FSB speed is dropping

vendredi 20 février 2015

Hi i dont know if this is normal but my fsb is going from 200mhz to 160 sometimes causing stutters while gaming, i have no idea whats causing this.

processor is fx 8320

mobo m5a97 LE r2.0

12v rail lowest is 11.69v

5v stays at 5v

3.3v is at 3.113 lowest

any ideas, is my mobo broken? power supply? what could cause FSB to drop?

thanks!
