I don't know what your using your PC for, but 12GB of ram is unnecessary. Pull 6GB out for a day of tweaking and see what happens.
Do you have an adjustment called MCH Strap or something simular? Set it to 1600
Set your Vcore to 1.3 and disable C1E
Are you using an aftermarket heatsink or the stock unit? If it's an aftermarket what is it? What are your temps at idle and load?
