Is there a way to overclock at Xperia m2?
If not, would it be possible for a developer to make a kernel to overclock both the gpu and cpu?
Thank you in advance ...
Sorry my English, I used a translator to create this post ...
I don't think that overclocking is a good idea since the architecture of the M2 is kinda bad. Sony even underclocked the CPU so the phone won't get hot or worse. It is possible
My previous phone was a Xperia E Dual.
It is a low-end single-core 1 Ghz (1000 Mhz) phone. But it has a kernel with an overclock to 1.8 Ghz.
Yes it got really hot at 1.8 Ghz. (About 40 °C after 2 minutes of gaming, then throttling back to 1 Ghz) But for burst workloads (like loading an app) the 1.8 Ghz was good.
If anyone could build an overclocked kernel, I would instantly flash it.
No, the phone isn't slow, but it could be snappier. (Try opening the settings app...)
Still waiting for an overclock.

Hi guys
I downloaded the quadrant standard application on my Captivate. Looking into the system info i observed the following
1. CPU : samsung cortex v7. I thght the processor was a v8? I dunno whether the processor info is right.
2. The processor speed is displayes as "800 MHz"
Max freq ; 1000 MHz
MIN freq : 800 MHz
Whatz going on here?
Can someone explain this?
Please run the benchmark and lef me know!

the 800mhz I would assume means it is throttled down.
My results...
Name: ARMv7 Processor rev 2 (v71)
Current freq: 800 MHz
Max req: 1000MHz
Min freq: 100 MHz

Just ran the benchmark and got the same thing. Please don't tell me this thing is underclocked. if so is there a program out there that will bring it up to speed?
The processor is a Samsung S5PC110 Cortex-A8 and uses the ARM v7 instruction set. It's not a version 8.
there is an APp to change your CPU clock. Don't do it though, nothing on android requires those extra 200 MHz yet. If your thinking about UI Lag, this is a software issue and not a consequence of the throttled cpu. Hang tight for a fix from developers.
With the software fix and throttled down cpu, this phone is still faster than the newest phones running 2.2 (Froyo)
SetCPU will let you force the frequency. But you shouldn't need to use it, 800MHz just seems to be the Hummingbird's idle frequency. The CPU probably just idled while the graphical benchmarks were being run.
CPU in phones never runs at 100% at all times that would kill battery , you can force it if you root your phone but that is counter productive , as it goes from anywhere from 1% to 100% of its speed when it needs to , during intensive usage or benchmarking it will reach 1000mhz , but if all you do is read text it will conserve battery.
Its obvious from this info below
Current freq: 800 MHz
Max req: 1000MHz
Min freq: 100 MHz
Yes, the Cortex A8 is an ARM7 processor. The older CPU's used were ARM11 processors.
Thankx for the info guys..
I checked again and for some reason i got confused with the processor and was writing the post from memory (my memory ). it says ARMv7 Processor rev 2 (v71).
And yes i do think the 800 MHZ is pretty fast.
I just need to get rid of the samsung UI and switch to stock android.

itzz(AN)dRoiD
The spec sheet lists 1 GHz, and spec sheets show the operating frequency so I would assume that the CPU can run at different speeds for different workloads. Try running a couple heavy applications in the background and check it again. If all is well in the world it should clock upto 1 GHz.

The processor is NOT 800mhz it's just throttled down to 800mhz cause of not needing the full 1ghz speed. That saves power and battery life gets extended. Laptops and desktops do the same thing.
so in other words it basically adjusts oh and also maybe the ARMv7 infrastructure is better then the 11 one
yes i do get the idea

I do get the idea!.. i inquired about it bcoz nowhere it was mentioned that the processor was underclocked.. So basically the ideal processor speed is 800MHz and it can be overclocked to 1GHz is the way i see it!
sorta like that more like the speed auto adjust to your needs i think
So what kind of scores does this phone get in comparison to other new Android phones with or without 2.2. I am curious between the Quandrant scores of Hummingbird (Galaxy S), OMAP (Droid X), Snapdragon (HTC HD2/EVO 4G).
Thanks.
well the hummingbird beat the evo 4g in graphics and cpu power just search captivate benchmarks on youtube the channel name is androidandme
with mimocans lag fix ive seen people get scores as high as 1700(nexus one on 2.2 gets about 1250).

Hello guys,
Since i`ve seen so many debates about single vs dual-core, today i was bored and i tested with antutu and quadrant this thing.( I know that benchmarks isn`t a real proof in day-to-day performance )
WANT THE SCRIPTS FOR UNDERVOLTING AND FORCING CPU1 ONLINE OR OFFLINE ? See 2nd post
SO , what I actually did:
-flashed a freshly new rom ( using elegancia 3.1.0 for about 2 weeks and i found to be very stable and smooth with better battery life than any other rom i`ve tested)
-flashed latest bricked kernel min 192 mhz max 972 mhz with gpu oc @300mhz, lagfree governor, I/O deadline, both cores online via init.d script, booted and tested with antutu and quadrant and then i let the phone settle for a while to see what is the power consumption in stand-by with battery monitor widget.
-after that, i flashed bricked kernel with only max speed change to 1836 mhz, cpu1 offline via inid.d script and made those tests again
Here`s what I got:
Antutu: 4827 (both cores online, clocked @ 972 Mhz)
Quadrant: 2592
BMW: -19mA
Antutu: 4593 ( cpu1 offline, clocked @ 1.836 Ghz )
Quadrant: 3393 ( cpu1 offline, clocked @ 1.836 Ghz )
BMW: -28mA
Those numbers doesn`t reflect exactly the user experience. Some apps opened faster with 2 cores, some faster with only 1 core clecked at higher speed. The only major difference i noticed was in the browser( stock ICS browser) where the more fluid experience was with both cores on.
I`m gonna test those 2 configuration further to see which one has better battery and post some screenshots.
I will add a poll to see which configuration you think is the best.
Be aware that SoC are not created equaly, so the UV script or OC will NOT work with all devices.
Unrar the archive and choose what you want
This files needs to be copied in /system/etc/inid.d and then set the right permissions ( read: all 3 needs to be checked; write: owner checked; execute: same as read) . You need a file explorer that has access up to root ( i recommand Root exploer)

I knew that, but i wanted a more real-life experience, and in my opinion there isn`t that much difference in lagfree vs performance. I ran benchmarks 2 times and the scores where almost identical
Please be aware that because of the instruction sets hard coded at low level into the cpu it doesn not mean that 2x 900mhz cpu cores is equal to 1x 1800mhz cpu core because of the way in which the second core is utilised. Its exactly the same with pc's hence why sometimes an AMD cpu with 2 cores can give a better real world performance benchmark than an intel cpu with 4 cores. the same applies vice versa, it just depends on what instruction sets were used and how the cpu is used. Benchmarking stuff like this is not a reliable way to test

Thanks (I'd use thanks button,but i'm limited to 8 oer day) for clarifying this for me and any other users, this post should be sticky because many members on xda think that way. I am aware that 2x900 doesn't equal 1x1800, but I didn't knew the exact explanation. The only reason that I did these tests was to see which configuration gives the best battery life. Their not equal, but acording to antutu, quadrant and end user experience they are comparable
Thanks for your time in doing these tests... It might not be reliable but it was interesting to know bout it... Im curious between the two tests though, which test puts the cpu under more stress? the first test shows awesome result on the battery so being single core might stress the cpu more, im guessing

Does anyone know if it will eventually be possible to overclock the GPU in the Nexus 5 to match the S800 MSM8974AB chip?
The S800 chip in the Nexus 5 is the MSM8974 chip which has the GPU clock of 450MHz, but there is another version of the S800 chip called the MSM8974AB which has the GPU clocked at 550MHz.
Here is a link for anyone that is interested in seeing all the differences between the MSM8974 and the MSM8974AB
http://www.androidbeat.com/2013/09/difference-snapdragon-800-2-2ghz-2-3ghz/
It will definitely be possible with kernels. Don't know how safe it will be to overclock by 100mhz, but on my HTC One Elemental X gives the option to overclock from stock 400mhz to 550 (very bad for the device though). So the Nexus 5 will definitely be able to hit 550 as well.
Adreno 330 overclock 450MHz to 550MHz
Hello,
Is there any update about this?
I Overclocked the CPU to 2.5GHz via a custom kernel, but I am unable to pass the 450MHz of the CPU.
Please let me know if you have a solution.
Thanks
which device use MSM8974AB chip?
I have the Z1 also, which has the same chipset as the N5. There is a custom kernel for the z1 that OCs the GPU to 533mhz which I run stably with excellent battery life. So I'm sure it's possible to do the same with the N5 since it's the same processor. I'm sure one of the smart devs here can look at the github posted here: http://forum.xda-developers.com/showthread.php?t=2448613
my GOD, what did i just read
http://www.qualcomm.com/media/blog/...gies-newest-snapdragon-805-ultra-hd-processor
Adreno 420? As a heavy gamers, this thing really make me annoying -_-
I have 600MHz GPU overclock implemented in my kernel for the Xperia Z1, which uses the lower binned version of the msm8974 (the one that comes with a stock clock-speed of 2.2GHz).
We have 450/487.5/533/600 MHz scaling steps.
You can take a look at the OC commits here, it's pretty straight-forward:

Is it possible to control also gpu voltage?
You got 600mhz at stock voltage?

It is, but not yet implemented on the nexus 5 custom kernels.
Also mhz does not mean voltage (V) or (uVolts on this case). MHz means a frequency of 1 million times per second (used on this case for CPU, GPU, RAM speed)

True, but @Carter07 is right that if the maximum allowed voltage is too low the GPU won't be able to sustain higher frequencies, as those demand more power.
The 600MHz OC is stable with the stock voltage, though, at least on the Z1 it is.

indeed, I misinterpreted him
You can flash Bricked kernel and use Kcontrol to force-overclock your gpu up to 650...but I wouldn't recommend anything above 550 since you will get little to no performance and it'll consume a lot more battery
Is there a huge performance boost noticable if you oc the cpu? And what's about the battery life?

There's no recognisable boost in performance apparently. And yes,battery drain will be higher if you raise voltages and you also risk damage to the core.

CPU or GPU? Some users reported less lags (OC GPU) with energy-consuming games.
Hi
I have try many kernels(and ROMS) and my phone keep to be unstable-crash after oc over 1.3 ghz.
Do you know why?
Thank in avdance!
maybe beacuse is too much you cant do it just like that.you can oc max to 1.15-1.25 for a daily use
i managed to get my phone stable 24/7 @ 1.3ghz with a decent kernel (i think i'm currently using signed_shazo's_kernel but not sure anymore) and voltage control to set clock and a bit more voltage on the cpu @ 1.3ghz... your battery will suffer and phone gets hot with heavy usage but the performance gains are substantial)
hope this helps
I'm using stock emui on android 4.4.2. I recently rooted my phone and noticed that the cpu frequencies are really weird. First of all all cpu over/underclocking apps showed max of 1.3 Ghz and min of 1.2 Ghz. Shouldn't max be 1.7 Ghz? Even more weird was i couldn't change the frequencies to anything else. I wanted to reduce the heat that 1.2 Ghz min frequency causes and thats why I rooted in first place. I managed to get frequencies stay by using Trickster mod's freq lock. But I'm still wondering if its normal for my phone to get hot and can I set max freq to 7.8 Ghz for gaming? And no, the power saving thing aka phone manager doesn't change anything else but increase battery life when I disable it.
That's for the A7 cluster. A15 cluster goes up to 1,7 GHz.

I just noticed in another cpu tweaking app that it showed only some of cores can go up to 1.7 Ghz and other only to 1.3 Ghz. This furthermore confirms it that only half of cores are cabable of 1.7 Ghz. http://www.devicespecifications.com/en/model-cpu/6dee2d53
Too bad this info isn't almost anywhere at all.
