"Try setting your OC to 480 min, 600 max, with your governor to SmartassV2; others may work fine, but this one seems to work for a lot of people who've posted in this thread. If that cuts down your restarts, you can try more adventurous with lower or higher settings. If your phone is anything like mine, though, it will be unhappy with anything else."
I'm trying this now. How much does this hurt battery life? If it hurts it severely I'll just switch back to Harmonia 2.0 for the time being, which had been working fine for me...
