It's a good motherboard, a... decent-ish CPU. Look up some tutorials, you'll find that it's really all raising by increments, testing for stability, monitoring temperatures. Running Prime95 for 5 minutes is not sufficient. Run it for a couple hours at least, and when you're getting ready to go to sleep, turn it on and let it run overnight. If it's still going in the morning, it's stable. 62c on the core is a bit low, a lot of people recommend that, but really it's safe to go up to 70, or even 75 without reducing the lifetime of your CPU.
