EDIT: Perflock really doesnt allow the settings to stick. Sure you can change them in Set CPU or a similar app, but after using CPU Spy and realizing that the phone does not clock to above 1.5GHZ unless Set CPU is open this is considered pretty much useless until a custom kernel comes that disables perflock. Sorry.

First I want to say thanks to Haus for showing me how to do this, his thread is here. This is not my own release but rather I modded coolbho3000's original module to work with our phones. The rest of the post will be word for word verbatim of his post.

Instructions

Install the overclock (only once):
1. Push the kernel module to your device, make sure it is the krait_oc.ko file, not the krait_oc.ko.bak file:
Code:
adb push krait_oc.ko /data/local
2. Install the new thermald.conf, making sure to back up the old one, and reboot. The thermald.conf is included in the download. If you want to target a frequency other than 1809000 KHz, you should edit the thermald.conf and replace "1809000" to whatever frequency you want to target.
Code:
adb push thermald.conf /data/local
adb shell
su
mount -o rw,remount /system
cp /system/etc/thermald.conf /system/etc/thermald.conf.bak
rm -r /system/etc/thermald.conf
cp /data/local/thermald.conf /system/etc
reboot
Load the overclock (every time you reboot):
1. Load the kernel module (replace pll_l_val and vdd_uv with your desired voltages and L value as explained above. It defaults to 67 and 1300000 if you don't give it any parameters):
Code:
adb shell
su
insmod /data/local/krait_oc.ko pll_l_val=67 vdd_uv=1300000
2. Bring core 1 temporarily offline so it gets updated with the new max frequency:
Code:
echo 0 > /sys/devices/system/cpu/cpu1/online
3. You'll now have an additional CPU frequency! SetCPU can configure your maximum frequency up to this speed. You can also choose to keep running at 1.5GHz at any time - this method doesn't eliminate any available frequencies. Set the max at 1.8GHz to verify it's stable here.
4. Restart thermald by running "ps". Look for "thermald" in the list, and find thermald's pid (it's usually a number in the low hundreds, higher up in the list). Run "kill [thermald's PID]" in adb shell. The kernel does not currently have kernel-level temperature throttling turned on, so thermald is important for now.

Remove the overclock by restoring your backup of thermald.conf:
Code:
adb shell
su
mount -o rw,remount /system
rm -r /system/etc/thermald.conf
cp /system/etc/thermald.conf.bak /system/etc/thermald.conf
rm -r /system/etc/thermald.conf.bak
reboot
Rebooting clears any kernel modules that are loaded, so you're now clean. You can then delete anything left over in /data/local, but it doesn't matter.

This is amazing. We can overclock before kernel source drops... Thank you devs once again for exceeding my expectations!

Seems a little complicated for me but can't wait to see how this thing does oc'd so we know what to expect when Kernel source is released ..
