"Go look at my heroc commits for the heroc on github.com. I've added my latest oc source there. Also for setcpu u need to use custom settings and make a setcpu.txt and put it on ur sdcard. I've gotten the heroc stable at 768mhz with that code and if u use setcpu u can adjust ur min and max freq to whatever u want. To save battery or get awesome fps in games. My current code scales really well and is much nicer then mine and phhussons first oc patch."
this appearently works on the eris as he posted it on the eris forum, only problem is i cant seem to find what he is talking about on github.
if someone can give clearer instructions on how to get to the code thatd be awesome
