Sticky UI w/ SetCPU & Kernels

Does anyone notice that SetCPU with kernels such as Hydra (1.15 uvoc) and King’s (#2 1.19) causes home screens and apps in drawer to scroll stickily?
I've ran both at max oc and it occurs. I know Hydra does not recommend setcpu. When I force stop setcpu with both kernels the problem goes away and the UI moves fast and slick.
Is there a way to have the benifits of SetCPU's Profiles while making the phone run fast and smoothly as when I force stop SetCPU???
Also are the battery drain problems that are plaguing people due to us using non-stock kernels... or us using oc kernels without SetCPU???

Personally, I've had nothing but disappointments with setcpu. Currently running kingklicks kernel #3 without setcpu. Plenty fast enough for me and better battery life than stock. I think the stock governor does a better job than setcpu.

Kingklick scaling is as good or better than creating profiles in setcpu. Using kingklick# 2 and# 3 as is has improved battery life greatly for me. I posted some" light use" battery life results in the kingklick thread and during the test period I was using setcpu to test the scaling abilities of kings kernal. Overclocking is overrated and setcpu doesn't play nice most of the time anyway. Use kingklick# 3 or# 2 as is and you should get good results. If not, im not much help. If you can't get kings kernal to be stable at least use an undervolted kernal.

Thatnks Sam. I agree. But I'm using #2 without setcpu. Its fast and smooth. Better Quad and Lin scores for me than #3 (currently trying) though but not significant. I'll see how it handles battle before I revert to #2
@Inc
I've been using king's #2 its performance is great. smooth without setcpu. What is the default speed of his kernels 2&3(oc1.19G) without setcpu?
Btw I'm running same phone configuration as your signature.

Setcpu is the issue

I have been bouncing back in and forth from rom to rom. Most are great. Warm 2.2, DamageControl, and Virus (currently running). The issue I'm having is no matter witch rom or kernal I run on my Evo froyo, every time I install Setcpu within a couple of hours my launcher (no matter witch one) stops working. I have gone into root to reinstall, install and uninstall and nothing works. All Rome are affected by what I can tell. I'm finding the problem to be with setcpu. I'm surprised if can't find much information on this. Does anyone have ideas?

Yea, setcpu can improve things but also causes issues elsewhere. I was using launcher pro for a while, and using that in conjunction with setcpu gave me nothing but poor battery life and terrible freezing. I have since then stopped using setcpu and my phone works fine. Besides the difference between 1ghz and 1.1-1.2 is negligible on the Evo unless your benchmarking imo

Stop putting your phone's minimum frequency at 128 or 245MHz. Also, tweak your launcher's memory settings properly.

I did all that already. I had my screen off set to 384mhz, im no novice, setcpu has great benefits but has some negatives also.
OP, try ziggys 10/26 kernel. It has scripts that handle oc'ing up to 1.13ghz using interactive governer WITHOUT using setcpu
sent from my DAMN Evo!!

I use SetCPU and Launcher Pro Plus and have used these 2 on every ROM I have used...which is a LOT!! My screen off is set to 245 and I OC to around 1228. I have NEVER had any issues on amy ROM. I dont know what is causing your issue but it isnt SetCPU and Launcher Pro....

[Q] Better battery life (Kernel Confusion)

Recently i've ventured into kernel threads wondering how i can get better battery life on my G2. I consider myself pretty well versed in roms but Kernels are a whole new animal for me.
I have read so many threads im becoming dizzy. If i have to flash a kernel for better battery, which one? I dont have demands for a faster phone. Most of the threads about kernels i have read are all about getting a faster clock. Im fine with the speed of my G2. I just want better battery.
Can some one provide me with some literature on the subject, point me in the right direction, or even better, answer some questions for a noob in this particular subject??
What Kernel to use?
Can i flash over CM 6.1 Stable?
Do i need to wipe before flash?
Any assistance will surely allow me to sleep better at night.
Thank you in advance.

I can tell you im running virtuous 7.2 i find pershoots kernel the best for battery.

If you want great battery life, don't use a sense rom. They're battery hogs as it is. Stay on CM 6.1 and flash pershoots latest kernel. Get setcpu and set a profile to 245/245 when the screen is off.
With these settings I get awesome battery life and I'm overclocked to 1497.

Oh ya i learned through trial and error to stay away from sense roms.
Can i ask you why you overclock? I dont find myself in any moments where i think the phone should be going faster.
I can flash pershoots over cm with no problems?
Can i get a link?
thanks for the response.

Well i lpike sense but only when its ocd sense too sluggish on stock g2 speeds. Also even with ocing and runing sense my bat last just about all day. It sometimes needs a shot a juice if im useing gps or playing a lot of games but thats it.

Decent battery life on my G2.
I'm running htc sence on mine with the pershoot kernal and cpu tuner.I have tweaked profiles and my battery life is better than b4.Example, i took it off the charger(ac) yesterday morning @ about 9:20am & today Thur, i checked the [email protected] 11:50am and my battery is only @ 40%.(1 day,3hrs & 31min's later)not bad.That's WITH moderate use.

So whats CPU Tuner? Do you have some suggestions for how to tweak the profile? Can i get a link to the pershoots thread? Is this the right thread? --> http://forum.xda-developers.com/showthread.php?t=847672
Do I have to wipe before flashing and then reinstall cm over it?
When I went into SetCPU, it always kinda confused me. That could be why I was never interested in overclocking.
I realize I have a lot of questions. Im just a careful and thorough person.

Simple.
@dangabob13...Don't worry about all the questions i'd want to b super carefull as well.First, cpu tuner is a free app in the market much like set cpu except u get more options as far as customizing your profiles.Second you can find the pershoot kernel right with in rom manager.Just go to the download rom section & its the 3rd one down.I didn't wipe and i haven't had any problems.The reason i switched to the pershoot kernel was because i was having problems waking up the screen with HTC sense and the kernel it came with.This fixed the issue for me.No need to b confused it's actually pretty simple.My profiles for cpu tuner are as follows:
Under the "Current" tab: i have the governor set to "conservative" i have the cpu o.c to 1094 MHZ.No need to go crazy over clocking i find this to b fast enough for now. The rest of my profiles:under the "profiles"tab,
Performance:Ondemand-Max:1094 Ghz,Min:768Mhz.
Good:Conservative-Max:1094Ghz,Min:768Mhz.
Normal:Conservative-Max:1094Ghz,Min:768Mhz.
Power save:Conservative-Max:1094mhz,Min:768Mhz.
Screen off:Conservative-Max:768Mhz,Min:768Mhz.
Extreme Power save:Conservative-Max:768Mhz,Min:768Mhz.
Keep in mind i also have wifi,blutooth,sync all disabled as well.I'm not saying this is guaranteed to work for you, I'm simply stating what works for me. Good luck i hope this helps.

Quick question....doesn't CM6.1 Stable have the pershoot kernel already? Also does the Pershoot kernel the one that goes to 1.8Mhz?
Not that I'm interested in going that high, but just wondering.
I OC for games mainly, but also to watch tv and movies, the extra umph really helps. My setup on SetCPU are:
Temp>40.2*C 368 / 245 Powersave Priority 100
Screen Off 245 / 245 Powersave Priority 90
Charging/full 1497 / 245 Interactive Priority 85
Battery<10% 268 / 245 Conservative Priority 80
Battery<30% 806 / 245 Conservative Priority 70
Hope this helps.

I dont have a conservative option under the Governor dropdown. is that important. Otherwise i duplicated your settings. Boasting 27 hours of up time and 40% left is bound to make me jealous ill test it out. Thanks again.

That's strange is your cpu tuner app up to date? I also wanted to mention that my screen brightness is set to 20%,heptic feed back is turned off and so is vibration. Along with a few other battery saving options you should see a difference in battery life.Obviously results will vary.

Ha its so funny. I have the same exact settings. i took a look around and turned off all that stuff. I keep my GPS on because it only uses battery when its being used. But i turn off wireless locations so that its not always trying to centralize my location.

Safe under and overclock for Desire Z?

What are the safe/stable clockspeeds for underclocking and overclocking my Desire Z? Also, what app do I use? Like, I don't mind paying for the app (as long as it's not too expensive)
Sent from my HTC Vision using XDA App

SetCPU can be used to overclock if you're rooted. Depending on the ROM and Kernel combination, overclocking to about 1.3ghz is usually safe. Some go up to 1.5ghz or even 1.8ghz, but are often quite unstable depending on other configurations you have in your ROM.
As far as underclocking goes, some custom kernels clock all the way down to 122mhz, I've been using a streamline5 kernel on CM7 (which offers 122mhz min) and haven't had any ill effects with this.

I have the Virtuous Sense ROM (with it's default kernel, although it does have other kernels which can give other cpu speeds), right now but might try out another ROM soon (maybe) do you know what's the min and safe max for this ROM?
Also, can I just set a particular clock speed (e.g. 500MHz) and it should be ok or is there any stability difference between say 500MHz and 505MHz? Just curious. I looked at SetCPU and it looks like a good one. Also, if the clock speed I set makes things go wrong, can I revert it or can I get stuck with it and need to do a wipe?

No, there's no need to set a particular clock speed. Just whatever works for you. I wouldn't recommend going under 800mhz, as the phone will really really bog down even with normal use.
I haven't used that particular ROM, but I'm assuming anywhere around 1.3ghz should be safe on the upper limit. Like I said before, anything above that might start to cause issues. You might also want to consider the battery life implications of severe overclocking.
You can change the clock speed any time you want. If you're having wakeup or heat or any other issues just go back to SetCPU and change the max clock speed again. You can also use profiles in SetCPU to change the clock speed when the phone is overheating, or when the screen is off, or when the battery gets to a certain %. There are tons of posts detailing how others have setup their SetCPU profiles.
One last note, don't forget to check the box for "Set on Boot" in SetCPU, this way your changes aren't undone on reboot.

Thank, I think I got everything I need to know in your last reply

I'm on CM7, with the CM7 kernel, and clocked in at 1.5GHz, and have no problems, and the rom is super fast. And I use SetCPU.

[Q] Best kernel for MIUI

I am currently using MIUI 1.7.29 Osimood with the Tiamat 1.04 kernel, and I am wondering what the best kernel is for battery life. I am also using the V6 supercharger ram script. I am running my CPU at 960mHz at the moment, using the smartass governer. I also undervolted using vipermod, 960MHz at 950mV.
My choice consists of the latest Pershoot, UmaroKernel 1.06 or Tiamat 1.04
What differences would I see between those kernels, are they noticeable for a regular user?

Sorry man, but wehre do you find the vipermod for desire z? http://vipermod.tiamat-dev.com/faq.php it's not compatibile with desire z/g2....

Uh...what's wrong with the kernel it comes with? Can OC to 1.5GHz stock ya know. Battery life is great with it too. People always want to flash something weather it be a radio or a kernel.

damn straight,
1) pershoot is a sense kernel? (i am proabably wrong but i have never tried this kernel)
2) umaro kernel i found had issues with wifi, high underclock freq (leading to poorer battery life), but fun if you have the time to tweak voltages and fast!
3) tiamat kernel i found had issues with sleep of death/random reboots on wakeup couldnt test it past that. (setcpu was set to screen off was: conservative 125min -345 max and would still crash)
if you are up for another kernel, i am now using this kernel (streamline5)
no voltage tweaking (pretweaked) but it has good batt, speedy and stable cant ask for much

Pershoot is actually for non-sense roms. The downfall people have with it is lack of governors. Some don't mind, some want variety. I've had great experiences with Pershoot's kernel and it's the baseline that all others are compared to (not to mention the foundation of almost ALL G2/DZ kernels).
Umaro's just needs to have voltage tweaks done manually but on the plus side - keeping the voltages normal (not UV) allows some people to reach higher OC speeds. It keeps the processor from bottoming out due to insufficient voltage which can easily happen when you UV. The main issue is with the Greased lightening governor - it's new and still a bit buggy.
Tiamat 1.0.4 is outstanding. I can sit all day at 2+ GHz (not literally, see: Chernobyl). I personally have an issue with the interactive governor but other than that it's my favorite kernel (Umaro may take that soon, once greased lightening is perfected).
Basically you just need to try out a few and see which you like. There is no 'best'. Most kernels will work with any ROM (Sense being the only exception).

Bumping a thread that is relevant to my interests.
It's about time for me to jump ship from an outdated CM ROM and try something new like a MIUI ROM.
With that said, I'd like to read more opinions & experiences from people using the various Kernels AND how the latest radio (the one released today) is working for them. I'm just trying to get the optimal experience here
Speaking of MIUI would anyone mind telling me some differences between OsiMood's ROM compared to the official MIUI-US ROM (or even DarkSpadez ROM)?
Thanks a ton guys!

I downloaded the official rom . . .then ignored it downloaded osimood and iv been using it since. Osimood is a lighter rom, which is always a good thing, unwanted languages etc are removed for a smaller faster rom. Also he preinstalls tweaks like an adblocker and extended settings mod.
Kernal wise iv been looking for the same info as you but couldn't find it. So I eneded up trying them all:
- Eugenes streamline5 is a nice kernal, preundervolted. Only probly is its not being updated so will become redundant.
-Tiamats kernal allows over clock to 2ghz and seems to support higher overclocks stably where other kernals can't. Except battery life has decreased with recent kernals
-Umarokernal this is the kernal iv come back to twice and am still on. It allows overclock to 1.9ghz and is kept updated by umaro. Performance per frequency seems as good if not better than most and osimoods miui runs smooth with this kernal on 800ghz with scarey governer (which saves battery) Another plus for me with this kernal is the scarey governer which for me definatly provides the best performance per battery ratio.

I'm currently running MIUI 1.8.5 with Eugene-Streamline 5 Kernel with the latest radio update Vision_Radio_12.57.60.25_26.10.04.12.
SetCPU with Governor ondemand provides me with better usage, power and responsive time then Smartass or Interactive.
OC to 1.2ghz
Battery life, about 30hrs with the regular 1350mah.

Its basically like an automatic setcpu (which can't be changed on the fly) built into the rom, its in virtuous unity roms

What sleep profiles are you guys usein. I seem to have rebooting issues with any kernel I try unless I go to a sense rom. I've tried the vipermod now to see how it goes

But how do you get the virtuos O/C daemon to work on MIUI?

You can download it threw rom manager. Even with that kernel I get reboot issues. I assume its cause system ram isn't being cleard fast enough. I'm gonna try 100mv increase to see if there's a difference.
