[Q] Overklocking and kernels

Hi!
I've struggled with my Incredible S for a long while now. Asked questions here and so on but haven't really got any answers.
Things went something like this: My mate rooted his and my IncS same time with Revolutionary. We both installed ARHD and overcloked to 1920mhz just for the lulz. Everything went just fine for a while for both of us, but then I decided to restore my apps sms etc from the stock rom with MyBackup (or what ever its called). Restore failed at some point and I needed to flash ARHD again.
Ever since my CPU hasn't been able to reach 1920mhz or anywhere close ever again. I've been flashing dozens for ROMs now and only few of them could be O/C to 1600mhz. Some freeze at 1152mhz instantly, others can be stable for few minutes and then crash.
My mate is running CM7 with enki-v0 kernel at max O/C without any problem. I tried CM7. It started to become unstable with default O/C after few days and I had to siwtch back to some Sense Rom that worked at normal O/C.
Why some kernels (forexmpl Quattro beta 6) allow me to O/C at 1.6Ghz and others freeze just at 1.1Ghz? (Affinity,Unity,Niks trinity, Quattro betas 7- Rc3)
And why my CPU can't reach the 1.9Ghz anymore? Could I **** something up and the CPU is broken now or is there something wrong with my rooting?
TL;DR Only few Roms and kernels allow O/C and with them its a pain in the ass cuz of unstability, why?
- And I'm not looking for solutions like "Flash to stock". I know how to get it stable, but then again 1Ghz stock ain't that cool.

How are you overclocking? I've never used CM7 before, but I do use SetCPU. Every time you flash a ROM you need to go into SetCPU and Device Selection and then Autodetect Speeds Recommended. Either that or you can try selecting Show Other Frequency Sets and pick your processor from there.
Basically the only thing I can think of is that your processor is not being recognised correctly.
BTW When you say "Everything went just fine for a while" how long is a 'while'? The only reason I ask is, how sure are you that running your processor smoothly at 1920mhz for that period wasn't just a fluke, and your phone (for whatever reason) cannot normally run at that speed? From what I understand, even phones of the same model can differ as to the speeds at which they can be overclocked. Maybe you just got lucky the first time, and now that lucks run out?

Dont you think that 1.9 ghz is a bit dumb... You might (have) damage(d) your cpu by doing that. If i would oc my 3ghz pc to 5ghz without cooling modification i would fry it in half an hour.
I mean cmmon use your brain. Oc it to smth logical like 30% (1.3 ghz) and you will not have such problems .... Sorry, but that just sounded plain stupid to me

I use SetCpu and every time it recognizes automaticly some speeds and I use them. The manual setup is bit beyond my knowledge.
The while was something like 3 days or so. Hard to remember. But still wayy more than like few minutes. I will try to set SetCPU manually, thx!

I know 1.9ghz is dumb. I used it back then only in short bursts. Usually scaling "interactive" between 245mhz - 1.5Ghz. Now even that is too much for most kernels. I thought that the freeze is caused by the CPU protecting itself from getting damaged or something, but not sure.
Still if the CPU was damaged, why would Quattro beta 6 kernel run at 1.6ghz without overheat or anything and RC3 kernel freezes at 1.1Ghz when try to load something more than homescreen..
I would use beta 6 kernel for quattro, but it does not support wifi in RC3.. Virtuous team made some changes to kernel at beta 7 and I would love to know what changes..

From the source code I don't understand a single thing
and...
"New kernel V5 (new acpu table, updated GPU drivers)"
What is acpu table? GPU thing I get, but hardly it can prevent from O/C?

Your stable OC

Since every Ace is different and I just started messing with OC, whats your stable frequency? Mines is 844 D:
Sent from my GT-S5830 using xda app-developers app

Mine is 864MHz at 906 it turns off after 10 mins and is verrry HOT!

906mhz with very minor excess heating :laugh:

Mine is 921. it drains battery too fast but the speed is awesom
Sent from my GT-S5830 using xda premium

Mine runs on 844Mhz and works smooth. Gets a little heated when playing HD games (NFS Shift) otherwise stable.
Battery usage is kinda ok as it is supposed to drain battery at OC

Aww mann I'm jealous of all you guys running on 900 D: mine reboots when I set it that high. Then freezes at 883 and apps crash at 864. Can that be changed with the kernel? Or is it still Ace specific?
Be very careful when OCing though. It can fry up the internal hardware.
Sent from my GT-S5830 using xda app-developers app

Mine is pretty stable at 902Mhz... Very little heating and fully stable

My stable OC is 960Mhz.
979 = only last for 1 hour....then reboot
998 = last for 2 min(playing games) and reboot
1000++ = reboot after selecting those frequency

921Mhz for me
This was sent from a Galaxy Ace.

So any of you guys think this is kernel related or just Ace specific?

i think its ace specific....
i mean....2 same phone using same kernel, but different OC limit???

None....Its CPU specific.Its just like buying things from a store,sometimes you get faulty products,sometimes you get the best.BESIDES,some say that our CPU is factory OCed,but no one is sure about it :/ And,its just an armv6 obsolete **** We are still stuck in the 19th century

Oh okay. I thought so. But doesn't switching to different kernels alter that pattern? Or the kernel simply allows the phone to go that high?

I have used the cf54 or 84 I think Kernel and [email protected] kernel and I was able to overclock until 1.25Hgz on the latter though I was unable to take it to 844 on the stock one.
Hence I would say that the Kernel would play a role in the OC limit of the ace. Having said that, I might be incorrect as I did flash custom ROM along with [email protected] which could play a role in the OC factor too.
Someone with moreprecise clarification ?

I don't believe you. The Ace is already OCed from factory. It can barely reach 900Mhz as it is and only for few.
But if you did, I'm surprised you're still using your phone to this day without a fried motherboard.

Partly.Kernels like Cf-root are basic kernels,even Chainfire himself says so.It just takes him 5 minutes to build a cf-root kernel(What he said in an interview)..Kernels to "some extend" define it but the final decision-maker is the CPU.

I don't think its true.....Because Ace is clocked at 800Mhz,that too factory OCed from 600Mhz.Also,our CPU is armv6,so its "PRACTICALLY" impossible to OC to such a high limit.

I can get 902 mhz on CF root,But on delano 998 Is somewhat stable.so yes kernels play a role in this.

Armv6 doesnt make a difference.E.G. look at SG3,armv6 cpu but almost every SG3 reaches 1200 mhz 100% stable(Few reach even 1400).1.25 ghz=1036mhz,which is available freq. in ketut's blackhawk kernel so MIGHT be achievable.And Ace's cpu is 'turbo' msm7227,means can maintain 800mhz clock for longer time with less heat/at no extra voltage, not that it is oc'd 800 mhz.But I can be wrong

[Q] Thinking about buying the 4XHD

Hi everyone, I'm thinking of buying the 4XHD as I can get it for a very good price (far cheaper than the one x or S3).
I have a few questions about the phone though, and reading the forums brought up more questions.
1. Are there actually any Kernels or Roms for the phone as I cant find any in the developer section and has the phone actually got a unlocked bootloader as some people said they had, others they hadn't.
2. What are the chances of the phone either getting an official 4.1 update or getting an unlocked bootloader (I can't tell if it already is) with which a custom 4.1 ROM can be flashed onto the phone.
3. How well does the 4XHD actually do in games as in my research I found one thread about lag and that is all. How do games like Nova 3, Asphalt 7 and Need For Speed: Most Wanted play? On the nexus 7, nova 3 (without custom kernel) was really laggy and I'm wondering how it will perform on the 4XHD.
4. Secondly, without a new Kernel being developed, is there currently anyway to overclock the GPU in the phone as I have read on one post about changing the kernel governor (here) or is this just using SetCPU?
5. Regarding SetCPU, does it help out with gaming performance the same way it helped out the One X (or was that purely because the one x used the Ondemand governor, which performs worse than the Interactive governor of the stock 4XHD)?
Thankyou everyone for reading this.

There are no Rom or kernels but u can under clock the CPU and i use no frills CPU to have the phone running. On 760 MHz and 51 and it performs well for gaming I just put it on the highest and no lag. I would install a CPU app because it seems that without it on it when u listen to music it skips quite frequently with screen of but with an CPU manager it is fixed even on 51 it won't skip. Other then that. I do not have any of the lag other report. It is a very capable phone. I would not install setcpu it does not seem to stick and work right. I tried to set it back to 1500 with setcpu and it stopped at 1ghz but no frills CPU works with no issue. I hope that helps u somewhat.

Thanks, if you are using Nofrills and you set the min CPU clock higher does this actually translate into better gaming performance (does it change the governor and the GPU performance ) or is it just better for saving battery life when you don't need high performance? Do you actually need any extra speed or is it fine in games - the one x, even taking into consideration the larger user base, there seems to be far more laggy games complaints.

Yes I set it too 1500 min and max and i have no lag I also select governor power no lag. I hope it works for. Don't forget after done with gaming to change the CPU back to how busy want it and also not to use power because then I always stays at the possible highest CPU u selected.

For gaming do performance otherwise do not. And the hox seems to still have a less optimize tegra 3 supports in it. The 4x hd is faster.

Also u might wanna consider when playing games to like really turn everything off so u want sync with anything or text really I know it sucks but turning of dta and cellular and then playing games will make for no lag also make sure u pretty much cleared all running apps as well.

Ok Thanks, that basically answers all of my concerns. I,m not too sure about getting 4.1 (Custom ROM or not) but it isn't that necessary. 4.0 is still great.

[Q] Best Galaxy Ace Overclock Frequancy... And something else thanks

Hey guys
I know their probably another thread out there with this in it but... Yeah. But go ahead troll me lol, im still a bit of a noob.:silly:
Anyways, i have a Galaxy Ace s5830. I have Beats with smooth sense ROM. I had it upto 883MHz Yesterday but after i turned it off then back on ROM Toolbox reverted it to 806MHZ. 883MHz seemed a lot faster even though some people get theirs close to 1GHZ
My phone afterwards rebooting had issues such as the phone becoming un-responsive when i was even doing nothing (maybe the overclock to 883MHz had some short term effect?) But the phone seemed fine after safely turning it off then back on several times. Still works perfectly i got scared when it started to become un-responsive. But it works well now i have also used pimp my ROM, and the scripts work like a charm. Especially the call quality one (it uses bravia engine or something?). But with pimp my ROM wi-fi and network tweaks it completely broke wi-fi saying wi-fi connecting... Then saying under the network name 'Error'. Dam it took so long to get the IP address then said error like i said lol
At the frequency 883MHZ the phone seemed stable and faster than ever before, i did change it in small increments
So just wondering, what is the safe and most reliable frequencies to set it at? I currently use 225Min and 806 Max. With the userspace governer.
I know the terms of ' Safe ' and overclock don't mix (sorta like water and my dads S2 :crying: ).
Im also considering buying a 2450MAH battery from ebay for about 5.99 AUD. Any suggestions on should it be okay and better? But i mainly would like to knwo about the overclcoking lol.
So yeah, basically what is a good frequency to set it at? Is 883MHZ okay? Am i going to fry it out or completely brick or damage the phone or cpu if i set it at 883MHZ? Would love to buy a new phone but i need to save im only 14
So yeah please help me and you could help others too. Please be welcomed to troll me
I plan on having this phone another 3-4 Months before i consider buying the S2 or Galaxy note when their cheap (like really cheap)...
Like i said please help, and feel welcomed to troll me when you do help :highfive:
Man i feel like a Rebel when i overclock

That battery is a fake and has been confirmed as such. If you want a higher cap. battery get a 1500mAh or 1600mAh. I don't like messing with the clocking, good luck to you.

Thanks

Right now I am just using the stock one. I personally wouldn't change my battery to anything other than stock, but people have reported that 1500mAh or 1600mAh work well. I wouldn't use anything that has a higher capacity than that though. Also, if it's very inexpensive it's probably not real.

Clocking actually goes on the rom. I've seen people having OC over 1gHz & still stable with the mad kernel but I gave up clocking as I didn't see much of a difference & also underclocking started giving me FCs on some heavy apps while it was all fair in the unclocked state. And again, there's no such thing as a best frequency. You find your own values. What works well for him might mess up your phone rebooting all by itself. Stock batteries are always fine & they also keep you under warranty. Anyone ever wondered why the phone manufacturers didn't implement clocking as a part of it ? Stability is the word. I've seen here, I've seen there. East or west, stock is the best ! Try keeping as close to stock as possible, just to have that extra touch of safety & stability

Hello all.
I was reading this thread and became interested in overclocking. In my case my device is:
Samsung Galaxy Ace GT-S5830L (labeled as GT-S5830 by CyanogenMod)
CyanogenMod-7.2.0-cooper stable (Android version 2.3.7)
Kernel 2.6.35.7-perf-CL882825 ([email protected] #21)
I was checking in CM settings -> Performance -> CPU settings that I could adjust min and max clockspeed, but in max frequency the maximum one is the same processor's speed, 800 MHz. So my kernel doesn't support overclocking.
After a search in the forums I found there are plenty of custom kernels for this legacy device. But I'm relatively new to the kernel world, so I wanted to ask you for advise. What custom kernel could I try for my device for overclocking? Or King Android, what custom kernel are you using?
It'd the first time I do the overclocking stuff, I'd like to try it to see if some higher quality mp4 videos (which are run by MX Player only in software acceleration) can run better, as well as some games and emulators.
I'm also kind of a noob as you can see. If you want to troll/scold me...
Thank you all.

Hi you can try FireKernel or BlackHawk kernel. Use the search function to find them easily. Both supports Overclocking and are made for CM7. [MAKE SURE THEY SUPPORT YOUR S5830L]
At the moment I'm with Democracy ROM which is based on unofficial CM7 and I don't really feel the need of overclocking. It is all smooth with firekernel at
Min 245
Max 806
Governor smartassv2
Sent from my... oh wait, who cares?

I did my search.
Maybe I forgot to mention I haven't installed a custom kernel before... Does the kernel come as a file itself, or along a CM7 custom rom? And if it comes as a file itself, how can I install it? I already mentioned what CM7 I have installed. It's the "official" stable one.
Would OCing help to improve videos and games performance? i.e, faster, no lag...

You can set it to whatever your phone can handle. Mine can't go past 844Mhz otherwise apps start force closing and such. If your phone is completely stable at 883Mhz then you're good.
As for the battery, no. It's a fake. Buy a 1500mAh like I did. Works like a charm and it brought 3. Lasts a little longer and it's really amazing. Had it for a while now. Still have one in the pack, only been using 2 when I don't get to charge my phone. Really handy.

OCing helps the phone over all. But remember, without much free ram, OC won't really change much. You need a balance of ram and CPU. Like me, I use swap and OC to 844Mhz. Even if it's a low OC, it's still better than nothing.

1. @SuperAce609: I have 104 Mb free RAM out of 278 Mb total RAM. Mine is Galaxy Ace S5830L with CM 7.2. Would OC work for me? Up to what frequency?
And how can you have 600 Mb of RAM? Is your device really an Ace?
2. There's still a doubt I haven't been able to find out myself: does the kernel come as a file itself, or along a CM7 custom rom? And if it comes as a file itself, how can I install it? I was suggested FireKernel or BlackHawk ones...

Any help?

1.- Every Ace is diferent..some Ace's can go up to 960 Mhz while other just 844 Mhz, the thing is: try it yourself overclocking in small jumps. Swap is a small amount of memory of your SD card, that Android use it like if where RAM, but decreases SD card life...
2.- Some Kernel came Built in on Some particullary ROM's but generally cames on a CWM Flashable zip; FireKernel & BlackHawk are specially for CM7; In my opinion FireKernel is the best... And there are others like Battery Extender Kernel or NimsKernel but these Kernel are only for Stock ROM's...
I hope you find useful my info...

Thank you, Blake2893.
Then there's just 2 doubts left, if you don't mind.
There's a fair number of custom CM7.2 roms with FireKernel in the developer forum. Is there one you or someone else could say is the best in terms of stability and least number of bugs? Or is that something I should test myself in the S5830L?
The Ace S5830/S5830L has 278 Mb total RAM by default. If I understand well, you're implying I could modify SWAP partition in order to increase RAM and, probably if lucky, with this make OC work better. How can I do that? Do I also need a custom kernel/rom for that?

The best stable Roms so far are the stock GingerBread based ones... but if you aks me about CM7 there a few like Apocalypse rom(ICS styled ROM) with the FireKernel that suports swap I think...
and for Swap you only need a Kernel with Swap enabled and a SWAP Partition on your Sd card...

lets see im fine and stable with 979 mhz without reboot for 9 hours
overclock is depend on your hardware

best over clock freq.

So yeah please help me and you could help others too. Please be welcomed to troll me
I plan on having this phone another 3-4 Months before i consider buying the S2 or Galaxy note when their cheap (like really cheap)...
Like i said please help, and feel welcomed to troll me when you do help :highfive:
Man i feel like a Rebel when i overclock

The best and most stable overclock freq. is actually 906mhz-864mhz. It works like a charm mate! Try it.

Using CPU high frequencies is not recommended, your device's life will be reduced considerably

Good workaround (Kernel/Firmware) against overheating?

Hello guys I got some huge problems here.
I recently switched from my Z2 to the Z3+ and actually like the phone but the overheating is insane and especially kills Pokemon Go through CPU throttling, which runs smoothly on my old Z2 .
So far I am on 253, cleaned it up and tried a self modified and the zach beta9 Kernel and and runs quite bad on both. Is heating a lesser issue of 224? I actually do not want to reflash the whole system to 224 just to find out it doesn't get better.
Also is there a way to undervolt/underclock? I can change settings in Kernel Aduitor but I have the feeling the phone doesn't really care.
Help much appreciated - thanks!

Try Zach beta 8 kernel. Limit max cpu frequency by kernel auditor.
Still it's only your Goodluck if your device cools down. It's a bitter truth about this model.

Do you have a clue whether 224 or 256 make a difference?
I will try beta8 and report back.

no there was no thermal improvements between these builds, dont flash your system back
but do underclock and tell us the results!
Im also affected by your exact problem

Try this kernel, seems promising. I haven't tried it since it doesnt have twrp.

Edit: Today I have flashed 256, haven't found any improvement. As per my experience 256 haven't brought any noticable change.

**** posted twice and dont know how to delete

Thank you for the replies!
Tested zach beta8, didn't help. Now I am testing http://forum.xda-developers.com/xperia-z4/orig-development/kernel-om5z-kernel-t3421630/ as suggested and if that doesn't help much also with http://forum.xda-developers.com/xperia-z4/general/kill-overheating-flash-zip-t3421782.
And Stamina Mode helps at least a bit.

Statusreport: It always runs bad. But best at the moment with root patched Stock Kernel (253) and that underclocking zip. Although I think that underclocking doesn't really help at all.

What are your temps? When does it start to throttle? Done any thermal-conf configuration to allow more heat?
---------- Post added at 21:03 ---------- Previous post was at 20:58 ----------
I know that @Trilliard has a very good and stable cpu governor where he has disabled two of the little and two of the big cores, this helps a lot if you underclock the remaining 4
Here are his files:

UPDATE: Added my edited files used to apply CPU tweaks (cores down clocked to 0.9 and 1.2ghz, two core disabled, tweaked cpu governor, power and others mods) and these files located in etc folder. Replace them and set correct permissions then reboot.

Actually I didn't know about this combination - I will try it thanks!
Do you know about a thermal-conf? Actually never tried one. The phone gets hot indeed but I still think there might be some space before it actually melts.

Thats what i thought as well i have my own here, its based on another persos post, but i dont remember where...
Anyways, his camera mod worked, but cpu throttle was not tampered with, and it caused a very unbalanced throttling... Ok yay i can use the camera linger and fluently, but when i exit the camera app, i cant use the phone couse its runnig at 348 mhz...
So i i did some modifications to it cpu never get under 840 for little cores, so your phones menues end web browsing are always safe from performance drops.
I made it to be able to play Pokemon go, and achieved a lot better resault than without any changes.. still prefer playing on my shield tablet, but if i dont have it around when theres a lot od pokestops nearby, then this will work for me.
While playing Pokemon go it does not go over 80 degrees, but using snapshat it can get to 85, so dont use snap for to long
Let me know if it worked for you!

Oh nice! Thank you a lot! I will totally try it out directly when PTC comes back alive. X)
What kernel and governors do you use?

Im using stock kernel, may switch to another soon. Im using stock bcause of batterylife and idle power consumption
Im using the governor and cpu modifications in this post ; http://forum.xda-developers.com/xperia-z4/general/dont-custom-kernels-want-to-avoid-idle-t3409647

Hmm. Still runs ****ty.
Can anyone give me a short guide how to edit thermal and governors?
According to my observations the phone gets hot and then cold. I think the throttle is more aggressive and needed and I want to make it less aggressive.

Update:
I made my own modifications to the thermal engine. It is pretty bad for battery I guess but I had a very good expierence playing Pokemon Go with it today. Yes the phone gets hot. Like it doesn't drop below 70°C while playing and regulary hits 80°C but it works good. No dark screen, no 0 CPUs downclocking. So far it's fine for me, maybe I get squeeze even more out of it.

Done any other modifications to your file for a while? Or is it working good for you now? What's your SoT?

Still working good for me. Not sure if I can really squeeze out more and as long as it works at the moment I do not have a good motivation to try anything else.
No idea about SoT. Always running around with a powerbank. Probably bad, it is not designed for good battery life.
