Im trying to o/c my x1600xt with ati tool .25 beta 13, when i choose find max care, the gpu screams up to 100C and cpu up to the 80's at only 600Mhz, it always says fan speed at 100%. What is safe as far as temperatures go for both cpu and gpu,do these work correct on ati tool. Btw, im using stock cooling on everything. Any help would be appreciated,as well if anyone has an idea of how far i should push the cork and mem on stock cooling.
