If I Undervolt the CPU by lets say 100mv or more (I don't oc past 1.4 ghz as it give the most frames in games) will the GPU get more juice ? Cause if ocing to 1.6 the gpu works bad and on 1.4 works better (5-10fps more) . So is this simple. If UV the CPU the GPU will have more mvs ?

I've Tried a lot of rom, kernel, too much time spent on this phone to see that ondemand governor, interactive or conservative doesn't stop frequencies of Tegra 3, I see through CPU Spy that, even I stop max clock to X mhz, it goes 1.4 ghz, 1.5 ghz...
There is a kernel that work? A rom that work without this problem? This is a bad culprit for the poor battery of this phone...
I'm running KT747 (Build 3/14/13) and I'm just wondering what this stuff is and does it affect my battery/performance, and if so how? Thanks to anyone that can help!
Overclocking speeds up main processor past 1.5ghz, kernal must support this function. Underclocking slows processor speed to whatever you set maximum under 1.5ghz. Under is good for saving battery, but can cause lag depending on how you use your phone. Governors control how the processor handles requests, such as opening an app, with on demand gov, processor ramps up quickly, with lagfree gov, processor kinda takes it time, which in return saves battery. If your not comfortable or understand this totally, be careful, search for guides on xda about overclocking and governors. Overclocking can cause bootloops, freezes, or other issues. I overclocked mine to 1.7ghz with no problem, but I'm running Agat kernal.

I am using ElementalX kernel on stock 4.4.4 android. I have to OC set to 1.944GHz currently. AnTuTu bench at 1.944GHz and 450MHz GPU gives me between 24-25k result. Now if I lower the CPU to 1.89GHz it drops to 21k. And if I go back to stock freq I get 19k. Something does not seem right in the test results as related to the frequencies. Question is this: Are there sweet spots in the frequency range for the CPU?
P.S. I know many people dislike benchmarks...I'm using it for comparative purposes...

It states it in the thread, having cpu at 1.9ghz is not economical with battery consumption and performance, it Is best at 1.7ghz

You should monitor your CPU temp and frequency while benching.
You would see that your CPU's temp probably goes above 70°C if not higher and so the kernel thermal throttling policies would downclock your CPU's max freq. in order to keep your CPU "cool".
If you first bench @ 1944MHz then bench @ a litle lower frequency and have very lower score then its not because of the lower freq. but because you did first heat up your CPU @ 1944 and when you re-run @ lower freq. your CPU is already very hot and so does a severe thermal throttling.
Last point : running your CPU @ 1944MHz is not good since thermal throttling while happen every now and then.
Not convinced?
Then simply launch the camera app and try to take a video of 5 mins...your CPU will become so hot that it will downclock to something ridiculously low and your recording will become jerky.
Is it safe to overclock the processor and GPU a bit? Asking this since this tablet's processor is simply an underclocked Snapdragon 600.
(If I do, I'll be using ElementalX)
I don't think it makes that much sense. The s4 pro is already fast and does everything (and I mean everything) 600s and 800s can (obviously not considering chipset-specific tasks that our devices are not capable of in any case). I own a n4, same exact SoC and clock speed, and overclocking can be done up to 1.75 GHz. Even if I were to overclock I'd avoid the GPU. In any case follow the instructions provided by your kernel dev, he surely knows best
When you install ElementalX, the installer will guide you.
I'd recommmend you to overclock the cpu to 1.7 GHz and the gpu to 450 MHz. With everything else, just stick to the default.

I overclocked to 1.7 GHz and the GPU up to 491 MHz, but the performance improvement wasn't even notable and I got only 800 more points on AnTuTu and 3 or 4 more FPS on 3DMark
Hey guys!
I installed CPU Spy and Performance Tuner and noticed that my max CPU speed is 1440Mhz but as far as I know it should say 1800Mhz. I know we have 4 cores running at 1.4Ghz and 2 cores running at 1.8Ghz which is the speed advertised.
What is your max CPU speed for your G4?

CpuSpy doesn't know that cores beyond 0-3 exist, so it only shows the first quadcore cluster. App hasn't been taught bigLITTLE yet it seems.
Oh I see, I thought I had like a bad CPU since I couldnt find something about it. Thanks!
Same here I only get to do 1.44
Use Kernel Adiutor App. it's compatible and detects all cores.
