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.
a few FPS drops here and there, but hey, it's 100 watchable now

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.

Let us know how this works for you.
If your phone starts getting hot pull the battery.

phone went from 966 to 1212 on the quadrant score with a stock rom.

Works great getting scores around 12300 on quadrent using shadowman's v2.2

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.

I highly recommend Calkulin+Clemsyn OC/UV kernel (1.5 ghz) rom

So, after people started reporting that their benchmarks are in the 3000's, I decided to flash from ginger RC1 and holy cow this is freakin' fast. Even before I ran the quadrant test everything felt so fast. Twice as fast as vegan gingerbread. I wanted to run the quadrant with all the apps and stuff that I'd be running (quickoffice, dolphin, etc.) and holy cow benchmark was still in the 3000's every time.
I ain't moving to any other rom until someone finds something faster.

Does the unit feel warm or hot ? The rated CPU clock speed is 1.2 (or 1.0, not sure). I am a bit concerned about overclocking to 1.5 at higher voltage. In addition, what apps that were slow and are needing this kind of power ?
Thanks

Sweet.. but honestly with out video drivers for gingerbread its utterly pointless for me :O( Keep us updated on how stable it is :O)

Since when did we "need" anything? The gtab will work just fine with the stock rom. But with a custom rom, it works better. The clakulin+clemsyn v3 combo works even better. I just like the raw power that it gives me.
Added by edit.
But to answer your questions, doesn't feel warm or hot to me at all. Battery life is undoubtedly reduced, although I'm still trying to determine by how much. Stand by for this.

I was concerned about heat and the case feels a bit warmer but not significantly. I guess we will see over time. I would say battery life is reduced but I don't have any numbers. The devs have included a nifty OC profile based on battery life. This is my new favorite rom.

This combo is crazy fast. I scored a 3521 on quadrant. I have been running it for 24 hrs now with no issues. Does not seem to be running hot at all. Battery life seems fine but Im sure it is using more juice.

Here. Nuff said.
Edit.
Keep in mind that I've already installed apps like quickoffice and such. In other words, if I had ran this test right after I flashed this rom I'm sure the score would have been higher.

Here you go: 4484, that beats 345 xooms even overclocked . Oh my.
Sorry about the resolution. I didn't know if I posted at full size if the picture would be huge or not.

How the flying pigs did you get it up to 4484?

Ok, so I ran it a few more times and it seemed a little sluggish as I had been putting it through its paces today . I shut it down and rebooted. I just ran it 3 times in a row. My lowest score after letting it sit for a bit was 4521, best of the 3 was 4665! Yikes.

I am also using and loving this rom. Love the smooth video with Froyo (but wish it could work with Ginger).
It feels slightly warmer than before I think, but the temp sensor never reads above 87 degrees F, which has to be a safe operating temp, right?
Consistently getting ~3500 quadrants with many apps.

Listen to me very carefully. The devs are doing this on their own time without getting paid. Us lowly humans don't wish anything. Ok? Clemsyn said he was going to do ginger soon, and that's his choice. We don't wish anything. Ok? He's not obligated to do anything. What he's done for froyo is way way way beyond what he's suppose to do, which is nothing. Ok? He made it clear just last week that his intention was to return the gtab and move on with his life. He then decided to stick around and created new roms that are almost twice as fast as previous roms.
If you're disappointed, then Clemsyn could just drop the whole thing and leave. If you're disappointed, please go buy an ipad 2, ok?
In fact, I highly recommend against getting a gtab for most people. I promise, you will not be disappointed with the ipad 2. Love you long time. Go, put the disappointment of a device gtab up on ebay and go out and buy the ipad 2 now, please, before you get any more disappointed.

Very nice. Xoom owners will hate you for sure.
Thank you and others for posting scores.

Very fast. Always loved Calkulin's ROM, and I've come home after playing with Vegan GB for a while (also a great ROM). It also appears that the OC settings work with pershoot's OC kernel as well. I love the fact that it clocks based on battery life.

@goodintentions
Geez guy, did you wake up on the wrong side of the bed this morning? It's not like he posted a long harrasing write up for Gingerbread. It was subtle just like you should be. Chill out please.
On that note does anyone have a video of this "Beast ROM" in action?

Wish I could get this combo running. I have been running C&C 1.1+v9 for awhile now and love it. I can't get any of the OC kernals running. The only way I can get this to boot is to install the C&C OC combo and before booting I have to install Clemsyn's v9 kernal. I can't get Pershoots 1.4 ghz kernel running either.
The best I have gotten was with the C&C combo and then installing Clemsyn's OC Extra kernal and I can get to the HC animated boot screen but it never gets past that. My son and I bought our gtabs the same day and his runs all the OC kernels.. Oh Well...

[Q] Tiamat Kernel Question

I have been looking for a couple of days, and I can't seem to find my answer anywhere. Sorry if this question has already been asked. Does the Tiamat Kernel come overclock already, or do you need to use an app like SetCPU?

SetCPU is needed

Thank Brenardo.
I really want to root so i can get the USB host, and SD card. I just didn't want the overclock. I was told that Tiamat was overclock from the get go.

even without an OC app running my CPU sometimes runs up to 1504mhz. I've tried every kernel since the first tiamat one. I have a Canadian xoom rooted with one click. I'm using tiamat 1.4.1 and the issue isn't fixed. I've read many others experiencing the same issue. I've tried using setcpu and Droid OC to limit it to 1ghz but it still hits 1504. There both uninstalled now but I'm still having spikes. Just my 2 cents not trying to hyjack your thread. But if anyone has any input as to whats happening I'd appreciate it.
Also my battery life is significantly shorter since rooting. From about 9 hours to 4 now.
Any suggestions ?

How are you seeing its over with no app? I'm not calling you a liar, just trying to get all the facts. In all test we have done, even with the setcpu oc to 1.5/1.5, we actually see the cpu running at 1 ghz after a wakeup.

I'm watching the temp+CPU widget to monitor what's happening. Are you suggesting its giving inaccurate readings? Setcpu at 1ghz would still show random spikes to 1504mhz. I don't have any OC tools installed right now but my widget still shows it hitting 1504 especially under load. I was thinking of returning to stock and rooting manually but it not a huge problem just strange. I was hoping the new kernel would fix it but its still happening. Is there anything I can do besides start from scratch?

Yea setcpu is not 100% yet. Does your widget show both cpus? What we were testing was the second CPU. After you xoom goes to sleep, the second CPU is never set again by setcpu (known bug). So lets say you are running 1.0/1.5. After you xoom goes to sleep you will wake up with cpu 0 at a max of 1.5, but cpu 1 will have a max of 1.0. The info i gave earlier was said wrong. I was actually looking at the wrong line, so you may in fact be correct on the 1.5ghz random jump . Gonna stop talking now, as we are hyjacking someone else's thread .
In theory, you should not need overclocking software, as the max is set at 1ghz on both cpus. But as said above by Bandit504, this may NOT be the case .

Thanks bwcorvus and Bandit504 . So I guess to call it is safe, it would be good idea to use SetCPU, or Droid Overclock and have the maximum set to 1 ghz, to keep the proc from hitting the 1.5 ghz speed. I just hate to ruin the hardware with the overclock, and have to drop another $600 for another xoom.

Whats your CPU Profiles!

So I have...
My G2x Is running at 1gz\.4 I don't find a need to OV it...
The UV is set at -50 at 1gz and at 800 it is -100 and at 500 and 400 at -200mv.
What are your sets? I would like to see other people's choices. I will report on my battery life later. I can't today since I have been going into recovery mode all morning.
Ps. As profiles go...
I have screen off set to 800/400. I don't like it lagging when i turn my screen on.
I can run stress test easily with my settings. No hiccups or anything.
EDIT:
So I was asked what kernel I'm using... I will post my ROM + KErnel! and just to let you know, my G2x has never had any problems so that may be way my G2x can get -200 on 500 and 400

How are you not getting reboot problems with 400 at -200mv? I'm using faux's froyo kernel and when I undervolt at -100mv i get rebooting problems

I replied to your comment in my main post, since other people may be interested in that and that will cause them not to scan the pages.

Bump :\ I would like input

so how is your battery life?

Bad. Something about those settings messed it up. I much prefer just using the custom rom default kernel its much better on the battery

My chip could only use faux's OC 1.2ghz, using the kernel OC 1.5 would cause my phone to boot loop. I could go stable @ faux OC 1.2 with minimum UV, getting qudrant score of atleast 3000 - 3500. Another kernel that i tried is MOrfic's, I can go stable up to 1.4 Ghz/minimum UV- quadrant of atleast 4000-4300. I believe i have what they say as the "weak chip" though running OC @ 1.4 ghz doesn't make it look weak. Thanks to the great DevS!

[INFO] Achieving good battery life!!

I want to share my setup with you guys for getting good battery life which lasts the day without making you compromise on the features. The primary things I've seen on the forums so far has a lot of involved setup and frankly by the time you get it perfect, you will flash a new ROM and have to re-do a lot of it and so on, overall it's not the worth the hassle.
This is usually what my days look like and I manage to last the entire day:
I keep wifi and GPS on always, regardless of whether I'm using it or not.
Get a fair bit of calls because I live away from family so they all call a lot (I have a massive family, so we are talking about 5-6 hrs of talking everyday).
I like to read news from news republic and I'm subscribed to a lot of stuff there so I go through like 2000+ articles in a given day.
XDA like every few hrs (damn ICS!).
Text messages are also flowing throughout the day with the woman being on the other side of the country and all (100+ a day?).
I have facebook on push (not an addict but active enough to mention)
My gmail, school and exchange are all on push for email so they I see a fair bit there
The setup is VERY easy to setup and replicate. It doesn't require you to lose out on features or use your phone at an anorexic level either. You don't need a task manager or watch your processor non-stop either.
So without further delay, here we go:
Pick a ROM
I'm using Seanster_GBaxe EX v1.5.1 from the T-Mobile section, you can find it here.
Get faux's kernel
The reason for this particular one is because it's given the best results when it comes to undervolting and overclocking without SOD. You can find the kernel here.
Get System Tuner
This is available on market. There are alternatives but for this post, I will be making all the references from this app.
Get the AGPS patch from crypted
This isn't for battery directly but it does get locks VERY fast and you waste less clock cycles getting the signal. Less clock cycles wasted, more battery saved. The patch is available here.
I personally use the v3.0 Google CWM Build (scroll down his post and you will see it)
Get the V6 SUPERCHARGER from zeppelinrox
This is available here. Why the beta one? It works fine.
Okay, at this point you can pretty much store these things together in a neat little folder on your SD card because it makes a perfect library. So let's get started, I'll assume that we are starting from scratch. The order for everything will be as follows:
Get into recovery and install your ROM
This I shouldn't have to explain, the instructions you can find on the ROM thread.
Install the kernel
Same with this, read the kernel thread.
Install the GPS patch
Same with this as well
Boot into ROM
Hmm.... hopefully you can manage this
Restore all your backups and apps, accounts and whatever else
Using titanium here is always good
Install System Tuner
Okay, let's get started. Although faux has done an amazing job with the kernel, there's always the personal bias that goes into making things so his balanced settings might not reflect yours (nor mine but you will be tweak even those soon).
Inside System Tuner, go to CPU:
The first you thing you should choose is whether you want to keep the 1.72 GHz OC or not. I kept it but if you want to get even more you can lower to stock 1.56 GHz or go even lower, your choice. Once you set the max, set the min to 384 MHz. Set it once and you don't need to do it again after. Leave the governer to ONDEMAND.
Now go to the Voltage tab:
Be careful here, this can crash you if you go too far. What we do here is globally undervolt, you can do that by hitting the -12.5 mV button over and over. I use -75 mV (press the button 6 times, for those bad at math). Keep in mind that all chips are NOT THE SAME!!! -75 mV might be too much for you or you might even be able to get to -100 mV, find out by doing it.
Now go back to the CPU tab and hit Boot Settings:
Hit Screen-off behavior:
Governor - No changes
Max frequency - 384 MHz (push doesn't lag at all still so don't worry about notifications)
Max frequency/in call - 384 MHz (yes, calls don't require full blast, they work fine even under 500 MHz)
Now go back
Hit Governors behavior:
Sampling rate - Unchanged (faux has it done perfect)
Up-threshold - 75 (what's this? This means that the CPU will scale to higher frequencies when the load is above 75%)
Power-save Bias - 70 (what's this? This means that the CPU will be "biased" towards lower frequencies when load is below 70%)
Setting the Power-save Bias higher than the Up-threshold is obviously stupid so make sure you did it right.
Now go back
At the bottom, there is a whole bunch of tweaks:
Hit Re-apply CPU settings, choose init.d script (you can choose boot too but init.d works 100% of the time)
Hit Boost app loading, choose init.d
Hit Clear cache, choose init.d
Now go back
Find the Startups section and disable whatever you don't want running at boot (this is purely a personal thing).
Install V6 script
His instructions are very good so I'll assume that you have gotten it installed. Once you have it running, choose option 9, the 1000 HP one. Reboot. Run script again, make sure you've got it at 100% supercharged. Done. Reboot just to be sure again.
All done! Now, I know that was lengthy but here's the awesome part. Make a titanium full backup of System Tuner and you NEVER have to do that again for ANY ROM as long as you use the same kernel!! The script is unfortunately the only thing you have to re-apply, probably that has a quick setup too but I'm new to it so I can't give you shortcuts on it.
Hope you have luck with this and it works for you. I promise nothing and if you break your phone please don't come crying to me because you chose to do this yourself. It works for me so I shared it!! Any suggestions are welcome of course.
Note: NO task manager required!! I will modify this for cm7 if needed.

nice job. thanks a lot!

You're using the rc6.1 correct?

Thanks for the detailed write-up.
Are you in an LTE market? A full day on LTE would be pretty awesome.
For the screen-off behavior, do you think one can get away with using the smartass governor instead?

I'm using the RC6, tad older I guess.

I'm not in LTE area :-(... Would be nice because that's why I got the phone but then I had to move so can't say anything about LTE.
As for smartass, what kernel are you using? Smartass works very similar to the modified ondemand settings that I set up so it wouldn't make a difference as far as I forsee.

I tried this, will post results later. Thanks for the great tutorial

If you could post screen shots of your CPU Spy that would be helpful! How well does your phone do on going into deep sleep? On average from what to what time does yours last you? I'm just skeptical about setting the screen off behavior cause that usually prevents the phone from going to Deep Sleep.

You're right about the deep sleep, don't let it go into deep sleep. It lasts me 12 hours normally. I'll get you screenshots when I get a chance.

Mine goes into deep sleep with screen off behavior setup.

Dont you think the phone waste alot more battery though when it doesn't go into deep sleep? I've also found that WiFi tends to create a nasty wake lock. My set up is Sky ICS Speed with Faux Clock 1.296 ghz max -384 mhz min. -37.5 u/v LTE on all day, extremely heavy usage. 12 hour battery life on average.

From what I've noticed with the faux kernel, it goes into deep sleep after some time on it's own, regardless of the screen-off behavior. I haven't opened up the source to check it out for a better explanation but that's something I doubt is worth exploring since the performance doesn't take any hit.
I haven't chosen to underclock to 1.2 but it should do better than the 12 hrs I get now if I did do that. I have a tendency to start GTA 3 and start playing whenever I get bored so that's why I went OC rather than under. For others looking strictly to use the phone with minimal gaming, this would be a good option. LTE isn't available in my area so I can't test with it but the WiFi radio uses just as much battery as the LTE, if not more I have a feeling.
Trying eugene's kernel from today to see if the lionheart governor does better than the current setup. I will know in a couple of days because every ROM flash needs a couple of charge cycles before it accurately shows battery status.

Do you get any SOD? Everything working okay? Is the setup different than what I've got up there? Would like to know and try it out, can update the OP accordingly.

Just finished with eugene's kernel and the results were pretty disappointing. Looks like the second core is always kept on regardless, faux's kernel turns the second core offline until usage demands need it.
If anyone knows how to tweak eugene's to stop that from happening, do share.

Can you clue me location of his latest ROM? Or is it somewhere in the Macnut thread on TMO side of the fence?

Using darkside ROM at the moment with the faux kernel, had the Eugene kernel but I noticed that the second core is kept alive regardless of usage and that wasn't helping so I changed back to faux.

thanks for the awesome write up!
Did it last night, and lasted the day without a sweat! However, my min frequency wont stick? I have it set to stock frequency 1.5, using faux kernal, and my voltages arent as low as yours (im not a crazy user like you.. maybe an hour of talking a day, lots of texts and emails tho), but i cannot get my min frequency of 3xx to stay. Suggestions?
Thanks!
edit- running stockMod v1.0

im sorry, i have a hard time believing you talk for 6 hours and scroll thry 2000 pages of web and get a day of use. I myself could get about 1.5 days on battery strictly by staying home, connected to wifi all day and barely talking on the phone. i would like to see a screenshot of battery usage at the end of your day
