I just flashed the Franco kernel. Its pretty dang smooth. I think I'll enjoy it and since it is my first kernel on any device I'm very impressed to see the difference between this and stock.
My question is how do I actually use the kernel? I've got setcpu so I believe the first step is done. I know how to use it to over clock, but what about voltages?
How do y'all have it set up?

You can control your kernel with the franco kernel updater app or with terminal commands. Setcpu will indeed also allow to control parts of the kernel's functionality.
As for undervolting: differs per device. Try values that work for you and don't set them on boot before you know they are stable (prevent bootloops). Also, do a bit of reading on smartreflex voltage calibration.

I would like to boost my performance a little bit either through another kernel or overclocking or both. How do you overclock the Dinc, and do some kernels overclock better than others? Thanks for any help.
Certain kernels have higher overclocking ceilings than others but none are "better", per se, for overclocking. Check out setCPU or CM7 has overclocking preferences built in.

Ok cool.
I am running cm7 but also have setcpu, is one preferred over the other? And as far as overclocking, do you just start increasing the speed slowly until you get it where you want or it becomes unstable?

I would just use the built in OC of CM7, I've heard that using both can cause conflicts. And yes, just bump up your frequency bit by bit and if you start getting reboots or freezes, dial it back. For AOSP kernels, I've founds incredikernel to work really well, then invisiblek, then tiamat. Though incredikernel does have a lower OC ceiling than the others.

"kernel manager pro" in the market may also be useful for you. It keeps up to date on which kernels work specifically for your device and you can flash from the app. I'm currently using Tiamat 4.0.2. It will clock to 1228MHz
I'm having trouble finding a CPU app that works perfectly with this phone. I've tried setcpu, CPU master, system tuner, and nstools. What's everyone using to oc this thing?

Depends on which rom your running but in general...you should use none. Most roms already uv and oc and if u use an app it'll butt heads.

My issue is that it seems like my phone is skipping steps all over the place. I'm using cpuspy and the usage jumps between Max/min clocks. I'm kinda not digging that. Its the same with every rom i flash.

That's not an issue with your cpu app. It has to do with your governor (the thing that controls how your CPU scales). Most ROMs come with ondemand by default which pretty much does exactly that, which is jump from min to max as needed. If you want something that scales more, you should look at conservative (for better battery life) or lagfree/interactive (for better performance). Lagfree/interactive are only available on select kernels though (whereas conservative is almost universally available). Streamline definitely has them and I think synergy does too.
Also CPU apps don't butt heads with the ROM/kernel default settings, it just overrides the default settings.
Yea I figured that but this is the first phone I've had where on demand performs that way. I've had a nexus s, epic 4g, evo, and a g2 and they all scaled across the steps ondemand. Ondemand on this phone works like the min/max governor. But your right conservative scales across the steps well. Just a bit choppier. About to install nstools and mess with the threshholds and whatnot.

I'm new to the Galaxy Nexus and I'm coming from an OG Evo that I was using SetCPU with....
I wanted to see if anyone could recommend settings for the Kernel Updater...I'm looking to keep the battery going as long as possible in between charges.
also, if I use this app then I don't need to use SetCPU, correct?
no you dont need set cpu.. everything u need is within that app.

yea that's what I figured.
any setting recommendations?
I tried a few but just wondering what others are using...
I use default and it goes pretty good

I personally use 192 to ~1200 MHz. With SmartReflex on (disable it if you want to do custom UV).
Play around with Generic Hotplug. It may be good for you and it may not.
I have my governor set to ondemand (it was on interactive but Franco recently changed it back to ondemand as default)
TO EVERYONE WHO USES franco.kernel updater
Please be aware that the "Turn off Thermal Throttling" feature in the latest franco.kernel updater app actually Turns on Throttling down CPU frequency when it reaches more than 70 degree C.. So just remind it that it is Vice Versa
I use ondemand governor, 384 min 1420 Max. Battery life is quite gd for me

Is there a way to set different voltages and MHZ values on two different 'profiles' ie battery saving (regular everyday use) vs performance (streaming hd movies) using Rom Control on AOKP?
I recommend flashing ktoonsez kt747 aosp kernel if your going to be undervolting. Then in ktweaker you can save and load voltage setting profiles.
i'm on that kernel right now. no option. to be fair i haven't updated since mid august.

ktweaker was added around build 8/30.
If you are still on an old kernel try out setcpu.

SetCPU profiles are exactly what I wanted...but that doesn't seem to be the case with the tkoonsez rom and kernel? Or is that not the case anymore? When I used it a while back I remember specifically reading NOT to use SetCPU
You can always try system tuner in the play store

I just updated the fku app, and it keeps resetting my cpu setting and governor back to default (ondemand and 1034 as max mhz). My phone didn't hang or reboot, I just get a message from SU saying it granted fku permissions. How do I prevent this event from happening?

It's only worked right for me with super su. Did not work with super user for me ever.
Silly question, but are you using Franco's Kernel, and if so, what nightly or milestone?
You should also get in contact with Franco, he posts here on the forums, so explain your issue in the appropriate sub-forum (Maguro, Toro, Toro-Plus) I'm sure he could help you more
