use chevy 0.8 ghz lv kernel and its fast. The slots are awesome. Battery life was great today, although I didnt use my phone much while working. I had 18 hours use and 40 percent charge left. It has seemed to help some since the 7 slots are 125, 250, 400, 550, 600, 700, 800
I o/c to 800 for regular use, which is as high as I go. There is no performance difference for my phone in running it higher...so I see no point in it other than to say "hey I got a 1400+ quadrant" Which...not to get into it, but...is not a valid way to judge performance. My typical qs is 1050-1100 oc to 800 mhz. My phone performs extremely well, and I dont care for the heat that comes with higher speeds (and my phone freezes at anything higher than 1.0 ghz...so I see no need to push it to its limit everyday)
I use all the slots except the 250 using set cpu and profiles.
I like chevy kernel due to the temp monitoring in setcpu. And chevy kernels are awesome (as is his roms for that matter.)
