CPU temperature?

Is anyone working on a way to monitor CPU temperature rather than battery temperature?
Matt

I don't know if anyone is working on it. I also don't know if our SoC has the necessary thermal sensor(s) to make this kind of software possible.

I'm afraid no-one is working on it, and any devs I've contacted for that didn't care at all. I was politely sent off.
The Sensation definitely has the CPU temp sensor (there is often a thermal deamon running on it), but still no devs wants to spend the little time required to make it happen.
NOTE: This requires a custom Kernel, currently available are kernels from Faux123, showp1984 or Leedroid, maybe also from MDJ.
None of them are actually working on that. One of them said that we will get CPU temp in the next kernel update, but that was already 3 updates ago!

GPU overclocking

Does anybody know what it takes to overclock the GPU in the Droid Charge? I generally think that CPU overclocking is pointless, but GPU overclock should help terrain data in Google Earth. I have lagfix installed and verified working.
I am currently on the underclocked PBJT kernel. I assume I would have to migrate to the overclocked PBJT kernel, but I don't know of a way to control GPU clock from there. Ideas?

After installing the OC PBJ kernel, download and install an app called Voltage Control.

There's a difference between the CPU and GPU. Voltage control only changes the CPU clockspeed. You would have to ask imnuts if it's possible to oc the GPU.

I found where you can change the FPS cap, but not the clock speed.

Would that do anything without a clock speed increase?

No. If you see the FPS waver, then it is not at its FPS cap, therefore it would be pointless to raise the cap.

Perhaps it's the extra ram that gives the Dinc2 its edge.

RAM makes everything better and it's the reason why certain apps seem to be quite slow(n64oid, gun brothers, etc). If those ****heads over at Samsung would've added more RAM this phone wouldn't have any problems, sure a better processor and a notification LED would have been nice but the only thing actually needed was the RAM.

The requirement for more Cowbell aside, does anybody if this is possible? The Galaxy Nexus will have the same GPU but clocked at 384 MHz vs 200 MHz on the Droid Charge.
I am curious if they have somehow reduced the process size or added extra cooling capacity, because that is huge difference.
In any case, it makes me think that GPU in the Charge could use a bump up without causing issues.

Holy dead thread batman! At any rate we can't increase GPU clockspeed because it's probably controlled at a hardware level, rather than variable by kernel.

I do believe the glitch kernel on the fascinate does include gpu overclocking. No idea if that could ever be implemented on the charge. If it could it would probably have to be an MTD based kernel like glitch that is currently for MUIU and Cyanogen roms.

All of my phone gpus have clockspeed dials on them.
And not to be even more of a smartass but the kernel is in fact the exact piece of software that interacts with the hardware so you kind of contradicted yourself.
It has been done with glitch kernel. Haven't seen any tw kernels that support it.

I meant that we don't have anything in the kernel that can adjust the clockspeed. I don't really know about any other phones since this is my first smartphone. I just say what I feel is correct. And yes, we may eventually be able to control it through an AOSP kernel, but we don't have that right now, so I don't think it's relevant information.

Chocolate Ice Cream Sandwiches?
I came from the Fascinate and the Glitch Kernel with CM7 was really rocking. If we ever get GPU overclocking it would very likely come with the same combo or a Glitch CM9 combo either of which is a long way off.

Correct me if I'm wrong, but it sounds like what we would need for this to work is a working ASOP kernel, thus we would need an official Gingerbread OTA update first (maybe not 100% necessary, but it should be easier?) in order to base the kernel on?
Even with a working ASOP kernel, I assume that it would have to be specially modded to allow GPU control.
Not that I expect CM7 or CM9, I'm pretty happy with the latest leak, but it seems that CM7 or CM9 would more or less be a requirement for this to work? I hear that MIUI is not in development for the Charge because the lack of LTE in China.
Keep in mind that the Charge is my first smartphone so I'm sort of a nube.
Big thanks to the devs who turned this phone from crap into gold!

Undervolting

Could some give me a quick rundown on undervolting a kernel. I'm using faux's 0.4.2 oc/uv cm7 kernel. From my understanding its already undervolted but I'm confused about whether I should/can adjust those settings for better results or if I should leave them alone.
Info greatly appreciated.
Sent from my LG-P999 using xda premium

Each chip is built differently, so you have to experiment on that yourself. That kernel may already be undervolted but it may not be right for you. I say adjust until you hit instability and then go from there.

Sorry to jump in on this thread as well, but could you give us some info on how you would undervolt a kernel?
I have setcpu installed, is that enough? Is it possible to break my phone?

Yes anytime you make you phone do something it didn't do from the factory there is a chance you could damage your device..its thx to all the great devs and people that test that make it easier and less likely also the more you read and understand what it is you are actually doing to the device helps alot!
If you have a kernel able to be overclocked/undervolted yes just use set CPU to adjust the settings.
All chips are different just cause a specific setting is working for someone else means it will work the same for you!
That being said I use:
Trigger 8/22 rom with faux123'a 0.4.2 kernel.
My settings:
Max-1408mhz
Min-389mhz
And have 1.1 GHz down to 389 mhz undervolted by 50 and no undervolt above 1.1
also have different profiles set for screen off and in call..
Good luck how this helps..

Thank you for such a detailed explanation! I'll be more weary of fooling around with settings. I'll probably set mine similar to yours.

Thanks everyone. I understood that setcpu would be used for the changes I was more wondering what the changes would do. Like undervolting by 50 for instance, what does that give as far as battery life? Im a moderate to heavy user and I only get roughly 8 hours off the charger before it needs to be back on, great signal all day too.
I suppose I'll just have to tinker with it till I get crashes then adjust from there.

How do u get the undervoltage adjustment? i have set cpu and when i try the voltage button on set cpu, i got forced closed. Thanks in advance.

Sounds like a bad install, try uninstalling setcpu then re-installing it or fix permissions in CWM or terminal
su
fix permissions

Used to have that issue too. Try the setcpu available here on the forums, I think that's the one the worked for me.

OC drivers anyone?

Hello all. Im currently working on an OC tweak for our beloved SGS4G; however, I need a driver made from the kernel. I have researched this a bit, but have found that is far beyond my current capabilities of building such a thing. So, I am asking if there is anyone out there that would be willing to help me with this project?

i would say bhundven since he is a kernel dev and he is experienced.. but as far as i know he is very busy at the moment.
but i guess you can give it a shot

I know he is really busy and didn't want to bother him, but it looks like he may be my only option as the other 2 peeps I know that can do this have dropped off the grid for a little while.

I'd wait for him to implement it to his kernel. It's in his list of things he'll add.

I didn't see that in his list of todo's... but that would be great because we could just use scripts to modify it...
However, i'm trying to figure out how to write a universal script for all kernels... I have a good idea on how to do it, just won't have much of a chance to work on it in the next couple of weeks...

There is a c file in the kernel with all the voltage, clockspeed, and other modifiers, that... again as I said before, I could modify but it would decrease the stability of the kernel, and that doesn't help when you're already trying to debug other problems.
The path you are on for a universal oc/uv script is what tegrek is. Except they have custom kernel modules.
Wait for oc. You will be happy.
Sent from my SGH-T959V using xda premium

tegrek is one of the major reasons you dont see a oc kernel for the sgs4g its highly customizable you dont have to worry bout the op updateing the kernel you can undervolt overclock etc... Oc kernels are great for phones where this app does not work so well.

[Q] What is a better app then Set CPU?

Set CPU doesn't seem to remember settings very well even though I save them and back them up. I've chosen ondemand profile and still the same problem with not only the settings I've input for battery, screen off, etc but the main screen is constantly different as well.
I'm using SkyIcs with update 7.4 and Faux 10u kernel.
Any help is greatly appreciated. Doesn't matter if its a paid app, but I really need something better that will change the speeds properly as I use this as my "daily driver"
Thanks again!

System Tuner always worked great for me. In fact, I used it with that same rom/kernel combo with great results.

You already should have faux clock in your apps. It works just fine. You can even undervolt.

I wasn't a big fan of antutu. Setcpu is what I've been using since the beginning.

Thanks i got it.

found that I have to use sys tuner and fauxclock both w/faux123 kernel for everything to go well ..
won't go into deepsleep unless force both cpus online at boot is enabled
running -.75mv across the board except like 450mhz and under which are all 812mv as per faux's recommendations ..
some phones can handle -100mv some only -.50mv
sorry to hear that about setCPU profiles not working was about to try it tonight.
still might ....
only because I'm amazing

That's no good to use 2 CPU apps. Just run a script and call it a day.

system tuner sets the voltages and forces both cores online (which for some reason is the only way deep sleep works)
fauxcpu maintains the 384-1100'ish because systuner doesnt keep it there apparently ..
so it's no good but does all I need done right ?
it's not bad either ... right ....
