HowTo overclock to 1.3Ghz (Samsung Galaxy S 4G)

1) SetCPU profile to 1000Mhz = temp > 43C
2) Tegrak overclock
a) load module
b) load 1100Mhz
c) Save profile in SetCPU
(REPEAT PROCESS With 1200Mhz, 1300Mhz)
Please use Set CPU and make sure to add profiles.
800 Mhz = temp > 45C (audible alarm)
1000 Mhz = temp > 43C
1100 Mhz = temp > 40C
1200 Mhz = temp > 35C
1300 Mhz = temp > 30C
My FLOPS in the stress test went from 12 to 16
Now I am able to watch Jimmy Fallon Live and probably Jersey Shore
Those Adobe Flash videos were too heavy for my 1000 Mhz processor
with 1200 Mhz, I'm happy to say the video runs nice.

I've read that a program called tegrak overclock can allow you to overclock, but from what I know unless you have an overclocked kernel, you can't overclock
I would like to know if there is a future with this phone.
Currently there are only 2 ROMs working (one of them, the author closed the thread)
I've spent at least one month fixing all the issues of this phone, and by the looks of it it's not quite popular here in USA
I will appreciate responses, since I know that overclocking can give a HUGE boost of speed.
I am thinking in returning my phone and hopefully getting the LG 2GX (Optimus 2X)
Has anybody overclocked their Samsung Galaxy S 4G?

In the defence of the person who built the ROM your talking about, he did not close the thread... a moderator did.
overclocking is currently not an option for this device and only time will tell if it will be.
as for ROMs, Krylon360 of Team Whiskey will be developing more ROMs soon as he is waiting on getting a device to work with.
the LG looks to be a good device... has many features that are better than the sgs4g so i would think its a decent switch. but for me im waiting for july... the HTC and sgsII will be be out by that time and I can choose the cream of the crop.

Any idea when it will be released?
And what price it will have?
If the phone costs around $600, I would buy it
Anything over it I'd guess it's overpriced.
the one thing that I DO NOT LIKE about the Galaxy S 4G is the lack of Flash for the camera
I'd say for a $500 device adding a $10 flash somewhere in the phone would be a good idea

worked great..quadrant score went up also..seems alot faster..thanks alot! this shouldnt do no harm to the phone right? im new to this kind of stuff so kinda nervous.

i just flashed mine to v2.2 and did the quardrant score and it went down .. did i do something wrong? did u delete the bloatware? running anything else?

As long as u watch out for the temperatures you should be fine
Even if I break the unit I still have warranty on this
Plus I'll be returning this phone anyway
I'll test Quadrant right now

When setting Profiles,
Do you have all of them default to "Charging"?
For scaling do you have them default to "Conservative"?
Do you leave all the Min at default 100000?
Do you leave all the priorities set at default 50?

This wont work due to there is no kernel that allows OC yet for the SGS4G. Ill work on building one after i get CWM and Black Ice going for the device.

It seems to work and it's also listed as supported on the list of devices in the market. I've only used Quadrant standard so far and was getting higher benchmarks.
On another note. Can't wait to get my TW fix when you get Black Ice working on our phones.

Can you upload the presets so I can just load it please ans thanks

A few comments.
1) Some SG4G's don't like 1.3 gig. I'm finding that at 1.2 gig at a high and 200 meg at the low, it's the most stable...at least for my particular unit. Your mileage may vary.
2) I'm using the "Temp >" profiles for all the settings.
3) I suspect that the reason for why it's wonky for some and works great for others is due to the fact that there isn't a true overclock kernel for it. We're taking potluck as to whether it works or not.
-Steve

I would take a word of advice from Krylon. The Kernel that is on our phones is not set up for this to work correctly. The app may support our phone but, our kernel doesn't yet.
I wouldn't recommend doing this. Wait for a compatible Kernel. It will happen but when your phone gets hotter than it was meant to, things on the mother board get loose and you have a very expensive paper weight.
Secondly, quad scores aren't that accurate. Meaning a single piece of code can tell the quadrant app to read higher than its actually running. The phone may run a little faster but its not what it will be with VooDoo lagfix.
This phone should get a true quad score in the mid 900's stock. With the right kernel, and voodoo lag fix (ext4) this phone should get around 1750-1850. That is without overclocking at all. it will have better battery and you won't overheat your phone .

I thought that Voodoo lagfix wasn't applicable in the SG4G because of the fact that the SG4G doesn't use an abnormal file structure. Or am I wrong?

I think the only real speed difference is with the browser. My vibrant / and sgs 4g get similar quad scores when the vibrant has voodoo disabled.

[Q] Kernel suggestion for underclock

I am running Cognition 4.4.8, which will not allow OC/UC. I actually just want to UC. What recommendation would you have for a kernel compatible with Cognition 4.4.8 for Captivate that would allow me to UC?

Don't you mean oc/uv? I don't think you know what you are talking about.

Yeah its UV (undervolt). Find any kernel that allows it and is working with your ROM. Maybe ask in that thread as others could be using a custom kernel for that exact reason.
Sent from my SGH-I897 using XDA Premium App

UC is a real term, maybe he meant he wants to limit his clock speed to 800mhz. What's that called if not UC?
Although undervolting and underclocking to save battery is a waste of time. The cpu doesn't use that much battery in the first place, the screen and the modem use the most power, you want the charge to last switch to the lowest brighteness and 2g, that will give way more battery than uc/uv will.

+1 on the battery topic. Even at a high OC the battery drain is not that much worse... a little yeah but not too severe.
Also good point about UC.. wasn't thinking about that at all ..underclock what!?!?

some people falsely think that the phone runs at 1ghz all the time, when in fact it downclocks itself and ramps up clockspeed when it needs it....so unless you have an app thats using 100% CPU all the time, your phone is running around 200mhz at idle.

+1 again Although there are different governors that do different things most phone at stock will idle down to 200mhz. My phone for instance idles down to 800mhz, but thats just my prefrence

Yep, I meant OC/UV. I typed too fast for my own good!

Good points
Thanks for the message on how little battery undervolting saves. That was quite helpful. I did try the discussion board for Cognition, but no one seemed to be posting on using an alternate kernel, which is why I asked for recommendations here.

I believe Cog is KB1 based, so this kernel should work: http://forum.xda-developers.com/showthread.php?t=988805

Thanks I will certainly trie eXist's kernel.

Inspire Question

What I am wondering and before you attack me I did research this and couldn't find anything specific to the Inspire. I want to know generally what is a good speed to underclock the inspire to achieve maximum batter and before you say every device is different I'm asking for a general idea not a specific one. Also do you think that overclocking has a big impact on batter I am overclocking right now at 1.3 ghz do you think that I'll notice a difference. And I know I have to test it myself but I just want others opinion on it.

I have the same question.

FWIW, I run the OnDemand Governor and underclock at 883200 (245000 min) and don't notice a slowdown in any apps I run except angry birds (I ramp it up to 1.2 to play that). I haven't run any benchmarks or anything to see how it might improve the battery, since I really don't need to worry about it. It goes on the charger every night and I've never seen it below 50% when I plug it in.
I've been running a relatively stock DesireHD Gingerbread ROM based on the Asian WWE GB (2.37.707.3) but as of yesterday, I've been running one based on the telus GB released a few days ago (2.43.661.1). My kernel is custom based on stock HTC source for the 2.6.35.10 with OC/UV support added as hacked from the LeeDroid kernel tree. My source is here:

I'm running at my rom's default (1017mhz). Instead of underclocking, I use the conservative governor. Battery life is good, but I also haven't noticed a battery drain when overclocking (I've been up to 1228mhz). I didn't test/run it for an extended period of time (1 day), but I only noticed a slight bump in performance.
I've heard of people on my rom (GingerBeast), clocking down to 768mhz without noticeable slowdown. As you stated, it just depends on the rom.

I have my phone set at:
Max: 768000
Min: 230000
This works for me in literally all the situations.

I hope my response wasn't considered rude, but the question really is too vague to answer. If there were some magic combination of OC/UV that worked for everyone, everyone would be using it.
They say that if you ask five New Yorkers their stance on an issue, you'll get six different opinions. Similarly, five smart phone users probably have six different opinions about the best setup for their device and none will be applicable to your situation.

Yea but I wasn't asking for the perfect combination out just wanted to know what others use to get an idea of what I should set it at but clearly you don't get that

Thoughts on disabling one core when using CM7 variants

It was suggested to me that in order to prevent excessive battery drain and heat when using CM7 I should disable one of the cores. Has anyone done this? What negative impacts could doing this cause (if any)?

If anything it would increase battery drain due to all the processing being put on one single core, what I would recommend for a decrease in battery drain is different kernels with under volting options. That's what's worked best for me.

It was my perception that the older single core phones had better battery life. Do you really think it would hurt the battery?

Dual core isn't properly utilized yet so it might not be a bad idea.

What are your settings?

Most of the time when both cores are on the 2nd isn't doing anything, because the first core isn't even pushed enough to reach max. So, I feel 1 core is sufficient, I'm running 4.1.x w/ 1 core @800 and the battery and speed are fine. Although I see others running speeds of 1.2 and higher, but I barely notice the difference of the freqs. The S3 is so fast that the higher clocks are overkill IMO.

I do see a difference in battery life, which is why I prefer this setup, when we have ICS I will use both cores. But I feel cheated on Ginger so I use 1 for now, and whoever said two cores has better batt is wrong...Logically two cores use twice the voltage, that means 1 cores will save a significant amount of power. A weak dual core w/ 1 core on will have bad life, but a fast on is different.

Every boot, you can make a linux script(.sh) if you want, and then use script manager. But, I'm only testing this for comparison, I can't see the speed difference w/ 1 or 2 so I just use 1. 1 @800 core feels how fast my MT4G did when OC'd @1.4Ghz.

How long have you been running like that?

I run Faux kernel, Joe's RCU, undervolted -50mV and underclocked to 1Ghz, I can now easily make it through the day and I'm a moderate to heavy user. I'm pretty sure disabling the second core isn't necessary, and frankly, if you check out how little it's used, it probably wouldn't benefit that much anyhow.

Completely false. Just because something has voltage across it doesnt mean that it is doing anything. Voltage times current equal power. Using power uses the battery.
You guys need to SERIOUSLY change the way you make decisions. Just because something SEEMS logical to you, doesnt mean it is correct. I see alot of BAD info being pushed around here.
I have CM7 and run Fauxs kernels. I FORCE both CPUs online and run at 1.56Ghz. My standby is around 30mAH...Nuff said.
Something else is messed up. Chase facts, not fiction people.

[Q] CPU Frenquency

Knowing that the processor can run at a frequency of 800MHz, I want to ask you: the processor does not break if I put on this frequency?

Certain FC will occur.
Camera might not work too

Perhaps not. I've tested it & I had no problem.actually, it also depends on ur kernel.1 time I experienced sift brick! so to prevent such things adjust frequency around 600~760. selecting smartassv2 governer is also a good suggestion!

ready for the technically paranoid answer
Overclocking is very dangerous(As if you didn't know) its actually pushing a processor to work on a higher frequency than the one it was made to withstand.As a preferred feature if you processor came from a good company(i.e they made the parts from good quality resources) and underwent rigorous testing for stability under extreme conditions.then the chances of any problems of the processor breaking under the technically specified frequency(i.e.600Mhz) are negligible but by over clocking the risk of damage to the processor increases finally it boils down not to the rom or the kernel(though the kernel provides the software side to reduce damage:good but on the quality of your processor some people can run the processor up-to 900Mhz some died trying to reach 725Mhz finally the thing is how willing are you to take the risk.Test the conditions. check the stability of the phone of the given frequency never charge while overclocking(cause it will result in extra cycles taking place in the battery) simply said the battery might explode!
finally to answer your question yes the processor can break @ that frequency and the chances of it breaking are greater if you have overclocked a long time and if your phone is also aging(means older than a year)
