I know have my V4b, 128ram, 2.01voltage amd k6-II+ processor stable (for the most part) at 450mhz. The only problem know is when the video is trying to load a picture above ~2mg it will back screen. Everything else continues to work. My question is this a current draw problem or simply a problem caused by the limitted 2mg video? I have ran at 500mhz, but have not determined if the problem that I am having at 450 is the same one(s) at 500. On my V1, 64ram, 2.1voltage, amd k6-III 450mhz, it runs rock solid, but at 500 almost always does the continual rebooting thing. I can live very happily with my V1 at 450, but would like to have my V4 running at 500 or above. Would dropping the voltage on my v4 help? Any suggestions? Thanks.
