[Q] Cyanogenmod 10 with Trinity 7 CPU overclocking - Nexus 7 Q&A, Help & Troubleshooting

So I'm kind of new to messing around with tablets but learning a few things. On my Nexus 7 I decided to put Cyanogenmod 10 on it so I could customize a few things. I then decided I wanted to overclock the max CPU frequency past 1300 MHz so I installed Trinity 7 kernel. Now I'm able to run it at 1700 MHz which runs a few apps much faster but after exiting out of the apps and going back to check on the max CPU frequency and it's set back down to 1300 MHz.
Does anyone have an idea what could be causing this? So far there's only one app I'm overclocking for so it's not a big issue but it would still be nice to figure out the issue.
Thanks

I down loaded too. I just changed the governer to performance and it stays on 1600 etc on set cpu

There might be an option for "set at boot." Try that.

That's not the solution. The performance governor keeps the cpu speed at max frequency at all times (even when screen is off). That will eat up your battery quick.

Thanks that seemed to have fixed it though I figured out you have to turn that on THEN pick the max CPU frequency. Doing it the other way around won't change anything, I think that's what I tried before.
Also mccolvinj I'd personally leave it on interactive so it will just use the max CPU when needed or at least that's what I got out of the descriptions of governors I looked up.
EDIT: Nevermind...that only temporarily fixed it, it went back to 1300 after a bit. Maybe I installed Trinity 7 wrong?

I think so since it's rooted, is there a way I can check or give it permissions?

you need the powerHAL "fix". your rom should include it, but i guess it doesnt. search the n7 forums for a flashable. or, the trinity kernel toolbox app includes the "fix" just in case your rom doesnt.

Check in the superuser app
Sent from my Rezound using xda app-developers app

kernels arent rooted, your roms are. you can flash a custom kernel on a rom without root. the only difference is that you wouldnt be able to control the cpu with ant cpu control apps, the apps need root.
ive posted the solution already. either find the flashable powerHAL fix or use the trinity kernel toolbox to control the kernel. tkt includes the powerHAL fix.

Under/Overclocking the Rooted Hero

Anyone tried it yet?
I'm browsing through the market apps under the search "root" and I'm seeing a couple overclocking apps. Particularly SetCPU and Overclock widget, the latter being a free app.
I'm kinda nervous about what clock speeds the Hero will tolerate. I don't want to risk bricking my phone!
The "free" app on market won't let me clock it past 528. I don't think there is an app per se that can jack it over that speed.

Yup i used another app to set it to 575, but the highest it went was 528. actually it was only like 526.XX
The Overclock Widget didn't work at all.
The widgets on the market are bound by the min and max clock values compiled into the kernel I believe.
There's maybe a kernel interface in /sys/ somewhere where you can echo in a clockspeed, but I haven't found it yet.
As for the max it would support? The G1/2 were throttled ~350 if I remember, but it was on this processor, which supported 528mhz, allowing for crazy clock speeds at the expense of battery life.
No idea if this proc will really support anything much over that, you'd be getting into 'true' overclocking territory there, and the potential for damage to the phone would be significantly increased.
[edit]
The usual /sys/devices/system/cpu/cpu0/cpufreq/ directory exists, but it doesn't look like you can just set a speed there in the 'normal' linux fasion:
Code:
# echo 540000 > cpuinfo_max_freq
cannot create cpuinfo_max_freq: permission denied

I'm at work as well and kinda need my phone for stuff or else I'd be tinkering away.... but when I get home I'll see if it's working or not...
*NOTE* i r dumb in the ways of overclocking so I won't be able to fix code to get this to work
It seems to work when i put it on the slowest my phone goes alot slower and when i set it higher it goes faster but it will also decrease battery performance

Very cool! I wonder what a good balance between more power with not too much more battery drain would be.
Can't get it to work
Can't get it to work
When I start the app I can see the two bars:
Min is 528 and
Max is 528 as well
I adjust the Minbar to 128 and click
"Set to it!"
Display notification:
"Set new clock successfull"
When I start the app again: No change at all, still
Min is 528 and
Max is 528
Display icon always shows:
527
Any advise?

Is their any way to get the overclock to 768 while running the stock hero?
I have mine rooted of course, but I'm limited to 528mhz with setcpu.
Is their anyway to flash something so that max can be lifted?
Thanks.

Here princess.
Also..
Both include setcpu.txt for Setcpu OC app.. Select "custom" at the very bottom for device. Do not select hero. Or you can select "Auto Detect" at the top, this does not need the setcpu.txt.
*damage537.zip* 537mhz is the default.. scalable to 768 if you use an OC'ing app
*damage768.zip* 768mhz default clock speed -read below
*damage710.zip* 710mhz default clock speed -read below
Both can be scaled from 19.2 to 768mhz..
DAMAGE710--The damage710 will default 710mhz, you must use an OC app to scale it to 768. Use damage710 if your phone can not boot the 768mhz. And dont scale any higher then 710mhz or your phone might reboot.
DAMAGE768--If your phone can boot the 768mhz then either download will work. But if you dont want to use an OC'ing app then the damage768 will scale to 768mhz.

well just incase it wasnt gone over , in order to overclock you need a kernel that has been modified to do this. there are several on this forum for the 2.1.
On a side not there is the god kernel that can both be run with or with out the overclocking apps.
I actually beleive the best performance is from the 710 kernel with out an overclocking widget. the widgets seem to introduce lag till they set the clock this is a major annoyance when the phone is woke for an incomming call.
Do a nand backup and test for your self.
kernels located here

Thanks for the info guys.
I flashed the 710 one ontop of my stock 2.1 rom.
Now I'm looking at the green HTC logo with white background. It hasen't changed for 10 minutes. I think its stuck. Should I be worried?

[Q] Is it possible to overclock above 768mhz?

just curious really as my phone never gets warm or anything running at 768mhz the battery life is also pretty good.
hey,
i don´t think so, because in the worst case your phone will take damage. But this ~770 mhz are about 250 more then before. Im happy with this xDDD
that is true haha, i just dont see it doing much harm if the phone will run stable higher at the same voltage or the tiniest bit higher
No, that's the limit of the MSM7225. (Achieved by adjusting the PLL to its max, any higher will overrun the limits of the chip, and cause it to most likely fail)
i would like to know, if its very bad for the phone, if you let it permanently run with full speed. Ok, if it will get very hot.. thats clear, but is it bad if you have the 77mhz and it is for example in silent mode, or when you listen to some music. Should you ever take some possible speed away, if its not need? (thx)
The hardware life will probably be reduced. By how much, it cannot be said definitively, but, I am pretty sure that by the time the hardware fails because of overclocking, the phone will have been retired long back.
What you are requesting (Dynamically changing speed) is exactly what Speed Governors (Performance, Internative, OnDemand etc) do. If you are on CM7, use Smartass Governor, because it's the "smartest". If not, then use Interactive governor.
i use ginger yoshi... and sometimes it sais that the sd was removed. Could overclock be a reason for this?
I dont think so. I got the same issue once, and formatting the SDCard fixed it.
ok i will try it thanks

SetCPU no longer underclocking at low usage?

I have moved from CM7 to Hombase 5.4, and found that setcpu no longer seems to do anything. on CM7 it worked as i had hoped, underclocking the phone when i was doing low intensity stuff like texting, and pushing it up to full power for videos etc. now it does nothing but tell me core temps, which are always high as its always running at 1Ghz.
Can anyone explain how to get it back to underclocking?
Many Thanks
Try a different kernel.

This is a known issue with the OC faux kernel. I was running into the same problem with his enhanced stock kernel after using webtop. After reflashing the enhanced stock 0.2.0 it would still get stuck at max 1Ghz after using webtop, but a reboot would get the underclocking working again.
I only tried the webtop hack to see if I could get it working. I haven't gone back into it at all so I don't know if this is something that will reoccur. Although I will say that with my day to day use I have not run into any clocking issues since.
Thanks, is there a page somewhere which details which kernels do what and which would work with my rom?

This is the page for faux's kernels. As far as details, start reading and searching through that thread as well as the threads for any ROMS you are using. 99% of the time people will either have the same problem (and possible fix), the other 1% of the time they will identify a bug (i.e. maxed out CPU).
Keep in mind faux does have different kernels for Froyo, GB, and CM7.
For some reason even if I move the slider from 1300my to 1000, when I touch the screen with at least 3 fingers for a few seconds it pegs out at 1300. I read our cpu's are daisy chained so to speak
so the 2nd core kicks in when needed. I tried cpu tuner and it gives the option to powersave and only use one core or if you choose performance it will allow Both cores. Just might be setcpu isn't designed fully for our dual core setup.
thanks for the link to kernels, but i cant find one for HomBase, or a Kernel only download on the homebase thread. i have the Version2, which has some blur, but only the 1.0Ghz clock kernel. where could i get the 1.3GHz download by itself, to see if that might help, as its the one CM7 had iirc
Thanks

Get the 1.3 from the faux thread that I linked to. They're in the very first post...
CM7 is the only ROM that has its own custom faux kernel. For all other ROMS just match the kernel to the build the ROM is based off of (Froyo or GB). If you're using V.2 of Homebase then use the GB one.
Update: Also, there are other kernels out there. I was only using faux's as an example since you were using CM7 and Homebase.
thanks, ive now got the 1.3Ghz kernel installed successfuly, but it still seems like setcpu will not underclock. i dont know if its normal, but the "Scaling" option is greyed out, and i cant get access to the Advanced tab. is there something im doing wrong in setcpu itself?
thanks again

Lack of underclocking is a known issue with the latest OC kernel. I'm unclear whether it's actually a bug with the kernel or with setCPU not supporting dual core devices. But yeah, there's a problem with it right now. I'm on the stock enhanced, and other than the webtop issue I mentioned above, it works fine.
Scaling/advanced are not available, this is something that is determined by the kernel you are using not the app.
ok so if i understand you right i would be best off using the stock enhanced kernel (for now), as it will underclock fine?

It's working perfectly for me, except after webtop use (which I don't normally use).
I'm still having the same issues regardless of weather I choose power save or performance it will not underclock, and those are the only governors I get the option of :s

Trinity Kernel...1400mhz max?

I recently flashed the newest Trinity Kernel on my Nexus 7. I still have the stock ROM. I tried to tweak the CPU settings with ROM Toolbox and the most I can overclock is 1400mhz. Why can't I overclock to 1600? Is it because of the stock ROM? I'm looking into Glazed Jelly Bean as a custom ROM but I'm not sure I want or need to use a custom ROM at this point.
Any suggestions?
Because he dropped the Max. You probably flashed A111 correct? That's a TSVZ meaning it is slightly over clocked and undervolted kernel meant for battery not for performance.

Nice, ill have to look into rooting sometime soon.
Ok, I got the a96 and I've flashed it...
Is there a detailed changelog for each version? The a111 said it was a 1600mhz kernel so I don't understand why it was dropped down to 1400. That's where my confusion was.
I did notice some increase in speed at 1400. I was having some stuttering issues with Dead Trigger and Minecraft PE, and they were less with the 1400. I've got it running at 1600 now but I don't know what it will do to the battery or how well it will perform. I'll find out later. I've run through the battery pretty quickly today, but I was tinkering with it A LOT so it's not accurate.
What kind of tweaks could I do using Rom Toolbox that would help me maximize my battery while overclocking to 1.6?
Dont over clock.. i dont even see a need to. I use the ondemand gov which stutters a little but using interactive clears that up. Also using the CFQ IO as it is the stock IO used. Its stock so its gotta be good . Also you should turn F-Sync off that helps quite a bit. Also you could toggle auto hotplug and make it only run two cores while gaming and then turn it back on when finished so that way it will hotplug cores as it sees necessary. You could also up the voltages a little bit, some CPU's dont like the lower voltage and that will cause stuttering and glitching just up them by 25mV and see if it clears if not try another 25mV.
I will try those things, but I really want to play with overclocking and learn what happens. This is my first Android device so I'm experimenting and playing around.
But I have one more question...I've overclocked to 1.5...I found 1.6 to be the same as 1.5. But it seems that after an hour or so, it resets to 1.3. in ROMToolbox. Why is this?
Don't use rom toolbox. Use the Trinity app. It sticks just fine for me. Besides you support the dev to make better kernels.

youre not the first
Overclocking past 1.4 Ghz doesn't result in any major usability improvements. I've gone up to 1.7 Ghz and the only thing it does is make my tablet really warm and unstable. All you really need for improving system performance is I/O tweaks to speed up app and page loading, and a little bit of GPU overclocking to help with the transitional effects.
and, to be honest, depending which trinity kernel im using, im using either 1100 or 1150mhz mostly. on a111 im using 1100mhz and on a96 i used 1150mhz. with those speeds everything is still fast but a bit better on battery
Overclocking
If you want a little more information about the the overclocking if you havent already you might want to check out http://forum.xda-developers.com/showthread.php?t=1788759 its the official thread of the trinity kernel for grouper.

how to change CPU speed or what do you use?

after i load any one of the many kernels on my Nexus 7, I use ROM control and can see its at 1300 but can slide all the way to 1800. once i do this and even mark set on boot and then exit... the speed always goes back to 1300. in all my benchmarks it shows 1300 was the speed but if i go back into rom tool back it shows 1300 as the setting as if i never changed it however i can still slide to 1800.
even tried a reboot and still no luck.
what am i supposed to use?

it was called
1.8ghz650GPUNopix.zip
and now i just installed
grouper-faux123-kernel-v010ultimate.zip which now defaults to 1500 with the slider allowing ability to go up to 1700 but always goes back to 1700.
whats the point of giving the ability to change CPU speed in ROm tool box if it doesnt want to remember what you set it to. so annoying.
its not the kernels fault. your rom is "broken", you need the powerhal fix, it should be in your rom but it isnt. theres a flashable powerhal fix floating around the forums. also, some cpu control apps include it, like the Trinity Kernel Toolbox.
When this happens to me with Antutu CPU Master I just bring the minimum down to 51 and then drag it back to whatever I want. I'm also just running the CM10 nightlies.
