I tried to overclock amd k6 3d 400 to 550 with 2.2 volts it won"t boot to w98. If I change it to 2.3 it boots to w98 but gets explorer error. Haven"t tried any higher volts. Just running a clobewin cpu fan and extra case fan on GA 5AX board. Does anyone think it will hurt to go up any higher on voltage?
