Which Overclocking Option?

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!

[Q] New Nook user with a few questions!!

Hi All,
Just joined the forums today after a few weeks browsing. I must say I am very impressed with the level of knowledge here and how helpful people are to others, especially noobs like me
Anyway, I got a nook color, but I am in Ireland, so I can't register it, that didn't worry me too much, because I wanted to root it, and after much reading on these forums I decided to use CM7.
My build at the moment is as follows, built with Clockwork,
CM7 RC4,
Dalingrins's OC kernel emmc 0413A,
Alsa 041411
First thanks to all the people who made the mods/ kernels etc Your work is really appreciated I am loving the nook color now with the mods.
I just have a few very basic questions, lol and I am still getting to grips with the right terminology
1. Does it matter which way I install mods/kernels etc? I understood that you had to install the CM7 mod first, but, for Dalingrin's OC kernel and Alsa, I installed the kernel first than Alsa, or does it matter?
2. If a new kernel comes out, or an update to Alsa, do I have to uninstall the old one? Or can I just boot into recovery mode wipe the caches and install the updates?
3. Same question for the CM7 mod, If I want to try some of the nightlies, can I just put the nightly on an SD card, wipe caches and install it the same way I did the RC4 version? will I have to reinstall the other kernels if I do this?
4. What happens my data and apps if I do update CM7?
5. I made a backup on the SD card using clockwork. Is this just a backup of the system files? or is it a backup of data and apps as well?
6. I am trying to learn more about this, in performance settings there is a thing called VM heapsize. Is there a recommended value for this?
7. And in the CPU settings there are a number of options available under "available governors" what are govenors? and which one is best? Is there an explaination available for each one?
That's all the questions I have for now. Very sorry if these have been answered a million times already!!

You should be able to upgrade with CWR. I have CM7 on a SD card and just add the new kernel and boot into recovery mode.
3. Same question for the CM7 mod, If I want to try some of the nightlies, can I just put the nightly on an SD card, wipe caches and install it the same way I did the RC4 version? will I have to reinstall the other kernels if I do this?

Since the nightly has its own kernel, you will need to reinstall the OC kernel.
4. What happens my data and apps if I do update CM7?

They shouldn't be affected.
I'll leave your other questions to someone else, since I haven't dealt with these issues.

thanks for tthe reply Bob.
Can anyone add anything for the last few questions?

(Q)what are the steps to upgrading to 7.0.3

I can't find a definite answer for upgrading from 7.0.2 to 7.0.3 stable. I did a tatanium and clockwork back up just in case. Have the latest clockwork recovery. But when you boot into recovery do you first wipe system then cache, installed built, then wipe dalvik then reinstall latest gapps then 4/24 OC kernel? Are those the steps? I just want to male sure that way my apps don't get erased. I'm installing to internal memory.

I would not even update to 7.0.3 to be honest. I'm assuming you are running 7.0.2, so I would download nightly 69, the fixed OC kernel (not the one you are used to using..it needs to be the ext4 one which is available by reading through the notes on the overclock kernel page over in android development...head towards the end of the pages), boot into recovery, flash nightly 69, flash gapps, flash OC kernel, Wipe Cache, Wipe Davlik, Hard reboot...and you're good to go

Why would you recommend against 7.0.3?

Well cm7.0.3 runs off of android 2.3.3. The newer nightlies run off of Android 2.3.4 which is going to be what CM7.1 is going to run off of. Both of my nook colors have run cm7.0.3 and one of them had issues (as have a few other people) while the other one ran okay, but the nightlies continued to out perform the cm7.0.3 hands down. Not only that, the newest nightlies getting incredible battery life compared to what cm7.0.3 had. In a test I ran, I got 2 hours and 6 minutes more battery life off of nightly 67 compared to cm7.0.3. It is just a personal preference, but if the option for a newer OS is available, why update to something that is older?

Well, because stable is...stable. I certainly haven't had any issues with 7.0.3 under very heavy and varied use, whereas the nightlies have their share of issues (not to mention an obvious absence of 'real' overclocking), some of which appear to not be common knowledge despite a great many attempts to make them so. =)
Certainly, if I were recommending to a daily user, I'd advocate 7.0.3 over even the latest nightlies, if for no other reason that (once properly installed) it 'just works'.
It's not even clear whether the 1.2 u-boot can be used with the newest kernel betas when booting directly from a SD card, which in and of itself is a major blocker for me (using verygreen's SD image).
I suppose it comes down to personal preference, but again, I'm unaware of any significant outstanding issues with 7.0.3. If someone's having issues, they should by all means ask for help if they don't want to dip their toe in the unstable pool.

The 1.2 u-boot has to do with the 2.6.32 beta, not the nightlies. I am and have been overclocked on all the nightlies since 59 when they first made the switch to 2.3.4...I have had no issues with any of the nightlies at all, but if you're an average user, then go with 7.0.3...like I said before I just don't see the point in flashing something that is already old compared to what is available and very stable. And why are you still using an SD card? Flash to stockkkk =) and for now, I think I will continue to swim in the stable pool.

I dont need the latest nightly i just want something stable since i use my nook everyday. Battery drain isnt an issue for me since i go the whole day with out having to charge it. So if i decide to use nightly (69) you have to use "ext4-CM7-dalingrin-OC-emmc-042411". Is that the same kernel i have to use if i decide to use 7.0.3? or should i just use "CM7-dalingrin-OC-emmc-042411"

If you use nightly 69 then yes you need to use the kernel you mentioned above. If you use cm7.0.3 then just use the regular overclock kernel. And nightly 69 is very stable. I have been running all of the 2.3.4 nightlies and they run smooth as butter for me.

im going to use nightly 69 heres the kernel for anyone else interested in upgrading

good choice and good luck

There is a misconception in this thread......Your kernel selection has to do with your version of Clockwork Recovery. The latest version of Clockwork Recovery will only boot with a kernel that has had an ext.4 script change. Older versions of Clockwork use the "original" kernels found in dalingrin's kernel page. To eliminate anymore problems or confusion. If you have not updated CWM please do so, then update your kernel to the one with the script change attached to this post. Both SD & EMMC versions are attached.....All will be right with your Nook

I upgraded from 7.0.2 to the nightly 69. Everything went fine, but I no longer have USB connectivity. Any advice on how I might get it working?

I use swiftp to transfer files over Wifi from computer use firezilla or any other ftp program to make a connection. I think it's a bug according to what I read on another post...

That works just fine. Thanks.

I have 7.0.3 running from SD card.
I tried putting the 0424 OC on and found it seemed to be causing a problem with at least one program, LCD Density after I increase to 1200. When I ran the app to increase my icon size it would freeze up the NC and only way out was a forced reboot.
Anyone else find problems like this and is this unusual.

[Q] Installed CM7, Now Milestone Overclock Won't Load.....

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)

Dalingrin Kernels for NC

I am very much new on Rooting the NC. I finally updated to the 1.3 and then used the manual nooter to root it again. However, after doing quite a bit of research, I have been seeing people posting about flashing the
" Dalingrin Kernels" ??
What are these?? and if it would help my NC to be a little more stable, or faster, could I use these?? and if so, how would I do this??
Thanks!!

They are customized kernels that allow for overclocking, and some other "unlocked" features. They are actually included in the CM7 nightlies now, so you don't have to flash them separately. You can go into the Cyanogenmod Settings to change the CPU clock in the Performance section to overclock. Other stuff that's working include bluetooth and usb host mode.
I would highly recommend just using one of the latest nightly CM7 releases. If you want to stick with rooted stock, then you should still be able to flash the kernel, I believe.

Add on to what pony said,
+ it created by Dalingrin, that's why it gets the name.
+ Dalingrin recently release new set of kernels in September, but I have no clue what news, enhancements or any advanced features added. I hope he will post the log some days.

Find the Dalingrin post in the Development section that contains the link to kernals. Use the 090111 kernal (there are two so pick the one that is to be flashed from the SD card). You can use the same CWM SD card that was used to install Manualnooter. Put the zip on the card, the card in the Nook, boot to CWM and flash. Following a reboot, you will be in business.
I did this when I installed Manualnooter 4.6.16 but you should be able to do it at any time. I coud not tell you if it makes any difference as I did not run rooted 1.3 without it.
