I think when I did this I was using quickclock advanced at
333
641
922
1200-1300 (I don't remember)
Quadrant score: 2510
My phone crashed when I tried to push it up past 1350.
The way I got it to there was just playing with the numbers. For the low end, these number work really well for my phone, and the upper end I just kept pushing it starting at 1100 up by the 30s and then when I got up near 1250ish I starting going up by 20s until my phone crashed. My sole goal was to see how high I could get it. As of right now I'm running
321Mhz, 20 vsel
641Mhz, 36 vsel
922Mhz, 50 vsel
1130Mhz, 60 vsel
My quadrant score is: 1793. If I pump it up 100 Mhz at the top end to 1230, I get a score of: 2259
It really depends on the phone.
BTW I got the phone on the first release, and I'm running Liberty 1.5 with Draya's Black Gingerbread theme. Feel free to PM me with any questions!
