my setup is

using freezer fridge for real i use it i use the side where the cool air flow direct to the phone

and use big copper plate like i said in whatsapp

setup

dvfs 100

2.8 big

2 little

764 gpu

50% zram

and the most important is

CHARGER

made it with max mA

and this phone draw 10W

my device is

G955N

6Gb ram

128 Gb storage UFS 2.1

for watercooling i didn't try yet because my fitting for acrylic still in ship maybe if use watercooling i can draw more then 10W
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@ up

6 GB RAM O__O ?, i've only 4 GB.

Also your phone draws around 17,5 W while running benchmarks @ full speeds. You saw -3500 mA = 5V x 3,5A = 17,5 Watt.

But if you use charger cable with good power source then it'll help the battery and therefore the SoC draws power from USB wallet charger + battery. The graph you see in your screenshot is just how much current or mW is flowing in OR out to the battery.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
wait what ? didn't you know it ? hehe for korean version almost every device has 6 gb ram
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
and i think i touch 20watt+ because i use PD charger 9v 3.5A

i think that flow from battery i guess because i use charger at that time and i see from 3.2A goes down to 1.2 A when use 839 gpu
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I was only aware that S8/S8+ has 4 GB RAM and Note8 has 6 GB RAM.

But it doesn't matter, RAM config and optimizations are still correct on your device.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Rtyu is right, even I was aware a 6GB RAM version of the S8 existed.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Oh no you used devcheck while running the benchmark 😭😭

Devcheck is good for temperatures testing during a test run benchmark, but it takes some cpu cycles. So you could have scored higher. In a serious run, you force stop devcheck and then start the benchmark. On top of that, I see you had a lot of background apps.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
okey i will try again tomorrow
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Also though don't just test AnTuTu. Try out 3DMark Slingshot Unlimited, Slingshot Extreme Unlimited GLES3.1 and Vulkan, as well as Geekench 4 and 5. No need for GFXBench since I already got maximum results there, or almost. In case you test, ALU 2 Offscreen, Driver Overhead 2 Offscreen, T Rex Offscreen, Manhattan 3.0 Offscreen and Aztec Ruins Normal Tier Offscreen GL3.1 and Vulkan are the benchmarks you should run.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
here my gpu score

i don't know why this happen

in antutu i can't run the 839 but in slingshot i can't do test for vulkan i don't know why that not support or no option to do that

here some play genshin it hot to hot i handle haha

you will see at the end of the video it stuck because sufficent power
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I meant Geekbench CPU. Also on Slingshot you can do WAY better.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Like, this is an old score I got on Slingshot Unlimited on 572MHz GPU. And I still am faster than you. You did something wrong. You should be scoring 5000+. Try again.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
what the hell i think 839 not stable that cause lag
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
2,7 GHz / 764 MHz

DVFS 100°C
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Not bad. Since you don’t have cooling, I recommend you run 2574mhz big, 2002 little and 683 on gpu. It will give you better results. Sustained performance here is more important. Because despite your nearly perfect DVFS, 2.7 still is handled for periods of time that are way too little to make a significant difference.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
i am still get low score

but for geekbench cpu i can get same like dev
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Your scores are weird. Why can you get high antutu but low everything else? With 2704mhz big you should get 1850+ on cpu Geekbench
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
yes that my big question WHY !??!?! i see it throttle just got 2.3 ghz and goes up to 2.7 again

i test again and boom goes down 😥😥
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
maybe can i see you temp when test ?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Yea I will try to record this evening
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
umm i mean your highest test history how cool it is ? or even good to record it
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
You mean what temps I reached on my highest score?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
yeah how hot and how cool ypu start there is history recorded in 3dmark
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Because you didn't wait for cool down to ambient temp before you start another test.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
umm i think yes and i think i can do that because the phone at 29°c
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
Random screen shutdown, needing to force restart to get back, sometimes random phone shutdown, here are logs after last reset, any idea anyone?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
check voltages maybe that cause stuck
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
29°C way too hot.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I can do that.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Give us some context. Did you alter any setting? Undervolt? Overclock?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
:v what too hot ? hmmm okey i will try 15
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Much better.
[Samsung Galaxy S8 & S8+ Cross Device Development] madhatter57:
A little bit of under lock , disable boost and CPU temp at 55 degrees
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@madhatter57

I've checked your logs.

Results:

dmesg: OK, no errors found

last_kmsg: log corrupted - that's normal if you had to force reset the phone. (Next time wait 2 minutes to see if phone reboots itself, then log will be usable)

logcat: there are some errors with knox / secure storage. - Are you trying to use secure folder ? - Secure folder feature isn't supported on this kernel. Also I see that Android can't find various files on your /system partition, files for fonts are missing.

Looks like your phone is screwed up.

This can also happen if you already had to restore a TWRP backup from a buggy(!!) sdcard. And that's why I never use the TWRP backup/restore feature. (because my sdcard is at some point buggy)

I suggest to format your micro-sd card, then do a clean install with ODIN but without to restore anything later in TWRP from your TWRP backups. Because otherwise you will restore a buggy /system or /data and this is not what you want.

Good luck in fixing your phone. So later you can enjoy this kernel with full power.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
okey this is i can afford the cpu at 2.7 with

g955f not N

for gpu still i can't get high score due PMIC cannot handle it
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Alright! Now that’s more like it. But you can STILL get more. This phone at 2704 can get 1900. I know it.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
wow 1900 :v okey maybe next time i will try again
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yup .. and even more ... we get 1700 with 2314 MHz, so we can calculate how much we get with 2,7 and 2,8 GHz with proper cooling. As you can see it's 2062 points.. and that's likely not all .. because calculation is made based on stock freq 2314 with stock cooling system, which of course throttled CPU freq during the test.

So real score for 2,8 GHz is likely around 2400 points ! (Note10+ level)
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
its hypothetical. Unfortunately overclock scores in my experience do not scale that well. However at 2808MHz we DEFINITELY can go above 2000 if no throttling happens. But 2400+ probably impossible

Another further proof for that is that E8895 at 2808 in single core seems still about 10% slower than snapdragon 845 and it also runs at 2.8 (2841). And best I’ve seen from 845 is about 2250. So 10-15% slower than 845 is about 2000. 2000 still a lot for a 2017 soc. It’s Exynos 9810 stock territory.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Hey @ace2nutzer you gotta answer this.

On a scale of insanity from 1 to 10, how insane is somebody who removes throttling thresholds from a phone that already runs VERY hot?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
10/10 ... why ? What happened ?
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
xxTR kernel dev made a flashable zip to remove thermal limit from E9810 devices ☠️☠️☠️☠️☠️☠️🤣🤣🤣🤣

On top of that he raised boot frequency from stock 1794 to 2314

Bootloop time 🔥🔥🔥🔥

He completely removed CPU sensor temperature sampling. So the SoC IN THEORY only shuts down when it reaches emergency temp (115C), but maybe not even that
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes, I know it's possible, but it's quite useless since it'll reboot even at stock freq 2314 MHz. But if you decide to limit freq at max 2 GHz, then it may runs stable. In my case hardware limit is around 118°C. But such temp sensors have likely a tolerance of +-10%... and the max allowed safe temp is 100°C. That's why my driver limit is 100°C. But it still goes for a few ms over 100°C.. around 105°C.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Yeah but again, pushing 110C and more is dangerous for the lifespan of the chip. That’s why it’s just insanity to remove the limit
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
I don't think that you need to explain it to me, but for noobs it's for sure a good info. (y)

Yeah.
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Well to my knowledge its possible to break the cpu/gpu chip if you run it too hot. But if you run it normally its kinda impossible to break one, especially pc cpu's
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
this about hotspot temp and we are use the smallest cpu size and did you know amd made cpu they are still find how to get near to the hotspot and we are just chillin with our soc run at 100°c hahah

DAMN ACE BECAME A MOD? Congratulations mate
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Damn congrats dude @ace2nutzer
[Samsung Galaxy S8 & S8+ Cross Device Development] kryptoalinian:
Hi guys, can anyone give me some reviews about the kernel? I'm thinking of switching back to stock ROM and try out this kernel for maybe better performance, battery life and general smoothness. Any pointers suggestions are appreciated thank you.

Keep in mind that I'm a complete newbie, and will not understand most of the jargons, HWC, Swap etc. I've been experimenting with custom ROMs recently, tried the LineageOS. They are great, the up to date Android is amazing, but I did not use it enought to form any opinion.

Been using the hades Q v3 ROM, while amazing, for some reason I believe it has its own issues. Phone is heating up a lot more, battery life is abysmal.

Will this kernel with stock ROM solve general Samsung overheat issues and maybe give me good battery life? (Stock already gave me very decent battery life.)
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes it will and even higher performance. But note that if you need full control over the app a2n kernel control to adjust CPU/GPU temperature and higher CPU/GPU freq, OC up to 2,8GHz stable and GPU up to 839 MHz and charger control and many more, that it's not for free. Price is 4 €. But kernel is for free.

You can even test for 1 week, if not satisfied you can ask for a refund.

With kernel default you get better battery lifetime and fix overheating issue, but performance is worse if you don't tune it.
[Samsung Galaxy S8 & S8+ Cross Device Development] kryptoalinian:
Like I said I'm complete newbie, so I don't think I'd want to tinker with the OC and CPU/GPU stuff. Just looking for a set kernel or ROM I can just flash and use as a daily driver.

Sure it fixes the issues but if performance will degrade for no reason then I guess I should just stick to default samsung stock kernel.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Hmm not really, the stock kernel is quite painful. Even the fact that you get with defaults lower benchmark scores, it's still more smooth and faster response, due to countless of optimizations over the years. Yust try it out. 👍
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Yes it will fix samsung general issue about heating so much and it will give you batter battery like dev use this kernel and get 10h SOT (Screen On Time how long the screen on or how long you use the phone) and for overheating issue that well fixed me as overclocker and tester has test di kernel long time it fix all problem from stock kernel problem
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
If you use this kernel without app manager you can still get better performance with default settings almost same like stock kernel but

NOTE: if you live in 36°c everyday almost all the phone in the world get overheating me in my country who always has 36 or 34°c room temp

The performance WILL NOT degreded based my experience using debloated rom from hades rom pie

And BIG NOTE if you use this phone with much social media this is will decrease performance little bit because social media app is kind of heavy background use
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
This is the best S8 kernel on the planet, because it keeps in mind newbies and expert users.

The stock preset already immensely improves over stock kernel experience. So you don’t have to tinker with anything at all.

Admittedly the true potential shows up the moment you know how to tinker with it, but this kernel is the best of the best for S8, and the one that will give you the best experience even when keeping it plug and play.
[Samsung Galaxy S8 & S8+ Cross Device Development] kryptoalinian:
Thank you for the insight. I will definitely give this a shot.

Can I use this with another custom ROM or is it best suited for stock?
[Samsung Galaxy S8 & S8+ Cross Device Development] kryptoalinian:
I see, thank you for the response! Will definitely give this a go.

How has your experience been with the hades rom with this kernel? I understand it can heat a bit that's no issue, but I was using hades Q v3 ROM and it was overheating way too much! And battery life was very bad. Are you running the hades Q v3 ROM or the other hades stock pie ROM? In general how has your experience been with this kernel alongside hades ROM?
[Samsung Galaxy S8 & S8+ Cross Device Development] kryptoalinian:
I'm currently running the horizon custom ROM, it's on Pie with One UI 1.0, much like stock. Can I install this kernel with this?

I have TWRP and Magisk installed already. Shall I just flash the zip through TWRP and that will do it right?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
You can flash this kernel on every Android 9 ROM. I recommend to use the stock ROM, but Hades stock pie ROM or that one from Alexis should work as well. Horizon may be the fastest but has a few bugs. If twrp is alerady installed, just flash A2N kernel and then magisk for root. If you fash this kernel for the first time, I suggest to wipe cache and dalvik-cache in twrp. This gives you additional boost when you open apps.
[Samsung Galaxy S8 & S8+ Cross Device Development] kryptoalinian:
I'd like to first give it a go with Horizon, since it's already installed and is Android 9. I have TWRP & Magisk already installed shall I just flash this zip and be on with it? Also will it boot normally or first boot after flashing will take some time? Just asking so I don't freak out if phone takes 10 - 15 minutes to boot haha
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I use hades pie rom of course because this kernel only run on android 9 only
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Just flash install magisk done
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
That will boot normally

It will boot normally
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes after wiping dalvik-cache booting takes around 15 minutes. During this time the phone will heat a bit and it's normal.
[Samsung Galaxy S8 & S8+ Cross Device Development] qbert79:
where can I find old kernel versions?
[Samsung Galaxy S8 & S8+ Cross Device Development] Ryujin96:
Nowhere. Becus the old versions are buggy or crash sensitive
[Samsung Galaxy S8 & S8+ Cross Device Development] qbert79:
too bad, to me the latest version gives me problems with the camera.
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Yes I know, already fixed it mate.

New kernel & app release in a few hours available.
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
wait, what camera issue? i'm pretty sure my camera is working fine :D
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
You can check it lag when photo mode it like stutter i am sure for it
[Samsung Galaxy S8 & S8+ Cross Device Development] Twiq:
no, i don't have this stuttering, tried all different modes and seems like nothing is wrong, tried zooming in zooming out, using filters, pro mode iso and AF.. swipe all directions on each mode and can't see anything wrong.. switch to powersave mode also giving me same results

is it device specific issue?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
Steps to trigger the issue:

1. open the stock camera --> foto mode ..

2. switch to video mode

3. switch back to foto mode --> move the phone and it should lag.
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I tried so hard to make GPU work stable at 839MHz even with optimal battery voltage (4.4V) but even at a very high voltage of 810mV it just didn't manage to stay stable in Honkai Impact 3rd APHO 2 at max settings. I guess 764MHz is the actual reasonable limit for most people. That map boasts very advanced effects such as global illumination and volumetric lighting, so it only makes sense that our little G71 can't manage to run the game well even at high frequencies. At 764MHz the average was 24fps.
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Bro to get stable at 839 use charger and set to 3.2 A it will be work same like me this phone use like 15watt power

If not stable too okey you got your limit
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Dude I made sure the phone was getting optimal power. That is not the issue. 839MHz just isn't stable for me. I probably would need 850mV to make 839MHz stable but it isn't worth it. 764MHz runs at 730mV and performs just 10% slower but runs much cooler. It's the limit
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
One thing to get run 839 little stable just made it 810mv if not tho yeah you are at limit i have s8 plus that cannot stable at 764 :<
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Mine is rock solid at 764 but 839 for games just no go. It works in benchmarks though
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Btw i have 2 s8 plus 1 has screen second no i ussually gaming on no screen using dex and you know ? When i use charger pd charger from xiaomi 33 watt charger it can hold at 839 mhz flawlessly i don't know why not work at your side but on benchmark it cannot work but in genshin impact it run 60 fps when see sky :v when battle is like 35 to 45
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
It can hold 839MHz flawlessly because silicon quality is what matters. My silicon can't handle 839MHz without a voltage too high. What voltage do you use for 839MHz?
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
I use 839 at 810mv for sure 810 is good voltage because our PMIC limit the silicon is fine this about distribute power problem at the end we must have lucky mainboard with better silicon

Better silicon = better efficiency
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Even if our PMIC can handle that voltage I am afraid that it's too high for the chip. 810mV on GPU seems very high. I think my 839MHz is probably stable at 830-850mV but I fear that voltage would burn the GPU
[Samsung Galaxy S8 & S8+ Cross Device Development] rtyuakatsuki:
Nah nope bro it will not burn it i was test it we have 20core it took big side of our SOC it will not burn the soc the burn is from cpu because it has little area for it that why when we set it to 2.4 or 2.6 it eill jump to 90°c

Some test fron me using 839mhz it increse to 95°c it slowly when i idle at 30 it goes to 95°c took 15 or 30 second using funcooler is like 3 min
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
Our Mali G71 MP20 at 839MHz (Slightly throttled) is able to match Adreno 630 in shader and ALU performance! (G72 MP18 at 598MHz scores 49fps. We are fast!)
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
@qbert79

New kernel release is shortly online.

In the meantime you can still use the Samsung stock camera (it lags but it works) or flash the stock kernel (S8).

Nope, the DVFS driver will reduce freq step-by-step until min_freq if temp is higher than 100°C. And if even at min_freq temp is still > 100°C it'll simply shutdown the phone instantly to avoid damaging the SoC by overheating. I've tested it on my phone 839 MHz @ 1000 mV running benchmarks without any issues. :)
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
So 850mV voltage is not dangerous for GPU?
[Samsung Galaxy S8 & S8+ Cross Device Development] ace2nutzer:
No, no and no. As long as you don't go outside the A2N app specs, you are safe with every setting. The worst case is unstable setting, that's all. And the only thing is that it'll increase the heat and therefore will throttle down to 764 with a lower voltage. But as long as even with 839 MHz it'll stay below the adjusted DVFS max temp, you will benefit from higher speed. And of course it'll increase power usage.

More power --> more heat (--> better cooling) --> higher speed. :D
[Samsung Galaxy S8 & S8+ Cross Device Development] TechNoobForSale:
I know how it works Ace. I’m just asking because heat isn’t the only thing that can kill a processor. It’s also voltage. Either way if 850mV is fine, then I can most definitely run 839.
