hey guys can i reduce the frequency of a core ?? will this destroy my phone ?
also checked my core and saw something incredible ! one core is minmum 384 and maximum 384 ! so this core is useless !! ???

If you have root yes, you can reduce the frequency with NoFrills for exemple.
And where did you saw min 384 max 384? :silly:
You can underclock with root any app that allow modifying CPU frequencies. To undervolt youll need custom kernel that allow such modifications.
So, i got curious and downloaded the "CPU z" application to have a look at my phones specs in detail. I found that my processor was the "4x ARM Cortex A7 @1.19Ghz". however the advertised processor is the "1.20GHz Qualcomm Snapdragon 400" now, is this just a pre-manufacturing model name and I'm just being stupid or is something fishy going on here?
Also i find it odd that the actual processor in my device is clocked at 1.19 when i in fact was under the idea that it's a 1.20 clock speed. I'm sure it wouldn't make that much difference but still seem odd?
could someone put my mind at rest and tell me that I'm just being an amateur and to go back into my android noobie cave or can someone confirm that in fact something fishy is going down.
thanks!

So, I went on a "boredom rampage" and I've read an article about a guy overclocking his 865 GPU to 865 MHz and reaching Adreno 660-levels of performance and I decided to give it a try and it was awesome.
Problem is, I'm too much of a thinkerer and I pushed the GPU as much as I could. I ended up on 2000 MHz with "TURBO" voltage profile and it's rock solid even on 2100 MHz with the same profile but KonaBess gives me an error if I try to edit the GPU tables after I booted at 2100 MHz.
I even edited the clock profiles to make it smoother, starting from 305 MHz to 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 with the right voltages.
Now, the battery and SoC temperatures are the same, the battery drain is basically the same, some other fellow modders with the same device (Mi 10T Pro 5G 8/256 with Pixel Experience Plus ROM) didn't manage to hit the same clocks, crashing even with 1000 or 1200 MHz, with my file from the KonaBess app.
So, have I been extremely lucky with the silicon lottery or it's just an illusion?
Please ask if you need ANY benchmark or proof. I've been monitoring the GPU clock with Franco Kernel Manager Live Monitoring and the clock is solid at 2000 MHz and the 3D performance has at first jumped and then slowly climbed, especially on 3DMark Wild Life Extreme. Wild Life Extreme Stress Test is stable the temperatures are fine.
Do you guys have any questions/suggestions/requests?
Edit: Here are some 3DMark runs, both Wild Life and Wild Life Extreme at stock and 2 GHz. I use Greenify, my storage is 94% full and all my processes in the background take up 4 GB of RAM and I didn't touch the bus for the various steppings for the clocks, so I believe that if heavily tuned, this could make a difference.
post before and after pictures of 3dmark.

I have the history of all the bench on 3DMark, because I downloaded it just for this. Would that be ok?
it seems fishy, a 1ghz+ oc would increase your fps by more than that.

It doesn't have the biggest of bumps from 900 MHz to 1 GHz or 2 GHz, but still, is capable of doing it and rock solid too.

i don't think your gpu is actually running at 2ghz while you are running a benchmark. going from stock to 2ghz would at least have to give you an extra 20-30 fps in Wild Life.

Not necessarily. The GPU IS running at 2 GHz but I think that the problem might be some diminishing returns where the clock doesn't mean anything after a certain point.
Are you try locking the freq on 2ghz in Kernel maneger ? Set min and max to 2gzhz with performance governor .

I've made various frequency steps. 400, 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 MHz. But if I change the governor, after I reboot, it will be msm-adreno-tz again. Max frequency is still 2000 MHz and minimum 400 MHz.
Yes after reboot is resets like on every phone you have to check apply on boot and select min 2000GHZ and max 2000ghz GPu freq in tap in FKM and set gov to performance and do benchmark like 3dmark wild life . Like that. And in Smart pack Kernel manager free app is GPU throttle turn that off.
Check box apply on boot and after boot will be apply.
And that you can show improvements of OC

Thanks What is temperature ? Do you game with that or this just experiment ?
Temperatures are roughly the same. I do game with that. On normal games, frequency stays at 400 MHz, but on really heavy games like Genshin Impact, completely maxed out, depending on the scene, the GPU goes to 1.6 or 1.8 GHz and rarely at 2 GHz during some heavy cutscenes. 3DMark keeps it at 2 GHz all the time.

Hello, excuse my ignorance, but I want to learn what konabess is, it's an app or a magisk module, I also have the xiaomi mi 10t pro with DotOs rum android 11 and then I want to play more fluently, could you help me
konabess app is software you can overclock GPU and undervolt.
You need root and that it.
https://github.com/libxzr/KonaBess
Here tutorial but it old I need make new one because there isn't good one tutorial about it.
This doesn't make any sense. Why would Qualcomm leave so much on the table ?
Hello there, Ive decided to “overclock” my Snapdragon 888 iGPU. Im using the GPU pretty heavily with emulators like the new AetherSX2 and wanted to give this a try. My problem was the lack of performance with Lineage OS, Kernel seems to clock lower on default. So, this was the best solution for me.
If your Mi11 or other device with SD888 (other chips are supported too) is rooted, you could test this too and could share your results . I will be more focused on my results, here is a good guide with good values to start (table: OC#1 XDA), at the bottom of this thread: https://forum.xda-developers.com/t/...s-gpu-now-with-root-and-konabess-app.4275089/
What you need: https://github.com/libxzr/KonaBess, this apk allows to give your voltage value (fixed) a frequency. Set the frequency higher with const. voltage = overclocking, set voltage lower with const. frequency = undervolting. You should (please!) make a backup of your vendor_boot.img and save it on your PC, to reset to the default values if your phone isnt stable.
If my theory is true with lower voltage/lower frequency in this kernel, I basically have an undervolted iGPU with nearly the same performance of an SD888. After 20min stress testing in 3D mark or combined with Antutu there is still no thermal throttling. Somehow there should be a reason for the better battery life. So, a higher clockspeeds (nearly stock) with the lower discrete voltages should give a performance boost without sacrificing battery life.
Please be aware that my values could only work for AOSP or LineageOS 18.1 20211105, you should try it with little steps:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
My results Antutu and 3d Mark:
It seems that the temperature and the stability is much better, than the stock MIUI Version, as you can see in this video
. Its a comparison between Mi11, S21 Ultra and Mate40Pro with 3D Mark Wild Life Stress Test. Peak performance on the Mi11 is about 5 percent higher, but at the end more than 25% lower due to the thermal throttling. Geekbench shows nearly no difference, it seems that it is more CPU-biased . Would love to hear the reason of all of this, please feel free to share your thoughts. Sorry for grammar or spelling mistakes, English is not my native language.
Hi
I have Xiaomi Mi 10T with Snapdragon 865 with Adreno 650 GPU and 8 GB LPDDR5 RAM and I used Konabess app to Overclock GPU to beat ROG Phone 5 in Vulkan performance.
I used This two tables to overclock to 905-940Mhz.
Adreno 660 is just overclock on Adreno 650 from Snapdragon 865.
If you want more performance look for CAF ROMs like I did.
I'm using Xdroid ROM with is CAF ROM.( CAF stands for the CodeAurora Forum. It is like the name says, an online forum (just like XDA, except, the forum is more for OS developers than flashmaniacs) where Qualcomm releases source codes and patches for their CPUs. Code Aurora is a kind of an initiative in which brands can release the open-source codes for SoCs(CPUs) for future software development. )
First few technical staff.
1000 Gigaflops = 1 Teraflops/TFLOPS
Adreno 650 on 587 MHz has 1202 Gigaflops
Adreno 660 on 840 MHz has 1702 Gigaflops
Adreno 650 on 905 MHz has 1853 Gigaflops
Adreno 650 on 940 MHz has 1925 Gigaflops
You overclock Adreno 660 to 855 MHz so you have 1751 Gigaflops.
You can calculate this very easily
Shading units 512 * freq 0.905 * 4 = 1853 Gigaflops = 1.8 TFLOPS
Compere to home consoles last gen
PS4 has 1.84 TFLOPS
Xbox One S 1.4 TFLOPS
Nintendo switch 1TFLOPS docked and undock around 500 Teraflops.
I overclock my Adreno 650 to 940Mhz giving me performance of SD888 with new drivers OpenGL 604 ( I link below if you want try on SD888 )
Ybf
Performance is incredible just from driver it self. Stock freq 587 MHz gives 4230-4150 score in Wild life just like SD870.
I used 940MHz and 905MHz on TURBO_L0 Voltage.
You can click on any images to get closer view.
Here is AnTuTu before overclock on stock freq 587MHz and 3Dmark Wild life
Now here we go to 940Mhz overclock with GPU.
AnTuTu Score beats Mi 11 and few SD 888 smartphones.
Here is Wild life and Wild life stress test.
Here are bonus 3DMark Sling **** Extreme Unlimited and Geekbench 5 Vulkan Compute test
And here are temp of Red Magic 6 series phones.
And here is temperature of all big SD888 phones to compere.
Here is test which show how many Watts GPU uses.
Overclock to 905-940Mhz with new drivers v604 use 7W on of power without idle screen 0.8W compere to SD888 which is much higher around 1.5W
Gfx Benchmark Manhattan 3.1 off screen 112-115fps with 7W
SD888 GfxBench Manhattan 3.1 off screen 117 fps with 8W-8.5W of power.
Running Genshin Impact on 60fps highest gets 7.2W of power with 58fps almost lock and SD888 uses 8.5-11W to run this game.

Thank you very much, gives much insight. Also it shows the efficiency of the 888, which is actually really bad for a newer gen cpu . Hopefully the competition with Mediateks Dimensity will push the development. 8 gen 1 seems like a disappointment, it probably will throttle like hell.

Root is supported on any device of Xiaomi just unlock bootloader via Mi Unclock tool and get boot.img of your Rom you can do that even of MIUI without PC or find MIUI version for phone in internet.
When you update phone or you can select to install update again in right corner option you will get zip or your Rom just use rar and extract boot.img and repack it via Magisk app with unlock bootloader you can boot to fastboot and with adb debugging via adb flash boot.img from Magisk and you are rooted.

...hum i know that, i'm an active / old Xda users, and root my device from my first Android device in 2010.
When i talk about root it's for rom dev.
I mean Mediatek is not supported by dev... not more, not less. Mediatek is a pity for customers search waiting Custom MIUI or AOSP rom because any dev purpose build on this models.
And i think it's more important for users to have a CPU with a good compatibility with apps/dev/emulation instead choose a Mediatek for a "maybe" better overclock.

Im sorry, but I didn't make a backup of the custom values. It is easier to copy paste the values and probably better to tweak in little steps.
Can you undervolt though leave CPU frequency the same? With less volts though same speeds you should see better performance sure to less thermal throttling. Assuming it can run stable

Yes, you give your core other values. I basically give higher clocks at the same voltage values. But I've tested also lower voltage values at the same clocks and it works. But I don't know how much a increment is in volt. With LineageOS my phone runs already cooler, so I didn't feel the need to undervolt it.
I have successfully modified the default highest clock 840MHz down to 825 with one step down in voltage level (TURBO_L1 to TURBO_L0) and added extra lower clock 251MHz at the same voltage of the default lowest clock LOW_SVS
been using it for few days on pixel experience 12.1 with no issues, just a subtle decrease in gpu score in benchmark..but battery wise I didn't notice any difference
Now if anyone can share a way to edit the CPU voltage without applying custom kernels

As far as I know 840MHz @Turbo_L1 is the default max clock of adreno 660 which also was the default value in konabess
I only undervolted it once by going one step down in voltage because frankly I don't want the hassle of trial and error..but if you are saying you could boot with even lower voltage with nearly same performance I might give it a try

Not could it works perfectly tested on few hundred devices.
Of course your silicone lottery can be different but -10MHz is worth it to use with NOM aka 830MHz and lower.
