Is there any gpu overclocking app for captivate.
Sent from my SAMSUNG-SGH-I897 using XDA App
Not for the stock kernel. You would need to change to a different kernel that supports overclocking.
No, there is not a way to oc the gpu, just the cpu.

Doesn't MIUI allow this with glitch? or is it that glitch has the gpu already oc'd by default... Dont remember

I'm far from an OC expert, but kernels supporting Live OC allow you to OC the bus, which affects RAM and GPU. However, I thought that it was really just increasing RAM speeds, which in turn helped the GPU a bit since it uses the same RAM. That's why if you overclock the BUS you start getting visual artifacts: because the data was getting corrupted in RAM on it's way to the GPU.
Or I'm out in left field, which is never out of the realm of possibility.
I have no clue. I just remember reading something on glitch v13 on gpu oc and MIUI. Never tried it, don't know the theory. Was just asking couse i remember reading it xD

How do you know which kernel supports OC CPU \ GPU?
Also, I guess there are some apps which let you OC your CPU \ GPU, aren't they independent of the kernel? (I might be completely off-track here, but I had to ask)
I recently flashed OneCosmic's ICS ROM and Nushor's kernel (v3189) to my Captivate.

A custom kernel is required to OC anything. GPU over clock that is user control able requires a kernel that supports live OC.

Just to state the obvious, to overclock and undervolt the CPU.
Less power, more speed.

ic, does the CM ROM already do it or not? Since i found KOR have this feature but i can't found it mentioned in CM ROM. However I saw the setCPU reported the CPU speed is changing, seems doing what OC/UV is doing, which made me confused.
The CyanogenMod kernel is capable of overclocking. Pershoot and WildMonks and intersectraven are just different kernels that are all capable of OC and maybe UV. It usually says in the filename what its voltage is.

I have a question: why I can't overclock my SGS past 1.2 ghz. When I try to set for example 1.3 or 1.4 it freezes and I take out the battery in order to make it work again. Is there something I do wrong, is it a general problem with more SGSs? If somebody can , I really appreciate. Thanks
it is a kernel thing.
the kernel has to support those frequencies.
Sent from my GT-I9000 using XDA Premium App
I tried with tegrak overclocking with voodoo kernel (the application itself doesn't need a kernal that supports those frequencies) and with Supe Optimized Kernel (1.4 ghz) and voltage control and setcpu and is the same result:freezing.
Not every cpu is capable of stable overclocking past a certain threshold. You have probably hit the max speed your cpu can maintain.
I agree with you but then why there are other people with the same phone as me that can overclock them at 1.4 ghz?
With CM7 or miui and either bilboa or zacharius kernel you can overclock to 1300 but I haven't found a kernel that allows 1400 either, I think those that are doing it are hacking the CPU settings themselves.
My phone gets really hot at 1300 running apps like dungeon defender so 1400 might just be a bit too much

I am using Darky's 9.3 ROM but my problem is that i can't even touch 1300 mhz because my phone freezes.
Maybe a dumb question, but, do you overvolt as well as overclock? Maybe the cpu isnt getting enough juice?

+1... not sure if there is much benefit at all to undervolting.. it just seems to make it immediately less stable...
can someone shed some light?
I've seen someone test this on another forum somewhere, and the difference the undervolting makes to the battery length is negligible..

The principles of ovetclocking a PC also aplly to phones. Undervolting reduces the power available to the CPU. Undervolt a little and you'll save a little power. Undervolt.too much and the CPU won't get enough power to do basic functions hence freezing.
Every CPU has a limit to which you can over clock. You can overvolt to a point but then then the CPU reaches its limit.
From what I understand (read in another post) the hummingbird processors are not suited to overclocking. Where the arm such as that in the Motorola milestone clock really well. (You can oc a 600mhz milestone to 1ghz before you start seeing instability)
Hope this helped.

I understand the intention of undervolting as i am pretty good with PCs. Got my good old i7 overclocked constantly. But undervolting on the SGS has yet to show me any definitive advantages.

You cannot overclock just any Note kernel. Some don't support overclocking (like Franco), some do (like Abyss).
use odin to flash a kernel like CF or FM, after that your note will toot. Then install app like setcpu . You can overclock to 1.7GHz the Max. Enjoy your GSN !

max frequency depends on kernel. You can overclock with programs like setcpu, tegrak overclock, system tuner pro and etc. But your phone must be rooted
Abyss can go up to 1704Mhz

Once overclocked, I recommend trying a speed test app at the speed you want. If I try at 1700, it freezes, at least if it was warm to begin. At 1600 it seems OK.
Each chip is different, but this method will let you gauge the abilities of your processor. Keeping below any speed that causes problem under load will help prevent CPU damage.

Dont forget "voltage control" thats a good one.
Overclocking will decrease the lifespan of a processor. For example intel processors easily work a fifteen year lifespan on stock values. On overclocked values this may decrease to five to ten years as not all processors are created equal. I wouldn't worry about it, i doubt you'll even be carrying the same phone after say, three years.
Hi guys, some times ago I flashed Semaphore, but it haven't any CPU step higher than 1000 MHz. Can I have more CPU steps,like Devil, in Semaphore? (100-1400 MHz)
(Sorry for my bad english)
Download Semaphore Manager from the market. You can overclock using that app. Mind you, semaphore kernel can get glitchy at ~114% OC and up, so you might want to go with 110 and build gradually until you find a sweet spot...

Heh, mine caps at 108%. It would be nice to "normally" oc to 1200mHz on semaphore. I could get 1296mHz with 108% like on Devil.

the "live oc" has better performance of "simple oc" (at equal overclocking), because "live oc" overclock all frequencies and not only the higher frequency.
But with "live oc" you can raise less the frequencies

The only limit is your device. If your CPU/GPU doesn't like OC - you have to live with it (or buy another I9000 :cyclops: )

Theoretically yes, but if you overclock BUS, your CPU, GPU, and RAM are OC'ed. On stock BUS is clocked at 200mHz. If you use LiveOC 110%, you overclock everything by 10% - GPU goes from 200mHz -> 220mHz, CPU from 1000mHz -> 1100mHz. That's why it's more unstable than normal OC.

You might be able to get a higher stable overclock with voltage increase; available in later versions of semaphore, but that's something you'd need some guidance doing, and of course there are the general risks of that.

I don't want to destroy my battery... It drops too much like this, with overvolting it will die in five minutes
when i use 729 or above my Cpu stops working and its Reboot automaticaly any way to fix
Unfortunately you can't fix it. The overclock ability of the cpu is different in each phone. Some x8 can run on 800+ MHz, some can't reach frequencies over 700MHz. Basically the SoC (the cpu, gpu, dsp and some other device) contains millions of transistors, but the whole chip is only ONE small piece of silicium, the transistors made by litographic and other complex (and expensive) procedures. The overclock ability depends on the material quality (damages in the silicium structure), soldering quality between the core and the casing, etc. So, no existing rules to the overclock, if you lucky you can reach high frequencies, if you unlucky you can't overclock.
Note: under the manufacturing procedure the chips get a selection after testing, the highest quality 7x27 chips marked and sold as 7x27T with default 800MHz.
There is an app in the market called No Frills CPU Control: https://play.google.com/store/apps/details?id=it.sineo.android.noFrillsCPU
It will automatically change your CPU frequencies during boot to save your phone from hard bricking.
Anyway CPU gets overheated by overclocking as more amount of power comes in to it than what is required. So as a long term effect your CPU will die out and also your Battery too. So I would say to use a faster rom and dont overclock the CPU to very high frequencies.

You are using stock kernel?
Overclocking more than 729 is not possible for stock kernel...
Use "set CPU" application & remember to uncheck "set on boot "option

governer also matters, I always use smartassv2
As someone wise already stated, better using something like FroyoPro which is blazing fast compared to any GB rom instead of overclocking.
I can do more with FroyoPro than anyone running GB, ICS or JB roms.
It's just simple - lighter code takes less cpu cycles therefore it is quicker.
GB, ICS and JB roms really are a waste of time once you've tried FroyoPro.
The other roms are really only good for proof of concept - not for everyday usage.

I tried it , it's not that much good:/ plus it have so many bugs with alfs kernel.(brightness bug for example)
I compared it with iXperia 8s rom before, froyopro is better @ one of 3d tests(just 2 fps better)
Other test were like iXpera & minicm7
Remember it's froyo & they are ginger ,they can run newer apps .
My opinion iXperia is our best rom till now

It also depends on the kernel you are using..Alfs is better in this aspect..but too much overclocking is not recommended.
if you are using custom kernel ,under CPU settings, select the frequencies you desire and do NOT select "Set on boot" . Even if your phone gets rebooted due to overclocking the default values will be applied at boot. This way you can avoid problems.

please read 2nd post by pilu. that's the best explanation. it's a hardware limitation, and it does NOT depend on the kernel.
[cAs]
Partially depends from the kernel too. The cpu clock is not only a simple value: xyz mhz. In the kernel this is a little bit complicated (pll frequencies, dividers, multipliers, voltage level, etc). Different kernels use different frequency tables, the results can be different, this the developer choice who can set different bus speeds (axi, ahb), base pll, voltage to every clock speed. You only see the frequencies in the different kernels, what is same, but the same speed maybe generated with different method.
So, the cpu overclock ability is 90% hardware limitation and 10% other things. Usually if you reach your own max speed with a kernel, the probability of higher speed with another kernel is small, the typical difference is nothing more than +/- 1 multiplier (+/- 19,2 mhz).
