[Q] Undervolted

I've undervolted my device and right now I have
100mhz - 825 mah
200mhz - 825 mah
500mhz - 800 mah
for some reason the 500mhz setting is stable and if I undervolt 100mhz/200mhz even more, I crash.
If I set my minimum processor power to 500mhz would I consume less batter than if I were to use 100mhz/200mhz?

Your phone spends most of its time in the lowest and highest cpu frequencies and just a small amount of time at the intermediate levels. Your undervolt for 500mhz probably isn't stable but it doesn't crash because it's only at that frequency for a very short amount of time. If you set the minimum to 500mhz at that voltage it will probably start playing up.

Abit offtopic but what the hell!
I was wondering if there's any risks involved with undervolting?
I don't meen the crashes and freeze ups, but rather more like if there's any risk
to really damage your phone from it?
I have and still do alot of OC in the computer world, and do know what overvolting can do. But i'm still curious about what uv can do to your system.

It's been my minimum even before posting this thread. I just started to wonder.
I've been on it for 10 hours now. I have 45% battery life left. Probably due to my 1700mhz being @ 1350mah right now.
I can assure you, it's VERY stable. It's so SMOOTH. Smoother than just having rocketrom and all that stuff. NO LAGS, NO SHUTDOWNS. ALL STABLE.
I can see better battery life, and CPU Spy says it used up 47% 1700mhz and 40% 500mhz. I think it's giving me better battery life.
It's evenly splitted up probably because I was using lulzactive governor.
but then again I didn't log my previous battery life without undervolting.
Some more insight would be nice.

There are alot of risks. Minor chance that you will cause hardware damage to your phone but I'm saying VERY minor. Just don't be stupid with voltages, like just suddenly overdropping the voltages. Your processor might die.
It's scary as hell, it crashes alot while testing and all that ****.
Feels good when you get it stable though.
TL;DR
Very slight chance to damage your hardware; only if you're very daring.
It should increase your battery life by atleast 20% if you reach the peak of your processors limit.

Bump, are there no other insights on this? Am I like, the only one who undervolted his/her note?

I want to run 1700mhz as permanent and also wanted to undervolt but i wasnt sure how much by and what the risks are. Reason being is my phone gets hot with heavy usage running at 1400mhz so didnt want to go to 1700. I'll watch this thread with interest

I'm running 500-1700mhz.
Indeed it does get hot at 1700mhz, when I'm playing games but I've only at most played for 4 hours straight.
For what reason would you want to run 1700mhz-1700mhz?

No sorry i meant running it at 1700 max, leaving it stock for the min. I just wanted to know how much i can safely undervolt 1700 by.

I actually have a question. I undervolted my note with SetCPU and I read that Tegrak Overclock Ultimate should be used as well together with SetCPU.
What does Tegrak Overclock do? GPU settings?
Would like to learn that part if anyone has any info.

I undervolted mine by about 100mah. I think I can tone it down by about 25mah more but I'm having a hard time getting it to stabilize.
1350 for my device is completely safe though.
Though, all processors are different. Yours could be better than mine and can withstand more UV-ing.
Goodluck!

It's basically the same with SetCPU aside from its voltages.
I do not know if it should be used with SetCPU with the note because from what I've researched. It's only a common practice with SGSII.

Tried setting 100 and 200 mhz to 825. Crashed my phone twice in one day using it, gonna revert back to 875

Many thanks!
I will just experiment then, i didnt want to do that and then cause hw damage. I'll let you know how my processor gets on

So does oc kill the phones life?

Simple question.
My freq now is 633 mhz..still will it shorten the life of my cpu???
Or higher freq and I mean not just for gaming,for everyday use.
Its mainly cuz of 360 launcher.
You need some higher freq to get the smooth look.
So???

Well, I've been using Overclock since the Day overclock came out..
And i have no damn problems .. CPU is still working Great!
And just to let ye know its clocked on 768 MHz ;D
Just overclock it Dude..
Your x8 will be Okay
But if u kept using it for long periods..
it might endanger Your CPU
Also be careful not to fall into a bootloop .. uncheck the Set on Boot option ..
check if it's working alright on 768 .. then check the Set on boot..
I have GDXv22 with [email protected] . .

Overclocking by 33MHz isn't dangerous, that's very mild.
In General - the more you overclock from the specified values (in case of the X8: 600MHz) the more heat you produce and the more you push the chip to the bleeding edge.
In short: Every integrated circuit has some headroom for overclock as the manufacturer specifies the clock rate at an safe value and not at the very bleeding edge where variances in the chip making process could lead to too high yields because they don't run stable with the clock frequency. In general you don't do your electronics a favor when pushing it too far. 700MHz+ will surely shorten the life span of your phone, how much would need to be seen as there's no real long-term experience.

Wow thanks guys.
You see after some thinkig it aint the cpu freq that is slow.
I set my low freq when in sleep on 245 so the phone is slow on waking up.
When you set it on high the phone will respond better!

like PC, when overclock it may reduce processor life

any clock reduces the life of your cpu. the higher the clock rate less life cpu

[REQ] mod for thermal throttling

Hi guys,
This thermal throttling is a problem especially when we play a game like Shadowgun deadzone or real racing 3. There is a mod to set a lower thermal throttling controll? For example to set up the limit temperature or the frequency?
P. S. I want this a locked bootloader.

You can flash a custom kernel and undervolt your CPU.
Other solutions:
- remove the protectioncase
-it's a xperia z -> water will help
-maybe a moded stock rom will help

This is your second thread in the wrong section. This is the development section. Please post your requests in the Q&A section.

I would suggest the force GPU mod, because then some tasks that the CPU is doing can be offloaded to the GPU, should result in less heat.

But for me the thermal problem is when i play a game...so if i Force the gpu i lose performance in game. I want someone like doomlord kernel for locked bootloader...to disable or get up the temperature of thermal throttling

Any kernel mod cannot happen on a locked bootloader, unfortunately. You can't do anything apart from lower your cpu frequency. That said, @1.2 Ghz the four cores give plenty performance. So try that. However, you have certain issues with downclocking not sticking with all four cores. This can be fixed only with a custom kernel for which you need a custom kernel and thus an unlocked bootloader.

thermal throttling
Nowadays, which is the best kernel to avoid thermal throttle? im thinking in hard gaming. Where can i found the best settings?

Any kernel that allows undervolting. Doomkernel, FXP, XzKernel, pretty much any custom kernel out there.
Best settings? That you have to try yourself. No two cpu are alike.

So the best way to avoid thermal throttling is undervolting? i thought must modify temperature limits in any way.

You don't wanna risk melting your device for too much heat, right? (It really does melt. Back cover is glued to the main frame).
Heavy undervolting takes some good 10º~15º off of the chipset. Enough to avoid throttling.

Have you tried heavy games one or two hours without thermal throttling?

avoiding thermal throttling?

When i play games like moderncombat5 i have 60fps but after a while the frames drop in some scenes where it didnt 3-5 minutes ago. When i check the cpu/gpu i can see that it throttles and causes these framedrops. But the phone doesnt get hot. Since it isnt possible to mess with thermal values at the moment. I wonder if there are some optimal cpu/gpu clocks where it will not throttle and performance will stay the same all time regardless of how much you stress the cpu/gpu. Because i'd rather have a underclocked cpu gpu than having thermal throttling while stressing the phone. On oneplus3 i didnt have this much thermal throttling playing mc5. I also feel the thermal throttling throttles way to early.
And yes i tried almost all kernels/roms out there it was a better experience on the op3
Thanks!

All CPUs have slight variations, some may be slightly more efficient than others of the same model. To get the best performance, you're going to have to underclock and test on your own phone bit by bit.

I dont remember. But it was hard to find. Anyways i found out that the cpu allways throttles down to little 1209 mhz and big 1440 mhz. When gpu is running on max clock. Will make further investigations now to find perfect cpu & gpu freq.

It seems regardless of what cpu profile / governor you use and regardless if the phone is charging or not. The cpu will allways throttle down to 1209 little and 1440 big. And the gpu also throttles but i can't monitor the exact values currently. This throttling even happens when gpu is running on min freq. And even when you set big or little cluster to min freq.
Im pretty sure the thermal throttling of the oneplus3 is broken. Because:
Thermal throttling should be decided by many factors. (General soc heat generated by gpu/cpu/and ram) also the system should be aware by the values and should handle it intelligently.)
It seems there is only one heatsensor used to throttle all at once and the throttling stops at 1209mhz little and 1440mhz big. If the temperature still rises the phone simply doesnt give a f*** why i think there isnt even a point of using this stock throttling method. And no its not accurate. And no its not usefull because, it throttles regardless what heat the phone has. Because it doesnt react to soc heat. It reacts to one of the components and throttles everything. Why it can't check the other temparatures aswell and throttle other components diffrently if even needed at all.
Issue: lets say little or big cluster is overheating because the cpu load is very high on it. (And no you wont see this throttling by simply running perf gov. It needs load/ working tasks on it, means you gotta play some heavy 3d games)
The thermal throttling just brakes down both clusters including the gpu. Was the big cluster or the gpu running cool? The thermal throttling doesn't give a f***. Could the loads/tasks been shared with or pushed to the big cluster. Thermal values dont care. Could some rly simple sort of hotplug turn the overhating little cluster off to let the big cluster do the rest before it rather throttles everything on the f... phone . -nope - Its annoying. Rly just try it out yourself. I really hope to see some improvements by oneplus. And no the phone is not bad at all. It's just some things are not optimized yet. Like touch latency which is worse than on galaxy s3 but i don't mind it just giving you an example so you can imagine how bad the thermal throttling must be.
Allways remember setting the cpu clock values so low that they dont throttle anymore doesnt mean gpu will throttle less often. All compenents will throttle without comparing other compents clock rate and heat.
My question: is the thermal throttling decided by the soc itself or are there different thermal throttling values on each phone brand using sd821?
And is it possible to port these values from lets say pixel phone?

I'm on cm13 and its kernel default is a bit lower than stock. I had the screen on full brightness and was charging the battery so temps above 100°. I played dead trigger 2 on highest settings on a level with lots of special effects and weapons with lots of splatter. Got throttled when the temp hit 103° everytime. I was running performance on cpu and gpu and i tested it without charging and still get throttled.

Im using laos 14.1 with latest ex kernel.
As is said thermal values are broken. Its not right to throttle down to same speed if charger is plugged as battery heat is higher and soc heat should be higher too. So i think it also throttles unnecesserily low without the charger being plugged.

Did any one find a solution to fix this?

Up up up
years of tired because of this ****ting throttling issue

Well do this at your own risk, go to system/vendor/bin and cut the file named "thermal-engine" to other directories in your sd card. This will completely disable thermal throttling. Perfect for gaming.?

Up up!!! This issues persists to me.. i even put my oneplus 3t in front of 8" fan for every gaming. Is there anyway to maintain the cpu frequency at higher rate during thermal throttling? I don't want to totally disable the thermal throttling... Seems unsafe... Enlighten me if you would

I think its time for gamer's to switch to a gaming oriented phone to avoid this thermal throttling and im looking forward to buy Black Shark which is Xiaomi backed gaming phone with custom rom (not miui) something different and that too is gaming focused hopefully it will be available globally soon ! :fingers-crossed:

There is no risk if you disable thermal throttling, the CPU will shut itself down if its temperature reaches 100°C

If i tilt my phone to the left for gaming, i will be burning my left thumb then.... even around cpu temp of 55.... My OnePlus 3T is gold in colour.. will it be better for heat dissipation if i change to midnight black?

LN2 + Copper pot. Should help.

There's nothing you can do about the throtting, OP3T throttles @60°C tbh in just 10 mins of game play it starts throtting
You have 2 options here
1. Either disable thermal engine as suggested by someone above ( it basically boils your device forget about gaming, temps touchs to 98°C if msm thermal is disabled and around 60 to 75°c it msm thermal is enabled it's seriously hot to touch and high chances of damaging internals
2. Underclock the big cluster to 1209MHz or 1286MHz I tested both, while gaming (2 hrs of pubg @ medium settings) temp's are around 53 to 55°c and never reached 60°c no throtting ( but you know what, games still lag or you will get low fps due to lack of power Lol I'm sorry that's true there nothing you can do about it try playing games in air conditioned room or just buy gaming Phone like Razer they have good heat dissipation, you should not forget the fact that our device is 2 years old. Tbh on a 2 year old phones even optimized games too use lot of processing power which lead more heat. More heat = throttle

N960F maximum frequency dose not scale over 1.79Ghz

Hello, my Note 9 does not go over 1.79Ghz, this happens also with the phone set for maximum performance. Using some cpu stress tools I can clearly see that the big cores set @1,79GHz like the little ones.
Also in 3cToolbox the usage for frequencies above 1.79Ghz is always 0.
Anyone is aware of this?
Thank You Very Much,
Mauro

im sure that this isnt common knowledge, so than k you for posting this, but im sure its the kernel causing the max clock speed. are you running stock firmware?

Yes It's the stock firmware. For example now over a total of 28min @1.79hz i Just have few seconds @2,7GHz and non at the intermediate levels.
Phone is again in Maximum Performance
