please help me thanks
