Just wondering if its bad to set the CPU to run at 1500 MHz all the time on the Xperia S? I am using CPU Master to set it to performance profile.
I don't think it's potentially harmful for your device.
However, it will consume much more of its battery, resulting in decreased battery life.
Possibly it will also generate more heat.
Besides, it is completely unnecessary to do so. Your phone will manage the speed depending on the required resources.
Hope this helps.

First, you crack the bootloader.
When you've done that, I'm guessing you allready figured out how to OC the CPU

For now just use the overclock widget. set top two settings as high as you want up to 998 click on off screen frequency. set between 246 and next number you choose. set at boot save. define settings at what mhz you like and experiment. do not run on screen and off screen freq at max. i have had my battery sweating and even plugged in all day and not gained a single % of charge. until boot loader is cracked.... this is all you can do.

Although it's impossible today because of bootloader, note it's always dangerous and not great to overclock embedded cpus.
You can't overclock a lot, as you have a battery (X10 works about 5-10 hours with full speed - 998MHz), and the CPU only has passive elements to cool. Overclock can damage your CPU and your motherboard, stress all elements and low your battery life (battery charge and cycle of charge). (Even there's a self shutdown when too hot)
You can get an idea of overclock on Nexus forum, as we have the same CPU (Snapdragon 8250) - I saw overclock up to 1300 MHz, but it's really not looking safe to me
Thanx everyone..

Depends also on the voltage (as long as your voltage isn't increasing as you overclock, it isn't really that harmful as long as you watch the heat), and what you have your underclock speed set to with screen off (as this can in some sense reverse some of the possible "damage")...
I had my htc hero overclocked to 710 with the screen on, and underclocked 176 with the screen off and it ran a lot better.
I digress, I see no purpose in doing so when you already have a 1ghz processor that is super fast. I only really see a point in overclocking if the possible benefit is greater than the possible harm, and in this circumstance, I really don't think you would see that much benefit.

I have seen considearable difference when maxed out. however the dangers are high of overheat. ive done it once and onetime only. kept on and off screen at 998 and hat it plugged in all day with out a single gain of battery. it was like on life support and was hot enough the phone was sweating even when sitting next to a fan blowing on it constantly.:-( since then i have made adjustments to run between 700 and 998mhz on screen and min 246 and 400mhz when screen off.
if looking for better performance without the overclock and good drain of battery, download and install sysctl from market and follow settings below.

Not in all instances. Depends on the quality of the chip. Lot of chips are capable of handling higher speeds and temps but are set lower quality assurance.
For instance, I've got a NookColor that has base CPU set at 800MHz and is now overclockable to 1.2GHz
We'll have to do stress tests on some to see what they're capable of.

Agreed.
My Motorola Defy has a Omap3630 that comes at 800MHz,stock but can be easily overclocked to 1.3GHz without a sweat.
Just depends on the chip's capacity of "Stress".

As I understand solution for "998 MHz with screen on" bug is found: http://forum.xda-developers.com/showthread.php?t=1225411&page=17#post16944722
We need to replace only one governor.
I don't want to play with different ROMs and kernels and I'm looking for simplest solution.
Is it possible to compile it as a module ("ondemand_mod" for ex.) and add it to stock ROM?
Or any other (simple) way?
Wrong section ...

Exactly, this is the right section for such request.
However, I can't help but wonder: is this really a "problem"?
No offence to anyone, but I find that the phone is very snappy
when on max frequency... The big problem for me, would be if it
didn't go into Deep Sleep immediately after turning the screen off
and stayed at min frequency for an extended period.
When the screen is on (aka using the phone) I'd like it to be as FAST
as possible. That's the reason I use the minmax governor.
Anyway, again, I don't mean to argue with anyone, I am just
presenting my point of view.

Yes, it's really problem.
Higher frequency - higher power consumption. Moreover - with higher frequency CPU used with higher voltage so consumption is even more higher. So at 998 MHz CPU eats about 5 times more battery than on 246MHz.
With properly tuned governor I don't feel any real lags or slowdowns.
And, when screen is on CPU load is usually is lower than 20% at full frequency. So I don't want to waste my battery.
As I see it's possible to compile and use governor as module.
Could someone compile it? And assemble as xRecovery package?
Or point me where to read about compiling for arm, where to get tools and so on...

The thing is, on 245 MHz, you can't get any kind of decent performance.
Try this: set the minimum and maximum CPU frequency with SetCPU to 245 and attempt to use the phone normally.
Also, you might be right about voltage, but if the CPU is forced to work on lower freqs when it actually needs higher, there's definitely stress and increased battery consumption.
My phone lasts for more than 24 hours and it's always at max frequency when the screen is on. No lag, no freezes, no drain.
I do agree that the ondemand governor might not function as expected but I fail to experience the actual problem. That might be just me though.

There is no need to work on 245MHz as proper governor rise frequency automatically when it's necessary.
And really no stress for CPU to work an low frequency at full load. Moreover - CPU will consume more power at 500Mhz with 45% load than at 250Mhz with 95% load.
Sometime I use phone for navigation - long time with screen on and very low load. In this scenario battery drains very fast.
And last one - I like to have everything working properly. In case that I'll really need high frequency all the time I'll use other governor. I just want to have a choice.
I need a simple solotion for this too..I use z kernel and I found that Thego2s kernel fixed this problem..I was going to flash that kernel but think that has a bug and stoucks on logo ..can some one sayas a simple way?
Yes, I think a lot of people would prefer to use just small and simple fixes rather than replacing the whole kernel with a lot of nice but (personally) unnecessary features.
I am waiting for developers to release a fix for this problam
What are the best settings to have you phone's CPU speed set at? I'm looking for both good performance and good battery. Also I am using the default overclocker, what is the best one? Thank you guys for your time.

I use SMARTASS as my CPU speed governor and I set my CPU to 480-748 MHz, seems pretty stable for me.

Overclocking values differ from phone to phone. Test it out with different values and use the one which is stable for you.
This was just discussed in the IHO technical-discussion thread, as a matter of fact.
My phone is stable for most stuff at 806 MHz, but sometimes the camera will cause a freeze/reboot. So I run at a 786 MHz max. Your phone will be different; this has to do with minute physical differences between individual chips.
The thing to keep in mind when overclocking is that the processor in our phone (unlike those of many other phones) does not make use of dynamic voltage scaling. There are only two voltage levels: a lower one if the phone is running at or below (or is it just below? correct me if I'm wrong, guys) 480 MHz, and a higher one if the phone is running above. So below 480 MHz, the system will give the processor a certain amount of voltage (period), and above, the processor will get a certain higher amount of voltage (period).
Because of that, the tests that have been done indicate that 806 MHz is the sweet spot for battery efficiency when the phone is in use--and the closer you get to 806, the better. Thus, I've had the following settings for quite some time:
786 MHz min
786 MHz max
Performance governor
which has treated me pretty well. On a day of light to moderate use, I'd end up with 65-75% battery left (occasionally more like 80%), depending on cell signal where I am et al. And it gives me probably the best performance I'm gonna get out of this phone.
However, I very recently decided to change the minimum to below that 480 MHz threshold and see what a lower voltage when idling would do for my battery life. My current settings are:
320 MHz min (may change to 480)
786 MHz max
Smart*** governor
There is actually a noticeable performance decrease when I first wake the phone up, so I may switch governors as well. In any case, I've had those settings for only one full day now, but for that one day the battery life was noticeably better. I'll post an update when I've had a few more days to test.
As always, it's difficult to quantify battery life in a reliable/rigorous manner (much less a universally applicable one), so YMMV.
I've never OC'd any of my phones before but was keen to try it on the Galaxy Europa as the 600MHz CPU seems a bit weedy at times. What settings would people recommend? Ideally I would like good on-demand performance, good battery life and no frying of the CPU
Thanks
I not guaranted for the results but you can try to raise to 710. I tryeid and its work for me on any of cyanogen roms.
I use smartassV2 with a frequencies range of 122-480 Mhz. For me a longer battery life it's more important than waiting a second! And if I need to play something hard I set max to an upper freq..
my 2 cent..

As long as you can have means to cool it! Im not saying its ok but it will decrease the lifespan of your device substancially, especially if you just leave it jacked up all the way
You may switch CPU governor to performance. Not necessary means it will use max. freq. all the time, use will give smooth performance for games.
