I have been running 1350Mhz without any voltage tweaks for 1week.
I used your old version which required opensh etc. Now i downloaded your GUI version and it's very nice. However now i realized that my phone can go up to 1400mhz with little added voltage, and it's completely stable atleast in PS1 emulation with Emumaster.

However i still can't run some games at stable 60fps (bouncing at 50-57), so can you please add ability to overclock further than 1400mhz, or tell me the commands again to do it from opensh
