[Q] Overclock?

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.

Overclocking?

Hello,
I've seached as much as i can and i guess as a rookie i am still having a hard time understanding all of the benifits of overclocking other than speed. I am basically Autonootered 1.01, would it do me any good? If so which Kernel should i go with or is this for the more advanced?

Do you know what overclocking is? If not read this: http://en.wikipedia.org/wiki/Overclocking
After reading that you still don't understand how OCing will benefit you, and the dangers of it, I don't know what else to say.

As of 24 hours ago I purchased a nook color rooted it, applied the 1.1 update zip, and overclocked the nook Using the 1.1 ghz kernel honestly I haven't notice any speed increases because I did everything straight out the box but quadrant scores are very high

There are no other benefits of overclocking other than speed. That's the purpose of overclocking. Stability and battery life is usually the trade off. With the kernels from http://forum.xda-developers.com/showthread.php?t=925451 I would say the risk of instability is very low. Especially since there are different levels of overclocking with those kernels. As for battery life, it doesn't feel like my battery is draining any quicker but I haven't compared my run time before and after overclocking.
I have had my NC since just after Xmas and I can tell you by my own experience that things were noticeably quicker when I went from an Autonootered 1.0.1 stock (800 MHz) to 1.1 GHz overclock. Before I overclocked I had been running stock for at 2-3 weeks. I mostly noticed the speed increase loading eBooks and websites (using Dolphin HD).
Personally, I would just go and try the 1.1 GHz kernel (kernel-1100mhz-omap3630.zip) within the link above. There a lot of people running on that kernel, including myself, that I don't hesitate recommending it. However, I would download all the kernels so you have them all handy just in case so you can flash to another kernel, such as stock, if for some bizarre reason you can't boot or have stability problems with the 1.1 GHz overclock.

As I stated I wasnt sure of any other benifits, other than speed with overclocking. But I do understand what it is. The majority of the threads i found that people were discussing it were either Froyo or more advanced than autonootered. Just trying to do my homework.
Thanks for the help guys.

Tegra 2 overclocking

I already postet this in the Atrix 4G section, because they have a thread there about this topic. But they are discussing more about the locked bootloader than about overclocking and as we don't have such a thread here, I will start this one.
Perhaps you think overclocking actually does not make much sense on this device atm, as it is really fast, but I always like to get most out of my hardware that is possible.
I dont think, I would enable overclocking for everyday use now, but it would be cool to be able to do so if needed. At 1200 MHz as Nvidia had planned for the Tegra2 3D the Phone would for sure even beat the Omap 4 in Optimus 3D.
I am totaly new to Android and also to Linux, so I am not sure if this is helpful, but I have seen something very interesting in the Optimus 2x review at Anandtech.
I dont know where these variables are stored and what is needed to, but for me it looks as if we are able to change them, overclocking should be possible on the Optimus 2X.
It would be great if some oft the developers here could look into this when the Optimus Speed finally has been shipped…

I was wondering the same thing. So i checked other Tegra2 powered devices. And as far as i know none has been overclocked yet. Correct me if am wrong.

So far no overclock is needed since this phone is reaaaaaaalllly fast.
But I am sure as soon as it needs some extra power developers will figure out how to do it

Michael Huang (author of SetCPU) has just overclocked the Xoom tablet today. Now, while the Xoom is a Tegra2 device, its kernel is (apparently) Google based whereas others are nVidia based.
In overclocking the Xoom from 1GHz to 1.5GHz though, he saw about a 1/3rd increase in performance on Linpack and Quadrant. Looks promising so far.
Watch the video here http://www.youtube.com/watch?v=cLNjHyAi8BI and follow Michael on Twitter here: http://twitter.com/coolbho3k

The Reason to Overclock the Atrix in my opinion is as follows
The Linux Based Webtop is slow in reviews
So when pluged into mains power it would be very usful to overclock the device to make the most of the webtop with less lag issues making the device far more usful if you need/want that feature.
Maby possible to make a custom dock (stick fan on it) and clock higher

I'm more interested in underclocking, especially when screen is off with a screen off profile in SetCPU. What do you think is the lowest possible frequency I could set it at?

You can put all the way down. I use the same settings in both my N1 and the 2x. Saves some juice. What I really want to see is custom kernels, pref undervolted if its possible.

According to the SetCPU changelog, overclocking/underclocking is now possible:
2.1.1 - Fixed an issue with profiles backup in CM7.
- Added support for the Motorola Xoom, Atrix 4G, and other Tegra 2 devices.
- Fixed various bugs.
- Tablet optimized UI and more profiles coming soon!
2.1.1a - Fixed the 0 MHz display issue on some devices.

How can you overclock with SetCPU then on o2x? Believe only the powersaving underclocking on demand is working.. overclock needs more work i believe.
The Xoom has been overclocked, but apparently the kernels are from google, which made it easier.
If anybody knows more about this, please correct me

The kernel must be adjusted to make overclock work. I got to read myself into this, but perhaps someone else knows already everything to it .

GPU
i wonder if the gpu can be overclocked, would be nice if it was possible too just OC the gpu and compare the results. Or do you think that the CPU and GPU clock speeds are somehow linked???
Any thoughts?

bumping cause im curious. Can any one please answer ?

well this is arm so id day they are linked
are we able to read the clock speed of hte gpu. does is change?

Look at the date mate
The GPU is not linked with the CPU. The GPU is overclocked in different kernels. Spica's kernel allows on the fly overclocking of the GPU.
After having this device for over a year, the only time i needed OC is for 720P Youtube or Youtube HD app. No OC on the GPU has ever been needed. Yes i have been playing around with 1.2 and 1.4, but they just consumed battery more than giving a better experience. I would go so far and say undervolt it and put it on 900Mhz.

what kernel can i over clock it?

hey everybode!
i wanted to know i have rocket rom and i want to use setcpu to overclock my kernel
and sebastian is max to 1400 is thers good kernel that i can play with it till 1700mghz or 1900?
but it need to be stable

Abyss goes to 1700. My CPU can't take it, sadly

The stability is dependant on your hardware; some chips can only overclock to 1500Mhz and some can overclock all the way to 1900Mhz. It is not something the kernel has a say over.

Don't all of the notes have the same cpu? Why can some be overclocked and others not?

They all can be overclocked, but how much is a different thing altogether. It's quite simple really, not every chip manufactured is of equal quality; some chips have more imperfections. The more imperfections the less it can be overclocked before it becomes unstable. It's the same thing as on PCs, too.

Stable is it when you do nothing and use it in originally form. Overcklocking need more Power more power is less time you enjoj your note!

Generally these chips are made to tolerate a certain speed, and because of variability, the manufacturer drops the speed tolerance to ensure overall quality. Some will still be able to manage 1500, 1700, or even 1900 (although rarely, I'd say). Just about all of them tolerate 1400, so very few are defective at the stated tolerance. With 5 million, you will get a few, however.
This is one of those rare occasions when statistics have a benefit in the real world!

There are many out there that will let you overclock. Search the Android development forum.
Like most, I have flashed heaps of times, probably at least four or five times a week when I first got this wonderful Note, but in the last month or so have only been tempted to stray three or four times. Personally Franco 6 is best for me, because I favour battery life and stability rather than overclocking (1400MHz is not bad as a standard!!)
I would encourage you to try a few for a few days, as long as you backup often you should have a great experience!

Are all kernels capable of overclocking?
Is there one that overclocks the best?
How do you tell how high you can go?
Do you jusy keep overclocking until the NOte stops working?
If so, there must be a fine line.

Stock kernel isn't capable of overclocking.
One way to tell is to download things like SetCPU which detects the range of the clockspeed. Another way is to simply read the description of the kernel thread.
How high your phone can go is an individual thing. You need to overclock in slight increments (say 50mhz at a time) and run a stability test to see if the phone crashes or not.
You DO NOT pull the slider all the way to 1.9 ghz and "see" if anything happens. If you fry your CPU, do not come to us for help.
This is why I don't like overclocking, it's a waste of time to run the stability tests, etc.
In summary, you need to raise it a little bit, and run stability tests and repeat the process until your phone crashes. At that point, you'd know the last safe-stable clockspeed that your CPU can take.

Thanks!
What do you recommend for a good stability test?

I'm on franco.kernel v10 and OC to 1600 using Tegrak. Tegrak runs the stability tests automatically and reverts to stock 1400 if unstable or a reboot occurs.
I tried 1700 but Note rebooted after about 2 minutes. Booted right back up at 1400 with no problems. Re-set to 1600 and running smoothly.

[Q] Best Galaxy Ace Overclock Frequancy... And something else thanks

Hey guys
I know their probably another thread out there with this in it but... Yeah. But go ahead troll me lol, im still a bit of a noob.:silly:
Anyways, i have a Galaxy Ace s5830. I have Beats with smooth sense ROM. I had it upto 883MHz Yesterday but after i turned it off then back on ROM Toolbox reverted it to 806MHZ. 883MHz seemed a lot faster even though some people get theirs close to 1GHZ
My phone afterwards rebooting had issues such as the phone becoming un-responsive when i was even doing nothing (maybe the overclock to 883MHz had some short term effect?) But the phone seemed fine after safely turning it off then back on several times. Still works perfectly i got scared when it started to become un-responsive. But it works well now i have also used pimp my ROM, and the scripts work like a charm. Especially the call quality one (it uses bravia engine or something?). But with pimp my ROM wi-fi and network tweaks it completely broke wi-fi saying wi-fi connecting... Then saying under the network name 'Error'. Dam it took so long to get the IP address then said error like i said lol
At the frequency 883MHZ the phone seemed stable and faster than ever before, i did change it in small increments
So just wondering, what is the safe and most reliable frequencies to set it at? I currently use 225Min and 806 Max. With the userspace governer.
I know the terms of ' Safe ' and overclock don't mix (sorta like water and my dads S2 :crying: ).
Im also considering buying a 2450MAH battery from ebay for about 5.99 AUD. Any suggestions on should it be okay and better? But i mainly would like to knwo about the overclcoking lol.
So yeah, basically what is a good frequency to set it at? Is 883MHZ okay? Am i going to fry it out or completely brick or damage the phone or cpu if i set it at 883MHZ? Would love to buy a new phone but i need to save im only 14
So yeah please help me and you could help others too. Please be welcomed to troll me
I plan on having this phone another 3-4 Months before i consider buying the S2 or Galaxy note when their cheap (like really cheap)...
Like i said please help, and feel welcomed to troll me when you do help :highfive:
Man i feel like a Rebel when i overclock

That battery is a fake and has been confirmed as such. If you want a higher cap. battery get a 1500mAh or 1600mAh. I don't like messing with the clocking, good luck to you.

Thanks

Right now I am just using the stock one. I personally wouldn't change my battery to anything other than stock, but people have reported that 1500mAh or 1600mAh work well. I wouldn't use anything that has a higher capacity than that though. Also, if it's very inexpensive it's probably not real.

Clocking actually goes on the rom. I've seen people having OC over 1gHz & still stable with the mad kernel but I gave up clocking as I didn't see much of a difference & also underclocking started giving me FCs on some heavy apps while it was all fair in the unclocked state. And again, there's no such thing as a best frequency. You find your own values. What works well for him might mess up your phone rebooting all by itself. Stock batteries are always fine & they also keep you under warranty. Anyone ever wondered why the phone manufacturers didn't implement clocking as a part of it ? Stability is the word. I've seen here, I've seen there. East or west, stock is the best ! Try keeping as close to stock as possible, just to have that extra touch of safety & stability

Hello all.
I was reading this thread and became interested in overclocking. In my case my device is:
Samsung Galaxy Ace GT-S5830L (labeled as GT-S5830 by CyanogenMod)
CyanogenMod-7.2.0-cooper stable (Android version 2.3.7)
Kernel 2.6.35.7-perf-CL882825 ([email protected] #21)
I was checking in CM settings -> Performance -> CPU settings that I could adjust min and max clockspeed, but in max frequency the maximum one is the same processor's speed, 800 MHz. So my kernel doesn't support overclocking.
After a search in the forums I found there are plenty of custom kernels for this legacy device. But I'm relatively new to the kernel world, so I wanted to ask you for advise. What custom kernel could I try for my device for overclocking? Or King Android, what custom kernel are you using?
It'd the first time I do the overclocking stuff, I'd like to try it to see if some higher quality mp4 videos (which are run by MX Player only in software acceleration) can run better, as well as some games and emulators.
I'm also kind of a noob as you can see. If you want to troll/scold me...
Thank you all.

Hi you can try FireKernel or BlackHawk kernel. Use the search function to find them easily. Both supports Overclocking and are made for CM7. [MAKE SURE THEY SUPPORT YOUR S5830L]
At the moment I'm with Democracy ROM which is based on unofficial CM7 and I don't really feel the need of overclocking. It is all smooth with firekernel at
Min 245
Max 806
Governor smartassv2
Sent from my... oh wait, who cares?

I did my search.
Maybe I forgot to mention I haven't installed a custom kernel before... Does the kernel come as a file itself, or along a CM7 custom rom? And if it comes as a file itself, how can I install it? I already mentioned what CM7 I have installed. It's the "official" stable one.
Would OCing help to improve videos and games performance? i.e, faster, no lag...

You can set it to whatever your phone can handle. Mine can't go past 844Mhz otherwise apps start force closing and such. If your phone is completely stable at 883Mhz then you're good.
As for the battery, no. It's a fake. Buy a 1500mAh like I did. Works like a charm and it brought 3. Lasts a little longer and it's really amazing. Had it for a while now. Still have one in the pack, only been using 2 when I don't get to charge my phone. Really handy.

OCing helps the phone over all. But remember, without much free ram, OC won't really change much. You need a balance of ram and CPU. Like me, I use swap and OC to 844Mhz. Even if it's a low OC, it's still better than nothing.

1. @SuperAce609: I have 104 Mb free RAM out of 278 Mb total RAM. Mine is Galaxy Ace S5830L with CM 7.2. Would OC work for me? Up to what frequency?
And how can you have 600 Mb of RAM? Is your device really an Ace?
2. There's still a doubt I haven't been able to find out myself: does the kernel come as a file itself, or along a CM7 custom rom? And if it comes as a file itself, how can I install it? I was suggested FireKernel or BlackHawk ones...

Any help?

1.- Every Ace is diferent..some Ace's can go up to 960 Mhz while other just 844 Mhz, the thing is: try it yourself overclocking in small jumps. Swap is a small amount of memory of your SD card, that Android use it like if where RAM, but decreases SD card life...
2.- Some Kernel came Built in on Some particullary ROM's but generally cames on a CWM Flashable zip; FireKernel & BlackHawk are specially for CM7; In my opinion FireKernel is the best... And there are others like Battery Extender Kernel or NimsKernel but these Kernel are only for Stock ROM's...
I hope you find useful my info...

Thank you, Blake2893.
Then there's just 2 doubts left, if you don't mind.
There's a fair number of custom CM7.2 roms with FireKernel in the developer forum. Is there one you or someone else could say is the best in terms of stability and least number of bugs? Or is that something I should test myself in the S5830L?
The Ace S5830/S5830L has 278 Mb total RAM by default. If I understand well, you're implying I could modify SWAP partition in order to increase RAM and, probably if lucky, with this make OC work better. How can I do that? Do I also need a custom kernel/rom for that?

The best stable Roms so far are the stock GingerBread based ones... but if you aks me about CM7 there a few like Apocalypse rom(ICS styled ROM) with the FireKernel that suports swap I think...
and for Swap you only need a Kernel with Swap enabled and a SWAP Partition on your Sd card...

lets see im fine and stable with 979 mhz without reboot for 9 hours
overclock is depend on your hardware

Using CPU high frequencies is not recommended, your device's life will be reduced considerably
