Releasing my kernel ver10 which has NO OVERCLOCKING but has Undervolting. I'm pretty happy with the speed of Tegra 2 and I think there are a few advantages in keeping our speed in stock. Advantages IMO are as follows
1. Better Battery life
2. Less heat
3. Stability (unless it is too undervolted)
Update 4/25/11
Releasing PimpMyGtab and My latest kernel ver 11 with no Overclocking, just stock Speeds..Underclock using PimpMyGtab
Here is the link on how to use PimpMyGtab
http://forum.xda-developers.com/showthread.php?t=1018411
** If you get a scaling_governor error upon starting PimpmyGtab. It means you need to set your governor by going to Terminal and typing echo powersave > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor or by installing CPU Master and choosing powersave in governor.
BIG THANKS TO CPASJUSTE for the app and kernel codes.
BTW, If you like my work, don't hesitate to buy me a beer
If you ike PimpMyGtab, make sure you buy PimpMyCPU (Source) from the market by Cpasjuste
Thanks.
Nice. I'm not a fan of overclocking, however undervolting DOES interest me. As soon as I get an opportunity, I may try this out.
Curious, what's the stock voltage?
OK, LMK how it goes.

Well I tried it out real quick, it works well (haven't verified battery life changes), but I had some questions:
Is there anyway to set the voltages explicitly? SetCPU didn't work with it (couldn't even change the freq or scaling governor).
I forgot your kernel doesn't support mounting the internal SD over USB. Is that something that will be fixed soon (assuming it's actually broken)?
I won't have my tab for a few weeks, sending it in for warranty replacement. So I won't be able to do further testing.
Thanks for the great work!
Hello clemsyn,
Try it out and battery life is soooooo gooood ... lot better than the OC 1.5GHZ one, of cause it run slower, but it's where i came to ask, if you could release one with the same voltage but for 1.2Ghz (which i guess it's stock speed)?
Many thanks for your hard work

OK here it is...this is basically stock voltage with OC to 1.2 ghz.
Thanks. Right now I'm tryingout the 700-900. Quadrant dropped from 2350 to 2150 going from ver9 to the UV.
I've been using the original kernel posted in this thread for a little while now. It has some strange slowdowns when the tablet first boots (from being powered off), but after that it runs great. Have not had any freezes, so it seems stable. Quadrant scores are ~ 2300.

While the quadrant is down a little, I can't really tell any difference in performance when using the tablet. If the battery life improves then I will stick with this one.
sorry if this has been answered before, but the undervolted
kernel still has cifs support?
(just to check, you need clockworkmod to install this, right?)

Seems like your tegra can't take the underclocked settings.
Well that sucks
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

To use overclocking and governers on sense roms, oc kernel and application like setcpu are must. Setcpu has governers too.

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

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.
So I was wondering about the truth behind the risks of frying your cpu through overclocking or the chip itself degrading faster over time, and if there are such risks do they apply to a simple 2.5 ghz overclocking ?
There isn't any risk like that, unless you are using extremely high voltage, or are at terribly hot place.
I have tested all the overclockable kernels, and haven't found a single one which is steady at 2.6 or 2.8 GHz. Only Faux's kernel at 2490 MHz is stable.
Don't be scared, there's no risk.
PS: I personally use Performance governor by the way, so the CPU is always at max frequency, against all advice I keep using that for past three years, never had a problem, and you can understand where I live the temperature reaches extremely high in summer, so...

If you want higher you should try out Ultimate Kernel. Although it is removed from XDA, you can still find it on some foreign language site. It's the highest and most stable OC kernel I have used (3.0GHz).

I think it comes with 2 apps for customization. You apply frequency on the first one and open the other and select apply changes. I'm not sure if it was this kernel or was it AEL. Lol. Anyways good luck. Maybe your ROM doesn't support a certain "stuff". I'm sorry but I really forgot about those terminologies. You can read up on the closed thread if you want. I'm sure you'll have a clue or on that link I gave you. *Google Translate ftw*
