Hi guys I have two questions for you:
My Nexus7 has the latest AOKP ROM with motley kernel 484 GPU overclock and CPU overclock at 1.4 ghz set ondemand but my tablet gets warm a lot, it becomes hot with no heavy opened app or games, just with chrome browser or Facebook app.. what can I do? Change ROM, kernel or setting?
Then: which CPU governor give me the best compromise for performance and battery duration?
(Sorry but my English teacher is so bad)
Up
Mine gets warm at the middle/bottom left. I guess its normal, but i don't remember it getting warm on my other nexus 7 that had screen lift.

as the title says, i have major overheating issues i will use the phone for 5 min then its becomes VERY HOT so i have to turn it off i have a OC but it never gave these issues before, on any rom even disabling the oc i still have these issues.
my settings:
1300mhz(high)
200mhz(low)
noop
performance
no UV(maybe i should at one need you help)
voodoo color boost
403mb ram
didle enabled
devil idle(automatic)
BLX to 90%
no live oc
so what is the prob? im on wifi it gets hot even on half brightness
on 3g i cant use my phone for more than 5 min before i need to turn the screen of.
this is worrying me alot.
OMG u set cpu governor to performance @ 1.3 GHz do u want to Melt ur phone dude :laugh::laugh:

Governor Performance is definetly NOT for everyday use - with performance your CPU is running at max speed all the time. I think your device is broken. My SGS with 112% live oc and lulzactive is only a little bit warm after 2 hours of YT and internet.

I'm not sure if his phone is broken. My phone used to get very warm, then after I changed rom it didn't get warm at all.
Not sure why but ever since I flashed release 7 of the faux kernel my phone just seemed to get really warm, now I don't know if i just never noticed it but I'm running Motley kernel now and my phone just gets warm at the top when installing apps. I'm not sure if I never noticed it and I'm starting too or if I have a problem, HELP? Thanks.
That's completely normal. When installing asps the CPU is being used. Also, the CPU governor being used and uv'ing affect the temperature. Also, the CPU is located at the top I'm guessing.

Hey, I'm wondering too ! Since i flashed the latest faux kernel (release 007m) , my phone seems to be warmer than usual. According to the system tuner widget the phone runs around 45°C after a few minutes of use and sometimes reaches almost 60°C while i do nothing special on my phone (a little browsing, sms). Despite the fact that I've downclocked the cpu to 1.35ghz, put the governor on intellidemand, disable mpdecision, UV 75 mV and running at the stock gpu clock. I don't know if this is normal but this seems to be a lot. What's gonna happen if I play games or some more intensive apps?
I found when running Shadowrun Returns with the ElementalX 1.4 kernel http://forum.xda-developers.com/showthread.php?t=2389022 at 1.944 GHZ the back of the Nexus 7 gets hot. This worried me but I noticed when I installed the kernel was an option to use cool thermal throttling. I tried this and now the tablet does not heat up at all. You need to be rooted though to install the kerne of course not sure if ElementalX 1.4 works with stock though, I'm running the latest CM 10.2 nightly. It doesn't seem to affect the performance of either Shadowrun Returns or Wild Blood, the two games I'm playing at the moment, I still have the GPU overclocked to 487 and the Dalvik etc overclocked at the moderate ElementalX setting. . I think being able to run at 1.944 GHZ on my tablet with the cooler thermal throttling is better then running at stock and I believe that even some running at stock have that issue.
Hope this helps others that have this problem.

That's a good sign as you know the heat is being distributed effectively away from the internals. You don't need to be rooted to flash custom kernel. And setting different governors will have a major impact on your CPU.

You might be right about not needing to root to install a custom kernel though I couldn't find a definitive answer in the Nexus 7 2013 forums. I assumed it was needed from using custom kernels on other devices.
My device gets hot while gaming. When you are doing intense gaming like I am I'm sure pretty much any governor will max out the CPU. I know Intellidemand which I use does for sure.
When overclocking, heat is the enemy and it can damage, crash CPUs and even affect the performance of them. I believe if you are concerned about your Nexus 7 heating up (mine does for a good area between the logo and the camera when not using the ElementalX cool thermal throttling) then my advice is good.
Peace.
P.S. How the heck have you done 675 posts since June 2013?

Kernel is flashed separately from the ROM. Rooting is only for running apps like Trickster Mod to configure to kernel. Otherwise you can have stock 4.3 ROM with any kernel you want. Heating up will obvious affect performance due to thermal throttling but I was not concerned of damage even when the CPU of my 2012 Nexus 7 got to 80 degrees celsius from running overclocked performance stress test under direct sunlight in a case. If your CPU crashes then it's likely not overclocked correctly. Otherwise if it remains stable under artificial stress test, it will handle any game no problem.
I would really appreciate if someone explain me how exactly this function works?
I mean, tablet don't have fan, so how it keeps the cpu cool, and also what this option does to my nexus in order to keep it cooler?
I would not over clock this device. It us more than fast enough for any Android game.
Throttling does just what the word describes. In basic terms your cpu will be slowed down when getting hot and this defeats the purpose of over clocking.
I won't mention the instability that can be caused or the possibility of doing damage.
Just my thoughts.. To each how own and I do have my I7 pc cpu over clocked big time but it has a huge fan.

I agreed, throttling and over clock doesn't make sense but this CPU is underclocked and it is designed to go higher like the one on the galaxy s4 and the GPU is meant to go higher but due to battery life Google underclock it

Well , its not under clocked by Google, this is underclocked cheap from the factory , its just a lower bin s600 that has been rebranded as S4 Pro .. If it was regular s600 it wouldn't be underclocked .

When the CPU reaches a certain temperature threshold it begins to cycle down the CPU speed in order to cool down the processor. It makes the CPU start running at lower frequencies to keep it cool.
Exactly, so a quick oc and u got a better processor without worries of damaging the chip

Trickster Mod Thermal Throttling Settings
Hey,
If your CPU is getting hot (especially if it's overclocked and hitting 80 C or near to it) At 1944 the back of my case would get noticeably hot. I still say it isn't good for the CPU. From what I know about overclocking if any CPU gets too hot it can damage the CPU or degrade it over time. I definitely wouldn't want it even getting to 80C before it throttles but I found in Trickster Mod, even the free version, you can set the throttling to custom settings if you are rooted. Custom kernels set their voltages to scale depending on the clock speed which means lower clock speeds, less voltages, less heat. I'd rather keep the temps lower on the CPU then risk damaging the device or degrading it over time. Also you can undervolt the CPU at the kernel different clock speeds so it heats up less. You can run the free AnTuTu Benchmark stability test to see if your clock speed voltages are stable and will not crash your device. I have my CPU overclocked to 1944, thermal throttling down clocks the CPU to 1836 at 73 C, 1620 at 75 C, 1512 at 77 C and 1134 at 80 C. My voltages I lowered and are stable at 1944 - 1087500, 1890 - 1062500, 1836 - 1035000, 1728 - 1025000, 1620 - 1000000, 1512 - 987500. The lower voltages are undervolted as well but not going to list them all here.
Peace,
KedarWolf
P.S. When it was posted in this thread you can install custom kernels without rooting it is correct, I recall reading that at one point. Like it was said to use Trickster Mod, change governors or custom throttling settings you need to be rooted.
Bump bump
I'm in a huge dilemma right now, I want to install the "Ultimate" version of Faux's kernel but when I'm using it, my N4 always reboots on start up. From this, it's obvious that that my N4 cannot handle the OC at 1.8ghz and every time I attempt to lower the CPU frequency in trickster mod, my N4 reboots before I get a chance. Anyone out there have a version of Faux's Ultimate kernel that doesn't come at 1.8ghz by default when you install it?
You could try waiting for your device to cool down then booting it up and changing the frequency. I'm undervolted -100 and I'm using intellidemand and I have no problems with 1.8. The battery life is still unbelievably good - 88% with 1h SOT right now (ran quadrant 5 times).

Currently looking into the process of OC'ing and UV'ing. It would be cool to see what results you guys have got and what difference in battery life you perceive!
Im currently at stock ?

I have the same PVS CPU than you with 0,9 Volt at 384Mhz and 1,05 Volt at 1,5GHz.
I could undervolt 50mV accross the board; undervolt the lowest frequenz (384Mhz) to 0,73 Volt and overclock the CPU to 2,0Ghz max.
Im running Cyanogenmod with Glitch Kernel and use Trickster Mod for OC and CPU UV.
With Glitch Kernel I can even undervolt the GPU 100mv accross the board with an increased max GPU of 450Mhz.
(More is possible, but I nearly dont play games with my tablet)
With this I get about 8 hours of SOD time with Surfing.
When I'm on a long business trip and use my N7 for (Kindle and pdf) offline book reading I reach something like 13-15hours SOD time.

I know a bit how i can get to know my cpu's pvs stepping, but since you have the same as me, what is it exactly? And is it considered a fast, normal or slow binned cpu?

yup, run that for like 30mins on classic test, should be fine if it doesn't crash

I did that, but with voltages that are stable there, antutu crashes. And with voltages that are antutu stable, my device crashes randomly. I can run the scaling test with very low voltages across the board for more than an hour and it doesnt crash.
With other apps it just crashes.
This is an experimental undervolt that rarely crashes when switching apps:
I dont know which clock speed and its corresponsing voltage is unstable because the clock speed ranges from 384 to 1512 mhz and i dont have a crash log.
So I added 12.5 mV across the board, and this hasnt crashed so far!
But, being the perfectionist that I am, I want the Ultimate Undervolt. Is there a way to see what frequency you are running when it crashes?

I achieve stable 700mV at 1026MHz...
30mins stress run on "stability test" app and on stress run on "setCpu"
At 1134MHz the tablet freezes for the first time when I switch to 7875mV
Isn't it weird??
I dont think the stability test app is working. I could undervolt 1512 mhz to 900mV and have it run stable, but everyday use stable is with 987.5mV

Will you post your voltage table?
What are the Kernel setup settings that you choose and have you ever OCed to 2.2 and still get good undervolting?
