[Q] Changing kernel supported CPU frequencies - Android Software/Hacking General [Developers Only]

I've an ARM processor which is capable of going upto 600Mhz. But the recent 1.6 to 2.1 update from the manufacturer changed the got the frequency down-scaled at 480Mhz.
I've rooted my Android phone, and now even if I try to set the maximum frequency anything beyond 480MHz using SetCPU using the slider, the "current max frequency" shown in green-color, refuses to go beyond 480MHz.
I'm not sure, but I'm guessing that the current kernel which came with the update doesn't allow frequency to go beyond 480Mhz.
So, can anyone help me, with how to change the frequency back to 600Mhz?

No one can help!!
Atleast can anyone help me identifying the current ROM for my phone?
And since this is an uncommon phone, I would like to know, how to determine which ROMs I can I try on this device?

Perhaps you should provide some useful information. You haven't even identified the phone in question and you expect people to tell you what ROMs/kernels you can run.

I bet it's the Optimus Boston a.k.a. Gigabyte GSmart G1305 "Codfish".

[Q] overclocking with Set CPU

So I rooted my Droid X2 and installed Set CPU. I had problems running set CPU, I couldn't use the drop down menu for setting CPU governors, I also couldn't over clock my CPU, just under clock. Does set CPU work with the nvidia tegra 2 dual core processor in the X2? If not, which app will let me overclock and change CPU governors?
You have to have a custom kernel that allows overclocking.

I'm really new to Android, i've been using iOS for years, and finally jumped the fence. I just rooted my Droid X2, used Titanium Backup Pro to freeze all the bloated apps, and I wanted to get more control of my CPU, as well as overclock a little. I thought I could just install SetCPU and I would be able to Overclock.
So in order to have a custom kernel I would have to install a custom ROM? Such as Cyanogenmod? As I said, I am pretty new to Android, but if I am correct, Cyanogenmod is not available yet for the Droid X2 is it? Are there any other custom ROMs that are available or would work with my X2?
Is it really even all that necessary to overclock what is already a pretty powerful device? Nvidia Tegra 2 dual-core processor is powerful in its stock form isn't it? I would almost think I would gain more by dialing the CPU down at certain times, at least I would gain battery life. I think I am able to set up profiles with SetCPU without having a custom kernel, right?
This is a useless app made by Vietnamese people (I'm Vietnamese). It cannot overclock which many people mistakenly believe, and it only has the task of limiting the CPU speed, the CPU speed is managed by the OS and limiting it is a bad way because no matter what task it does it will be slowed down. When idle the CPU will automatically reduce its voltage and speed by OS. Any process no matter how big or small with high CPU speed it will be processed very fast even with small tasks that are reported not to use up CPU but it will still be faster than a slower CPU. Kernel Auditor is also useless.
it's not you install a custom kernel to manage cpu to overclock by some app but you're going to overclock into kernel using a custom kernel

Activating second core

As I heard, ICS does not support the second core. Does anybody ha an advice how to activate? Running ICS with a single core doesn't make fun
Where did you hear this? Dual-core support was added in Honeycomb and is present in ICS.

Post 160....I'm not that familiar with Android like I'm with WM, that's why I'm asking such noob questions. All I want is to get my Xe running
Um, I don't know where you've been but ics is where multi core is FULLY supported and implemented.
While it "seems" core 2 isn't being used/activated, that's because our CPU architecture is asynchronous smp (meaning cpu0 = always on, while cpu1 = on when cu0 reaches a certain load threshold).
The CPU is not meant to have both cores on at the same time for extended time periods. (And even though many claim that on the rough ics leak, forcing cpu1 online increases phone's speed, they're experiencing a placebo effect)
Also, those people in that tthread have no clue what they're talking about when it comes to our CPU.
Ics cannot and will not change our could architecture! People are just using wrong ideas and terminology and wrong reasoning. Our phone is asynchronous smp, and when people read that gb didn't support multi core truly, they though it meant ics would always have both cores online/activated, but that would be changing the CPU architecture to synchronous smp, which you cannot change.
Tl;Dr: they are wrong, ics supports multi fire truely, our phone will still turn off second core when the cpu0 load threshold isn't met (load of cpu0, not speed of cpu0).

the solution is in that post allready,,
system tuner pro and force CPU1 online
ok, thank you both.......I was just looking at the system tuner screen which said that core II is off when gov is set on batt saving......will test the ICS for a while and will decice then if I go back to the old one.
I appreciate your help!!!
Ive found that using system tuner to force all cpus online with ICS makes for a LAGGY experience. Crappy benchmarks as well.

Well, it showed me that one core is offline....

That is normal. That's how asynchronous smp works.
Cpu0 = always online, cpu1= online when cpu0 meets a load threshold, then goes back to offline when the load on cpu0 drops below the threshold.

Here is a test that doubters can perform to prove the 2nd core activates when needed:
Run a benchmark like CF Bench that really puts the processor to the test. While running, open up system tuner and watch the other core. You will see it come on and off alot. For me, it just stayed on while I ran CF Bench. When the benchmark was over, the core turned off. Perfecto!

[q] cpu chipset

does anyone know if setting the CPU SPEED to 1.5 GHz is dangerous while the SENSATION XL has the same chipset as the desire s has (Qualcomm Snapdragon MS8255) and the SENSATION XL's CPU speed is set to 1.5GHz .
sensation has msm8260 (dual core 1.2-1.5 GHz and adreno 220)
Sensation XL indeed has MSM8255.
Just like in PCs, chipsets in phones are binned not only by their type, but also by their target frequency. You don't go overclocking Core2Duo 1.8 GHz to 2.4 GHz because it's "the same CPU", right? Because it isn't the same CPU. The same applies here.
אז זה מסוכן או לא ?
English, please.
Answer - would you run the CPU on your computer at 1.5x the speed it was made to run, because there's CPU with the same name (i3/i5/i7/whatever) that runs at 1.5x the speed?
The same answer applies to your phone.
I expect people to be able to make minimal logic work with their own brains rather than just answering "yes/no". I think that this way people actually understand more than what they've asked for.
i guessed that was the answer but just wanted to be sure...
thanks anyway !
msm8255 should run stable on 1.5GHz (if stock freq is lower)

No it won't. It depends on the specific part, and few parts run stock 1.5 GHz without stability issues surfacing / burning out very fast (if overvolted).
If you really want - you can try it on T-Mobile G2, that has MSM8255 of the earliest bin, with stock at 800MHz. Good luck, don't forget to write how did you like a phone as a toaster.
I suggest refraining from bad advice, especially when it's in the forum and it's not your phone you're talking about. You can burn your phones as much as you like, but don't go around suggesting it to others. Just let me understand something: you have stock non-rooted ICS and have no idea about such basics as which guide to use to downgrade, but you allow yourself posting about chipset frequencies?
so which speed can i overclock to that shouldn't turn my device into a toaster ?

1.2 runs most things with no lag.
Sometimes you're the windshield; sometimes you're the bug.

The point is each chip is different even if the same model
What works for me on my device won't necessarily work for you
So test and see if your brave enough, but be aware of the consequences

I overclock my ds to1.5 every time I play games and it doesn't even get warm. So I think it's pretty harmless.

Moto Z clocked @2.15? Naahh... @1.82? Naahh... it's @1.59!!!

Nobody still have discussed it but... our Moto Z XT1650-03 are *really* underclocked!!!
Let's start from the beginning...
First models on marked were the Verizon's Droid version and their SD820 were clocked @2.15 GHz (at least so declared officially Motorola)...
Then came out the unbranded international version and, even if not so "advertized" by Motorola, it's clock was lowered (officially...), to 1.82 GHz. True?
False.
Even if apps like CPU-Z find the CPU able to work between 300 MHz and 1.82 GHz, the real clock frequencies used by Moto Z are in the range 652 MHz - 1.59 GHz!!!
Using root, both my "reference" apps, Antutu CPU Master Pro & FauxClock show this range (652 - 1,59) as used BUT while the lower clock can be lowered to 300 MHz (best setting for longer battery life in my opinion... ), there is NO option to go over 1.59 GHZ at all!!!
From my experience there should be two more setting 1.82 GHZ and, probably, something around @1.7x GHz, but both are unavailable on stock kernel.
So, if @erfanoabdi has really raised clock to real 2.15 GHz in its modified kernel, the difference in performance should be really noticeable! (I don't know about battery life anyway... ).

Hi, let me explain it
If you take look at snapdragon 820 details and tech specs you will see this processor have 4 core and
2 core of them is clockable up to 2.15
And other 2 core is clockable up to 1.5
And you can also check it by kernel adiutor app on your device.
International version of moto z using same hardware as Verizon edition but kernel of them are different and CPU of it underclocked to 1.3 and 1.8 Hz
There is some restrictions for GPU too and I fixed them on my kernel
So don't worry
Use my turboZ or Verizon (http://forum.xda-developers.com/showpost.php?p=69459891&postcount=205) kernel for better speed and performance

With turboz kernel 0.7 it never pass 1.59.
Performance are great all most everywhere with elementalX governor. Just some scrolling stuttering. All is fast and no lags.
It's probably because it's reading the speeds of the other 2 cores in the "efficiency" cluster.

So any battery saving experience when you lower the minimum CPU speed to 300MHz?
Is it really running at 300MHz instead of 652MHz?

Hello. I am interested in purchasing this phone but am confused by the different versions and conflicting specs that I see online for each. So certain versions have the faster 2.15GHz processor vs 1.8GHz but lack Band 12 support (I'm on T-Mobile). While the others have Band 12 but have the slower processor? Is that correct; there is no way to have both?

You can have both by unlocking the bootloader and installing custom roms.

So I could purchase either version and use a custom rom to unlock the missing features, i.e. the hardware is identical? Is one route recommended over the other?

I think only a specific variant like the Verizon one is in a bs state when it comes to software. Other than that one, you should be "on equal grounds".
