Intel core 2 quad Q8300 OVER CLOCK HELP?

Set that on back to AUTO until you know what exactly you are doing. Or set it to 10% and let Asus control it. You will burn that board up otherwise. You need to venture out on the web, and visit some of the overclocking sites and learn about this subject. It will take time and patience. It is not set it up and leave it. You will do this in small steps, reach a top that will go backwards now. Then you will back off a bit-maybe twice. And hopefully you system will still be in tact.
