It's more based on how the rom works, and the kernel yes helps with CPU and GPU scores but I noticed his GPU scores are lower than mine, one of the nation reasons I'm still stock. Because it's probably persues kernel and has issues with FPS in real world and quadrant performance.
He probably ran it 1600/1600 on performance or something on those lines
Edit: this is mine stock rooted GPU much better than his, until persues can match this without overclocking the GPU just to get the same performance I do on stock I'm not switching.

Maybe you should consider that you're not the brightest, most experienced person in this thread before talking smack.
Exposing a component to more heat means you are shortening its life, there is no doubt about that. Those with overclocked desktop CPUs often have elaborate setups with overclocking in mind. You can't add a better heatsink, or a fan to your phone. Mobile CPUs, especially, are designed to be efficient at a certain range of clock frequencies. Moving it too far from the norm means you eventually see diminishing returns.
I've fried everything from my first Commodore 64 to my current box, and everything in between. If you think the phone can function at that level for an extended period of time without failure, best of luck to you.

Dude it was part of the whole meaning of rooting and tweaking. Checking different settings for a little bit, testing them and then reverting back to defaults. I will never leave overclocked/ undervolted or vice-versa settings for a whole day... its just part of the fun of tweaking and experimenting with our devices...
Sent from my GT-N7100 using xda app-developers app

I am all for overclocking, modding, tweaking, hacking, etc. Breaking **** is the best way to learn. But that doesn't mean you should push your hardware past the point of exponentially diminishing returns, and increased risk of burning your chips out. That is, unless, you have no problem with the very real possibility that you'll need to buy a new phone.
That being said, kudos on "going plaid" with your Quadrant score

Kernel inquiry

Ive been working(slowly due to work) on a kernel for the lgog. I've been able to do some pretty heavy overclocking but I need some community preference.
Overclocking obviously causes more heat and reduced battery life. Higher overclocks require overvolting beyond required to maintain 1.5ghz set by Qualcomm/lg. Keep this in mind before asking for 2.0+ overclocks in daily kernels.
What top clock are you guys wanting for a performance kernel? Also are you guys interested in a reduced clocks kernel. 1.0-1.2 top clock with a lowered low end clock along with lower GPU and system clocks.
Personally I Dont see a big need in heavy overclocking on a quad core. However I would like some opinions before I release test kernels. I will attempt to see just how far the lgog can go at least once, but that will take around 10-20 test kernels to find the top speed.

The highest overclock that I would like to see is around 1.7-1.8Ghz even though I don't know what I would need my phone running that fast for. Now the under clocked kernel sounds very interesting .

Just looking at how this governor uses CPU, it hardly uses the middle ranges. Maybe some better governors? Just another thought.
Sent from my LG-LS970 using xda premium

I would be interested in a kernel with A 1.8 top speed slightly lower bottom end and different governors. While 1.5 is fast 1.8 with a better governor along with a 128 minimum speed would be a good comprise kernel

I don't know of anyone having speed issues to warrant an over clocking kernel, seems more for bragging rights.
I think most people would want a kernel that saves battery but doesn't compromise on speed. Also, have you looked into the wake lock issue yet?

I'll probably use faux's volt control. This is my first Qualcomm kernel so I've been mainly running through it. The n4 is far far far cleaner. Our source is a jumbled mess to an extent.
Also the other devs have found a way to run n4 stock ROM with kernel. However finding the best way for everyone to benefit is being sought after.

Hot and rooted

Title says it all. If I root my S3, it heats up to uncomfortable temperatures. If it's on stock, it runs nice and cool. Battery doesn't seem to be affected by this new heat. And I've tried a lot of kernels and ROMs. Why does my S3 get hot when it's rooted? And I'm not talking like gaming, I'm talking about basic use.

My friends S3 used to get really hot and he wasn't rooted. I turned off his location service and no more heat. I presume the heat is coming from something that's running in the background. What rooting method are you using? Also you said you've tried ROMs and kernels. Is the heat coming from rooted stock or only when you switch to another ROM and/or kernel?

that's what it's supposed to do. part of the "project butter" tweaks for jelly bean included this type of CPU jump when performing a task. that instant jolt to the maximum device GHz helps make doing everything on the phone more fluid/fast.
to get better battery on your device and troubleshoot whether this feature is hurting you specifically more than helping, feel free to adjust your max speed. start low, at say 1GHz, then bump it up a hundred at a time to find out where your phone is the most comfortable.

Can we maybe explain it as having a device that just run's hot ? It was my first inclination.
OP, maybe I glanced over it at first but you stated you have used many rom's and kernels and got the exact same response on all the ones you used ?
Did you you try going back to stock rooted and seeing how it was from there ? A completely clean slate might be your best idea. The only way a device will get hot is is more power is being used to keep the processor at higher temperatures. There really isn't any other way or than faulty hardware issue.

its not a price tag. its a script set to take advantage and make the most of the hardware on your phone. as soon as the task has begun, the CPU speed drops immediately.

I almost always use ondemand governor. In my humble opinion nearly all the other ones are inefficient or just placebo's. My phone runs streaming radio 4-5 hours a days on LTE and it never gets hot. Stays at around 918mhz at the highest. There a few bugs in 4.1.1 like the media server scanning where it will constantly scan your media because of a bad file.
Odin stock rooted 4.1.1 and then see how it goes. Factory reset it and erase /data or move to to pc or ex sd card. Won't take long and if it still does it I can't see what it would be.

What are the safest/recommended levels to undervolt in trickster mod and should each MPU level be tweaked individually OR is it OK/better to adjust all MPU levels by a certain degree?

try flashing one of the kernels (4.3/4.4 franco ) and they have all that taken care of.

There are no downsides. In fact it extends the life span of your cpu. Only undervolting too much will cause instability. So just check. Maybe do some sort of torture test..
