Noticed that. There's definitely a problem with antutu CPU temperature detection. Thanks for the info

[Q] FAUX123 Kernel Question

(((("The devices range seems to be huge. Not being interested into scores that much I had not tried Antutu on my S4 to date but did a few minutes ago:
On my rooted stock Vodafone Rom the Antutu score with Faux 3m stock settings and stock CPU clocks is 24.413.
Lowering the CPU clocks to between 324-1674 and changing to mpdecision off and intellidemand it is 24.221...
No problems with Antutu - both scores fine...
Edit: taking a closer look it seems to me as if Antutu overwrites the upper CPU clock limit somehow. The 1674 before running Antutu popped back to 1892 when checked after Antutu had finished. The lower limit remains untouched though - strange... At least the resulting scores are consistent - 2nd run with the second settings setup ended with equal 24.370.)))
How are you able to do the test???
As soon as I start Antutu, It bounces out from antutu and no mather if I lower the frequency ,still same result.
i think it is an antutu problem my galaxy s3 was getting lower scores while i was overclocking :/ maybe when the app gets updated it will be fixed

Yea it's a problem with AnTuTu, after you play with your phone's frequencies, it force closes. Sometimes with Quadrant too. It's weird because benchmarking apps are almost ment for testing your phone with overclocking, you (we) should contact the dev!
Thanks for you reply.
Yes,Antutu seem to be the culprit.
Funny though some are able to do the Benchmarking without a problem.
I do enjoy the smoothness and stability I find in FAUX Kernel for my Galaxy s4 9505,dont really need a benchmark to tell me if its good or not.
Anyway would be fun for comparison.

Exynos 5210 voltages

Hi All
I have a question on the voltages on the Exynos 5210 on the i9500 s4. I couldnt post in the Perseus thread as I have less than 10 posts.
Basically I am running the persues kernel to undervolt. I am seeing the big cores A15 at say 1200mhz running a lower voltage than the A7 cores at the same rpm.
Why is this? Isnt the A7 supposed to be more more efficient hence run a lower voltage?
Can anyone please explain....
Bump for some help...
BUMP!!!
No one has any idea on this?

le 2 ( snapdragon varient) performance issues

Devs,
The performance of le 2 is very bad when it comes to gaming.
It is the same in every stock eui to miui and all lineage os ROMs like AICP which uses lineage is kernel.
As per my finding this is due to severe thermal throttling in eui as well as in lineage os 13 and 14.1.
Firstly the two A72 CORES don't run while any task making it like SD 650 and clock go soo down at reaching 34° to 35°c and at above temp all A72 CORES ARE DOWN in lineage is and only one works in stock eui, same goes with GPU under clocking starts at 32°c making gaming experience horrible,
Even kernel auditor don't have any control in any of the ROMs and in lineage is 14.1 27 Feb build it is told it have core control but it can make all A72 cores run couldn't control clock speeds and result is the same ,
So I request devs please make a kernel from scrap and don't take hints from eui kernel and give us good gaming experience.
Thank you

My findings were exactly same as yours, the cpu and gpu, both are underclocking for even slightest of temperature rise. This is bad, but the good news is, I figured out a way, by which we can disable this poorly configured thermal throtling.
Delete this file here: /system/etc/thermal-engine-s2.conf
I don't know it it is safe or not, but I have been gaming with my device after deleting this file for about 10 days and there is no explosions yet. Hahaha.
Also, if you want, instead of deleting this file, you can modify some parameters so that, it starts throttling after some really high temperatures, instead of current values, but I like deleting that file because some thermal throtlling algorthm is always embedded in soc anyways.

See your findings are correct but I myself renamed thermal config s2 but it didnot have any effect and at 33 ° I can see GPU under clocked at 432 MHz and CPU under clocks itself , and at 35° the lagging in games can be seen easily
Will try deleting the file also ,hoping it can have any effect

My cpu temp have gone over 60°c but I haven't seen any throttling in cpu or gpu. But when, that file was present, those temperatures were never reached because of thermal throttling.

Deleting this file is an absolutely terrible idea. Modify it instead.

At first, I thought the same. But yesterday, i have played asphalt 8 in bright sunlight(to test if there is some thermal throttling left embedded in soc). And I was right, it throttles down the gpu, big cores, small cores, even some cores went offline automatically. After the device was cooled, everything wqs back to normal. So, IMO, there is no harm even if we play in extreme conditions with the file deleted, thermal throttling will kick in when its needed. Although, I advise modifying the file to others. Hahaha

Thermal throttling happens even in the best chips. Most of the time, it's integrated in the lower level portions of the chip.
Just let it be, really. Thermal throttling is the way of the chip of protecting itself from heat damage. PC processors, for example, shut down when removing the fan and reaching critical temperatures.

Ya true it is present in every chip but optimizing is Also a thing right.
In le 2 the two A72 cores don't run at all above 30°(except when opening apps while it is cool ,so after 33 or 34° they are not used in anything,and 34 is average temp of the phone while using ,that means it just exactly works like a loweclocked SD 650 which even more throttled with each degree rise in temp and at 36 ° ( which is avg temperature while gaming ) phone turns off one more A72 core meaning three A72 cores are off and one a72 is throttle to around 800 mhz and even all a53 cores run at half clock speeds and till that time GPU also reaches below 350mhz and lower a and it impossible to run even minor games like subway surfers lag free,
And since lineage is kernel has taken hint from eui kernel ,it performs exactly the same as stock kernel which leaves us with no choice left.
 @codeworkx please look into this issue and please build a kernel for gaming performance as SD 652 is getting wasted due to thermal throttling, @codeworkx I am sure you know this issue better than me ,please find time to work on it.
@shivamg95 deleting the thermal file couldn't help this

It is not working and would have been not working for you also just check with kernel auditor,
I have check it thoroughly .
I think you don't know how to check
Tell me the process you check

First i make the soc heat by playing games or running benchmarks, then i open kernel auiditor and check if maximum cpu freq gets lowered or automatically or not. But it doesn't happen after deleting that file. Also, the gameplay seems very fluid then before. I also check for gpu max freq.
Hey, I have Cool 1 (same Soc) and yes, very dissapointed because in second 1 starts the throtling...
I have Kernel auditor. Which settings should I force?
hello, very nice threat.
I had some different experiences.
For me throotling starts slightly at 37° and bigger at 39 or 40 ... this results to throotled big cores at 1248mhz and a gpu to 432
to avoid that I made some underclocking settings which gives my setting antutu score of 69000 instead of 82000 and a geekbench score of 1000/3500 which is giving me cool and fast gaming enough

Oneplus 2 Overclocking Help

I am Noob to Android Development,,, I am having Oneplus 2 and installed Boefla kernel .. When i overclock my A57 cores to 2GHz my phone suddenly turn off and Turn on again after sometime... My question is Snapdragon 810 running on xperia z3+ has 2Ghz A57 ... So I am also want To Keep my phone stable at (A57=2.0 ghz ) .. i dont bother about Overheating or failure... I am Doing this at my Personal Risk.. So Please help me out
The 2 uses the 8994-V2 which is a lower binned chip than what some devices ship with so there is a slight variance in what frequencies and voltages chips can handle as with every CPU. These are not tested above their spec so you may very well have a dud. Another thing to keep in mind is that a higher voltage may help. Use 5mv increments until you no longer see the issue.
That's really it. That said, the 810 heats up enough. Over clocking will only add to that. Not to mention we are already seeing reports of cores dying and everything. So it really isn't something you should do.

S20/+/Ultra BENCHMARK TEST BOOST

The only way to boost the benchmark on EXYNOS S20 is to benchmark it on the freezer.
So the temperature of the processor doesn't go up to 70'C so you can fry eggs.
Here is my test
BTW i think this phone needs a serious kernel optimisation, and antutu temps are shiet, its telling me 50° idle while CPU monitor and others shows about 37°..

The thing is that the s20 doesn't get the same results after 2 or 3 antutu benchmarks in a row.
The cpu temperature rises and the performance drops down quickly
Its like a mid range phone.
No worth £1200
