I have an AMD FX-8350 on an ASUS Crosshair V Formula Z that I just overclocked to 4.8GHz following the ROG guide. All worked well, with the exception of my sound not working anymore. I've read a little bit and seen that sometimes there needs to be an AGP/PCI lock, and that there's a setting somewhere or enable it. Problem with this is, I can't seem to find out how to enable it, of that's actually the problem. Could that be it, and if so, how can I enable it?
