Overclocking pros and cons??? - HTC Incredible S

I want to know wat r d pros and cons of overclocking..
As far as i know pros are better performance..
Con: reduced battery life..
Plzz add ur suggestions in d list..
And does overclocking processor reduce d lifespan of device?

Overclocking will reduce the lifetime of the CPU, but honestly I don't think that you'll really notice it.
If you lower the voltage you'll also get the same or even better battery time even though you overclock it.
If you overclock too much your phone will most likely start to freeze or just shut down.
Can't really think of any major things that might happen.
And pros; games will run more smoothly, you can have more applications running in the background without lag because of the CPU. If you're running out of RAM an overclocked CPU won't help you.
That's all I can think of right now, and hopefully I haven't mixed up anything

Maybe you should read that
*hopes that it doesn't say the exact opposit of what I just wrote here*

If you're undervolting, the processor shouldn't overheat therefore less battery loss and less chance of any damage.
You can overclock our phone processor ~300mhz without seeing any overheating or bad battery drain. I just wouldn't recommend over that for very long periods.

But, there might actually be some phones that will start freezing just by overclocking 300MHz too
Forgot to mention, in my previous post, that how far you can go with overclocking is really device specific, it can differ a lot from two different Incredible S. I remember from the community for my old phone that some people couldn't even overclock 100MHz. CPU's for phones aren't really made to be overclocked, so do it with caution.
And to find out how much you can overclock your CPU, in your phone, just take it easy and go like 50MHz/time and perform some sort of a stresstest of the CPU, when it start to freeze and/or turn off you've gone beyond the limit of what your CPU can take. And don't set the frequency to as close to the limit you can, set it like _MAX_ 50MHz from the limit, I'd go for at least 100MHz below the limit.
Hopefully someone appreciates this post, and if anyone want to point out something I've gotten wrong... please do.

I'm going by this chips specific tolerance, fyi I'm an electronics engineer.
I strongly doubt anyone's phone would not be able to overclock at all.
You just have to watch the heat really. Overall, 200 to 300MHz is very safe.
This generation snapdragon has high tolerances.
I have gotten mine up to 2ghz.
Freezing generally won't occur until after about 1.6ghz, or if the undervolting is too severe.

Any chip can overclock, it is certain undervolt levels that cause most to freeze.

How about hot countries like Egypt ??? And pocket kept phones.
Would that fry the cpu ??? If overclocked I mean

There is thermal overload protection built, the phone resets when the CPU reaches the temperature threshold. So a moderate overclock should create no problems. If the phone is rebooting though you should think about scaling back.

Sorry for bumbing old thread
Biggest issue I've came across with overclocking are the voltages. Took me half a year to adjust CPU voltages even till this point where I can overclock 100mhz. Since not all devs share their acpu table, its impossible to know how severe the undervolting is in particular ROM.
Every CPU is different, and mine needed 100mV(?) higher voltages than the ARHD native voltages to even stay at 1152mhz without insta freeze :/

CPU overclocking does have pros and cons, and I think the cons tends to outweight the pro's but it all depends on the type of user each person is. The only pros means you save a few seconds doing something, or get a better benchmark score - for what reason? I will explain below.
Overclocking can give you that 0-40% more boost. This can show from our stock IncS @ 1.0GHz = 3000 antutu score, overclocked becomes 3600 or 4000. That is a benchmark score, it's just numbers and don't mean real world performance.
How about when you are gaming? This doesn't translate immediately that you will get like 50+% more speed, it's more like in a shooter game your FPS jumps from from 18FPS > ~22 FPS, with a 30% overclock. it's just a measly 3-5 FPS. Often times, this also comes with instability causing freezes, reboots, or a hot phone, and extreme battery drain.
Whether you can tell the difference or need that extra power is up to you and each person, but personally I find that it's a gamble to take that has little gains other than telling others "hey I got this benchmark score"! Good for them.
Now, underclocking is a different story. While in theory it shouldn't cause any problems to the CPU, the purpose is 99% of the time to prolong the battery. This is what voltage controls in kernels are all about.

The GPL requires whatever kernel that is distributed becomes open source. If you find a developer that doesn't share with you the kernel source they are using, you can complain about it. They are violating the policy that makes android/linux, the OS it is. Most developers tend to take someone else's kernel and bundle it in their rom, but the original creators of the kernel should usually have a source up.

Meaning: DEVs usually just share a link to github. It's pretty frustrating for "newb" user to even find the kernel source code from there. Seen one ROM where MDJ actually posted the acpu table and it was easy to see the voltages and adjust them to be alike with another ROM/(Kernel) that had trouble with O/C.
As for the Overcloking generally, I only find I usefull if kernel supports governor like smoothass, which really boosts the smoothness and I can truly see the difference.

well, just ask them where it is then. I'm sure most would tell you to look at that acpuclock source unless they were just not cool with you for some reason.

Thank you so so so much ! Yes I know that apps like incredicontrol can show it, but don't want to flash all the possible ROMs and their versions just to find out that when it could be available this easy. Also I can compare values more easily this way, rather than from the screen of my INC S.
But still thanks again! Oh and yea draftted slighlty from OP's question, hope he doesn't mind

Very cool i liked omg

Overclocking a phone's CPU is really an hit or miss. In Benchmarks you'll most likely won't see any improvement. On the other hand, GPU overclock seems to be much MUCH more worth It. It brings real benchmarks and gaming improvements.

i'm an experienced overclocker and i'd say that the cpu won't reduce life if the temperature and voltage aren't too high: less than 60°c under 1.6 volts for silicon (combined of both) and CPU is not afraid of continuous work in spite of high frequency (10GHz, 100GHz), as said it only shortens its life when the temperature and voltage are too high. silicon can withstand up to more than 2 volts but 1.6 on average. and unstable cpu overclock the main cause must be the temperature and the components around it like Ram, Motherboard, not the CPU itself. example an intel e6500 cpu has a base clock of 2.93 GHz is overclocked to over 9GHz with excellent temperatures and voltages and fully stable.

Kernel Help, UV and Improve I/O performance

Ok, I'm working on building my own kernel. Now I got how to do the overclock and such, thats easy. What I want to know is what is going on with what Barak/Eugene does and what Team Whiskey does to the kernel to improve the I/O. Also wanting to know what JAC/Team Whiskey set their voltages to?

Good luck I have been trying to get voltage out of simbionix all night. For some reason, its like their kryptonite, no one wants to talk about it.

Thanks! uh, I just wanted the voltage table for the Project Core because I want to see how much Team Whisky overvolted the CPU at 1.2 Ghz.
I looked at a captivate post and it stated that stock voltage for 1.0 Ghz is 1.275 v (?) so, Core has a good .075 voltage increase at the highest clock.
P.S. I can't figure out what the 3rd number column of that table indicates, if you know please enlighten me.

Some how I'm thinking {1200000, 1350, 1100, 0} 1350! This is a abit of overcooking for me.
This is getting just a little to quick to compile " a new and improved kernel ". No ill meant but just thinking out loud..

It's cool. But can you introduce it's feature and difference with the MDJ's kernel?

well the main difference is the CPU VDD table. I have more steps on the lower end. MDJ also has support for TMobile usa wifi calling. MDJ is a great kernel and I have nothing bad i can say about it. I just made a kernel the way I like it. If you are happy with MDJ kernel I would stay with it.

Awesome work brother !! waiting for a rcmix 3d rom now i guess

That's a high overclock limit! Quite tempted to try it, is the IS stable at 1.9GHz?

well I have it set to stop at 1.6 right now. Ill release an OC+ version soon. Each Phone is different so If you decide to OC to 1.9 do it in small steps. I keep mine at 230 / 1.3 smartass.

Can you tell me the default sleep-max-freq and min-freq?
As my previous kernel is MDJ's v2, these two values are 245760 and 368640. I guess I need to change them to appropriate values on your table.
Besides, I see the sleep governor is called conservative. Is it built in your kernel?
Thanks.

mine are 230 and 384400, You can go as low as 122 for the min.

Actually, I think RCmix Kernel is a more stable and it gives far less heat than MDJ's.
Good Work!

Nice, very nice

This is a nice place to look out for Ur great work, it came to my favorites.
By the way, still working perfect for my needs, thanks again!

I guess one of the main differences you haven't mentioned is the improved wi-fi range? I haven't tried this out yet, but people not monitoring the ARHD thread will want to know about this feature!
Is underclocking below 245Mhz likely to give significant battery life increase? Is there any reason you don't go below 245 as your minimum?
Thanks.

Call Recorder
Just installed the latest kernel.
I've tested the call recorder and it seems to work well.
However, I imagine this will be a drain on battery?
Could we have an easy option to disable this permanently, rather than having to go into services and manually kill the process? Maybe something like 'Set on Boot' or the option to not start the service at all.
Thanks.

Glad it worked. I followed avs333 on where to place the edited files and had a look at mdjs kernel to make sure. I'm glad it's working. It won't record unless you turn the apk on.

[DEV][WIP][KERNEL-PATCH][MSM7x30/8x55 GPU OVERCLOCKING][2d-core done][3d-core][v0.7]

Finally after someone pm'd me I looked back into GPU Overclocking.
New thread created issues with old thread OP permissions (people seem to be asking the same questions over and over again all information will be kept in OP & DO READ THE THREAD, repetitive questions will now be ignored)
Benefits:
Smoother UI
Handle 2d & 3d core GPU intensive applications & games
Currently only 2D core has been overclocked working on 3D core OC
2D-core original value - 192mhz OC to 245mhz DONE achieved 25% performance boost grp_2d_clk outputs 245760000hz
3D-core original value - 245mhz OC to 300+mhz WIP hoping to achieve 40-50% performance boost
2D-core OC only Download: Coming soon...
Download Links for other devices coming soon...
Works for all HTC Sense/Cm9/Cm10 kernels (Just ask a kernel developer for your device to implement the source code)
Note: Don't have internet on PC so providing 3 main files that need replaced for 2D-core OC to work
Download link to source code: http://d-h.st/wbH
3D-CORE OC TESTS Download: Coming soon...
Do check under sys/kernel/debug/htc_clock/clks/ look for file with all clocks & look for GRP_clks (Graphics clock)

OK so basically today I've been thinking and I've come to the conclusion that I will release the 2D-core OC patch As Soon As Possible, 3D-core Core OC is NOT Impossible but for now I'll give it a break, I will attempt 3D-core OC If/When I can get a hold of a msm7x30/msm8x55 device, as it will make it much easier for both me & users.
So for now you can enjoy the 50mhz increase/bump up, perf boost 25% in 2D-core (will increase performance in both 2D/3D intensive appications as 2D-core is used for 3D AFAIK and increase User Interface performance (Note: This will not take a hit on battery life)), I will also release a couple of fixes on patchas kernel that shouldnt be there/set etc.
(Theres a device available in my area for roughly £90, if anyone wants to contribute towards getting that device or can donate a device , more than welcome and shoot me a PM so I can list you here.)
(This isnt a promise of 3D-Overclock if you donate, if you donate please do so expecting nothing I will only attempt 3D-overclock)
Working device list - all kernel 3.0+ msm7x30/msm8x55 soc devices.

Benchmark are not really something that should be taken too seriously but yes antutu reported in 20-25% increase in performance not always accurate but 2d core clk results in 245mhz, user from desire hd reported going from in range of 2x fps to 4x fps and that is without the 3d-core overclock (2d-core is used in 3d graphics afaik)

I was in IRC before you came on, talked to synergy, I've changed the OC code, removed mistake and set GPU OC a different way, guess what? tested on my sisters phone again and benchmark was improved, not majorly but on 2 of the draw tests, consistant results of improvement by 5-8fps and rest were by 1-2fps, but like I said lets see where 3d-gpu OC takes me, as that will definitely show if OC is working
What you guys got and what I got was different in benchmarks, which is weird, I got imrovements, you got the opposite. So can't call it an empty OC lol

your improvements here : 0xbench is very small, and should be higher if it is oc'ed , but yes its a plausble

Okay after looking @ GPU Overclock for 2 weeks, This is the news on GPU OC for MSM8x55/MSM7x30 socs.
My findings...
2D-core OC from 192mhz to 245mhz successful.
3D-core OC will not happen without me obtaining the datasheet (which is proprietary)
The clocks are protected, via Ownership/Permissions, and maybe an RCU/MPU
No Overclocking the CPU does NOT Overclock the GPU, thats the worst thing I've heard in my life lol.
The lowest the GPU can hit is 192mhz or lpxo freq
Bus is not overclockable, it always is 192mhz
EBI_2D_clk will and has always been 0mhz
Modifying kgsl platform data and/or the graphics table with random values or even calculated values from correct pll freqs will NOT OC the gpu
it's ashame the GPU clocks are protected.
IF anyone is looking to continuing this project and is on the right track you're more than welcome to get in contact with me, especially if you have the msm7x30 datasheet.
The QSD8x50 soc is more open than this soc, so I'm doing a few tests on the HD2
Also it is overclocked, wasted my time testing, measured the gpu frequency and output to dmesg tells me it is correct, if it wasnt setting then the dmesg would ouput it failing to set the gpu frequency. just like it does for 3d-core oc

it was said before and ill say it again, the gpu clock is relative to the cpu clock, you cant overclock the gpu, their all part of the soc "system on chip", you can increase the bus bandwidth etc, which is already present in my kernel, but performance increase? not any atall

Nexus 5 Voltage How Low Can You Go.

When I start my day with my phone my ultimate goal is to get the most out of my battery. I have a Nexus 5 which is great phone but one downside is that the battery which is 2300mah can barely get you through the day. One way to help this issue is to under volt your CPU, the nexus 5 has a snapdragon 800 CPU clocked at 2.26GHz which is power CPU but at times it can run a bit hot and use more juice than it needs. By Under Volting your CPU your device will run much cooler without losing performance. (Warning if you go too low with the voltages your device will freeze and randomly reboot. ). The voltages than the nexus 5 ships with are a bit high I've been able to under volt up to -75mah without losing any performance however your experience may be different. To under-volt your device you need to have a rooted phone with a custom kernel installed. Franco, ElementalX, and Codeblue are few a few of the many kernels you can use with the nexus 5. I've been using ElementalX as my kernel for a while now, although Franco is also a good one. I use the ElementalX kernel app to manage my voltages, its a paid app but its definitely worth it. you could also use the Kernel tweaker app to manager voltages as well. I've set the governer to elementalx and i set the max cpu freq to 1574MHz, and the max screen off frequency is set to 729MHz. Don't go to extremes take small steps. Please let us know your results here.
This is what i have so far.
300MHz = 650mV
422MHz = 650mV
652MHz = 700mV
729MHz = 720mV
883MHz = 740mV
960MHz = 750mV
1036MHz = 760mV
1190MHz = 780mV
1267MHz = 790mV
1497MHz = 830mV
1574MHz = 845mV
1728MHz = 875mV
1958MHz = 945mV
2265MHz = 1000mV
Edit:
my pvs is 2
300MHz = 650mV
422MHz = 650mV
652MHz = 700mV
729MHz = 710mV
883MHz = 730mV
960MHz = 740mV
1036MHz = 750mV
1190MHz = 770mV
1267MHz = 780mV
1497MHz = 835mV
1574MHz = 840mV
1728MHz = 875mV
1958MHz = 965mV

You should be able to go as low as 650mV for both 300MHz and 422MHz., without experience unstable behavior.

Just remember in a couple weeks if you notice stability issues or your phone rebooting, it's probably because of these changes.
Personally I value 100% stability, and I'm already able to achieve the same battery lifeout of default clocks and voltages as well as stock ROM and kernel. Such as these 5-6 hour SoT examples using 40% Adaptive Brightness.

Also I think you'll find lowering the voltages by 5-10% doesn't make a noticeable difference in battery usage, thought it should run cooler and throttle less.

Going to give this a try. I've had good success undervolting other handsets.

With latest code blue and adiutor app cannot set 650mv for 300mhz and 422mhz, lowest i can go is 700mhz not sure why though. Thank you anyway, I'm trying this out.
Enviado desde mi Nexus 5

It's the kernel the lowest you can go with code blue is 700

So, I managed to overclock my GPU to 2 GHz ("TURBO" Profile) with KonaBess and it's rock solid. Have I been extremely lucky or...?

So, I went on a "boredom rampage" and I've read an article about a guy overclocking his 865 GPU to 865 MHz and reaching Adreno 660-levels of performance and I decided to give it a try and it was awesome.
Problem is, I'm too much of a thinkerer and I pushed the GPU as much as I could. I ended up on 2000 MHz with "TURBO" voltage profile and it's rock solid even on 2100 MHz with the same profile but KonaBess gives me an error if I try to edit the GPU tables after I booted at 2100 MHz.
I even edited the clock profiles to make it smoother, starting from 305 MHz to 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 with the right voltages.
Now, the battery and SoC temperatures are the same, the battery drain is basically the same, some other fellow modders with the same device (Mi 10T Pro 5G 8/256 with Pixel Experience Plus ROM) didn't manage to hit the same clocks, crashing even with 1000 or 1200 MHz, with my file from the KonaBess app.
So, have I been extremely lucky with the silicon lottery or it's just an illusion?
Please ask if you need ANY benchmark or proof. I've been monitoring the GPU clock with Franco Kernel Manager Live Monitoring and the clock is solid at 2000 MHz and the 3D performance has at first jumped and then slowly climbed, especially on 3DMark Wild Life Extreme. Wild Life Extreme Stress Test is stable the temperatures are fine.
Do you guys have any questions/suggestions/requests?
Edit: Here are some 3DMark runs, both Wild Life and Wild Life Extreme at stock and 2 GHz. I use Greenify, my storage is 94% full and all my processes in the background take up 4 GB of RAM and I didn't touch the bus for the various steppings for the clocks, so I believe that if heavily tuned, this could make a difference.

I have the history of all the bench on 3DMark, because I downloaded it just for this. Would that be ok?

it seems fishy, a 1ghz+ oc would increase your fps by more than that.

It doesn't have the biggest of bumps from 900 MHz to 1 GHz or 2 GHz, but still, is capable of doing it and rock solid too.

i don't think your gpu is actually running at 2ghz while you are running a benchmark. going from stock to 2ghz would at least have to give you an extra 20-30 fps in Wild Life.

Not necessarily. The GPU IS running at 2 GHz but I think that the problem might be some diminishing returns where the clock doesn't mean anything after a certain point.

Are you try locking the freq on 2ghz in Kernel maneger ? Set min and max to 2gzhz with performance governor .

I've made various frequency steps. 400, 600, 800, 1000, 1200, 1400, 1600, 1800 and 2000 MHz. But if I change the governor, after I reboot, it will be msm-adreno-tz again. Max frequency is still 2000 MHz and minimum 400 MHz.

Yes after reboot is resets like on every phone you have to check apply on boot and select min 2000GHZ and max 2000ghz GPu freq in tap in FKM and set gov to performance and do benchmark like 3dmark wild life . Like that. And in Smart pack Kernel manager free app is GPU throttle turn that off.
Check box apply on boot and after boot will be apply.
And that you can show improvements of OC

Thanks What is temperature ? Do you game with that or this just experiment ?

Temperatures are roughly the same. I do game with that. On normal games, frequency stays at 400 MHz, but on really heavy games like Genshin Impact, completely maxed out, depending on the scene, the GPU goes to 1.6 or 1.8 GHz and rarely at 2 GHz during some heavy cutscenes. 3DMark keeps it at 2 GHz all the time.

Hello, excuse my ignorance, but I want to learn what konabess is, it's an app or a magisk module, I also have the xiaomi mi 10t pro with DotOs rum android 11 and then I want to play more fluently, could you help me

konabess app is software you can overclock GPU and undervolt.
You need root and that it.

Here tutorial but it old I need make new one because there isn't good one tutorial about it.

This doesn't make any sense. Why would Qualcomm leave so much on the table ?
