its not bug. But yes, its different way. Im Asus enthusiast, so 90% of my boards are Asus (and not for sale ).

You can still shutdown the modules as you can. It can help you a bit. But ussually Im lazy and finding the best module with PScheck. I have active all cores, but they are at lower P-state (exmaple I leave it at around 3-5 GHz with LN2). The others two are at validation frequency.

PS: nice, not only me is playing Quake :-). Im still more or less active in Quakelive game
