I keep sr on. At the voltage you are at and the mhz, the only problem I encountered was the N9 heated up too quickly. I wasn't comfortable with melting my chipset, so I brought the clock down to 1100mhz at stock voltage and things worked out.
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
So.. Is there different at the 16GB or 64GB version?
My 64 working very good and not warming at all in 1300MHz/1337500 voltage. I use Faster N9 too. It is awesome! I don't even wait PR1.3 anymore
