Everyone should be aware that your device is different than mine. Two devices with the exact same ROM, settings, SD Card, apps could max OC at two completely different speeds.
I am able to get to 786 without any issues both on stock and the latest NRG ROM, there are a lucky few that are able to achieve 806
The best advice I can give you is start low, and work your way up
If you think you have found your max speed, here is the best test I have found to verify stability...
- Open a text message
- Flip open your keyboard and start typing,
- If you lock up you need to drop the speed a level and try again!
