try this

current kernel configuration:
current frequency: 900
supported frequencies: 125 250 500 550 600 720 805 850 900 950 1000 1100 1150
min. frequency: "blank"
max. frequency: 900
avoid frequencies:
active frequencies: 125:30,90 250:38,180 500:30,360 550:33,400 600:38,430 720:45,430 805:48,430 850:48,500 900:72,520 950:54,500 1000:60,500 1100:72,520 1150:72,520
SmartReflex VDD1=1, VDD2=1

this is my kernel configuration :
# minimum frequency to use
MINFREQ=125
# maximum frequency to use
MAXFREQ=1150
# list of frequency configurations: each "frequency:volt,dsprate"
FREQS="0:30,90 125:12,90 250:25,180 500:40,360 550:54,400 600:60,430 720:60,520 805:60,600 850:60,600 900:60,600 950:60,600 1000:60,600 1100:72,600 1150:72,600"
SMARTREFLEX_VDD1=0
SMARTREFLEX_VDD2=1
GOVERNOR=ondemand
UP_THRESHOLD=95
SAMPLING_RATE=300000
IGNORE_NICE_LOAD=1
POWERSAVE_BIAS=0

fells like new phone , the downside :the battery goes faster , use of messenger(wi-fi) +some photos +some calls , 2 days isn't bad

whats the point of overclock when you got call it goes to 600
and you have to load your configuraton file ( you have to do this everytime you got a call)

are sure you have 2 days with this configuration or ist 600?

Only during the call the frequencies are set to the default value, afterwards kernel-power takes over to readjust the profile.

There's no point lowering the minimum frequency in this instance.
The minimum clock is "0".

Also your voltages per frequency are really high.
Plus you should have both VDD 1 & 2 off with custom voltages.

Personally I don't overclock at all, I think you will be best to use default settings, smartreflex at 250-805 (This is the new better way to overclock). 1150Mhz is asking for a brick.

Please also note starving / undervoltaging too much may cause corruption.

is this normal? i have set the default for 500mhz and 1150mhz, but about a minute later it goes to 500mhz/850mhz. i read somewhere that you had to edit a file if you have kernel-power, but can't remember which file. thanks
