Im using the slayher 1100 on mine and it works great. I tried Rzrs 1100 kernal but DAMN my battery life was BAD!! I had to recharge my phone through out the day and I don't use it alot.
phone sold at 550 , i can clock mine at 1200 not much of problem but will get hot when using radio alot. but thats a 100% over clock with passive cooling.
im sure i cant clock my 3.2 i7 to 6.4 even with water cooling
i was talking speed. but that shows how the voltages set are a big differnce. i also have to run the 1200 kernel to have good funtion but i down clock it to 900 if i run the 900 kernel i will get reboots.
Dont forget with sourcery you can make your own kernel and set all the defaults. still currently the only rom to have such a feature built in. and only automated process at that.
