Can someone explain clock speed in CM 5.07?

Can anyone provide some info on how the CPU clock speed is configured in CM 5.07?
I currently have a MT3G and it's my understanding the CPU is designed for a max speed of 528mhz. Does the CPU always run at 528mhz or does it throttle up to 528 when needed and throttle back down when idle? Is there a max and min cpu speed in the latest CM build? I know I can use apps such as Overclock and SetCPU to adjust the throttling of the CPU and to overclock beyond 528mhz, I'm just wondering how it works by default in CM 5.07 before I decide to mess around with overclocking.
Thanks!

You need to get Set Cpu then if you pm me I can give you a link for zip you flash in after you have set cpu installed...it's universal and will let you clock your speed up around 800, though I recommend something around 614...

Oh and by universal I mean it will work on any rom, for the 1.2...maybe it will work with any other phone but Ive only tested it on my-touches running different roms, therefore different kernels. Correct me if I'm wrong...And I didn't make it so I can't take the credit, I happen to find it but forget the site...

how's the impact on battery life?

7-10 hours max depending on phone usage...

What is the processor temp safe range?

(Title)
I ask because I used SetCPU to overclock in CM7 to 787 (806 locks my phone up), and I want to be sure the temp stays okay.

i'm not sure about an actual temperature range, but i would say anything that doesn't burn your hand when you hold it is acceptable. what build of cm7 are you using? i've been running set cpu set at 806 with nightly builds from a week ago up to today (13-19) with no issues.

Running build 18. 806 has always locked my phone up, even on CM6

But afaik, the temp the phone gives you is the battery temp, not the cpu temp, so it could be much higher than the reported number...
Anyway, 42° is moreless the line temp for me.

Huh. Didn't know that. Thanks for the info.
My battery got to around 46C while charging.

Well, if it's just charging you can create a setcpu profile that it lowers the mhz when doing so, so it doesnt heat up too much. At any rate, supposedly every good device should work fine under 50°C, if it's charging without overclock and you still get 46° then it should be safe.

If you can't measure it, you can't manage it. Try loading the "Perfect System Monitor" app from the Market. It will give you CPU temp data. I wouldn't worry about anything under ~50* C.

Try installing an overstock kernel, like Eugene373's Deadhorse Kernel, then you can download One Click Lag Fix from the market.

Just install a kernel that has oc capabilities and use set CPU to adjust the frequencies

after you have the oc kernel installed go into set cpu and set an audible alarm and for when your temp goes above 115 Fahrenheit, in that profile have it drop your clock speed down to 1000 or 800 to help your phone cool off before reactivating the full oc. Ive never had any problems with the cpu getting to hot oc'd to 1.2 thats not to say you wont.
Cheers

I don't think that overclocking and not destroying can be done at the same time.

Flash it, set clock speed with setcpu or voltage control, cross your fingers and hope for the best.

All you need is a kernel that supports OC ie. (DoW, Tigersblood, Overstock, Dragon) you should be golden but double check compatibility with whatever ROM ur running.
I use "set cpu" to torque it up to 1.2(or whatever the kernel OC's to) Then i use "SystemPanel Lite" to check and make sure its actually OCing. In the system app it has a CPU Clock in the top right corner which monitors ur current cpu. When the system app opens it has a list of active applications i simply move the list up and down repeatedly really fast and watch the "CPU Clock" if it maxes out at 1.2 or whatever its good to go. I remember one time(cant remember what kernel)but set cpu showed 1.2 or 1.4 and even in system CPU info it showed OCed but if you did like i just described the CPU Clock never went above 1000Mhz. Like it was just showing as OC even tho it really wasn't it was really weird the clock would max out at 1000Mhz with dead space above it like it could go over but never would.

i never knew you could set audible alarms(guess i never really looked into it) thanks for that! running DoW221 OC to 1.4 i used to see my temps hit 120-130 it would freak me out! but never had any problems except for batt life avg 6-7hrs.
Personally my best OC ROM/kernel setup to this date has been MALICE[EDT]+Tigersblood(any release) everything works and great batt life for a OC kernel

Just make sure you backup before trying. Some Vibrants cannot handle overclocking (and there's no real way to know until you try). Mine is one of those, and if it can't handle it, an Odin to stock will be in your immediate future.

[Q] Unable to underclock below 245mhz with cyanogenmod 7.1.0 rc1. unbelieveable!

Yeah. Even when disabling the perflock, it won't let me chance the minimum frequency. ive tried setcpu, cpumaster, cputuner and a bunch of other apps. is there anybody here who's had the same problemo?
my kernel is 2.6.32
before rc1, just two hours ago, i had nightly version 173. i flashed rc1, because obviously i misread that it had a different kernel, 2.6.35. yeah right. im gonna rage soon. the battery drainage is horrible.
plz helps!??!?1one
edit: oh, what would you recon as the best rom for legend? thanks!

Maybe overclock is only on stable version, rc and nightly made for testing other stuff.
I use some mod of blayo rom, no overclock. Works awesome. More then 90 days without flashing or even reboot. Well only feature i need from custom rom is root and wake up on trackboll.

Thanks for replying! actually, the in-built cpumanager works like a charm, and i have been using it clocked to 825mhz. And cyanogen all in all works great, suprisingly nightly version 173 works better than 7.1.0 rc1.
But still, i cant UNDERclock the dang cpu. someone had his legend run with minimum freq at 19 mhz - and had a large impact on the battery life with the setup.

And it worked ok with incoming call?

There is no way to clock this kernel below 245 MHz unless you alter its frequency table and recompile it yourself. May I ask you why do you want to go below 245 MHz?

Bummer. Got no skills for that. I do alot of reading, and the system does not need 245mhz to run a screen with some text on it, i suppose. oh well...
so, your rom can be clocked below 245mhz? would you recommend it for everyday use? thanks!

Yeah, but when you are reading, you have to slide a lot I guess?
My conclusion was (after an extensive testing) that lowering the speed below 245 MHz didn't add much to battery life so I'm actually using just two profiles... one for screen on 245 - 768 MHz and one for screen off 122 - 480 MHz. Scaling governor is interactive in both cases.
If I can recommend my ROM? Dunno. I'm using it since I started it and I'm satisfied with it. I don't need anything else

SetCPU Recommended Settings

Just a thread to see what people are setting their CPU speeds/governors at.
When I first opened the app stock seems to be
Min: 1026
Max: 1512
Gov: On Demand
All I have done so far is lower min to 594 because I felt 1026 is too high.
GS3 T-Mobile R00T3D

I set my min to 486. I also set up a screen off profile for 384-594. Gonna see what kind of battery life I get.

Setcpu is messed up, try using moguls to check default values, and make sure you clears all data on setcpu before if you're gonna try to.

The default kernel won't let you change the min. You can try, but it goes back.
We need a new kernel to lower the minimum freq

I am using No-Frills CPU Control and it is keeping the minimum freq change ( unless the app isn't able to read the CPU freq correctly).

Nope, it says requested frequencies or something like that where you changed it, but the actual ones are on the left, and they are still the default.
We need a modded kernel. Anyone know of someone that can do that?

How do you know they are not chging in No Frills if it says it is?? If you reboot and it sticks, it's working.

On the left it is saying my min and max freq is 1.5ghz, so I don't think that is right. When I check the report of the last 5 seconds it says its on 486mhz 90% of the time (486 is my set min freq).
Edit: Actually on the left it now says min is 486 and max is 1500, so hopefully it is working correctly.

Mine seems to be working with setcpu also

If the app is to be believed my settings are holding as well.

Tablet cpu monitor is what I use. It puts the frequency in the notification bar. Maybe that will clear things up for you guys..

Guess I could be wrong, did you reboot to get it to stick? I could not get mine to stay.
Also, curious what the voltage is at the lower frequencies. I wonder if they are the same the lower you go and therefore samsung didn't lower it past 1026.
Can anyone see what the default voltages are set to?

What version on SetCpu are you using?? I think you need to be atleast in the 3X versions to get it to work right.

I can't seem to set the Max to 1.5ghz it only set the max to 1.0ghz. I think SetCPU still not supporting the S4.

Just used SetCPU to set max to 1512 and min to 384, with different profiles, restarted...and it seems to stick.

yup! the slider sticks but look at the print just above the slider; mine still says 1024 even though the slider is at 1512 max. I don't think setcpu supports snapdragon S4 yet.

Not sure what's wrong with yours. I've had mine set at 486 - 1512 since I rooted. I've rebooted several times and it stays at my settings. Yes, even the print above the settings.
