hello, i am trying to make a kernel for samsung galaxy player 5.0 which has same cpu&gpu as well known gt-i9000.
I have successfully overclocked cpu from 1.2ghz to 1.6ghz but benchmark results on added frequencies are worse than at stock. But if I use tegrak overclock and set same freq and voltage as in my overcloked kernel, then everything is okay and benchmark results are much better.
any idea or you need more information?
about gpu, I changed it frequency in drivers/gpu/pvr/s5p110c/sysconfig.c but it doesn't give any benefits. what also should I edit/change to successfully overclock gpu?

Gpu overclocking is not working this way. Our gpu speed is linked to the main bus speed. To overclock the gpu, you need to overclock the bus (this is known as liveoc for the i9000).
Why CPU oc is not working, idk. Have you defined proper apll values for the added freq?

On Infuse, I found that somehow adding extra frequency steps could cause the device to get jammed at whatever the policy minimum was set.
I haven't had time to figure out why.
wow, big thanks guys :> gonna try without extra frequncies and try to overclock bus too (I have read that liveoc isn't as steble and generally is worse than normal oc)

I just saw the specs of galaxy ace.
Same adreno 200 gpu as our's and the same processor msm7227 but clocked at 800 Mhz....wtf?
I couldnt overclock my phone to a stable 806 ever
Can anyone make any comments please??

Kernel matters rolleys.
Sent from my LG-P500 using XDA Premium App
Yes, Its due to kernel only. And not to worry so mush. What FK has given us till now you can use @ 768, It's not bad at all.
lol binodray, u know about android or ur just acting like u know??
we cant overclock because the msm7227 in our device is connected to cheap cables and busses and probably cheap ahb or something...
thats y some people are able to overclock to 806 and some people are not able to...
No dear I don’t know anything.
On a short note
The MSM7227 is ARM 11 family 32bit Qualcomm MSM7225 processor. This series seems to run PLL2 at 1200MHz, which is why they are capable of running at 600MHz. (1200/2 binary thing).
what is over clocking?
Over clocking typically refers to running a CPU at a clock speed higher than that for which it was originally designed. And the kernel is told that it is being run at a higher speed (In realty it’s not).
Why phone crash?
When phone generate very high voltage due to increased clock speed we have kernel panic in result.
How we solve this?
As far as I know if dev can alter UV table in kernel we can have processor with 1728 which is 864. This means there could be one kernel supporting OC frequencies up to 1728Mhz (lets say 1728,1600,1500,1400,1300,1200,1120), and user could choose which ones he wants to use (eg 1400 and 1120, disabling the rest).
Hope this will make you clear why we need kernel and why OC is based on kernel codes.
is there any option to raise SGS3 CPU to 2000mhz or something like that?
EDIT: NEW AS 14/7
kk so i guess the highest and most stablest cpu might be till 1800mhz
1and what about ram? there is any overclocking for ram memory? (couldnt find anything about it)
2what about GPU?
not yet, i think the highest clock right now is 1.5 for the sgs3
and RAM, NO you can not get MORE ram, you can eliminate apps that eating up ram to free some up but no way to get more ram.
is there any need to overclock this beast lol its fast enough

He wasn't referring to getting more RAM though was he? It read to me that he wanted to see if was possible to increase the clock speed of the RAM along with the CPU.
yep just wondering if there is any option for that as in SGS1+2
do you guys think when there is OC for s3, it will raise CPU to 2000MHz ?

Already there OC/UV running 1500Mhz right now. Max 1800Mhz.
Look into de developers topics for the kernel..
Ive looked there.. stiil misunderstand something-
there is any OC of 2000mhz now?
Note that the Exynos 4Core CPU is still not very well understood and may well get long-time damage when ramping up the clock speed aggressively.
Is there actually ANY need for going so high except to show off?
You'll be measuring any speed improvement in loading things up in microseconds because people say Samsung still hasn't fully optimised the phone to the OS yet, so I think it's a bit pointless stressing the phone that much.
1.8GHZ is currently the max however with kmemhelper you should be able to change the last frequency to 2.0...
Hell I'll even find out the script for you if you are mad enough to try it first

I doubt you'll get it 2GHz stable anyway. From what I've heard most people have theirs crap out at 1.8GHz.

1and what about ram? there is any overclocking for ram memory? (couldnt find anything about it)

to make it clear:
i wanna know which ram overclocking is available to do on the SGS3 as long as the device still stables.
same with GPU and all those stuff.. there is a really good lvl of OC like in S1 S2?
still waiting for help
I would go for Siyah kernel and try 1.8 GHz then under volt using voltage control or extweaks app. Most phones can go 100 mv on all steps except maybe the very highest clocks.
gpu overclock is not possible yet
Sent from my GT-I9300 using xda premium
OC of the ram is connected to bus speed and this is very different to the fixed bus in the sgs1 so nothing like live oc is possible. Still 400 mhz bus speed is 4 times faster than the CHAt!
Sent from my GT-I9300 using xda premium
I`am running RGUI v7 rom and siyah kernel 1.3.8a. My clockspeed is 1600 Mhz and is rockstable, snappy and battery life is great.
I don`t go any higher for daily use, it doesn`t make much difference in speed and i think it cuts down your cpu-life.
ho so no LIVE OC is available now? (like in S1 and s2)?
well hoping it will be possible to add those functions(live oc, ram, cpu, and more..) in Android JB 4.1
My Captivate (SGS1) can hit 1.92GHz... So I think that a CPU with a stock clock of 1.4GHz can hit 2GHz easily. We will just have to see. I am not pushing this phone though. I don't have $700 to replace it.

That's not depended on the ROM but on whether the hardware allows to modify the values and if kernel developers figure out how to do it.
just wondering, there's so much talk about overclocking CPU.
why no discussion on overclocking for GPU? is it possible?
i think if the higher GPU clockspeed improve performance even more than CPU clock speed, doesn't it?
if i understand correctly, galaxy nexus GPU is the same as galaxy S1. but with much higher clock speed. So the GPU speed can be made higher right?
Some kernel, as Siyah allows you (with extweaks) to overclock gpu up to 400 mhz, but I think this is useless, no app need more than 200-267 mhz.
A good idea can be downclock gpu and cpu frequency and decrease voltages to save battery.

Gpu steps are 3. According to information provided by extweaks default frequency values are 160, 267, 267, but you can set as you want.

That is the "Performace" setting of siyah(160, 267, 267). Or maybe it is the default but siyah considers it as a performance setting

Hi! I have problem with perseus Kernel If I overclock cpu a little bit, All the same the problem (If I start play game some time it will restart), it does not matter how much overclocked. I tested 1.7Ghz clock and test it For 1375mv, 1400mv, 1425mv, and it's not effective and between a perseus rom freezes lock screen and I have to restart it :S, siyah kernel will not let me even overclock more than 1.5GHz can someone help me with this problem :laugh:, I love overclocking :silly:

Okay But, why I'm not able to overclock 1.8GhZ its show me 200-1.5GhZ I tried overclock stweaks, cpu master, set cpu, and Foxhound extras but not help I try flash siyah again If that help.. Block story max settings eat really MUCH performance
I'm not even able hit over the 1.5GhZ and it show me 25-1.5GhZ (((
Anyone?
Anyone know what I do wrong if I'm not able hit 1.8GhZ?
yes,, your cpu isn't up to it, simple. With overclocking make small steps, note what you are doing, experiment with voltages, but all chips are different so experimentation is the only way, along with lots of reading and learning, skill aided by searching

you have to understand the fact that the kernel is in alpha stage, so if you dont know what you are doing you shouldnt have flashed it. and also all chips are not capable of handling higher frequency, 1.6 ghz should be asafe bet for all processors..
700mhz in siyah makes a big impact depending on the benchmark you run.. check the thrread in my sig for more info.
Thanks all for posts! I figured it out, I give more juice for all these steps for perseus alpha And not anymore reboots. 1.8 GhZ 1450mv 1.7GhZ 1400mv, 1.6GhZ 1350mV, 1.5GhZ 1300mV, I run now 1.7GhZ for dual core mode, I'll try soon run my phone quad core mode . But I can't overclock my gpu with perseus and siyah rom doesn't give me overclock more than 1.5ghZ DD so strange Ps: 1.7 GhZ Dual core My Cpu score is 8123 and memory 5538 on quandrant benchmark.
Edit: If my phone a little bit overheat it reboot same thing is 1.6GhZ, 1.7GhZ, 1.8GhZ. 1.6GhZ I run stability test about 1-2min and it reboot, Battery About 41 degrees Celsius :S
Why in the name of all that is holy would you overclock your CPU, and then run it in dual core mode??
You would be better off leaving it at 1.4ghz in quad core mode.
That seems pointless.

hey there .i wanted to know if custom kernels have effect on processor speed so that they could damage the processor on long term ,or not ?
you can overclock CPU on custom kernel, and then you can burn it. but I think it won't overclock by itself,

i wont do that but i'm afraid that the custom rom or kernel will make this it self ,what makes me confused that i flashed a kernel today and noticed better performance and more rapid than previous so i'm afraid that this deference is because boosting processor speed in these custom kernels or roms
this kernel is "MESA" on "Hyberbeam Rom" in the kernel description there is a sentence that got me panicked which is "oc upto 1.8ghz and using 200mhz steps. default boot only use 1ghz."
so i want to know what this means
it means that you can oc up to 1.8 GHz if you really want. just use No-frills CPU Control or SetCPU to manage your CPU, you can check the current clock speed and set the min and max frequency limit, so if you set the max to 1 GHz you can be sure that you won't fry the CPU... unless you'll set the governor to performance.
the kernel or custom rom don't oc the cpu by themselves...... btw you can oc your cpu to 1.2 gigs safely..... i am using my phone on that frequency from last two months
and the speed increase you are talking about is because of the various tweaks and scripts that are used in the custom rom and kernel and the removed bloatware
