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
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

I have a question about the 3D's dual core that I'd like more clarification on the vague answers I'm getting by searching this site and google. So I've read that the core is asynchronous so basically meaning the second core doesn't do much work unless needed as others like the tegra 2 and exynos have both cores running or something similar to that, and that this is affecting the benchmark scores. I also read that one would basically double the score of the 3D to get a more accurate reading. Can anyone confirm or further explain this?
Yes, asynchronous is when something operates on another thread whereas the main thread is still available for operating. This allows for better performance in terms of managing tasks. Now just because it doesn't score high on a benchmark, it doesn't mean it is going to perform. Also this allows for better performance for the battery.
I haven't slept for the past 12 hours so if this doesn't help you, just let me know and I will fully elaborate on how the processor will operate on the phone. Now time for bed :'(
In short, asynchronous operation means that a process operates independently of other processes.
Think of transferring a file. A separate thread will utilized for doing so. You will then be able to do background things such as playing with the UI, such as Sense since you will be using the main thread. If anything were to happen to the transferring file (such as it failing), you will be able to cancel it because it is independent on another thread.
I hope this makes sense man, kind of tired. Now I'm really going to bed.

To be more specific by asynchronous they mean that each core can run at different clock speeds. Core 1 could be at 1.2 ghz while core 2 is at 200 mhz. Most multi core processors are synchronous meaning all the cores are running at the same speed.

I was also very curious to learn a little more about the async cores and how it differes from a standard "Always-On" dual core arctechiure.
Thh first page/video I found talks about the SnapDragon core specifically.
http://socialtimes.com/dual-core-snapdragon-processor-qualcomm-soundbytes_b49063
From what I've gathered, it comes down to using the second core and thus more power, only when needed. Minimizing voltage and heat to preserve battery life.
The following video goes into similar and slightly deeper detail about the processor specifically found in the EVO 3D. The demo is running a processor benchmark with a visual real time usage of the two cores. You can briefly see how the two cores are trading off the workload between each other. It was previously mentioned somewhere else on this forum, but I believe by seperating a workload between two chips, the chip will use less power across the two chips vs putting the same workload on a sinlge chip. I'm sure someone else will chime in with some additional detail. Also, after seeing some of these demos, I'm inclined to think that the processor found in the EVO 3D is actually stable at 1.5 but has been underclocked to 1.2 to conserve battery. Only time spent within our hands will tell.
Another demo of the MSM8660 and Adreno 220 GPU found in the EVO 3D. Its crazy to think we've come this far for mobile phone technology.
What occurred to me is how complex Community ROMs for such a device may become with the addition of Video Drivers that may continue to be upgraded and improved (think early Video Card tweaks for PC). Wondering how easy/difficult it will be to get our hands on them, possibly through extraction of updated stock ROMs.
EDIT: As far as benchmarks are concerned, I blame the inability of today's bench marking apps to consider async cores or properly utilize them during testing to factor the over all score. Because the current tests are most likely to be spread across cores which favors efficiency, the scores are going to be much lower than what the true power and performance of the chips can produce. I think of it as putting a horsepower governor on a Ferrari.
thanks for the explanation everyone
The best demonstration is in the first video posted, notice when Charbax looks at the monitor. There on the top right are the frequencies of the two cores, and you'll notice the both of them jumping around a lot, independent of the other. Using the cores "on-demand" only when needed ends up saving a lot of battery power, but doesn't give you any performance loss.

Actually I was thinking that not just the battery savings but there could be a performance gain. Think of this if the manufacturer knows they only have to clock one core up to speed when needed they can be more aggressive about their timings and have the core clock up faster than a normal dual core would since they know they don't have to clock up both processors when only one needs the full speed.
I wonder if the drop to 1.2 GHz also serves to keep heat under control. It might not just be battery savings, maybe the small case of a phone doesn't allow for proper cooling to hit 1.5 safely.
I'd love to see some confirmation that the asynchronous nature of this chipset is what's responsible for the seemingly lackluster benchmarking.

The "horrible" benchmark scores are simply due to the tests inability to consider async core performance. Wait till the tests are able to take this into consideration.

I went through all of your links, I didn't see anything that confirms that the benches are somehow affected by the asynchronous nature of the chipset. It's not that I don't believe you, I actually had that same theory when the benches first came out. I just don't have any proof or explanation of it. Do you have a link that provides more solid evidence that this is the case?
NVIDIA actually tells a different story (of course)
http://www.intomobile.com/2011/03/24/nvidia-tegra-2-outperforms-qualcomm-dualcore-1015/
AnandTech's article does explain some of the differences
http://www.anandtech.com/show/4144/...gra-2-review-the-first-dual-core-smartphone/4
It appears that Snapdragon (Scorpion) will excel in some tasks (FPU, non-bandwith constrained applications), but will fall short in others .
I'm pretty sure none of the benchmark apps have even been updated past the release of the sensation so yeah....How could they update the app to use the asynchronus processors the if the only phones to use them have only recently been released.

Hmm...
If a program such as Smart bench (which takes advantage of dual cores) is stressing both cores to 1.2ghz then regardless of if both cores are active or not the bench will be accurate.
I would rather NOT have asyncronus cores as there would be lag during frequency changes...
Ex:
2 cores running at 500mhz vs 1 core @ 1ghz and other not active.
The 2 cores will produce less heat and use less energy...

There dual, it would be better for them to run asynchronous. Not only that, but it is a phone so there will be no lag between frequency changing. 2 Cores running at 500mhz will perform better than 1 core at 1ghz.

This is something that the hardware needs to be capable of. Software can only do so much. As far as I've seen Tegra isn't capable of it.
I read the anandtech article and I came with conclusion that everyday task you might not see the difference between the two and while tegra2 might bench higher. The main thing people dont talk about is the GPU. Adreno 220 is a powerhouse GPU, it will probably stand strong when tegra 3 comes out.

What?!?
Andreno 220 is a horrible GPU. AT BEST it is equal to the GPU in the Original SGS.
The reason benches are so different is because Qualcomm has made NO improvements in the CPU. Desire HD CPU is the same as Sensations. While... SGS2 + Tegra have IMPROVED CPUs.
Arm 7 vs arm 9?

Because it's supposed to run at 1.2Ghz.
If every SGS2 was able to run at 1.4Ghz without any issue I guess Samsung would have set them at 1.4Ghz by default (since battery life is obviously the least of their concerns ^^). When CPUs are produced, there's always variations in quality. what usually happens on x86 CPUs is that they're tested, sorted according to their max stable frequency, and then sold under different names and at different prices. For Exynos my guess is that any CPU that fails to pass the 1.2Ghz bar is just ditched, and they keep the others, some of which will work at 1.4Ghz, whereas some won't.
Now if you want to gain more stability, you can always try to increase the voltage, it usually gets more stable as voltage increases, but it also gets hotter (which can cause it to crash, or may even permanently damage the processor).

At 1.4ghz the phone will also get hotter and it decreases the lifetime if you run 24/7 at 1.4ghz
Ok.. I know about the x86 cpu's.. But didn't think it was the same in ARM cpu's-
But I see ALOT SGS2 that runs 1800mhz..
I guess that I just have one of the not so OC lilkes...
Overclocking won't always work for everyone at same levels.
I've also seen evidence to suggest that OCing significantly reduces the life of the SGS2. Nobnut had his phone vastly overheating even on stock speeds, and constantly rebooting... He overclocked. A number of others reported similar.
Overclocking is not simple and it is not that you just click on 1400/1500 MHz and you are Overclocked. A lot of things matter here. When we overclock in our Desktops then we have to test it very thoroughly, setting up the right VCore, Bus voltage, Multiplier, checking the stability and temperature etc. etc. Tegrak OC is a nice and simple software to use, but it can't be perfect when you can't set all the settings manually other that just higher the clock rate. Personally I'd always stay with stock speed as incorrect OC could harm my CPU and GPU.
Regards.
If you know anything about overclocking then you'll understand that there are a variety of factors that affect the overclocking of a system. The overclock headroom you get from a processor varies, add to that the variables in component tolerance in the circuit board and you have a huge variety of factors that can limit the maximum frequency that you can overclock your system to.
I'll give you an example using my computers. Click on the images below:
Both processor overclock similarly on using the same components and that was the maximum I could get out of them. Now when I bought an EVGA X58 Classified motherboard and overclocked the Xeon W3520 I got it up to 4704 MHz with less vCore and less CPU VTT. All of this was done with aircooling.
My point is that not all systems will overclock the same even though they share the same model components.
Is there a way to overclock the Adreno 220 GPU that I consider to be laying dormant as of now inside the HTC EVO 3D and Sensation? I read some of post the the Desire HD section that mentioned they were jealous that the sensation already got a GPU overclock but they didn't provide a link and my searches have come up with nothing. If I could, I would post a link, but I didn't find anything. If anyone could provide a hit of clarity or insight into this topic, please do.

From every ROM I've ever seen they never say the GPU has been overclocked. That requires Kernel modified.
Everything I've seen states "GPU Tweaks" which I believe only means they've tweaked the amount of memory allocated or the MPAA settings. Which is just a simple prop edit.

I am looking to buy a new phone,i don't like iphones,my current one is a Vibrant,so i am thinking about the Galaxys 2 from T mobile.
But since it use a 1.5 qualcoom cpu and andreno 220 GPU i don't know,since i don't know that GPU well,i don't know if it is weak or not,i love the Vibrant GPU it was quite ahead of anything until the Tegra 2 arrived.
Let's summarize for a second here:
The Qualcomm CPU is built for 1.5GHz, but underclocked to 1.2 GHz to save on battery and heat.
The Adreno 220 is underclocked to save on battery and heat.
The Adreno 220 is anywhere from ~5-50% faster than the Tegra 2 dependent on the benchmark/utility/application
The Adreno 220 (even underclocked) will perform so well that any mobile game out today will run without any perceived negative performance that is humanly detectible.
The Adreno 220 performs so well that the above will still be true for any mobile game that comes out between now and the time you get your next device
With the above facts true, there is effectively zero reason to currently want or need to overclock the GPU. What reason did you have to want to? Just to say you did? The way I see it the perceived benefits can't possibly outweigh the risks. I'm not sure (without doing the research) but I believe the Adreno 220 is still the best performing GPU on the market.

Judging from: http://forum.xda-developers.com/showthread.php?p=39719050#post39719050 It would seem the GPU can clock at 100Mhz, 160MHz, 266MHz, 400MHz, 450MHz, and 533MHz (not sure if this is custom behavior or stock).
and custom kernels have shown we EASILY (like on stock volts easy) can overclock from 533MHz up to 720MHz. This GPU can become a real powerhouse as it gets clocked higher, and I am thinking that if we wanted to overvolt it enough we could probably even have it running at 1GHz.
As for vram, it doesnt have any. VRAM is shared with system RAM and it uses something like 1GB of system memory in reserve for the GPU on this tablet. People theorize that it dedicates so much because of our huge resolution, and that lesser devices would not need to hoard as much of the memory.

That'd be insane lol... my desktop GPU (Radeon HD 7850) is factory OC'd and isn't even 1GHz

Ya, but you cant compare MHz between architectures very easily. Your desktop card has WAY more power than this tablet grade GPU. Makes me wish I could get my hands on a Mali T-628 though, with the same OC we have now on that thing I could see it blowing away anything else on the market or coming out soon.
Unfortunately Ktoonsez said it looks like our frequency table is maxed out on the GPU, so I dont know if we will be able to OC higher despite if the GPU is capable of it or not.
Gpu clockspeed isn't always THAT important just look at the GTX Titan, it's only 700-800Mhz yet it's the world's fastest gpu.

At the risk of turning this into a Desktop GPU thread; I believe AMD"s 7990 takes the spot at world's fastest GPU currently. Almost certain it slaughters the Titan at compute, and pretty sure it beats Titan in most gaming benchmarks. In terms of frame latency though, AMD might be lacking in that department, but not for long :good:
I do agree though clock speed isn't that important in most cases. Almost got a Radeon HD 7770 GHz Edition card just because of the 1GHz core clock, but the 7850 I got still outperforms it (to be fair though, it's only 50Mhz lower than 1GHz).
Regardless, with the Nexus 10's resolution, pretty sure we need a nice balance of memory frequency and GPU clock speed. GPU can be as fast as it wants, but it won't help much if the memory bandwidth is being choked :/

Thats why I said the T-628 could be the fastest if we can OC it the same. Our current GPU has "four cores" and at 720MHz GPU speed we can push 2560x1440 pixels at 58 frames per second average on the Unreal 3 engine. The T-628 is the same as what we have but twice as many cores, so twice as many computing resources. Sure there are other things coming out that are pretty fast, but think of what 2x the power of our current GPU could do At this point though espionage724 would be right, we would probably see memory bottleneck so we would need to step up from DDR-1600 to DDR-2133. Still, testing I have done shows we are just barely starting to hit a memory bottleneck with our GPU @ 720MHz, and if we OC the memory up to DDR-1728 we have lots of extra bandwidth to spare. So changing the memory up to 2133 would alleviate any sort of bottleneck that would ever show up in that area even with twice as many GPU cores.
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.
