i recently rooted my wildfire and have installed cyanogenmod 7.0.3 and wanted to double check something, ive been looking around threads and these overclocking guides and i saw that one of them said you only need a kernel with the ability to overclock if you are on stock rom, otherwise you can install setcpu straight away and overclock, could someone please just clarify this, thanks
Cm7 has overclock built in so no need for additional kernal or setcpu app
Go to Settings > Cyanogenmod settings > performance > CPU settings
It's basically setcpu built in

thanks, i gave it a go but every time i boot it always restores itself to 528, how can i set it to stick at a certain speed? thanks

There is a check box that says something like " set at boot" tick this and it will retain your settings

Also Smartass Governor is very good. Its interactive so manages CPU when required or when your handset is idle

so does this mean it wont affect battery too much as it will automatically reduce the speed and increase it when required, also what speeds would you recommend for min and max?

Yeah, as far as I know it caps min setting to 352 when idle/sleep even if you have yours min set higher than that. It then uses required CPU up to your Max depending on what processes are taking place.
Overclocking will effect battery life if you push it to far. I currently have mine set at 352/691 and it works for me giving speed and battery life.
Experiment your own tho

thanks again for all your help
I started this thread because i want to be able to use Sparksco kernel v14 but it freezes when its set to 1.0GHZ I been running v10 as my daily kernel and its bottomline on my top list of kernels. Any help will be much appreciated, im on the latest nightly CM255, i had to revert back to v10 because i need speed to check emails and surf the internet...If theres another update for the V14 in the future i hope that can be a fix or its probably my setup that prevents me from reaching any higher speeds, overall Sparksco you the man!!! By the way ICS devs yall get mad props peace...
I use sparks v14 kernel on cm nightly 255 clocked right under 1ghz using smartass governer no problem. I did a full wipe of everything, and formatted system before install of everything of course. Edit: I clocked it to 2ghz and no freezes here. Did you do a full wipe before the install of the ROM/kernel?

I'm going to have to give that a shot homie...
Kernel v14 is more geared for battery saving. I haven't updated the voltages yet because I'm not compiling gingerbread anymore, rather been working on getting a stable ICS rom build before I do more work on it. As soon as we get ICS gingerbread will be a thing of the past. Kernel v14 works good for some and v10 for others. I like v14 because of the battery I've been able to get on 122mhz min and 998mhz max. But if you up the min to the next highest setting (230mhz) you shouldn't get any lockups. Or even try 307mhz.
Edit: looks like 307mhz min is the only clock speed that allows me to overclock to 2ghz and not have any lockups. I'm also on cm nightly 255 pzguzman, and I always keep it on smartass governor.
P.S. The mods should be able to move this thread no problem without removing the comments or thread.
Sent from my PG06100 using xda premium
Yeah, forgot to mention as sparks said, at 2ghz the min is at 307mhz.

Oh okay i see Sparksco thanks for clarifying the setup, i dont mean to steer anybody in the wrong direction especially from working on a ICS BUILD which is the most highly anticipated OS for android. But im going to flash v14 and try out the setting and will get back and let you know thanx homie...
No luck but its amazing how you guys achieve the speeds... Tried the settings but my phone cant handle the pressure lol...Im gonna stick with this kernel tho... My bad for posting this thread in the wrong section its a rookie mistake...

It worked i only needed to do a full wipe, thanx homie...
By the way Sparksco i got your setup on my rom, fully functional overclocked at the max with no feezes, thanx homie...
YOU'RE USING THE WRONG GOVERNOR MIN/MAX SETTINGS
For example:
IF I want to get 2ghz out of my phone I use the performance governor and use min/max of 2ghz.
OR:
I would use:
Gov: Smartass
Min CPU: 300mhz
Max CPU: 1.5ghz
You would freeze too if you were a CPU constantly going from 100mhz to 2000mhz all the time!

Smartass2 was made for the HTC Sensation which is a dual core gsm phone much like the Evo 3D (but cdma instead). I could never get it to clock passed 1.4ghz so I don't think it likes our phones much. It's a great concept but the normal old smartass still works much better for the shift.

FWIW I am hitting 2.0Ghz with no lockups or anything. I previously had been using ScaryStable for a while and anything past 1.6Ghz would lock right up nearly immediately.

Again, it depends on the governor and the min cpu. I ran scary stable at 1.9ghz for 24 hours+ straight, no lockups.
for the heck of it I ran it @ the min of like 1something hz for the low and 2.0 max just to see how it ran, and it was solid.

I understand but say you ran scary at min 100mhz and max 1.9ghz with a gov of ondemand, that would freeze for sure on any phone.

I think what he's saying is that he ran this kernel (pershoot v14) with a low min and a high max and it ran fine.

Hi All,
Is there there a way to change manually the CPU/GPU governor without the use of external application such as SETcpu ?
Thanks

There are some files I found DEEP in the filesystem once that list the Governor, min and max, but I would definitely NOT recommend you screw with that. May I ask why you don't want to use an app? Also, why not use one of the many ROMs with that feature built into settings.apk?

Hi guys,
Thanks for the replies. What do I need it for? As usual, to see if any other cpu governor or I/O scheduler would do a better work.
SO far it it seems the defaults are the best combination

I meant, why not use a third party app?
Sent from my HTC Glacier using xda app-developers app
The only reason is that I have read somewhere in the forum that external applications such as SetCPU will simply take some additional time on reboot. Other than that no real reason to do it manually.
EDIT: one more thing, using 3rd party applications I can only see about 4 CPU governor. Thought I will be able to see/use some more via command line

Well, there are always OC Daemons. That's probably where you read that, in the original explanation regarding Virtuous OC Daemon.
Sent from my HTC Glacier using xda app-developers app
I guess Virtuous OC daemon would be valid for me if I was using that ROM.
My ROM doesn't come with any OC daemon or tweaks so I am looking for something else for it.
EDIT: To make a long story short, Using Glacier_One_V_1.3 and I can't seems to get the Smartass CPU governor for instance.

Lol. Virtuous OC daemon can be used on lots of ROMs.
There probably isn't a smartass governor built into the kernel, dude...

Governor default is predetermined by the kernel if your question hasn't already been answer
Sent from my MyTouch 4G using xda app-developers app
Hi Guys,
Been researching the thing and you're all correct.
Kernel predetermined.
Checked the files and it seems this Kernel (V3) doesn't support the additional modes.

Hi,
does anyone have working CPU underclocking/undervolting/core-shutting in CM Nightlies? The Performance setting there is broken and set limits only for fist core.
I mean the battery life is not bad, but I would sometimes appreciated ability to go into somehow ECO mode (for example runnning only on one core) when I'm nowhere near charger with nearly dying battery.
TY

Nope, not until someone creates a custom 4.2.2 kernel. Maybe Faux (or others) are waiting for the CM10.1 kernel rebase to be released as this will be a much better one to start modifying?

All of the 4.2.2 roms I have tried have a settings option called Performance that lets you set the min/max CPU speeds, switch between different kinds of governors, and play around with RAM management settings.

So far the clocks have stuck Meaning once you set a clock its stays there, doesn't reset to default. As for govs and I/O, I use msm-dvcs as my gov and row as my I/O. Msm-dvcs will shut a CPU core down when not needed

Unfortunately I don't dabbled in profiles as I personally find them unreliable. I just stick it at a certain clock and set my govs and I/O. If you want to know my configuration, I set my clock to 1350MHz and min to 384. The gov and I/O I've already mentioned.

thanks bro, that's really informative, i think ill solve that out but once again, battery life with speed is what everyone's after, yes the M has plenty of oomph under the bonnet but clocking it down will save battery yeah?
the profiles you have set are stable enough? no random reboots or lags?
