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.

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
So I recently rooted my Galaxy Nexus and other than using WidgetLocker I haven't done anything to my phone to take advantage of my root and SU privileges.
This is my first phone that I have done this too so this is all a major learning curve which brings me to my question(s):
(1) Can the phones memory be over locked?
[If yes....] What are the factory Memory Times and what is a safe level to overclock them to - and How?
(2) What is the factory setting for the processor and what is a safe and efficient overclocked setting?
Is the Highest (but again safe and efficient) level a noticeable change?
(3) Overclocking the GPU can reach a maximum setting of 512Mhz (correct?)
What is the default setting for the GPU and is overclocking the GPU to the highest (but "safest" & efficient) level noticeable and worth the trouble?
(4) How do I overclock my phone?
I know that (probably) a kernel replacement is going to be the answer to this question but I was wondering if maybe there is a script I could run in recovery console or terminal, whatever...instead of replacing the entire kernel.
If the kernel is the only way, does this effect future ICS system updates?
What is the best (most stable, most features, best for overclocking) kernel for ICS/GalaxyNexus? - I dont know poop about kernels.
(4a) with the kernel loaded, what apps do I need to snatch from the market to actually overclock my Galaxy Nexus? Try to recommend free ones please =P
(5) Since I am replacing the Kernel, should I dive in 100% and flash a ROM too?
Yes?: what is the best (very very stable, fast, efficient, tweakable) ROM out there for GNexus?
do roms do anything to assist in the overclocking process?
The only reason I would consider a ROM too is because I want Wifi/USB Tethering, Facebook contact syncing, and a few other things.. but only if there are overclocking tools too!
Does flashing a ROM eliminate myself from ICS updates(pretty sure the answer is yes)??
(6) I am currently on a stock kernel and "rom" (if u couldn't tell...) but I am rooted and using Launcher Pro (free version) and I am happy with it but out of the other launchers which is the best (fastest, easy to use, customisable)?
If I flash a custom ROM will a custom launcher be necessary or do they cone with tweaked launchers?
I had other questions but I can't think of it right now, I'll update the OP and thread if I think of anymore. Thank you so much community members for taking time to answer these questions!!!

1200 MHz is stock, 1350-1400 MHz is the highest you can get at the moment, as stability is an issue.

307MHz is stock (underclocked), 387MHz I believe is it's nominal speed, and is billed as 'overclocked' here on XDA.

You need to flash a kernel using CWM Recovery. The kernel will be rewritten every time you flash a new ROM with that ROMs kernel, if you like a specific kernel you can reflash after installing a ROM, I use Franco Kernel which is by far the most popular. Once you flash a custom ROM you won't bother with ICS system updates, custom are bleeding edge with custom tweaks and months and months earlier than OTA releases.

SetCPU is by far the best, don't be a cheapskate shell out the $2 for it. AOKP ROM has one built in, but I still use SetCPU.

Flashing a custom ROM will stop you being able to recieve OTA's, yes. But like I said earlier, they are ****. Custom ROMs are far, far better, so just keep up to date with your ROMs releases and you will always have a ROM with more features that stock OTAs. Most ROMS come with overclocked kernels, most have optimized kernels also, AOKP even has a built in overclocking program in the settings menu, which might appeal to you.

I don't know about other ROMs but AOKP comes with a custom launcher called Nova Launcher, it's essentially the stock launcher with tweaks.
wow thank you so much for your reply... i stumbled upon AOKP on droidforums before reading your reply and am actually about to flash it now - thank you for this very detailed response!!
No problem my man, there is actually a good few stable 1500MHz kernels out now and the GPU can be overclocked to 512MHz if you really want to kill your battery.

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

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
Can i use No frills CPU or any other cpu controller with stock rom and kernel?
Yes I believe you can as long as your rooted.
Sent from my HTC Sensation 4G
Yes, you can. However you won't be able to overclock anything since the stock kernel doesn't support that. You can only change governors and I/O scedulers. If you want to stay on the stock kernel but have the ability to overclock/undervolt, you can try SebastianFM's kernels.
I also tried to overclock my CPU with stock kernel. Is does not work and changing the governors just makes the phone a bit slower for me cause the kernel doesn't really support is. Try senseomaniac rom, has the bricked kernel. I am using now and works great.

You don't have to change ROM to use another kernel . If changing the governors makes your phone slower, you probably tried 'conservative' or 'powersave'.
Yeah I know for only changing kernel, but is much easier to flask complete rom then only kernel, kernels differ and are many for different phone roms made for spicific phone then kernel will work. I had screen off governor set to 1cpu and 192 fq, made the unlock slow

No i was unable to use No frills, i set min to 192Mhz, in the application it says 192Mhz but actually it stays at 384Mhz.
I think he meant stock rom. You need a custom kernel to change the frequencies and voltage, that includes lowering the lowest possible frequency (384 to 192).
Yes, i apologise, min was 384. Didnt pay much attention to the numbers
I'm curious of whether it's okay to run no-frills CPU with stock JB, as it doesn't seem to have a CPU governor.

Thanks!
On the stock kernel, it won't do you a ton of good... And you will have to be rooted to use it.
thanks, I'm rooted.
The reason it won't do me a good must have been that the stock already has a governor or something ???

Stock kernel doesn't allow for under/overclocking... I guess there are a couple of governors on the stock kernel, so you could change those around?
Custom kernels give you options like under/overclocking, different governors, different schedulers... etc.
So there's no reason you can't put NoFrills or any other CPU control app on a stock kernel, you just won't get a whole lot of choices with the stock kernel
