Overclocking Samsung Galaxy S2

E

Newbie
I am overclocking my Galaxy S2 to an average score of 4500 on quadrant using Tegrak Overclock Ultimate.

I am just messing with the configs to see what I get but will not push it to far in fear of burning up my CPU.

Current config for testing Benchmark is

1500Ghz
1275mV core
1120mV internal

I am having no glitches with this and things appear stable to the untrained eye/brain. Anybody else using this and what setting you use for what results? I am unsure about the internal mV settings and have taken a bit of a punt with it. Judging by Naphtaline's comments I have a gold CPU (and dont want to destroy it :))

School of performance
You want really noticeable better performance than stock and don't want your phone to overheat.
In my opinion, 1500Mhz is the point.
So, method is the same. Put 1500Mhz and try at 1350mV first. If it's okay after a day, try to lower the voltage 1325, 1300 (if your device is ok at less than 1300mV@1500Mhz, you got a gold CPU^^)
When you got a crash, go back to last voltage until it never crash anymore.
 
Probably just me... but the Galaxy SII seems pretty fast enough on the stock 1200GHz setting and I can see no compelling reason to overclock it... or is there?

Besides... I'm far too old for "boy racer" bragging rights. :)
 
There is no reason to overclock it other than bragging rights, or benchmark scores.

Most apps are not yet utilizing dual core processors, and the phone spec has plenty more to give than what is currently being shown.

(I also have Tegrak btw)
 
Some people actually downclock the processor to 800Mhz and still get the very same smoothness on the UI and in gaming, to get an extended battery life.
 
i read somewhere that its possible to use an app to adjust the CPU being underclocked in sleep mode, to get rid of the lock screen lag? firstly, is this possible? is it recommended? coz im sure it'll drain battery quite a bit more. i upgraded to android 2.3.4 and was told that it'll greatly improve battery life and rid the lock screen lag.. im currently being disappointed on both

The lock screen on my phone sometimes is really snappy on par with the iphone and sometimes really sluggish - almost a second. I was told that it was the type of image that you have set for the lock screen whereas having a lower resolution wallpaper would wake faster. It seems to make logical sense... The battery life itself its fine for me infact I would prefer it to actually go below 10% everynight so I can charge it to maintain a longer battery life which this is hardly the case unless I play with it during the day for long periods of time.

What you are doing to your battery is actually bad for it.

Lithium Ion batteries do not like to be drained completely before recharging. You want to recharge it as often as possible rather than letting it drain below 10% every night.

You will get a much better life span on your battery if you recharge it every night at 50% then you will if you recharge it every night at 10%.

OLDER Batteries work the way you are currently doing it, but these lithium ion batteries do not like being discharged like that constantly.

PLEASE start charging your battery every night, it is cruel to drain him out before you charge him. Plus you will get a much longer battery life span if you recharge him constantly.
 
I got this overclocked @ 1.4ghz.
11+-+1

i think its only snappy when there's an app running in the background, and the phone is still awake.. then its just the screen that needs to turn on, hence the iphone/any-other-android feel. when it needs to awaken, this is when its laggy.. and this is most often the case. it takes over a second for me.

and on topic, thats an impressive overclock!:D
 
Hey, how about overcloaking to 1,4ghz- 1,5ghz - 1,6ghz and playing some games? I heard that 1,5 is quite stable, and it would be + for gaming, but in nature i am scared to burn phone down, becouse when playing games the phone is already warm. So can i do this, (playing about 2h-3h, or not even try?
 
1400MHz is quite possible, indeed most GS2s will probably manage 1500MHz stable with a slight voltage increase, but 1600MHz usually requires a substantial increase which causes more battery drain and heat.

Tbh even a 400MHz overclock is only noticeable in benchmarks. I doubt you'd see any difference in performance when gaming, and if your handset already becomes warm then pushing it further really isn't advisable.

As far as i know, galaxy note uses same processor as S2, but its overcloaked on 1,4ghz, is that true? (Thats make me think i can overcloack galaxy s2 to 1,4ghz without a doubt)

I can't comment on the Note, but I've never heard of a GS2 that couldn't manage 1400MHz.

Nah, you dont understand, i meant that Galaxy NOTE uses the same processor like sgs2, but its just set on 1,4ghz on standart. While galaxy s2 is set on 1,2ghz.
