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.

How do you over clock?

Does anyone know how to over clock you're DI to say 1.2? Thanks for any help.

You first need to root your phone, then install a kernel that is compatible with whatever rom you are using, then you need to install an OCing app like SetCPU and adjust accordingly.

I'm rooted running the 2.2 RUU and I have set cpu. So do I just need a kernal? Which one?

i reccomend King Kernel bfs #4, best freaken kernel ever... its located... here

so when i install this kernal is it ok to just bump the cpu speed up to 1.2? are there any guides to do this?

A lot of factors come into play when you start overclocking, every rom will respond differently.
The first thing to do before anything is to do a complete nandroid back up.
When overclocking keep in mind that the more you overclock the more chances you have of making your system unstable.
I have experimented a quite a bit and I have found that the King Kernal #4 seems to work well for me and at 1.2 it seems to be pretty stable. Any higher than that and my phone will sometimes re-boot itself for no apparent reason.
Again, your rom may handle things different so experiment and see what works best for you.
And remember - Do a complete backup first!

I'm using the number 4 kernal and it only goes to 1.19 is this what you mean by 1.2? I have to keep mine at 1.1 ghz at 1.19 my di gets unstable

Ya that's as high as they can oc these chips. I can only get to 115 safely 119 just crashes. But the charging experience will be better than stock with the BFS #4.

Could you guys please tell me what your settings for setcpu are?
I want better battery life and a faster cpu but im noticing that my phone almost needs a wake up time when i come out of screen off.
Thanks so much

If you are experiencing slow wake up, try increasing the min cpu speed to something around 460. Better batt life and increased speed takes a lot of experimenting. Your OC speed might differ from others due to differences in the phones cpu. For example, I have never been able to oc to 1.19 without the phone freezing or rebooting. My phone can handle 1152 but 1113 is perfect. In my opinion, ROMs have something to due with best batt-speed combo. I am running Ruby 1.1.1 with a setcpu profile of Screen off=245 without any wake lag. Other ROMs I have tried had wake up lag at that speed profile.
My set up:
(ROM-ASOP) Ruby 1.1.1
King's #1 ASOP "I told you so"- only works with ASOP
With the ROM's "Gem" performance scaling setting off, I use setcpu to OC to 1113, min is 245. I have a profile set to SCREEN OFF = 384 max/245 min.
I haven't worried about battery life since I started using King's kernals (I've tried them all with every compatible ROM on xda). I have several posts elsewhere on XDA showing 12 plus hours on a single bump charge and heavy phone use. Good enough for me. Stock cpu speed plus Sense ROM seems slow to me now.....to each his own though.

I hope to get some help because i value the opinions of those on this forum. Currently i am running virtuous 2.7 with virt. kernal v2. I am rooted, s-off, 2.15.xx radio. I want performance without draining my battery. What are the best settings to use in setcpu?
I did try king's kernal #4, but it was rebooting. switched kernals this morning.

One other app I use in conjunction with SetCPU is MinFreeManager. This will readjust your free ram to a higher standard. But with SetCPU I have it at 1113/Ondemand with no custom profiles. One other thing I really don't set is the Set on Boot option. I don't know why but I do. So with SkyRaider Vanilla 3.0 RC3/ KingX Kernel #4/ and MinFreeManager my phone fly's. I can't say for certain what settings you need for your phone but 1113-1115 is preferred by "most" phones and keep the set on boot option off. I keep a Galaxy S live wallpaper running and pandora while browsing the web and no lag what-so-ever.
CyanogenMod 6.0.2 and KingX kernel #1 with the same setup runs almost as smooth.
Hope this helps you out.

[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
Sent from my T-Mobile G2 using XDA App

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.

[Q] AOSP, Kernals, and a Newbie.

I am fairly new to this scene.
I recently got an EVO and decided I hated Sense so I went looking for a stock ROM. Light and fast. I have tried Cyanogenmod7 and Salvage Mod. The thing is, the battery life I am getting with these ROMs is awful. Cyanogen I was losing 20% an hour with the screen off, the phone untouched. Salvage Mod, I am down to 85% in an hour and a half.
I have read about kernals and how they can help with battery life, speed up performance, etc. What are some that I should look into using and how do I go about applying them? Is there a failsafe if its a bad flash?
Also since Sense feels so slow and bloated (to me at least) what are some other good AOSP ROM's out there? That have a little more to it but is not loaded down with unnecessary tools I will never use.

Personally I run:
rom: CM7 Nightlies
Kernel: Tiamat 4.0.6 [3.3.7 is the GOD of battery life]
Mods: Viper mod, undervolted at 825mv floor and -100mv
CPU: Under clocked at 128 min and 537 max
Many people use my setup now and get great results, so I would recommend it to you.

Doesnt the nightly ROM tend to have more issues or do they run better than the stable builds?
What are the Mods? Viper, and then what does it mean undervolted at 825mv floor and -100mv?
Thanks for the help thus far!

mods = modification type tools
viperMOD is a mod put out by viperboy. it allows you to undervolt your kernel.
less voltage should translate to less battery consumption. take your time and read the post, it may look intimidating but it's rather simple. NOTE: if you lower your voltage too much your EVO will get stuck at the boot screen during the next reboot. do not fear...simply go into recovery and reflash your nightly this will reset your voltages. i'd suggest lowering the voltage in increments of 25 or 50 till it hangs then raise it by 25. run with that for a few days to see how it feels.
you may want to look at the Supercharger script (see signature), its not a battery saving mod, its more for memory management and system responsiveness. again, the OP looks intimidating but a reflash will reset your system. (ie: you will have to rerun both ViperMOD and SuperCharger each time you flash a new nightly)
nightly's may or may not be more stable than the RC. it all depends on what was added the day before. the easiest way to find a good nightly is to scan thru the nightly thread for a nightly that is a day or two old...if it causes issues folks will cry and moan in that thread...once you get a nightly that works well for you i'd suggest you stick with it until the link below indicates a new feature or fix that you need/want.
this page will list the EVO related changes included in the latest nightly
http://cm-nightlies.appspot.com/?device=supersonic
see signature links to viper, super and nightly threads.
have fun.

Salvage is awesome. Extremely light and plays well with V6 Scripts. Try them all out, give them a least a couple of days each.

How long does it take for the battery life to stabilize? Its looking like Salvage is averaging out to about 10% an hour, but I know I could do a whole lot better than that.
Any other Mods, kernals, or ROMs (especially AOSP) you guys would recommend?

After flashing a rom, charge the phone up to 100%, then go into recovery and wipe the battery stats; you'll see the change in roughly 2-3 days, as it has to 'settle' in.

note: there is a difference between a SBC and nonSBC kernel. this has to do with charging the battery. there are some folks that do like/trust SBC and others (myself included) that appreciate SBC. basically, SBC pretty much ensures that if you plug in your phone at night before you sleep when you take it off the charger in the morning you will have 100% battery to work with. Stock (or nonSBC kernels) will charge to 100% then stop charging and drain to 90% then charge to 100% rinse repeat. this means that when you take it off the charger you will have somewhere between 90-100% charge.
also, keep note of which applications are sync'ing and at what interval.
for example: do you need facebook to sync each hour? do you need weather to sync each hour? etc.

Also you might want to try SavagedZen RC4 and/or its kernels. They have built in HAVS (like Vipermod) and on the fly SBC (you can just uncheck and check it off)..

Jakister, do you have a link to that ROM? Reading up on it, it sounds awesome. I followed the main thread and the link to download it is dead
Nevermind, it must have just been down when I tried to DL it.

Try this one: http://mirror.savaged-zen.com/ forgot abt that dead link..happened to me when u try it from "mirror" instead from "download now" link. Works?

That one worked! I have flashed the Tiamat (sp?) kernal and the battery life was great for awhile but then it started to dive again. Also, the GPS could never grab ahold on the Cyogen mod. One of these days I will get it right!
Any other AOSP kernals you guys would recommend me look into? I also have the smartass governor on and have my CPU marked to go from 245-729. Do I need to make that lower? I figured 729 was a good compromise from 998
Any other AOSP Roms you guys would recommend?
I have looked at
Salvage Mod
Savaged Zen
Cyanogen Mod
Are there any other ones worth looking into? I think I need to figure out undervolting or find a better kernal

My Configuration
Savaged-Zen kernels have a new download server which can be found here: http://sz.munkibizness.com/ I personally use MIUI with a Savaged-Zen kernel along with viperMOD and Supercharger V6 for speed and simplicity.

How do Vipermod and Supercharger work exactly? You change the settings for those in the Terminal?

Yes, you change the settings for them in the Terminal. However, for vipermod, I use Terminal Emulator (available free in the Market) and for Supercharger V6 I use Script Manager (available free in Market also) and BusyBox Installer (in Market). For BusyBox Installer, make sure you have 1.18.2 or lower installed from within the app.

[Q] Cm7 vs Explod?

Hi guys, i was just wondering which rom is better with the evo or overall for battery life and gaming, "cm7" rom or the "explod" rom or now "decks"

Which rom is better would depend on what features you need in a rom.

what exactly makes it better? and if i used explod i would probably swap to go launcher.

why would you use Xplode to run Go Launcher? The first thing you'll notice with Xplode is that is basically a different launcher over CM7. Same as Deck's is Launcher 2 over CM7.
Just use CM7, then root explorer to replace ADW with Go launcher and you are in business

Also, you can you the timescape widget and the photos and videos widgets, which are cool, but can only run on that rom. You need the sony launcher. You can extract the sony launcher and run it in CM7, but you won't be able to use the timescape or photos/videos widget, as you'll be missing some sony framework. Also a different dialer. You can take the infinite view for contacts and run that on CM7 as well.

Check out my setup. I don't really use it for games but my current setup gives me exponentially better battery life than anything I was using before.
With other kernels I used I would have to underclock and switch my scaling profile in order to have my battery last more than a few hours. Now the battery lasts all day and I dont have to worry about losing performance by having to scale down my cpu at all. Amazing battery life while maintaining great performance. That's what I've found with this setup.

what cpu settings and governor do u use?

My understanding is that Decks is basically a stripped down CM7... Xplod is Decks with the Sony Experia launcher and widgets/apps added in (in place of the Decks launcher which is ADW if I remember right)... as well as some themed coloring that is different from Decks.
Performance wise, you shouldnt see too much difference, as they all started with CM7 and just had a little bit removed/added for personal prefrence.

this is a quote from decks: "Currently as i look at my phone, my battery stats have me at 31 hours and counting with 15% left. So battery life as you can tell was one of my main concerns. Everything works!!!" so the decks gingerbread rom was designed for more than just being like cm7

I am set to "On Demand" with my CPU set at 1.036ghz. Phone runs smoothly at this setting and my battery lasts forever. You can switch the scaling to performance, and up the clock speed a little, and you'll get even better performance. Albeit, your battery life will naturally go down, but it will still last longer than any other kernel combos I've tried.

with your clock speed set so low you don't really have to worry about battery life regardless of which scaling you use. Trying to game at 690 is going to be a pain in the ass as well. I don't really know anything about the Interactive/InteractiveX scalings. I've used Smartass before and I've been really pleased with the results of that scaling. I usually use Ondemand because that is the default setting that my phone goes to when I boot it up and I am too lazy to change it. When I do get around to changing it I will usually switch it to either Smartass or Performance depending on what I intend to do with the phone.
