Overclocking - pros & cons?

Yes, I FINALLY did it!!! I overclocked my G2X. I would appreciate if anyone could share their experiences with o.c. pros and cons... Should I retreat or stay where I am? Please some feed back!

Over 1300 seems to cause trouble on mine.

i dont think oc'ing is really that necessary with a phone this fast but if u must i wouldn't go above 1.3 (just seems unstable above that). I think the "Pros" come from being able to underclock. Setting up profiles for uc'ing when screen is off or as battery level drops etc really prolongs the life of the battery (at least in my case)
On my OG droid that came limited at 550 mhz, ya, oc'ing was def necessary but I cant really think of any "Pros" for oc'ing this phone.
each phone is different though so play around and you'll find a combination that works great for your phone, good luck

Well... you can get some serious bench scores... This thing rocks the Mandelbrot multithread test in smartbench 2011 at 1.5 ghz. Other than that it helps with games.

What about the CPU not having enough cooling and frying the CPU over time. I presume its just like Desktop overclocking but without all the extra cooling you can add to make it safe for the hardware.

But what i really want to know is if oc could damage the phone. After all if there is that danger it's noy worth it...

In all honesty I used to be really into benchmark scores and OCing the heck out of my phone and under volting it in the process but that led to many battery pulls ect. What I've noticed is just keep it at stock and mild uving seems to be the best for me its stable decently fast just 2 cents though

Overclocking a cpu is the same as on a pc, only a bit more dangerous on a phone. (This phone already has overheating problems running at stock speeds ) On a computer, people pay a premium for parts that are easily overclocked, and have either very good fans/heatsinks or a liquid cooling rig.
Overclocking is dangerous, especially because not all chips are going to be made equal, even if they come off the same production line. These chips are designed to run at a certain voltage, and certain clock speed. As far as real world use, (NOT benchmarks. Sure, they look pretty and all, but benchmarks are never very accurate.)
Sure, you might get 2-3 more fps on your games, but is that worth the risk of shortening the life of your chip/phone?
(And just so you know, I've been building/overclocking pc's for years, but I also understand what you need to do to keep it stable, and it's *all about cooling*.)
If you're not convinced, try this. Don't overclock your phone, and use it for a few days. Tell me honestly that you really notice a real-usable difference with the chip overclocked or not. (Games set aside, but like I said, getting a couple extra fps on a game to me isn't worth the risk without a proper cooling setup)
For those of you that really don't understand what you're doing to your chips when you overclock, I'd suggest doing some reading about it. A good place to start would be here: http://en.wikipedia.org/wiki/Overclocking

So you think using fauxs kernel is not safe or reduces the life of the chip? I just flashed it and didnt oc or uv further then fauxs default settings...

I'm not saying it's for sure, I'm saying there's a chance.
Plus keep in mind that these kernels have other really nice additions besides overclocking and undervolting. I'm using faux's stock voltage kernel ext4, and leaving it at stock settings, and it really works great.
I just posted this up because I see a lot of people more interested in quadrant scores (which to me are pretty useless) than stability of their phones. If you do overclock, and it works for you, more power to you. I just want to inform people. I'd HIGHLY suggest if you aren't sure, read that wiki article, it's a great place to start. (not all information is there, but it gives a very good general idea on how and what overclocking is.)

Thanks! i always like reading knowledgeable and informative posts!

OK, you definitely convinced me.... I have also faux (let me tell you exactly - Kernel Version 2.6.32.9 FR Faux 123-v0.03) on EagleBlood 1.05. Could you please tell me what I need to do set up in order to be safe? Thanks!

I'd just go to faux's thread in the development section (his froyo thread, not the cm7 one, since you're using eagleblood), and download his stock voltage kernel. (It's in the first post.) He's on .04 now, by the way.
Then reboot into recovery, and flash the file you downloaded. It'll overwrite your current kernel and modules with the new one, then reboot.

And a lot of times the kernel will be credited to the developer. So if you see "faux's kernel" people are referring to kernels by faux123. Trinity kernels were developed by morfic. If you are having a hard time finding a specific one, look at the top left to see who started the thread and sometimes that will help find it. Does that make sense? I had to pull an overnight at work so I am a little loopy....

[Q] Best Kernel for battery life/stability

Hi I am flashing this phone for a friend and I come from the Samsung Captivate so its fairly similar. Only question I have and I hope someone can help without flaming me is which Kernel would you suggest? Im going with Infused 1.5.2 as the rom and I am just curious what pairs with that best? Thanks in advance.

if you're one of those "set it and forget it" types... i was incredibly pleased with the latest release of gtg's infusion 1.5.2 rom/kernel combo. very responsive, smooth and snappy. by far my favorite of all his releases to date for this phone.
if you're the type that likes to do a bit of fiddling for an ultimately rewarding end result, i recommend installing the above mentioned rom with bedwa's OC/UV kernel. i've had nothing but a smooth and stable experience with the two paired together. nothing but good things to say about both of these. having voodoo lagfix alone makes a huge difference. when you combine that with overclocking you get a device that feels much more awake and ready to perform. undervoltage allows you to use less battery power, even though the cpu is running at a higher frequency. really, makes a HUGE difference. cannot express how pleased i am with these two running together.
*i might also add that i've never installed any of the other roms. i have tried the defuse kernel with BLN was introduced(it has since been removed due to buggy issues).

cool man. no problem. infused rom makes a world of difference in itself.

I've had the best battery life and stability on Infusion 1.5.0
Overclocked to 1.6, with the right undervolting i lost 3% battery over night (9+ hours)
I tried the 1.8 infusion but "OnDemand" stops working and thats my favorite setting so I went back to 1.5.0

I never had good luck with ondemand, along with most other users. Ondemand always FC'd on me

BLN Pro

I'm not really sure what forum to add this to, so please excuse if its on the wrong one. I would like to install the BLN app, but I dont know which kernel to use, or if its even supported. I found a thread here that showed an infuse kernel, but it looked like it made a whole bunch of changes, all i want is to be able to use the bln app if possible. can anyone point me in the right direction, or know if this app can even be used with the infuse? thanks!

I THINK you can use BLN with the froyo roms but it currently does not work in any GB ROM. I'm still relatively new to infuse and never used any froyo ROM besides stock. I know for certain its a no-go in GB. Causes too many instability issues. I would check bedwa's earlier infuse kernel thread. He seems to be the go-to Guy for kernels. The thread mentions its for froyo in the title and should say if BLN is supported in the first post.
BTW, I'm not aware of any kernel that turns on just BLN.

BLN is in Defuse 1.5 and the latest Infusion Froyo releases, HOWEVER:
It's flaky as hell on Froyo and for some people may have caused system stability issues.
Every attempt at implementing it in Gingerbread led to unstable devices - Bozo or another kernel dev might take a crack at it again sometime, but since it's proven to be such a pain it's a low priority while there are bigger fish to fry.
I can tell you I won't be putting any effort into it - the feature is just not worth enough to me to justify the level of effort required to get it to work in a stable manner.

Yeah I'm back on froyo and using the infusion kernel and the bln gets really annoying. Especially since it won't disable for me.

why is it so flakey?? it works great on my galaxy s i9000t with speedmod kernel in froyo? is it just that the developers of the bln enabled kernels have not taken the time to integrate it correctly?

We have a different touchkey controller chip - it's annoying. Every attempt to implement BLN for this chipset has resulted in:
1) Weird flaky timing - this is due to the architecture of the touchkey controller driver in Froyo, it's very BLN-unfriendly
2) Random reboots - trying to add BLN into the Gingerbread version of the touchkey controller driver causes a lot of potential nasty race conditions involving entering/exiting suspend. Every time LinuxBozo found a bug and squashed it, another bug surfaced. After a week of messing with it, he ripped it out and we're focusing on other higher-priority stuff like Bluetooth for CM7.

Yeah I switched back to the community kernel from the infusion kernel on infused 1.6. The lights blinking were totally random and there wasn't even a notification. When I did have a notification the lights would just stay on. And like I said, this was with bln friggin disabled! Lol. I've never cared for the feature to begin with. Not that hard for me to push the power button and see if I have something.

Best kernel to keep things simple, stable

I'm really very happy with my Nexus S 4G. It's unlocked and rooted, but otherwise pure stock and I really like it that way.
Coming from the Hero it's a pleasure to have a phone that doesn't require heavy modification to make it perform properly. Still, I miss the thrill of flashing ROM's and kernels.
I would like to try a kernel...mainly to simply o/c a bit, but I don't want it to suffer stable and reliable operation. I recall with the Hero, some of the kernels would adversely affect things like the GPS, making it something I couldn't rely on.
So my question: what kernel can I use that is uncapped, but will otherwise be as close to stock as possible?
Thanks for your thoughts!

Kernels are pretty different over here. I don't even know what's closest to stock. They pretty much all have mods in them. Matr1x kernel is pretty popular. You may have to up the voltage for it if you oc to 14xx. 1200 seemed pretty stable to me with default voltages. Currently franco kernel is pretty popular. You can't oc it, but it seems pretty snappy without oc. GLaDOS is also being used a bit but i've read some mixed reviews and for me at least it did seem a little lagging at times for the short period I ran it. I tried Trinity kernel when I first moved over from the hero and it seemed kind of flaky though it's possible that could have been due to the kang I was running. There are a few others out there. Cm7 kernel has a lot of the same mods cooked in though it's likely not the latest updates. You will see a lot of mention of BLN and Voodoo. There are apps on the market for those features and there's an app nstools that has some kernel config settings you can adjust depending on kernel. Mainly just try to read a lot. Most of the roms and kernels haven't given me any major issues beyond the random reboot, which coming from the hero, just means "normal" lol.

Once you flash you can't stop O_O that my experience i'll direct you to Peteralfonso's kernel on his website here

Searching the forums would help you more than anything. You will get more info by searching, rather waiting people to reply here. These questions are asked on daily basis. And get the same replies everyday. I don't sound to be mean but seriously there is more info than you can get by starting another thread, only thing is you need to dig the info.

I have tried a few different roms and kernels and for once cm7 runs perfect for me w the supplied kernel. No reboots. Has been stable at 1440 performance for testing but I usually leave it at 1000 on demand.

Yeah they all have this blinking light crap in it now by default which I hate, and the lights turn off and I don't like that either. I want the light on when I'm using the phone and off when I'm not, not the other way around!

I like the bln mod, but I do not like the one that turns off the backlights when using the phone. It's just easier to use the buttons imo and gives a quicker visual reference for everything. Otherwise I mostly am left wondering what is up with all the black space.

I hear you on that, and spent a lot of time reading comments and concerns and problems about the various kernels available. They all seem to pretty much be experimental, with various idiosyncratic problems and lots of bells and whistles such as aforementioned BLN, Voodoo, deep idle, etc.
I thought maybe I was missing something in my search for a kernel that would allow o/c, but not have the stability concerns of a the feature-rich, highly customizable kernels.

I think the Matr1x kernel will be your best option, u can OC it till 1400mhz, what I don't recommend to do, but at 1200/1300mhz its pretty stable.
It also got many options like BLN, BLX, Live OC, touch wake, etc.
But if you don't want them, why you just don't use 'em?
Like just flash the kernel and keep it like it is, and maybe do some overclocking.

wanna stable ? stock kernel
basically , there is no kernel more stable then stock ...

franciscofranco's kernel (link) works best for me. It's fast (no lags even without OC, I'm running at stock 1000 MHz), reliable (I've been using it for at least month and I haven't got any random reboots or application hangs) and battery efficient (thanks to deep idle and other tweaks).

Screen sensitivity adjust in clockworkmod recovery will cause MAJOR lag

I discovered that if I adjust my screen sensitivity under clockwork mod recovery from "default" to "sensitive2" it will cause my captivate to seriously lag. It makes almost everything go hay wire. This is just a resource for anybody else who might have stumbled onto a lagging problem.
I am using the corn 7.06 kernel(thanks mtcarey) and the legend 3.7 ICS ROM(thanks crt60), I have my governor as smartassv2 and my I/O scheduler as SIO. My LMK is at 70mb, instead of 48 default (this will probably change depending on stability).
My captivate has run smoother than it ever has on these settings, with lots of the bloat removed as well.

Can anybody else confirm this?
Corn 7.06 has CWM v5.1.0.7

Yes, I don't think it's lag, but rather that the sensitivity is just messed up. I would check the corn thread, as others may have had this reported.

Are you interested in going into clockwork mod to try and see if you can re create the issue? I'm curious to know if it's just my phone + tweaks/setup...
I can agree, at the moment I want a stable phone, I use my phone too often for school and stuff to be worrying about errors, besides finals week is next week for me so i need less distractions... I'll wait till I see a smaller bug's list on the ICS rom threads. I want to try it out, but i'm gonna wait.

I don't seem to be getting any lag after setting that tweak. I also have my LMK set at 78, but my governor is set to ondemandb because I found that smartassv2 would be slow to wake up from sleep and ramp up the processor.

Hmmm.. That's interesting.. I wonder what was causing my issue then. I'll try some of the other sensitivity settings later today when i have more free time.
I also tried changing the init.rc tweaks to the system corps tweaks and i got a similar lag which was immediately fixed by switching to no tweaks... I wonder what I'm missing here... If i don't have, any of these tweaks on my captivate is super smooth
Thanks for all your help!
At the moment i seem to be good at finding problems... As time goes i should get better at fixing them on my own and then i wont post silly questions.
Again thanks.

I think those tweaks in tandem with screen sensitivity may be doing something. I had maladroit.tweaks on when this happened
Sent from my CM9 ICS i897 Captivate

I wasn't using both at the same time, i used them separately. I'm just going leave it be for awhile i think. I'm so happy that it's running so smooth compared to before it was rooted and de bloated.
I'm probably just gonna wait till ice cream sandwich is more stable, or i have a new phone, then I'll mess with that.
Maybe I'll just wait till the galaxy S III. Anybody else excited for the possibilities of this new phone coming up? I guess that would be something for the questions forum though.
If you've got the time, can anybody give a brief description of what these init.rc tweaks are supposed to do as a whole? I read the system changes of each in cwm, but I'm not sure exactly what they do. It's fine if you don't answer, i know it would be a long post, i just wasn't able to find an explanation. I'll thank you if you do give a good explanation though.

No, i just now found out about thunderbolt...
I'm pretty stock, i'm on RFS, legend 3.7, corn 7.06, the only tweaks I've kept were the LMK and changing the I/O scheduler and governor.
Thanks again for all your input, i'll hit the thanks button for you guys. You're great for helping a beginner learn for the first time.

I have Thunderbolt tweaks in my ICS ROM. Not sure if they help. AOKP and kernel developers added their own support of these tweaks thru ROMControl, NSTools and Semaphore app. SQLite rebuilder is nice I guess. Zipalign is useless - all apps already zipaligned.
