Hi justapost,thanks

In addition to your post,it seems that AMD has gone the route of lowering certain voltage levels(I/O related?) when it comes to SB750.I'm sure you have seen the slide before here (1.8V/3.3V level shifter circuit,needed for direct connection of Phenom and SB pins).Hopefully,the integrated clock generator in SB750 will eliminate the idle freezing problems and bring overall better clocks.
