what exactly does over clocking do, I think I have the general idea of what it does...... and what do you over clock 2?
overclocking changes the frequency at which your phone's processor works, thereby making it faster. You use batterystatus to overclock. Most of us overclock to 243 or 273,i believe
Your upper limit depends on your particular device. Some can only overclock a few mhz past the stock 201mhz. Some can overclock to 299+.
But it basically allows your device to perform faster at the cost of battery, heat and technically longevity.
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

Which would be the best O/C program out there ?! I have SetCPU, Daemon but I'm sure there is better in the market...... just need to know the name so I can get it Thanks!
I'm currently 230MIN/1150MAX

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.
READ EVERYTHING BEFORE ATTEMPTING ALSO DO SO AT YOUR OWN RISK.
Required. you must have an oc and voltage support kernel. jfbs stock roms have both oc and voltage. cars1189 stock rom does not but he provides link to kernels that do. Dont use exuv or uv kernels while doing this. well you can but if your new to this it is recommended to use regular oc kernel without uv/exuv. Also ram size does not matter.
What else do you need:
an app that allows you to change clock speed and voltages. if you dont already have one get performance control here (i use this thanks to jfbs for finding it).
*NOTE* never ever leave phone unintended when doing this until you find your chips sweet spot. YOU HAVE BEEN WARNED. otherwise if you listen and follow my advice you wont cause any major harm to your phone or any harm to your phone. Also do NOT have the settings apply at boot until you find all your settings. keep a pen or pencil and paper ready so you can remember workings settings.
1. remove case (if you have one on your phone) and battery cover. (this is just a safety precaution should your power button not work to pull that battery.
2. open up your overclocking app. (in my case performance control). set min and max frequency/speed to 245mhz
3. go to voltage settings and change the current voltage for 245760khz (really 245mhz) which is stock 900mV to 875mV (decrease by 0.25). close app out swipe around home screen and apps draw. open and close contacts list and see if phone freezes. we are not worried about phone running slow at this point until you reach 1ghz+ point of this. IF phone freezes/locks up hold power button to reboot phone or just pull battery and put it back in (personally i just use power button). if phone doesnt not freeze lower voltage again by 0.025 which should be 850mV. continue this process until phone DOES freeze so make sure you you wrote down last working voltage and as soon as phone freezes reboot or pull battery.
4. Once you found the lowest working voltage for 245mhz up the min and max frequency (speed) to 368mhz (368640khz)
5. Do the same thing as step 3 which is decrease the voltage by 0.025mV for the frequency for 365mhz. and repeat for each frequency up to 1ghz. Once you get to doing 1ghz voltage and above. The testing phone phase will be different but still flow the decrease by 0.025mV. for testing use any 3d game not candy crush type. and let it run for at least 10mins actually playing with phone plugged into charger. when you reach the spot where the phone freezes unplug both charger and force reboot/pull battery.
6. Once you find all of your working voltages for each frequency then you can set min back to 245mhz and your max to which ever you was able to hit. then set all of your volt settings in and save it for set on boot.
Note. 1.2ghz-1.4ghz seems to be a very good and safe battery to performance ratio. even more so if you followed my directions properly.
EDIT:
My settings for comparison.

i just got this phone only a year ago... also the guide should work for any phone that has oc and voltage control support. but thanks
my new phone, motorola droid, is not as developer friendly as the samsung. i should have done more research before getting it. motorola and verizon have it pretty locked down, no flashing and awesomeness. getting root privileges was a 15 step process.....oh for the days of flashing with the exhibit...i still have a red case and a green flowery case if anyone wants them.

any electronic can be overclocked and under/over volt. Over voltage is fine if electronic requires a outlet to run e.g pc. game consoles. while undervolt is best for battery operated devices as you would want to have long operation time between charging xD.
Updated OP with my personal settings for this phone.
Thanks for the guide, Will be giving this a try this weekend... Well this and possibly flashing that new Mahdi Rom for the exhibit
Thanks!

all of jfbs roms are overclockable by defualt so just download performance app and follow instructions. be save and watch temps if your overclocking keep it below 35c is possible or if battery gets really warm.

Thanks for this response one more question what are the benefits of overlocking my phonr aside from more batery lifee??? ... i wana give this a try so i can keep using my exhibit
Thanks!
This will be helpful when undervolting my parents' phones.
undervolting will give you the better battery life while keeping the same performance
overvolting will drain the battery faster
underclocking will drop performance and save more battery life then just undervolting
overclocking will give you better performance
When it comes to any mobile device it is recommended to undervolt and overclock as you want as much battery life as you can while getting a performance boost or just to undervolt to save battery only.
Desktops are made to handle heat and voltage a lot better thus most ppl will overvolt and overclock to get the fast possible performance as you are always connected to a main power source.
@TripFX, thank you for the comprehensive OC & UV guide. I've been tinkering with the voltage settings for about a week via Performance Control and I think I've found a good spot for both my Exhibit devices.
Here are my settings (using cars1189 Christopher K^Kernel uv vhm 9-9-2014 build)...
EDIT: Updated voltage & CPU settings.
CPU Frequency:
Max. 1401 Mhz
Min. 368 Mhz
Voltage Settings:
122880KHZ - 750 mV
245760KHZ - 750 mV
368640KHZ - 800 mV
768000KHZ - 925 mV
806400KHZ - 950 mV
902400KHZ - 975 mV
1024000KHZ - 1000 mV
1113600KHZ - 1025 mV
1209600KHZ - 1050 mV
1305600KHZ - 1075 mV
1401600KHZ - 1125 mV
Btw, 750 mv is the lowest 122880KHZ, 245769KHZ, and 368640KHZ can be set to using the kernel mentioned above. If anyone wants to go lower, you'll need to try a different kernel or one of jfbs ROMs. cars1189's uv kernels seems to do okay (every device is different though, so be careful) but I would strongly advise against using exuv (both my devices couldn't handle exuv).
Also, device temp. has decreased by a couple degrees overall, couldn't be happier!

I almost copied your exact settings for my T679 and it's running nice (I've set min/max to 245 MHz/1209 MHz)
However I was curious as to what you've set for Governor and IO Scheduler; I've just left it on default: ondemand and row. Any other special settings or tweaks?
I ask because temp has definitely lowered, but battery life *I think* seems to drain a bit faster (though I do have a bunch of communication apps that probably sync throughout the day).

as far as more tweaks to boost performance. if all the apps you use is art compatible then i'd suggest switching to art. massive cpu difference between davlik and art. least from my own experience. as far as battery drain i would recommend using an app such as greenify. for gov's and sched. mine i left ondemand but sched put it on sio. however i recommend reading over this as it will help you get a much better idea of what would work best for you. everyone uses the their phone differently so it should technically vary from person to person.
Just a heads up to anyone undervolting. Be careful undervolting below 750mv. I noticed on my phone that the battery started overheating at 725mv and below. 750 and above was fine.
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.
