Right, but I wonder, why you buy expensive stuff and do not know the essentials, PotNoodles?
HT, Speedstep, TM and so on can all be issues for bad OC results and hick ups of your cpu.
But as I see on your 680 and your 4GB Ram (which should be at least 6 or better with your video card 8 and more GB), you are not well prepared, but already overclocked your rig. That is strange amd it seems, that you just pulled some sliders in the bios to 4 GHz and not read an overclocking guide for your specific cpu and its stepping/revision/serial number.
You should invest some minutes for your OC, because you are currently running without knowing, what actually happens to your system. Not that you soon get a destroyed system, because it is running on bad settings for its lifetime.
Just a tipp!
