You will need an aftermarket cooler to get to those clocks to run stable. If you have a stock cooler, you might be able to get to 3.2-3.4GHz pretty easily by increasing your BCLK in BIOS. You should spend a couple hours researching your motherboard's ability to OC before changing anything. Also be prepared for anything including knowing how to reset your CMOS.
I already listed my CPU cooler above and it is not a stock cooler
