i m on v10D, i just rooted and intalled setcpu, 1500 max 1400 min gov: performance, now just after i restart/turn on my device, the frequency is right..but then after a couple of minutes it drops to 1000 mhz..i have 2 questions:1.is there a way to fix this,2.does any other version( other than v10D )offer better gaming experience...and if so, which is the best?
Thanks for your time :good:
Well i have mine when I game set to 1500 low and high plus performance. It never drops and other then that. One issue I did encounter is that as long u have profiles set up and checked it will still use them regardless if u set it in the front page to a certain speed. So u need to uncheck all profiles and also uncheck the use profiles. Basically uncheck it all then even if u uncheck use profile it still will use the profile if u select one. Here a picture from what I mean. See how I unchecked everything. U need to do this to or it still will the profiles even if not checked the use profile box.

not that i know of..i had lg gear box but i removed it...i also have ATP tweak but i dont think that s relevant
Edit: i just removed the atp tweak..and it still automatically returns to 1000mhz
btw, are you facing any lags, framedrops, etc on v10F?
and is there any way to force the 4 cores to work simultaneously?
I have the same problem. When i set frequencies to 1500 min and max in game it's still change to lower.
I don't really know. Mine always stays steady on 1500

My problem is same as you. I don't rooted my phone.
I have stock v10h firmware hungarian,
When I play games, all games very laggy.
I checked the CPU speeds, the max frequency is 1300Mhz and below.

that 's 3 people with the same problem...and no one is helping -.-, ^^^and he 's on v10H so its not fixed by update .-.
anyone??
It didn't change anything for me to put the CPU @ 1,5GHz constantly. I did a test with the game Horn and its lagging exactly as with the default CPU governor enabled.
If you think about it for a moment, it makes sense, as the GPU is doing the majority of work.
Tegra 3 CPU Clocks
Based on what I understand about Tegra 3 from this thread- http://forum.xda-developers.com/showthread.php?t=1664391, the CPU has 3 different "modes". 1.5Ghz single core, 1.4Ghz dual and triple core, and 1.2Ghz quad core (At a certain temperature, remains on 1.4Ghz or 1.3Ghz until that temperature is reached... quickly). The reason why the frequencies go down is because when the phone is utilising more cores, the frequency drops too. The move from 1.5Ghz to 1.4Ghz causes lag in games at times, which is why the maximum should be set to 1.4Ghz to prevent this from occuring. Also they said that the performance governor causes 2 of the 4 cores to no longer be in use, which is NOT good for Tegra games such as ShadowGun as all 4 cores cannot be used, so they advised people only to use it for Non-Tegra games as they do not use all the cores. Hoped I helped in any way, even though I'm a new guy. I'm not sure if this applies for ALL Tegra 3 devices or just the HTC One X, but it still looks like useful information.

Thanks for your reply..but for me, the frequency doesnt drop to any of the values above, it automatically drops to1000 and mostly its on 1 core
Which brings me to another problem...i need a way to force the activation of the 4 cores simultaneously...in most games the cpu is stuck at 100% single or dual core

Most games are not optimised to use 4 cores, so I guess using only 1 or 2 cores should be normal. What governor are you using for games, because this might have an effect on the performance.

I tried all governors..performance isnt the best, idk why..userspace seems to work fine, but still when i set min and max freq above 1000mhz, it automatically drops to 1000mhz ._. and that isnt quite good for gaming, and since i bought this device over s3 for gaming, i feel f*cked
so would an update to v10F or a hard reset fix anything??
EDIT: and there 's 4 other people with the same problem and one of them has v10F so hardware problem??if so, im hanging myself

@senci00: your brother is joking only with 1000MHz
@fotak-x: no, you can set higher frequencies than 864 with a modded frequency table. I made an experiment earlier and reach 921,6MHz, but:
-the phone was really unstable
-needed really cold environment (around zero celsius)
-to reach this frequency needed to extremely decrease all other frequency (axi and ahb bus), so the phone was slower
@Gogeta: basically the arm core can't produce enough heat to get physical damages due the overheating (the most critical part is the soldering what need around 280C temperature to damage, hard to reach it with 1-1,3 voltage and 100-200mA)

Theoretically yes, you can set high frequencies with minimal risk. All arm cpu have extreme low power consumption (compared to the x86 cpus), the physical damage due the heat is minimal (but more than zero) The overclock ability of each 7x27 soc is different and depends on lot of thing (damages in the silicium structure, soldering quality between the core and the case, etc...). Some soc unstable on 700MHz, some working good on 800+ MHz. And the most x8 owner have "low quality" cpu, because under the manufacturing procedure all cpu tested, and the high quality cpus (what stable on 800-900MHz) marked and sold as 7x27T (turbo) with default 800MHz (this is normal, usually the manufacturers sold the damaged cpus with lower clock or disabled features, for example: you buy an i3 cpu into your desktop, but maybe the cpu manufactured as i5 with damaged core, and after disabling the damaged parts, sold as i3).

I've always been a big fan of undervolting. These are the lowest voltages I can get stable at these common speeds. I found I can underclock the Matr1x kernel further than some others I have tried for some unknown reason. How low have you been able to go? Also, what programs do you use to test stability? So far, I have been running Antutu test completion as a measure of stability. Any suggestions otherwise?

To increase battery life,
The Long answer is that the CPU has a number of parameters where Clockspeed (MHz) and voltage (mV) are two. Clockspeed, well that is speed. Voltage is related to the amount of energy provided to the cpu, undervolting means that you feed the CPU less juice but demand that it runs at the same clocks. You are essentially starving the CPU,it uses less energy, but can become unstable if the voltage is insufficient to maintain operations. Manufactures always have extra voltage as a safety margin so power users can check their CPU bin (slow, normal, fast or faster) and lower voltages step by step until they crash the phone during a stress test, increase the voltage slightly and boom, your phone uses less battery power while being just as fast.
I undervolt to reduce heat. It makes a significant difference. The battery saving is minimal, but the temperature difference is VERY noticeable.

Took words from my mouth. This this and this. It reduces heat, which in turn reduces battery use. UV by itself doesn't save a lot of battery, it's the consequences of it. I'm normally not a fan of UV, but with current N4 sw/fw it NEEDS it. It's way too high.
Interesting observation. As of recently my phone jumps up by 3-5c from 37-38 hover. Never used to do it before, not until i got it up to 50c for about half an hour last week. Previously it would stay steadily at 37-38, now it spikes up now and again during use. What's interesting about is that once it goes over 40c battery use increases drastically. So i wonder if people that have really good battery life don't have phones that go over that temp often and vice versa.
I haven't played around with the values too much yet, just a -100mV across the board. This seems to work just fine, so I might experiment some more..
Using Franco test-r69 at the moment.

I undervolt to prevent heating like others say. My Antutu scores drop like a rock when I'm at stock clockspeeds mostly likely due to thermal throttling. Now I can run it repeatedly without having scores drop. It saves battery and runs faster while running games even for very short periods of time, so I am a big fan of undervolting. :good:
Undervolt to reduce power usage, think of the stock voltage as normally being more than is required, think of running for a bus yet you have 2 minutes why waste energy when you can walk and still make it .
Undervolt for less power usage and less heat produced meaning battery performance is better (cooler battery is a more efficient one) and performance is up as you avoid any thermal limits in place .
Great stuff undervolting, I have managed to get -150mV across the board ( 1.5ghz @ 1000mV) and 288mhz is 162.5mV .
I came from a nexus s ... And one member of xda went to amazing lengths to show that undervolting really made very little differences in battery life ... And it def wasn't worth the instability .
He did loads of tests and I mean loads and basically showed that in helped so little that if you had a reboot you would use more power in rebooting then saving via undervolt
However . it is worth it for the heat decrease for sure

The more the heat, the faster the battery drains. Since undervolting decreases heat, im sure it should increase battery life. Maybe not for browsing or calling, but playing a heavy 3D game.
is it normal that the higher the frequency the lower the voltage in setcpu?

Former nexus s user here, the reason nexus s didn't benefit in battery life much was that it only had 1 core, and used a higher nm manufacturing process, 65nm -> 28nm. Lower voltages in the 28nm means that it multiplies the heat/power savings more than a 65nm, and the 4 cores multiply the savings by up to 4.

I am using Carbon ROM 4.3 with Chronic kernal. The settings were at a min of ~1700mhz and a max of ~2200mhz. Before i set this I let the cpu temp cool to about 23 degrees Celsius. I then set the cpu governor to performance. Then I started running AnTuTu benchmark ver4. After the cpu integer test the cpu froze up. I was cooling my phone using a freezer with the phone on a paper towel which was on a bag of ice. The CPU crashed at the CPU float point test.
After another test I found that my CPU becomes unstable after 2160mhz.
The settings for the posted benchmark were CPU Min at 1674mhz and CPU Max at 2160mhz with the governor set at performance.
The minimum freq is mute when the gov is performance. Performance just keeps the cpu at the MAX freq.

I am aware of this. I did have it in the freezer until it cooled down enough. The problem was not overheating, it was the CPU becoming unstable at full load with the processor being overclocked. The phone was still cold but it went to a reboot or just turned off.

Ok buddy here is your issue buddy its all about volts and throttle limits ive been fine tuning oc steps on antutu, cf bench, geekbench2 and geekbench3. Im stable all the way up to 2106 so far I use ktoonzs kernel cuz it has more options in his app the control alot of the throttling and volts. Ok understanding what it means what the phone just shuts off or reboots when the phone shuts off and wont cut back on you either have to do pull the battery out or plug the charger in to get the phone to boot up that means you had a power overload it drawed to much power on the battery which means you neesd to drop volts on your max step. Now if the phone is just rebooting or if the app FC back to the home screen that means that you dont have enough volts for your max step you only have to add or substract volts on that one step not on the whole board the best way to do this is just by finding your volts for that max step first yes scores will be low but once you find the volts then you start adjusting the throttle limits that way you can control the heat of the cpu but once you find the sweet spot of that oc step move to the next one and start over again for the next oc step doing the steps I listed above I will post pics of what I gotten so far. On a further note I have found that the freezer trick hurts you more then gaining anything cuz if you cool the cpu and battery to much it will make the cpu run sluggish cuz its to cold to run and if the battery is to cold it makes the phone think it dont have enough power to run on that oc step and makes the phone reboot so bare in mine the freezer isnt always the best way to do this I found that if the battery is below 28c it will reboot the phone during benching and if the cpu is below 25c it sluggish as hell the best app to use is cool tool on the app store if you use kt kernel I can give you the direct path to monitor cpu temp like his app does hope this helps you understand alil better of whats going on if you need anymore info just pm me

Hi,
I saw BravoMotolora's article about CPU binning, and I thought that it would be great if we compare CPU bin and voltages.
It will be great to know the relationship between voltage and PVS number.
Please follow this procedure
1. Install a custom kernel that lets you do undervolt, e.g. franco.Kernel
2. Do what BravoMotolora said
3. Undervolt your N5 by 25MV
4. Run Antutu
Then, you might see your N5 rebooting or giving you a Antutu score.
If you get the score, go and try the procedure again
I got to -50MV with PVS1 N5.
Please post your results(undervolt that you did and your N5's PVS) here!
Can you not do this?
Do not do what? I mean most of guys here will do undervolt to save battery anyway so won't it be good to share some intel?
Sent from my Nexus 5 using XDA Premium HD app
I'm the same as OP... I have PVS 1 and the max I can UV is -50mV.
you do realize that many custom kernels set their voltages different than default/stock, and differ among themselves? for example, if you go -50mV less on using franco kernel, and go -50mV less using trinity kernel, it means nothing because their voltages differ to begin with. i mean you cant really compare each others voltages that way. you would need to write your voltages in real numbers, and cpu speed steps.
I honestly never saw a huge benefit in undervolting. It can also cause errors which lead to worse battery life.

it's a lot easier to underclock 20% than to undervolt 10%, which approx. gives you the same active power savings. It's a lot safer too, if you don't have a spec sheet for the CPU handy.
underclocking does nothing to idle power (or leakage power) though
This phone does pretty well arlt idle I think. Can't imagine you would see much gain from UV.

Underclocking drops the performance of the phone, as the peak performance is not available when needed. Undervolting on the other hand gives you battery savings without affecting peak performance at all. If done too aggressively, it can make the phone unstable, but there is never any danger of hardware damage. The instability will at most cause errors, random reboot, or a freeze up. If this happens, you know you've pushed too far under, and you can bump voltage closer to stock after booting the phone back up. If running stably, undervolting is actually marginally better for your phone hardware than stock voltage because you are wasting less of the energy in heating up the chips and damaging them.

i underclock, sometimes to 1036mhz max, with all 4 cores always on by default(no hotplugging). sure, in a benchmark itll score less, just like i expect to score more when im overclocked. but to the normal user, they would never be able to tell that my phone is only clocked to 1036mhz. meaning the user experience isnt lowered in any way. even intense gpu oriented games dont show that im running underclocked. so when you say it drops the performance, it isnt entirely accurate.

Sorry, but CPU underclocking means always a drop in CPU performance.
When you compensate this drop in your case by always having all four cores active you produce more heat with the active cores.
(and I estimate it will produce more heat/battery depletion than the original phone settings. (max 2,26Ghz and variable core usage)
When you argue that in general a normal user is not realizing a drop in performance due to underclocking...fine.
But it will always be a drop in performance.
Undervolting in opposite to underclocking produces no drop in performance but actually a rise in efficiency. (and thats what CPU/GPU development is all about).
Less heat, less battery depletion, same performance.
Why not taking advantage of that by undervolting?
Its free lunch.

i underclock, sometimes to 1036mhz max, with all 4 cores always on by default(no hotplugging). sure, in a benchmark itll score less, just like i expect to score more when im overclocked. but to the normal user, they would never be able to tell that my phone is only clocked to 1036mhz. meaning the user experience isnt lowered in any way. even intense gpu oriented games dont show that im running underclocked. so when you say it drops the performance, it isnt entirely accurate.

I agree with you here. 1036 mhz is a great CPU speed for running the device and most apps. Most games UC the CPU for better battery temp like in PPSSPP. Less temperature throttle and more stable frames per second.
Benchmarks are a difference story though but who cares about those. UC is lag free, and buttery smooth so why not?

again, sure, if youre benchmarking the performance will drop, yes. but if its something that the user doesnt see or feel, then its irrelevant.
no extra heat is produced. also, i get 5.5-7h screen on time with very heavy use. granted, i use the browser much more than i game, but thats what i use my device for mostly.
when needing the extra performance, or wanting to, i overclock. everybody uses their device differently, has differing needs. i would never say one way is better or worse than the other way.

You can do everything you are already doing, but also undervolt, and your battery life will increase, without affecting your performance. Your performance will be different than my performance (because I don't underclock), however imperceptible as it may be. So undervolting is still better than not undervolting, even for you.
Using EX kernel 3.27, underclocked to 1.5Ghz, undervolted to "700 min" and using "stock" thermal throttling setting. Rock solid and it barely even gets warm now. Responsiveness and performance is only a touch worse than stock; the only places I really notice any performance reduction is in intensive games and app install times. Battery life is massively improved.
