[KERNEL] Clemsyn Version 11 PimpMyGtab Underclocking control

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.

stock - 750mv - 1000mv

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.

Thanks clemsys for this OC, but got FC every time i run Quadrant ... anyway back to version 10 uv for now

Hmmm, for some reason my pad won't run any of your Ginger undervolted offerings (can't get past my splash screen). But I'm very happy with Ginger9... Thanks!

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?)

Yes it does and cwm is required to install

thanks soo much for this. I've been wanting to undervolt but the overclocking for me was a deal breaker. 1ghz is fast enough for any android app imo. Gonna try this soon!!!!!

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

Well that sucks

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.

Mildly on topic question ... do you notice any imporvments with overclocking? My first experience with overclocking as on my Hero, and then Galaxy S1, but this N7 just feels so fast i cant see overclocking making it any smoother? lol
thanks

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

Best Kernel for 4.2

Hey everyone, I have been on the hunt for the last few days for the best Kernel for my N7, in regards to performance. Earlier today someone turned me onto M-Kernel. I must say, it is very impressive. It has a built in 1.9 GHz overclock, that I was able to set via no-frills. I am running Clean ROM.
This is a multi-purpose post. First off, I wanted to let everyone know about my experience because I had a little trouble figuring out the best combo. The second reason is I would like to know if anyone knows of any other ROM/Kernel combos to get the highest quadrant score possible.
I have a co-worker who has a Galaxy SIII, and we have a friendly rivalry. I would really like to blow his phone away with my Nexus.
Thanks!

Check the link in my sig for my guide to the 'best' kernels. I don't think there is a lot of difference between roms in terms of benchmarks results.

PIE control

Most important one.. Stability. Needs to be stable, and have a few minor tweaks, it all depends on how the stock kernel is though.. HTC Stock kernels tend to be pretty sweet anyway and just need a few features added IMO.

Have been told that the CPU is way under clocked @2.3,GHz and could handle 3.00ghz easy! Note that this is a rumour, but if true wow!
Really looking forward to it now!

Um everything you listed is stuff that is the norm for custom kernels. Wonder if well see Franco or faux or flar here...im still really on the fence.

At the price probably only if the device is donated. I'm sure the size is off putting for them.

USB-OTG and USB-Audio support would be stellar (if not included as standard)
:good:

I would love to see the GPU and CPU overclocking as well as over/under volt for both for maximum tuning capability. The other things I would like to see though are RAM and bus overclocking access since with so many GPU cores if we get to overclocking we may need some more in those areas too so we can take full advantage of the higher core MHz

But i do have my doubts
because what happened to the shield tablet

Overclocking snapdragon 800.

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...

That's actually comforting I too am using fauxclock and I live in Egypt so the temperature gets pretty high here, but I'm constantly monitoring the cpu's temperature so I will give the 2.5 ghz overclock a try for a while and see how it goes.

Yeah do that. Just to see if the OC is stable run that damn Antutu benchmark. If the device doesn't reboot/stuck then OC is stable
Best of luck.

Ha ha. Good. That's on Faux right? I got almost same score (44.7k) when I was checking.
Now if you want more then flash one of those 2.6 or 2.8 GHz kernels, and do the test, and message me if Antutu finishes the benchmark even once

will do.

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).

Thanks a lot for the link mate. Downloaded and flashed v73, but I can't get it past the stock clock rate of 2265 MHz! I mean I have tried to set higher frequency than that in S Tweaks, even downloaded Trickstar, SetCPU, but the it'd just stuck at 2265 MHz! I can go lower than 2265 but not higher! Weird!

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*
