Hi all, I'm facuarmo (Facundo Montero), the person behind SomeFeaK. I would simply like to know if someone is interested on the release of a public version of the SomeFeaK kernel with some experimental features that might be harmful and dangerous for the device, I know some people simply buys devices to test them and kill 'em ASAP, and I thought they might have some fun with this.
Some of the features include:
- CPU: up to 2.11 GHz.
- GPU: up to 750 MHz.
Please post your opinion here.
Hi friend, my opinion is that even if you manage to reach those frequencies in a stable way, you will not achieve higher performance.
Overclocking is only useful if stability and performance are achieved.
To achieve higher frequencies and higher performance, higher voltage is needed.
As the voltage and frequency increases, the temperature increases, so a better cooling system is needed, otherwise overclocking is useless.
I think the most you can achieve with the stock voltage is CPU 1400 mhz and GPU 450 mhz, you have to check Qualcomm specifications.
Greetings.
I'll definitely give it a test.
This is my second device, my main is a Pixel XL so don't really care what happens to it unless it doesn't explode and kill me or it catches fire and burns me?

hi, is there any way to overclock the processor on the xperia?
By over clocking do you mean take the Xperia beyond its theoretical headline Limit of 528 mhz ?
I have looked at this but the new processor does not seem to be supported by many of the commercial solutions avaliable.
However SpeedBooster posted on the Turbo Speed X1 thread, allows you to set higher processor priority for the programs you choose, giving them a larger slice of the processor pie, its not overclocking as such, but it does make the processor work faster for the programs you choose.
I have used it for a few days with no serious problems, howvere having the processor running faster will drain battery faster, I have noticed this, but it is within acceptable limits for my needs,
I prefer the extra performance over the extra miliage.
Can you do a benchmark and post the results?
Would help a lot to start making a comparison between devices.
Is this what you're looking for:
Hi all guys! I have a couple of questions and would like to hear some experiences and thoughts in general about overclocking in Android.
First a couple of more specific questions which I would like to have answered, if possible. If it's not possible, please give me your general thoughts anyway about overclock instead of moving to the next thread, please.
- Are there any kernels which allow overclocking beyond 1536 MHz?
- If so, did anybody try those frequencies? What was the result?
- Are there any people who for some reasons did NOT manage to have stable 1536 MHz?
- Are there any reliable reports of people frying their phones due to overclocking?
- Are there any easy ways to undervolt the CPU (at standard frequencies, not overclocked) in order to save some battery charge?
My very little OC experience is based on this: I have been running for some days a ROM based on a kernel which allowed OC up to 1536 MHz. I installed CPU Master Free, did some tests and found out, to my surprise, that the phone will run @1536 MHz without any noticeable issues. I never kept it at that frequency for more than 5 minutes I think, because I was afraid of excessive heat, but the phone never got really hot, just a bit warm. I ran some system benchmarks (Quadrant and another one which I can't recall right now) which stressed a bit the CPU and did not encounter any crashes. I also did this with performance governor which keeps the CPU constantly to the max frequency I think, and still no probs. Since everything works so fine and was that easy, I was wondering why don't everybody always run with the HD2 @1536 MHz. Is it only for battery issues? Please share your ideas about this and OC on the HD2 under Android in general.
Thanks.
The problem with overclocking isn't just overheating or too much power. With overclocking you are also increasing the say, amount of data being passed through the cpu. If the cpu's bus size isn't fast or big enough to handle it, it will ultimately slow down or malfunction.
So you should get the picture of overclocking now. Note however there are some safe speeds for overclocking.
Onto your next question as to why everyone doesn't overclock to the max speed. The reasons are: paranoia and safety of device
You have to know that not every chip is made exactly the same, they are modeled after the same design but are never made the same. So that mean whilst some people's phones may be able to handle extreme overclocking, like yours, others may not be able to, and malfunction/overheat. Malfunctioning like, cannot make phone calls, wifi/GPS doesn't work, etc.
So I hope this was informative.
Not everything you have said was new to me, but you were informative.
...although I would really be surprised to have issues with phone calls for instance caused by excessive overclocking...
Do you personally keep the HD2 overclocked?
Anybody else?
When I had my HD2, I rarely did so. Reason being is that I found no need to. The only times I did do so was to see if the phone actually was faster. In my results however I found no big difference so I didn't bother.
Well, the phone is indeed fast without OC, but you can feel the difference if you are performing some CPU intensive tasks. For example, unzipping a 200 MB ROM archive, or importing 1300 SMS from a backup. A temporary OC can save you maybe 1 minute or 30 secs, which aren't absolutely worth the time you spend learning to overclock the device, but never mind, even if you only saved 5 secs it's worth it for the satisfaction.
Ah I see your point. I was only looking in the perspective of simply tasks such as browsing internet/market, games, gallery.
Figure it this way. When you overclock a pc, (and if you're doing it safely/correctly) you have usually spent extra money on liquid cooling systems. Or at the very least, bigger fans, bigger heatsyncs, etc. Even with all that, you could very easily blow out a cpu or other component when you overclock.
Now, on a cell phone, you're running a MUCH higher risk. First off, there is NO extra cooling, and considering the size of our phones, and how thing they are, there's really no room for airflow. So while yes, it may work for you, in general I always say getting those couple extra frames per second out of your game are not worth the potential damage to the device.
Overclocking on actual computers has gotten much safer in the last few years, because the chip designers are putting more effort into keeping the chip cooler under load. Cell phones are not designed to overclock (even one as sweet as the hd2.)
Lastly, when overclocking a system (desktop), you usually change more than just the cpu clock speed. You'll usually have to adjust the voltage to compensate, and in some cases adjust memory timing as well as bus speed. None of this happens when you overclock on the hd2, all you do is change the clock speed.
It's not set in stone, but there's a very real possibility that you can do permanent damage to your device when overclocking. And, you may not notice the damage right away. Also keep in mind, these are mass produced cpu's, and there are slight variations in each chip. (Hence why some people can overclock higher and keep stability, while some phones with the same chip get picky if you even overclock 10mhz )
I've never seen the point in overclocking the hd2, you really don't get any real world speed out of it, it's a placebo at best. (And please don't start showing me or quoting benchmarks, they're useless, and extremely easy to make little changes in the roms to artificially boost benchmark scores.)

Great info mstrk242,
Thank you!
All benchmark info is skewed. Tried 1500mhz and the only app I noticed a difference on was gun bros. A new more efficient version of rom made it run fine at 998mhz. Not worth the extra wear and tear on your device. Simply changing things like your launcher can have larger effects.

hi guys i just want to know what is the max overclock of the cpu and the gpu for the nexus 7 ( please has to be has safe as possible, i dont want to damage the tablet too much, and yes i know that overcloking will reduce the life of the tablet) I want to get the best performance out of this tablet!!!!!
Note: battery drain is not a problem!!! I will use the nexus 7 for gaming most of the time and also browsing!!!
Please I really want to know i created an account on this site for this!!!
Most people can go to 1600 on the CPU. Any real world performance increase from the stock 1300 is negligible.
I wouldn't overclock the GPU past 446 (+30) because anything higher creates a lot of heat and people have reported benchmarks actually being lower once you go much higher than that.

Hi, tbh you'll probably not notice much if you overclock the cpu to 1.6ghz as percentage wise it isn't a large jump. Things may feel a little zippy at times though, in my house I have acces to two n7's, one stock and one overclockable to 1.6ghz. Ran tests between them and the 1.6ghz was fractionally faster, the difference was very small. Overclocking the gpu to 600mhz vs 416mhz at stock made a huge difference, as it it made some games actually playable. Despite the crap Nivida spit out about the tega 3 soc, it's GPU is comparatively weak. Over-clocking the GPU will give immediate performance increase in a lot of games. After doing heat and clock speed tests myself, I've found anything in-between 416-600mhz to give near enough liner performance increase and heat to be long term sustainable depending on the voltages your device can handle. Overall, I doubt CPU overclocking will give you much benifit, but if you play games the gpu overclock will. If your worried about heat from overclocking the gpu a lot, you can always use this kernel http://forum.xda-developers.com/showthread.php?t=1937146, which gives you full GPU clock and voltage control so you can undervolt your gpu to reduce heat. I wouldn't run at 600mhz unless I could undervolt the gpu as much as I have and I use that kernel because of it. I have my gpu overclocked to 600mhz running at 1225mV, which is only +25mV above stock voltage for 416mhz. Although most heat is generated from the transition period of the transistor charging/ discharging, undervoting does give a large positive effect on heat output if it's large enough. But 600mhz is a high GPU clock and the highest I'd recommend, tbh I would say 520mhz is a really good compromise between heat, performance and battery, especially if you under-volt the GPU at that frequency for most people if your not as annal with FPS as I am :silly:
Thanks Too

AW: Nexus 7 Overcloking
You all probably have seen those 2GHz oc screenshots.Are those real?I'm not wanting to try this I'm just curious.
Sent from my Nexus 7 using xda premium
They are probably real
yes i have almost sure they are real, but puting the nexus 7 in 2Ghz will, i think will damage a lot the tablet!!!
The 2 GHz kernel was a test to see how far the Nexus 7 could be pushed. This kernel wasn't released for obvious reasons so yes, those pics/ benchmarks were true.
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.
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"
