Hi everybody.
It would be nice if someone could make Kernel/Rom with possible GPU overclock.
By my knowledge in Xperia P is Mali-400MP with 1 (i find somewhere 2) core fragment with default speed 200Mhz.
In older SGS2 there is Mali-400MP4 on stock 267Mhz.
Is there a way for safe overclock Mali GPU in Xperia P to 267Mhz or maybe 240Mhz?
Best regards
no, not yet, and maybe never.
it will only gives problems (battery drains much faster, phones become very hot etc.)
NovaThor chips are designed for low power consumption, also overclocking the Cpu the heat produced still low.
I think that the biggest problem is the driver of chip and its documentation
mali 400 stock Frequency min 240 max 395. why give problems (except for battery )

it will give problems for sure but on some heavy games our phones needs gpu overclock
Overclock only turn your phone to heater and energy eater, no to lamborgini
PS:sry for my bad english
If not overclock, atleast governor control? And I/O too if thats possible?
Is this possible atleast?

max overclock on my s2's gpu is 520mhz (wid custom kernel) bt it requires 1350mV .. sufficient enough to make a fried omlet...
being an ex xu user.. i have found no game (atleast among what i play) which ran properly on s2 bt not on xu.. extra cores gives better benchmarks real life perfomance is games is almost similar...

This thread is purely a discussion about our phone's processor ability to be overclocked.
Does anyone here have any idea how our beloved xperia mini/minipro/lww processor can be clock as high as 2GHz as opposed to its default clock speed(1GHz)? If you carefully goes beyond our phone subforums into the realms other phone you can see that much of the phone there can't be overclock as high as our phone can go. Eg; other phone with 1GHz processor can only be overclock to 1.3GHz.
Any ideas? Developers facts can be very helpful.

Well 1600 mhz is stable for me,I will try 2000 mhz as soon I install supported rom.About 1300 mhz max for some models looks stupid to me,I didnt read post that says that.

I've tried 2GHz on my phone, seems to be okay w/o any instability issue.
Fortunately our phone isn't maxed out at 1.3GHz, almost all kernel for our phone support up to 2GHz, what I meant is, phone like x10 seems to be maxed out at 1.3GHz. Just small increment from 1GHz to 1.3. While our phone can go all the way up from 1GHz to 2GHz doubling its default clock speed.

i've only tried to run benchmarks on my phone up to 1.6GHz,
did not try higher speeds because i am worried about the CPU might break...
as per x kernel latest release, they have set the limit to just 1.8GHz.
seems that would be the safest our CPUs would reach but still its not same for all units.
i am not completely aware about the technical specifics of the CPU but it seems that it could have been made that way.
the only thing that would limit the CPU capabilities is the temperature and the battery capacity, since running an overclocked CPU on a 1200mAh battery is not that efficient.
You're not exactly correct OP.
My Active, with the OC Spartan kernel, goes up to 2Ghz on my device and its perfectly stable.
On my Desire Z however, stock Mhz is 800, and i have oc'd it to 1.9Ghz stable, thats over 140% (russian election pun not intended ) oc. It is one of the most highly overclockable devices yet.
So it's not only our devices that go to 100% of stock speeds. Ill remind you that companies, take some "malfuncioning" processor chips that might have a specific part of them not working, lower their speeds to make them stable chips, and then ship them out to manufacturing.
That is why some devices dont go over 1.9Ghz. Its just a matter of quality of the CPU. I know this because back in the days of the ATI9500, which was actually a ATI9700Pro, just underclocked because a pipeline was malfunctioning, so instead of throwing them away, they locked the pipeline and sold them as a lower budget Video Card. With some tools though you could unlock the pipeline and if you were lucky you could have an ATI9700Pro in the price of a ATI9500
I have one question while we are on this topic.
Our phones have MSM8225 chipset while the Arc S has MSM8255T (clocked at 1.4 GHz). I'm curious, is there any noticeable difference between these two chipsets? If there isn't why aren't our phones clocked at 1GHz?
The reason these go by 8255 and 8255T are stated in the post i made above. Same chips, different quality. It seems that not all 8255 can be stable up to 1.4-1.5Ghz, so they released a cheaper 8255 line that is clocked at 1Ghz.

You are completely right but I have to say that architecture has something to do as well on my old x10 mini arm6 I had a 600 MHz processor going at Max of 800 and something and now my lww arm7 can go as high as 2 ghz lol.

The maximum CPU clock frequency is placed by kernel developer, what he thinks is fine. It is not that phone's CPU can really put up with that high clock frequency.

Sure then the cpu had nothing to do when you clock a 600 mhz cpu to 845 mhz and it crashes?? come on that is a lame thing to say in this thread

What I ment, was that the actual maximal overclock frequency, where you can set it, is set by kernel developer.
You can set the CPU max frequency 1Ghz, 1.2Ghz, whatever. But the really maximum, which you can set, for example 2Ghz in Rage Kernel, 1.8Ghz in X Kernel, is set by kernel developer.
It is not tested that phone can put up with that high frequency. That is your own responsibility to try and risk.
Imagine cpus being made like cookies.Although you use the same ingredients not all cookies are baked the same, not matter how good your oven is.Cpus get out of the "oven" and tested for stability.The less stable are clocked lower, the more stable higher and that depends from the voltage they need to run and the maximum safe temperature that is allowed so the chip can last long time.So they say that chips which fall between A and B specifications (temp voltage etc...) are going to clocked to 1 GHz and those that range between C and D to 1.4 GHz.But those who are close to A are not the same as B, same with C and D.That's why some cpus clock better than others even though they're clocked at the same speed.At least that's how computer cpus were made if i recall correctly.
Its marketing trick.
Why should I buy WT19i when I can buy Arc S with higher clock rate.
Same processor because if processor is diffrent they would need to make new S1Boot,if in arc s is new bootloader patch wont work.

is there any option to raise SGS3 CPU to 2000mhz or something like that?
EDIT: NEW AS 14/7
kk so i guess the highest and most stablest cpu might be till 1800mhz
1and what about ram? there is any overclocking for ram memory? (couldnt find anything about it)
2what about GPU?
not yet, i think the highest clock right now is 1.5 for the sgs3
and RAM, NO you can not get MORE ram, you can eliminate apps that eating up ram to free some up but no way to get more ram.
is there any need to overclock this beast lol its fast enough

He wasn't referring to getting more RAM though was he? It read to me that he wanted to see if was possible to increase the clock speed of the RAM along with the CPU.
yep just wondering if there is any option for that as in SGS1+2
do you guys think when there is OC for s3, it will raise CPU to 2000MHz ?

Already there OC/UV running 1500Mhz right now. Max 1800Mhz.
Look into de developers topics for the kernel..
Ive looked there.. stiil misunderstand something-
there is any OC of 2000mhz now?
Note that the Exynos 4Core CPU is still not very well understood and may well get long-time damage when ramping up the clock speed aggressively.
Is there actually ANY need for going so high except to show off?
You'll be measuring any speed improvement in loading things up in microseconds because people say Samsung still hasn't fully optimised the phone to the OS yet, so I think it's a bit pointless stressing the phone that much.
1.8GHZ is currently the max however with kmemhelper you should be able to change the last frequency to 2.0...
Hell I'll even find out the script for you if you are mad enough to try it first

I doubt you'll get it 2GHz stable anyway. From what I've heard most people have theirs crap out at 1.8GHz.

1and what about ram? there is any overclocking for ram memory? (couldnt find anything about it)

to make it clear:
i wanna know which ram overclocking is available to do on the SGS3 as long as the device still stables.
same with GPU and all those stuff.. there is a really good lvl of OC like in S1 S2?
still waiting for help
I would go for Siyah kernel and try 1.8 GHz then under volt using voltage control or extweaks app. Most phones can go 100 mv on all steps except maybe the very highest clocks.
gpu overclock is not possible yet

OC of the ram is connected to bus speed and this is very different to the fixed bus in the sgs1 so nothing like live oc is possible. Still 400 mhz bus speed is 4 times faster than the CHAt!
Sent from my GT-I9300 using xda premium
I`am running RGUI v7 rom and siyah kernel 1.3.8a. My clockspeed is 1600 Mhz and is rockstable, snappy and battery life is great.
I don`t go any higher for daily use, it doesn`t make much difference in speed and i think it cuts down your cpu-life.
ho so no LIVE OC is available now? (like in S1 and s2)?
well hoping it will be possible to add those functions(live oc, ram, cpu, and more..) in Android JB 4.1
My Captivate (SGS1) can hit 1.92GHz... So I think that a CPU with a stock clock of 1.4GHz can hit 2GHz easily. We will just have to see. I am not pushing this phone though. I don't have $700 to replace it.

That's not depended on the ROM but on whether the hardware allows to modify the values and if kernel developers figure out how to do it.
Ok i searched google and here but didnt find a decent answer..
its just noob questions but i hope you guys could give me simple answers..
1. apart from getting better battery life, what's the difference between 1.2ghz with no undervolt and 1.2ghz with, let's say, -50mv undervolt?? what's the advantage/disadvantage?
2. what's better for performance/battery, 800mhz no undervolt or 1.2ghz with -50mv undervolt?
3. what's the gpu for? is it for games only?
4. is the cpu or gpu which controls the browser, i mean for rendering web pages/images/videos? for example, if i set the gpu to the lowest possible tweaks and underclock it will it affect how fast the browser render pages?
I hope you bare with me, it's been a really long time i want to ask these and find answers..

1)If you undervolt the CPU Core(s) gets less power, which is better for battery life, but maybe will decrease performance @ this CPU step
2)Performance: for sure 1.2Ghz (800Mhz is less than the Galaxy S )
Battery: you have to find out yourself which Kernel/ROM/CPU-config fits best for you!
3)The GPU is for everything grafical in some way (especially for Games etc.)
4)Maybe...
I really don't know but I don't think only the GPU "renders" webpages

Hi folks
I was curious are there any driver updates for the device itself ? coz Adreno330 is very common graphic chip in Z2s rank. (like when i had nexus 4 there was a new graphics driver...)
Anyway to overclock the GPU ?
Are there an notable mod ports etc other than X-Reality ?
What is Viper4Android ? How can i install and config it for Z2 ? Is there any pre-configured flashable ?
What other sound mods are there to increase volume with least quality decrease ?
147 views yet no reply ?
what a great community, WHERE is everyone ?
I think there's very small interest in overclocking the gpu .
Also cpu oc is pretty useless since z2 cpu is 2.3ghz fast , a 2.7 would not make a noticeable difference but will heat and drain battery more .
I preffer undervolting and running stock freqs for a better battery life and lower temps .
hi all,
is there a way to undervolt and or OC the CPU and GPU?
I remember reading a article a month ago about a GPU OC, but somehow that's it. No way to download the mentioned app etc.
Is there anything for the Mi 10 / SD 865?

According to this news oage, we still have some potential left in our SD865
Xiaomi Mi 10 Overclocking Has Improved Significantly
he game performance has also been improved in addition to the higher running scores of the overclocked Snapdragon 865 models.
www.igeekphone.com
here is even a XDA link to another phone without any links to the app itself...
Abandoned
abandoned.
forum.xda-developers.com
so there is a way to OC and UV the SD865
That isn't what it appears to be to me. It appears to be an ongoing project to oc/uv the snapdragon processor and gpu and so far all they've done is managed to change the ram clockspeed. The pros of undervolting the ram is less heat but the cons is bottlenecking under load because ram uses voltage in correlation to clockspeed. If you overvolt the ram it produces more heat, processes more data but stability goes out of the window completely. This is NOT CPU/GPU core clocking and won't have any effect on the cores whatsoever, only data throughput.
I'll stand by my word coming from HTC to Xiaomi, both snapdragon phones, you can't overclock a snapdragon because they're not underclocked. It has been that way for a long time. What they advertise the chip as capable of is what the chip is capable of as by design and will actually be that way in the field.
If you want proof just take a browse around the later HTC phones and you won't see anything about core clocking, probably not ram volting either..

No offense, but have you read any of the two links I posted?
They literally explain, that they changed/overclocked the GPU frequency to 865mhz
stock frequency should be 587mhz.
They did overclock the GPU.
They even proved it by showing some benchmarks.. and compared it to the SD888
And this is the first time I read, that SDs are not overclockable...
865mhz is the bus and ram frequency. The cores are in the ghz.
All that has been achieved is a higher throughput and that equates to more heat and more used power. This stuff is well researched.
I honestly dont get, where you getting the RAM OC thing.
They do not use ddr7 or ddr8 on a mobile SoC, because the tech isnt there yet...
If you search for the Andreno 650 GPU you will see its specs that it is clocked at 587mhz (and not the Ram).
They are of course adjusting the ram timings too, but the xda links tells the following:
"2. edit your settings in the 3 tables. (start with adding the extra step form 865+ to 865)
3. press "Save GPU Freq Table" after editing any page, before you move to another."
If you want to stay with your resolution on this topic, it is fine.
I just want to know where we can get the KonaBess app, because google only links me to chinese pages and somehow this topic isnt as popular as I thought.
Not 100% sure if this link is allowed.... https://github.com/xzr467706992/KonaBess/releases/tag/v0.12

Just a heads up, not all snapdragons are created equally. That said, there is definitely performance left to gain via OC the adreno 650 gpu of the 865. I'm currently running a massive 930mhz on my adreno 650 and a very small cpu OC and with that, it blows the 865+ away in benchmarking and trades wins with a stock SD 888 with CPU and GPU bench scores. Any OC'ing you do I highly recommend doing a stress test before thinking you're stable.

Thanks for the heads up, I am already aware of the "silicon lottery".
I am amazed how much juice is still left in the SD865, that OCd it can even beat the 888 and is more consistent.
Do you use any App to monitor your temps and how did you OC your CPU? Afaik KonaBess only allows GPU oc?

Hi, I can't seem to find any tutorial online on how to overclock. Could you help me out ? I am gonna order a Black Shark 4 with the Snpadragon 870 soon, which is the best cherrypicked chip along the same chipset as the 865, which means that it's more likely to be a silicon lottery win... Can we get in touch on Discord ? My username is Meli #6318.
please guide me to modify the necessary things to overclock (kernel, file...)
anyway i still want to overclock it and gpu

How did you oc the cpu ? and is it possible to oc the gpu of the sd870 which is also the adreno650 but I’ve heard that it’s locked by Qualcomm trust zone , is it just a problem with sd870 or even 888 and 8 gen 1 ? Thanks in advance
