Don't use that program to OC your CPU. It's a decent program to monitor temps, especially thermal margins but DO NOT autoOC using it.
Go through BIOS. I'm familiar with the program, I used to be a big fan over majorly overclocking FX-6300's.
Go into BIOS, disable turbo core, increase your core mulitplier to reflect 4.2 ghz and then increase your voltage a bit over stock. Run Prime95 while using HWmonitor and/or AMD Overdrive (all free programs) to monitor your temps. I believe your CPU should be kept under 70C maximum if I remember correctly. The goal is obviously much lower than that.
Keep bumping up your core multiplier and increase your Vcore by 0.025 increments at a time. Stress test it and see what happens. If it freezes or restarts, you need more Vcore. Keep doing this until you've found your highest CPU frequency with a temperature that you are comfortable with.
Let me know if you need any additional help.
I'd suggest a different aftermarket cooler, but thats my opinion. Evo 212's are very overrrated and really limit your ability to OC. I was able to get my FX-6300 to 5.0 ghz using a Corsair H60i. It's worth the extra money if you really plan to overclock and game.
