1st (bricked return): one under max (840? stable)
2nd (gf's): 840 stable as well
3rd (my current): 840, 824 stable.
Are you using a different Kernel than what you have released here?
why would I do that? i have a different ramdisk but that wouldn't affect the ability of how high your phone can OC. it just automates the OC for me without SetCPU, and some other unrelated crap.
