Hi, I am having trouble with the stability of my FC6 machine using the said mobo and ARIA case. Compiling of mplayer causes crashing of gcc, encoding using mencoder always ends in mencoder crashing. So I thought of looking into power supply and temperatures. After installing lm_sensors, this is the out put I get. The value of VCore 2 worries me. Can somebody give some pointers?
