Overclock, it means to get about 806mhz, and successful overclock means to run the CPU smoothly and fast on 806mhz. Some roms support the overclock, some don't and other roms say they can not overclock with 806mhz but with 787mhz because of getting frezzed, rebooted and so on. But if you look clearer on the CPU and look at time in spare or with the app CPU spy you can easily see that the values 787 and 768 don't run a percent of the whole time. This means they even run with stock speed 600MHz. It even show you first that the CPU run so fast and bla bla.. If someone tell you to run the CPU not with 806mhz because of freezing, graphic glitches don't believe it, if you change it to 767 or something like that it will run with just 600MHz.
That's life dudes, so don't believe everything you see or hear and be carefully

i was told that overclocking could reduce the life of your wfs.
this is the reason why i dont overclock.
i did it once and 3d games started showing glitches.
i would recommend ppl to test and read first before setting it to 700-800mhz.
thats just my oppinion.
I know that all of the cdma oc kernels are absolutely stable at 806. I have indeed never heard of a properly flashed kernel freezing under oc in the wfs. (admittedly I don't read the gsm threads too much) And as to shortening the life if the phone, if you plan on keeping it for like 5 years then sure, it might. But your not going to. Your battery on the other hand...

I agree.
The freezing I wouldn't put down to kernel's.
More likely to be the processor.
Same with desktop processors, you can't expect every one of them to perform the same.
Because one is a great overclocker it doesn't mean that they all will be.
just because they are the same processor, they came from a different yield which may have been better or worse.
By the way I've been running mine at 806 for over 3 months or more with no ill effects.

My phone starts glitching in 3d as soon as I clock my CPU higher then 600. Screen turns purple in benchmarks.. so no overclock for me.

The reason ist often the wrong rom for overclock. I tried to overclock CM7 to but without look, now I did my own rom and here it goes antutu benchmark about 1700
Sent from my HTC Wildfire S A510e with JxMatteo_ROM_V1.1 ROM
I run my wfs on 122/768MHz w/o any problems... On CM 7.2 ...
And its not going to shorten life of device for like idk how long... Phone uses 768 only sometimes, when needed and not all the time... So its not such a stress to a cpu.
But i saw one guy for example, complaining that his phone was hot when he turn off or something, and he did overclock to 768/806... so he is constantly running it over 600MHz... I just wan't to see what will happen in few months or...
I have overclocked my phone with m1ndh4x8r's rom.
It running at 245-806mhz with smartass2 governor.
It runs about 10 days now, with absolutely no problem or freezes.
And after of 3-4 hours of constantly use (browsing games), it just gets barely warmer.
That's my 5 cent
My phone currently run with 787/200 with SetCPU and several custom profiles: 320/120 screen off, 480/200 in call, temp>48,batt<15.
With 806 get some visual glitches, but on 787 it run more than 4 hours of stress test in SetCPU.

Did you read my post dude? I don't think so, if you take the values 787 it will run with just 600! First read the post than answer another thing is that 48°C were absolutely to hot! Overlocking should not be just like a game, it's a science.!

Overclocked rom perform better than stock 600/400 even in phone shell itself, removing visual lags. Try and you will see it.
And there are still games..
With such reasons there are no need to buy new CPU for desktop because 99% of time it idling

matt5eo, that info you posted isn't 100% accurate. Overclocking is in fact a science and if you rise the CPU speed, a benchmark should present better results. Right? So let's see some science applied.

I couldn't test the other governors now because I ran out of battery...
Anyway it's a waste of time because as we can see the score rises consistently with the selected CPU speed.
The CPU speed used at a given time depends a lot on the governor and on the I/O scheduler you choose.
From what I saw the governor can make the huge difference between the CPU speed increases and decreases. With the performance and interactive governors Quadrant showed the real clock at which the CPU was running (on System Information) and it was consistent with the maximum clock I selected on No Frills CPU Control.
When I selected 787MHz, the actual speed was in fact 787MHz and not 600MHz like you say. The same happened with the other clocks (600, 768, 806).
So what you write might apply to some kernels but definitely not to all.
I don't have the time to put nice screen captures here but I certainly have no interest in inventing scores and contradicting someone just for fun.
Just wanted to let you know my results.
This is off topic but i'll write it here anyway.
I don't have enough posts to post on your thread on JxMatteo_ROM_V1.1.
Thank you for the rom, it's very good.
I was about to get rid of this phone and buy another until HTC unlocked bootloader, your rom made my phone perfect.
Like the font also. Is there some way to change font to something else?
Been wanting to try the Airwolf font, might be cool...

Have a quick go at this people - run an oc kernal such as CM7 or something and overclock to 806mhz. For a few hours, do it.
Then switch off your phone. Remove the battery and SMELL IT. SMELL it like you mean it. I'm telling you SMELL it, FEEL it. It smells like one of those electric car toys and it feels relatively hot. I can smell it immediately, I don't even have to go close to the phone. a little scary tbh. however, my phone has had no problems at all, God forbid on 806mhz, so I leave it at that.
I don't think it's that bad for your phone's lifetime, as most of us will not own this for more than two or three years, I'm sure. It might even be healther at times to underclock the CPU most of the time when not using it. This must balance out the effects, right?

you can change font by making you own theme, with UOT KITCHEN.
if you lest say want just to change font, just choose font change, no need for anything else, and it will update theme with only font ... you have it all in how to ... good luck.

I'm on SmartassV2.
I once asked this same question ot DoomLord, maker of DoomKernel about which governor and IO to use for best gaming and all around performance.
His recommendation (whihc I have been using since and saw a noticable difference) was to use
Governor: Performance
I/O: BFQ
and I overclock mine to 1.2ghz. My first android phone i oc'd too much, heard a popping noise and BAM.....bu-bye. So I dont go too far..
I generally step up the speed one step at a time until I hit errors that cannot be explained or I get force quits because the phone is running too fast. I suggest going slowly and testing things out but using the governor Performance while the phone is changing. Right now I'm doing okay with smartass v2 at .60/ 1.5 ghz. I might try bumping it up to 1.6 ghz and see how that works tomorrow.

I know I'm mad late, but I was wondering why my phone kept rebooting. I uninstalled all overclocking apps so I thought my profiles would return to normal. Turns out I must have accidentally set the profile to 2ghz max and 2ghz min somehow. My phone was super lagging and thank God it didn't burn out, smh...

Hey guys ive already overclocked my phone using the lubus gb kernelv12 and i gota say having the extra internal memory (EXTRA 400MB!!!) and the ability to overclock to 1.6ghz is nice, however there are some things i wana ask. Im running at a min 249 and a max of 1613 mhz using no frills cpu with smartassv2 as my governer and noob as be scheduler, it runs miracles in speed, everything i can run at high resolutions and play and top speeds. However i leave my phone like this all the time ( 249mhz 1613 mhz). The smartassv2 governer is ment to only use high cpus when needed, so that in theory means that i wont always be at 1.6ghz. Ive read on other forums keeping your phone overclocked all the time is bad and dangerous but is it really if the max cpu is only being used when needed? In otherwords should i leave it how it is or is it dangerous? My device is an xperia plat btw. :victory:

AFAIK only the Performance gov keeps the phone at the max allowed clock speed (1.6GHz in your case), so it's just fine as it is. You could, however, use an app (the only one I know that does this is SetCPU, there might be others) to make profiles so it'll only be overclocked when playing games/running benchmarks et cetera. This might save you some battery life.
CPU master by antutu allows you to set profiles but you need to buy the pro to do it

these settings proved to be stable on all roms and frequencies ive tried (even 1200MHz).
and as for the governor, ive found that boosted uses vsel3 too much, so im on smartass, this drains the battery the least imo.

i am trying interactive governors beacuse of the below mentioned ..... let me try for 2-3 days , if you wanna try check out
off from smartass coz ---but after test lets see who comes up good
Smartass:
Result of Erasmux rewriting the complete code of interactive governor. Main goal is to optimize battery life without comprising performance. Still, not as battery friendly
Interactive:
Can be considered a faster ondemand. So more snappier, less battery. Interactive is designed for latency-sensitive, interactive workloads. Instead of sampling at every interval like ondemand, it determines how to scale up when CPU comes out of idle. The governor has the following advantages: 1) More consistent ramping, because existing governors do their CPU load sampling in a workqueue context, but interactive governor does this in a timer context, which gives more consistent CPU load sampling. 2) Higher priority for CPU frequency increase, thus giving the remaining tasks the CPU performance benefit, unlike existing governors which schedule ramp-up work to occur after your performance starved tasks have completed. Interactive It's an intelligent Ondemand because of stability optimizations. Why??
Sampling the CPU load every X ms (like Ondemand) can lead to under-powering the CPU for X ms, leading to dropped frames, stuttering UI, etc. Instead of sampling the CPU at a specified rate, the interactive governor will check whether to scale the CPU frequency up soon after coming out of idle. When the CPU comes out of idle, a timer is configured to fire within 1-2 ticks. If the CPU is very busy between exiting idle and when the timer fires, then we assume the CPU is underpowered and ramp to max frequency.

i am trying interactive governors beacuse of the below mentioned ..... let me try for 2-3 days , if you wanna try check out
off from smartass coz ---but after test lets see who comes up good
Smartass:
Result of Erasmux rewriting the complete code of interactive governor. Main goal is to optimize battery life without comprising performance. Still, not as battery friendly
Interactive:
Can be considered a faster ondemand. So more snappier, less battery. Interactive is designed for latency-sensitive, interactive workloads. Instead of sampling at every interval like ondemand, it determines how to scale up when CPU comes out of idle. The governor has the following advantages: 1) More consistent ramping, because existing governors do their CPU load sampling in a workqueue context, but interactive governor does this in a timer context, which gives more consistent CPU load sampling. 2) Higher priority for CPU frequency increase, thus giving the remaining tasks the CPU performance benefit, unlike existing governors which schedule ramp-up work to occur after your performance starved tasks have completed. Interactive It's an intelligent Ondemand because of stability optimizations. Why??

great buddy, from my side i can say that my battery is going good and the system is still stable, also i tryed die hard battery script and i have 12 hours and 40 mins of use with 49% of charge, before my batt was dead in 4 hours :/

How to Change Governor
Hi people, i'm interested in trying the smartass governor.
I'm with a Defy+ (MB526) with Quarks CM7.2 ROM . In bootmenu i found smartass and selected it, but when i boot android and enter on setvsel (ou antutu cpu master) both says i'm with ondemand governor.
Can someone help me changing governors? Sorry for the n00b question, but i couldn't find how to do it.

in quarks cm 7.2 in the system/lib/modules folder are the cpufreq_... files? if they aren't in there u can't switch to this governors
look here
Defy mit Android 4.0.4 CM9 RockZ
1st,
What is the best cpu speed for great performance and excellent battery life???
2nd,
What is the Best Governor for battery life and performance???
3rd,
What is the best IO Scheduler for battery life and performance?
I know there are a lot of threads with these questions, but they didnt have the best answers.
Im currently on 356mhz min and 1.3ghz max with governor performance and IO scheduler sio.
Hahaha.. Every Q u've asked depends on the phone. But i think this is the setup for every1 & infact almost every rom had this setup by default.
Governor: smartassV2, ondemand
I/o : sio, deadline
Freq : min-200Ghz, max-1200Ghz
Kernel is up to u. But fyi, its not all up to the kernel. The rom hav thier own role to achieve whats best. Again, everything's depends on the phone.
I prefer the governor badass. Performance locks it in its highest clock speed, so it´ll go through your battery really fast. As for the overclock, I have it at 1600 when gaming and 1200 when not gaming (SetCPU).
ok.
I have been searching for some time and i am yet to find any details on bcm21533 governoe for galaxy y.
In my experience it gives performance nearly as much as smartassv2 and gives battery life same or better than ondemand. i find it faster than interactive.
Yet i have never heard of anyone use this governor. anyone know why? isnt it far better than smartassv2 on our phone?
Have tried this governor ornhells fusion and percy kernel.
Indeed it works as this :
Only switching between max and min processor values (832 and 156 for example) depending on needed work, but maybe you are using some heavy app and speed = min it will be laggy , and light app on max freq will be battery drain, so interactive is better for me
I use kuro kernel with
Gov Ondeman
i/o noop
stable for me
I always used conservative and sio, never complained about this
