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...

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).

Setting the CPU to 400Mhz freezes?

I'm having an issue with my phone not being responsive if I set the CPU to 400Mhz. I first found this problem using Juice Defender then I uninstalled that and did it under SetCPU and it still did the same thing. The phone pretty much doesn't wake up after a while. I have to do a reboot in order for it to work again.

Don't get mad at me but IMHO overclocking and messing with a phones core features (what makes it run, processor, ram, etc.) is unsafe and can cause instability. And no I have no scientific research to back this up but it's just my two cents.

Lol I'm not mad. I don't really like to over clock. I just figured under clocking would work better. But nooooo lol

It does that under 800 mhz I forget why but I've read that in a couple places
Sent from my SGH-I997 using XDA App

underclocking that much is using less than 1/3rd of your true processor power.
your processor simply is not able to draw enough power to perform its background tasks - even when the phone is idle - when you underclock to such an extreme extent. therefore, it freezes trying to complete these processes.
if you're going to underclock, i'd say that 800 MHz is the lowest you can go if you are expecting your phone to do everything it is supposed to do. although it isn't going to save you THAT much battery life anyway, so you might as well just run it at the stock setting of 1200 MHz.

There's a known issue with setting CPU profiles to less than 800 MHz. A fix exists but some kernels don't have it.
Many of our Gingerbread kernels fix it, Infusion-GB is one of the few that hasn't pulled in the fix yet. (Although version 1.1 may have pulled it in, haven't checked github lately.)
None of the Froyo kernels have an explicit fix, but I'm not sure if the flaw even applies to our Froyo kernels as the clocking architecture is VERY different.

Hi, Rogers stock 2.3.3
It's using up 60% battery over night. Most likely I should turn off Wi-Fi.
I have underclocked to 100, 200, and 400 and it's stable --- minus the delay/lag at 100 and 200 . Sorry to seem like a troll.
I find that by default this phone either runs at 100mhz or 1200 on average, and 200 400 800 under 10%

Bumping from 100 to 1200 is classic ondemand governor behavior.
Also, some people never had problems even without netarchy's sleep patch running the CPU capped to 400 - but others have. I don't think anyone has had a problem with a patched kernel.

[Q] Have you managed to OC to 1460MHZ and keep stability?

I'm using AOSP+ ICS ROM with the latest Matr1x kernel. Whenever I try to OC to 1460 the phone freezes and I have to pull the battery, so I'm forced to run at a maximum of 1300MHz.
Also, on a related matter, is it good practice to use SetCPU with various profiles (battery<, temp>, screenoff, charging) for various frequencies? Or should I just use AOSP+ tweaks to chose a min and max frequency and let it be?
Thanks for taking the time to answer these.

If you are using deep idle you shouldn't underclock since it causes a race-to-idle condition. In other words your battery will drain faster. If you don't use deep idle, feel free to underclock when the screen is off or whatever you want.

Just an update, Using CNA 1.4.0 and Matr1x v17, I am stable oc'ed to 1460.
this is what I am running
1)800/1460
2)gov =Ondemand
3)Scheduler =Noop
4)all voltages to +30 (used the cna rom's voltage tweaker)
I tried ShadowGun: the Leftover.. and It was flying. Of course, make sure that have enough battery or that you have a charger ready. But finally it works, try this and let me know

I can run it for 10-20 min of usage then get a freeze. I never raised the voltages before though. It seems like its working for other people. And the actual developer of Matrix Kernel is telling you to ....
Nexus S (GSM i9020a)
AOKP (Build 25)
Eugene's Kernel (Speedy 7)
OC 800/100 (Lionheart)
Live OC (105)

It still amazes me how so many people that ask about overclocking have no frigging idea at all how cpus/gpus in general are binned etc.

I have a question. Why do you guys overclock that much? It might be snappy but battery life is just bad and it just doesn't worth it in my opinion.

Personally, I do it because I can. Seriously... I'm a geek, I love gadgets and tech and I like to tinker.
On the subject at hand, I'm still unable to OC to 1460 (ARM voltages +30, INT voltages +25) but at 1300 it runs fine, no issues whatsoever.

i can run 1460 stable all day. bigxie/matrix. just did +30 to all the voltages above 1000. deadline and lulzactive..

If you are a geek you would know about something as simple as binning chips. Do what a tech geek would do...look it up. Same thing the op should have done with his ?. Hell mathkid has a answer to his ? In the op of his kernel thread. Which is the kernel he is running

Voltage adjustment is not really necessary, unless you are increasing voltages for overclocking.

Well I tested it on my friends nexus s 4g and my epic 4g and with a lot of UVing. Lemme further explain.
Okay when you UV it just uses less amount of voltage on that frequency so in essence you save battery because not as much voltage is being used. Now however if you UV by a lot like -100mV and higher the phone will lagg a bit. If you overvolt your pushing more voltage to the phone which is more power being used.
I just tested my phone freqs. Used were 100,200,400,600,800,1000 And all were UVed by -100mV and playing games and using lower freqs it will lagg. When I didn't UV at all it never lagged.
Not to mention BTW I was @ 88% before and it only took me 2 mins to post this and now I'm at 86% with no UV at all. And last post before this I took me same time with UVed I went from 95% to 95% lol.

Well I can say every phone is a tad bit diff. But for whatever reason no matter who's phone when I UV if the phone handles it it. It saves me battery I want you to test this and see.
Run whatever scheduler and say performance run 100 MHz by -200mV like and 200 Mhz by -150mV and so forth. Play GtA 3 and watch when UVed it laggs and when Not it laggs stillbut not as bad. I mean hell even 1.5GHz no UV I still lagg haha

SetCPU

I know that if you OC/UV incorrectly, it can cause stability issues. But I was wondering does it cause any damage to the phones hardware like battery, etc? And like how can you tell when SETCPU is causing problems?
Sent from my LG-P999 using xda premium

Well if you OC to high numbers your just stressing the cpu more.Knowing when you have issues is simple getting random reboots,phone getting too hot etcc.
It differs for every phone but undervolting -25 for each voltages works well.
Personally I really don't see the point overclocking to high levels like 1.4 ghz etc,Is up to individual I guess.

Yeah I have been wondering what's the point of OC to 1.4? Does it make that big of a difference in the 4g speed? And cpu speed?
Sent from my LG-P999 using xda premium

Honestly, there really is no point other than for benchmarks. I, like mt3g, actually underclock the phone to something like 750-760mhz; it runs beautifully smooth.
Other than that, if you game a lot and want to maximize FPS, then overclocking would do that for you.
Doesn't have anything to do with 4g speed afaik. That's entirely reception.

Yeah 4g is about reception and tmobile simply.
I mean I had single core devices like MT4g ,SGS 4g for the most part on a day to day basis transitions to transitions theres not much diffirence in terms of speed. Now for FPS and a few other games you need that dual core.Point is there"s no need to OC a dual core phone!

I have had mine OC'd to 1.1 ghz with some undervolts. It is very stable , 10-12 hr battery with medium to heavy use , and ofcourse fast. Took a while to find the best settings.

When I have SetCPU set to 1015 megahertz, that's the same as stock voltage, isn't it?

Changes you might see are battery life but not that much unless you so how mess with voltage. Like other have said you know it effecting stability when its overheating, shutting down randomly, exiting program randomly.
