I have been overclocking my cpu and got it to 3.6ghz. Now while playing l4d2 it was unstable hanged and restarted my comp. So i went into the bios and went to increase voltage from 1.375 to 1.400 but it's all now gone to default. When i go into bios it states my multiplier is x18.5 but on cpuz and core temp i've gone back to 3.1 and the multi has gone down to x15.5 also.
Any ideas?
