Let's face it, the majority of ET6 versions are complete s**t. I had to go through about 6 versions before I found one that worked on my Extreme, issues ranged from setting ram to default voltage every time I clicked 'set', hanging, not loading at all and the usual GFX driver issues. It's really handy when it works, but the version they have on their site for the extreme didn't work at all (b10.xxxx), ended up on B9.xxxx. Would rather use speedfan anyday - less resources, better presentation of temps etc, if only it could tune voltages!
