I want to raise question is it possible to overclock the CPU, or GPU or memory speed. We all know that ze550kl / z00l performance with msm8916. Is almost in the limit to run apps and games, wanted to know if possible or not, and if there is any development has this respect. I like the device and it is great but it is clear that it is getting weak in the matter of hardware, if someone can work in this respect to give a breath / power to our device

i don't think so , if its possible to overclock the processor to its frequency,
you can costumize it too max frequency of it or to lower , as u need
But if is then i would love like to know too
I am already extracting the maximum, from him that I can of him, already put using ex kernel, with governor ordenad, frequency of 200mhz @ 12000mhz, and simple GPU ordered frequency of 200mhz to 400mhz, active zram of 512mb, and entropy of 128/256, then Of course, here with standard frequency of the paddle extracting nothing more than that, the problem and that we have a large bottleneck in memory lpddr3 of 533mhz, that opera and 32bit, there is a single channel giving bandwidth of 4.2gb / s that It has to be split between CPU and GPU. What is clearly one of the pro soc power limiter, I do not know much about the arm architecture, but I can not do over clock in lpddr3 memory, since I did not see any software or tutoring Citing this. Although this would be a solution, if you do over clock in the CPU or ns GPU will force the clock controller up what will increase the memory performance consequently, something else, not good will lock the clock at maximum in 1200mhz and GPU at 400mhz, as there will be a large power consumption and the performance will be limited by the cords of the tempering control and the low frequency of the RAM, # excuse me to have been so far more enthusiastic about hardware,
even with my old htc explorer i could increase cpu clocsk from 600mhz to 900mhz why we cant do it on zenfone 2 just we need good developer and kernel
it's up to the hardware
If you look at the specs from qualcom it has a max speed and not every device is possible to reach the max, but if you have the proper kernel you can reach that speed and "overclock"

so now that the latest beta of siyah kernel supports enabling/disabling of the 2nd core, and tegrak already released an app for it, i just want to know the possible effects in performance/battery if you use the different options of the 2nd core app.. especially when we use the single core option.. so what will happen to our phone when we run HD games, and im sure that it will extend the battery life, just not sure how the phone will behave with only 1 core running.. and will it be bad for our phone to only run at a single core..
and also, am i right to assume that our phone has the option "dynamic hotplug" by default?
Shouldn't see much of a decrease in the performance. The sgs has a single core yet the cpu can still handle anything thrown against it. Point being there is nothing out that demands dual core performance. On another note note, hd games are not actually gd. It is just advertising point for game developers.
$1 gets you a reply
Using one core instead won't break your cpu. It gonna make your phone cooler ( ! core is running producing less heat and the heat dissipator is made for the dual core ) and have a better battery life obviously. It will, obviously too, slow down your phone, but the speed lost is to be determined. You might want to test it out to see if it's getting laggy or simply suck. As already said, the SGS I has a 1Ghz proc and can handle most of the top recent content available so with a 1.2 Ghz single core, you should be able to handle everything available, specially with an optimized kernel like siyah. And you are right, the default mode is dynamic hotplug, which use both core when needed and turn the core 1 ( 2nd core ) off when not needed.
I tried playing a little with it. The overall smootness doesn't change and i get about the same fps in nenamark2. The only game i saw stuttering a little more in single mode was Shadowgun, the others are just the same. I also have the feeling that cpu noise is reduced while playing music through headsets when you run on single.
I like the idea of switching off one core. But while using only one core this leads to a higher load on that corse. This will result in higher frequencies an thus higher battery consumption?
So might using only one core even be worse for battery life?
I mean isn't that the reason why you use multiple cores? That one does not have to produce cpu with high frequencies? I think I once read that the energy a cpu uses it proportional to the frequency squared. So it is not a linear relation. That means two cores on 500 MHz are using less power than one cpu on 1000 Mhz. Can someone confirm that? So if th os is optimized for multiple cores the energy consumptions will be less.
What do you think or know about Android. Is it managing two cores intelligently an thus reducing energy consumption or are we doing better with switching off one core?
Hi,
is anybody out there who can share any experiences with this 2nd Core app?
It would be very interesting whether it really saves battery(and if yes, is it noticeably or is it a huge difference)? Are there any negative effects in speed oder stability?
Rgds
I don't particularly care about potential battery saving, but I use it to manually disable one core while playing games which have problems with SoundPool ( see http://code.google.com/p/android/issues/detail?id=17623 ), such as Galcon, as this mitigates the problems.

totlly agree
Does anyone who has looked at the kernel source know if we will be able to do RAM overclocking? We know from the whitepaper that playing games on the resolution that the N10 has will take 10+ gigabytes per second of bandwidth so a memory OC should be able to help out considerably, especially if overclocking the GPU as well.
Additionally, how come we never see an area in the tunables where we can tweak timings? All we ever see is voltage and frequency, but the memory has to have primary and subtimings as well, just like all regular computer memory. If someone could make the timings able to be modified we might be able to get some series bandwidth increases out of these.
Oh and one last thing, why dont we ever see memory voltage setting either? We have core, gpu, and video decoding core voltages but being able to tweak memory voltage would be a great addition too. We already know that the Exynos 5 dual uses low power 1.35v DDR3 memory. If Samsung's other LP 1.35v DDR3 chips are any indication, these things have MASSIVE overclock potential. I have seen people running them up over 2400MHz!
bump since we have device support now. Any kernels dev's want to look into the possibility of these things?
I too would be very interested in seeing some RAM overclocking/voltage tweaking; I believe it could open up a lot of potential
If a kernel gets developed that can accomplish this I'll go to the store and buy a n10 that very same day.
Right now I'll show patience and wait to read true reviews from actual users.

I'm not overclocking my device, in fact if anything i'll under volt it. If I could get a 3rd party accidental warranty, it would be a whole different story.
I've been using XBMC on the FireTV fairly successfully but wished it was a bit snappier. Thinking back to my days with the Galaxy S3, I remembered a great app called Seeder.
From the Play Store listing:
Seeder is a service for root users. It assists the kernel in "topping off" the entropy pool by re-seeding it with data from the non-blocking (high performance) random device. Optionally, it can also help alleviate MMC I/O contention by extending the I/O queue, allowing the I/O scheduler to make better decisions, and combine more writes.
After installing and enabling the moderate option on my FireTV, XBMC loads faster and navigates through menus much smoother. An essential app and well worth the purchase in my opinion.
Setup:
Root your FireTV (http://forum.xda-developers.com/showthread.php?t=2783805)
Install Google Play Store (http://www.aftvnews.com/how-to-install-the-google-play-store-on-the-amazon-fire-tv/)
Download Seeder (https://play.google.com/store/apps/details?id=com.lcis.seeder&hl=en)
Give Seeder root permissions
Select Start on Boot
Choose Moderate
Profit!
Seeder ($2.50) - https://play.google.com/store/apps/details?id=com.lcis.seeder&hl=en
Thanks for your tip. Does Anyone else recommends it? I am quite satisfied with the firetv performance but i am all forward with improvements

It does boost performance,even with my "overclocked" settings already made.
I quote it because I can't actually overclock the Fire TV because the lack of unlocked bootloader.
I can only change governor types to "Performance" on GPU,and "interactive" on all four CPU cores to boost them a bit.
I also have two booster apps for visual and touch performance increases,which prove to work really well.
I want to OC the GPU to a minimum 400Mhz and maximum 500Mhz to match the stronger equivalent GPU's 450Mhz and 550Mhz OC settings.
Maybe also get the CPUs on at least 1.9 Ghz or 2.0Ghz as the maximum with 500Mhz as the forced minimum.
When bootloader unlocking is possible,I want to find a fix for the kernel panic rebooting issue with Reicast caused by instability with certain Android ROMs.

Nothing...NOTHING about what you're doing is even remotely considered overclocking....
OC is pushing hardware past it's max performance out of the box or standard state. CPU's downclock themselves for power savings. You telling it to run at a different minimum isn't OC'ing, you're just telling it to not downclock itself so far.

Lighten up. In case you missed it he said he can't overclock and even pointed out his use of quotes.
If you want to be nit picky overclocking is not pushing hardware past it's max performance but TO it. Overclocking takes the hardware past factory spec, which you could call "standard state" but that is never near the max. It is set for stability and longevity not necessarily the fastest performance.
Intel used to push a new chip until it crashed then dropped it a notch and called it XGHz. It's why overclocking was so limited without changing voltage and needing extra and even extreme cooling. AMD always designed a chip to have plenty of room to grow and why they support overclocking and enabling extra cores.
AMD now has some extremely powerful multicore CPU processors up to 5.0Ghz!
It's called AMD FX-9590.
Beat that,intel!
Confirmed. . Seeder 2.0 actually does speed up the just about everything from watching streaming movies to using XBMC, except your Internet. . Highly recommended. Use the setting above and trickster mod.

intel destroys amd! and thats a fact! a 4.4 ghz i7 would still beat that 5 ghz amd in benchmarks! so its already been done

Not to go further off topic but benchmarks mean literally squat VS real world use.
According to the review of Anandtech, the Mali T760 GPU on our Galaxy S6 has a unused 852 Mhz clock state. Normal speed now is 772 Mhz. Hopefully, this can be enabled in future in custom kernels to better drive those 2k displays. I wonder why they didn't enable it default as the SoC on 14nm should handle the temperature. More speed Ahead i hope.
"There's also a suspicion that Samsung was ready to go higher to compete with other vendors though, as we can see evidence of an 852 MHz clock state that is unused. Unfortunately deeply testing this SoC isn’t possible at this time as doing so would require disassembling the phone"

That's cool! Maybe they didn't enable it to safe battery?

Perhaps, with custom kernel we can maybe turn off 2 A57 cores and ramp up to MAX GPU 852 Mhz, that'll be sweet.
Actually the test on the battery page proved that the GPU is throtteling when it targets the maxium frequency
"The one major issue here that is visible from the FPS vs time graph is that Samsung continues to struggle with graceful throttling as the GPU attempts to always target maximum performance, which causes a strong rise and fall in frame rate as the GPU goes through periods of high and low clock speeds determined by the thermal governor."

I think this only happens on sustained push by the benchmark app, i doubt it'll be same behaviour on real world usage. But in any case custom kernels will provide various tweaks and alternative governors to try.
They have also hidden 4 frequencies on the larger cores. They are at 2.2 even though they can go up to 2.5.

DVFS is sadly in effect all the time limiting the frequency. You can check it yourself by opening CPU-Z in multiwindow (only way to display frequency of the mali gpu) and running a game. Only thing that is going to let users run customised settings is xposed with DVFS disabler + custom kernel.
ok so as we know the xt has a Qualcomm snapdragon 616 cpu, the GPU frequency is 550mhz as max but everytime i see the stats it stays locked at 400mhz no matter what you task you do. Is there a way to override the frequency lock and make it reach 550mhz?? i think that would make the phone feel smoother and handle intensive tasks even better. Hope i get an answer soon.
