Rafael.Baugis, try to extend the range of frequencies in the standard governor BM21553, maybe it will give us some pros
[Galaxy Ace S5830i Android Development] maciej_s20:
my tests on v0906, userspace, noop, min=max, as requested by Rafael.

Look at my next post with result's analysis.
[Galaxy Ace S5830i Android Development] maciej_s20:
I've done some further tests and compared them to those published by Rafael (I assume Rafael's were done with 0909 kernel).

For clarity I've removed 208MHz which works as advertised.

Here comes the numbers:

20120906-1926-CWM-(936Mhz)	(my tests)
freq	ram	cpu_int	cpu_fl	2d	3d	db io	total
312	73	143	105	239	376	120	1056
624	111	217	158	240	402	175	1303

936	149	292	213	241	403	220	1518

Rafael's own test on v0909

1. GPU (2d and 3d) performance in AnTuTu.

http://xdaforums.com/attachment.php?attachmentid=1316371&d=1347297057

Conclusion:

- There is almost no improvement in different kernels.
- GPU performance scales very,very little with kernel and frequency changes.

2. CPU (int and float) and memory score in AnTuTu

http://xdaforums.com/attachment.php?attachmentid=1316350&d=1347296169

Conclusion:

1. There are ONLY four frequency steps, regardless what CPU app says:
- 1st. step: v.0909@208MHz
- 2nd. step: 312MHz in both kernels, v.0909@624MHz (all are the same)
- 3rd. step: 832MHz in both kernels, v.0906@624MHz, v.0909@936MHz (all are the same)
- 4th. step: v.0906@936MHz, v.0909@1248MHz (in fact 1248 is even slower than 936)

2. Memory speed is also limited to four steps, same proportion applies
as for CPU calculations.

3. Different kernels offers the same frequencies with only names changed.

3. Total score.

Yes, "total score" is different - but I would assume that AnTuTu accounts for declared frequency, not real CPU speed. CPU/GPU/Mem tests in AnTuTu as well as Linpack shows no improvements in performance.

If we look at "db io" parameter, it looks different between kernels, but still 1248MHz in 0909 is equal to 936 in 0906. Maybe kernels did some minor tweaks to io parameters. But those are only minors, You may check yourself.

Real tests shows that something is seriously broken with frequencies in Rafael's kernel. If we take into an account that stock Samsung kernel at 832MHz gives the same result in Linpack as 1.24Ghz in Rafael's OC kernel than we can easy think that even if we set 1.24G we get only 832M. Look - 50% improvement in frequency gives 0% improvement in result.

We have a different, new freq. names with old frequencies inside. No new frequencies and no advantage in speed.

Correct me, if I'm wrong - but first look at pictures attached.
[Galaxy Ace S5830i Android Development] AndroGeeker:
Bro, please remove your kernel logo and leave it with Samsung default. I know it's your hard work to bring the custom kernel for us but having Samsung's default kernel logo will be great.

[Galaxy Ace S5830i Android Development] ZakooZ:
A kernel can't "burn your motherboard"

Unless you actually overclocked to 1200mhz for hours without knowing the risks. Even then it's doubtful because I would imagine theres a automatic shutdown when temperatures get dangerous.

Probably a soft brick
[Galaxy Ace S5830i Android Development] paradoxiumwind:
the CPU will most definitely turn off long before it overheats enough to damage it at all
[Galaxy Ace S5830i Android Development] saeed14i:
You phone might have bricked. Search tutorials about unbricking your phone. Also are you sure that your phone model is 5830i and not 5830 ? both models can't have each others' Firmware or Kernel etc

Thanks the solved my problem now i am using 1248ghz.

Rafael u told me in another comment that 998mhz was very dangeorus now i haved 1248ghz is not these worse??

Sorry my engish

1248ghz is working very good :)
[Galaxy Ace S5830i Android Development] Rafael.Baugis:
After his analysis, I am testing.

and I think you're right!

I am doing the same way to overclock galaxy Y, I think it will take time to have overclock bcm21553.

does not help, change the multiplier or divider, I think it is fixed by the register.

Ex:

0x0A

0x0B

0x0C

0x0E

0x0F is the last, wont anymore!

see last kernel!

Very thanks to all, and sorry to all.
[Galaxy Ace S5830i Android Development] Bert98:
Sorry but i didn't understand very well.. Do you mean that 832Mhz is the maximum for the BCM21553 governor or is it the maximum for our phone?

[Galaxy Ace S5830i Android Development] jasliau:
What about other governor?

Will the OC work? I'm curious because the latest version got all higher than 832mhz removed.
[Galaxy Ace S5830i Android Development] dark.14:
thank you so much for you working kernels :)

---------- Post added at 03:51 PM ---------- Previous post was at 03:32 PM ----------

i just flashed your latest kernel and the overclock was gone.. :( why?
[Galaxy Ace S5830i Android Development] maciej_s20:
No. It means it is currently the maximum of this CPU (unless someone will find a way to program it for larger frequencies).

Older kernels had a bug. They declared that are able to reach higher freq., but they did not.

It also means, that if You will set 1.24GHz on older kernels in reallity You get 832MHz. No even a single kernel allowed for higher real freq. than 832Mhz. Period. It does not matter which governor will be used. Look at graphs in my previous post - it shows the problem clearly.

All those kernels regardles gave us only a 4 frequency steps:

As You can see v.0906@936MHz and v.0909@1248MHz are offering the same speed, which is equivalent to stock kernel at 832MHz.

Sorry - no OC in S5830i at this time. Only plain old stock 832MHz. There is no need to use older kernels which allowed to choose higher, OC freqs. They were no faster than default 832MHz. In each of them the highest freq. available, regardless how it was named, provided You with cpu at 832MHz only.

Example: kernel v0906 at 936MHz has beeen running at 832M, kernel v0909 at 1.24GHz has been also running on 832M only.

They gave You no improvement in performance. The only score that has been changing was AnTuTu total score, but no even single sub-result (cpu, float, mem and others) showed any improvement. The same applies for other benchmarks tried on those "OC" kernels. So - AnTuTu "total" score is not a real measurement because it is calculated not only using bechmarks, but also using data from kernel (what the kernel thinks it is running on).

You may remove this proud "1.24GHz smoothass" from sigs as there is no such a frequency available, and had never been.

Apart from not allowing for OC, Rafael's kernel works flawlessly and smooth. Thanks for Your work, Rafael!
[Galaxy Ace S5830i Android Development] P@t@r:
Conclusion

So, generally this means when we flash the latest kernel we also can remove this CPU frills program?

May I assume the latest kernel available right now is the best?

What happens with init.d scripts i use right now? Do i have to do something before flashing this kernel or is it just flash and all will be good?
[Galaxy Ace S5830i Android Development] ZakooZ:
Is it possible to override the 832mhz limit or the CPU just sucks just like the GPU?

Definitely starting to regret buying this phone...
[Galaxy Ace S5830i Android Development] maciej_s20:
We don't know yet if it's possible, but for this very moment it is not.
[Galaxy Ace S5830i Android Development] domnic79:
Same here. No OC, No cyanogenmod & No GPU source. It sucks. I used 5830 fr a year. Sold it. Got dis fone thinking it ws 5830, bt it wasnt as cool as 5830. Maybe it wil take time for d development work on this fone to come alive.
[Galaxy Ace S5830i Android Development] P@t@r:
Another question:

To get add governal file, can I just flash this the same way I do with kernel? Will they be added automaticly?

Sorry, just want to be sure before i screw up something.
[Galaxy Ace S5830i Android Development] vivanco:

According to no frills app included, deepsleep doesn't work... Anyone know why? Becouse older kernels was be able to enter deepsleep mode. Something I have downloaded? link2sd perhaps?
[Galaxy Ace S5830i Android Development] saeed14i:
Reportedly, No-Frills CPU app does not accurately report statistics. Use "Cpu Spy" from google play store for more accurate results. Deep sleep is working fine for me on the latest rev-20120910-2252. I got issues with deep sleep when i installed Link2Sd on a custom ROM Called "AceCream". Apart from that, even with Link2Sd, deep sleep is working perfectly with Rafael's Kernel. I also checked it on Stock rom with Rafael's Kernel and deep sleep is working fine even with Link2Sd. If you still have doubts or your phone does not go into deep sleep, use "betterbatterystats" app for more advanced features and reports. It will tell you exactly which process is preventing your phone to go into deep sleep. Hope this helps

The script should be on the SD card. You'll have to run it again tho (since system files are restored), but you won't have to do all changes again -the script will automagically restore your settings (unless you refuse), and all you'll have to do is restart your device.

Your phone being faster can be because of other elements (e.g. installing a new ROM, using memory management scripts, chainfire 3D, etc).
[Galaxy Ace S5830i Android Development] Abel669:
I'm still adament im a lucky one though. I'll give you a little idea of what i have done:

Flashed LH2 firmware (stock, non-deoxed), flashed stable CWM, Flashed latest Kernel, Overclocked. I dont personally care what the "evidence" says, i genuinely believe that the phone is faster. I appreciate the fact your trying to prove its all in my head, but the Android OS says different lol. For example F-Sim space flight simulator, worked (ish) standard..when i overclocked it, it worked like a dream.
[Galaxy Ace S5830i Android Development] GermainZ:
It could be because you're forcing your phone on running at 832Mhz constant. Using the normal frequencies with the performance governor should do the same.
[Galaxy Ace S5830i Android Development] Abel669:
Could very well be. I'll do some testing to see what actually happens. It is a shame that OC is not possible yet though. Another thing to add to the list of crap this phone screwed us on
[Galaxy Ace S5830i Android Development] ZakooZ:
Antutu did display slightly better performance with overlocked CPU though... So that's pretty weird
[Galaxy Ace S5830i Android Development] maciej_s20:
In fact it did not. Only the AnTuTu "total" score was higher, but no other single sub-result. Probably AnTuTu reads the frequency the kernel declares to run on and adds it somehow to total score. But this is not a real improvement.

Other tests (like linpack) shows the same - no improvement. So - if we'll take all of this there was no improvement in phone speed.

Look at the picture attached - it shows CPU performance in two different kernels with different frequencies.

http://xdaforums.com/attachment.php?attachmentid=1318793&d=1347375662
[Galaxy Ace S5830i Android Development] maciej_s20:
It can be Your feeling, but at best this is due to frequency steps the kernel intruduced or new firmware installed or phone cleaned.

CPU has never been faster than 832M. Look below - this will be example for kernel v.0909:

So - if governor tried to change speed - it stayed at the same level for both 936 and 832Mhz, which could look like faster phone. Obviously other optimizations in kernel could give it better performance than stock one - for sure. But exactly the same performance is offered by last kernel (i.e. this without OC) when CPU runs at 832M.
[Galaxy Ace S5830i Android Development] schakusa:
Good news, more stable so :D

Who really need overclock a mobile phone? to run apps faster? cmon... to improve fps in games? ~100-200mhz doesn't worth for the risk, honestly.

I have my desktop PC overclocked +400 MHz but I have a custom cooler too, and really is not a big difference fps improvement for games... seriously what can do < 200mhz on a mobile phone? and this without mention a long gampleay can burn literally your NO-COOLING MOBILE PHONE.

I think a proper sources, good programming or the idyllic broadcom videocore iv sources (capable to 1080p encoding) is what we really need instead oc. Thats my opinion.
