I'm curious on if anyone has ever tried to overclock a stock ROM. I know there is apps for it in the market, and custom is faster but I updated and like the way the set up is right now. Just wish my HTC Evo was faster.
Im no dev, but my undrstanding is overclocking is done in the kernel so imo yes you just need to root install clockwork mod(rom manager) in market and find a kernel supporting overclock, I would use this one http://forum.xda-developers.com/showthread.php?t=870760
this is for captivate only misread your post firs time.
htc is more hack friendly than samsuck and I have an overclocked mytouch so its possible you just need the right kernel
Any links to evo kernels?
Hi,
I am a new rooted user and have been following all MT4G threads here at XDA pretty closely. Can anyone help me know which kernels I can flash on the 03012011 Nightly(cm_glacier_full-11.zip ). I haven't ever flashed a kernel and I don't know what it does and how it helps.
I'll appreciate any info that you can give me.

Well you can use dumfuq's SmartCMKernel or Faux's CM7RC v1.3 kernels. ATM you might want to go with dumfuq's as its the most stable CM7 kernel other than default. You can find it in development section, once downloaded to SDCard just go in to Recovery and wipe cache, davlik and then Install zip from SDCard> Choose from SDCard> Select it wherever you put it and then flash it as you normally flash rom's. Then reboot and let it run for few min and let it do its thing.

Thanks for your help. Getting this kernel now. I heard about setcpu and Quadrant. Do I need those and how/what are they used for? what kind of difference would this kernel give me?
SetCPU - name explains it but if you don't know its controls clock frequency, so you can over/under clock and even set profiles.
Quadrant - benchmark app its just to brag how high score you got nothing special, don't let it get to your head it means nothing as the synthetic benchmark no way translate in to real world performance its just pissing contest lol
Keep in mind in CM7 you have built in mCPU performance controller to to handle clock frequency which you can access via Setting> CM Setting> Performance> CPU Setting.

You do relize you allready have a aftermarket kernel installed when you download any Rom here in the forums, right? Its ok to install different ones but FYI you dont need to in order to overclock.

Thats up to you as only you know what you use so you can better utilize the resource. I mean if you don't use anything no reason to OC it to 1.8ghz lol that way you will kill battery.

What are the differences between dumfuq's and faux's? Is there an advantage to one over the other? I've always been using faux's the whole time.
I keep going back to just using the stock CM 7 kernel clocked at 1.5 honestly I think it gives the best overall performance (on my phone at least) and honestly I had issues running over anything past 1.7 with any kernel but again that could just be my phone. I had it oc'ed at 1.7 for a while and now I have it clocked at 1.5 and notice I have less FC (not that I had many at 1.7 but def more apps would choke from time to time) This phone is pretty fast bone dry stock with no oc'ing but it runs beautiful at 1.5. I dont really notice much performance difference from 1.5 to 1.7 but I do notice a battery difference
Im rooted my desire Z yesterday to the gingerbread sense 3.0/3D rom.
im very happy that i have done it and my battery experience is either improved.
but my experience of the reaction time, smooth animation ect. were kindly bad
this is why i want to overclock my processor, but the rom included the new kernel 2.6.35.10 to be exactly. this kernel is not yet overclockable and i wanna know why.
- why make different kernels need different methods of overclocking
- why can it by bad if you overclock it to high.
- can i just flash another kernel to overclock my new gingerbread sense 3.0 rom.

if you overclock the processor of your device you can smoke your DZ
but if you do it with careful it is not bad for your device.
the kernel that you have its a stock kernel (factory kernel) and its not customized for to be over/underclocked... you should flash another kernel for to change CPU speeds...
nornally you can overclock your desire z (good machine mate ) 1.300mhz-1500mhz i not recommend to do overclock upper than 1500-1700... i had read some threads that some people was smoked his device (all with the proccessor QUALCOMM SNAPDRAGON 1ghz)another think its the freeze problem when you overclock your processor too much.. be careful!
and one important thing.. also its important if you do underclock.... don´t put it under 245mhz more or less because maybe your device don´t has sufficient power to exit of stanby mode
i recommend that ALWAYS do overclock with SETCPU.apk that its available free for XDA MEMBERS its the most safety mode
sorry for my english

Hi,
I'm new to rooting and flashing roms but I was able to to install the Sick Sense vx ROM and it is working very well. From the many hours of searching and reading I've done, I understand that I need to install an undervolt kernel as well as overclock kernel.
Any recommendations for...
undervolt kernel that plays nice with Sick Sense ROM?
and OC kernel?
I'm afraid of just flashing anything and bricking my phone. I read in one of the posts that someone thought he might have bricked his phone because of an OC kernel (Silver Needle or something like that) he had installed with Sick Sense vx ROM.
Thanks in advance...
You do not have to install another kernel. The one that is built for the ROM is usually the best. And you can't install 2 kernels...it is one or the other.

I used the Configurator that came with the ROM to try to enable undervolt but it gave me this error...
"your kernel does not support this feature"
But it sounds like others are able to enable to undervolt and unfortunately I don't know how they are able to...
Help?

Hello, I'm brand new to all of these roms and such, I've got a rooted 2.2.2 froyo g2x/lgP999. I am interested in getting a rom and a kernel. I am interested in getting ginger bread 2.3.3 and overclocking along with more battery life and a theme. Could I be linked to tutorials and suggested roms/kernels, and I have looked around but i really have no idea what im looking at so please don't say you've done nothing and are making us do all your work :\

Hi there,
If you don't have cwm recovery installed on your phone follow the instructions on this thread http://forum.xda-developers.com/showthread.php?t=1056847 to flash it.
Then pick one of the following 2.3.3 roms and flash it following the instructions provided on the thread:

There might be more 2.3.3 roms available in the development section, also you might wanna consider flashing a 2.3.7 rom, if so check out the development section and pick one, or try several roms and pick whichever one you like most. Devs are more active with 2.3.7 roms, so you'll find better support and more features.
As for the kernels, you can usually overclock your CPU with any custom rom (provided you get the appropriate app from the market if there are no OCing options built into the rom), but I haven't used a 2.3.3 rom in a long time so I'm not sure if OCing is available with the stock kernels they come with. If you do go with a 2.3.5 (or above, namely 2.3.7) rom then you can try either:
Morfic's kernel http://forum.xda-developers.com/showthread.php?t=1078049
or Faux's kernel http://forum.xda-developers.com/showthread.php?t=1073626
They're both excellent kernels, Trinity (Morfic's kernel) has a known issue with rebooting, the phone will freeze every now and then when you try to reboot so you'd have to do a battery pull.
Faux's kernel doesn't have that issue, but, for me at lease, when trying to reboot into recovery it does a normal reboot instead.
As you might already know, the G2X has a somewhat crappy battery life, most people can't get more than 24-30 hours of battery life with the stock battery, and from what I read most of the custom batteries aren't as good as advertised, so your best bet is to use an under volted kernel and try to find some battery tweaks in the forums.
There's way too many themes to list here but basically, for CM7 roms you can look for themes in the market, and for MIUI themes you can use their themes app to find something suitable.

A note on overclocking:
Please know that not all phones respond the same when overclocked. In other words, some phones can't handle the same overclock speed as other phones. And also note that overclocking sacrifices a bit of battery life to increase the performance, the extra juice has to come from somewhere. I suggest starting from the stock kernel of whichever rom you choose, see how your phone does on a stock, unmodded kernel. If you want a little more performance, then you can flash a custom one and slowly increase clock speed over time to see how your phone responds. If you want more battery life, then you should read up on UV (undervolting) settings in the custom kernel. The key is to try and find a nice combination of both so you can benefit great battery life and performance, but requires some tinkering and testing to get that right combination. Just something to note.
Phoenix Blood 1.7 with Faux123 048 kernel is the way to go. Do some reading on Google how to nvflash cwm and do a Android backup. Also titanium backup your applications and your golden.
Making bad decision's one at a time.

Thank you all for the fast response.
Now I have a question, are kernels used to acheive anything other than overclocking/undervolting? And are there any for 2.3.3 roms, if so which would you recommend?

Yes, your phone won't function without the kernel (obviously) and custom kernels are better than the stock one in that (in simple words) they improve performance and power consumption (kinda like drivers for computer parts).
I think the following would work for 2.3.3 roms, do a nandroid backup and try it, if it doesn't work just restore

I get better battery life on Eaglesblood 2.3.7 and Trinity ELP kernel (overclocked to 1.1GHz, normal is 1.0) than a stock based rom, like Weapon, will ever get. And on T15 kernel at 1.56 I can still get pretty damn good battery.

I run overclocked to 1.6 with a pretty aggressive undervolt. With the right profiles in setcpu I get better than stock battery and very very good performance.

Go to http://www.derkernel.com/ and look under current G2x kernels for 2.3.5 builds. There's ELPmax, T15max, and TD158. Don't flash any of these kernels if you're on a 2.3.3 rom though. Good luck

That is impressive but i would defiantly not recommend doing that if you are just starting... That can cause extreme instability...
If you want to undervolt start small and work your way up in increments making sure to not have the settings to "Apply on boot" that way if you get a crash (And you will until you find the sweet spot) you wont be stuck with your phone crashing over and over because the cpu/kernel is freaking out
And SetCPU is a great program for OC/UV for any rom
question i cant seem to quickly find about undervolting:
when undervolting in pimpmycpu (SetCPU crashes on me when I go to voltage settings for whatever reason) do you undervolt each setting? Like -50mv for 1.4GHz, -50mv for 1.2Ghz, -50mv for 1Ghz etc etc etc.. or just -50mv for the top (1.4Ghz) setting?
Oh, I'm on Faux's 048 kernel..

You only undervolt the clock speed you're using, you can do it for both min and max values, or just for one. But if you use multiple OC profiles, then you can UV every clock speed you're using.
Either way, UVing all clock speeds shouldn't cause any issues, but it wouldn't help much
