First off, I have an autonootered 1.0.1 NC which has been upgraded using Decad3nce's Nook Color V1.1.0_r2.
My question is which overclocking option should I try?
I'm using the Eclair 1.1 GHz kernel. It's SUPER snappy, and flashed fine! Make sure you download the one for Eclaire, not Froyo!
http://forum.xda-developers.com/showthread.php?t=925451
Agreed. The 1.1 GHz kernel has been rock solid for me for several days now. If you use it with SetCPU, you can help retain as much battery life as possible, since the 1.1 GHz kernel uses a little more power.
I use:
MAX 1100 MHz
Min 800 MHz
OnDemand
Then set a custom profile for "screen off"
Max 600 MHz
Min 300 MHz
OnDemand
This means when you're using the device, the system will automatically select a speed between 800 MHz and 1100 MHz depending on what the system demands. Then it'll throttle down to either 300 or 600 MHz when the screen is off to conserve power.
I saw a very small difference between the stock kernel and this one in terms of battery life. I still get days of moderate use out of my NC between charges.

Maybe this is an obvious question: If I flash Decad3nce's Nook Color V1.1.0_r2 rom, but then flash the 1.1Ghz overclocking kernel, doesn't that effectively 'overwrite' the newer kernel from B&N's 1.1 update that Decad3nce incorprated into his r2 Rom?
I'm using the 1.1Ghz one for Eclair. Love it... Running with no issues.
For you other guys... did you set a profile for "Charging" in Set CPU? And if so... what parameters are you guys running? 1100max/600min?
Yes it does. The only way to OC your NC is to install a custom kernel. The majority of the ROM is left alone.
This is what I did:
- Installed CWR from the maket and installed it.
- Flashed 1.1.0_r2 (changed the name to update.zip and did it through CWR)
- Flashed eclair 1.1Ghz (changed the name to update.zip and did it through CWR)
One random reboot. Since then flawless. Over 48 hours.
Question:
I did just as you did, but I installed quadrant and I'm only getting a score of 962. I never had the option in setCPU for turning it up higher than 800 in any profile. Does that indicate that I did something wrong? It's running very stable, but not the screaming speed that others seem to be getting.

Make sure that SetCPU has root access and you should be able to make the changes.
Just checked and SetCPU does have root. Still won't let me go past 800.

Flashed with the 1.1 and all seems good.
Jblues, sounds like your overclock kernel wasn't installed properly. Did you use ClockworkMod Recovery and ROM Manager to install the 1.1 GHz kernel?
Sent from my LogicPD Zoom2 using XDA App
That's what I was afraid of. OK, I'll work up the courage to try again.
I was using these instructions. Could you take a look and let me know if there's a glaring error in them that could result in failure of the 1.1GhZ kernel install?

Sorry, I didn't see a link to which instructions you were using. Really easy:
1. Put the 1.1 GHz kernel still in zip format on the root of your SD Card.
2. Go to ROM Manager and select "Install ROM from SD Card"
3. Select the zip file you just put on your SD Card
4. DO NOT choose to Wipe Data and Cache. Backing up existing ROM is up to you. Click OK.
5. You'll reboot into ClockworkMod Recovery and the new kernel will install. Should only take a few seconds to install. Then, you'll automatically reboot.
6. Check SetCPU and see if you can now choose 1100 MHz as a speed.
Hi,
I had first version of 1,1. just re flashed with r2 and then flashed 1.1 ghz kernal in the same step.
It works like a charm. Just had to re-map my volume keys like I prefer, and was good to go!
Thank you
My set-up...
I also want to put in a good word for the Eclair 1.1GHZ kernel. I'm running an auto-nootered 1.01 NC upgraded to Decad3nce's v1.10_r1. So far so good with the 1.1GHZ kernel. My Quadrant scores range between 1125 and 1180.
Bonus Tip: Like some other users, while attempting to flash the overclocked kernel I got stuck during the 'clear dalvik cache' step in CWR. Upon clearing the dalvik cache, I would hit the power button but it was frozen and would not send me back to the main recovery menu. As it turned out, I needed to wait ~30 second after clearing the dalvik cache before pressing any buttons. As instructed by another user, I tried this trick on my next attempt to flash the kernel and it worked flawlessly.
Absolutely. the 1.1 kernel works beautifulyy, and the difference is incredible. setcpu works perfectly as well. Some minor install notes
1. I had to reinstall the ADHOC fix wpa supplicant. (20 seconds in root explorer)
2. Like almost everybody, I had to switch on uSB debugging again
3. Somehow zeam grabbed hold of being the defualt launcher and i had to resent softkeys to the default lanucher using switch lancher.
All told maybe a minute of tweaking afetr the final install. it is just gorgeous. There some nice user friendsly instructions, and faster mirrored downloads available here.
http://community.saugususd.org/jklein/weblog/1350.html
Yep, those are the instructions I was using (I don't have enough posts to be able to post links, I guess.) I'll do it again tonight.
Got it done this time. New quadrant score is 1214!!! You guys rock. Thanks!
Glad it worked!

I didn't know how else to title this thread, so I'm hoping this makes sense.
Awhile ago I flashed the CM6 ROM to my Hero. I haven't added much to it, nor adjusted any of the settings. However, when my phone is not plugged in and getting charged, when I hit the End Call or Menu button to bring it from sleep mode, it takes it almost 2 seconds before the lockscreen appears.
I know that a stock Hero will awake from sleep mode almost instantly. And, when I had a previous 1.5 ROM flashed, it took the phone about maybe 1.2 seconds to awake. Is this normal or is there something that I'm missing that is causing this lag? I haven't really installed any misc apps, and I only removed some "bloatware" from the phone (safely, and ones that don't cause FCs).
Any help or suggestions is appreciated.
I know that overclocking a rom adds lag to waking up the lock screen. Did you flash a overclocked kernel or have you had this issue since flashing this rom?
I believe, when I flashed this new ROM, I reverted back to a normal clocking speed. I used to have an OC kernel of 710, but could've sworn I've gotten it back to stock.
Is there a way to get it back to stock speed, if I didn't revert it back, tho?
Bump.
Is there a way to revert the kernel back to stock?
Option
1. If you have OC kernel install, either use setCPU or Overclock widget to set your min and max.
2. If you running ASOP rom, I'm not sure ASOP ROM comes with stock Kernel or OC Kernel. If it come with stock you may just flash the ROM again w/o wiping data, might have to wipe dalvik cache and it should revert back to stock kernel. If it comes with OC kernel, then option 1 would be best.
my .2 cent hope it helps.
Unfortunately, OverClock Widget didn't do anything to fix the problem. :/ And, if it can't fix it, I don't think that paying for SetCPU will fix it either.
Is there a way I can download the stock kernel?
You cab download setcpu for free here on xda or from their website
I forgot what file it is that changes the CPU speed, but I would look into modifying that file. I also have this problem with cm6 8/17 nightly, but did not have the problem with the early test releases
Sent from my HERO200 using XDA App
Thanks a lot, I'm giving it a shot now. I do have a question, tho: when I ran SetCPU, it said that root access was not detected. Is there a trick I have to do with the phone to have SetCPU recognize the phone? I have done some searching, but haven't found much. I tried checking on SuperUser, but it doesn't list SetCPU in it. Plus, when I tap on "Log", it crashes.
Is my phone messed up or something?
Hello again, going on my 4th new thread tonight (please no comments, Let's just say im starting to like phones ) Well anyways I wanted to max out my phone with an overclock kernal but I would rather find one that's compatible rather than brick my new phone. Could anyone suggest one? I tried searching the forums for a compatible kernal with no luck. Thanks

Glitterballs will work with that. You will want to download voltage app. I think it is in the op

I got until the recovery menu when I couldn't find the advanced ULK thing all I could find is Advanced and i couldn't find lagfix. I pressed something like fix permissions and then it fixed permissions. I rebooted into a screen that had Galaxy S I9000 with samsung at the bottom. Then a robotic lady voice said something long that i didnt catch and then it rebooted into that screen again and this time i listened and it said restore operation and rebooted so i took out the battery and it just keeps doing that. Please help!!!!!
Let it do it. Let it load. Voodoo is enabling. I was wrong about the lag fix on the kernel. Do not pull the battery again
It takes a couple of minutes. Man, I am sorry I have been using a different kernel and got crossed on what lag fix it has. I hope it loads, please in future do not panic and pull battery so quickly
Alright I'm sorry i just freaked when I couldn't even get into recovery mode. I let it sit but my dad is a senior member of the site and he tells me these stories of how people have new phones and they brick them out of the box, so when I heard that weird voice i flipped. How long does it usually take?
Couple of minutes. No more then ten
Ok It's been a long time and it's still just sitting there saying restore operation. At this point I don't care about the kernal, what can I do to get my phone back to normal or even factory reset???
Wait. Do you have allot of apps? It is converting all your data
As long as it is talking we are still moving along
Respond to my pm
No I just got this for christmas. I have ytt3r's version of Darky's ROM and as i was looking over it, I noticed all these little things like texts and there was ALOT of them.
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.
I have a Milestone, rooted with Universal Androot, and then I switched over to CM7 last night. Now, I can't get the overclock apps to work. I have tried Milestone Overclock, and it says "Failed to load module". I also tried Android Overclock and it won't overclock either? Suggestions?
I have tried uninstalling/reinstalling apps, tried rerooting with Z4Root, and a few other things.
I remember having this issue once about 6 months ago, when I switched to a new ROM, and it turned out to be my root didn't unlock Nand. But now I can't find a simple method for Nand Unlock on a rooted phone.
Me too
but i use Motomizer , It work for me =)

I thought CM7 already came overclocked? You can even change all the settings (min/max/governor) from the performance/processor menu...
Sent from my HTC Vision using XDA Premium App
try overclocking via OR. however - as it was said - CM7 is already rooted and overclocked so do you want an extreme overclock or underclock?
I've had the most stability from the overclock kernels in ROM manager, but SetCPU has always worked, too. At least, when I turn up the clock speed, the phone gets hotter (my bottleneck is usually the RAM it seems). It's worth the money to just buy.
I recently update to CM7 from stock 2.2 and noticed that as well.
I suggest removal of Milestone Overclock, SetCPU in favor of CM7 included overclock as I noticed same performance gain and longer battery duration.
CM7 Already have overclock, you can configure it on Settings>CM Settings>Performance>CPU Settings...
that's what I was looking for....... apps only add to the bulk of your system... this CM7 is damn near perfect... thx.
All ROMs build from CM7 source from Kabaldan have an overclock dude just look around in the setting man if you want to overclok to 1200 MHz you need to edit 10overclock in system>etc>init.d (with root explorer, yes manually) because CM7 is overclocked to max 1 GHz

Hi! You mean you were able to overclock your phone with MOTOMIZER? can you give me the steps? i cant seem to make it work. Thanks!
If you are using any of kabaldan's CM, there is no need to you any app for overclocking.
There is a script in the /system/etc/init.d/ folder called 10overclock .
You can edit the frequencies and the voltages too.
Edit it only with linux tools or on your phone with a file manager. (Windows handles the end-of-line differently)
Hi,
Very recently i bought a Galaxy tab 8.9 wifi only (P7310), and decided to flash the 'Overcome 8.9 Series v2.3.1' ROM by alterbridge86.
Obtaining root en flashing CWM went very smooth. After full wipe + dalvik wipe I flashed the overcome rom. Still everything was fine and the rom felt very smooth. However, when I woke the tab from standby the first time, my screen was glitching so bad I had to re-boot the tab. After a reboot everything was fine again, at least until i tried to wake it up again. The same glitching occurred..
The strange thing is, during the glitching I could still open apps and everything, so it doesn't look like sleep of death issues i had with custom roms on my Hannspad.
I already tried to flash the rom again and again but every time the same issues. Someone suggested to increase the min. frequency of the cpu to 312Mhz, but this also didn't do the trick..
Right now i'm running the Galaxiansoup ICS rom without any issues, but i would really like to use the camera (for video skype) which doesn't work right now with ICS.
Does this problem sound familiar to anyone? I already searched the dev topic, but couldn't find a solution. Hope you guys can help me out!! Thnx
I added a short video to show what I mean with the glitches, hope you guys can help me out here!
I dont have any issues when use it..p7300
Try to download the file again.. Maybe a bad download make your file corrupt.
Already tried to re download (checksum verified), but unfortunately still the same issue...
Hi Ruurd V.
What Kernel do you use ?
Is it this one ?
http://forum.xda-developers.com/showthread.php?t=1344330
And did you check step
4. Install SetCPU and use to set governor to "interactive" and desired OC frequency (recommend 1.4 to start). The default governor has been set to On Demand on purpose even though it is not the recommended governor to use in SetCPU. Setting the recommended interactive governor will help SetCPU trigger the instructions to sysfs causing it to take hold. Sometimes it is finicky and a reboot can help once you have the interactive governor set with your desired frequency.
Until now I used the kernel that came with the rom. I was under the impression that the rom included the latest kernel.
I tried the kernel from the thread you posted, however the v2d version didn't work for me (no lock screen, no play store acces, home button did not work).
I just flashed the v2c version and that one works fine so far! Haven't tried messing with the cpu though, but for now I will continue using this one! Thanks for the help!
I too had some screen issues with that ROM's kernel until I installed motley's v2d kernel, so yeah, it's the default kernel.
