Thanks Andrei for an answer. it's a big loss that you are not able to upgrade headphone SQ but still I hope that somehow in a future updates you will find a solution to make some fixes for better because as every wolfson this one on note 4 have big potential probably as well.

Thanks and best regards !

Each SOC is different in handling. Mine was ASV1 the second worst volt table for our chip by stock. This was same for all of the voltages for me. Gpu, A57, A53, Mem etc. After some testing I am stable accross the board on ASV10 a couple handled asv15 voltages for me but for now ASV10 on all tables made a huge improvement in temps. ASV15 being the lowest stock volt table available. Just goes to show that stock testing for our Exynos 5433 doesn't necessarily match the proper ASV to your SOC so we are best trying to test ourselves to find the best volt tables for our device. Good luck I hope you make some good progress. The volt tables are at the bottom of this GitHub page thanks to Andrei.

https://github.com/AndreiLux/ref-3....arm/mach-exynos/include/mach/asv-exynos5433.h

There are six headings at the bottom those are the ones I found corresponded to my 5433.

volt_table_cam_v3 (Cam/ ISP Image Signal Processor) , volt_table_int_v3 (internal bus), volt_table_mif_v3 (ram), volt_table_g3d_v3 (gpu), volt_table_kfc_v3 (A53 cores), volt_table_egl_v3 (A57 cores)

I always found the stock Powersave function fair enough which caps A57 [MENTION=5365914]1400[/MENTION]mhz which has been a common powersave frequency for Exynos in the past. The A53 are very efficient even up to 1500mhz.
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
No such thing as "proper" ASV, just different test scenarios. Samsung tests those ASV groups based on a wide range of operating temperatures and high loads. It wouldn't be acceptable for the stock device to crash at -5°C but that scenario is not realistic for most of us so of course we'll be able to go lower.
[Galaxy Note 4 Q&A, Help & Troubleshooting] alvaretto:
Hello, I was checking the tables you mentioned and was trying to understand how to match one of the columns to find my ASV. I was wondering if you could provide some guidance in how to do that. Thanks in advance.

As I saw this thread, I was so happy to see this great kernel living. I remember the great time with my lovely Note 2. Perseus kernel was the best kernel I've ever had on my Note 2! As it was only for Android 4.1.2, I had to flash a lot of other kernels after I updated my device to Android 4.3 and 4.4.2. But there was no one that was this stable, battery friendly and smooth! I created the best profile (for me) with STweaks to get the best battery time and smoothness on my Note 2. Only this kernel was able to let me do this and to take my Note 2 to the limit.

And now, after I fully destroyed the display of my loved Note 2 (don't ask), I'm on Note 4 Exynos. It's like the "big" brother of my Note 2 and I hope for a similar great time with it. And with perseus kernel, It think it will be even better and maybe Perseus will be the next best kernel for this device :) Hope for an official release of Perseus kernel! :fingers-crossed:

For now, I want to thank you for this great work! It was a great time on Note 2 with this and maybe it will be the next great time on Note 4 with this! THANKS! :)

Hey guys, I am facing some problems here and I need help.

After flashing alpha14 I installed Synapse from Play Store. But opening Synapse I am facing this...

I have already noticed that this seems to be a known issue and rebooting the phone several times should do the trick to get Synapse working - at least for a few users in here!?

But rebooting my phone I ended up in a bootloop. I can not even boot into the recovery menu and have to pull out the battery. After wiping cache and dalvic cache the phone finally boots up again.

Giving the phone some time after reboot I tried opening Synapse again and voilà...

Rebooting the phone would end in a bootloop again.

So...any hints on this guys?

Advice is much appreciated...

Here are my phone stats...

As Andrei said our determined asv accounts for extreme conditions cold and hot and it was wrong what I implied that there was an ideal asv. We surely can drop below what our asv is but it lowers handling in extreme conditions. What we consider stable is not necessarily what is truly stable in all conditions but we all may not need that kind of stability in our own usage patterns.

Here is a PDF guide I made for you of the voltage table to match up in Synapse.

[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
I didn't test it out yet.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
How much undervolting have you tested?
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
Big cores -100 till 1400 inclusive, and -106 below that. Little cores -75 throughout, and GPU -87.5 except on 600 where I only got -62.5. -37.5 on MIF except -25 on two top freqs.-25 on INT. Didn't bother with ISP. ASV6.

Been steadily lowering voltages over last few months and this is as low as my unit goes I think.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Konskl:
Andrei is your kernel undervolted by default or i must tweak it on my own? Thinking of flashing your kernel tonight. Thank you in advance
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
It comes with stock voltages.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
If it is okay i can answer you. This kernel is not undervolted but has the voltages available for tweaking/undervolting as you prefer. It uses your stock voltage table/asv that has been tested for your specific device for the stock voltage used. The A53 cores are limited to 1200mv, if you have asv 0 or 1 that will just set your stock volt for example for 1300mhz stock max for a53 at 1200mv max not the 1212.5mv for example that an asv 1 would use. Users with higher asv numbers have lower voltages for the same frequency. Asv ranges from 0-15. Same goes for example on the gpu. Im on asv 1, stock max volt for 700mhz for example is 1137.5mv the max volts for gpu is capped at 1100mv so it will just use 1100 there instead if you go to start to set your voltages in synapse kernel tweaking app by Andrei. These max volt limits imposed are actually good as the first few asv have some fairly high volts. Andrei has great experience on Exynos and I am sure you will be very happy with his kernel. Just open up Synapse after installing the kernel and start having some fun :) cheers

Sorry Lodix was typing reply as you posted yours lol
[Galaxy Note 4 Q&A, Help & Troubleshooting] Konskl:
So if i get it correctly... The higher the asv number the lower the voltage. I must be targetting i guess for the highest asv number that also keeps ky device stable without random reboots right? Btw Ty for your answer.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Tauras:
Thank you for your answer. I really want the overclock and when I think about a Lollipop ROM with S6 features as well as Perseus Kernel and overclock, I think how awesome my phone would become. ;)
[Galaxy Note 4 Q&A, Help & Troubleshooting] MEGAX91:
i have Flickering problem in gaming with v14.

i think A53 Cluster cpu voltage is low for 1700 & 1800 MHz.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
I would check your volts usually what causes that. Gpu volts and if you adjusted any of your BUS volts like MIF/INT/ISP especially I had flickering stuttering when i had Image Signal Processor volts to low. I went to stock on that one at this point like Andrei has left his.

1600mhz is much more feasible. If you want more volts Ultimate kernel has a something like 1350-1300mv limit I can't remember which may get you stable on 1700, havent seen anyone post a stable 1700 on A53 though. I doubt Andrei would recommend higher volts on A53 as these cores are so small and it truly would be fairly easy to burn out/fry your cpu.

In the desktop/laptop world overvolting too far will inevitably lead to Electromigration. This is true for mobile devices and possibly more so for mobile. A desktop has a lot of thermal headroom, laptop has less, mobile device like tablet or cell has little room and like some laptops that have no fan etc use passive cooling to lower the heat under heavy use by lowering mhz to a level which holds a safer temp/power draw. Because heat in the devices can build especially between battery and the fact that SOC (system on a chip) has almost all components to run the device built into one chip we are truly presented with the worst possible thermal conditions out of the majority of devices and computers out there. Therefore one must be very careful going far beyond a manufacturers stock defaults for voltages.

"Electromigration*is the transport of material caused by the gradual movement of the ions in a conductor due to the momentum transfer between conducting electrons and diffusing metal atoms."

http://en.m.wikipedia.org/wiki/Electromigration

To each his own I hope you get your phone set the way you like.

I am not speaking for Andrei, am just hoping to let people in the thread know the risks of pushing cpu volts too far. Cheers happy Valentines day everyone.
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
Overclocking the big cores on this chip is stupid. I already explained that they're running too hot.

Also I set up the maximum voltage limits as they are for a reason. I also think I already explained once here running the little cores above 1500 uses more battery and bring little to no performance benefit.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
Without any UV I have this problem too.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Tauras:
But I don't need anything higher for A57 than 2.1GHz, probably even 2GHz would be enough. I also have no plans to go over 1.5GHz with A53s. I know that higher clock speeds generate more heat but I'm not that ultra heavy user, I just want better overall experience. No worries, I won't go to the max, I'll just stay close to Snapdragon 810 and Exynos 7420 in terms of clock speeds.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
The only one with that clock speed is the Exynos 7420 and it is built in 14nm, even the Snapdragon is clocked at 1'94GHz.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
Okay i see, i am curious what did your asv end up being? See weird thing. before i loaded custom kernel i had that too and it seemed to get super hot on me I am at asv 1 when i loaded this kernel it stopped and then temps got better on undervolt. I think my asv stock volts for something were too high by default. For me the flicker on stock even happened rarely when hot in the normal UI no game at all. Have you tried anything to alleviate the flickering so far. I know in past and still sometimes users recommend use the HWoverlay option in Developer options for flickering in game so to use the gpu more and lean on cpu for rendering less.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Lodix:
I have an asv 5 and it was fine before installing perseus.
[Galaxy Note 4 Q&A, Help & Troubleshooting] Tauras:
I know but I still want to try it. Seemed to work on my Note II. Undervolting also helped a lot. :)
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
Mine is stable for 2ghz at 1237.5mv and 1187.5mv for 1.9ghz. 1.9ghz can throttle pretty easily under load because the first throttle as long as not using full gpu at the same time ie... gaming the throttle is 80c for 1900mhz then another at 85c 90c etc and will start to slow down pretty quick if heat continues to build. 2ghz is feasible but it will give lower performance than the same setup at 1.9ghz because it will take longer for heat to build and the throttling to start. At least in multi thread loads. In a single thread load is the only usage scenario 2ghz may handle just as well as 1.9ghz because there is much less heat on the cpu since it is just one of the big cores. Truly 1.9ghz was a smart mhz to cap this cpu at. 14nm would bring better handling in the future.

Edit (correction): cpu throttles as above only if the gpu is not being utilized over 350MHz. Power consumption is able to throttle as well besides the thermals. Refer to following post by Andrei for more accurate and specific information. I encourage users to read the article posted above by Andrei and Ryan Smith as well.

http://www.anandtech.com/show/8718/the-samsung-galaxy-note-4-exynos-review/11
[Galaxy Note 4 Q&A, Help & Troubleshooting] AndreiLux:
Any game that pushes the GPU over 350MHz puts a hard cap of 1800MHz on the CPU, and down to 1300MHz if over 550MHz. So you don't even reach the situation you describe.
[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
Indeed my misunderstanding just realized that, missed your article link yesterday and just read it after my reply before. Thanks for the heads up. Kind of shocked at the difference in power consumption that you reveal in the article. Excellent article by you and Ryan Smith. I noticed the extreme cap of cpu mhz under gpu load running the usual benchmarks before. I didn't realize power save caps gpu at 350mhz as well or the true extent of how the throttle was implemented under higher gpu loads. Thanks for researching, testing, investigating and finally sharing your results with us in the thread and through the article, including the articles you were involved in previously such as at Anandtech :)

[Galaxy Note 4 Q&A, Help & Troubleshooting] mw86:
The thermal controls for our N910c are designed very well to be honest, I am sure Andrei knows exactly how it is designed and agrees. Try using BOINC and donating some of your cpu time to Science and Biological studies Megax91, use all 8 cores and let it run for a few hours. You will have a new appreciation for the elaborate thermal throttle built in. Having used plenty of Qualcomm chips and had time to compare handling of various chips from both Qualcomm and Samsung, I have found Samsung really knows what they are doing on Exynos and Qualcomm could care less if their cpu under long term load drop to crippling low speeds to survive the heat from their chips. When my cpu hits 80-95c (in this app BOINC for example) I am very happy it finds a fair mhz to use for the load. With my stock voltage which is high for our model over a long term load I'll see a53 [MENTION=4724277]1300[/MENTION]mhz and a57 @ 800MHz -1000MHz and only higher if it is running a smaller workload. With volt controls I can improve the thermals on the same mhz but I would not mess with the thermal controls as they truly are great just as they are.
