Anyone who undervolted his g2 ?
How low can we go ?

Very good question.
I hope some guys will reply who have already undervolted.
My max cpu frequency is 1190 MHz.
I don't think you need more speed on 4.2.2 (actually i'm on stock rom).
Gonna depend on soc binning for your device

My soc binning is 4 and I'm able to maintain stable undervolt by 50 mv (2.26 ghz @ 975 mv I think)

-62.5 here, I'm sure I can do -75 ( done it before) but it get micro lag, so I go to -62.5 works fine, nice and cool.
-100

I'd like to hear more about this! At stock settings my phone overheats and throttles badly. Been testing different voltages and at the moment I'm down five -12,5mV steps @ 962,5mV. Better temperatures and better performance due to less throttling.
I wish I had a rooted phone to do that

Where can you find the SOC binning value?
Edit: Hey looks like I found it
You can see the binning of your SoC in the last_kmsg located in /proc/last_kmsg.
You can also found it in /sys/devices/system/soc0 and search for pvs_bin and speed_bin or /d/acpuclk.

Hi! How much can IDEOS X5 be overclocked? Sorry for the noob question ;P
Sent from my Xperia Play using xda premium
Most ROMs have around 1800MHz limit... 1400 is safe, never tried it on maximum...
I use 1800MHz only when benchmarking.

I found that myne was not stable on 1800MHz. It worked on 1700MHz for a benchmark. I had it on 1200MHz max for normal use.
Great to know guys!

Aurora mod makes it 1 Gz default, so it should be safe for everyday use.
Max I got was 1.7 Ghz without problem.
-0.25mv / 1500Mhz gives more quadranet vs stock 1400 mhz and stock voltage
how healthy to keep it this way? any risk go up to 1600Mhz?
on last Omega JB rom i went from 4000 to 5130 in quadrant using this OC.
Thanks!
Of course higher clocks gives vigher benchmarks. Uv doesn't affect unless you uv to the point that voltage can't keep cpu stable.

The question: 1500-1600 levels risky to CPU ?
UV lower is good to keep temp lower...
From my experience, undervolting offers no benefits at all. Temperature remains the same and battery seems to be worse when idling.
with no overclocking and with stock 4.1.1 li7 i have 6300 scores in Quadrant..... with overclocking to 1600 mhz i reached 6700... no sense to overclock it

Which rom you use ?

Learning time!
-UV provides stability, its not to save battery. Its such a miniscule amount of volatge it wont mess up battery life, but it will help stability of the CPU...
-And when you OC, you need to undertand that it doesnt stay at the max speed on all four cores all the time. It changes to fit the needs of the user.
I think the CPU can reach 2.0GHz easily, i mean my single core Captivate with a Hummingbird 1.0GHz ARM cortex-A8 could reach 1.92GHz and stay stable with -50mV UV.

So I was trying to mess around with CPU profiles and I noticed that the low end of the CPU is clocked at 1GHz. If I lower it with Rom Toolbox, it just goes right back up after I leave the menu. the profiles won't stick, governors don't make a difference, and I'm a little confused.
Can someone shed some light on this for me?
I thought the lowest speed was 384 MHz? Install CPU Spy and check what it says.
It is 384MHz. The lower frequency change because of project butter that make the cpu run at a higher frequency when you touch the screen.

Dont you need a custom kernal in order to change the clock speeds?
sent via xda premium with nexus 7
No, we can already change it but it won't stick since it has its own frequency management.

Is this somewhat similar to perflocker in HTC devices? It had to be disabled to change any cpu settings AT ALL with the stock kernel.

You're right. I guess it just has its own profile to set at 1GHz when the screen is on, because the CPU Spy showed it in Deep Sleep/384Mhz for the majority of the night.

Hey guys, I'm new to the forums and fairly new to Hacking and overclocking android devices. However I have been building and overclocking high end PC's for sometime. So I am no stranger to the risks or processes of overclocking.
But I have some questions that maybe you all can help me out with before I start overclocking my Nexus 7.
Here are my Current Specs and Software:
Nexus 7 Wi-fi version
SmoothRom v5.0 + LeanKernel
Currently I am overclocked to 1500 Mhz Max with 204 Mhz Min + Stock voltage
I have been able to find information about CPU overclocking. But after extensive searching I have not been able to find much on Nexus 7 GPU overclocking.
1. Does my kernel support GPU overclocking?
2. If so how do I enable it? Or where is it located? and what settings should I be looking for (Names)?
3. If you need an App to overclock the GPU are there any that are free (Or at least one worth paying for?).... and which one if any supports my kernel?
4. Are there any good Nexus 7 CPU and GPU overclocking guides someone could point me to?
Basically I am looking for someone who is experienced in Nexus 7 overclocking, to point me in the right direction and help me with some indepth questions that may come up.
Thanks guys
What temperature is your CPU?

According to System tweaks App 39c to 40c while idling in that program. I don't know how accurate that app is though.... so if there is a standard better app to monitor your CPU/GPU temps I am all ears
I have yet to find an app that allows you to monitor your temps during load. Again if you can suggest one I am all for it.
Try trickstermod
Sent from my Nexus 7 using xda app-developers app
Download trickster mod from the app store you should be able to change the gpu voltage there
Sent from my GT-I8160 using xda app-developers app
Alright I will check that out. But what about GPU clock settings can trickster change those too??? And if so.... What setting am I looking for because I saw nothing referencing GPU clocks in those words
Sent from my Nexus 7 using xda app-developers app
It over clocks the GPU its on the 2nd to last page I think and you will see the clock speed and you can edit it, don't over kill though haha
Sent from my Nexus 7 using xda premium
Lean kernel doesn't have GPU over clocking settings. Try M-kernel, you'll find gpu settings in the specific menu of trickster mod.
Guys share your setcpu settings and tricks here for our XPERIA Z1

I can reduce cpu voltage on all frequencies by 40 mV but gpu lags at anything above 450 mhz(performance governor), also I'm on doomkernel and I can't properly underclock for some reason...

Mine is 1574 mhz max and 300 mhz min interactive row, stock kernel and @Nut 4.3 ROM..do i need to set on boot the default governor? Battery life is good and not overheating too much while playing NOVA 3..

If you do that all your seffings will go back to default like governors. There should be the option to set the same parameters on boot to keep all like you have right now. I don't know if on rooted Z1 there is this settings but should be because I remember I did all of this with android on different devices.

(I see a lot of people are using row though, so may need to test it and see if I notice a difference - that and undervolting..)
