Hi, i have just flashed the new HyperDroid v5.2.21 (Full wipe) and i wanted to know if i can overclock my SGS2 from 1.2ghz to 1.5ghz, if so how do i go about it?
Do i need to change the current kernel (XWL1)?
P.S ive heard its stable, but does it drain the battery?
Thanks XDA Community
Hello there. Yep you can overclock but you need a kernel that supports it. [url="http://gokhanmoral.com]SiyahKernel[/url] is a good choice. With that, use the Voltage Control app from the market.
However I know nothing about battery draining or stability... dualcore 1.2GHz mobile processor is more than enough for me, and the phone can get pretty hot under maximum load, same with the MALI GPU which can be overclocked to 400MHz (but since it has 4 cores and the phone has no active heatsinks it could get risky...)

Yes you can overclock and you can stick with the kernel that comes with Hyperdroid. I am currently Overclocking 1.6ghz max and 200 min. Not touching voltages though. Use No-Frills app to set it up. My advice though to you no point in overclocking as 1.2ghz is good enough as it is..And the kernel you are on is good enough...It is stable depending what voltage frequencies you use..I say leave it as they are. And like i said download No-Frills from the market..Set your clock speeds and that should be it..Choose a governor and off you go

No-Frills ? AndroidMeda Developers recommend Voltage Control (and I personally like it much more than No-Frills, too) with their kernel.
+ Here is a small guide : http://forum.xda-developers.com/showthread.php?t=1036020 how to test your OC Settings, I use it when I am testing new voltages.
Thanks for the replies i will try out the no-frills app and see what happens. What would you say is the best governor to use? and wouldnt you recommend going over 200min?

Pongster uses No-Frills. The rest of the team uses Voltage Control. And to avoid any freezes or random reboots leave the voltage settings as they are till you get to grips with the overclocking. Hence why i suggested No-Frills as currently Voltage Control for me kept on reverting back to stock frequencies..And yes there is a way round it but it is to much of an effort

I am currently using ondemand and Sio as scheduler. You can not go wrong with that. Like i said..choose a governor choose a scheduler and let them do the work...I also do recommend Voltage control but No-frills is simple and does the job for you. And no i would recommend either go to 100min or stick with 200...I am currently on 1.6max and 200 min

im running the extreme1.92x kernel oc'd at 1.4 but not sure about the best setup to save battery. i made one profile for charging i put in on max. not sure what to do with the advanced tab settings.
Profiles are really dependent on the user and their needs. The one piece of advice I can give you is to make sure you have a profile set up in case your phone starts to over heat. An OC'ed phone maxed during a charge may get quite toasty.
any suggestions?
Imo dont o/c. Let the kernel operate the way it is setup. O/c cause reboots, phone heating up, and freezes.

I'm running Adrynalyne's 4.4.7 kernel and use the following and get really good battery life with no overheating and no lag. I don't do a screen of profile because the governor seems to handle that pretty well.
Normal 1024 max 245 min-Smartass governor
Profiles:

Does that actually work?
I thought you had to choose a default governor and setup profiles accordingly.
I didn't know you could setup profiles with a governor that wasn't active or chosen on boot.
the thunderbolt is so fast already theres really no need to over clock. i left it at stock for normal, toned down to 768 when <30% battery and down to 368 when screen off. its a little slow for about half a second when waking up but the battery life is amazing. i can make it through a whole day without charging with moderate use. also running ziggys bfs kernel on virusrom and that added a ton of speed. way better than overclocking that drains your battery
im not asking about overclocking or profiles, just want to know about advanced settings. everything is set to default -1.

What Rom are you using?
Go to settings, menu, wireless networks, mobile networks and uncheck the third box. No need to have mobile data always on for most peeps . You'll still have 4G n everything, but gain a good 1-2 maybe more hrs (depending on use, kernels, governor settings, and I/O scheduling. I personally am running BAMF 1.6.2 with adryns 4.4.7 kernel, no set CPU, using tool box for that at 245mhz min - 1.024GHz max with ondemand governor and most importantly SIO Scheduler.

errr. i thought i posted this in the general section?? seriously i thought i did..
on the other note. smartassv2 seems to be used by many. i shall give it a try
So i tested out the recommended settings from you guys
XPERIA MINI . ST15 . antutu benchmark scores . over clocked my cpu to 1516 with voltage control.
my current set up interactivex/sio (score 3951)
savagedzen/sio (score 3911)
smartassv2/noop (score 3991)
smartassv2/deadline (score 3953 )
lagfree/vr (score 3953)
not sure whether antutu is best app to test out but yeah.. lol btr than nth i guess
1.5GHz is not the best frequency for the Mini - it causes the CPU to freeze frequently. Even 1.4GHz frequency is not the best. 1,3GHz and interactive governor is the optimum for my Mini - fast, responsive, no lag, no freezing, 2 days of battery life.

seriously watch out with OC that high.
You can easily fry your mainboard/CPU and than it's goodby mini. Better have a mini that work's than having a fried mini...
at least watch the temperature.
just my 2 cents...

hey man thanks. i didnt really know what freq to set it to.. what would you recommend. the guy above ur post said 1.3 is good. agree?
First of all, ask yourself do you REALLY need OC. Or are you just doing it because you can
I personally think the mini is sufficiently fast on it's own?
But if you must OC then install a temperature monitoring app and let it warn you when the phone gets exceedingly hot.
Because if you play a game while OC-ed, the temp might jump real fast real high.
And by the time you figure that, the phone could fry.
I definitely wouldn't go over 1.5GHz. Even that's real high. 1.3GHz seems to be ok though
I run 1.8 with Brazilianwaw & bfq 24/7

btw how do we know that our phones are overheating?? mine is usually around 28-35 on normal usage but when gaming it goes to around 40++ is that ok?

There is no safe stuff.
Overclocking is dangerous in every damn way.
No one wants to brick their phone, they don't play with OC. Besides, performance boost is quite small, pointless to waste the juice.

O-o that's very odd...which roms have you used exactly? Have you stayed mostly with froyo roms? GB roms or ICS?
Also- what kind of settings do you use? Governors and schedulers? frequencies? Do you OC or UV? Etc. Etc.

I've stayed mostly with the ICS roms.
No governors/schedulers whatever...nothing else on top of the ROM.
ICZen with sub-Zero's kernel was always my favorite ICS build, but you're going to have to accept some kinks when you're running ROM that's been ported over for a device that had official support stop at 2.2. Just be sure to pick a ROM that has some active development. And despite how good a lot of the ICS ROMs are for the Vibrant I don't know if the hardware is going to give you a completely lag-free experience 100% of the time; especially with multitasking (at least from my experience).
You can try to address the lag by changing your CPU Governor to something like ondemand or scary since those will ramp up the CPU clocks to your max frequency the fastest. Smartass and smartass v2 try to balance performance vs battery and were the usual defaults from when I was testing ICZen, but I always found it better to just go for broke since I'm just looking for a full 18 hours off a charge.
Another thing to try is tinkering with the number of apps the system will keep in memory. Try setting it low (3 or 4) if you're experiencing unusual lag.

Well, no matter what...your rom is going to have a certain scheduler and governor set...same with cpu frequencies.
If you haven't changed them at all, then you are running on the default that the rom creator set it to...or if you flashed another kernel on top of the rom, then you are running the kernel creator's default. I'd suggest, the person above me suggested...going with ICzen with subzero or devil...then I would suggest downloading NStools free from the market place and experimenting a little with the governors and schedulers....
some good schedulars are: sio, vr, deadline, or noop
and some good governors are: smartassv2, lulzactive, lagfree (if that's what you're going for)
...personally...to avoid lag and get good battery, I go with a modified conservative governor with a slightly higher max frequency of 1200 normally and 1300 if i'm playing a very taxing game like idk,...dungeon defenders or something.
Now, you'll definitely experience better performance by chancing the governor and max frequency.
For reference go here: http://forum.xda-developers.com/showthread.php?t=1420742
and to see what I meant when I said that I "modified" the conservative governor to fit my needs...
go here: http://forum.xda-developers.com/showthread.php?t=1369817
If you have any question, just ask! But I really think that your lag will go away once you become more familiar with tweaking the settings to run smooth.
If you are really interested in tweaking your phone a bit more than this however...
you can also try running this: http://forum.xda-developers.com/showthread.php?t=991276/
with the free app "script manager" from the market. It's definitely worth it in my opinion.
Good luck!

Use the smartassV2 governor. It regulates the CPU frequency according to load (sorta like ondemand except it works better).

I'll have v1 of Funky kernel out soon if you want to try out wheatley.
I've been a fan of smartassV2 since the first time I used it on the Thunderbolt. It is as close to an ideal governor as I've ever used. SmartassV2, with a complete sysfs implementation, can be tweaked very nicely. It is a governor that you can really tune so that most of the time it's not running balls out, but it's not loafing along either, which is how a governor SHOULD function. (I like to see a nice bell curve peaking at an ideal frequency, and spiked way out at the bottom frequencies when I look at a bar chart of my time-in-state's.) From what I can tell, few if any devs tune their governors to their kernels. I'm thinking that's how we ended up with a dozen or so governors that are rather similar, yet rarely ideal.

Yeah. Don't use DSB's kernel. I spent DAYS trying to figure out what his kernel is trying to do as far as governors. I'm not going to talk smack about the guy's work, but I will tell you what I know.
I doesn't appear any of the governors have been tweaked for his kernel. It looks like code was just tossed in there and left however someone else wrote it. For instance, smartassV2 has a sleep_wakup_freq of .998GHz, which is much slower than it should be. It SHOULD be near or equal to scaling_max_freq. Likewise, the max_cpu_load (which determines when the cpu should scale up) is 70, a fairly aggressive number, while the awake_ideal_freq and sleep_ideal_freq are pointlessly high. If I had to guess, these look like parameters for a Snapdragon S1 SoC, not the dual core S3 the Rezound has. No matter what governor you choose, it's only active on "cpu0". "cpu1" runs ondemand no matter what. The reason you have trouble making settings for the governor stick is because the sysfs location disappears and reappears for no obvious reason. It appears when things pop in and out (presumably when cpu1 goes on and off line), things are reset.
Cold hard reality is this: You're NEVER going to optimize any kernel out there to it's fullest potential. Either the options aren't there to tweak, or they behave in inexplicable ways. I can't tell you why DSB's kernel (not to single out a dev or his work, but I'm certain that's the kernel you're talking about) does what it does, but it's so far divorced from optimized on such basic levels you're better off not wasting your time.
As an aside:
After getting a rough feel for what some of these kernels are doing, I'm not at all surprised some kernels have had significant heat and battery drain issues. There are things that simply do not work right or work consistently. The devs shouldn't be blamed for this. These are probably the issues they're trying to work around that they inherited from the sources they're starting from and what makes tweaking them so difficult.
I acutely got everything to work. I'm just trying to overclock the GPU.
The whole time that i have had the rezound i have had problems with the cpu settings sticking, and i read somewhere that using a script to set it works best. would this work? http://forum.xda-developers.com/showthread.php?t=1584508. and also since I have not really had luck with them sticking i would like to know what you guys think is the best governor, i was probably going to use smartassv2, wheatley, or pegesusq, but im not sure if they are the best for performance and all the explanations of them dont really tell if they perform in real life. Im looking for mostly performance, but i dont want something that will destroy my battery
edit: that link doesnt work, the download is missing, so what is a different way?
Why would you want a CPU governer if it wasn't to help with your battery life?

You need an overclocked kernel to do that.

well yeah i have that, im running cubed ics kernel 2.3.5, and i just want a better way to make my overclock stick and which governor will give the best performance without completely using up the battery, kind of a happy medium but leaning a little more towards performance. I guess I didnt explain that good enough

These are a bit dated and from another phone, but can provide a bit of insight into kernel governors and their behavior. Keep in mind a few technical points are different for our phone (different min/max clock speeds) but much is the same in general.
tl;dr Smartassv2 should meet your needs as a top performer while still gaining some battery savings. Try with noop or sio I/O scheduler. A modest undervolt, but avoid pushing it.

hey thanks for all that info
I have no problems keeping my Governor (Wheatly) set with System Tuner using the set CPU preference to remember after boot complete.
