Overclocking question - Nexus 4 Q&A, Help & Troubleshooting

If I leave my phone Overclocked example 1.6 ghz as a daily driver, aka all the time, will I cut my cpu's life drastically? Will I damage my phone quickly? Were is the line when my phone is no longer stable and I couldn't use it as a daily driver?

Each chip has its own tolerances as well as each user having their own load they put onto them. There's too many variables to give a number.
I wouldn't say "drastically" at that speed (1.6ghz) ...
but a shorter overall lifespan of the cpu is the cost of OC. Especially considering there's no way other than undervolting to control the extra temperature generated. And that's no where near having a heatsink and fan or liquid system as in OCing a pc.

[Q] How overclock GPU?

I have nexus 7 3G 32gb with trinity kernel,stock ROM.And i have question how do i overclock GPU?
Use Trinity kernel toolbox. It has the option to set the speed of the GPU and adjust the CPU voltages

Can my GPU burn or something like that?Or high GPU frequency will cause only reboot?
I've read that the max recommended GPU speed is 484.Going much higher the battery will drain too much and will get hot. If you set the speed to high it will become unstable and usually reboot. It will reboot and rest default speeds long before it will have time to melt. Just don't use your over clock settings to be set on boot

1. easiest way, use the trinity kernel toolbox and adjust the gpu slider up or down.
2. or manually go to /sys/devices/system/cpu/cpu0/cpufreq/gpu_oc/ with a root file explorer(like root explorer) and manually edit the variable and save it.
yes, it can get very hot if overclocking the gpu. especially when playing cpu intensive games. worst thing is youll reboot if things go haywire.
Excessive voltage and heat can easily fry a CPU/GPU and other motherboard components, so be careful.

GPU under clocking

UI still runs super smooth at 128MHz, so will setting it to this have any major positive effect on battery life? If not playing games I'm guessing u won't really need all that GPU power.

Well, in technical terms it *should* give you better battery life because it's reducing stress on a main hardware component so it doesn't have to work as hard (the harder it works, the more battery it takes). Same thing with the screen; the lower the brightness, the better the battery.

Wouldn't it have to work harder for longer because it can't do anything as fast? It isn't like if you set the GPU clock to 487mhz it runs at 487mhz all the time, so ramping up to 487mhz would allow it to finish whatever it is doing faster wouldn't it?

Then wouldn't it be the same with the CPU? When I answered I was thinking like how a CPU would work. I understand your thinking though.

Well I would like to add that the 540 sgx can power the 720P in the Galaxy Nexus... That dino is significantly weaker than the Adreno 320 even over clocked. I run 128 only and it works fine for games and even HD videos(YouTube). To confirm I tried Most wanted, dead trigger, temple run, riptide,etc and there weren't any issues(also toggled vSync). And if you use benchmarks like Epic cidel or antutu you'll see the frames are still pretty high.
So I'll say that 128 or even 200mhz is sufficient for this GPU and most purposes. However a good I/o scheduler and governor are still recommended.

I think another advantage if it runs what you want at a good frame rate is less heat.

Phone getting heated

Hi guys I dont play much games on my phone ,
Yesterday when checked found modern combat for free on samsung apps downloaded installed and now when I started playing it gets heated very soon is this normal or is it due to over clocking of cpu and gpu?

Hello, what is your current voltage for your cpu and gpu? And frequency (cpu/gpu)?
Undervolt probably can resolve the problem!
Sorry for my english, i'm french!

It's normal. I haven't over or underclocked or overclocked my phone and when playing highly intensive graphiv games, it heats up. If you have a case on it, that could contribute.

Having a case on heats the phone up? I haven't rooted or played any intensive games on my phone. I do have a case and I am noticing the phone heats up quite a bit when you charge your phone or if your 3G connection is ON for long. I think that's the reason my SD Card got busted, due to excessive heating. Can anyone confirm the phone heating up coz of a case?

Yes guys ive a case bit when playing I remove it and the heating usually happens on the front and back side of my screen where the back camera is located
Ive set max feq to 1.8

If it isn't turning off then you are fine. A quad core cpu with a gpu on board will get warm in the designated area, especially given the fact there is no ventilation.
Your cpu set to 1.8ghz and voltage?
You can test decrease voltage by 0.25mv to reduce heat and better battery life.
For me actually 1.8ghz = 1250mv

perfect now
What did you guys use to set the frequency and voltage? I'm on omega v15 TW based and tried to use setcpu but it won't let me go higher than 1.6 Ghz

Its the case with only a few games. I hope it will be fixed with an update. The XXDMC3 firmware is said to have come up with a fix already!
Hope for the best ....

How To Undervolt

I've seen a few post on how to undervolt but I'm still not 100% sure how or if I should, I'm guessing it gives a little bit more battery life ? Also what app would be the best to use ? And the best values to apply

you have to install custom kernel for undervolting.. and it does not give you battery life..it reduces how hot your phone gets..
It can increase battery life actually, not hugely but ARM processors used in phones use a few watts, wattage is calculated as voltage * amperage, less volts going through the lower the wattage, ergo lower power consumption resulting in extended battery life. /rant
OP you will need a kernel that supports UV (pretty much all non stock) and a UV interface, I prefer trickster mod. Look for core voltage and knock it down a step (-25mV). Then stress test / benchmark, if you don't freeze / reboot then you can knock another 25mV off, keep doing this until you get the minimum voltage your phone remains stable (for me 1025mV @ 1.5GHz). You can then set for the options to stick on boot.

Mulit-core hacks

So I have a very thought out question now I have a 4 core phone right? Well my battery life is below average and I was wondering if I had all my cores running at once would it balance out battery life? I just need some help from someone who knows about all this and are all cores mandatory?
Sent From My Liberated E970
You can select how many active cores are activated with trickster mod and (necessary!) a kernel that supports this.

I know how to and can with my kernel but I need to know if more cores are activated if the battery life will be better or worse
Sent from my Optimus G using XDA Premium HD app
I would definitely take a look in to what my batter usage is and how to control that before I worry about the cores. Just my two cents.
P.S. I am sorry but I believe the Multi-core in the title is spelled wrong.

More cores active would mean more processing power, and more processing power requires more energy(atleast on the same cpu), so disabling most of your cores would result in better battery life, maybe by a little bit though.
Hahaha I didn't realize it said mulit
Sent from my Optimus G using XDA Premium HD app
useful topic
It seems to me that by disabling cores wont make a difference to your battery life, only to your performance. It doesn't matter if 2 cores work for 5 seconds or 1 core works for 10 seconds, it is practically the same power consumption
Play around
I would say download CPU-Z from the Play Store and look how much Cores are active and which clock they're at.
Then flash a custom Kernel, which lets you control the clock, govenor and how much cores are active, undervolting may increase your battery life too.
Play with the settings (PLEASE DO NOT RAMP UP THE CLOCKS or set the voltage to the lowest point you can, it may break your phone, stay reasonable, it's not my fault if your phone bricks) and look what's best for you.
Pro Tip: Take a look at the different govenors and look what they do. Google them!

I hope I could help you a little
Im using trickster mod and I know about all of this I studied up and have undervolted by 200 MV stable but I'm using the hotplug settings to 1:2 so not all 4 cores are active and I get almost two days on one charge!so I guess that does mean less cores use less power
