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.

Hi all,
I'm pretty new to this forum and since the time i joined I was addicted to tamper with my phone to tune it up to my likings. Now that im done rooting,unlocking and flashing I got my phone running at 1.6ghz on stock gingerbread 2.3.4 (I tried ICS but i liked GB better).
Now my question is: How safe am I when I leave my cpu speed at 1.6ghz for daily use? It gets a bit warmer than stock when playing games, but I don't know the max safe temp and I don't know how i can check the temps using software. I can only check the battery temp. I assume this can't be related to the cpu temp?
For information: It boots up just below 30°C (86°F) and I have never seen it go over 40°C (104°F) when using heavy apps.
I don't have a clue weather i'm pretty safe or if i'm starting to dig a grave for my neo V. Can someone assist me further?
Thanks on advantage

its not safe to regularly overclock... the best way to monitor as you say is when the processor is in use... it becomes hot and because you OC - it becomes more hot...
use it like this if you want to cause some injury to your phone or someone or yourself

I know with overclocking is always a risk involved. But are u saying that 1.6ghz is way out of bound to be pretty safe for daily use? I also know that it's best to monitor when the cpu is fully utilised. But the thing is I don't know how to monitor the exact temps of my cpu and don't know how hot it is allowed to get without taking any damage.
Look, Xperia Arc S has exactly the same CPU like Xperia Neo (V) but is running @ 1,4 Ghz. In other words it's an oc by Sony!!
1,6 Ghz. Test it a while and report back.
I'm running my Neo V @ 1,4 Ghz when gaming and 0,8 Ghz for normal apps to save battery.
Good luck.
ps: on youtube u ll find videos running the neo v @ 1,9 Ghz working properly.

Increasing a frequency of a processor based on it's hardware specs sheet by ARM whether it would be done by a user or the device manufacturer is still like digging a grave for you're device. It's just a matter of whether you're digging the grave with a shovel or with a teaspoon.
Overclocking above 25-30% of the stock clock speed will significantly reduce the processor's life...the safest value is 1200-1300mghz...and the fact that Xperia arcS shares exactly the same processor is not true...it is overclocked by OEM...they do this in a different way so as to be on the safer side...you can go up to 1.4ghz...but that too is not safe...and speeds above 1.6 are just for those who treat their device as a use and throw item.

I oppose some of these. There's no other such thing as "it is overclocked by OEM"
1. ARM/Snapdragon doesn't quite give a full open source detail on their architecture to create different ways to mod their hardware.
2. Clocking part is handled by the kernel itself. By overclocking it you just add new and higher values and not actually modify the whole clock routine it does. I don't know the real reason why they clocked Arc S higher than other devices but only reason I could think of is "because it's flagship" I have already looked up the blueprint of our processors and well the default clock is actually 1.4ghz so 1.02ghz is still underclocked for us.

Looks like the Arc S and other 2011 Processors are different :/ noticed the letter T on the end of their names. The one without T is indeed only 1000ghz. And out has 1 version lower on the gps module too.

well thanks for that useful info mate...i dont have that much knowledge about cpu architecture...my views are fundamental...and yess...i know about that "t" in arc s cpu spec...thats why said it is different...now wheather it is overclocked by sony or by qualcomm themselves is not clear to me...and also wheather it has the same architecture ...i am just saying overclocking above a certain permissible value is not good.
like you just said...the processor in neoV is just 1000mghz...so it wont do any good if it is pushed beyond the limits.

Yup and all is clear to me now Arc S and other 2011 devices have different types of CPU arch. Wonder how did this "all 2011 devices have the same CPU" gone wild.
I did some searching on this matter, nobody knows for sure weather the CPU of the arc S is exactly the same architecture but factory overclocked or if it's a different architecture and therby safe to use at 1.4ghz unlike the neo v cpu. I would really like to know an answer to this.
The Xperia Arc S is using the same processor as lower clocked devices, but it's a higher binned part. This means that I can reach higher clock speeds while consuming less power compared to a lower binned processors. The same thing happens with PC processors.

After some research, I did find the spec sheet sans MSM8255T (arc S) but can confirm that it is not over clocked. What's surprised me is the official CPU for MSM8255 (neo V) has a range of 1-1.4 GHz & camera upto 12 MP. So, it would be safe to OC upto 1.4 GHz

There is no difference in GPU with either device running snapdragon 800 SOC's. The chips are exactly the same in actual fact, its just the higher capacity of tolerance for the higher clocked speed. So if a chip could take a higher clock speed during a stress test, then they were clocked at 2.3ghz...
But even though on the XZU we have 2.2Ghz (2.150Ghz to be exact) we are more than likely to be able to overclock it to 2.3ghz... similarly that the 2.3Ghz SOC could be overclocked to 2.4Ghz...
- Obviously this depends on developers we get for the XZU.. and if they want to put the many man hours into kernel development
As far as future proof is concerned... The 800 will be good for 18 months...

More than that it can only be that Sony actually set this limit for battery drain and thermal as well. While playing it become really hot. And if play and charge during the same time it become he'll. It remind me of the CPU that have on the HTC sensation and sensation XE, same CPU that was actually underclocked on the sensation.
As hamdogg just said, the CPU clock speed is not related to game, it's the GPU. All 800 SOC have the adreno 330

Hey, I saw that all CPUs are currently locked down to 1593mhz. Our chip should have 2x1.5ghz for general use and 2x2.1ghz for high performance tasks.
But in stock as in custom Roms, I see all CPUs locked down, max freq 1593mhz and no control over queue processing, either from hotplug or CPU front. Is there something I missed? Or LG just lied to us?
I know from thermal point of view that our device would not be able to sustain 2.1ghz for a long time, but if the frequency is not even available, it is a serious matter... +500mhz is not something to overlook!
If thats true, thatd be a heartbreaking, the first thing I look to before choosing a device, is clock speed
Unlock the game optimization
I checked on cpu-z and frequencies. With optimization on, it won't go over 1,5 ghz but with that option off it is easily jumping to maximum clock speed (faster battery drain). Stock rom, don't know about custom roms.

You mean game optimization in settings/battery? I think we do not have that option in custom ROMs (I am currently trying Aicp 12.1) and never changed it in stock. I will try going back to stock to disable that option and see if the frequency table changes... If it does, it will be a pre-requisite before flashing custom ROMs in our device. Still, it is something the kernel should handle.
I would underclock the device on my own, as I did with my good old G2, but not having the option for the CPUs to scale as intended is not cool...
Well, frequency table shows no change with stock, but somehow, CPUs 3 and 4 scale up to 2150mhz now.
I guess LG did not cheat in the strict sense of the word, but just does not want us to have control over our devices...

So... I was freaked out after reading this thread, so i rushed to check using cpu Z and it turned out that mine is clocked at 2.15, so i don't know what is wrong u
The Snapdragon 820 inside the LG G5 has a quad-core processor which has 2 cores clocked at 2.15 GHz and two other cores clocked at 1.6 GHz (1593 MHz), it's the way the manufacturer (Qualcomm) decided the processor to be, the LG G5 is not underclocked. Some users may get different results in applications like CPU-Z or AnTuTu depending on which core the application is based on.

The frequency table shown by kernel adiutor (or any kernel tweaking software) shows ranges 307-1593 for all processors.
I know the hardware behind, my first though was that LG underclocked it. Now I see the phone just hides its behavior and does not show the real table (or the available software is not able to see it).
We will need additional kernel development in order to effectively control the core speeds in our devices.
Case closed, thank you for the responses.

old versions of kernel auditor are buggy with the g5, they see it as a single quad core instead of big/little dual 2 cores. You need the newest kernel auditor.
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?

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..

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
Scroll down to assets and its in there.

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
