[Q] CPu and Quadrant

Hello!
I really dont know whats normal for a X8 in Quadrant but my X8 are sometimes lying around 682 but I've also been on 720-750 a couple of times. How can those numbers be so different?
Phone info:
Used since: 2010-12-24
ROM: Rachts CM7 Rc4 2.3.3 (Latest update)
CPU: Overclocked to 710 MHz
I can't post my question in the Development thread about overclocking because I don't have 10 posts but I've now overclocked it just to 710 (Normal with that "program") but how can i try to go up to 730 Mhz now?
Thanks
RoseN

Added some more info to first post...

The number show you the speed of your phone the time you test is. This means that if the next time you make the test your phone search for network or you play with your screen or you download something or you have many programmes running then the result of your speed will be lower.

What quadrant does is called benchmarking. Basically, it measures your phones performance in several aspects and at the end you could compare it to some of the big guns in android.
It analyses the CPU, 2D and 3D performance, and memory among others. The higher you score, the better our phone's performance has been rated.
Some of the things that affect your rating are: the number of apps that are running, overclock or clocking of CPU, and available memory.
You phone could misbehave from time to time so the results may vary...

Under clocking /changing CPU speed

Hey
I was wondering if anyone was playing around with changing CPU speed. I noticed that 6P may not overheat but that's only because it throttles. I was wondering if shuting down two of its main cores would enable the other two run faster thus achieving better overall performance.
I was just wondering if apps actually use four cores? Or is it better to have two, faster ones.

You can use whatever combo you like really, but you'll need an editor [like kernel auditor] and root to do so.

I know I was just wondering if anyone actually did this and had any results to share. At the moment I'm almost convinced to do root so when I eventually do it I will try it out and share with the community.

I mean there's no real disadvantage, somewhere. You just cap your max performance, within reason.
Some people go with a hexacore setup and disable 2 of A57 cores and runs just fine...all about CPU task load.

Overclocking possible?

I want to raise question is it possible to overclock the CPU, or GPU or memory speed. We all know that ze550kl / z00l performance with msm8916. Is almost in the limit to run apps and games, wanted to know if possible or not, and if there is any development has this respect. I like the device and it is great but it is clear that it is getting weak in the matter of hardware, if someone can work in this respect to give a breath / power to our device

i don't think so , if its possible to overclock the processor to its frequency,
you can costumize it too max frequency of it or to lower , as u need
But if is then i would love like to know too

I am already extracting the maximum, from him that I can of him, already put using ex kernel, with governor ordenad, frequency of 200mhz @ 12000mhz, and simple GPU ordered frequency of 200mhz to 400mhz, active zram of 512mb, and entropy of 128/256, then Of course, here with standard frequency of the paddle extracting nothing more than that, the problem and that we have a large bottleneck in memory lpddr3 of 533mhz, that opera and 32bit, there is a single channel giving bandwidth of 4.2gb / s that It has to be split between CPU and GPU. What is clearly one of the pro soc power limiter, I do not know much about the arm architecture, but I can not do over clock in lpddr3 memory, since I did not see any software or tutoring Citing this. Although this would be a solution, if you do over clock in the CPU or ns GPU will force the clock controller up what will increase the memory performance consequently, something else, not good will lock the clock at maximum in 1200mhz and GPU at 400mhz, as there will be a large power consumption and the performance will be limited by the cords of the tempering control and the low frequency of the RAM, # excuse me to have been so far more enthusiastic about hardware,

even with my old htc explorer i could increase cpu clocsk from 600mhz to 900mhz why we cant do it on zenfone 2 just we need good developer and kernel

it's up to the hardware
If you look at the specs from qualcom it has a max speed and not every device is possible to reach the max, but if you have the proper kernel you can reach that speed and "overclock"

CPU Throttling - warranty?

Hello !
After long weeks of searching the answer and solution to my problem, I am exhausted. So I would like to ask the biggest Android community for help
Well, I know it's not new, but I have problem with my S7 Edge (Exynos) performance
I experience FPS drops in almost every game I play. As for games it's not that irritating, but recently I have bought Gear VR and while having this thing so close to your eyes, you see every frame skipping.
Apps for checking the CPU throttling shows that after 5-10 minutes the 4 bigger cores slow down to about 50% of their full speed. It leads to ~30% performance slow down.
I tried every solution that doesn't require root access and warranty void. For example: disabling certain packages and services (Game Launcher, Game optimization service); different settings in Game Tuner; performance mode; factory reset etc. Nothing works.
Does this kind of problems can be repaired on warranty? I know that in order to fix this you can change kernel setting, cpu governor etc but ofc they don't do that in Samsung Service Center. Is it possible for them to replace the main board and cpu with Snapdragon one?
I would not like to root my device because I didn't want to lose my 3 years warranty and I am using a lot of applications that may not work with a root.
Thank you in advance for all your replies

Did you try the game performance mode? As the "performance mode" is just screen resolution and brightness. The game mode is the real performance mode where the temps throttling is relaxed and higher clock speeds allowed(you can also edit the profile to set the resolution manually to wqhd). You can also try to set the resolution to full hd and see how it goes (tho for VR it won't be cool, but for the test it won't hurt). Also if the phone is new, it will need atleast 10 days to settle and become faster, smoother, better. Apply updates if they are pending too.
Otherwise you can't do much without root, but even then you are limited to what you can achieve so be careful + samsung have a fuse into the chip that burns out when you root the phone, it's not possible to hide the intervention and they can deny warranty for that reason (and often do so).

Yes, I've tried "game mode" but there is no difference. Changing resolution to Full HD helps for a while, but the Gear VR software doesn't work properly on anything other than WQHD. It just doesn't scale properly and you are unable to see whole content.
I'm just wondering whether every S7 Edge has problems like mine. I understand throttling after 20-30 minutes of intensive gameplay, but ~40% slow down after 3-5 minutes seems strange, especially because phone doesn't even get warm.

Hard to tell, got the phone, but no vr... :/
Otherwise I don't have problems with gaming, the game mode smooths a little the already fluid gaming(but then again, the game I play mostly is vainglory and that game runs great on htc m8 that is almost 4 years old). You are talking about some more massive performance drop. Many phones start to throttle early and throttle hard, samsung is one of them for sure (they want the phone cold).
@hamdir can you lend a hand on that one? You are tons more experience with VR than me.

Well, there is an app called CPU Throttling Test on Google Play. I would be really thankful if you give me information how your phone behave in this app. Mine throttles hard after 3-8 minutes. Clock speed of the better cores goes down to about 1.6GHz each. Sometimes even below 1.5GHz.

From a cold phone, 1.9GHz almost right away(I guess the highest freq is only for burst load, like app launching) and kept for 8 minutes then drop to 1.57GHz on the big cores. So I think it's in line with your result.

Yeah, that would be it. Thank you for your time. So it seems to be normal, I hope I'll get used to it somehow
I also wrote an email to Oculus, maybe they heard sth about this issue and know a fix for frames skipping.

The notorious feature known as DVFS is the likely culprit. Some forum members suggest it throttles the GPU and CPU to improve benchmark results or otherwise to protect the device. I've noticed it can lock-up and end up overheating the device but that's just an anecdote.
You can try forcing the app to run at a lower resolution which Samsung's Game Tuner does for some games, or find other solutions for unrooted devices like capping CPU frequency for a smoother experience.

Almost all the phones are tweaked to use max freq only on single core load and app startup (burst). If their power management detect heavy load on all cores, it will automatically scale down to lower freq state to prevent heat building up fast. In reality in our case this is 1.87GHz for all big cores + the small ones (higher if only the big cluster is used, leaving the small cores off). The first actual thermal throttling level is 1.56-1.57GHz at around 8 minutes mark. Games would take a lot longer and in my observation as the phone is big and none will use 8 cores at the same time - there will be no throttling, just power management and stable fps. His case is different tho, VR is really a heavy one on the CPU.
As for DVFS (and extended to samsung power management, every manufacturer has it's own management) - it's there for a reason, to use your phone without major slowdowns due to heat and to be cold in touch, i.e. better for use. You can always change the behaviour via custom kernel, but you can't get more performance without heating the phone to the point of hardware throttling or uncomfortable to hold. Actually as you said - the right way if modify is to cap to lower freq and try to command the phone to keep them. This would still lead to a lot of heat, but will take some time to build up (and it will look smoother, tho with lower fps). OC is pointless for speed gains, will work only for burst loads. UV is not effective too as nowdays the SOC's are heavily binned for optimal settings from the factory.

How Can I Get Better Gaming Experience in A310F?

I'm using stock nougat rom now. It's stable but i got many lag in games. So i tried lineage os 14.1 and 15.1. They were good in Pubg Mobile first ( better fps and without lag) but after my phone overheated ( really heated very much) i couldn't press screen with soft press. I needed press hard for detect it.
So I'm asking, what can i do for lagfree, smoothest gaming experience? I would really appreciate if you can help.

From this information, it is a hardware limitation. That specific game is GPU intensive and appears to be multithreaded well on the CPU. CPU/GPU are a bit like a motor, running at various speeds, 'weights it is carrying', and the power required to maintain that speed. High power = high heat. If it gets too hot it usually reduces the speed. On the stock ROM (Touchwiz), as far as I know, the customfrequencymanagerservice limits CPU and GPU speed for games, based on chipset temperature(?) for non-games, and bidirectional thermal throttling(?) for devices with the HW performance setting. The other limit's by kernel, somewhere around 86c. Here's what could be done.
Limit speed of the CPU/GPU to where the heat and the FPS are balanced. The CPU underclock is easily found(alternatively /sys/power/cpufreq_max_limit), GPU underclock is at /sys/class/misc/mali0/device/dvfs_max_lock. If the change is suddenly undone, set permissions to 644. By setting those permissions, the customfrequencymanagerservice can't write to the file, and the device will get hot if the clock is too high.
Set graphics (there are graphics settings, easily accessible in the international version, for the other version, there are translations) to smooth. Less heat, more fps, at the cost of resolution & various kinds of shadows)
Set Frame Rate to low, less heat at the cost of FPS.
