I have been looking at jelly bean trinity kernels and I have noticed that they come in different GPU speeds. I was wondering if the GPU stays at 100% the whole time or does it underclock its self when not in heavy use?

The gpu scales too, just like the CPU, albeit at different frequencies, if my memory serves me right (it never does) its like 143, 266 and 384 MHz. Something like that anyway.

Yeah, I believe it uses steps like the CPU for when its not using heavily graphics or calculations.
I think the actual process is a bit more complicated because (if I recall right), the CPU and GPU are integrated.

Just wondering what the max "safe" processor speed would be? I had mine at 1.8 just to run a benchmark and set it back to stock until I can find this out. Thanks!

I have mine at 1.5 and I've had no problems.

Believe it or not, I'm running 2 ghz perfectly stable. I wouldn't recommend this as it would suck your battery dry. 1.2 is good enough.
Sent from my Incredible 2
I was able to benchmark without error at 2ghz, but developed stability issues after some time. 1.8ghz also exhibited similar behavior. I think 1.6ghz is probably the safest max. I'm only going as high as 1.5ghz.
If nothing else, I worry about the impact of high frequencies on my cpu. I run at 1.4 just to be safe

Both are pretty good but i wanna know which have the better battery life ?

Interactive works best for me. Both those you mentioned have given me lag at different parts. On demand IMO is better for battery.
zippity doo da.
Based on personal experience, conservative will offer better battery life as it is more restrictive about how much power the processor uses. It can get a little annoying as sometimes it will cause the phone to lag/not perform at 100%. Ondemand is more commonly used because it usually offers the best mixture of battery life and performance. The name is self explanatory as it puts out more when u need it. Like I said, I am no expert,I'm just basing this off of personal experience

conservative gives me best battery life
Conservative will.
i think the new Wheatly governor by Ezekeel on his GLaDOS kernel smashes both ondemand and conservative ... IMO
Conservative has better battery life.On demand = better performance

That's what is is supposed to do. It runs at max frequency and uses different power states. You just have to read the main post in his thread.

Omg this governor is AWESOME. Lost 3% in 24 min

I love google freaks. For general use. ondemand is better than conservative. The delays between higher frequency leads to longer active state time and therefore bigger power drain.
Conservative is good for high power cpus and in situation with long cycles in particular software.
Interactive.

Why do people have different opinions on something that should be clear?
I'm confused now
Sent from my Galaxy Nexus using xda premium
ondemand has better race to idle (at least if I understand correctly) than conservative, so it actually ends up saving more
on the other hand, conservative can be better if constantly performing low-powered task (e.g. listening to music)
wheatley combines both depending on the situation
I have a sprint gnex and I never notice the benefits of overclocking it, its the same if on stock speeds or overclocked and the battery is also the same so what's the benefit?

You usually won't notice a performance increase until you play games
Plus there are performance bottlenecks besides CPU... any of those can come into play.
But as was said... memory and graphics heavy games are where you will notice differences.
Do any of you know what a scheduler is when you go to the CPU settings? I never know which one to pick

Alright let me tell u something.
Clock it down and tell me how slow it is.
So yes over clocking does make a difference. Especially on interactive.

The scheduler controls read/write requests to the flash memory (or HHD in PC)
What options you have available for scheduler depends on the ROM/kernel.
Most should have Noop, and it is a good choice, just stick with it.
I've had a strangely smooth and good experience on Franco's kernel on cm9 with the conservative governor on the stock frequencies. Scrolling seems less jittery and the battery is excellent. It must priorities the threads differently than other governors.
I am on 196 512 gpu. Easily getting over 4 hours screen on time close to 5 on my vzw nexus.

Franco kernel on CM9
I was trying Franco kernel on CM9, but I noticed that System settings would FC when I went into Storage. Thought maybe they aren't compatible. If you've been using that combo for a while with no other problems, maybe I'll give it another shot. Are you pretty confident with it?

Hi there. I rooted my nexus 7 last night and flashed the cm10.1 rom with faux 123 kernel and been able to oc it to 1.7.
Why can't we have kernels that oc and uv efficiently like other phones and tablets?
And finally the at&t has an s-off why can't we?
Sent from my HTC One X using xda app-developers app
Because the battery will melt.
No s off because we have tegra chipset, at&t has an qualcomm chipset which is easier to crack.

What fo you mean the battery will melt? Othervdevices can handle this.

If you want that your battery runs out after an hour of use, go ahead and OC

The nexus 7is a larger device and has much better heat dissipation Than the one x.
By overclocking all you really accomplish is heating the device to thermal throttling levels quicker.
Meaning
1.5ghz for 10mins before throttle then 1.2ghz throttled
Or
1.7ghz for 3mins before throttle then 1.2ghz throttled
In this scenario by overclocking you gain an extra 200mhz for 3mins but because of the overclocking the device heats up and throttled earlier. Thus losing 300MHz vs stock for the next 7mins.
Because of the poor thermal dissipation it makes overclocking pointless

On stock 4 cores will run @ 1.2 ghz, so when you oc by 200 mhz you run 4 cores at 1.4 ghz
Though they did get an overclock that runs 4 cores at 1.5.
The cpu thermal throttle kicks in at 85c and will shut down the phone at 90c.
Battery classes as "over heating" when it hits 48c.

That was just an example.
Actually it runs single at 1.5 and quad at 1.4 stock

What about UnderVolt ???
Is there any modules to undervolt ??? Or any other modules ???
I'm from LG Optimus 4X forum (Tegra 3) it has the same CPU & GPU so they should work .
I'm sorry if I posted in wrong place .
Thanks .

Most custom kernels (NCX, XM, etc.) let you UV.
Take a look at their git, it should have the modules you need.
