[Q] Original ROM's CPU freq scaling range

Hi, just wanted to know what is original HTC's ROM CPU scaling range and what is its CPU governor. My guess is 245-528, ondemand - is that correct?

Sorry, I don't know myself, but I'd like to know this too! I've just installed JokerDroid on mine, and I want to set it to stock frequencies so I can improve the battery life.

I'm using 352-691 ondemand, but I think 748 is ok too.

I think the min is 352MHz. But again, I am not so sure. (I arrived at this value when I was on the Stock ROM and used Android System Info which shows the various CPU frequencies and the time periods they operate on that frequency)

Custom ROM's (Or, more appropriately - Custom Kernels) allow you to set a CPU Speed upto 768MHz.
BUT - The performance increase is not as great as the speed increase shows. So, if you do overclock, don't keep huge expectations.

I am running on 710 max, some people run on 768 max. But apparantly it is phone related because some people can perfectly run on 768 whilst I read a few days ago from a person here whose wildfire started force closing things around 710 or one higher or so.
Try a bit yourself which works for you. There are benchmarks that you can let run to see how often an error will occur approximately I have no link myself but I know a bud of mine did that to try how high he could go

At 691, some apps force closed, so I'm back to 595. It was stable for me.

gues that the 352MHz is the stock minimum then. There should be a noticable battery life increase when 122MHz is my current IDLE clock huh?
Now Iam running 122-710MHz on stock HTC ROM, very stable. If I set the frequency above 710MHz the scaling become unstable uner LOAD sometimes and dropping to 480MHz.

[Q] SetCPU - Extra Info?

Hi there, thinking about getting SetCPU - I have some questions before I do because I hear it can be dangerous?
- I've heard it can brick your phone?
- What if you set it too high?
- Do you personally have to monitor it?
- What are the benefits?
- Use alot of battery?
- Is it really worth using?
- Is it optimized for different phones - example the One X?
Thanks guys!

Hi, i have read that SetCPU cannot view all the cores i have read alot saying that System Tuner works fine you might want to try that.
I used to use SetCPU on my sensation and never hand any issues with it i did not monitor the app at all
Benefits allows overclocking if available in kernel
it can be overclocked and cause some issues such as overheating but if set correctly will be fine doesnt use much battery if any
and no i dont think you can brick your phone
if you set it too high i believe i had to reflash rom nothing major
BTW this is based on my own knowledge and usage
Hope this helps

Thanks man

How much battery life can you save using setCPU?

None in theory, if the CPU is slower it takes longer to go from
idle - process - idle
Faster speeds allow it to get it over and done with faster and get back to idle.
Of course it will at times stop the CPU going higher than it needs too which could save battery.
Under volting will save more batter then underclocking ever will.

undervolting requires your phones kernel to support it, currently on these forums there is only one that does but i haven't tested it, sticking firm to the "stock kernel is best" and will do untill the kernels have more time to mature.
you could limit your max speed to 1 GHz, if you are rooted you can use Core control to turn off cores and run your phone as a dual core.

Not to be lazy, but would running the phone as dual core and limiting it to 1 ghz result in a perceptible battery savings? I'm trying to get a feel for how much I should expect custom ROMs to make my One X perform up to par. Thus far, I've installed two custom ROMs and felt like the improvements were all safely in the minor category.
I did install cyanogenmod 7 on a phone last year wow, that resulted in major benefits.

Running on 2 cores stops the phone from using and 2 cores uses less power then 4, playing games and using all cores is over kill 2 cores will run the game without lag use less power and make less heat.
You'll maybe get 10% from doing that but I haven't tested.
Really the only time any of this saves battery is during demanding programs, tegrea has a super low power companion core, for all your power saving needs.

I tried conservative governor while downloading sd files for Nova3 gave execllent results
I strongly advice not to undervolt tegra3
t3 is not like any other chip and UV or OC should not be attempted
OC because the chip is already at the max of its thermals
UV for the same reason n might end up with problems like flicker
changing governors and UC should be enough

[Q] CPU Frequency suggestions

is it true that over-clocking can damage my phone??
I like it when it's fast enough to play any games but i'm a little worried that OC might damage my phone..
do you have any suggestion about the right minimum and maximum frequency??(sorry 4 my english)

it really depends, im using CM10 on 134-1024 Mhz. Most the games are smooth. Its safe to OC up to 1.4 GHz imo. 1.6 GHz and 1.8 GHz might damage over time and a lot of usage at max frequency

OC is always bad and dangerous, no matter what clocks you use.
Besides, OC doesn't give any major performance boost, you can barely see it.

Why bother overclocking something that is outdated specification wise? And with an single core, the performance boost is non-existant because the core will be driven hard and generate heat and voila.. RIP!

It's not a matter of hearing it from someone. It will definitely happen if you overclock your phone since increasing the maximum frequency from the design limit will fry your phone.

[Q] What is Intelli-plug, MP-decision. Which is best?

Hi guys,
I'm new to android and I just flash a cook rom with custom kernel to my phone.
I use Kernel Tweaker to set some variable to make it use less battery and smoothly but I see an option called Intelli-plug.
I google this and see it complete replacement for MP-decision.
So what is best of them for battery life and performance at cook rom?
(I think MP-decision is best for Stock rom, correct me if I am wrong )

Intelliplug is a replacement for mp decision implemented by faux123 if im not wrong . It determines the behaviour of the cpu and gpu. Stock nexus and OG only have mp decision. Intelliplug is a better option
Sent from my Nexus 4 using XDA Premium HD app

mp-decision is better.
The only thing the Intelliplug do is causing lags, freezes and other annoying strange things.
imho.

There's also msm_mpdecision (not to be confused with the mpdecision binary) by showp1984, which is pretty good. It has input boost and is the smoothest I've tried. I'd give that a shot depending on what kernel you're running. In trickster, it'll be a menu in specific called MSM-MPDECISION control (or something like that). CPUQuiet is supposed to be good as well, but I haven't personally run it. Auto_hotplug and mako_hotplug in faux and matr1x are typically better for battery than others, but are not quite as smooth.

If you are comparing stock vs N4, yes, they are different; stock should actually be a bit better since Qualcomm doesn't include certain things on Nexus devices. On CM, the mpdecision binary used I believe is from N4 4.2.

I don't see anything that is making Qualcomm MP-Decision better than Faux123 custom Intelliplug driver His hotplug driver is everything that MP-Decision is lacking of + more battery friendly and less heat generating..

MPDecision is much more aggressive in terms of changing CPU frequency (automatically goes to 1026 when input is detected). IntelliPlug is more for battery than performance. For performance, I suggest MSM-MPDecision from showp1984 (it's on most of my kernels and a couple others), which performs similarly to the mpdecision binary in terms of boosting frequencies and raw performance, but is customizable. You can change the frequency for input boost or turn it off altogether. There's a bunch of different settings you can play around with.
CPUQuiet also is one of the better performing hotplug drivers. I don't know quite as much about how it works, but it was made by NVidia and ported to Snapdragon by maxwen and has a set of governors which keep the CPU running at optimal frequencies for battery and performance.

In my opinion Intelliplug is extremely finicky and unpredictable. I get much better battery life with mpdecision.

I am a little newbie on this, so may i ask a question?
How can i install MP-decision?
Is it built-in on a kernel or do i have to download it seperately?

any body can completely explain what relay MP-decision and Intelliplug do? or any body know where I can read complete documentation of those?

MPdecision
Guys,
In my humble opinion what i have noticed is - when you enable a mpdecision i.e.on in the cpu, based on your cpu gov settings say for performance - one core of your cpu will always be at 100% and based on the activities it will switch on or off, the other cores.
When your cpu gov settings are interactively managed, again one of your core will be working and based on the certain % say 79 or 80,it will switch on the other cores.
If you deactivate mpdecision then almost all your cores will be active at any given time. But may not run as high as in enabled state.
So if you are one of those who cares about your cpu heating and don't use cpu tuners or sleepers. Set it off.
If you are into gaming and very smooth ui experience and doesn't bother about battery drain, switch it on.
I have enabled the settings and use custimized task scripts to reduce the frequency of the core as soon as i switch off the screen.

Of course it operates at lower voltage as it's a lower frequency and requires less power draw. Lower voltages should mean lower heat, however you don't magically get that lower freqs to operate, you need to tweak the interactive governor to make use of them all efficiently. So far I'm on Kirks kernel and AOSiP and it's a quite good combo.
The lag is not caused by low GPU freqs, it's because of low CPU freqs for that particular load, so governor tweaking is needed.

Lol, I tested what you said out. Because you said it with such confidence...
I changed the cpu governor to performance and set the gpu to 160mhz max...
That made the experience a bit better but it would still lag a lot in recents and app launcher scrolling...
I've attached a screen shot to prove it too...
Another thing, just because the clock is lower does not mean that the voltage is lower as well, many devices that ive owned over the years have had the same voltage's for lower clocks( moto g2, Sony xperia z1)
And lastly, you should "magically" get those lower frequencies(if they are truly unlocked) since governors will always operate within the min/max frequencies that are set by the user or by default(unless it reverts parameters back to stock, like our device does on interactive)...

Forgot screenshot....

First of all, we are talking here about difference in voltage between stock minimum freq for big cluster, which is 1.1ghz and actual possible minimum which is 300mhz, and there is a difference in voltage, that was the point. The devices I owned, S5 and Z3compact had more CPU steps, therefore the difference between some of the steps was really small or there wasn't any, but the CPU scaling made a jump to the freq with bigger difference (higher or lower, that was the stock behavior so some freqs weren't used). Here it might use all of the freq steps as there are less of them and the difference in voltage is significant enough, which might be the case, I said that because of my experience with previous devices. But you've missed the point anyway, I have said that even if unlocked, some freqs won't be used just because they are there if the governor parameters aren't set properly (or will be barely used). That was my point, I said that as a general note, so users won't jump the gun and blame devs for whatever.
And another one, regarding your test and lag with GPU, now I'm confused why would you set your max at 160mhz? I know it was for testing purposes in this case, but you did complain about it in original post and I said it won't lag because the max would still be set to 430mhz in which case the GPU freq scaling would do the job which it does very good so far. It would lag of course if you set max GPU freq to 160, but that's not what would you do for daily usage, right? Sorry if I misunderstood something.

I kinda get what you mean, but the min freqs should kick in by default. They don't though on kirks, you need to change the governor to something like alucard or zzmove once before it actually starts clocking down to 300mhz...
On a side I would just disable the big. Cluster if I could, I don't really need that much cpu performance...
I was trying to find the min gpu freq that would be usable and I was disappointed, cuz my Sony z1 had a smooth ui experience with the gpu clocked at 200mhz max and that thing had a sd800...
Btw, I do all this to get better battery life...

I found out something else, I can't use power save governor any more because it can't handle audio processing(ainur, v4a) when the screen is off...
Just like my old z1, Lol...
Makes me think that the performance is really identical to the snapdragon 800...
I wonder how pissed I would be if a I got the redmi 5 plus, the 625 would have been even worse...

Yeah I agree, it should, but how much it stays on minimum freq is dependent on couple of governor parameters (talking about interactive). On mine though it does stay on 300mhz when idling, on stock Kirks settings. Big cluster can be disabled through new hotplug solution, like Intelliplug, which I used on my old devices, and it performed great, 1 core was active when screen was off, screen on and light usage required only 2 cores, while all 4 were active under heavy load. Here however there is only Qualcomm's hotplug solution, until that changes, no luck. Regarding GPU freq, I don't think any device would work smoothly under 200mhz, you can set 266mhz here, it will be smooth, I've tested today, on my old SD801 it performed at 233mhz IIRC.
I've seen that, V4A requires higher freq than 300mhz, or even 422mhz which SD801 had, it's more about the freq rather than the chipset, as I've read on multiple threads that even the devices with SD820 were struggling a lot when processing audio at 300mhz when the screen was off. Don't worry, it's a general issue. There is also the optimization of the rom and audio mods as well, background tasks, kernel, it all goes into the mix.
This is actually a very good chipset, it's technically SD660 just with lower clocks on both CPU and GPU.
EDIT: I forgot, this is my usage on AOSiP + Kirks, stock interactive tunables, min freq 300mhz (big/little), GPU initial/min freq 160mhz, max 430mhz. Using microG instead off GApps, I have used FB, Instagram, Messenger app for 1,5h each, Viber was couple of hours, Chrome some 30mins, Panini sticker album 30+ minutes, 30 minutes of 2G calls. Network mode was LTE, though I was on wifi on whole charge.
Started measuring from 92%.

Thanks bro, that explains a lot...
