[Q] Cant Overclock???

Im getting kinda fustrated here... i tried CM7 and currently on Ice Glacier and im having a problem where when i try to overclock my phone (even if its not so high) it gets frozen and needs a battery pull... i know that some cpu's cant handle frequencies like 1.8ghz, but even at 1.2 / 1.3 / 1.4 etc. i still get it. I switched from smartass, ondemand, and other governers and still freezes... any advice? Or am i stuck with the weakest link??

have you tried flashing another kernel?...maybe another Faux kernel on low voltage or maybe try Grankin v.05 kernel

im using faux right now. ill see if i can find another one thats good to try out
thnx

i always thought that stock voltage was the more stable of the two since thats why i flashed it first when i had this issue... Anyways, tried faux low voltage and cranked it up to 1.8ghz to see how it goes. PLayed around with it so see no freezing yet. but performance was pretty much the same so i tried quadrant and see... i get an average of 1600 so thats pretty low IMO. As soon as i change to ondemand governor... it froze
back to the drawing board

well like im sure you've seen or heard...all hardware is different
so while 1.8ghz maybe slow...going down to 1.5 maybe quick and the opposite maybe true for someone elses phone...they may just totally fly at 1.8 while they grind to a halt at 1.5
so keep messing with it and see what happens...change clock speeds...change up the governors...just dont OC it to 1.8 and think the phone will magicly hit a 4100 quadrant and not have any issues
worse case...flash a different kernel and see how it acts
also on that topic...you said you were running IG...did you run the stock kernel for any length of time? did you try and OC that one?

What Kernel are you guys using on the lastest CM7?

How many .35 kernels are available? I'm only aware of Umaro's and the stock CM kernel. I'm trying to achieve better battery life, so what kernel are you guys using?
So far, using Umaro's, I'm getting regular battery life, nothing special. Haven't tried the stock CM kernel.
Are they any other undervolted kernels available?

There aren't any others so far. Umaro's kernel is really good for battery life, however it's not up to date with the latest kanged nightly from yesterday.

Ahh, I see. Thanks for the info.
What cpu settings are you running?

Right now I'm using a kanged nightly with the "stock" cpu settings of 245MHz min and 1024MHz max, but with the interactive governor. With Umaro's kernel I had at 245 min, 1017 max and the Smartass governor. The smartass is pretty good on battery.

u made all the right moves all i would do is dim screen and keep runnimg apps low.
pimped out g2

btw pyromod 2.0 345 ghz min 1405ghz max on smartass. i fully charge bout 1 a day
pimped out g2

Pershoot released his kernel the other day pretty nice and smooth

Alright I'm sleepy so this will be in rambling form but...
I've tried Umaro's and I'm not sure if it was the undervolting (which I haven't looked into tweaking) but my phone kept stuttering no matter which governor I used. I was using Htcclay's Super CM7 1.8 with cpu set to 245/1113
I also used the stock kernel that's been on CM7 with no problems and average to good battery life (10-15 hours of active use: texting, browsing, few calls, and playing the occasional game)
Most recently I've used Pershoots which I had heard worked great. I myself love it. Almost same battery life as stock kernel but everything felt just a little bit smoother performance wise.
Here's a link to Pershoot's thread:http://forum.xda-developers.com/showthread.php?t=847672

The stock cm kernel in my opinion is finally good enough that it doesn't need changed. I have always flashed pershoots and occassionally others, but it truly does not need supplemented IMHO.

You're running that on Vision? I can't seem to find it for our device.

Stock CM7 kernel here. I run 245/806 Interactive with automatic brightness. I've found that when wifi is on, keeping the cell radio @ 2G only works wonders. Wifi is set to sleep on screen off, but not when plugged in. 1 day 7 hours on this charge so far with 23% left. I would consider my use light to moderate.

I'm wondering where can I download the Umaro's kernel. I check out his github (https://github.com/umaro/htc-kernel-msm7x30) only to find out that the source is available.

Trinity kernel OTG crash/freese bug

Hi
Sorry cant post in the development thread since i just joined.
Using TS1700-GPUOC-4.1.2-mr1-fr-ALPHA12 with CM10 causes Nexus 7 to Freeze/crash and reboot when you remove a USB pen drive or 2.5 harddrive that is connected with a OTG cable. It happens if you do a dismount from settings/storage or just pull the cable OTG cable out.
Otherwise its a very good kernel for Nexus 7.

Finally! I could Kiss you!! I wont don't worry.... at least however a manly high five will do. I am having this issue since using the Trinity Kernel and like an idiot never once though it was the Kernel. Strange how the units will still turn off even if you just plug and unplug in the OTG cable with nothing plugged into the cable itself. So we think it is the Kernel then?

Yes, 100% certain its kernel related.
When you run CM10 updater from inside CM10 and a new nightly build gets installed it removes Trinity kernel and install the default CM10 kernel and that makes the problem go away.
After you flash Trinity kernel back you get the freeze and crash/reboot issue again.
If you use this Kernel, please contact morfic. check his site below for email and other contact information.

Thank you Cazrack. I will email him now, I can imagine he will be inundated with emails
Another two quick questions "sorry" with Trinity, do you use setcpu to overclock or do you find the kernel gives you all the speed you need? secondly have you had the issue of the unit turning off on an overnight charge? I do not do this normally but I fell asleep with it plugged in and found in the morning it was turned off, when I turned it on it was at 100% so thought is might have turned off as a safety feature but just wondering if you experienced this or heard of it happening?
Thank you again for you help.

The same thing happens to me with the Trinity kernel but it also happens with LeanKernel for 4.2. It did not happen with LeanKernel for 4.1.2, so I don't think it is just a kernel only issue. It doesn't happen on the stock kernel, M-Kernel+, or Franco r30.

Cheers for the response, always good to know its not the hardware . Defo a Kernel issue, I have emailed derkernel.com, I am sure we should have a fix soon, otherwise it aint that much of a big issue.

I keep the stock clock speed 1.3 ghz but I use setcpu to set certain programs to scale to 1.7 ghz.
For example webbrowsers benefit from 1.7 ghz in faster loading and smoothness.
overclocking for games i prefer to run cpu stock and have my gpu overclocked to 600 mhz.
stock gpu is 416 or 418 mhz.
cant overc to much during long gaming sessions since it get to hot and gpu oc give more than cpu.
when i used franco kernel r25 the power off thing happend to me too.
only 1 night during charging but i flashed a new kernel after that.

Ah I see I have done the same it works very well. However you mentioned overclocking the gpu to 600mhz how is this achieved? its not an option in setcpu, suppose the programe is called setgpu
I think I will stick with the the Trinity as the OTG restart is not that much of a issue really. I am sure derkernel will have an update soon.

yes you can OC the gpu for better gaming fps on some kernels.
for example Trinity kernel and Franco kernel allow this if you use franco.kernel.updater from google play store.
i have tested 700 mhz but but during long gaming sessions with games pushing the gpu hardware like spiderman it just get to hot.
484 and 520 mhz is considerd very safe from the information i gatherd.
600 should work even for longer gaming sessions but the device will be warmer.
650 i will test this but im sceptical about long gaming sessions.
750 some crazy people run this....
at the moment im using cpu gov ondemand in setcpu with value 50 in cpu scaling.
have you tried the elite kernel? 1.8 ghz cpu 650 mhz gpu..

Okay I see it comes full circle, I will give it a bash.
The elite was going to be my next kernel... only reason for using Trinity was, I was advised to do so as a first try. It might be the next step to get rid of the OTG restart and of course the 650 mhz gpu stock oc. Have you tried it or going to try it?

is it supposed to work with cm10? ive tried to flash it but it didnt seem to flash in good
because trinity animation still showing after flash... but nexus isnt booting up.
no problem just boot into recovery and reflash trinity kernel or a cm10 rom.
any clue?
prehaps reflash elite when you have updated to a 100% cm10 nightly installed.

Sounds strange did you delete the cache? As I had that issue originally? I am just using stock ROM tbh as it seems to be the most responsive at the moment but I have not tried them all obviously
Suppose we best keep on keeping and seeing if the smart devas can release a fix.

I think i did, but i will try again. Could be that extreme kernel is not compatible with cm10?
I would like to try to OC cpu even more up to 2 ghz would be intresting but i dont think there is such a kernel to download.
Once i reach 10 posts ill post in XDA Trinity developer thread

Undervolting the GT-N7000 for better Battery life

Hey there ,
so i wanted to share share my awsome Undervolting results with you
At first im running on Chasmodo's latest CM 10.1 i really appreciate his work ! I use the latest CM 10.1 Kernel.
With his rom and this voltages u find under this introduciton text i could get nearly a month with Standby time
(without doing anything , Wlan turned on , Data off) i attached a screenshot (29 Days and 5 Hours sorry for the German language)
Every day i plug my N7000 out from the Loading station its 5am on 3pm i lost 1%.
to change the Voltages i use SetCPU (full version)
1400 MHz
1200 mV (Stock: 1350mV)
1200 MHz
1100 mV (Stock: 1275mV)
1000 MHz
1000 mV (Stock: 1175mV)
800 MHz
925 mV (Stock: 1100mV)
500 MHz
900 mV (Stock 1000mV)
200 MHz
800 mV (Stock: 975mV)
So i dont know my Voltage group sorry guys , if this values are not working just go in 25mV steps lower from your stock voltage
until the CPU gets unstable or crashes than u know that u cant go lower just do this with every clocking !
I also used this voltages on XXLSC Ultimate Rom with the HydraCoreNirvana Kernel i had fantastic results too but not that good like i get with the Asylum CM 10.1.
PS: Just this Voltages wont give you very good Battery life if your Rom / Settings is/are eating your battery. If you get better results with
lower results (stable) just go ahead and post it but im sure this values are nearly the lowest stable u can get
Code:
Its [U]impossible [/U]to hard brick your device with Undervolting , you only could get a soft brick if you use (Set on Boot) and your voltages will crash your System after boot. thats easy to fix just after the phon booted up fast go into SuperSU and delete the root rights for your Undervolting tool.
Thanks for Reading and if i you liked this push the Thanks button =) !:victory:

Thanks man

I think you should say which Voltgroup (A, B or C) your note is. Because those freq are really low (I think too much low for my note, that's voltgroup B).
Do you remember which voltgroup has your note, when you installed hydracore kernel?

Better i would buy a spare battery rather than spoiling my devices performance. We arr not in 1000BC with no electricity. Sure every one can charge a spare and can switch it.

Hey there i dont remember never looked at the Voltgroup sorry so there is no other way to view my Voltgroup ?
Btw just try the voltages without autostart and u will see if your system reboots or if it works if not just go in 25mV steps higher :highfive:

I cant get your argument my performance is the same speed while im gaming browsing same performance than before .. no impact , drops .. a spare battery ?

It's a feature of the hydracore kernel only I think, because its read a particular value (something about mainboard and/or cpu) and the kernel automatically apply dedicated undevolt values. You could see it in system information, where hydracore kernel is detected. Without it, I think you can't do anything :/
Anyway, sincerely I remember some time ago I tried to lower my already undervolted cpu voltages, and I got freezes. I will try to go lower a bit, hoping it will works. A very important thing, is not only the lower battery drain, but also the lower cpu temps.

I bought rom toolbox full sometime ago, when there was sales. If I remember correctly, there is a section relative to the cpu control, but I don't remember if it was undervolting capable also. You should start to search it from there (I'm sorry, I don't have the app installed anymore, so I can't help you properly... In case, use voltage control app)

What do you mean by Rom Toolbox doesn't have voltage control?
Tap kernel tweaks, then any frequency and you'll find a voltage slider in there.

Maybe it depend from the kernel I'm using now (philz 3.99 on BurtRom tw rom) but I can't able to do what you said. I checked on rom toolbox pro again, and I didn't see any uv feature. Just goverors/kernel tweaks (like vm or fs features) or profiles management... Nothing else.

I don't know - I am not sure if Undervolting could hard-brick or damage the hardware but back then running GB roms I had undervolted FM Kernel and there was trrrr trrr trrr like sound from my Note.
Be careful.

I have to do a custom rom just to see if its all true....otherwise am not interested at all in undervolting my phone. Hope its true...

never had any problems and just logical cpus could brick if you give them too mutch voltage , if you give them less voltage the system only can crash your sound could have been beacuse it crashed so really u cant hard brick your device with undervolting ... maybe a softbrick if your unstable voltage settings are on autostart.

Hey there , you cant uv with Philz kernel just read his thread check his FAQ there hes writing that hes not supporting
oc/uv its just a repacked stock kernel
use HydraCoreNirvana but when you download the kernel check that its the OC version if not than you cant change your voltage like with Philz kernel.

You can you can
Just use tegrak ultimate Overclock app. I bought it because I think it's the only who give you the possibility to Undervolt the gpu also. Initially, philz kernel wasn't supported, but now it is. I undervolted my cpu setting the values that I had using the hydracore kernel oc. And today I lowered them of another - 25mV also. Everything works nicely until now

Nice attitude you are showing there. Oh, there is plenty of power, let's waste.it! Really, that kind off attitude is definitely going to make the world a better place
What's more why do you think undervolting does influence the performance? It only influences the power consumtion and if you go too far it does render the phone unstable. But it certainly does not in-, or decrease the cpu's performance.

Yep tegrak definitely does the trick with PhilZ kernels. I have been using it for at least 8 months now and my phone is undervolted too. Only the highest cpu state is overvolted because I overclocked it to 1552 MHz instead of 1400.

I would love this kernel under ubls4 if it has a proper exfat support. Until this is not fixed like philz kernel, I can not test or try

Please explain why you overvolted AND overclocked the highest cpu state. Doesn't this shorten your batteries performance?

Did you changed cpu governor or something else (like screen off profile to reduce CPU) to achieve 1% battery loss at 3pm?
And was that with mobile data on?

Please explain why you overvolted AND overclocked the highest cpu state. Doesn't this shorten your batteries performance?

I overcloked the highest cpu state from 1400 Mhz to 1552 Mhz because I want more performance. And because my phone became unstable with the 1552 Mhz and the standard voltage. So now my phone saves energy when the lower cpu states are active and it has a bit of extra power at the expense of battery life when it needs the most processing power. All in all that gives me better battery life than with stock settings and a snappier device when needed. For me this is the ideal solution.

Galaxy S Android 4.4 Unstable overclock

Hi there,
I want to get the most performance out of my old galaxy s but i have a slight problem with 4.4.
I came from Slimbean android 4.3 on 1.2ghz because it worked really slow and gave me alot of problems.
I first flashed (After full wipe) to Mackay 4.4 rom but whatever govenor or sheduler i am using it crashes everytime after a minute or so doing some simple tasks from the slightest overclock (1.1 ghz).
So i flashed to CyanAOSP (full wipe) to see if it would fix the problem but the problem still exist on this rom :c
Is there something wrong with my device?
Greetings,
- Merlin

Taking the phone to pieces and applying thermal compound to the chips gave me another 100Mhz. (rock solid at 1200Mhz when 3D gaming etc). There are 2 chips underneath the motherboard, and if you remove the sim tray from the board there are another few under there. I did them all. Be very careful if you're using Arctic Silver. I would have preferred to use the cheap white stuff but I didn't have any. There is a thread if you search for it with instructions on how to do this if you need it.
And with overclocking there's an element of luck. There are variations in the manufacturing of the chips themselves which can make your particular phone good (or useless) for overclocking.

But why could it do 1.3 ghz on android 4.3 easily? I think it has nothing to do with heat atm.
Because sometimes i can run antutu for 2 times in a row before it crashes. But sometimes it crashes instantly when i press the start button.

It's kernel related issues. I managed to clock in at 1.6Ghz rock stable on CM 10.2 but likewise, a 1.2Ghz overclock on 4.4 is giving me very rear soft reboots

Ah ok now that i know that, its probably going to get fixed sooner or later

Interesting. Mine is stable at 1.2Ghz on 4.4, so I'll be trying to push it a bit more when I get new kernels. I put Arctic Silver on all the chips the other day, even the ones under the sim card tray so hopefully that will help it. It has defo done something because my phone was unstable at 1.2Ghz before I did it.

I just flashed to semaphore kernel on mackay rom and it is fully stable on 1.3 ghz atm.

Is there a 4.4 semaphore kernel?
Sent from my GT-I9000 using Tapatalk

Guys , every kernel has its own custom voltages for over clocking . just use an app that controls the voltage (you can find one in play store ) and increase the voltage step by step until your phone is stable. For example : on Mackay I can't over clock not even to 1100 MHz with stock voltages without the phone rebooting after a few seconds but on Semaphore I can oc with stock voltages up to 1200MHz and its stable . on Mackay I messed around with higher voltages until I found the ones that my phone is happy with and I could oc up to 1300 MHz stable after that.

Yes there is , check the Semaphore thread for 3.4.0
Sent from my GT-I9000 using Tapatalk

I didn't realise that voltages were set in a kernel. Thanks
Do you know what voltages I should be using for a 1300 or 1400 overclock? I'm sitting stable at 1200 at the moment, how much do you think I should raise the voltage to keep it stable with another 100 or 200 MHz increase?
Edit: I'll try the 4.4 semaphore kernel
Sent from my GT-I9000 using Tapatalk

I personally use these settings:
Frequency - CPU - Int
1000MHz - 1225 - 1100
1200MHz - 1300 - 1100
1300MHz - 1350 - 1100
1400MHz - I've never got stable 1400MHz OC :/ (I think 1400 1150 should be right for most devices)
Optional:
1100MHz - 1250 - 1100 (some kernels have this step)

Thanks again, that's me running rock stable even under gaming at 1.3Ghz. Not tried 1.4.......yet lol
Why is there two voltage values you gave for each clock speed though?
I used setcpu, and set the first value. I'm not sure what the other value you gave is? GPU voltage?? Thx

Second value is internal voltage (mostly used with LiveOC to stabilize as it gives voltage to GPU and RAM). With normal OC it should be at stock (1100mV). Some apps, like NSTools gives you opportunity to change those.
Normal OC affects CPU, and liveOC CPU, GPU, RAM, so it's more likely to be unstable. I can't reach 1100 on LiveOC, but on normal I have 1300 easily.

Ah well i am using stock voltages from semaphore kernel and 130% live oc. It is fully stable atm.

Heh there are no two same devices. One overclocks better and one at all. There are devices which can't be overclocked. It's just luck you have with your hardware.
