I overclocked my fx-4100 to 4.0ghz by changing the multiplier, turning off cpu throttle and amd amp. Anyway when I run cpu temp It doesnt show the cores it only shows one core, core0 it still reads temps on idle it runs about 6 Degrees Celsius and when I run prime 95 it runs at about 31 degrees. point is I need to know how to view all my cpu core temps.
Try AMD overdrive and/or HW monitor.
(Don't use AMD overdrive to overclock, just check CPU status for temps.)
