Thanks for all the info on here that I used to root my NC and sideload apps. I was wondering since we have seen that an OC is possible during the root process, what is needed to make an overclocked kernel for the NC?
The stock kernel isn't going to allow it, but it should be possible on custom kernels.
Then again I may be completely talking out of my ass.
Well we were waiting on the source but thats been released sp now we need someone to build a custom kernel ...and ofcourse i can and probably am talking out of my ass but i think that sounds right

See this post. I tried it one more time and I think the touch sensitivity is just my imagination. As far as performance is concerned, it doesn't seem to make any appreciable difference.
The 3630 and 3621 voltages in the power profiles probably need to be mixed and matched since the normal 3621 profile is at a lower voltage at the same speeds as the 3630.
Hello:
I would like to know if there is a way to overclock the nook hd to 1.5gigahertz. Nook HD and HD+ have the same TI OMAP 4470 processor. Is the Nook HD's processor possible to overclock. If so, can I install HD+ SDCard CM10 on HD or swap out the kernels or something
Thanks

I think if you have root, there are a few apps that can adjust the CPU frequency--currently no kernel support yet.
But heat could be a concern...
The Nook HD+ already gets quite warm when playing videos. More heat may lead to shortened life of the device.
Of course you lose warranty if you do the above..... Why do you want to overclock the Nook?
Is there an app running particularly slow? or web browsing is too slow?
If it's web browsing, putting CM10.1 on emmc should help. CM10.1 on SD card could make it slower depending on your SD card.

It may be the SD Card,but also i read that OMAP 4470 can be clocked to 1.8ghz. I have an old phone with a 1.0 ghz processor, i overclocked it to 1.7. I just need some speed on my nook, because it is capable of being overclocked
Thanks
I want overclock kernel too, but I can't find the cpufreq table under kernel source /arch/arm/mach-omap2 (stock rom)
I'm also curious as to why there's no overclock option yet. I know on my Touchpad, overclocking from 1.5GHz to 1.7GHz makes a huge difference in overall responsiveness. I'd be willing to give up a little battery life for the additional smoothness.
I tried undervolting my nook hd+, but no app worked so far, google/forum search revealed nothing of consequence.
They just leave out the "voltages" tab like described on the setcpu website.
Does anyone know a kernel for Nook HD+ that supports undervolting, or is there a possibility to change the fixed settings manually?

I suppose building myself a new kernel could work - any clues to which options I need to change?
Undervolting is really trivial as the biggest power draw isn't the gpu st all, it's the big screen. You won't get much benefit except maybe heat.

Heat equals wasted energy.
According to spec, the OMAP4470 requires around 2,6W. With a total Battery of 22,2Wh, that should matter.
Having a look in the statistics of android confirms:
Display 34% Power consumed
Game 40%
Judging from heat I would guess about 1W wasted in CPU/GPU during playing, which fits to the other numbers nicely.
So for me, there's something to win - how much remains to be seen, of course.
I want to use my nook in low-brightness environments, I've got to love reading ebooks on my phone with darkest setting and dark red font on black blackground - easy on the eye and let's the body settle down for sleep.
So, clues anyone? Do I have to look in the hardware/ti/omap4xxx directory or where do I look best, any clues how the setting might be named? Or does someone already have a suitable kernel?
Ok so I've tried almost every rom there is for the Nook HD+ even some weird Pacman rom. But reciently I decided to try out the stock rom seeing I bought mine already rooted. Its crazy but it seems faster! I was locked in a crazy boot cycle the other day with a newer rom and just decided to install stock as I had it there on my external sd card. I updated it to version 2.2.0 even tho last time I tried it, it failed (Its ment to) and everything just seems smoother. Although its has now been unrooted
I guess the only trouble I will run into is that it doesn't have trim support? I can probably see it slowing down in about 3 weeks.. How is everyone elses experience with the stock rom been?
Maybe it is just your nook that run stock better. Mine two nook and lots of others are running CM like a charm.
At least for mine nook , CM 10.2 just blow stock rom out of water and back in and out again. Smoother , faster, more customisable, better battery life...
Many say also say CM 11 kick ass as well.
I think stock runs faster, too. At first, with a fresh install. After installing my 150 or so apps it gets as slow as anything else if not slower, plus there is no TRIM support. I prefer CM11; it's pretty impressive in both speed and performance, and it's hard for me to give up the many customizations available and built-in root access.

hmmmm i was just pondering , how much faster cm11 will be compared with stock rom , just bought a HD+ , browsing is a bit sluggish and choppy when zooming in and out , using a fairly low level browser called Boat browser , i use the same browser on my Samsung Note 3 and its spot on nice and fast........i was hoping CM11 when i install it tomorrow would make quite a lot of difference .....seems as if it might not be based on the messages above !!!

No. stock rom is definitely not faster. Not by a long shot. That's crazy talk.

That's good to know, I shall install in the next few hours.
Which is your favourite version of kitkat for the nook hd+?
Antutu results are about 10% better with 10.1 or 10.2 vs stock on my HD. Didn't spend enough time with the stock ROM to tell if there was a noticeable performance difference.

Just installed the latest CM11 nightly , boy what a difference it has made to the overall slickness / speed of the Android experince on the Nook HD+ , i only paid UK £54.99 delivered , turned up today , did my homework over the past few days and hey presto CM11 has turn a bit of a sluggish tab into a bargain great experince tablet !!! i generall use my Galaxay Note 3 for my evening surfing , but i guess i will be using the HD + most evenings instead !

Maybe OP 's nook is different then most of ours . Stock rom has its magic on his nook.
But for those who is really looking for a more responsive rom, I strongly recommend giving cm a try.
My nook is on cm 10.2. It usually last 1 week for me on a charge and I do quite some reading and watching movies.

I had the stock ROM with some the mods such as rooted and install unknown apps. I was happy with it but once I tried cm10.1 yellow kernel or the cm10.2 with the archdroid optimizations, I will never go back. I would recommend cm10.2 with the archdroid optimizations unless over clocking is important to you. If OC is important check out the yellow kernel ROM.

I used to use Boat, too, but now I use Javelin. I recommend you check it out. Also make sure you run trim after you get everything installed and set up; it could make a difference.
I think on the HD+ there's something wrong with the video driver. Because I agree as well that with CM11 (any version M or nightly) the OS seems more responsive but video transitions and anything involving the screen updates is a dog. Try playing games like PvZ or some others with specific types of video needs and it's just a wreck. I made a video to highlight my Nook HD+ vs Kindle Fire (first generation slow as dirt) with the KF boot screen making the HD+ cry. You can see when I page back left after paging right the HD+ stutters trying to load the mostly empty page too.

Nook HD+ has a 1920x1280 LCD. That's a lot of pixels to render and it is a bit too much for the TI OMAP 4470 to bear it seems. Most high performance computers don't even render that many pixels.

The Kindle Fire HD 8.9" uses the same CPU/GPU and it doesn't have issues doing the same tasks. As the OP stated too the stock rom handles the load better too. I really believe we have a driver or memory management issue.

Could be. Jon Lee of the Yellow Kernel thread has done some changes to the PowerVR and Vivante GPU drivers but it hasn't really changed much as far as I can tell.
He also suggested using the "Force GPU rendering" setting in developer options but that has some caveats. It forces apps that aren't configured to use GPU rendering to do so, but forcing things doesn't always work out as you'd like. Some apps use the GPU(s) already.
We have smart people working on the kernels here and if whatever causes the graphics lag was obvious/addressable it would probably be gone. I am positive that resolution is part of the problem. I've used lower end OMAP4 devices like Nook Tablet with 1024x600 and they were much smoother.

Games aren't a really good way of deciding what's happening.
They can have different quality settings that there's generally no menu for, so its automatic picking for quality. Historically at least, Real Racing 3 would pick it wrongly and thus the game would have bad framerate on the nook hd+ needing use of a 3rd party app to force the game to lower graphics quality.

I typically agree with this statement but if you view the video I posted in my other thread about this topic it's clearly apparent that an old as dirt, 1 GHz, 512mb, very first generation Android tablet running the exact same OS release smacked the crap out of the HD+. The Nook HD+ as is, is an embarrassing device running the non-default OS. The point of this is to ensure someone is aware of this and to see if anything can be done about it.
I haven't tried an emmc install of cm, only dual boot Jelly Bean and KitKat sd cards. But they break some of my regularly used apps, hence no emmc install.
But what I haave found is replacing the stock launcher with Holo launcher really speeds up stock. And Swapps task switcher lets you access recent apps. I'm not sure how it compares to an internal install of cm though, but I'm happy enough with performance.
In reading the commits for my Note II I noticed some new commits for the HD+ that haven't been closed yet. It looks like they're enabling a 128 MB swap partition for this device.

As the title suggests, wondering if anyone has OC'd their tablet and what your speed and temps are while on it.
Mainly using mine for reading comics, playing games, and using emulators. It can handle all the emulators except it's a bit iffy on N64 and PSx.
Doesn't overclocking require a kernel mod? We are restricted to using the stock amazon kernel until / unless we get kexec working.

Agreed. Maybe one day we'll get custom kernels. We just gotta let the devs do their thing.
