I need a small advice please: when Im set in CM setings minimum cpu speed at 245 Mhz so why goes my phone to deep sleep after locked screen? I see it in cpu spy app.. Or its quite normal? I dont want it if its possible... I want to stop cpu speed only at 245 after locked screen... its somehow possible?
I am using for this regulating only CM performance setings... When I use cpu master I put there the same setings but the problems where still the same so i uninstal it... for information I was using kernel for overclocking cpu... maebe there was problem, but now kernel is back to ketut lenovo8 without OC... problem is still here...governor is set to "ondemand" - i have tryed all types of governor and everytime there was in cpu spy deep sleep after locked screen...
before with oc kernel:

You don't want deep sleep?! You prefer it to run at 800 during sleep so you get less battery life?
deep sleep only occur when on lower freq, trigger by cpu governor. but it differ from a governor to another. some cpu governor trigger deep sleep on 128mhz, some on 348mhz and so on. so if u wanna disable it, just make ur cpu always running at highest possible speed all the time. but why in the world would u wanna do that? good luck frying ur cpu that way
Deep sleep is good for your phone. To be honest people are looking at ways to have it as high as possible.
Ok then why on froyo wake up = 0 sec?

To all: I dont want to run at 800 when theres normaly deep sleep in locked screen... I want to run only at minimum freq like 122 or i think its better at 245... but i dont know how to do it...
When i set it in cm performance in cpu minimal speed at 245 it goes than again to deep sleep wheen i locked screen - the question is why and how to change it... or do somebody know in what frequency runs deep sleep? Its lower than 122? sorry for my bad english

I think deep sleep is a state. It runs at that frequency at an idle state. This is probably in contrast to partial wake which means the phone is running apps while the screen is off. So don't bother trying to disable the deep sleep state there is no point. the wakeup lag has nothing to do with frequency, i've experimented.
So ig its state there is nothing what to do... I dont want faster unlocking, i want only know what frequency use deep sleep... im afraid that is less than 122 Mhz... its good for battery but not for fast wake up from this sleep... if i will have a faster phone so thats more important for me than a one hour less of battery using in one day...
Edit: so some news from anybody about this "problem" ?

With talk of late about smooth scrolling and step time between frequencies I got to thinking. What draw backs are there to running at 500mhz with the performance governor?
I know that means it's forcing 500mhz when it could be 200mhz. And while ideally the processor should be as low as possible, 500mhz is pretty low.
But the phone has really felt so smooth! Scrolling is near jitter free and things seem to open much quicker, average smaller things, not intense games obviously.
With screen off deep sleep should be no problem. And how many times does the phone drop down to 200mhz while in use? If I'm not using my phone the screen is off. Seems the the extra battery spent would be made back up by it not going over 500mhz.
So I guess my questions are: Has anybody tried this for am extended period of time? And/or is there really that much processor strain by forcing 500mhz during use?

Huh? Performance governor fundamentally fixes the clock at maximum stock speed (1.2 GHz).
Do you mean setting the minimum for ondemand/conservative to 500 MHz when the screen is on? I do this on my device. When the screen is on, the power consumption difference between 200 MHz and 500 MHz is very small, especially thanks to cpuidle, which gates the clock when the CPU is not loaded, eliminating most of the usual linear contribution of clock frequency to power consumption.
Processor is set to 500mhz max 200mhz min with screen on.
The governor set to performance to keep it at 500mhz while screen is on.
If power difference between 200 and 500 is not that big, then that's how I'm going to leave it for now. Everything has been very stable. No slow downs on normal phone operations, no force closes, no sod's, or soft reboots.

Performance governor fixes the CPU at 1.2 GHz... Not sure what you're talking about.
Not sure why you would want to downclock your device so much.
If you move the max slider in setcpu to 500mhz and set the governor to performance, it pins the CPU at 500mhz, not 1.2ghz

Yahtzee!...er, correct
And so far everything had been great. Stable, no freezes. I did undervolt it pretty low @ 500mhz (dropped it 75mv) and it got choppy. But upped the voltage 25mv and been silky smooth ever since. Battery life hasn't seemed to be effected much. I was hoping for more but aiming to break even. I'm ok with same battery life.

I'm running miui, at 500max on performance I see skyrocket class jittery performance. Maybe its miui vs stock based that's giving that difference. My phone spends most of its time at 500 when not charging or deep sleep, according to CPU spy. So the difference in battery should be minimal, but to me the difference in performance is very noticible. YMMV.

Hehe, you're doing the exact opposite of me - I have things set to conservative with 500 MHz minimum when screen is on.
(Why? Because the diff. betwen 200 and 500 in terms of power consumption is far less than the baseline power consumption of the screen.)

500mhz starting giving me issues. Switched to 800mhz.
Had the phone heat up pretty hot one time. I'm guessing the cpu limit somehow didn't kick in. So instead of performance governor keeping the phone at 800mhz, I set the high cpu limit to 800mhz and the low cpu limit to 800mhz. Since that is now keeping it at the speed I want, the governor can be set to conservative, or whatever you want other than performance, and I don't have to worry about overheating or excessive battery drainage if something goes wrong again.
So far it's been working great. Haven't noticed a change in battery life.

Hi friends,
I wanted to ask that does overclocking damage the mobile processor and decrease its life in any way. I want to use a Megatron rom but i am afraid to do so, kindly help me out.
Another question i wanted to ask is how to check if my mobile is running baseband or new baseband.
I have LG Optimus One Android version 2.3.3 default rom.
Regards,
Pravin
If you installed GB via official update,then you have new baseband.
About overclocking:
Every processor support a max frequency.Mine supports about 710 mhz.But,I overclocked it to 806,put the phone on "set on boot" and it kept rebooting for 5+ times.However,this didn't affected my processor.I don't think that overclock can damage your phone in any way.Also,until 729 mHz you'll get the same battery performances as at 600 mHz.Just OC until 691 mhz first time and play smth for 5 minutes.If it doesn't reboot( also know as KP = kERNEL pANIC) , then go on until 710,729,748,etc.Until you get KP.After,select the last working value and enjoy.

I dont think the overclocking can damage the phone, in the worst case it can heat up the phone slightly (which i experienced on stock ROM using franco's kernal)
The worst thing that can happen is that the phone will heat up after 1-2 hours like galaxy s and s2 do in 10 mins...

Problems of Overclocking:
1.Decrease in battery life because we are increasing the voltage output.
2.Overclocking causes heating which can lead to damage to other hardware components and again damage to battery.
But since these effects are very minimal and are hardly noticeable(and in with most kernels, processor usage is controlled by good governors) in our phones there is no serious harm in overclocking and will only improve performance.

Heating is not that bad, unless you are a sick gamer or surfer...
Our device uses same voltage for 122-480 and 600-864, so the battery taken is not that bad...
Edit: the phone NEVER gets over 40°C unless there are 35° air temperature, you hold it very hard in your hand or it has a protection...

Once I broke my phone with KDZ and took it to Service Center...
When I got it back, they said that also motherboard was damaged. I tried to look like a fool and acted that I'm surprised.
I'm pretty sure this is because of OC. Don't use higher than 787mhz.
Edit: Oh, and before this problem, I got GPS lock in 1.5 minutes. Now it's in about 10 seconds.

Yeah thats why i said the effect is very minimal. And higher the processor usage obviously more the battery usage. So with kernels like the original lg one which does not have a very good governor(as far as i know) the processor tends to stay towards the max frequency range and hence higher voltage.
Yes,overclocking 'too much' can damage CPU and battery life.

Conservative is the best stock governor... it looks like interactive actually is much more battery saver than ondemand... which ALWAYS keeps at Max..(this is odd)
I love conservative, I am using it because it takes a minute to get Max performance, but then you have maximum performance... but when you do a short usage and keep minimum frequency at 122, there is a chance you will have no higher than 480...
Also, one thing I recommend is using maximum at 480 when idle and listening to music... phone tends to keep it at maximum always when awake and music in background... and 480 is smooth for small tasks... and really battery save!

OK lets put it this way..
Computers.. desktop for example.. are well known to be overclock..
CPU problems would be.. HEAT. it causes the processor to malfunction, reboots and worst to be cooked..
since are device is to small and 806mhz heats it up not much to burn.. its ok
but? it malfunction.
and overclocking SHORTENs your processor LIFE. that is true
Bad if too much
We are actually pushing the limits of our phone.
Too much of everything is bad..especially HEAT.
Beat the heat...
Battery drain is not a problem just as "vlt96" says.
It can decrease life of your mobile's processor as maufacturers claim.
729 Mhz or 748 Mhz should be sufficient for medium use.
Wha the **** is up with that? I'm actually raging right now.
I play any game for 5 minutes or so, and when I quit it the phone has it's performance basically halved. It goes like this: Run Quadrant Standard -> get 3300 points -> play 3D game for 5 minutes -> game slows down noticeably -> close game ->run quadrant again -> get a score of 1600.
What's up with this crap? It's so insanely aggravating. I restored my phone from PCC and it still happens. The only way to get it running decently again after it starts crawling is to reboot it.
Seriously, I've had it with this piece of crap of a phone. I think this **** crossed the line, I'm selling it.
Hrm i think it's when ur phone get hot and decrease it max cpu frequency to about 800mhz! So try some custom rom or kernels might fix the problem!

I don't have that visible underclocking under CPU Master. Mine always says 1500 as max frequency. It looks like you set it to 800 manually.
But anyway, I think it's related to overheating because I noticed that if I let it sit for a while after running a game performance goes up again.
Anyway, I don't give a crap about what's causing it. A phone should NOT overheat from normal use. Ok, it's summer and it's hot, but seriously, I've had it with this phone.
I can't deal with this. I'll just sell it and go back to my trusty ol' Xperia Ray on Gingerbread.

All high power phones have problems with overheating and becoming slow. Install a custom kernel and undervolt it, that should help. Also using a custom rom and kernel has reduced my heat problem a lot.
Of course your xperia ray doesn't have issues because it is slow. A dual core in a phone is going to heat up.
I have played shadowgun for 30 minutes without any slowdown.

is there any effect of overclocking on battery life or performance on mobile?
more performance but lower battery life.
Mmm ok I have some questions, what is a normal overclock to improve battery life but without sacrificing a lot of performance.
And the other way around, an overclock that improves some performance without sacrificing too much battery.
What are the "optimal" values of an overclock (Without making the phone unstable)
I would just overclock until you get phone instability or you go as far as you can for the current kernel (I'm on AOKP 4.0.4 and it's 787 max which is what I'm at).
Battery life doesn't get affected that much because it's mostly drain when playing games where it ramps up to the max clock speed, at which point you're draining a lot of battery anyways.

Thanks, I also have AOKP so I'm going to work around it a bit, how can I test stability?
Go to Rom Control.. Performance.
Remember to UNCHECK " Set at boot" option.. so that if anything happens.. it can return to default value after a reboot.
If random reboots or white screen appears or phone hangs.. its not stable.
I'll rephrase my question, what type of test can I do to ensure I have a stable overclock. I don't want to find my phone turned off out of the blue and maybe missed an alarm or what not. Thanks anyhow for the tips
Just do general usage. If it works fine for 2 weeks at a specific clock, it's likely to be okay.

You will only know by using. The CPU manufacturers label a chip ancertain speed because it fails a test at the next level. That means that some chips can handle faster than others. They are guaranteed to be stable at the rated speed.

Not necessarily. Voltage and heat are usually what kills electrical components. Since our device can't change voltage for the CPU, that point is irrelevant. However, heat is a factor but AFAIK the heat from overclocking doesn't increase that much for this device, unlike something like PC CPUs so that's fine as well.

I am unsure if this is just over caution on their part of if this is something we need to be worried about... honesty even yours at 39c is not that hot 102 F which for a computer is whatever... but I thought this chip was supposed to run cooler and everything being the new architecture.
I have been doing a lot of CPU testing and noticed a couple of things:
First of all the issue with the screen not turning brighter is simple: the heat within the device reached a certain limit that could potentially damage it.
the CPU, RAM and the screen light are the main culprit. Especially the CPU and RAM, try CPU stats and after heavy use you will notice the phone gets warm/hot and the freq gets capped out at 1.1 GHz by the kernel. This is mainly to reduce the heat obviously....I guess keeping the phone running at 1.5 GHz with all 4 cores and the screen cranked up to max will definitely turn the phone into a Coleman stove in no time.
So i guess this powerful CPU doesn't do any better than any dual core running constantly and stable for the same amount of time to crunch performance levels. Sigh...I guess until they wont figure out to make things run cooler powerful CPU's wont get far-only on paper
Just my 2 cents

You are right on point. I have seen it drop (I believe to 1180) when running a bunch of benchmarks. The manufacturer sets the heat threshold at a very safe level. Kernel devs are usually able to safely bump that up another 10 to 15 degrees. I am one of the lucky ones that got the variant 3 of the international One X. Variant 3 was the strongest version and I ran all 4 cores at 1600 with 51 minimum. Faux usually figures out how to uncap and raise the throttle temperature... but he's on a N4. I am going to keep an eye on the kernel threads there and see how far they push things. Chainfire's "PerfMod" app is perfect to watch this while running different apps
