I made a small bin file for those not sure how to apply oc setting via cgminer.sh.
The bin file is loaded via the upgrade tab in miner administration just like you would upload a firmware. On reboot the modification will be gone again and bin file will have to be uploaded again in order to apply oc setting.
The bin file contains a folder with two files:
runme.sh
#!/bin/sh
cp cgminer.sh /etc/init.d/cgminer.sh
echo "900MHz OC setting copied! Please go back to Miner Settings page and Restart Miner <b>without rebooting</b> by <a href=\"/miner_setting.html\">clicking here</a>."

runme.sh will copy a modified version of cgminer.sh set for 900MHz to /etc/init.d/ overwriting the original cgminer.sh
After uploading the bin file, you need to go to the mining tab in administration and pick Restart Miner in order to apply setting.
Content of bin file can be examined and modified using e.g. 7zip
Other oc settings are listed in the modified cgminer.sh like:
# cmd=$(printf "0x86,0x%02X,0x02,0x01" $c)
# cmd=$(printf "0x86,0x%02X,0x02,0x11" $c)
# cmd=$(printf "0x86,0x%02X,0x02,0x21" $c)
cmd=$(printf "0x86,0x%02X,0x02,0x31" $c)
# cmd=$(printf "0x86,0x%02X,0x02,0x41" $c)
# cmd=$(printf "0x86,0x%02X,0x02,0x51" $c)
# are disabled settings
Active setting is 231 which corresponds to 900MHz:
cmd=$(printf "0x86,0x%02X,0x02,0x31" $c)
Lowest disabled setting is 201 which corresponds to 825MHz:
# cmd=$(printf "0x86,0x%02X,0x02,0x01" $c)
Highest disabled setting is 251 which corresponds to 950MHz:
# cmd=$(printf "0x86,0x%02X,0x02,0x51" $c)
If you wish to go beyond these ranges, then look up the list of settings posted in various threads here.
Applying any other setting than the active 231 setting require that you modify the cgminer.sh in the bin file.
I take no responsibility for any damage due to oc if such should occur. The 231 setting is quite safe if you have proper cooling, but you will probably need to adjust die voltages to match the higher asic frequency.
Any changes made to voltages in Advanced Settings, will reset frequency to stock default setting and you will have to pick Restart Miner in the Mining tab in order to reapply oc settings.
