I am new to android phones. And i have no experience about overclock.
Will my cpu easily break down due to keep overclocking?..
Honestly, i seldom change my cell phone model, i want my defy can stay a life at least 1.5yr.
i think overclocking can't really damage your phone, voltage can. so i suggest you keep the voltage around [email protected] (default is [email protected], so this should be fine), and if the phone doesn't hang or reboot, you're good to go but you could try lowering vsels, you know, the lower the voltage, the lower the power consumption, the heat and the chance to fry your cpu but i'm not sure!
Yep, 1 GHz is safe, I'm using [email protected] as well, and the CPU is capable to run easily at [email protected] continuously. The leaked Gingerbread ROM from Motorola uses 1GHz as well, so don't worry, you just have to find the safe vsel settings.
thanks for replying, i m currently using 1GHz @ 58 .. Everything is alright
Should I make the voltage as low as possible?
yeah, just to lower the power consumption and temperature, but it isn't necessary.
Can you share your voltage setting please..?
I do the stability test and it gets successful run for 5min then this means the setting is okay?
i don't overclock, just undervolt, here are my settings (with setvsel):
800MHz - 45vsel
600MHz - 30vsel
300MHz - 18vsel
up_threshold: 90%
actually if you wanna make absolutely sure your device is stable, you should run it like for an hour. but if it runs for 5 minutes without error that's quite okay, you shouldn't have problems with those settings
Thanks so much, i m trying to lower my voltage setting.
Besides, i want to ask about the battery temperature, what is the maximum temperature before getting damage to the cell? I usually goes up to 37~39 degree celsius.. is it normal?
mine is usually around 29-32 °C, but i have it undervolted, so idk. but 37-39 seems a bit high, that means the cpu temp is way over 40 degrees, you should check it out!
EDIT: tried stress testing for 20 minutes with [email protected], it went up to 35°C, so you should definitely find out what's wrong with your device!
I actually underclocked to 600MHz, since I couldn't see a big difference even at 1200MHz in normal usage. A Pentium3 at 4Ghz will still not perform as well as a slower clocked new CPU for example, CPU design is more important - what instructions it supports.
Battery life is more imprtant to me and heat is very bad for Li-ion batteries too.
Also I found changing the CPU governor to "interactive" made a difference in GUI responsiveness and I have had less stuttering.

so, what's your standby lifetime after underclocked cpu?
I can see the performance improved when i was watching flash video on browser. But honestly, i dont think there are anymore huge difference after overclocking..
But as the battery life still remains quite well, i will still keep overclocking to 1GHz.. Isn't it a good idea?

lol... What happend to HD and THD games... Did u try playing them at 600mhz??
Overclocking to 1 GHz with the right voltage values seems to be absolutely no problem for Defy.
BTW, does anyone know whether it's possible to set scaling governor to "Interactive" mode under Froyo? Gingerbread kernel let me set it, but I haven't found the way under Froyo.
Battery life was a little bit better, the display and 3G always draw a lot of power.
Standby time got better, but I don't use very low vsel any more due to errors in YouTube and dropped connection of radio streams.
Before I used 300-600-800 at 20-30-48, this was very stable in stability test, but for example Youtube would start showing "error playing video". After I increased vsel, it went away.
I mostly did it to lower temperature, optimal temperature for li-ion is around 25°C according to Wikipedia I think.
I don't play 3d games, they would benefit the most from overclock I believe.
Angry birds RIO for example would stutter for a second or two after a level loaded, but it would become as smooth as at higher clocks, when I wait for a second.
I hope flash gets better, when hardware acceleration gets enabled in Quarx's CM7.
I was running [email protected] for a month straight. No issues at all. The highest my temp reached was 112F after playing games for about an hour straight. I now just run it at [email protected], and it's plenty fast for me. I did some "testing" with all the options in SetVsel. It's not science sound, but if you use the Gingerbread Icon in the notification bar, and are running at stock (800 speed) you will notice when the CPU maxes out it doesn't even reach full capacity. I found Words with Friends to really use the CPU, and at 800 it pings the meter in the orange (The notification icon shows green, orange, and red for "zones"). If I overclock it at 1000 or above then the meter goes into the red. I don't know the exact number it switches from orange to red, but being at stock 800 is well below what the chip can really do since it doesn't even max out the meter. I hope I didn't confuse anyone. It makes sense to me.
weird...my cpu at any game reach the 800mhz
yet even in normal situations like browsing through the files on the phone it reaches 800mhz
and also despite the values i use in setvsel are not high(which is:
24 @ 300
34 @ 600
48 @ 800
)
the phone still reaches maximum 38C when i play games and if i set the value in the third vsel the games starts to hang!!
seems like i am the only one who have these problems..but why
anyone have any idea
im running stock arabic froyo btw
if someone can confirm to me that i can keep Arabic language if i installed another rom using custom restore in nandroid then i would be using prays or official 2.3 but no one answered me about that
anyway the important thing is anyone knows why my cpu temp is always high?
Well ambient temperature is important too. If it is 30°C where you live and your phone's temperature is at 35°C I'd say you are good. If the outside temperature is 10°C and your phone is dat 40°C I'd say there is something wrong (unless you were playing games or watching a movie).
in my opinion, it is definitely safe that you overclocking to the leaked moto level.
however, the voltage is still a mystery.
there's no constant conclusion about this.
i'm using [email protected], [email protected], [email protected], and it works fine for me
I'm getting really annoyed. No problems clocking up to 1100mhz with stock voltage (58). But changing the voltage settings, even slightly, makes the phone more or less unstable.
Hello , i have searched in the forums for the answer to this questions but most posts about it seemed misinformed or just pulling their facts out of nowhere , so i ask again , what should be my limit for CPU (cpu! , not battery) temperature? .
Im running Liquid Smooth 2.0 with NCX v13 kernel , which is clocked at 1.2ghz with interactive , i think n7 values . GPU is supposed to be overclocked at 520mghz but i dont know how to check or modify this (anyway?)
Im really liking this kernel/rom and im getting decent temperatures.... Previously in stock roms , i never ever checked CPU temp , only Battery temp and i thought it was acceptable to have it under 50c (although the Renovate boost thread claims 52c is okay , HTC claims 55c is okay too) but i have an app with an alarm for 49c+ , i have only reached that like 2 or 3 times. So battery temperature is relatively controlled.
CPU temperature i never noticed but became interested after hearing that this kernel was slightly OCd , i seem to run from 45c idle to 83c under heavy load. Tegra games make the CPU get hot really fast , i played 10 minutes of Beach Buggy Blitz and the temperature reached 44.5c for battery (which is relatively low!) and 82c for CPU , the phone didnt even feel hot ,although i have a Trident Aegis case .
Non THD games seem more balanced (CPU and Battery temperature go up accordingly) . So i dunno if i should be worried.. I heard that it can reach 99c but that just seems a little bit excessive .
BTW are there any temperature alarm apps for the CPU? , like a notification or alarm if the CPU temperature goes above a certain limit? .
My HOX has only gone green and red led once , when i was watching a movie through MHL .
I used SysTuner to measure cpu temp and some other app to measure battery temperature.
Thanks for your input .
Hey Guys,
i have a problem with my Nexus 5X since weeks and now I think I have founded the problem. On daily usage, in games or in Benchmarks: the two big Cores are always stopped. Bit I don't know why. I have tested it with some Games, Geekbench and CPU-Z. Can anyone help me?
Thanks

The thermal throttle stops the big cores when they reach a certain temperature. It's "normal" behavior on this cpu.
But they are stopped all time. When I Power on the device and start a big game, when I wake up the device after a while and play a big game... ever! Temperatures are round about 55°C
If you're on one of the Android N Dev Previews then it is probably the well known bug that shuts the big cores off. If you're on Marshmallow then it is most likely thermal throttling. I think the big cores turn off at about 45C.
Okay. But why does my device heat up so fast? I have read a few Tests and the Processor never gets hotter then 42°C.

It's your use mostlikely, e.g. camera (, cpu intensive games, benchmarks etc) takes all the cpu power possible, that'll heat up your device into range of thermal throttling in no time, while one can browser normal websides for hours without any signifcant heat building up.

I think it's a general misunderstanding of how a big.little cluster cpu works. Those aren't 6 equal cores, the big ones are (most of the time) just there for short term boosts and otherwise drag down performance overall, especially when the cpu heats up. I can see a much higher use of the big cores e.g. when loading websides compared to gaming, where it comes down to how the game can run on the remaining cores (little ones) after a few minutes.
But the Cores shouldn't heat up after a few seconds, should they? And they are simply alsways off.
I have tested it with the Geekbench 3, Smash Hit and the Camera App. The results like the temperature and the clock Speed came from CPU-Z.
My Standard result of the Geekbench is 650 and 2500 points. The two big Cores are stopped and the temperature is round about 50°C
The Standard witch I have found in the Internet was 1300 and 3600 points. The temperature shoult be round about 42°C-44°C
Hello xda,
I have been having the erratic battery behavior for a long time [i have the tablet for 3 years now].
I have sent it for maintenance on warranty and they changed my battery but no use!
The erratic behavior occur mainly while playing games i.e gpu workload....
But there was no kernel that allowed me to undervolt the gpu untill now
I flashed lineageOS with the tool deathly auditor and set the maximum gpu freq. To 420 mhz
The problem was alleviated but not completely resolved.
I also used battery HD app to monitor battery percentage and battery volatge during playing games and what i found is interesting.....
The battery suffers sudden sever voltage drops while playing gpu intensive games
This was alleviated by undervolting and decreasing maximum gpu freq.
I hope this helps someone regards.
Rydj
I also forgot to mention that i soldered the battery directly to the board but that didnt help either
As it was thought that the erratic battery behavior was due to cracked soldered joints of the battery connector.
BUT I CAN CONFIRM IT STOPPED SHUTTING DOWN AFTER I SLAM THE BACK COVER!!

Thanks for sharing
I also have the same problem.
I gave the note to my son and got myself a tab-s2, he is not so happy with the battery.
If he plays non intensive graphic games battery lasts hours, but a bit of graphic and its dead in an hour.
Can you please share your undervolt and max gpu numbers?
Do I need to undervolt and change cpu governer too ?
Are you on Nougat?
OP says:
GPU Control:
GPU Time in States - Same as CPU Time in States (Times in each frequency)
GPU Frequency Control (not yet supported on Nougat)
GPU Voltage Control (not yet supported on Nougat)
GPU Governor Control (not yet supported on Nougat)

So I've noticed no matter what kernel I use my gpu scores in geekbench are always atleast 3000 points under the average for the pixel xl, any thoughts on what could be causing it? Maybe I just got a bad one?
Having the same issue scoring around 3000 when the average is 7000. Also really low multi core scores on cpu. Im thinking the battery is old. A new battery might resolve both of our problems. Does yours overheat as well?
