Issue

When i make overclock to 1350 the mob. freeze and reboot :mad: please fix
[Galaxy S II I9100G Android Development] :
I cant fix this this is a problem of your mobile phone
[Galaxy S II I9100G Android Development] lifenexus:
here is a little thing about electronics. You cannot manufacture them exactly the same each time. every semiconductor manufactured will have slightly properties, thermal dissipation, electrical conductivity, resistance, etc.. so these small differences can make them stable at different voltages and frequencies of oscillations. If your cpu is unable to run at a particular clock speed and voltage, there is nothing you can do about it. Its a manufacturing thing. When a cpu is manufactured, its made sure that it runs stable at a reference frequency. They cant make sure that is fits every users desire.

Its just how it is. There is nothing you can do about it and you cant blame the manufacturer. If you see how incredibly close the transistors are on your cpu, you will be shocked as of how they do it in the first place. You can read about it if you like. Ill just give you a few hints to search. Electron bean lithography and photolithography. Happy searching :)
[Galaxy S II I9100G Android Development] vincenz:
Ya, i agree. Im having same issue too but i just posted it without asking to fix. Caused no one else having this earlier, so i assumed its my hardware instead fuss's kernel issue.

Environments factor is very important for an electronics device.

Do u think it related to this problem? :confused:

Correct me if im wrong..
[Galaxy S II I9100G Android Development] :
i have rev 3 (v 71)

never had any problem like reboot. can run at 150 MHz or 1350 MHz without problem. purchased last feb 2012. think now is good time to verify this rev version 'issue'

perhaps fuss132 can put up a poll maybe :)
[Galaxy S II I9100G Android Development] lessirey:
Mine is rev 3 too.. and didn't experience any such issue at all.
[Galaxy S II I9100G Android Development] iXanza:
mines rev3 too. i guess people with rev2 are facing this
[Galaxy S II I9100G Android Development] tribalfusionaxe:
Ya, i think only rev2 have this problem..i bought mine end of sept 2011..so, who bought early get rev2 and have this problem.. :(

Time to change phone i think.. :p
[Galaxy S II I9100G Android Development] sathiere:
Rev 3 (v7l) for me as well. Purchased in May 2012.

1350MHz works, but I don't really see the point in OC, as the power consumption increases significantly for the additional 150MHz. Personally, I don't need the additional speed if the drawback is less battery life.

So, here come my personal UV settings, where I got the device to be stable (set min/max limit to one frequency / under-volt /run stability test / if it crashes, adjust UV):

1200MHz: 1175mV

1008MHz: 1075mV

800MHz: 975mV

600MHz: 875mV

300MHz: 750mV (min limit)

150MHz: 750mV (min limit)

At 1350MHz I got some strange results, because it was stable in the Test @ 1275mV, but crashed in real-world. But I would attribute that more to the combination of OC+UV+hotplug governor - so I reverted to 1200MHz and am happy.

750mV at 150MHz and 300MHz result from the fact that you cannot UV to less than 750mV for any given frequency (well, you can type in a lower number in setCPU, but it won't have any effect).

Subsequently, at least for my device, under-clocking to 150MHz does not yield any improvement over 300MHz, as the voltage level can be set to match...I would assume that @ 150MHz voltage level could be as low as 650~675mV...
[Galaxy S II I9100G Android Development] lessirey:
Thx for sharing :)
[Galaxy S II I9100G Android Development] jetse7en:
Work in stability test but not for daily use, sometime system crashed and reboot.

I tested
[Galaxy S II I9100G Android Development] sathiere:
In the end, stability test can only be only one part of the assessment. Nothing beats real life testing. And then there are also the excursions in the different hardware builds.

But, as a first assessment, stability test is a good tool...
[Galaxy S II I9100G Android Development] kirankm:
How do you know that 750mV is the minimu value for any frequency? :confused:
[Galaxy S II I9100G Android Development] sathiere:
It is the lowest you can set in voltage control - and whatever lower number you set in setCPU, the device never freezes, means, it has no effect.

Therefore, I thinkit is an accurate guess that min voltage is 750mV...
[Galaxy S II I9100G Android Development] kirankm:
oh thanks for the quick reply.

The thing is in S3 forum I remember seeing someone posting 675 as their value for 100 mhz. He must have just entered the value using setcpu then.

I just went to the voltage control play store page and it looks like the app has a under volting limit of -250. So 750 may not be the limit on minimum undervolt possible. It could be just the restriction by the app.

I am using lite version and hence i can only go down to 800 (-200 undervolt).

Since setcpu has a silder which can go down to 600 MHz i think it is possible to undervolt upto that limit.
[Galaxy S II I9100G Android Development] sathiere:
I think the min threshold in voltage control is based on the initial voltage setting.

Voltage Control can UV dwon to 250mV less than initial value. Initial value for 300MHz was (probably, unconfirmed) 1000mV, hence, the 750mV minimum.

When fuss set-up the additional 150MHz frequency step, he maybe copied the voltage setting from the 300MHz step - just an assumption from my side...
[Galaxy S II I9100G Android Development] codybank_789:
Maybe setcpu IS working. Freeze does happen and after setting 150mhz at 650 in setcpu, voltage control show the same too.
[Galaxy S II I9100G Android Development] karimrim:
I'd love to apply your settings, just bought Voltage Control Extreme,

but I don't have Voltage tab! Please help :D

Using horsepower 1.3.5
[Galaxy S II I9100G Android Development] kirankm:
1.3.5 doesn't have undervolting. You need the testkernel version. Also the test version is only for jelly bean. Don't flash it for ICS
[Galaxy S II I9100G Android Development] karimrim:
Thanks for the info!

Will undervolting be available for ICS eventually ?

Edit : my bad, ICS version is not ready yet, found fuss post =)
[Galaxy S II I9100G Android Development] :
Both kernel versions are compiling atm so it will take propably one more hour until the new versions are ready
[Galaxy S II I9100G Android Development] kirankm:
Could you make the kernel work at 300 MHz in the recovery mode.

[Galaxy S II I9100G Android Development] chincheeken:
anyone that is running fuss's hp 2.0 on cm10, can do me a favour and check if you guys can get the max value to anything Other than 1200?

in my case eventhough i change to 600/800/1008, it will jump back to 1200 afterwards? :(
[Galaxy S II I9100G Android Development] jifat:
Yup.. Pls fuss really need it. To avoid hang in recovery. Currently can use aidfarh kernel only at min 300 MHz.
[Galaxy S II I9100G Android Development] Senjax:

Thanks a lot fuss. Finally your kernel is working perfectly in my mobile. The phone is working properly in recovery mode now.
[Galaxy S II I9100G Android Development] incarnation95:
* rebased ics means that it ll work for the ics roms too.... as these features were added only to the jb kernel.

* no touch recovery because people prefer that .... maybe :p and some had a buggy one:confused:

* chainfire? The hell did that come from..... go ask chainfire as it is his thung not fuss's
[Galaxy S II I9100G Android Development] midograna:

For ICS version everything is fine. I reduced the max. frequency to 800 MHz and it's working.

[Galaxy S II I9100G Android Development] creezalird:
it seems most users with rev2 cpu are having problem with this kernel. with the previous version touch recovery, they could not even boot up the device.

i am not sure what is wrong as mine is rev3, so lucky me
[Galaxy S II I9100G Android Development] kirankm:
The kernel is supported. It is just that they are not able to underclock or overclock. However the other features of the kernel, like deep idle and core management , should still be working.

Devices having rev 2 and rev 3 both are showing the problem. So I don't think it is an issue with the processor.

Also some of us had an issue with phone freezing at recovery menu. This was because, for some of us, the phone could not run the recovery mode at 150 mhz.

In the new version the default speed is 300 Mhz. Hence the screen is no longer getting frozen at recovery.
[Galaxy S II I9100G Android Development] iXanza:
When's AutoPerform gonna be implemented?
[Galaxy S II I9100G Android Development] 301stSpartan:
Hey Fuss, I know this has been reported before by other users, but what I'm experiencing seems to be a bit different. After setting the governor and frequency settings, my phone keeps going back to 150-1350 on hotplug. For example, if I set it to 150-600 interactive, a few minutes later it's running 150-1350 hotplug. Does this regardless of the method I use to set the options (performance settings, setcpu, voltage control). Also, it seems to reset basically as soon as I turn the screen off and back on again.

Others reported this, but they reported it going back up to 1200, not 1350. Also, I don't think anyone else reported the governor changing either. Maybe they didn't notice or maybe my phone is just strange. :silly:

Edit: sorry, I have a r3 chip, running CM10 and kernel 2.0.6
[Galaxy S II I9100G Android Development] creezalird:
mine is rev3 and i am not having any of the issues...even not freezing at recovery since every release of horsepower...how would u comment for that? ;)
[Galaxy S II I9100G Android Development] kirankm:
As lifenexus posted earlier, no 2 devices will exactly be the same. There will always be small differences. While testing, manufacturer just ensures that the device works without issues under stock settings. i.e default stock governor, stock max and min cpu etc.

By overclocking and/or underclocking we are making the device perform in conditions in which it has not been tested. So for some lucky users (like you) the device is able to perform without problems under the new conditions. But for some of us the device causes some errors. Also as you can see different users have experienced different errors. Some have problem with underclocking, some with overclocking etc. I believe this is also why different devices have different undervolting abilities.

I am not an expert on this topic and i could be wrong but this is my understanding of the situation. :)
[Galaxy S II I9100G Android Development] 301stSpartan:
After flashing the 0731 CM10, then gapps, then the 2.0.6 kernel, my phone kept reverting back to 150-600 interactive for some odd reason. Kept resetting back to this every time the screen turned off too.

Now after a reboot, it's resetting to 150-1200 hot plug when the screen is turned off.

Sent from my 9100G, running the amazing CM10
[Galaxy S II I9100G Android Development] creezalird:
i am not an expert too :P

but a small conclusion that rev2 users are having more problems than rev3..so far from our own group discussions, only rev2 users are reporting problems, and rev3 users are all happy :P

but anyway, we will just wait for the dev...
[Galaxy S II I9100G Android Development] kirankm:
Actually i am using r3 and my phone used to freeze in recovery mode when default speed was 150 mhz. Also some other users (chincheeken, 301stspartan, jetse7en) who have r3 are also having issues. Which is why i said that it might not be an issue with the processor being r2 or r3.

Fastcharge allows you to force the phone to treat a computer's USB port like an AC charger. It disables the data connection and tries to pull more than 500 mA from the USB port. Some say there's a risk of damaging your equipment when you do this, but I don't know how true it is. In my kernel, it's disabled by default. There's a few ways to toggle it. Read this post for more info (the particular post is for another phone, but the implementation's basically the same):
