my first overclock
my mate gave me an old rm machine his mum got from her school, who were going to skip them anyway.
it is an old pIII beast, with an ati rage pro gfx card.
i tried overclocking, and pushed it from 450 to 623. it got quite hot, but i could still keep my finger on the heatsink. speedfasn does not work properly on the comp, as it shows its only temp reading as -199C
if i pushed it too far, what do pIII's do? will it just turn off, and probably be damaged, or will it actually catch fire? my parents are worried it may burn down the house.
thanks in advance
