[Q] Overclocking ?

I have a question: why I can't overclock my SGS past 1.2 ghz. When I try to set for example 1.3 or 1.4 it freezes and I take out the battery in order to make it work again. Is there something I do wrong, is it a general problem with more SGSs? If somebody can , I really appreciate. Thanks

it is a kernel thing.
the kernel has to support those frequencies.

I tried with tegrak overclocking with voodoo kernel (the application itself doesn't need a kernal that supports those frequencies) and with Supe Optimized Kernel (1.4 ghz) and voltage control and setcpu and is the same result:freezing.

Not every cpu is capable of stable overclocking past a certain threshold. You have probably hit the max speed your cpu can maintain.

I agree with you but then why there are other people with the same phone as me that can overclock them at 1.4 ghz?

With CM7 or miui and either bilboa or zacharius kernel you can overclock to 1300 but I haven't found a kernel that allows 1400 either, I think those that are doing it are hacking the CPU settings themselves.
My phone gets really hot at 1300 running apps like dungeon defender so 1400 might just be a bit too much

I am using Darky's 9.3 ROM but my problem is that i can't even touch 1300 mhz because my phone freezes.

Maybe a dumb question, but, do you overvolt as well as overclock? Maybe the cpu isnt getting enough juice?

+1... not sure if there is much benefit at all to undervolting.. it just seems to make it immediately less stable...
can someone shed some light?
I've seen someone test this on another forum somewhere, and the difference the undervolting makes to the battery length is negligible..

The principles of ovetclocking a PC also aplly to phones. Undervolting reduces the power available to the CPU. Undervolt a little and you'll save a little power. Undervolt.too much and the CPU won't get enough power to do basic functions hence freezing.
Every CPU has a limit to which you can over clock. You can overvolt to a point but then then the CPU reaches its limit.
From what I understand (read in another post) the hummingbird processors are not suited to overclocking. Where the arm such as that in the Motorola milestone clock really well. (You can oc a 600mhz milestone to 1ghz before you start seeing instability)
Hope this helped.

I understand the intention of undervolting as i am pretty good with PCs. Got my good old i7 overclocked constantly. But undervolting on the SGS has yet to show me any definitive advantages.

Did anyone go higher than 825MHz?

Title says all.idk if its even possible

Are you smart?
Sent from my X8 using XDA Premium App

When I go higher than 748MHz, it causes bootloop.
I also think that overclocking is useless, well you get a bit higher Quadrant scores, but it also causes higher battery use, and it´s not so good for the CPU, I think.
And going higher than 825 MHz is, in my opinion, mad.

@xperianpro-dont troll,its just a question.
@codfreak-well,i personally dont use overclock because i need battery,and i dont use my phone for anything else beside wifi,facebook and taptalk.sometimes games but not much.for me normal frequency is from 710mhz to 787mhz.

Hi, how did you get this score ??! which ROM use ?
thanks

My phone can OC to 768 Mhz with no boot/restART
But when i test my phone @ 787 Mhz or higher, it's good at SetCPU application but when i'm going to home (LP) my phone reboot(??)
Luckily i got 768 because no many people can get that! haha

@Xperianpro/as-mario
Our processor might be able to go higher but the problem is the voltage. Each x8 has a slightly different voltage supplied to the processor so some can OC to 825, some can OC only to 748 etc. I can OC to 768. I heard that the LG GT540 can OC to 900 MHz.
--
Basically ppl can OC to 825 but it's kinda rare. Usually, most can OC to 748 only. It might be possible to OC to over 825 but it will be unstable for most people.

Our X8 Voltage is 3-4-5-6-7
if you wanna get higher frequencies you must overvolt and melt your Processor

[Q] CM7 7.2 by squadzone safe for daily use?

Is cm7 safe for daily use? the one made by sir Squadzone .. "especially for games" cause i really9x like his works..
Do you mind posting your opinions and experiences..

Have you encountered any problem sir on your phone using cm7?
I presume your using overclock kernel by Mr Squadzone ..
Did it fry your processor sire?
Btw thanks very much for your replies .. i really appreciate it...
I'll press your thanks button after i post my reply.
waiting eagerly for your reply...

not much problems.
for me, just the battery, some games doesn't run properly, the camera sometimes shows contrast line, and the radio is sucks.
overall, this ROM is perfect.
the overclock doesn't harm the processor.
it safe.

Actually the overclocking kinda hurts the processor. Well since you push it over the limit it is used more so the life of the processor is getting shortened.

But why the other ARM v6 have default cpu more than 600mhz?
It has the same processor isn't it?

I'm not into 'games' so much.
But I've tried Fruit Ninja, Cut the Rope, NFS Shift. and it runs well.
I've used this ROM for almost a month, and I didn't see any bugs yet.

they are included in the armv6 family yes but still the do have set lifespan.
think of it as processor of desktop, (same facts actually about OC).
ex:
armv6 v8 = default 600mhz = 5 years lifespan
armv6 v11 = default 800mhz = 5 years lifespan
intel e2200 = default 2ghz = 5 years lifespan
intel e2100 = default 1.8 ghz = years lifespan
now both arms are in the same family and both desktop procies also, the difference is that in the architecture set they do have different default freq which are set by manufacturers to maintain stndard life.
now if you push the v8 to 800 it will lessen the lifespan, yes it will be the same freq as the v11 but due to the design it will not have the same lifespan if you OC'd it.
it can be the same theory on motorcycle engines,
example would be the xrm 125cc engine.
it you would like it to be as fast as a 150cc engine you have to bore the piston hole the same size as what the 150cc has and change the piston size and rings and the carbs. but doing this will also push the engine to its limits. why because the safe design of 125cc engines are set as 125. if you go any further you will have better performance but less lifespan and can cause the engine to break faster even with good maintenance.
like your body, example would be.
by default you can last 4 days without sleeping but all you have to do is watch tv ,but you can't last 4 days without sleeping if you will jog 5 km every morning.

So, if my arm v6 which is default 600mhz overclocked to 782, how much time left until it's "dead"?

because in the 800MHz chipset the only difference is cpu frequency thats it

"Incredible"

Totally impossible for the MSM7227A.. the MSM7227 at 800MHz should work though, the only difference from ours is that it is stable at 800MHz.
The hard part is to get one and replace it without damaging the phone
I'm sure it's also possible to increase the RAM with a identical chip but with more space and reprogram the phone to address it properly.

The MSM7227 at 800mhz is actually MSM7227T. The recommended frequency for our chipset is 600Mhz. Lol it's not possible to change the chipset for to either of them, the skill needed to do that would kill you.

You know what? You are right, i have been seeing in the news that thousands of people die every week because they learned how to rework BGA chips.. The knowledge needed is so insane that the brain explodes.
What the hell are you talking about dude? Reworking/ flowing / balling is simple when you have the right equipment.. The hard part is its price. Or were you thinking of doing it with a soldering iron?
About the chipsets, they are the same thing.. the turbo version is stable at 800MHz, the normal is not.. It's the same as changing your computer cpu from a 2.5GHz to a 2.7Ghz.. the pins are the same, everything is the same, the 2.7 just draws more power.
I am not 100% sure it would work because there are lots of variables (software and power wise), but at least 90%
I'm not screaming IMPOSSIBLE or mocking the dude like everyone else because it can actually work.. it's just very impractical, it would be cheaper buying a new phone.

I already have hot air soldering station and other tools but how can I get a chipset moreover where can I get the datasheet of the chipset I searched alot but havnt found any

[Q] Overclocking to 1000Mhz

Hi! i was wondering if Xperia X8 E15i could be overclocked to 1000MHz because i heard from my brother (he had this phone and then i got it) and his not sure because its not possible anymore to do it anymore.
My brother had my xperia long time ago and he had 1000MHz then later when he gave it to me he unrooted it and make it to normal Xperia

864 mhz is max for msm7227 (or armv6...)
you cant go higher
and 864 is very unstabile:good:

High frequency-less CPU life
low frequency -long CPU life

@senci00: your brother is joking only with 1000MHz
@fotak-x: no, you can set higher frequencies than 864 with a modded frequency table. I made an experiment earlier and reach 921,6MHz, but:
-the phone was really unstable
-needed really cold environment (around zero celsius)
-to reach this frequency needed to extremely decrease all other frequency (axi and ahb bus), so the phone was slower
@Gogeta: basically the arm core can't produce enough heat to get physical damages due the overheating (the most critical part is the soldering what need around 280C temperature to damage, hard to reach it with 1-1,3 voltage and 100-200mA)

So we can overclock to higher value without any problem???
I mean it doesn't damages anything so we should increase value

Theoretically yes, you can set high frequencies with minimal risk. All arm cpu have extreme low power consumption (compared to the x86 cpus), the physical damage due the heat is minimal (but more than zero) The overclock ability of each 7x27 soc is different and depends on lot of thing (damages in the silicium structure, soldering quality between the core and the case, etc...). Some soc unstable on 700MHz, some working good on 800+ MHz. And the most x8 owner have "low quality" cpu, because under the manufacturing procedure all cpu tested, and the high quality cpus (what stable on 800-900MHz) marked and sold as 7x27T (turbo) with default 800MHz (this is normal, usually the manufacturers sold the damaged cpus with lower clock or disabled features, for example: you buy an i3 cpu into your desktop, but maybe the cpu manufactured as i5 with damaged core, and after disabling the damaged parts, sold as i3).
