don't use EasyTune... its terrible, bios oc's are the best because they are stable and directly oc the CPU... when you startup your PC, the OC will be applied, with EasyTune its tied to the program/windows
anyways, overclock until you reach ~70C
amd is wrong... theres no point in not overclocking if you below ~70C... unless you need to use crazy volts (1.6+ since it lowers your CPU's life span by a lot)
