Ok download this zip an flash in cwm
http://opptimizer.googlecode.com/files/mo_simp_1.5_edison-signed.zip
Then download rom tool box an set the max cpu speed at 800 mhz
Then open the rom tool box scripter (u will be making 2 scripts)
First script. Make sure they are spaced as u see in the post do not put them all on one line so u will put in.
insmod /system/lib/modules/symsearch.ko
insmod /system/lib/modules/overclock.ko
Second script u will put in.
echo 3 1300000000 63 > /proc/overclock/mpu_opps
echo 384000000 > /proc/overclock/gpu_opps
Then will run the first script u made if it fails just ignore it its only there to make sure the files needed have run on boot then run the second script an then ur done ur gpu will be overclocked an ur cpu will be overclocked to 1300 mhz u can also edit the second script if u want to go higher or lower but don't select the set at boot option in the rom tool box scripter till u have found a stable setting
