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.

This is probably a stupid question but I'll ask it anyway. I've noticed my phone draining lately (or maybe it's not, I'm not quite sure what the battery life used to be xD), and I recently overclocked my phone to 1.25 GHz (my profile on SetCPU is ondemand), does overclocking affect the battery that much?
I run Froyo (rooted with wifi fix and the 1.25 GHz kernal)
I'm using an ultra low voltage kernal at 1ghz and haven't noticed a difference, if anything it seems like it's better.
I guess it probably largely depends on what kernal.
I've been overclocked for 4+ months. The first month before I rooted, I was getting around 16-18 hours on a full charge at the stock 550 speed. After I rooted, a lot depended on the rom (lesser so) and the kernel (more so). I think the best performance I got was on ChevyNo1's SS rom (2.1) with one of his kernels ... 40+ hours overclocked conservatively at 800. My first shot some time back with CyanogenMod got me 3 hours with the early Bekit kernels but the past several versions up through 5.0.8 I was getting about 30 hours clocked at 800 with a jdlfg kernel. Now on Froyo I'm getting close to 30 hours again conservatively at 800-1000 ... which on a 2.2. rom is more like 1200+ since its faster.
So, in short, my battery life has significantly improved while running faster than stock. But no 2 Droids are identical in terms of how a rom and/or kernel perform. With 2.1 roms my Droid seems to like jdlfg's kernels, while on 2.2 the P3droid kernels do good. But that's what I found out via a lot of trial and error, not anyone's post saying "You must try ______'s kernel (or rom) as its da bomb!"
I would like to include that the post above by "cvhovey" provides some valuable information that might interest you and suggest anyone untreated in this thread to read that post.
Using an application like SetCPU you can throttle down the processor speed when the screen is off, this reducing heat and gaining better battery life. This doesn't mean you will get better battery life if you use your phone all day and never turn the screen off. But is totally worth it because u feel like I'm getting awesome battery life, plus an amazingly fast phone because SetCPU will overall me to my personal preference of 1100mhz on demand.
The answer to your actual question depends on how well you set up your phone preferences according to what benefits you the most, and what method of adjusting processor speed. I only mentioned one here, there are mire ways than just an APK.

1+ on that. But how one uses SetCPU can also make big differences, such as which governor is selected. SetCPU at 400-1250 with the Performance governor will essentially run at its highest speed all of the time (if I'm correct), whereas with the Conservative governor will ramp up from 400 to 1250 at a slower pace, or at a faster face with Ondemand.
This thread can give you some helpful tips: Battery Saving Techniques - Theories in Test
Alright, thank you for your help ^^
i used SetCPU and my phone had continuously reboots...
I just had to uninstall it..
Were you using profiles in any way? A specific ROM? I've had similar a experience with certain ROMs (specifically UltimateDroid).
Best guess is that it just didn't play nice with the modded kernel.

I am using Setcpu on my motorola droid with rooted FRG22. Why wont it let me overclock it higher than 800mhz??? I'm kinda new to doing this and wondering if I'm doing anything wrong. Thank you
[A] Overclock answer
Yes you have SetCPU and your phone is rooted. However, you're missing one more piece to the puzzle. In order for you to clock over 800Hz you have to install a kernal cooresponding to the voltage and what you want to overclock it to. I recommend you googling(haha) p3designs and choose a kernal you want to try. Instructions are on the site as to how to install. I currently have a low voltage of 125Mhz overclocked at 1Ghz. Hope that helps
Question for you Stephen, with you running 1.2Ghz on your droid, has there been any istances of freezing thus far? I was tempted to go higher, though I stuck with 1Ghz to be safe.

The right approach to overclocking is not how fast can you go, but how low can you tolerate? Most Droids are stable to 1.2 ghz. Some can go higher, some can't. I'm running the "stock" 1ghz kernel that comes with Sapphire rom. However, I have it choked back to 800mhz. This gives me 36 hours of battery life on light-moderate use, (3G off, wifi on) but also lag-free performance.
This is chevys 1.25 medium voltage, only reboots were with watching movies online.

I understand what you mean. I've done the trial between 800Mhz and 1Ghz. I have emulators now and I liked the performance on the 1Ghz more because of the speed, so I kept it on 1Ghz. I haven't had any battery drainage issue and all. I liked my low voltage 1Ghz kernal.

Is this the site you tried accessing the kernals? I did a test and downloaded the kernal zip fine.
That does sound impressive. I'm curious to try that out even more so now.
What are the benefits of OC/UV (particularly for CM7)?
I know of improved performance due to OC, but what does UV do in regards to performance. Also, how does an OC/UV kernel compare to one without the option?
your processor doesn't need as much voltage as the stock settings--undervolting lets you save battery
personally i want to know.. do you have to UV to OC?

You can do either or both but don't have to do both. At some point UVing will cause a crash. Right before that point it can cause performance issues. See the link below for instructions on how to find an optimal UV level to maximize battery savings and performance.
http://forum.xda-developers.com/showpost.php?p=10936691&postcount=1102
OCing improves speed but can also cause stability issues. For a captivate this usually isn't a problem until you get past 1.2 ghz. After that, it depends on the kernel but I have yet to find a kernel that is completely stable past 1.2 ghz under stressful conditions. Samsung designed the processor to handle 1.2 ghz and in theory it can go up to at least 1.6.
Like everyone before me has said, OC will make your processor work more (which will eat up more battery, and send the temps a bit higher).
UV is a way to "fix" that problem by controlling the voltage used by each Mhz/Ghz range. The mini guide that QuarkGluonSoup posted is a great way to start off.
Most Captivates start have random errors past 1.2Ghz, but the highest I've seen (stable) are 1.4Ghz.

Odd as it sounds, my battery life on CM7 is close to 50% better when it is OC'ed to 1.2 ghz and UV'ed than it was on the froyo ROMs under the same conditions.
That really is odd :S I think I'll try it myself.
Cyanogen 8? Is this next? Or is this in the works? Also is 2.3.5 next and would it be numbered a different version when Ice Cream comes out? Also is anything coming from the devs to overclock to 800 yet?

It's been done. So very very few phones are even stable at 800, and those that could generally performed worse in benches at 800 than at lower clocks. Many of these devices bootloop above 700.
Cyanogen 8 will not come out yet since will most likely be ice cream sandwich. I am not even sure is 2.3.5 will even come out and no the devs can not overclock this device to 800mhz because is 768 is the limit of the processor. Most people's phones do not even run that smoothly at 768 anyways. If somehow the dev found a way to overclock it to 800 (impossible btw but this is just a what if kind of statement) since the processor can not handle 800 it would just overheat the thing and cause crashes.
Also, on a side note, this should not be in the Development section. This should be in general or Q&A
This belongs in Q&A for future reference.
CM8 will be next, obviously. It will be based on Ice Cream Sandwich, so no, it won't be in development until ICS is released to AOSP so that the CM team can start using that code. 2.3.5 is an update coming out soon for the Nexus S 4G that fixes wifi and network speed, as well as adding more secure NFC for Google Wallet. It won't really affect us when it is merged into CM7. ICS is expected to be Android 4.0, but it could be 3.5 if Google decides.
There is a kernel that goes over 800Mhz, but anything over 768Mhz can be unstable on some phones. I tried it and there were no real performance gains, but battery life was a lot worse. Performance was actually worse at the highest CPU clock, in my experience. Just stick with 768Mhz. It's stable and chances are that you can get even better performance at a lower clock. I get better battery and performance at 633Mhz. It all depends on each unique phone.

I can confirm that the Godmode kernel was able to push some phones, such as mine, past 800Mhz. Although I had a faster processor speed, my battery would drain incredibly fast as well as overheat. Even though I never hit a bootloop with the kernel, the battery life, overheating, and loss of performance kept me away. Sacrificing too much for having a faster processor speed. Normally I overclock to about 729Mhz and have great battery life, speed and performance in conjunction with a min of 19Mhz and a smartass governor.

Yup, I'm at 806 - 19 ondemand while posting this and I can already feel it slowing down a little. 729 - 19 on demand is my best setup. I've tested a lot with trying higher setups than that but so far 729 seems to be the best for battery life and performance on every rom I've ever tried

Correct me if I'm wrong, but from what I've noticed is that newer Hero's that were sold with Eclair as opposed to the original Donut, when I bought mine, are not able to reach those higher processor speeds past 691Mhz.

i bought mine at radio shack back in september and it was still on 1.5 and ive never been able to get over 768mhz without it freezing and bootlooping its different with every hero.
i stay at 352-691 ondemand and thats plenty fast for me
Mine was running 1.5 also and it will run fine at 768 but battery life suffers so I usually run at 352/710 and battery and performance are good (depends on rom kernel)
Where can I get the godmode kernel ....

Hey rubyknight,
just wondering why 19? Ive seen people do that but can the processor really ever do anything at 19? if so, doesnt it affect stuff like wake. Im trying it now just to see for myself. Ive been playing with a really high min value between 480 and 576 with the high at 748 and it actually doesnt only seems to affect battery life a little, both on the .29 and .35 kernels on jaybobs roms and on OMFGB.
Thanks

so update, ive run it at 19/768 on demand all day and after 11hrs 13 min its at 60% thats not bad for my phone! and there was almost no performance difference. Just the slightest UI lag... this is on jaybobs 7/8 with the .29 kernel, with background data off. And my regular usage which is not a lot. but for me its good. i wish I had tried it ages ago.

Which of the current 2.3 ROMs is considered the fastest/most responsive? Or which ROM would be considered the fastest based on the mods & tweaks used by the developers? I'm not to versed in the technical side of things to discern which tweaks/mods/kernels/etc give way to the most stability, speed, and response and would like the community's opinions on the matter.
Probably CM7, I just started using it and there is never any lag. I haven't even OC'd it yet. This also comes with the price of having to live off a wall charger though.

If you mean fastest in clock speeds, then thats a balance betwen rawr clock and how much battery life you can get out of it. Keep in mind these phones clock easily 1.2ghz-1.3ghz no issues past that you need to increase the voltage. So you can in theory get 1.6ghz-1.8ghz but you will live next to a charger. If you mean fastest on how it feels Id have to say Continuum moved awesome few months back (haven't used it in a while) Atomic Fusion if the ext4 version comes out. But there you should just test them out.
On a side not if you want to OC your phone and not have to pay for the oc app, then Id suggest you stick to I9000 ports or AOSP's like CM7 or MIUI. Native roms like Cognition 5, Atomic Fusion and Nuclear Fusion need Tegrak for OC/UV.
Which of the I9000s seem to run the fastest/smoothest? I've been looking at Dlev and Darky but how does Apex/Symply GS II/Mosaic/Sensation compare?

I actually read in the Glitch kernel thread that when overclocking, higher voltages doesn't always mean more stability. I'm OC'd at 1.5ghz right now really stable and I was UV'd at -50mv but I just dropped it to -75mv to see if its stable there. I'll keep dropping it till I have issues.
Oh yeah, and CM7's battery life has got WAY better over time, so I'm not having to worry about charging all the time either.

From my experience to maintain a stable phone i over volt the "step" that's overclocked, and then undervolt the other "steps". Im by no means a expert nor is there a full proof way to do it. Each phone kinda reacts differently on the overclocking past 1.2-1.3ghz.
Which of the I9000 roms should theoretically run faster due to the tweaks/mods used by the developers without the need to overclock?
There if no need to overclock for daily use. Only if you are playing very demanding games. And only during those games.
As for fastest rom....have a search this question gets asked a lot with always the same answer and result:
There is no best rom, all phones are different as well as tastes, what's best for me on my device may not be on yours. Flash and try a few and make you own decision...
CM7 is fastest but Display and Sound quality is not as good as stock ROM .
Before school started for me and i couldnt access a charger when i wanted to, i used MIUI at a stable 1.6 GHz ALL of the time with odemand govenor and i got like 18 hours with moderate use, on Glitch V12! And you dont need to overvolt for higher speeds i have tested it and its better to undervolt higher clocks, i get better battery and performance!
