Sorry to say this but you would have been better to ask about the build before you ordered any parts, this would have saved you some cash, made you aware of better performing alternative components and most importantly avoided any possible compatibility issues, see my canned text below regarding choosing a compatible CPU and Ram;
For the best and most stable performance you should where possible purchase a CPU and Ram that have been tested and approved by the motherboard manufacturer, this is referred to as the QVL ( qualified vendors list ) understand though that there are too many products released for them all to be tested so other hardware will be compatible but not proven to be.If you confirm that the MB at the attached link is the one that you have purchased I do not see the chosen CPU on the CPU support list
