Instead of 100? So when I put my multiplier to 45 or 46 I always end up below 4.5 or 4.6 ghz.

It's completely normal for it to do that. It has to fluctuate since it's almost impossible to keep it at constant 100.

because you have CPU Spread Spectrum enabled in your BIOS/UEFI, disable that and it will be 100.

Thanks for the quick replies. Is the spread spectrum something that is important for safety/shouldn't turn off?

It's used to help eliminate EMI. It's typically fine to disable it if it helps with your OC.
