Gpu underclock? - Xperia Z5 Compact Q&A, Help & Troubleshooting

Due to overheating issues I've underclocked z5c cpu ( using this method and flashing the recompiled kernel ), is it possible to do the same with gpu? Which file do I have to look for?
AFAIK Adreno 430 runs up to 650 Mhz, 450-510 Mhz should be enough for my standard usage.

I have no idea but you could take a look at the Adreno idler commits...
Here is one I did to add 27Mhz as the lowest clock (might be a good file to look at), instead of 180Mhz...
All creds go to @arter97

Please take look...

I just saw the specs of galaxy ace.
Same adreno 200 gpu as our's and the same processor msm7227 but clocked at 800 Mhz....wtf?
I couldnt overclock my phone to a stable 806 ever
Can anyone make any comments please??

Kernel matters rolleys.
Sent from my LG-P500 using XDA Premium App
Yes, Its due to kernel only. And not to worry so mush. What FK has given us till now you can use @ 768, It's not bad at all.
lol binodray, u know about android or ur just acting like u know??
we cant overclock because the msm7227 in our device is connected to cheap cables and busses and probably cheap ahb or something...
thats y some people are able to overclock to 806 and some people are not able to...
No dear I don’t know anything.
On a short note
The MSM7227 is ARM 11 family 32bit Qualcomm MSM7225 processor. This series seems to run PLL2 at 1200MHz, which is why they are capable of running at 600MHz. (1200/2 binary thing).
what is over clocking?
Over clocking typically refers to running a CPU at a clock speed higher than that for which it was originally designed. And the kernel is told that it is being run at a higher speed (In realty it’s not).
Why phone crash?
When phone generate very high voltage due to increased clock speed we have kernel panic in result.
How we solve this?
As far as I know if dev can alter UV table in kernel we can have processor with 1728 which is 864. This means there could be one kernel supporting OC frequencies up to 1728Mhz (lets say 1728,1600,1500,1400,1300,1200,1120), and user could choose which ones he wants to use (eg 1400 and 1120, disabling the rest).
Hope this will make you clear why we need kernel and why OC is based on kernel codes.

[Discussion] why our phone's proc can be o'clocked so "crazily high"

[Discussion]
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.

CPU vs GPU overclocking?

just wondering, there's so much talk about overclocking CPU.
why no discussion on overclocking for GPU? is it possible?
i think if the higher GPU clockspeed improve performance even more than CPU clock speed, doesn't it?
if i understand correctly, galaxy nexus GPU is the same as galaxy S1. but with much higher clock speed. So the GPU speed can be made higher right?
Some kernel, as Siyah allows you (with extweaks) to overclock gpu up to 400 mhz, but I think this is useless, no app need more than 200-267 mhz.
A good idea can be downclock gpu and cpu frequency and decrease voltages to save battery.

Gpu steps are 3. According to information provided by extweaks default frequency values are 160, 267, 267, but you can set as you want.

That is the "Performace" setting of siyah(160, 267, 267). Or maybe it is the default but siyah considers it as a performance setting

Snapdragon 810 v2.1 with 630 MHz GPU clock speed?

[email protected],
i´m not really shure but as far as i know the 2.1 revision of snapdragon 810 cpu should have a gpu clock speed of 630 MHz max., correct?
So, on my device the max gpu speed is 600 MHz. so i think the "old" 2.0 revision is buildt in or am i wrong?

Sony merged commit to enable 630MHz on Z5, but they didn't on Z3+/Z4 for now.
Maybe Sony will include it in future release.
https://github.com/AndroPlus-org/an...mmit/0edab0ae1a6ac8e298fdb4edee0323a5cd773dad
I did not read the SoC's specs, but the clock limitations may differ depending on the manufacturer, not on the SoC.
Thinking of the overheating issues it's possible Sony reduced the GPU clock to reduce heat dissipation.

Overclocking / Undervolting GPU and CPU?

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.

here is even a XDA link to another phone without any links to the app itself...

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
