Hey guys,
Can anyone give me a bit of advice on where i can find some information about where to read about making my own script for my Kernel , to control the Cpu scaling? I have been trying to look everywhere but i cant see anything
Just want to customise the Kernel a bit more and see if i can mess around with the scaling,
Thanks guys,
Or if anyone knows a decent script were the CPU stays mostly at 500mhz underload unless it really needs to jump up to 800...
Im keep my GS2 Underclocked to 800mhz (In hope of better battery life)..
And noticed the time it stays in 800mhz and 500mhz are quite even, I would like to to hover on 500mhz more often..
Thanks ^_^

Why my phone does not support OC ?
Non OC kernels and roms work just fine but with OC always bootloop.
Is this hardware based or software based restriction? Anyway to bypass this?
Thanks for help
There is a maximum your phone can overclock to before it begins drawing too much power for it to handle. Maybe you are trying to push it too far?

Or maybe you should try using a kernel that can actually be overclocked...

Well, I take it for granted that you have the right kernel with OC support.
Once you have the right kernel -generally speaking- and one application that manages the OC (or the terminal itself) you've gone half way long, since not any Cpu is the same, even if it should be, according to the manifacturer.
The naked truth is that Cpus are built in order to match the standard clock to which they are set, while some of them can bear a huge overclock. But the matter is that you have got to play with undervolt and overvolt, to get the right tuning.
Most patched kernel support a uv-ov fine tuning and each of us must look for the right tuning for his own device.
Always generally speaking, you can look for "smartreflex technology" to get what it is (it something by Texas Instruments).
So for example, my gio stock clock speed is 787 (actaully runs at 800 though on stock roms). Some people can overclock it 940MHz stable, while some people (like me) can only stably overclock to a mere 844. One tick over to 864 for me, and the whole thing craters and reboots like crazy.
Im using Cyanogen Mod 9 and the kernel does not support Over/Under Volting, only CPU scaling. So if i got a new kernel that supported everything my one does now like init.d, scaling, and all of that good stuff, if i was to overvolt, would my CPU handle a larger overclock? Or is this simply limited by the variations between cpu's when it was built?
Well, I am neither a professional coder nor a CPU manifacturer but, according to my one year experience at Nokia n900 Italia forum, which I think could be referred to any arm cpu, even if the phone runs android, the differences between the same CPU are huge band the only way to get the best id to try a lot.
For example, my n900 CPU standard running at 600 MHz, could not bear extremely undervolted profiles but, at standard voltage, was stable at 1150 MHz...
So, just try though imho undervolting and scaling to save battery life are more appealing than oc itself.

One more thing, because I had missed a part of your post.
IMHO overclocking and overvolting together are the evil itself because of the heat that such thing would cause and the phone is not a pc with its fan to refresh...
Much better oc and undervolting
Can i overclock my OPTIMUS ONE p500 running with 4WiSEMONKEYS ROM to
Minimum CPU frequency = 320 or 480
Maximum CPU frequency = 729..
CAN I OVERCLOCK IT?
what is the disadvantage of this? or what is the bad result of this??
PLEASE HELP GUYS!
thanks
Read other threads first..................
I think 320 and 691 is best for our O1

Yes u can safely over clock it upto 748 MHz. But over clocking the phone has its disadvantages. So I'd recommend overclocking while playing games whereas keeping it on 600/480 at other times

Yes you can UC and OC this ROM, but as you were told it has disadvantages:
Heating, to mention one. Instability?
If you are using some OC application (e.g. setCPU and similar) that supports profiles, you can enable different frequencies for different cases (screen off, charging etc) so if you're on 729MHz and temperature gets above, say 45degrees, profile can enable something like 600MHz and so on.
I've found through trial and error (actually more error than trial ) that is it not such a good idea to OC this phone beyond 729-748MHz, and it is really dumb to OC beyond it + enable "start on boot" option
So, just in case you finger "accidentally slides" to higher frequency ranges, better have either an "undo settings" flashable file or a recent nand backup...
To make long story short: no real benefit below 300MHz (I had lots of freezes with lower freqs), not much gain above 729MHz (unless you need desperately something to heat the room in the winter ).
Thanks for the help guys
i think stable o.c for our optimus 1 is ranges from 320 up to below 700..
by the way im asking it becoz i will use it everyday..
maybe thats all i think.. hehe

Basically there's not much difference between voltages at 320/480 Mhz. So you can use any of them while among the higher ranges 729 is much more stable than 748.What I mean to say is-take your pick

ok thanks )
by the way, if i overclock it up to 729? it will make my battery much weaker?
and i think if i use wifi or play it will make my unit hotter? something like feeling something in the back? im just curious )

Over clocking above 700Mhz will always produce more heat than normal...and let me say-while playing games or using internet-you will really feel the heat Battery falls much faster...Do not allow increase of temperature above 40°C or it can seriously harm health of battery
PS-Heat can be decreased by opening back cover and exposing to a fan or something.Personally I overclock upto 748Mhz (mostly 729)

Press thanks button if I helped you in any way
OK its final i will overclock it less than 700 )
LOL!
thanks
but i think i can feel the heat in less than 700 hahahaha!
but its ok i will just get the back cover
In the thread it's recommended that, as it is unstable, you shouldn't overclock it and stay the way it is
I don't know if mileage will differ from one phone to another, but mine's set to 320-768. I've kept it that way for the longest time, even before trying out 4WISEMONKEYS. So far so good. If I set it to any other 700-something MHz that's when I feel the heat.
Disclaimer: I realize overclocking and tweaking is very much device specific and what works for one person won't necessarily work for another. That said, I've done a fair amount of reading on the subject but need some clarification on the finer points, along with some opinions on what's working for other people. Most of my questions pertain to the Devil kernel, as most of the settings aren't very well explained. I'm running AOKP M6 with Devil kernel and I've set a modest overclock with 200 minimum and 1200 max, which seems to be pretty smooth and stable. I haven't really felt the need to push it yet
1) What governor do you prefer? From what I read in this thread, SmartassV2 sounds the best and so far it seems to be working okay for me. Also, do the profiles matter (smooth, normal, powersave)?
2) Is it wise to mess with the memory settings in the Devil kernel (zRAM, etc) or should I just leave it alone? What about swap files? Worth the hassle or not?
3) What's the difference between using Live OC and the ROM settings to OC? I've left Live OC alone, and just used the AOKP overclocker to set my values.
4) I know that I've read Deep Idle doesn't work for our phones, but what's the Devil idle setting do?
5) Right now the Screen Off- Min/Max Freq setting is off, but should I set the values for that or does the SmartassV2 governor automatically handle it?
6) Any thoughts on I/O Schedulers? From what I was reading, SIO seems to be the best choice, but then again it seems to be all a matter of opinion.
Thanks for any input you might have on the subject
Alright well I think I'm getting a better handle on this since I've had a few days to mess around, and I'll post some of my thoughts in hopes it might help someone else who's trying to mess with OCing. Problem is that AOKP ICS is already so buttery smooth that overclocking really isn't that noticeable of a gain (at least for me).
As far as clock speeds I've been sticking with 200MHz min 1.2GHz max but might just drop back down to 1.0GHz to save some battery life (I don't really run cpu intense apps that often so I don't really see a huge need). I'm not really going to mess with Live OC now that I understand that it overclocks the bus too... I've screwed around enough with PC overclocking to know that it's going to seriously compromise stability which is a risk I'm not willing to take right now (not to mention it'll probably drain the battery a lot more than 'standard' OCing). I've also found that screen off 400MHz min and 800MHz max works well for me, because although 200MHz min will work too, it lags far too much coming back from standby for my liking.
2 things I still haven't messed with are the RAM settings and devil idle (which I assume doesn't work anyway). As far as the RAM I've never once ran into a low memory issue so I don't really think it's worth the trouble (due to reading this forum post I found).
I changed to SIO for the I/O scheduler but really can't notice any difference from just the default, but I'll keep it set there for good measure I guess.
Well that's it for now, if I notice anything else that might be helpful I'll post again, and if anyone wants to jump in with their experience or settings feel free.
Thanks
Hi,
I just finished installing and launching wildblood 1.1.0(lates ver.) i noticed that it is very laggy even in max CPU Clock 1700GHZ.
Anyone know how to fix, or knows where i can find one.. :3
btw im using stock kernel.

Overclocking the CPU to improve gameplay is pretty much irrelevant unless you just want to keep your hands warm. If you want better frame rates you should overclock the GPU but even still the you shouldn't expect huge results as unfortunately the mali 400mp4 is getting a little old these days and at the stock gpu freq it just isn't powerful enough, but overclocking to 530 or 600mhz does make the game feel more responsive at the expense of the usual trade off with overclocking such as heat and battery life.
Wrong section, post in QA
Not sure if this is the right place.
Basically, Ive been looking around for a way to under clock/over clock the umi z device. I have tried many apps, that say they will overclock and under clock and also ones that say they change the CPU governor. Ive had no luck on this phone. No matter what CPU governor I select it stays on interactive, no matter what minimum and maximum core speeds I select they keep changing and going on/off on their own, and basically anything related to CPU /GPU speed are completely unchangeable. There isnt any custom kernels for this phone, so I was wondering if anyone with the right knowledge would atleast know if it is worth trying and even possible to create a custom kernel for this umi z that allows CPU control. If so I would gladly try myself but I'm not the smartest and dont wanna waste a tonne of time to realize it never would have worked anyway. ALL help is appreciated and politeness even more so, thank you.
