I overclock in my BIOS for my CPU and no result happens in OS

[ReallyJoker]

I am currently using the MSI 970 gaming motherboard with an AMD Fx 6300 6 core 3.5GHz cpu. From the get go my CPU is only running 1399.67MHz. I am not getting my full 3.5GHz. When I try and overclock it in my BIOS I follow multiple guides of people using same motherboard and CPU and some even same GPU and RAM, for them it works fine, for me nope. On the bios screen it that the cpu should be running at an overclocked speed of 4.2. I do stress tests and the whole 9 yards, and get a whopping 1.3GHz. What am I doing wrong?

I fiddled around with some Bios options and got it working.
