that is a perfectly fine temperature
and Alex got a lucky chip, mine unlocks but i could only get it up to 3.5 with 1.55v, i have lower temps though
(around 45c)
I am thinking I might see if i could go higher but I dont want to fry the chip, what is the max voltage i can have on this chip?(I know i should make my own thread i may but the idea just dawned on me)
