SetCPU supports Tegra 2 (V2.2.0)

SetCPU master coolbho3000 has updated his app to include support for the Tegra 2. It's available at all the familiar places.
2.2.0 - Added an "In Call" profile. Improved the Set on Boot safemode function by including a flashable zip that toggles SetCPU's safemode. Press menu on the main tab for more details. Added autodetect support for all Tegra 2 fakeShmoo kernels (ie. G2x). Added a "Voltage" tab for undervolting the CPU on fakeShmoo kernels, some custom Galaxy S kernels, and some Nexus S kernels. This is a full-fledged interface for undervolting these devices, and includes backing up and restoring and a Set on Boot checkbox. Improved the way SetCPU initially requests root. Various miscellaneous bugfixes.

Undervolting in SetCPU, now that's fantastic. By far the best purchase I've made on the market.

Also has a cool feature that allows you to extract a zip file to your sdcard in case you've set it to 1.5/1.5 and your phone freaks out. You can just boot into recovery, flash the zip and it resets setcpu.

I must say, SetCPU 2.20 is quite amazing... worth every penny

Note to ppl who upgraded from existing setcpu...re-detect your cpu speeds from the main screen. Otherwise, voltage tab will force close on you.

What would you set "in-call" to?

I have 400/400 for screen off. I set in call to slightly higher at 400/500.
I'll need to test it tomorrow during calls and see if the screen wakes up quicker after a call ends.

For benching, I set it at 1500/1500 at 1300mV with no profile set for maximum power, and I'm getting much lower benchmarks in Smartbench 2011, than I was with pimpmycpu. Why do you think that would be?
pimpmycpu: 4400-4700
setcpu: 3700-4000

Wow very nice.

yes nice news ! Im happy to see old school

Great news. Just re-downloaded this and uninstalled pimp my cpu.

I did the same, but unfroze SETCPU and FROZE pimpmycpu.
In the transition, the battery got drained quite a bit over a few minutes, and heated up pretty fast when initially recharging. I had rebooted in between, but there may still have been some residual conflicts between the apps.
It froze at one point, but after a battery pull, it settled down. Overnight battery drain (with screen-off profile set pretty low) was only 4% over 8 hours. This is on EB 1.0.2 and faux stock kernel. Quadrent "only" around 4000, but everything works and this has apparently improved battery life.
A note on pimpmycpu - I thought scaling to min had stuck, but apparently not. Battery consumption was 12-15 % overnight compared to the above.

Thanks OP! I severely dislike pimpmycpu...

So am I the only one that is getting significantly lower smartbench 2011 results with this updated setcpu as opposed to pimpmycpu?

I have not seen that, although compared to Quadrent, I had not seen the very high scores that some had. I doubt SETCPU would impact you OC'd performance at max setting (although pimp had scheduler settings and SETCPU does not).

What are you overclocked to?

I guess you can consider this thread part survey and part for my knowledge so I know how far I can push this phone. I am at 1728MHz max with the interactive governor and cfq scheduler. Not sure if I'm going to do any undervolting, I can get through the day with about 40% remaining, and I have profiles set up for low battery and such. I am running CM10 with the 747 (I think that's what its called..) kernel and can push it to 2.1GHz. Is it stable at that high of a clockspeed? I can assume it turns your pretty Galaxy S3 into a convenient portable stove
By the way, sorry if this is the wrong section.

It really depends on your phone, I had mine at 2100 and it was stable. However it can very I had,a, Droid charge that ran the 1440 no problem, had it replaced and the new one could go above 1300 without hot boots. Some phones just hold up better

Stock. I've had it clocked to 1.9. But can't tell a difference with real day to day function except for worse battery drain and phone hotter.
Sent from a SYNERGIZED GalaxySIII

I have run the KT747 AOSP kernel at 2.1 ghz for a day or more and had no noticeable increase in heat, or decrease in battery life. (lulzactive or smartass v2 with either cfq or sio scheduler, no voltage changes in KT tweaker) I also saw very little or no gain in real world performance increase, and the benchmarking apps seemed to back that up. Typically run mine at 1.809 currently. Every phone cpu is different in terms of top speed, and voltage settings. Best thing to do, is to test them and see what works best for you. These 2 links, courtesy of the Ktoonez thread, provide some great info on kernel governor and scheduler settings. Given the number of options in KT Tweaker, these helped me a great deal in terms of making changes.

I've tried 1998MHz and as you said, it didn't yield much. I think I screwed something up, because now oc settings refuse to stick (resets itself to 1512) and short/long benches are not as great.

i think your question shouldn't be, "how to overclock", cause apparently you have already overclocked =="
your question should be "overclocking problems"
about your problem, i prefer you to set the performance down to 1.2 again, overclocking actually harms your hardware and is usually dangerous.
If you really want to overclock your phone, with 1.3GHZ, restore back to your stock kernel, and wipe cache, flash, wipe cache again, then reboot, i think this should help

1.2 is more than just fine for me on S2+.
Never had any lag or spike issue when multitasking.

sometimes the device freezes when overloaded with some operations but after overclocking it frozen more than before

I underclock it to 800mhz and it works fine, no lags. A typical daily usage for me: texts, whatsapp, emails (3 accounts synced), Neutron music player (which is said to require 1K mhz), browsing, instagram, occasional youtube, rss feeds.
But then again, I don't play games or watch videos/movies on it. Maybe this is what's causing lags and freezes for you?

I've tried for a day when I first flashed that kernel. Decided that the increased battery drain wasn't worth it.
What about apps, how many do you have? Also, widgets? Should check on them, could be the case of too many of them constantly running in the background.
Edit: Ah, just thought of this. What about the cpu governor and i/o scheduler that you're using

I dont really comprehend you here. So you flashed the kernel and that's it? If so, now you need an app like "setcpu", "no frills cpu control", etc.

I use Viber, whatsapp, Email, facebook 24x7 and they keep running in thd back ground. Along with that I also play all the heavy big games like Real Racing 3, Fifa 12, Modern Combat 4 etc. I run all those games from my Ext SD card. Never faced any lag issue. I believe the specs of this phone are awesome and you don't really need to over clock or under clock it. Never freezes for me.

Seriously mate? It's so simple. Just set your desired frequency with the app.
And choose the governor e.g smartassv2, ondemandx, interactivd, etc. But avoid powersave and conservative since you don't want lags and choppy performance. Here's a guide to cpu governors: http://forum.xda-developers.com/showthread.php?t=2017715

Thanks a lot brother may be i didn't explain it very well i have set the kernel and the frequency which is 1300 ondemand but apparently the device started to get slower than before overclocking that way i thought i might be ruining the phone by doing such a thing and it didn't get any better

FASTEST KTWEAKER SETTINGS? Post HERE

Hey! I just purchased two 2600mAh batteries for my S4 along with a Samsung Spare battery charger. Now, my phone is rooted and is running a custom Rom and kernel. I am using Ktoonsez KT-SGS4 TW ATT Edition. now what I'd like to know, is (since I'll have SO much battery power) what are the fastest possible Ktweaker settings that ARE STABLE AND DO NOT EXCEED 2.1Ghz? Let's turn this into a competition. Whoever can give me their best and awesome settings wins. C'mon guys, let's figure this out. I don't want conservative battery settings, I'd like some beastly processing settings that will help TouchWiz with the lag it contains. Please respond soon, you guys here at XDA are amazing.

And just how are you going to determine if I'm more beastly than you?

Balance is key my friend... the whole point of ktoonsez' kernel (well more like his govenor ktoonservative) is power with battery conservation. Even with 2x 2600 you need some or else you will kill both in a day. I have an anker 5600mah battery and it is possible to kill it in a day just from screen use.

Stock kernel settings (Ondemand at 1.8 GHz or something like that). Yes, you heard me, stock. Overclocking won't do much for you at all. The other thing you're changing is the governor, which simply chooses when to ramp up the clockspeed from resting state. Changing the governor isn't going to get you more FPS on something, or really even much faster load times, for the phone will ramp up to full speed when doing work or animations.
It's fun to tweak and play with this sorta stuff, but really, you're really just gonna get placebo in terms of speed, and if you try to save battery through undervolting, you'll either have rather unnecessary performance loss or instability. Also, overclocking runs the risk of burning up the phone, and possibly destroying it to where it never turns on again all for something you can barely notice.
You really wanna speed up your phone, make things load quicker, and overall make the experience faster? Get Greenify and hibernate any apps you don't actively use (you'd be amazed at how much some background apps like Facebook consume.) Go into your Developer Options and set the animation speeds to 0.5x (or even off). Use a custom launcher such as Action Launcher or Nova Launcher that will help you access your apps quicker. Get the AOSP web browser, which tends to be faster than the other browsers. Just don't go overclocking your phone acting like that 0.3 GHz of extra power usage and potential instability is making any more than a few fractions of a second in difference.

Safe undervolting? What's your settings?

What undervolting have people got set with what set up that's still safe and stable... How low can you actually go on the nexus 5?
For example... I'm currently...
Rom: stock with some apps removed
Runtime: ART
User style: just phone and Internet browsing, no games really ever
Kernel: linaro version of franco's
Kernel Settings: stock min and max frequency - 61 vibration amp setting.
Undervolt: - 50 across the board

All undervolting is safe. Just not necessarily stable. Varies for everyone (and evey CPU is different) so not sure this thread will help you.
