I have a AMD Fx6300 Black edition that runs at a speed of 3.8 GHz and turbo to 4.1 GHz. I have a gadget in windows 7 that gives me the clock speed, core temp etc. From what I understand is if you enable turbo in the bios it will overclock when under load if the temperature permits. I have enabled turbo with and without the cool n quiet enabled and yet it won't go over 3.8 GHz when under load. This is the mobo I have http://www.msi.com/product/mb/760GM-P23--FX-.html if that has anything to do with it. Thanks.
