lol 10c? hmmmm I have never seen that before. You must be living somewhere really cold lol.
anyway just make sure you have the right temperature, use other programs.
but if your temperature is right, then you have no problems.
the only issue of overclocking is either you run out of power which worse case scenario your computer will shutdown. or your processor over heats.
but since its 10c, then your okay. go ahead and overclock it bit by bit and see how far you can go. just dont get too greedy
