So, I have an i5-2500k in an Asus Maximus IV Gene-z/GEN3 mobo. Whenever I overclock my CPU to 4.2ghz (the overclock is stable, tested it with intelburntest), the onboard adapters (LAN, audion, etc.) simply fail. When I boot into my overclock everything is working except my PC doesn't recognize the network adapter and I don't have sound... then when I reset everything back to normal sound comes back and so does the internet... I'm pretty sure I did everything right in the bios config and my overclock IS stable.
