[Q] Overclocking - Pros and cons - Optimus One, P500, V General

Hi All,
I am writing this post to know what are the pros and cons for overclocking the phone. I know it helps to increase the clock rate, however if the phone can support it, why didnt the manufacturers made it that way.
And if we do it, are there any chances that the phone might blow up and stop working or something.
I tried to search on this topic but cudnt find anything.
please reply
Iam using LG Optimus One
Thanks !!

Hello.
The main plus is the increase in productivity phone.
The downside is that, theoretically possible to burn the phone, but I repeat it theoretically.
I myself have clocked the phone and nothing terrible has happened to him.

I don't think anything's going to burn as kermel always goes in panic if it can't handle it.

The processor won't burn, as 4silvertooth says the kernel will panic and you'll end up in an endless bootloop; 729 - 748 mhz is safe, 800mhz in most cases cause the kernel to panic.

Well oc has nothing to do with proceesor (don't laugh). Well at hardware level the clock (MHz) and processor are two different thing the crystal provides the MHz to processor and in return it computes at that speeds. So by oc we are telling crystal to oscillate at higher frequency. So if our processor can't handle higher frequency it tells kernel get lost I am not doing this for you as I am not able to execute instruction at such speeds. And all the governers are nothing but a rule for processors to execute tasks. Like if you select performance governer it tells CPU to execute at Max speed you have set. So what ever you set the min frequency it always uses Max speed no need to change min if u r using performance governer same for powersaving governer no matter what you have set for max it always work on min. So all the governers has different sets of rules.
Pros: CPU speeds up the execution
Cons: Crystal may get hot.
Bye.

No you wont go in bootloop.
Let me explain.
You will go in boot loop if you have set speed that processor can't handle and selected set on boot option. As the processor can't handle it and you are telling it to be always in that mode. Dont select set on boot. After reboot manually select oc. The second reason would be currepted filesystem as after kernel panic your phone has rebooted with unsaved changes chances are that filesystem table is currepted. Theres a command to check that I forgot name its like chkdsk for Linux. But no rom impliments that on unhandled reboots.

[Q] SetCPU & Megatron

I tried asking this in the Megatron-thread but as usual, no answers...
I am a little worried about keeping my phone overclocked at all times, so I was thinking about downloading SetCPU and switching between 600 and 700 via that app. But my question is this: Megatron ROM overclocks the phone by default. If I download a 3rd-party app to overclock/underclock the phone, will this mess up the whole system?
Anyone? Would really appreciate help!
i've been using megatron & setcpu together for the past month.. no issues yet, so cant promise ma phone wont go up in flames i clock extra if needed
Ok, thanks!
My Experience: USing LOL rom with default OC gave me kernel panics ...so instead i disabled OC in ROm and wud then OC using SetCPu...ALso I dont know why but touch feels a lot more smoother on LOL rom with the lag fix than megatron....so i switched from megatron to LOL...Currently even with maxCPu 480Mhz and conservative profile..touch is very smooth on LOL

How do I disable the OC in Megatron? By adding the "minitron" file and then using SetCPU?
Hi all,
I'm a newbie in Android world. Successfully flashed my O1 to Megatron v1. Afterwhich I tried installing SetCPU to it and overclock to 806mhz & above. However, after overclocking with SetCPU, the whole phone's performance became more sluggish than the original Megatron 729mhz...
Someone please advise me on how to overcome this and make the phone speedier with high frequency.
Is there a way to edit some of Megatron's kernel to make it 806mhz on default even without using SetCPU?
Don't use set on boot feature, it will make ur phone get stock on bootloop...
So can someone tell me how to proceed with this? I want to be able to change between 600 and 700, when I please. Thanks

Got it! Tried last night without set on boot feature. Working fine with 806mhz and speedier than 729mhz. However my chipset refuses to go into higher frequency without freezing and rebooting... Is it due to my microsd card? I'm still using the original 2gb microsd card tt came together with the O1... Will changing to a class 6 or higher microsd card let me clock higher? or my chipset is just lemon at 806mhz?

FnH84: I downloaded SetCPU from XDA forum and can tweak the frequency between 600 & 700 by myself. Even can set profiles to govern the speed at different situations.

You are already pushing the CPU to its limit with that 806 MHz frequency. Do you even realize is 34% above the designed specs for this CPU? You're already lucky enough you got it stable at 806, and no SD card will ever make a difference, they're not related.
How come Samsung Galaxy Mini running on the same chipset offer 800Mhz as stock???
Man, I don't know! How come the same "Pentium IV" processor could come in speeds from 1.3 GHz to 3.8 GHz?
Can any of you actually believe that LG would underclock an 800 MHz CPU and sell it to us as a 600 MHz instead of letting it run at its best?
Galaxy Mini is obviously using a CPU designed to run at 800 MHz, even though it bears the same name. And that one can probably be overclocked to above 1 GHz.

Thanks for your reply. I was thinking bout the same as the other guy, that galaxy ace can run at 800mhz, and why not O1.
Hmm... Isn't there any other ways to push the frequency higher? Maybe supply more voltage to the core? I dont mind sacrificing batt life, I just wanna try ways to push it to the max~~

Optimus finally may have flash

Saw this article today that indicates qualcomm is working with adobe to bring flash to the msm7x27 chipset.

These are really great news. I hope we will get flash as soon as possible. Let's see how these things will go.

Sounds like it may be hardware accelerated. Hopefully it is because my nook with an a8 CPU at 1.2ghz has issues playing 480p flash videos without hardware acceleration. Would imagine my optimus overclocked at 806mhz would have issues with 360p flash videos without hardware acceleration.
Good news but how will we get 800mhz on O1???It should be possible bcoz if not how Sam Ace & Gio are running on that speed!!!

You probably will not. 768MHz is completely stable here though, anything above that => not good.

Well, sometime you can get 800MHz. But overclocking is strange device dependent. So, somebody have 768 very stable you, but somebody can have 800 and somebody have some problems also on 710 like me for example.
I believe the ARM1176 processor is designed to 800 MHz for my LG Optimus V.
Not sure that everyone else is running the same processor, but I think there are two speeds for the ARM v.6, all flavors, which is 800 MHz and 1GHz. The cell manufacturers lower the speed to conserve power and I'm certain buy the less expensive 800 MHz version.
So everyones CPU should be 800 MHz capable...that does not mean that the memory I/O can take a similar speed up - I don't know exactly what is being sped up with the CPU overclock, but the CPU itself shouldn't have any issues. If it is the system clock, then the I/O is already being timed appropriately and a speed up is overclock for it, but 800 MHz is not an overclock for the CPU.
Good news people let's wait and see...
Nice! I have been waiting for this from long time ago.

it is possible but for most peoples ROM anything past 787 will give a kernel error and reboot the phone the only ROMi got it to work on was Megatron ROM
Sent from my LG-P500 using XDA Premium App running miks CM7, quadrant 2100, over clocked at 787
On Spica Max Neocore output was 7 fps and on o1 its 63 fps currently.
Even than I could play games like ninjump and mx moto.
So what difference would be there in performance even if we can clock till 768-787 and not 806.
Will the flash not run because our clock speed is 787 and not 800?
I hope people are getting what I am asking. When our o1 can handle things like Neocore 63 fps, 1gb ext partition, multi format video playback, then why would it be difficult to run flash on 787 instead of 800 even when flash would be optimized for our kind of processors?

Awesome news. Hope we get it soon.
More or less flash should work on or device even at 600mhz, the real issue is to optimize it for our chip set instructions.

Exactly. And even if there was a way to run flash on O1, I wouldn't bother with it myself. It would only slow down the phone and kill the battery life in two seconds.. I really, really don't understand what the big deal about this is. Low-budget phone, no flash. End of discussion lol.

Cpu freq.

Ok, I got one question... Is it ok to use max default cpu speed (if I'm not overclocked). 1024... Or should I put a lower amount...
Sorry for my bad English.

As for me, 800 MhZ is enough for comfortable work.
Overclocking is needed only in "Heavy" games.

1024Mhz is stock speed and yes its safe to use.
If you using your phone only for calling/sms...then 800Mhz is enough.
For calls you can eaven use 600 and if you have your rom rooted you can set the voltage a bit lower.
But from my experience you can easy use the 1 ghz freq and the battery lasts long if you donĀ“t use much your phone.
Neo works fine at 1.4 ghz from performance and battery.
If you use sio i/o and lagfree.
Depending on your CPU you could undervolt it at 1ghz and achieve the same results as it is on 800mhz. But yeah 1ghz is efficient enough just stay away from Live Wallpapers.
i run on stock tweaked perfect battery live on 1024 Mhz

Even devices with 600-700mhz is browsing web, watching YouTube, have live wallpapers, playing music, record videos......and etc
So why not use our phones too 700mhz
Please guys don't forget...minimum CPU with rooted phones have 122mhz
If they work even so low frequency...why not 600mhz....or up.
Edit. I'm using 122-1300mhz, screenoff 122-567mhz smartass/all frequency voltages lowered -50mV.

thanks bro for the tip to settle it low when screen is off, maybe thaT is more saving battery life, and i hit that button

Is it safe.

Hey, i overclocked my ace 2 to 1100MHZ my question is, is it safe to keep it on maximum at all times?.
1100 MIN and 1100 MAX
Thank you.
That's probably something you shouldn't do as a "full-time" clock speed. Remember, your CPU's scaling frequency is determined upon load called upon from system process, applications, and so on. When load is minimal, the CPU scaling frequently will fall back to lower table speeds, and spike to higher when necessary. Having no "resting" frequency will cause: more heat generated from the lack of these lower frequencies, shortened battery life expectancy, and possibly shortened CPU lifespan.
Unless you're using a governor setting of "performance" or the like, your CPU's governor will step down through the kernel's frequently tables as determined by the load. Again, unless you're running a governor setting that does anything but what is similarly done with mot_hotplug the CPU's core(s) will be turned off when not demanded.
Be kind to your CPU, give it a break. I can't imagine any reason to clock to such high values to run all the time. Don't you put your phone to sleep ever? Why would you want the CPU running at 1100MHz while sleeping? Doesn't seem like a logical idea to me...

No worries. Just don't want to see you fry out your CPU by not giving it the ability to have 'downtime'.
Edit: You can even change the scaling frequency at echo 0 to a lower table value, to give even more ability to "rest". If you need any more info, don't hesitate to PM me. I've done a lot of experimentation with overclocking over the last several months...

MiniCM10 Processor Settings

Hello,
I'm writing this thread to know which processor options would be optimal in our minis. The best settings, which give me the best performance/battery, I've found are:
CPU Governor: SMARTASSV2 (Default)
Min Freq: 19MHz
Max Freq: 748MHz
Undervolt: TRUE
I'm also using Apex Launcher. Which settings are you using?
Note: This are just my results, be careful when you change your processor settings.

Because it undervolts on every frequency below 600, and his minimum is 19, so when the phone is idle or doesn't need all of the processing power he saves battery
The SmartAss governor is very good at picking the right frequencies for any given job, so it doesn't allways run on 748Mhz, not even when you're using the phone.

That is the same very purpose of SMARTASSV2 to undervolt your device when idle or on sleepmode and overclocks it when on process. So ticking the undervolt wont affect your device because the one that manage the frequency will be the COUgovernor.

The SmartAss Governor only governs the frequencies, not the voltage that the Processor uses. there is a difference between the speed the cpu runs on (Mhz) and the amount of Electricity (Volts) it gets fed
Say Qualcomm has said it needs 5 volts to run at the stock frequency of 600Mhz, then the processor will always get 5 Volts, no matter which frequency it uses.
Undervolting will feed it less than the 5Volts when the frequencies are lower, SmartAss won't do that, it will run the 19Mhz still on 5Volts.
(Voltages are examples, i don't know the exact values, but I know that running on 122 or less will be stable on less than half of the nominal power)
