I went through everything I could find, but nothing seemed to add anything else in the OC Tweaker tab.
Though I noticed something strange, in the BIOS my CPU shows up at 4800MHz. I then checked CPU-Z and ASRock's own AXTU.
This is what I got;
In CPU-Z it seems to be switching between 1596MHz and 4790MHz, I've read that this could be eliminated by disabling Speedstep in BIOS which I did to no avail.
And in ASRock Extreme Tuner it shows up as 4800MHz just like the BIOS.
I also checked dxdiag and that shows it at 3.30GHz, but I'm not sure how reliable that is?
EDIT: It seems like k1114 answered this post while I was typing it. I'm gonna try that, thanks for the tip
