Another crack at an overclocking app?

For what it's worth...
no2chem has an app he's working on that suppose to overclock the TP to
800mhz.
http://www.nuerom.com/BlogEngine/post/2009/09/06/Touch-Pro-running-at-800MHZ.aspx
I'm not endorsing attempting to overclock anything. The last thing I ever overclocked what a celeron 300, to 450Mhz back in the day LOL, but, for you
hard core types, might want to head over there and read the thread. THE APPLICATION IS NOT AVAILABLE to download yet, I suppose he wants to really make sure your TP does not burst into flames, or cause a rift in the time space thingy

I read through the whole thing. It looks very promising, but is in its starting stages. Hopefully we can see something good come out of it. If we pick up a few hunderd MHZ, im sure it will greatly help the phone out.

Yeah, I've been following the thread also. If they can get it to work...I'm thinking it would be a trade off. Yes, I'll bet anything these chips are a bit underclocked, but, I'm also believing they are underclocked to remain stable.
Plus, anytime you run one over the specs, it just has to have a marked decrease in battery life, and it almost has to heat it up a bit. Those electrons can only run around inside that tiny package so fast before they heat up

I tried the app 2 times on my Fuze running 6.5 Energy Rom. Crashed everytime I tried to run the program. Gonna wait for the finished product to see how it turns out because the "test version" does not.

Ok so why in the world would anyone want to speed this little Gem up?
Running an energyrom i can run AD2P plus read a book or surf the net fine (hell ive even logged onto one of my webhosts from it) without any lag or speed trade off.
Isnt this just going to kill battery and heat the thing up?

you cant play games like quake and tony hawk with default speeds.. overclocking will enable u to play those games without a lag

[Q] Randomly resetting N1 - possible solution

I just bought a nexus one with the old resetting issue that seems to have come up a lot.
I've been stress testing the phone (using StabilityTest) and found that the sure way to get it to reset is to heat it up, by charging it, stress testing for a while (usually a few mins), putting it on a hot water bottle ect.
The temperature in these cases usually gets to around 30 C before it dies.
I put it on some frozen milk and sure enough its been stress testing for half an hour with no problems - the temperature sticks at about 15 C.
I'll try opening it up and cleaning everything I can with isopropanol. I figure maybe there's some gunk preventing proper cooling?
Any thoughts as to what else could be causing this?

Might be defective or degraded CPU.
Heat slows down electric signals, and the CPU is built to withstand a specific amount of heat without failures. If in the manufacturing process somewhere in the CPU there appears too small (physically) semiconductor or metal layer, it won't withstand the heat. Moreover, heating/cooling cycles destroy material slowly - and one of those layers could be marginal when manufactured, and pass the tests, and later get partially destroyed - and make the CPU prone to overheating.

Have you applied the 2.3.4 update?
This was supposedly a bug fixed in the 2.3.4 update...

Thanks for the replies.
Jack_R1 - sounds like a good theory, it's a shame theres no way (that i know) of checking whether the cpu is making errors like in prime95. I can stress test it but all I know is when it crashes. Presumably if the cpu is degraded it will be messing up alot.
Another theory I read about was that some phones where shipped with a fault in the main pcb that is supposed to reset the phone when it gets too hot as a protection measure.
GldRush98 - I will give it a go, I'm downloading the latest cm nightly which I presume is 2.3.4 - I had read that the reset fix was for nexus s phones though?
I've just treid undervolting the kernal, it might not fix it but it could be stable enough for most things. An undervolt of 75mv managed a stress test of 20mins which is a record without ice...
EDIT: StabilityTest does report errors. I just haven't been getting any, would this mean its not the cpu?

I think you're right, that fix was for the Nexus S.
Sorry bud

Same here.. It mainly starts after update the radio. If you check the last kmsg you'll see that it's the radio which crashed.
If I use my phone during charging, it resets all the time.
What I read is
* May be a hardware issue that HTC can fix (but my phone have more than one year so...)
* May be sim card issue. I'll change it tomorrow, will see.
I've never overclocked or overvolt my cell, mainly under clock to 960 and undervolt, so I reckon it's not our fault.

Its not a sim card issue for me.. Its been crashing without one in. Maybe worth disabling the radio and testing like that?
I just tried overvolting my cpu by 50mv and it seems rock solid. 1 hour 30 on stabilitytest without a crash and while charging. I'll keep testing and let you know. Might be worth a try if your willing to overvolt. Useful links here:
http://forum.xda-developers.com/showthread.php?t=1059423
http://www.tiamat-aosp.com/downloads/tiamat-n1/

so, if i understood this correctly, and to solve my random reboot problem..i have to flash tiamat-kernel, and then PSM +50 Nexus One file????
i am running cm7 rom my n1 is unlocked.

That's what I did, but I've no idea why so no guarantees. Another point is that it probably won't stop reboots entirely.. I put my phone on a hot water bottle and left it stress testing - it rebooted.
Should make it pretty stable for normal use if you don't live in a desert though.
Let me know how you get on.

i just installed the tiamat kernel i am thinking of trying it out before flashing the psm file

Sounds good. Maybe the fix was the tiamat kernal not the overvolt...
I've spent half the day fixing my phone after I somehow destroyed it in testing - left it on the hot water bottle stress testing too long. It decided to reset and then get stuck on the boot screen no matter what I tried to reflash.
Just got it working again now, running cm7 and tiamat (without ov) to test...

the tiamat kernel alone didn't help...i flashed the psm+50 file..i will report back...

Yeah, didn't work for me either, I've also tried insectRavens kernal to test and no difference there. +50 still seems to be radically more stable for me.
Something I did notice is that the default smartass governor used by tiamat slows my phone down, I've changed it to interactive using setcpu which seems to be about normal speed. Might be worth doing...

Sorry to say this but psm file didn't help me either

That's a shame. Ah well, maybe something particularly weird is going on with my phone. Seems to be fixed anyway.

I changed my SIM card, with no effect. I'm using the last redstar kernel and found it more stable but when charging. It's quite better, but not as good as I would.. sadly.

SLCD Nexus one 35°C then... reboot or freeze some ideas
Hi to everyone.... very interesting thread. I'm an owner of 2 nexus one, AMOLED and SLCD the first one is perfect the SLCD have overheating issue it was bought second hand on ebay it's a vodafone espana.
I've noticed that it's working perfect till its working temperature become 35.6°C i.e. 96.08°F. It can freeze (need to remove battery) or it reboot but freeze on colored cross logo. As soon as I shutdown it removing battery and try to power, it vibrates 7 seven times.
Searching on the web seven times vibrating is CPU working bad for bad temperature. Anyone has tried to disassemble nexus one and putting thermal paste on Snapdragon to reduce overheating and better heating dissipation?
For sure for better stability we need to overvolt but we need to eliminate overheating maybe also modifying plastic on the back of the down side of nexus one.
When I bought it, it was winter so anykind of issue now I need to shutdown if overheating remove battery and wait some minutes.
Stability test apk it's not a problem I can use it for one hour and half without issue using tiamat kernel vipermod plus +50mvolt with setcpu on demand with maximum of 422-466-499mhz for cpu frequency.
The real test is running Angry Birds Rio try playing with it (with full frequency 998mhz without tiamat kernel and vipermod I can play only some level maybe 10-15mins) with this kind of configuration I succeed playing for one hour and half before first reboot.
So Angry Birds is the real test (hoping that it has anykind of bugs ) maybe that physics calculation are written bad or are alots and cpu overheat.
P.S.
Anyone opened it putting thermal paste?
P.P.S.
Sorry for my english I'm from Italy hope I have been clear.
P.P.P.S.
Sorry for long post.
Best Regards
Tony

I finally send it back to HTC, for reparation. Costs me 55$, and 2weeks after, my nexy came back.
Since, all work. HTC changed all the main board. The nexus can go through 100°F without any reboot. So maybe you can do that, but it seems to be much more overheating :-/

Nexus 7 undervolting results - POST HERE

If you have undervolted your Nexus 7 or any other tegra 3 based device please post the results here so I can throw them into a Excel sheet for development.
Using advanced mathematics and complex formulas I will make a undervolted kernel that's stable for everyone. For that, I need ideally 30 results or more. Less is ok but more or equal is better.

In order to use "advanced mathematics" and "complex formulas".. You might want to provide a format for "the results" you want people to provide.. Without a stream of formatted data to input your "complex formulas" and "advanced mathematics" is impossible..

"Advanced mathematics" and "complex formulas" sounds like you are doing an infomercial.

My Galaxy Nexus is proof of undervolting being unstable using software while being stable with manually programming the voltages. So I am going to give this a good shot anyway.
My Galaxy Nexus uses SmartReflex to undervolt.
Look at this table I made:
https://docs.google.com/spreadsheet/ccc?key=0AuqacKmGLKJ6dEdJZG5QTmNtQnoyYk0zbm5IanluMHc#gid=1
You see the core or gpu was already crashing at 974mV, which was the reason why I stopped undervolting using the thread. But don't give up, I tried again using SmartReflex because I felt I should be able to get lower. And now I am at 911mV but I did not try to get lower yet.
I plan on undervolting by actually programming it. I don't know how you guys undervolt for the Nexus 7, since I am fairly new with this device.

Using that I can calculate which voltage to take that will work for 90% of us or 99% of us or maybe 100% ?
For that I need some results. The more the better.

The only voltage settings that will work for 100% of people are stock voltages.
you will run into endless problems if you release an undervolted kernel because what works for 75% of people won't work for the rest.
If you adjust voltages to include more people the people that can handle the lower voltages aren't getting the full savings their device can handle. Which defeats the point of releasing an undervolted kernel to save battery.
Undervolting should be up to the individual, just release with stock voltages and make a guide showing people how to undervolt.

^^ Truth
I've done a bit of pc overclocking over the years and we'd always seek out the best steppings to find cpu batches that would give a better clock speed for less volts. What would work on one person's cpu wouldn't work on another sometimes even within the same stepping. (My current machine is getting long in the tooth but it's running a 33% OC below stock volts and stable as a rock.)
When the N7 cpu's are tested the stock voltage is the point where 100% of them will run without issue. Certainly there are many, maybe even most N7's that will run undervolted but until you try it you just won't know. Undervolting needs to be done on a case by case basis.

I uv by 100mv on every step on Franco kernel and I've never had a sod or reboot. Maybe you could release different versions like light, medium and heavy to cater to different users that have sets than can uv more or less. To address all these people naysaying I say just go for it, don't let these people dishearten you from what you want to do. I'm sure there will always be users who are willing to try

sorry to break the fun lol
Opened a thread with undervolting settings in different situation. For now i think its the lowest possible

That's exactly the same as what I have done. 100mV right across the board, and I have also never had a reboot or any other negative effect from doing it. Just a bit more battery life.

I too UV 100mv across the board. Never had an issue. And I OC up to 1.6ghz.

Same here, no issues with 100mv UV on stock speeds. What would happen if we went too low, would it fail to boot at all or is there some safety mechanism that would allow us to boot into boot loader?

When either OCing or UVing, you should ALWAYS test out the changes prior to saving them as a persistent boot state. This way, if you set something too high/low and it proves to be unstable, if you restart the device it will revert back to normal.
In the event that you OC/UV too much, yes, you would see signs of instability. In some cases it could show up as soon as you applied to change, in other cases it could take a while to notice. For example, some games or other high processing powered activities could FC/crash. Or your tablet might freeze or reboot. But again, as long as you didn't save your changes as a boot setting, it will be fine once it reboots.
In the event that you did save it, and the settings were unstable for your device, you could boot up into recovery and then manually erase them from taking effect. Recovery doesn't use those settings, as it's technically a different OS. But that can be complicated a process for some. So test test test save. Or don't save and just apply them manually.
Two other points:
Yes, most (all?) devices do have safeguards to protect itself against permanent hardware damage from OC/UVing. If it gets too hot, they will often shut down to protect themselves.
And just because one device can handle being OC'd or UV'd to a certain level doesn't mean they all can. Very minor differences in each component can impact one devices ability from another. The manufacturers only test to see if they can handle the published speeds/etc., but in many cases they can go higher if set to. In others, not so much.

Thanks for that phonic. Given the range of ROMs and kernel's available and the improvements already built in, under volting may not help a lot but every bit helps. Eg this screen on time is pretty good.Close to six hours screen on time with iirc 35% battery remaining.
Paranoid android with motley kernel. I don't over clock the nexus 7 as its fast enough. In fact I under clocked it to 1000 MHz max before and it was still fast but the screenshots are at stock volts and speeds.

it's actually plain simple. If everyone posts results. I can make a kernel with voltages that work for 75% of all people or maybe for 95% of all Nexus 7 owners.
It's called mathematics. But to do that I need as much results as possible.
Easy to do if you know what you are doing, right ?

[GUIDE] [Hard mod] Nexus 5's throttling solved by adding thermal paste.

Try this at your own risk. Warranty is voided (obviously) if you do this mod.

Some important info first:
Phone info:
My Nexus 5 has a CPU binning of PVS 2 with -50mV undervolt for all clock speeds.
Running 4.4.2 stock rooted with latest stable Faux kernel.
Some shots of my Faux Clock settings (no signal in the pictures because i haven't put my SIM card in):

Don't even worry about that 85c limit that I set on picture 1. After this mod it wont even be close to 80c.

It showed 54c 1 second later but anyway its still cooler than any phone I had before.
I played until 20 minutes and there is still ZERO throttling. I haven't tried playing any longer though but at 20 minutes its just a little warm, not even close to hot.
Oh and the room temperature was 25c.
The Nexus 4 copper block mod http://forum.xda-developers.com/nexus-4/general/hardmod-nexus-4-investigating-thermal-t2144652 isn't ideal because of the smaller gap (1.5mm vs 0.5mm) so yeah.
WARNING: DON'T follow the way they applied the thermal paste on the N4 mod thread. IT IS WRONG because it will not be evenly spreaded.
Try to use good thermal paste's like the Noctua NT-H1, Arctic Cooling MX-2/MX-3/MX-4, Prolimatech PK-1/PK-2/PK-3, Tuniq TX-2, Gelid GC-Extreme and a few others that I can't recall.
Don't just pick any random paste because some are even WORSE than mayonnaise (yes, mayonnaise works but dont use it unless you want your phone to smell like rotten mayonnaise and I 'think' its electrically conductive).
DO NOT use electrically conductive thermal pastes like Indigo Xtreme & Coollaboratory Liquid Ultra/Pro as they are obviously not good for uses on the phone.
Also because the Indigo Xtreme & Coollaboratory Liquid Ultra/Pro WILL cause corrosion like this https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcSR8rn5Q92qYNmQmAbUJ4zzF5R5VzLsaZ_go1bxk8xfDHIDvWJZ
Now the guide:
Step 1: Take your phone apart using this guide http://www.ifixit.com/Teardown/Nexus+5+Teardown/19016
Step 2: Step 14 at above link shows that square box beside to the left of number 53.
Now clean the square box and the SKHynix RAM( as seen in Step 11 at above link) with and a microfibre cloth to prevent leaving lint as lint affects thermal transfer.
Pour some rubbing alcohol on the cloth an rub the red coloured number 3 and black 'tick' off as the ink might affect thermal transfer as well.
A tissue can be used too but just remember to blow/clean the lint off.
Step 3: (Read this before applying thermal paste http://www.tomshardware.com/reviews/cooling-air-pressure-heatsink,3058-9.html)
Now put thermal paste at the middle of the square box.
The paste has to cover the whole RAM (don't worry the CPU is just directly under it). Do not put too much or little as it isn't good.
Use the pea method like this http://core0.staticworld.net/images/article/2013/01/thermal-paste-thermal-100021574-orig.jpeg but you need to put much more because of the 0.5 mm gap between the RAM and the square box. Just make sure it fills the square box. Then put the RAM back.
It should look something like this when its done correctly (bottom right picture) https://www.dropbox.com/s/vci7uor6xlzt879/dsad.PNG
DO NOT let the paste overflow out of the box. To make sure how, just put the RAM back in place properly then take it out again.
If its too much/little then just add/remove some. To remove the additional paste, just use the microfibre cloth/tissue + rubbing alcohol to rub it away.
Now just put everything back and enjoy the phone that will probably never throttle while gaming Oh the thermal paste I used was Noctua NT-H1.
Well that's it. I hope my English is clear & good enough. Please leave a comment if there is anything more that I can add/remove/improve. Also leave a comment if you are unclear or have any questions regarding this.
Just hit thanks if this helped you

What's your PVS number?I don't have any before pics but i remember it was around 20-23k scores before the mod. Its not high but after doing this the phone only feels warm to the touch, not hot anymore. I've seen scores high as 38775 but no matter what I just can't get past 32k. Just fyi I live in Singapore.

I'm not sure, can never get it.
I don't under volt so I never bothered.
Yeah, I'm northern Alberta Canada.
Warm right now, unusually nice, means the bad stuff is coming with a vengeance.
Though prior to testing my core read
32c or so.. little lower then normal but not cold. When it's colder then a witch's tit here in February, I'll do a cold test then for yucks.

Mh, I'm still not sure that transfer heat to display is a good idea...

Display isn't hot either. That metal plate dissipates heat pretty well.

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.
