How to Overclock to1.2G

---

Here is the method to OC 1.2G

- move to arch/arm/plat-s5pc11x and change next three files
: max8998+consumer.c, s5pc110-dvfs.c, s5pc110-clock.c

- And, change some parameters like,
1000000 --> 1200000
250 --> 300
1250 --> 1300

<in file max8998+consumer.c>
/* frequency, Mathced VDD ARM voltage , Matched VDD INT*/
#if 1
{1200000, 1300, 1100, 0},

static const unsigned int dvs_arm_voltage_set[][2] = {
{DVSARM1, 1300},

<in file s5pc110-dvfs.c>
/* frequency */
static struct cpufreq_frequency_table s5pc110_freq_table_1GHZ[] = {
{L0, 1200*1000},

<in file s5pc110-clock.c>
/*APLL_FOUT, MPLL_FOUT, ARMCLK, HCLK_DSYS*/
static const u32 s5p_sysout_clk_tab_1GHZ[][4] = {
// APLL:1000,ARMCLK:1000,HCLK_MSYS:200,MPLL:667,HCLK_ DSYS:166,HCLK_PSYS:133,PCLK_MSYS:100,PCLK_DSYS:83, PCLK_PSYS:66
{1200* MHZ, 667 *MHZ, 1200 *MHZ, 166 *MHZ},

/*pms value table*/
/*APLL(m, p, s), MPLL(m, p, s)*/
static const u32 s5p_sys_clk_mps_tab_1GHZ[][6] = {
{300, 6, 1, 667, 12, 1},

Then compile to zImage and flash it with ODIN.
I will not upload my zImage file because it's for M110S.

If someone find best rates and ARM voltage for upper clock, leave it here. :)

THANK YOU..... now just have to wait for someone smarter then me to actually do it and post the file, lol.

For best battery life and less stress to CPU someone should try to find lowest VDD which supports high frequency.

Here is one I compiled. I didn't just change the 1ghz but added a the 1.2ghz as an extra speed.

This is COMPLETELY untested. I'm not really much of a coder.
This MAY brick your device. If you know how to unbrick a SGS that has been flashed with a bad kernel, then you can try it. This is VIBRANT only (as that's the code that I had on my laptop at the time.)
I am not responsible for any damages to your phone. Please, please, please, ONLY flash this if you know how to recover from a bad kernel.

ONLY CLICK HERE IF YOU READ AND AGREED WITH THE WARNING IN RED!!!

Why the hell would anyone want to overclock their phone?

If you just want to destroy the phone, dont do it. donate it instead.

Wonderful
I really miss the custum oc and undervolt kernels from my Nexus.
Good work !

who tells you the phone would be destroyed from OC? sure it really needs to be tested through stress tests and the first people to try will be endangered to brick, but normally the cpu is failing and freezing when it gets too hot. on the i7500 we have overclocking from 528mhz to 710mhz and most of the devices run fine with that. however some devices can only be clocked to 614mhz without freezing which is due their cpus are not that good quality, but never we had any user reporting a grilled cpu. however we have to be carefully with voltages (what actually causes cpu grilling) to not raise them to much.

your kernel is only 2.6mb in size while all the stock and other kernels are about 5mb. if i compile the kernel source myself i also get only about 2.6, any idea why? missing modules in the image maybe?

thank you!

You need initramfs

actuallly im more interested in saving battery life by underclocking and undervolting the phone. Is it possible also?

Or at least remain at 1Ghz but with voltage lowered.

If anyone found the best combination please share
