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??
take a look

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.
Anyone can overclock this RK2918 chipset? The performance of this tablet isn't that fast with the stock firmware, I hope someone can overclock the CPU and GPU.
a kernel that allows overclock is allowed, but at the moment noone is working on (for what I know). Try the Evolution 1.12 is much faster than other roms. How much do you have on the Antutu benchmark?
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:
SiyahKernel S3 v1.5 CPU over/underclock: 100-1800MHz 18-steps , GPU over/underclock: 54-800MHz ,Perfect to play , i have been using for a long time and i had never any problems ........

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

okay But why this perseus give me overclock more than 1.5GhZ But Perseus is so buggy :S and I can normally overclock Gpu with siyah kernel but If I run test I am not note difference, 1 better fps for 700MhZ GPU Clock My Phone is so strange

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.

I make video today

http://www.youtube.com/watch?v=glPp2ORTvFo&feature=youtu.be Sorry for poor video my video editing software doesn't working But If I run test about 1 min device reboot My video will not be saved if it shuts down so I had to stop Stability Test before a turn off.
I will do later in the evening siyah kernel video for overclocking problem
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)

how to overclock galaxy y ? i have flashed kernel with merruk v.2.0 and use jellyblast v.3.0.3 ROM , but cpu frequency in my galaxy y still 832 MHz, please help. thanks

Hi all,
I have a problem with my 5770d tab.
The cpu only makes 1,2 ghz max. But it must have 1,5 ghz.
I had rooted it but any cpu app dos'nt work.
also it shows me the cpu is a arm v7 but it must be a cortex a8 i think.
can someone tell me what is wrong!?
Thx for your help and sry about my english.

Looking at the specs of the device it says up to 1.5 GHz max the manufacturer likely limited the max frequency to battery life and performance. To get the CPU frequency to 1.5 GHz and higher you would need a custom kernel that allows for the higher CPU clock speeds. Also the processor that is used is based on the cortex a9 architecture and uses the arm v7 instruction set (Hence where the arm v7 comes from). Let me know if you still have questions .

Hey, thank you very much! :good:
Then i know that everything is ok.
It´s too bad that there are no Custom Kernels and Roms up today.
Hope this will change in the future.
