It would be helpful for newcomers like me. Overclocking is allowing your phones CPU to run faster than it was meant to. This obviously increases the speed, but at the cost of more battery life being used. All phones have unique CPU's and so people can overclock to different amounts. To overclock, you need an overclockable rom (flb and Japanese jelly) For jap jelly, flash the overclock.zip And then use something like setCPU or overclock widget from the market. Then, set your Max and min speeds. For flb, only do part 2 as the rom is already overclocked
Guest hugobosslives Posted March 12, 2011 Report Posted March 12, 2011 the above post is a good guide for a beginner. I would just like to add 2 things. 1) to overclock you need a overclockable kernel. these can be obtained by flashing roms such as jap jellyfish and fibble's froyo or a completely new one :D 2) clock speeds are not defined just by model. some blades can get to near 800mhz and remain stable whereas some keep rebooting at mid 600s. just try it out with set.cpu and keep increasing in the smallest gaps and see what you can get to. alot of people find 710 the best
Guest exec Posted March 12, 2011 Report Posted March 12, 2011 And don't tick "Set on boot" in setcpu before you know that the phone is stable.
Guest thunda Posted March 12, 2011 Report Posted March 12, 2011 Can you shorten the life of your phone doing this.
Guest GX390 Posted March 13, 2011 Report Posted March 13, 2011 And don't tick "Set on boot" in setcpu before you know that the phone is stable. Even if you do do this and the phone crashes it default the values anyway
Guest aequalszero Posted March 13, 2011 Report Posted March 13, 2011 Can you shorten the life of your phone doing this. I mean, potentially right? Overclocking can lead to increased heat which could lead to a shorter life. In the end, though, it's a small factor in a number of things that could go wrong with a technological device that resides mainly in bags and pockets, and has to withstand the daily traumas of the outside world. From what I've read - the worst thing that happens if you try and overclock too much is that your phone will crash and you'll need to reboot.
Guest That-Guy Posted March 13, 2011 Report Posted March 13, 2011 If you haven't looked already take a nosey at the CyanogenMod 7 ROM. It has overclocking options built in so no 3rd party apps needed :D Its also a very fast ROM anyway, especially for games!
Guest gremlinman Posted March 13, 2011 Report Posted March 13, 2011 Safest min and max CPU set?? Isnt it max 790 or somthing like that? Not sure about min though?? Anyone?
Guest gremlinman Posted March 13, 2011 Report Posted March 13, 2011 Mine is overclock to: 729.6(MAX) 672(MIN) Not one reboot yet (1hr Later)
Guest HMZX Posted March 13, 2011 Report Posted March 13, 2011 (edited) Safest min and max CPU set?? Isnt it max 790 or somthing like that? Not sure about min though?? Anyone?

Guest PeterLeics Posted March 13, 2011 Report Posted March 13, 2011 My 'phone is only stable at 652 any higher and it locks up.
Guest Swimmerboy Posted March 14, 2011 Report Posted March 14, 2011 Mine is overclock to: 729.6(MAX) 672(MIN) Not one reboot yet (1hr Later) Not the way to go about it unless you want to run your battery down. I'd set min as low as possible (128MHz) in order to have decent usage between charges and set Max as high as your phone can handle without freezing/rebooting. The Max and Min values let the phone know what range to run at - it'll scale it up under load and drop it down if you're not using it again. Setting the above will have it running at 672MHz even when the screen's off and it's in your pocket.

Guest Amphoras Posted April 2, 2011 Report Posted April 2, 2011 Thinking of overclocking my phone, but just wanted to check about it first. If I overclock it, as long as it doesn't reboot, freeze, get too hot this means that speed is stable? I also noticed different governors like smartass, ondemand, etc. whats the difference between these?

If I overclock it, as long as it doesn't reboot, freeze, get too hot this means that speed is stable? I also noticed different governors like smartass, ondemand, etc. whats the difference between these? erm yer kinda. if you overclock and the phone doesn't freeze/reboot when you make it work (i.e when playing cpu intensive games or simular). this means the speed is (relatively stable) keep in mind, getting too hot doesn't mean the speed is unstable it just means its getting too hot. even non-overclocked phones get too hot. its just when overclocking this can happen quicker. In setcpu you can set a profile for when the temperature gets above a certain point (eg 45C) it stops overclocking the cpu. The different governors, are pretty self-explainitory: Governers, govern the cpu (funny that B) ) the name really tells you how. for example, on demand will quickly scale up the cpu speed (i.e to the max) when it is needed, and then scale it down to idle (i.e to min) when nothing is really happening. performance basically keeps it really high all the time. Whereas governers like powersave, and conservative, try to keep the speed low and scale the cpu speed up slowly to increase battery life, but decrease snappiness. Basically..... i recomend 'on demand' (for normal use) its snappy, but also is good on the battery. happy overclocking :D
Guest iKrautDroid Posted April 2, 2011 Report Posted April 2, 2011 Ok, when I overclock to 710 my phone reboots every 15 miutes or so. Is there anyway to make my phone able to handle higher speeds?

Is there anyway to make my phone able to handle higher speeds? haha, wouldn't we all like to know the answer to this!!!!!! as far as i know...... not really. there are little things sum people do, like put a thin sheet of metal behind the battery under the cover to disappate the heat more evenly, and more quickly. (but this makes your wifi signal pretty weak) generally, no you just gota live with it. somepeople are stuck on the very low 600s and still have reboots, so count youself lucky if you can get anywhere near 700.

So the reboots are caused by the battery "overheating"? And I think Ill try the metal thingy. But which metal do you recommend? Does anybody have a picture of this?

Does anybody have a picture of this? No the CPU overheats or just cant handle the increased clock speed as its not getting enough power and crashes.
Guest stylezuk Posted April 3, 2011 Report Posted April 3, 2011 (edited) yeah thats true keeping it at a high frequency makes your battery DIE!!! change it to MAX: 729 MIN: 122 so your phone can slow down and not waste battery if you need to before you complain about the terrible battery life... Have pretty much set up the same except can't push 729 0nly 710 stable, another thing is the profile options in set cpu so have screen off min-max 122 so as even when pushing all social networks etc the cpu isn't kaneing juice. Edited April 3, 2011 by stylezuk
Guest Snipperdag Posted April 3, 2011 Report Posted April 3, 2011 I keep mine at 691Mhz Max 122Mhz Min, only seems stable under Set CPU 2.10 though. I do a lot of rom changing and the No Frills o/c tool just doesn't seem stable enough on my device on any of the SS/CM roms that I try out regardless of governor used. (flb 11b is what I restore back to after each test)
Guest iKrautDroid Posted April 3, 2011 Report Posted April 3, 2011 Wow, I was using setcpu 2.0.4 and my phone started having random reboots @ 710mhz. Now I updated setcpu to 2.1.1 and now I can set to 710mhz without reboots! Cool!
Guest DannyDanny Posted May 2, 2011 Report Posted May 2, 2011 so using different versions of setcpu can change the maximum mhz?? I am using default overclocking preinstalled in CM7. max at 690 I am tempted to try set cpu and see if it can do better... But if I do, do I change max and min mhz in both programs? or just change set cpu and leave cyangenmod to default?
Guest hugobosslives Posted May 2, 2011 Report Posted May 2, 2011 when you change it in setcpu. you will find it automatically changes in the cm7 settings. so no need to worry about conflict.
