Hey, for some reason performance on my Note 5 (N920I) isn't up to scratch. Basically in Gangstar Vegas 4 it lags, and any graphics benchmarks it is VERY low. I've restarted the phone. Factory reset, updated to latest firmware. Its the first time I have this issue with the exynos processor (I always had snapdragon processor b4 for my previous phones). Is everyone else getting this issue?
Thanks. :silly:
The govenor settings is set to Interactive, which is bad for some games like PPSSPP emulator and Angry birds 2 from what i've tested.
U can do two things but that requires Root.
1)Using Wanam Xposed for lollipop, you can disable DVFS or create a blacklist of apps that DVFS won't be used, i suggest the blacklist. DVFS is throttling the device way too fast and does more harms then good.
2)Set A57 A53 CPU govenors to performance, or if u have Arter or stock kernel, just set the interactive to performance, make sure phone is between 25-30C before doing any benchmark, and go ahead test your games.
If you need more info, can PM me.

Hi guys, I'm running RocketRom v23 with kernel AbyssNote v4.2 which I assumed the CPU has steps from 50 - 1704mhz by default. However when I use CPU spy it shows 1400mhz maximum. Also, Antutu benchmark shows my CPU is running 1400mhz. If I want to try out the overclocking ability, do I need to install app like SetCPU or does the kernel handle it by itself?
Why not just install SetCPU and try it for yourself?
The kernel probably isn't overclocked by default because different phones have different overclockability. One Note could be randomly rebooting at 1450MHz while the other works perfect on 1700MHz.
Just make sure you're aware of the risks involved in overclocking and also be aware of the minimal impact it would have on a phone that already runs everything you throw at it fluidly. In my opinion overclocking a phone like the Note is only really viable to get higher benchmark scores.
Hey guys !
I started monitoring cpu cores on galaxy s5 ( g900f ) and I saw that after a while of use all 4 cores randomly get stuck online ( just like my previous galaxy note 3 N9005).The issue is due to TW DVFS( DYNAMIC VOLTAGE AND FREQUENCY SCALING).Start monitor your cores with perfmom or system monitor or whatever and post your findings. Have fun and maybe some of you can start a petition for Samsung to disable DVFS !
Fix for non rooted :
*nothing permanent...only a reboot can fix the issue untill it happens again.
Fix for rooted :
*reset mp-decission or add a script to reset mp decission every day at a hour you decide ( not permanent )
*install xposed framework with samsung dvfs disabler module from playstore ( from what I tested disabling dvfs in wanam xposed doesn't work ) - this is a permanent fix
DVFS Disabler not working?

For now no more 4 cores stuck online with dvfs disabler on but I need to do some more testing.
Does this happen at random?
Are there any symptoms?
Have you tried this: https://play.google.com/store/apps/details?id=com.mugich.cpumulticorecontrol
I have succesfully disabled two cores, but whether that helped with battery that might be a difference story.

Yes it happens randomly but disabling dvfs did the trick with 4 cores stuck online.

I will but it doesn't bother me if it runs with minimum 2 cores if doesn't affect battery life. Will report later.

I'm sure the battery penalty of having 2 cores online at 300mhz over only 1 core would be minimal but I have also noticed the issue that sometimes all 4 cores will stay online despite very low cpu usage. All 4 cores would be clocked down to 300mhz but essentially doing nothing with only 5% cpu usage.
Edit: Like with you, a reboot solves this issue. Either way I have not noticed an impact on battery life.
An excelelnt way to easily monitor which cores are active is a free app called "CPU Stats" which shows 4 small cpu usage bars in the notification panel.

I use perfmom to monitor my cores. It's free if you download it from chainfire's thread or you can pay for it in playstore. Btw I didn't get anymore 4 cores stuck online since I disabled dvfs with xposed + samsung dvfs disabler module from playstore. Also battery life has improved just like it did on my note 3 since I disabled dvfs.

Wanam Xposed has a DVFS disabler too, reckon that will work the same?
Also isn't DVFS implemented to prevent overheating of the device under stress? Could you explain why it would increase battery life if your CPU cores were fully "unleashed" without temperature throttling?
cheers

On my previous device (Note 3) disabling dvfs through wanam xposed didn't worked (some other users tested with the same result) . Temp throttle still works with dvfs off and as for battery life with dvfs on when all 4 cores get stuck online I get less with 1h and 30m on screen compared to dvfs off and also there is much more heat running with all 4 cores online so I used Note 3 with dvfs off from February till this month when I bought gs5 and had 0 issues with heat. I would also love if someone could start a petition for Samsung to disable dvfs because it causes more problems than it helps.

I couldn't find any specifics when I googled it, sorry, but what is DVFS intended to do? It dynamically sets the voltage depending on CPU speed to save battery or something? :S

I quote: "After that DVFS is completely disabled! Kernel can handle totally the power of cpu so the up/down scaling! Cpu and Gpu freq are not blocked anymore! The cpu and gpu are used based on tasks and not limited by crap samsung behaviour".

I remember on the galaxy S2 this was simply an app that could be disabled using most root tools! Fortunately I still get anywhere from 5-7 hours screen-on time on the S5 (brightness dependant) whether this bug is present or not. Does the cpu frequency still respond according to the governor? I noticed the S5 regularly increases the minimum cpu speed to about 1.1 Ghz (not 300 mhz). Does this behaviour remain with the mod? I'm just curious because with the great battery I'm happy to meed anything that improves smoothness.

so what app do you use to disabla DVFS ? are there others than xposed module (by wanam) ?
Has anyone noticed a difference on the new Lollipop firmware for either the S5 or the Note 3? Does this issue persist? All the 4.4.2 builds on my S5 seem to have this!
Any updates on this issue?
Is it actually SAFE to do this, as long as you are not Overclocking? Also, does this option in Wanam's Xposed module work for this now? Or still no?

I have seen no further updates and as far as I know it is safe, it simply transfers control from Samsung code to Qualcomm code. However, the Samsung thresholds for thermal throttling were lower which means that they can be seen as more 'protective' at the expense of reduced performance. I use "CPU Stats" in the notification bar to monitor the issue of cores not sleeping (and general CPU usage) but as far as I know there is no official fix available yet. I am also not sure about the Xposed module, did they say there was an update fixing it?
i know that soc is an 8026 but how many core and which gpu are in that snapdragon on GWR? Because somesay that it have 2 core and adreno 220 and someone else say that it's a normal quadcore with adreno 305
You might want to check this thread:
http://forum.xda-developers.com/g-watch-r/orig-development/kernel-intersectravens-kernel-t2957728
It has all 4 cores, with max speed of 1.2GHz (I think?)
It comes with only 1 core enabled out of the box on the default kernel, but it's possible to enable all 4. The problem is of course battery life, and it makes a huge difference when you enable all 4 and start playing with the watch.
It also gets quite (uncomfortably) warm for example during the initial synchronization (when all the apps are installed/compiled by ART).
A good compromise is 2 cores limited to 800MHz, which is what I'm running right now (a default setting on the kernel I linked in recent versions) and I cannot complain. I think it now actually drains less power than stock (some optimizations were added) and it is a lot more responsive. There's no need for more power anyway.
dear modders
i just want to say i overclocked my htc one m7 cpu from 1.7ghz to 2.1 GHZ
with a custom kernel called ElementalX-m7-22.3-Sense
is this save can the phone run this without any stability issue's or shall i downclock it to 1.9
i use M7_Sense7_artmod_10.0 rom Lolipop 5.0.2 with sense 7 cause this is the only one without any bugs like no sound when you got called or sms sound's no boot sounds
i fixed my boot sound anyway on this rom
so my question is wont my phone be fried by this overclock cause i saw in the aroma installer that it can be overclock till 3 GHZ
greets Rubenownz
Overclocking the CPU in any system usually results in 2 main things:
a. Significantly shorter battery life.
b. heating issues.
sometimes (less frequently) you might experience a crash and fc here and there.
So yeah, it won't be all rainbows and butterflies.
PS: you probably won't reap the benefits of your now overclocked CPU without an app like no frills CPU or kernel Aduitor. Your device's performance isn't just about its CPU frequency, there's the min Max frequency your system is allowed to utilize, the CPU governor, and the I/o scheduler..
and
PPS: don't and I repeat DO NOT go anywhere near 3 GHz.
good luck.
I'm runnimg 2.1 Ghz OC for over 2 years without any issues. I would like to note that 2.1 Ghz on Elemental was not too stable for me, so I ran that on 2.0 Ghz. Anyway - i don't have any issues with my kernel, no overheating, battery lasts 100% same as stock frequency, no reboots, everything works as it's ment to work. If you really want to run on that frequency, make sure you set your voltage table to match your CPU clocks. Undervolting is not a good idea on such high clocks, so you might want to raise your voltages for higher frequencies a bit

ok mate
yeah i could raise also min clocks might turn that a noch up
just was wondering if it was possible without any harms
there are now on 384mhz 1 core is always active and 3 others are sleeping aid64 tells me
the temps are now 29 celcuis for 2.1 ghz

yeaah the kernel has those options in aroma installer it set it safe i ques
ill post later some picture's of what ive been doing
good nites
here are some pictures of my sense 7 5.0.2 android system dump of htc one m9 for htc one m7 xD overclocked
some temps and cpu tweaks and ofc of the system (dont mind about the girl on the screenshot its my girlfriend not me iam a boy
btw i removed phone number on call menu cause it's private

Its any chance to make all 8 cores working?With root and some script will be possible?
They do under heavy loads. A57s pressure the battery so much and heat without cooling if work continuously. I heard A73s work continuously like A53s.
@Oveana cores got disabled on nougat and that's true!! We can't deny this!! Enabling 6 cores by default as in MM would be soo great or leaving a toggle to enable device performance to use 6 cores is a better idea which we CAn expect in future updates!!
Still no solution??
@Pwruser Its verry annoyng ,SONY DO THE WORST work ever and a fraud Maybe devs can modify kernel to make all cores to work
Get back to MM!! That's all u can do for now....Or flash a custom kernel If u r not on warranty!!!
Big cores work like mm
https://ibb.co/geGYiv
All cores are working with my Sony Z3+ with Nougat .376. By default, only 4 cores run with min frequency, other cores will start running only if there is load, it is for saving battery. You can check with "Kernel Editor" app (rooted only).
flash androplus kernel and enjoy 8cores!
@yxtl there's your answer,
also: having all 8 cores active on max performance lets the device run into thermal limit FAST,
thus ==> lots of throttling, performance goes down, lower than snapdragon 808,
do you REALLY want that ?
Just observe what the big cores do once you raise load on the device ...
And that changes things exactly how ?
Explain ?
Is there a difference in behavior of hotplug ?
(I'm curious)
Thx for answer I run some testes myself ,and A57 cores are not complete disabled ,just need more pressure to work,I asked to sony support and i got same answer
