Hi.
I have used CPU Info and CPU gauge to monitor the CPU usage of.my phone. Both these apps display my processor as having a speed of 681.57 MHz. I hope that is not true. Any idea why they say so ?
Ps: which is the best app to monitor my CPU ?
Sent from my Desire HD using XDA App
That sounds right. Even though the phone has a 1Ghz CPU, by default, it doesn't run at 1Ghz all the time. This is to save battery charge as the CPU throttles the speed depending on load. If you put it under full load it will go to 1Ghz for sure. I think when device is in standby it runs at around 200MHz.
You can change that of course, as in what the minimum and maximum values are with a program called SetCPU, but the phone must be rooted.
Hope this helps
Ok. i have refraind from asking questions for quite some time. I have lurked, and read and read and read. i learned how to flash roms and kernels and most otherthings i want to do without bothering anyone with noob questions...up until now.
I flashed the suckerpuch #50 kernel in attempts to try out 1.4ghz, but unless im completely missing something my phone dosnt ever seem to go above 1 ghz on this kernel. im not positive this is the case, but heres what leads me to beleive it:
cpu usage widget on my screen never shows above 1ghz, while a different 1.2ghz OC i tired shows it peaking up to 1.2 right after boot, and if i exit quadrant it shows 1.2 for a sec before dropping back down, same with any 3d game, when i quickly close it and look at the widget, it will show running at 1.2. Yet suckerpuch never shows above 1.0 UNLESS i run CPUsetting and set it to "performace" which it then appears to be running at 1.4 AT ALL TIMES, and the phone isnt stable so thats a no go.
am i missing some key piece of information here? did i flash it wrong? is there some other type of modification i need to do to get it to actually run at 1.4?
ive read through the suckerpunch #50 opening posts multiple times and i believe it tells me i need to modify some file or other, possibly, but im not understanding.
any info/help would be much appreciated!
P.S. this forum, the devs, and all the things supplied to make my phone awesome are absolutley great.
I believe SuckerPunch is set to 1Ghz as default unless you change the setting with Voltage Control (or SetCPU). Mind you that 1.4Ghz is not run well on a lot of devices and may cause freezing. And I'm glad some people take up reading before asking questions
p.p.s- im aware not to use set CPU.
honestly i cant see the point of it with any kernel. dosnt seem to do anything.

yeah im using voltage control- minus 125 on all and the phone seems to work well.
i just find it weird that the kernel peaks at 1ghz, where as another peaks at 1.2ghz (both without use of setCPU, and WITH use of Voltage control)
when i was using setCPU and putting it on performance, i could see it was running at 1.4, pretty much at ALL TIMES. MOST things ont he phone worked well, ultra fast. the problems i noticed is that neocore would freeze (which i understand to be a sign of instability) and speedtest would either give me REALY slow speeds, or force close every time. were as set on conservative it would work perfectly and neocore wouldnt freeze.

I guarantee you you cannot run -125 at 1.4GHz, unless you have some kind of wonder-phone.
In Voltage Control, you're set to 1.4GHz, correct?
If you are, have you made sure to enable the 1.4GHz state in Voltage Control via the bottom menu as well? If you don't, even though you're set at 1.4GHz it will not run at that.

my bad, im running -125 on i think its the gb 1.2ghx kernel. thats working fine.
im going to reflash #50 and try what you said.....though im pretty sure i already had it set. i know i was setting the mv from 100 up to 1400
ok i flahsed back to #50, and went into voltage control. it DID cap my freq at 1000, i changed it and set 100 through 1400 to -75mv.
i ran stress test for about 30 seconds and exited, and my CPU widget shows 99% usegage at 1ghz
hmm
i flashed back to gb reorient 1.2ghz and during boot up as soon as the CPU widget loaded it shows 1.2ghz. ran stress test again and exited in the middle of it, widget showed 99% usage at 1.2ghz.
i realyl dont know what im missing here, but it does seem as thought the suckerpunch #50 is not running above 1ghz for me.
comparing all forms of benchmark type tests between the two kernels, everything EXPCEPT necore is scoreing better on the 1.2 kernel. neocore onthe 1.3 kernel is giving me 55.4 fps, whereas on the 1.4 kernel its giving me 65 and some change fps. i know benchmark scores arent that meaningfull in some cases, and on the #50 thread it even states that some may be lower on that kernel.......but i swear ive done something wrong because i dont see how it can be running at 1.4

Like I said in my previous post, are you actually enabling the frequencies or just selecting 1.4GHz as the max in Voltage Control?
You have to enable 1.4GHz in the "states" menu of Voltage Control for it to work, as well as set 1.4GHz as the max in Voltage Control. SuckerPunch does not overclock by default because a lot of phones do not play nicely with 1.4GHz.

ha. this had me confused......there was no "states" menu. that got me pokeing around and then i realized i didnt have the newest version of voltage control(had 2.0 instead of 3.0). i do NOW. and i see the option to select the states. so, i selected 7 states up to 1400. and selected the max frequency of 1400. set a voltage for all, and applied.
still the same result. lol. its not running over 1ghz according to cpu stats. it SAYS it frequency range is from 100 to 1400. but it aint going over 1000.
*sigh* there has to be something else im missing
For suckerpunch's new builds, it's set to startup at 1ghz. After like 15mins. you can run some tests and it should be at max clock.
YESSSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ITS WORKING! and dayum i see and improvement in stats! benchmarks look fantasitc, neocore isnt freezeing, phone isnt freezing on lockscreen.....will have to run stress test for a while to see for sure but it appears stable!
1400 -50
1300 -50
1200 -75
1120 -75
1000-75
800- 100
600-100
400-100
i really cant figure out the right way to do that, but it seems to be working so far
for one, i needed the newest version of voltage control.....for two, im thinking that i was supposed to wipe the davik cache before install, because it did a different song and dance when i did that. for three.....for whatever reson the 1000hz version didnt seem to want to work for me....and finally....waiting for a while after the phone booted up i did see the CPU start to jump up to 1.4.
thanks guys!
Hi there,
I'd like to overclock my IncS to 1,3 Ghz...
But I don't know the right settings.
Can you please tell me the right setting for best performance (e.g. oc to 1,3ghz) and best battery life?
thanks
does anybody know?
Set max to your desired, min to the lowest it will go and scaling to smartass.
I'm OCd to over 1.4 and no issues... UCd to 192 with smartassv2 governor
Sent from my Incredible S using XDA App
the best performance I have experienced in my INC is when I put oc / uv beater to the following:
wake gov: ondemand
wake mins: 245000
wake max: 1228800
Sleep gov: Conservative
my sleep: 245000
Sleep max: 691200
when I take a test in antutu nenchmark for I the following result.
score: 2729
If I clocked lower or higher, the result is lower
Overclocking depends entirely on your chip.
You should use whatever governor suits your needs.
I personally use ondemandx which speeds up on demand (as the name implies), conservative tries to keep the frequency as low as possible, interactive uses max frequency if min isn't enough, smartass is an improvement of interactive that keeps performance high while improving battery life (meaning there's little reason to use interactive).
You can find it in more detail here.
So basically, smartass if you want performance, conservative if you want battery life, ondemand if you want something in between. In reality though, I don't think you'll see much difference between them and I've seen no difference in idle power draws, so if you don't use your phone all that much, they won't be that different.
Once you've picked a governor, you should set min speed to 122000 (no reason to use any higher) and max to whatever you want. Your phone will probably crash or suffer from bad performance if you go over 1.5 GHz, but it varies a lot. Might happen even earlier.
Once you've found your desired performance level, you should start tweaking your voltages. You can do that under the UV profile. In there, you can adjust voltages at different speeds and the phone will automatically use them at whatever speed it's at. You should undervolt to increase battery life, so start by reducing all by 25 or 50 and then temp apply. Use it like that for a couple of hours and if it doesn't freeze, you're probably stable. You can either stop here or spend many hours tweaking it further, but that'll take many hours to get right.
This is my setting

In my opinion, and I'm sure many others', Virtuous daemon is the best by far.
It comes standard in a lot of roms, and using the OC/UV beater
http://forum.xda-developers.com/showthread.php?t=1207546
it would have the best performance. I've set mine similar to yours and with this method, you can set the phone to underclock when battery reaches a low level
Setcpu determines that 1704mhz can be achieved, would it be safe running the GNote at that constantly does anyone know?
Hmm...
I would say, this is depending on more than only the frequency,
if you set the voltages for 1704mhz on e.g. 1650mV u'll get a very hot phone and a hot accu... this will not be good for ur phone, if you're doing this constantly.
But if u find a good compromise between voltage and frequncy, u can do this constantly.
Also you could make profiles in SetCPU so that for example if you're gaming it will set voltage and frequency to 1704mhz and if your screen is off, it setz frequency to 800mhz.
So you have to decide if u'll want to take the risk...
I hope i could help u and sorry for my bad english,
Schnizel.
Aside from benchmarks theres no real benefit from running at 1.7ghz. Most of the time thebphone stays at 200 to 1200mhz
safe?
thought overclocking is always a risk. think nobody here will tell go do it its safe is there ?
and why would you overclock a 1,4ghz dual core in a mobile ?
Thanks, i've seen in a different thread that the voltage would need to be lowered so overheating isnt too bad.
SetCPU gives information on what frequencies are used by percentage and mine is either minimum or max so it suggested its topping out while doing stuff....
1.7ghz is too much for a constant setting.
I had my phone at 1.7 and while watching Netflix on 3G, it would get TOO HOT. and i mean TOO HOT.
I have this tabled for a long time, but as i rarely used it i didn't bother with it much. From day one back in 2014 the tablet was sluggish and laggy, today is just unbearable even for browsing. So i have decided to take a look of what can i do.
I have installed the latest (10.26.2019) LineageOS-14.1-Deathly with gapps nano.
I have installed CPU Throttling Test from the play store and start testing to see what's going on. I saw that the CPU Throttle instantly (like in 10-15 sec max) from 1900mhz to 600mhz, and this is where the sluggishness comes from, the CPU is constantly throttled no matter that you are just looking at a simple web page.
I started playing with the Deathly Adiutor and under-voltage the cpu, set the max to 1400mhz and this is where it is stable as it is. At 1400mhz constant 100% CPU stress the CPU temps are around 90c (at 95 the cpu starts throttling). Anything above 1400mhz even with under voltages CPU results in throttling within 1-2 min, but even like that at 1400mhz and GPU set to be always used and at minimum of 480mhz (with setting in dev options to always use gpu for 2d composition) the performance was really much much better then the stock settings.
I have continued to play with it and noticed that if i apply pressure with my fingers on the back panel just below the camera where is the most hottest, the temps are dropping 10-15C, so i have opened it and i saw the issue.
The issue is that the metal shield radiators does not make a good contact with the thermal pad on the back panel, and thus can't dissipate the heat well. This may variety from user to user as some back panels will make better or worse contact, but its far from ideal.
Its good that i have some spare thermal pads around and i have applied them, and the result is perfect, drop in 12-17Cfrom stock setup under continues stress.
As a final result i have managed to bump the CPU from 1400mhz to 1600mhz with 1087mV voltage and at max 84C (down from around 90 at 1400mhz) at constant 100% CPU stress. The performance gains are around 100 to 150% (At around 42-47k GIPS up from 20-25k GIPS stock in CPU Throttling test). Additionally i have to say, its extremely easy to open the back cover panel.
Furthermore, i made an video to see how it runs and the settings i use.

I'm attaching before and after the mod photos.
Quick followup, i have run 3D Mark benchmark and PCmark, see the screenshots below. Managed to achieve the world fastest Tab S, enjoy

Its not the minimum CPU frequency that gives you the performance boost, its the maximum frequency limit at 1600mhz down from 1900mhz, as i explained, to gain the performance, you need to avoid CPU from overheating and throttle down itself to the ground. That's why the max frequency with the thermal pads and improved thermals is 300mhz below the stock 1900mhz, and without the pads my max stable frequency were 1400mhz (500mhz below stock).
The minimum frequency will only smooth out initial animations and things like that, but don't have much of an impact on the overall performance. With that said, increasing the minimum frequency ofc will eat more battery and you don't need it, you can safely set it to 650mhz (as low as it allows) and depending on your kernel governor policy should have the same or better battery life. As i said, the main gainer is preventing the CPU from overheating at 1900mhz and throttle down to 650mhz where it sits most of the time with stock settings.
In fact if you limit your max frequency to 1400 or 1600mhz depending on your stable thermal results, and set minimum to 650mhz, you will see the performance gain AND significantly increased battery life due to that CPU does not go to 1900mhz and does not eat that much power and voltage. You really need to fine tune it depending on your needs, but at stock CPU throttling down to 650mhz and staying there is an manufacturer (Samsung) failure, and if i were discovered this when i bought it, i would wanted refund, as they advertise 1900mhz CPU which almost never works at that frequency.
I tested this method on other tablets and phones, and while it happens on other devices to throttle down after 5-7 mins (not after 15 sec), i have never seen to throttle more then down to 80% of the advertised frequency, but the Tab S goes almost immediately down to 35% where it stays and cripple the device. Its really really bad engineering from Samsung.
Going to try this.
Thanks
A lot better .
What thickness of thermal pad should I buy? Probably will buy from Amazon unless I need to make a trip to Microcenter. Thanks for this suggestion @nauvho

Well as you can see on the picture, the CPU bed already has one black pad by Samsung by default which is around 0.2/0.3mm i think, but it does not make contact, so i put on the CPU radiator 1mm pad and on the other radiators i put 0.5mm to equalize in case my pad is too thick. Your guide should be how easy is to close the back-plate, if you need too much force you may need thinner. So i guess you can take 0.3, 0.5 and 1mm pads.
effing A
Wow
Applied the same settings that you show in the video and WOW! It's like a new tablet. I didn't even put thermal pads.

just rooted t800 with MM + trw + SU.
added some thermal pads like in the pics.
installed Deathly Adiutor ....which said that doesn't like the kernel..and doesn't let to change the cpu max speed, and the voltage page doesn't even exist
installed Kernel Adiutor from playstore with which I can lower the freq, and for 1600 it works 1-2min at 27-28000GIPS then starts to throttle

Why are you using MM? Also, did you noticed that center pad is thicker and side ones are tinnier? what are your CPU temps? Also probably due to MM, but I'm getting around 42gpis (average) at 1.6, but you should really check your pads placement, thickness and temps, put the CPU under load note the temps before throttling down.

I'm using MM since I don't know if it worth to upgrade; does this LineageOS work well...all features (cam, scanner, soud etc) works with it?
used 1mm pad over the cpu... 0.5 otherwise (china made); also removed the small factory pad and placed another pad patch there; the back cover heats well and I assume that the heat doesn't have where to go.
since it's not throttling at 1600MHZ (almost 100%, take a look at the pic)...from where to get more than 28GIPS?

I don't think removing the stock black pad were a good idea, I did not removed mine, my pad is next to it. Also CPU throttle app is not reliable to monitor cpu temp (at least for me) , you should do it by starting the throttle test and then switch to deathly auditor and monitor the temp and clock there or other app like CPUz or Aida. Look at the video how I monitored the temp. The CPU will start throttle at 93-95c so your temp of 81 cannot be accurate if it throttle. Didn't you said that you throttle at 1.6 in your previous post?
Regarding the performance I think it might be eigher app difference between mm and 7.1 or due to MM itself. And yes everything is working perfectly for me with lineage, camera, fingerprint, everything is fine and it is mile better then MM imo.
installed 7.1
pcmark 4330 with your mods.
so the thermal pads doesn't matter on MM.
from my testings on 7.1 the boost in pcmark comes form setting max freq 1600 + undervoltage (3000->3500), and another boost...by setting the lower freq to 1600 (3500->4300)

Nice.
About the pads, they matter only if the CPU temp under load drops when you apply pressure with fingers on the back cover as i explained in my first post, but idk if this apply to all tablets or just mine. The boost comes from not throttling the CPU down and being stable at maximum possible frequency. The CPU can go up to 1900mhz and beyond (2.1 by spec), but the cooling is not enough for that frequencies.
I think that adding an 0.5-1mm copper heat pipe thru radiators or copper heat pads similar to flagship phones might push it to 1.9, will order some someday and try it.
now it will be interesting ?% it's the termal mod in this boost, which means, performing the test in PCMARK only with steps 1+2:
1. LineageOS-14.1-Deathly
2. Deathly Adiutor (which requires step 1) + CPU max freq 1600 + undervoltage at that freq + CPU min freq 1600
3. Thermal pads added inside the box.
Since I started with thermal pads...I can say that in MM it doesn't matter.
-after upgrade to 7.1 as I said..PC...MArk around 3000 (thermal pads mounted)
-after setting max freq 1600 + undervoltage I got a boost in PCMark to 3600
-in addition, with min freq 1600...got another boost..to 4300; in this turbo state..the battery drains quickly, but the interface it's fast like the wind.
PCMark doesn't use CPU at 100%, it counts also how fast cand do certain short tasks...and this matters because if CPU it's in it's low power states..it loose time to rise its freq and do the calc at full power.

Thermal mode does matter alot, CPU thermals is everything, the lower temps are, the higher frequency you can push the CPU, more frequency = more performance. As i said, without the thermal pads i could not get 1.6ghz to be stable, only 1.4 were stable-ish.
In stock rom, CPU governor and states are set according to the temps with the stock cooling. But if you don't change settings it wont change much. However Samsung engineers did a terrible job with those default settings, so as i explained in my first post only doing the software changes had dramatic impact on the performance because you get the CPU stable even at 1.4, but the thermal mod push it further to 1.6
The true performance benchmark is the 3DMARK (my screenshots 3 and 4 for score "ice storm unlimited" test and "Sling Shot" test) this will push your CPU and GPU to the max, PCMark is more about daily use performance and also can be used to measure battery performance between different settings.
Yes leaving CPU with minimum of 1.6 will drain battery more quickly naturally, is using more power, i leave mine at 1.2 as minimum, but minimum speed should not matter much in benchmarks if you are using the same as mine CPU governor. CPU governor basically tells the CPU how to behave, like how quickly to rise the frequency, for how long and etc.
