Overclocking help

1. i wouldnt start overclocking unless you bought an aftermarket cooler

2. overclocking is simply to get more preformance out of your system, i see about a 25% gain in video rendering from running my system at 4GHz over 3.2GHz... and its also got a nice ring to it  

3. if you go into your BIOS settings (or UEFI config) there should be a cpu section, raise the cpu multipier a few notches at a time... checking for stability each time (i suggest prime 95, and speedfan for monitoring temps) and when it becomes unstable raise the VCore until its stable again
