go to recovery.choose cpu and there will be values,clk1 clk2...clk4
these are the clock values,update them to whatever u need.and set the vsel accordingly,in vsel1 ...vsel4 respectively

I know how to, but I'd like to know safe values first. What happens if I set something wrong?

Use vsel calculator app.will give u optimum values.u can test them by lowering ur vsels 1 ir 2 points at a time .if u lower them too much.the phone will reboot randomly.if u increase them too much.there is a risk to burn the cpu.

I use 300/17 600/32 800/42 1000/52 without problems. To get the vsel I do frec/20+2.

How can I prevent burning my CPU? Is Vsel Calculator safe?

Stay within the safe clock frequency.less than 1300mhz.u wouldnt need dat much.defy is pretty much lagless on 1100mhz.and always set vsel less than tha omtimised value.vsel calculator is perfectly safe.doesnt do anything.just tells u the optimum safe values of vsel corresponding to the clock value by a formula.just simple calculation.nothing more

Calculated:
CPU Freq Recommended Voltage
1100 MHz 57 +/-2
800 MHz 42 +/-2
600 MHz 32 +/-2
300 MHz 17 +/-2
So I should set frequency 4 to 1100 and vsel to 57, right?
And what are Vsel and Recommended Voltage?

Yup, you got it right. Set vsel 4 to 57±2... and freq 4 to 1100.
Vsel is CPU voltage... this is the recommended voltage for the freq u selected.

WAIT... I went to Bootmenu CPU settings and Vsel values are different from Vsel Calculator.
Clk Vsel
300 MHz 30
600 MHz 46
800 MHz 54
1000 MHz 58
Why are they different from Vsel Calculator values? Isn't it dangerous to change voltage values? What happens if I set a totally different voltage?
Sorry for the questions, I'm not an expert of OC...
EDIT: I searched online and I found that voltages are high by default because CPUs are stable at different voltages from phones to phones.
How do I safely determine my CPU's stable voltage without damaging the hardware?

I think you can use the vsel=freq/20+2 formula.
It's always working for me and stable!
My current values 300/17,600/32, 800/42, 1100/57

Its different from vselcalc bcoz it only calculates and estimates that your hardware will run ok with these values.doesnt mean that its your actual values.
You can select any one clock at a time.and lower its vsel by 1 or 2.than reboot into system.and check if it is stable.like you dont face any fc.and reboots.this way your hardware will not damage.and you can find optimum values.if it reboots.simply increase the corresponding vsel by 1 or 2.just try not to go beyond vsel 65.it will not burn.but its not safe.so try to be within 65.. its not that hard.give it a try.i hope this clear things up for you. :thumbup:

I set Clock 4 to 1100 MHz and leaved Vsel to default (58). I saved and booted 2ndboot from bootmenu, and CyanogenMod boot animation showed for a while, then black screen. I removed and inserted the battery and it booted successfully. I played Subway Surfers so I think it's stable, but animations seem slower. Maybe Vsel is too low?
And is it stable at 1.2 GHz and Vsel 62?
EDIT: it's not very stable, it rebooted in the app drawer....

Animation doesnt depend on your vsels...and its safe to go for that.but it wont be needed.1100 is more than enuff

Two more things: which settings does Bootmenu use? If it uses my settings and they are not stable how can I enter bootmenu?
And I read in the user's manual that if the phone heats too much it shows a warning and you can only call emergency, does it apply only for stock ROM or also for CM10?

I know how to enter bootmenu, but if I set a totally unstable Vsel, the phone should always reboot, so it would be impossible to restore default settings, right? Or does bootmenu use different settings?

Underclocking?

Why is my aria automatically underclocking itself everytime I lock my phone?
Sent from my HTC Liberty using XDA App
Since we're on the subject, does anybody know what mHz the arias cpu underclocks to when its screen locked/screen off (with NO music player or calls or anything like that going)?
245Mhz if I'm not mistaken.

Just to confirm. My CPU stats show:
245.76 mhz 74% of the time
480 mhz 20% of the time
600 mhz 6% of the time
manojsuper said:
Because it saves battery and tries to keep the battery maintained at a constant temperature. Your phone works through the "ondemand" mechanism...when ever you need more processing power, your phone will work up to that mHz.

It stays at 245 unless I overclock it back to 600, then when I locked it it went back to 245 and kept doing the same thing.
I had to uninstall setcpu and restart my phone and its fine now

Defy + max OC ?

If defy can be OC to 1.1~1.3 GHz from 800 mhz then y can't defy plus be OC to 1.4~1.6 GHz from 1GHz ? Since defy+ has better chip set than defy though CPU n gpu used remains same ...

Hi, 1200mhz vsl60 is enough. Or you want kill the lifetime of your cpu and over this the battery drain empty before the handy is on.
Sent from my MB526 using xda premium
Defy and Defy+ have the same CPU but different kernel (which is software). The kernel limits the clock. Defy+ stock gingerbread kernel adds Clk4 and Vsel4 which are 1 GHz and 58 Vsel by default. I have a Defy+ overclocked to 1.2 GHz Vsel 60. The clock is limited by the kernel and Vsel by the hardware. My hardware at 1.2 GHz is stable at 60 Vsel, yours may be stable at 58 or 62. I know some people OC their Defy at 1.4 GHz but they set a dangerous Vsel to be stable (70 and above). 1.2 GHz is enough.

You can try it yourself. The max I've gone to is 1300 MHz/ 68 vsel... battery heat was very high at 68... many others have also tried, and get the same result as I did.
But as they say, experience is the best teacher, so you're welcome to try it out yourself, and let us know.

So u ve over clocked to 1.4 GHz o reduced to 1.3 GHz ? I really don't understand y defy+ can't be OC more whereas defy can be as it can also reach 1.2~1.3 GHz ...... buying defy would ve been better I guess .....

are you really telling me that you find a difference in 1.2 ghz and 1.4 ghz, while you're using your phone? all you're doing is encouraging battery drain and more wear and tear on your cpu..

Ofcourse there is a huge difference betwn 1.2 n 1.4 GHz.........its all about processing speed which matters for smartfone users ...... Y would there be 3 ~4k rs difference for an 800 mhz n 1GHz cell phones?

Defy and Defy+ have the SAME CPU, but Defy+ is clocked at 1.0 GHz by default.
Cost difference is also for bigger battery and better camera

[Q] CPU Clock speed

So I was trying to mess around with CPU profiles and I noticed that the low end of the CPU is clocked at 1GHz. If I lower it with Rom Toolbox, it just goes right back up after I leave the menu. the profiles won't stick, governors don't make a difference, and I'm a little confused.
Can someone shed some light on this for me?
I thought the lowest speed was 384 MHz? Install CPU Spy and check what it says.
It is 384MHz. The lower frequency change because of project butter that make the cpu run at a higher frequency when you touch the screen.

Dont you need a custom kernal in order to change the clock speeds?
sent via xda premium with nexus 7
No, we can already change it but it won't stick since it has its own frequency management.
Sent from my Nexus 4 using xda app-developers app
Is this somewhat similar to perflocker in HTC devices? It had to be disabled to change any cpu settings AT ALL with the stock kernel.

You're right. I guess it just has its own profile to set at 1GHz when the screen is on, because the CPU Spy showed it in Deep Sleep/384Mhz for the majority of the night.

Safe clock speed

Hi is 1.2ghz safe to use for a long period of time?? Not on peformance gov coz im using it with smartassv2 i assume its safe because the defy got pumped up to 1ghz from the standard 800mhz on the plus and newer models and will it serious harm to cpu???
Sent from my MB525 using xda app-developers app
i had the clock frequency at 1.2 ghz for some days and it went good, so i think that's safe
My Defy (MB525) is running at 1.3 GHz for over a year. Not a single glitch. (SetVsel config: 16 Vsel1 @ 300 MHz, 28 Vsel2 @ 600 MHz, 70 Vsel3 @ 1300 MHz - up_treshold 86 %)

Well battery consumption mostly depends on using the 3G in my case. I am connected to mobile internet all day, so battery lasts from 12 - 30 hrs. Temp is at 30 °C on stand by. While playing, e.g. Predators, it is at 42 °C.

[Q] Lowest power consumption state

I have read in some forums about the "sweet spot" of cpu frequency (The cpu frequency at which power consumption by the phone is the least possible).
I want to know what's the "sweet spot" of MB526.
Anyone?
300 mHz, because the vsel is lowest at that frequency? Not sure what exactly is meant by sweet spot

Sweet spot is the cpu frequency at which power consumption is the lowest.... Any frequency lower than that will actually increase power consumption...Apparently, for the Galaxy SL, it is 400Mhz....

Apparently not. Too low frequencies can make the phone unuseably slow + increase power consumption:cyclops:

Exactly. As vsel decreases, power consumption decreases and because 300 mHz has lowest vsel, it is the least power consuming state

OK, well...
I also don't understand this relation between low frequency and higher power consumption, but there is no real difference in battery usage between 300 and 600mHz for me at least. Just set Max Freq to 300 or 600 and use ondemand/conservative governor.
