Extra 2V would have killed it, you gave it an extra .2V lol
1.55V is rather high, mine is stable with 1.475V.
If your machine will withstand a couple of hours of Prime95, you’re doing good. If it’ll run over night, it’s bullet resistant. If it’ll run overnight in the middle of the summer, in an 80 degree room, well, you really have something to brag about."
