Hey, I'm a new to overclocking and was wondering what you guys have found to be the best settings on your Transformers using setCPU?
What are your settings for:
Fastest...
Best battery life but still usable...
Which kernel are you using? I'm using Netformer 1.5 and I just have it overclocked to 1.2Ghz. Honestly though, I don't really notice much of a difference in performance or battery life compared to 1Ghz
yeah I've been playing around with Netformer too and I don't notice much either way either. Thanks for the input.

Hey all just a quick question, obviously with the 1.8 OC on the Inspire this thing is blazing. But what is the battery life like at these OC's or even the voltage differences between stock 1 ghz 1.3 and say 1.8? I really just don't want to get the phone and OC it to keep it fast/smooth but have my battery last like 5 hours. So any insight about how much OCing affects battery life would be appreciated. Thanks!

well overclocking will drain your battery down faster. I would install setcpu from the market and set you clock speeds really low with the screen is off. This will help save battery when the phone is not in use.
This is a question for those who have overclocked their Xoom. How much is overclocking to 1.5Ghz affecting battery life?
Overclocking would be the only reason I would root right now, and I am trying to make up my mind on whether to do it.
My battery life is better after using setcpu to overclock. The reason is that the tegra2 chipset scales the performance based on whether it's needed(IE, when you're using your xoom) with setCPU you are extending the top end of how fast the CPU can go. The clever bit is you can also tell your xoom to slow itself down and go very efficient when the screen is off or if the chipset gets too hot (which it never has). If you do go for it I recommend using setcpu using interactive scaling (prioritising the user interface) and whack the max speed up to 1500 and the min speed down to 217 mhz
I wouldn't recommend setting screen-off profiles at the moment. It seems to lead to some strange issues once in a while.
That said, because you're only going to 1.5 GHz when needed, battery life doesn't really suffer. Additionally, at least in my usage, my screen uses ~70-85% of my battery. This is even during heaving gaming, where the Tegra 2 really has to work hard.
I wouldn't worry about its effects, personally.

All CPUs do this, not just Tegras.
Re scaling, never said otherwise I've never had a problem with screen off profile. Maybe just lucky
I know overclocking is all the rage for more performance. I myself would prefer the gains of overclocking (probably wouldn't be 1.7 ghz atm since that is the performance based kernal, but 1.5 ghz might be doable) with a combination of undervolting for longer battery life.
I know when I was considering a viewsonic gtablet, that most of the kernals that overclocked also undervolted at the same time (how much depended on the kernal and how much of an overclock too).
Advantages to overclocking are pretty obvious, more performance. Undervolting makes the processor (this case SOI) run off of less power, thus more battery life (can be significant if undervolted enough) and less heat, which translates into a tablet that potential has a longer life (heat overtime wears away at life of SOI/processors and sometimes other components), plus much lower risk than overclocking. I undervolt all my laptops, I mostly get my laptop with 3 hour battery life to 3 hr 30min or even 3 hr 45 min on a moderate undervolt. A little undervolting could take this tablet from 8-9 hours to possible 11-12 hours of battery life (plus a little overclock included will add some performance too).
Do any of the present kernals out there try this? If not, I would like to make a request for such a kernal.
Undervolting might cause the TP to be unstable and crash.

it would need to be done in small increments just like overclocking. Same methods are used undervolting as you would overclock. Yes they could both cause instability, if you double the clock speed or cut the voltage in half, it takes time to know the limit of the SOI by using small increments.
You will need to your favorite custom kernel and adjust the volts yourself using Govnah.
But then I also was reading on forums on webosbuzz and you can have screen wake issues to with undervolting

Really? If that is true, I wonder how undervolting would cause that.
The webos-internals-testing kernels include initial experiments with undervolting.
im currently on icbinb kh1 with the gingerbread enhancers. im interested in overclocking but i want better battery life. the undervolt settings in the gingerbread enhancer has worked great for me. does anybody have a setup that they feels increases performance while offering better battery?
the best solution is factory clock settings. If you want performance, you're going to sacrifice battery. If you want battery, you're going to sacrifice performance. Think of it as a sliding scale.
thats not necessarily true. i overclock at 1.3 on my phone and it lasts about 3 days with normal use.
if you have bali uv installed, its already undervolted, so you can overclock at higher frequencies. with the right things in place, there is no big negative tradeoff.
look in the icbinb thread for anyone else overclocking. i no longer undervolt using the given values cause it caused freezing. i use stock with a level 0 of 1.3. works great. battery lasts forever. no complaints.

I use the same settings on ICBINB but on 1.3 I only get about 13-15 hours of battery life without charging. Guess its just different for each person based on usage.
i like 1.2 uv fast and pretty good on life.
frequency=1200000, 800000, 400000, 200000, 100000
core_voltage=1230, 1080, 1005, 905, 855
int_voltage=1090, 1050, 1000, 980, 950
scaling_governor=ondemand
thanks i just wanted people to chime in with setting that worked for them, try a couple out
I know there are some threads out there that have addressed this topic, but none are for the HOX at least that I can find
I am trying to find out if there is an empirical data that points to the best combo of Kernal/ROM for batter life?
As of right now, I am using RageXL 1.0.3 with the Elemental 6.7 kernal. I have it overclocked to 1.7gHz with the standard voltages. I also ran the Supercharger script in the ROM
I have used VenonXL in the past and it seemed to kick a$$ but with the stock kernal
Also, I understand that there are a myriad of settings that can affect battery/ performance and makes this question very tricky to answer. I am looking sort of the general consensus of the situation
Pretty much all sense ROMs have good battery life. You can clock it lower for better battery.

This.
My best battery was with elemental 6.7, max clock was 1.5 and min was 192 with intellidemand governor and ROW scheduler. Also, I undervolt to 800. Be careful with voltage though, most phones can't handle it.

That's the first thing I noticed about Cyanogenmod. Much lower battery life. I installed SetCPU - will that fight Elemental 6.7's clock settings?
