I'm running Cyanogen 7.2 and use ILWT 1.8 as the kernel. No matter what I do, I never see the voltage tab in SetCPU. Any help?

Undervolting happens in the kernel, not an app. You need to install an undervolted kernel (such as Pershoot's). Also, CM7 has a performance setting so there's no need to use SetCPU, just set your max and min speeds in the performance settings of CM7 and get rid of SetCPU (it's polling has proven to be a battery drain).

The kernel specifically states in its changelog that it supports changing voltages:
"Exposed VDD levels to userspace, so that voltages for all frequencies can be modded at any time"

Sorry, that must be a new feature in 7.2. Check in CM Settings under the performance tab.

The ILWT kernel is fine for undervoltung. However, you should not use SetCPU and you also won't find any options for undervolting in a CM7 settings dialog. I'd recommend using OC/UV Beater for undervolting. I am also using it for undervolting on the latest ILWT kernel.

I prefer SetCPU for a more detailed automatic profile rather than just simply 'battery low'. But I don't do the voltage settings in SetCPU either just the profiles, for the voltage settings I set them in a userinit.sh in /data/local/ (it's provided as undervolt.sh as a reference by the rom creator) and reboot so it applies it to the vdd_levels file.

I am running Cyanogen Rc-4 with Incredikernel on my Incredible.....
I have set the speeds to 1113 and 128 using smartass governor in Cyan mod settings...
If i check set on boot will it really do it?
Or should i use Setcpu in conjunction to make sure?
Chad's kernal has a smartass governor and does this already. No need for set cpu
If you want to overclock then yes if not then no..... by default Chad's kernals are set at stock speed so if you want to overclock you will need something to overclock with.... just don't bother the min setting or smartass wont work correctly....

OK. so i followed the following guide to root my G2 from Cyan's wiki..
I messed around with the cyan settings under performance and I am not sure If my overclock settings are appropriate.
What is a safe min and max frequency for someone like me who wants smooth performance, better battery life but does not want to take too much of a risk in destroying my phone?
Also does the app SetCpu conflict with the built in Cyan overclocking options?
Thanks

In the first/second post in the CM7 thread they state a 1017/368 ondemand is recommended; SetCPU will, of course, conflict if you have both OC set from within settings and also with SetCPU running; there's no reason to use both.

Thank you good sir
the whole spectrum from minimum to maximum is completely safe... the phone has been tested to be stable at around 1.8ghz, but there's no need to go that high.
http://forum.xda-developers.com/showthread.php?p=11763114
The thread mentions "1.2ghz Overclocked and Undervolted" (for v1.0)
Does this mean that by default this kernel is overclocked and undervolted, or is it necessary to manually tweak these settings?

You have to overclock using an app such as SetCPU and you must set the undervolt using either voltage control or the newest SetCPU.

Voltage Control is optimized for Galaxy S phones. Also, Twilight 1.1.1 is much better.

Thanks. I was on 1.1.1 actually. Just flashed the latest Genocide a couple of hours ago. Not sure I'm ready to overclock/undervolt just yet either way...though this will probably not last very long. Can't seem to stop fiddeling with this darn phone ever since flashing my first rom ...

Where can i get Twilight 1.1.1 kernel ?? In the thread it's only 1.1.0... Would u give me the link ?

Come to think of it, not sure what version I was running (maybe it was 1.1.0). Whatever came with SRF 1.1 at the time.

I'm currently running the rooted 1.82 rom from here on the forum, just stock android with sense. Rooted and s-offed with AMT without a problem. Clockworkmod installed. Everything works great. And I know how to flash new roms and such.
I actually like this standard rom, but I'd like to give overclocking a try. Can anyone point me to some information, or any good place to start?
Do I have to install a new kernel, if so, any preferences?
Thanks

I'd start with setCPU. I was using it to overclock/underclock until I realized CM7 had overclock settings built in.
I'm overclocked to 1.1.
Underclocked to 386.
I was when I was using setCPU as well.
U can buy it in market or get it at blackdroid.

I tried it, but on the standard rom it only lets you change frequency between 245 and 800 MHz..
just installed Virtuous unity, it already has some oc profile built in.
don't know if I can change that or if I have to use setcpu to override the standard settigns...

Yes you could use setcpu with unity but i wouldnt, because the hole point is not to
use a java based app to oc with. here is the why and how to change unity freq

Yeah I already noticed that on the virtuous site. Can I somehow check which frequency the cpu is running on? what frequencies does the dz normally run on?
I know the max is 800, but I guess it does some downclocking?
I recently installed a new kernel on my phone, but it was one of a number of variants of the same kernel, some with SVS others with HAVS, some with CFS and some with BFS and lastly with and without call recording.
Is there a shell command I can run to find out which CPU scheduler version I installed as I remember it was HAVSand no call recording but I cannot remember if it was CFS or BFS?
many thanks
If the clue is not in the name of the kernel, not really

Guess I'll have to re-flash it and take note of which one I am using then.
Yeah if it doesnt say in about phone or system/lib/modules, I don't think you can tell.

Doesn't antutu cpu tuner support changing io scheduler?

Apparently. My cfs kernel has the option for noop, deadline, bfq or cfq for io. Still doesn't help identify cfs or bfs process scheduler though
