Overclocking CM7

OK. So I am sure I am missing something obvious here. I've done a ton of searching and reading, but I'm still at a bit of a loss.
I am running CM7 with dalingrin's OC kernel flashed over the top of it. I see tons of people overclocking to 1.0 and 1.1 GHz, yet I can't seem to options for doing so.
In CM7 settings under performance, I have options for 100-950. I can O/C to 950 and that's great, but how do people try settings above that? I tried setCPU, but it seems to cap out at 950 as well.
What am I missing?

You need to get a different kernel, such as Dalingrin's, from the android development forum.

Hi,
Looks like you didn't successfully install the overclock kernel, see:
http://forum.xda-developers.com/showthread.php?t=925451
for instructions.
I have been using the CWM install method and am running CWM7 RC4 with
the interactive governor between 300 and 1100MHz.
I usually install the updated CM7 along followed by GAPPS then the
latest OC kernel. Perhaps you installed the kernel before CM7? CM7
comes with its own kernel that overwrites existing kernel when you install CM7.
Hope this helps,
Peter

That is odd. I have never had any issue like that with any of the oc kernels.
My one and only question is if you a sure you flashed the right one successfully?
http://nook.handhelds.ru/dalingrin/kernels/033111/
Note that there are 2 kernels for each ROM-
one is for internally installed (emmc)
One is for sd card installations (sd)
I do not know if any errors would show up if you flashed the wrong one or if there was an error with the download.
My suggestion would be to try again and see if it works.
My response may be too basic- I don't know your knowledge level.
One thing though- IN CM7 it is best to NOT use SetCPU or other apps to change cpu speed, or at least that used to be the case. I don't use them anymore.

Ding ding ding, we have a winner. I was using the SD version, as I had a bootable CWM SD that I used to get into recovery. Once I loaded the emmc onto the SD card and flashed that, they showed up.
Thanks for all of the replies.

Nice!
Glad I was able to help-
Usually I am just getting all kinds of info and help for my own stuff here. Being able to pay that back is a good thing.

Be sure not to flash a cm7 nightly after you flash the kernel. If you do, you will flash there stock cnn kernel over the oc'Ed kernel

Actually a good point-
Nothing wrong with updating to the latest nightly but you WILL go back to having the stock CM7 kernel again.
Re-flashing the oc kernel fixes that problem, of course, but you'll need to reset max cpu speed and governor again.

1.1.0 or 1.2?

Hello all. I just bought my NC a few days ago and it is running 1.1.0. Do I want to update it if I want to throw Honeycomb or Gingerbread on it and overclock? Basically, does 1.2 cripple the NC when it comes to doing the things I want to do to it?

No. You can try out 1.2 safe in the knowledge that you can wipe the machine and apply any rom you want afterwards.

You also might want to consider keeping it stock at 1.2 and running something else from a SD card -- easy to do. Once you've found a rom you like (CM7 stable is really very good) you can flash it internally if you like.
I run CM7 from my SD card because I bought the extended warranty on the Nook and I wanted to keep it stock. You don't even need to root it.
By the way, 1.2 is an upgrade, but it's certainly not stunning. CM7 is far more advanced and stable.
There's an excellent thread for setting up and SD card -- search under "Size-agnostic" to find it.

try out stock 1.2 first. it's much better over 1.1, but u will still want to root it. u might stick with 1.1 because 1.2 root still has some minor issues. fwiw read thru the MN thread.

[Q] Just bought a nook color, couple rooting questions

So I just got a nook color and obviously I want to root it, but heres what I would like to know. Should I upgrade to 1.2 first? I figure if Im going to root, then I dont need the features of 1.2 If I root and install CM7 with CWR and all that good stuff to the eMMc can I put it back to stock nook at any point (like in case I want to return it)? My understanding is that autonooter is to install android to an microSD card and you still have stock nook when not booted from sd, correct?
Im not looking to run HC and Id think Id like to keep the features that the nook has, but is booting off SD really that slow? Can I still over clock if booting off sd? Besides CM7 is there a stable working froyo or GB rom? I run Chevy's SS 5.2 on my D1 which is GB with some tweaks and would like something similar.
I know its a lot, but id appreciate the help, search for all of these is very overwhelming as most of the answers are buried in 100's of replies.

Running from SD can be at least as fast as eMMC and does not require rooting, and you can upgrade stock without worrying. The "Android Odyssey" blog post linked in my sig has links to all the resources you'll need for a fast and painless CM7 set-up.
Maybe you'll still want to root afterward, but I started out intending to just 'try out' CM7 on SD, and couldn't be happier with my system as-is.

[Q] New user questions

I will be getting a refurbished Nook Color this x-mas and had a couple questions i need to ask before i root and install cm7. My first question is should i update the stock firmware to 1.4 prior to rooting? Secondly, If i so update to 1.4 should i still follow Eyeballer's guide to root my NC or do i need to find another guide?

You do not need to worry about the 1.4 update. If you run CM7 off either a SD card or internally it doesn't matter. When you boot to a card it does not see the stock ROM. If you run CM7 from the internal eMMC you will be replacing the stock ROM anyway....

Thanks for the info!

I do have another question, i have seen tutorials talking about installing Dalgrins overclock kernel, do i need to install this with the newest CM7.1 mod?

No need to but you may want to install the NookTweak to manipulate usb or audio settings.

Will do, thanks for the help!

[Q] Upgrade to Gingerbread a mistake

OK GUYS. Kinda noob here, need some help.
-On Captivate (obviously)
-Was on 2.2 Froyo
-Rooted phone using superoneclick.
-pleased overall. Looked into new ROMs, but couldnt quite get an understanding
-Ended up updating to Gingerbread 2.3.5 via kies mini
-killed my root access
Here are my issues:
-Cannot figure out how to root
alternatively, cannot figure out how to revert back to froyo to root, then download and apply Cyanogenmod7, which is what i actually want
-When i was rooted on froyo 2.2, i would try to use ROM MANAGER and it kept saying the SD needed to be mounted, even though it was.
Basically, if someone could either copy-paste (or provide a link to) a guide as to how i can go from 2.3.5 Gingerbread to Cyanogenmod 7, i would be forever greatful.
I want to be able to overclock my cpu for better proformance, plus have FULL costomization abilities. PLEASE KEEP IN MIND I ROOTED MY CAP WHEN IT WAS 2.2 YESTERDAY, AND THIS WAS THE FIRST TIME I HAVE EVER DEALT WITH ANY SORT OF MODDING.

Take a look in the development section.
You'll need to run one of the one-click stock ODIN or HEIMDALL packages with CWM baked in to get you a setup that will work for going to CM7 (there's one in my sig if you need it).
Once you do that, look for the CM7 thread in the Development section. It has a step-by-step guide to flashing CM7 (basically download, backup, flash).

well if you used super one click to root it back then, i would use super one click (new version) to root it again...
cm 7 has instructions.

if you really wanna know how to root 2.3.5...it's in the general section.

ok guys.
I used heimdall to go back to froyo
Then instead of cm7 i flashed cognition through clockworkmod rom manager
now im running on cognition 4.5.3
however, all overclocking apps i try wont go beyond 1000mhz.
im trying to get it to at least 1200.
Any ideas? Fixes?
thanks in advance. you guys have been very helpful.

You'll want to take a look at the kernels compatible with Cog, I'm not familiar with Cog, so I can't give you any direction as to which one you could try

Froyo isn't as freaking kernel picky as gingerbread. Any froyo kernel will work, just remember if you use a reoriented I9000 kernel you will need to flash an I9000 modem as well. This will also give you hsupa at the cost of audience chip support.

upgrade again to uckj3 firmware with bootloader then flash boog kj3 kernel it have cwm recovery
after flashing recovery
wipe data and cache
install cm7 from recovery it will fail for the first time again go to recovery and install cm7 after installing cm7 wipe data and cache again reboot the phone it will take time as the phone will regenerate dalvik cache
cm7 is pre overclocked to 1300 mhz you can increase the overclock to 1700 mhz by flashing glitch kernel

It isn't pre overclocked, it comes at a stock 1000 MHz or 1GHz.... Then you can OC with Glitch and stock I believe. But it isn't 'pre overclocked'
Sent from my SGH-I897 using xda premium

it is pre overclocked we just need to set it through cpu setting or set cpu like apps

If you need to set it, it's not PRE overclocked. The stock kernel just comes with the ability TO overclock
If it was preoverclocked you wouldn't need to set it with an app..it would be oc'ed by default...lol

I am really struggling as to whether it's worth upgrading to stock GB.
I mean the "newer and better" is sitting there beckoning me with its siren song, but there appear to be lots of little landmines that people are then regretting the upgrade.
1) tethering mgr error
2) bad battery life
3) random shutdowns/reboots
etc, etc
Are the "benefits" really noticeable such that it is worth taking the risk of the landmines and the time/hassle of trying to fix them?
