I'm trying to develop an OC'd kernel for Pantech vega racer 2 phone. It has the same hardware as HTC Evita.
I was able to overckock it using zarboz' and rohan's work. But the frequence is drops down to stock 1.5 Ghz while the processor is on max load.
For example, I started SetCPU stress test and after few minutes checked max freq. It was dropped down to stock 1.5 Ghz.
The same with Antutu bench. Even with OCing up to 2 Ghz in final resulst it show 1512 Mhz and freqs are dropped down.
Due to the lack of development for this phone, I can't find any examples of OC code especially for this phone, so,Devs, I need your help.

Thermal throttling is your issue.
It reduces the CPU frequency a lower one to protect your battery from heat...
Try editing or deleting thermald.conf from /bin.

This thread is purely a discussion about our phone's processor ability to be overclocked.
Does anyone here have any idea how our beloved xperia mini/minipro/lww processor can be clock as high as 2GHz as opposed to its default clock speed(1GHz)? If you carefully goes beyond our phone subforums into the realms other phone you can see that much of the phone there can't be overclock as high as our phone can go. Eg; other phone with 1GHz processor can only be overclock to 1.3GHz.
Any ideas? Developers facts can be very helpful.

Well 1600 mhz is stable for me,I will try 2000 mhz as soon I install supported rom.About 1300 mhz max for some models looks stupid to me,I didnt read post that says that.

I've tried 2GHz on my phone, seems to be okay w/o any instability issue.
Fortunately our phone isn't maxed out at 1.3GHz, almost all kernel for our phone support up to 2GHz, what I meant is, phone like x10 seems to be maxed out at 1.3GHz. Just small increment from 1GHz to 1.3. While our phone can go all the way up from 1GHz to 2GHz doubling its default clock speed.

i've only tried to run benchmarks on my phone up to 1.6GHz,
did not try higher speeds because i am worried about the CPU might break...
as per x kernel latest release, they have set the limit to just 1.8GHz.
seems that would be the safest our CPUs would reach but still its not same for all units.
i am not completely aware about the technical specifics of the CPU but it seems that it could have been made that way.
the only thing that would limit the CPU capabilities is the temperature and the battery capacity, since running an overclocked CPU on a 1200mAh battery is not that efficient.
You're not exactly correct OP.
My Active, with the OC Spartan kernel, goes up to 2Ghz on my device and its perfectly stable.
On my Desire Z however, stock Mhz is 800, and i have oc'd it to 1.9Ghz stable, thats over 140% (russian election pun not intended ) oc. It is one of the most highly overclockable devices yet.
So it's not only our devices that go to 100% of stock speeds. Ill remind you that companies, take some "malfuncioning" processor chips that might have a specific part of them not working, lower their speeds to make them stable chips, and then ship them out to manufacturing.
That is why some devices dont go over 1.9Ghz. Its just a matter of quality of the CPU. I know this because back in the days of the ATI9500, which was actually a ATI9700Pro, just underclocked because a pipeline was malfunctioning, so instead of throwing them away, they locked the pipeline and sold them as a lower budget Video Card. With some tools though you could unlock the pipeline and if you were lucky you could have an ATI9700Pro in the price of a ATI9500
I have one question while we are on this topic.
Our phones have MSM8225 chipset while the Arc S has MSM8255T (clocked at 1.4 GHz). I'm curious, is there any noticeable difference between these two chipsets? If there isn't why aren't our phones clocked at 1GHz?
The reason these go by 8255 and 8255T are stated in the post i made above. Same chips, different quality. It seems that not all 8255 can be stable up to 1.4-1.5Ghz, so they released a cheaper 8255 line that is clocked at 1Ghz.

You are completely right but I have to say that architecture has something to do as well on my old x10 mini arm6 I had a 600 MHz processor going at Max of 800 and something and now my lww arm7 can go as high as 2 ghz lol.

The maximum CPU clock frequency is placed by kernel developer, what he thinks is fine. It is not that phone's CPU can really put up with that high clock frequency.

Sure then the cpu had nothing to do when you clock a 600 mhz cpu to 845 mhz and it crashes?? come on that is a lame thing to say in this thread

What I ment, was that the actual maximal overclock frequency, where you can set it, is set by kernel developer.
You can set the CPU max frequency 1Ghz, 1.2Ghz, whatever. But the really maximum, which you can set, for example 2Ghz in Rage Kernel, 1.8Ghz in X Kernel, is set by kernel developer.
It is not tested that phone can put up with that high frequency. That is your own responsibility to try and risk.
Imagine cpus being made like cookies.Although you use the same ingredients not all cookies are baked the same, not matter how good your oven is.Cpus get out of the "oven" and tested for stability.The less stable are clocked lower, the more stable higher and that depends from the voltage they need to run and the maximum safe temperature that is allowed so the chip can last long time.So they say that chips which fall between A and B specifications (temp voltage etc...) are going to clocked to 1 GHz and those that range between C and D to 1.4 GHz.But those who are close to A are not the same as B, same with C and D.That's why some cpus clock better than others even though they're clocked at the same speed.At least that's how computer cpus were made if i recall correctly.
Its marketing trick.
Why should I buy WT19i when I can buy Arc S with higher clock rate.
Same processor because if processor is diffrent they would need to make new S1Boot,if in arc s is new bootloader patch wont work.

Hi! I have problem with perseus Kernel If I overclock cpu a little bit, All the same the problem (If I start play game some time it will restart), it does not matter how much overclocked. I tested 1.7Ghz clock and test it For 1375mv, 1400mv, 1425mv, and it's not effective and between a perseus rom freezes lock screen and I have to restart it :S, siyah kernel will not let me even overclock more than 1.5GHz can someone help me with this problem :laugh:, I love overclocking :silly:

Okay But, why I'm not able to overclock 1.8GhZ its show me 200-1.5GhZ I tried overclock stweaks, cpu master, set cpu, and Foxhound extras but not help I try flash siyah again If that help.. Block story max settings eat really MUCH performance
I'm not even able hit over the 1.5GhZ and it show me 25-1.5GhZ (((
Anyone?
Anyone know what I do wrong if I'm not able hit 1.8GhZ?
yes,, your cpu isn't up to it, simple. With overclocking make small steps, note what you are doing, experiment with voltages, but all chips are different so experimentation is the only way, along with lots of reading and learning, skill aided by searching

okay But why this perseus give me overclock more than 1.5GhZ But Perseus is so buggy :S and I can normally overclock Gpu with siyah kernel but If I run test I am not note difference, 1 better fps for 700MhZ GPU Clock My Phone is so strange

you have to understand the fact that the kernel is in alpha stage, so if you dont know what you are doing you shouldnt have flashed it. and also all chips are not capable of handling higher frequency, 1.6 ghz should be asafe bet for all processors..
700mhz in siyah makes a big impact depending on the benchmark you run.. check the thrread in my sig for more info.
Thanks all for posts! I figured it out, I give more juice for all these steps for perseus alpha And not anymore reboots. 1.8 GhZ 1450mv 1.7GhZ 1400mv, 1.6GhZ 1350mV, 1.5GhZ 1300mV, I run now 1.7GhZ for dual core mode, I'll try soon run my phone quad core mode . But I can't overclock my gpu with perseus and siyah rom doesn't give me overclock more than 1.5ghZ DD so strange Ps: 1.7 GhZ Dual core My Cpu score is 8123 and memory 5538 on quandrant benchmark.
Edit: If my phone a little bit overheat it reboot same thing is 1.6GhZ, 1.7GhZ, 1.8GhZ. 1.6GhZ I run stability test about 1-2min and it reboot, Battery About 41 degrees Celsius :S
Why in the name of all that is holy would you overclock your CPU, and then run it in dual core mode??
You would be better off leaving it at 1.4ghz in quad core mode.
That seems pointless.

I will do later in the evening siyah kernel video for overclocking problem
Me and my friend were benchmarking together (we both use MiniPro). I use Serenity ROM and my friend uses MiniCMSandwich ROM which is based on AOKP and has overclocking option in the ROM Control. I'm using AnTuTu CPU Master to overclock mine. In AnTuTu, the maximum value for overclocking is 1.6 GHz while in MiniCMSandwich ROM Control the option is up to 2 GHz. My friend just wanted to test the 2 GHz (our devices are working fine under 1.6 GHz) and suddenly after he picked the option, the phone shuts down automatically (gracefully, fortunately). Though he finally managed to get everything back (by quickly changing the overclock value back to normal at boot), we're still curious. How far can we overclock this device?
It depends on the kernel you are using. Normally our device's kernel allow overclocking up to 2Ghz max. DO NOT overclock your device unnecessarily! It will eventually fry your central processing unit.
Hit thanks if I've helped.

Don't overclock above 1.3 Ghz.... Unless you want your device to be fried..... Performance at 1.8 Ghz is practically same as at 1.3 Ghz... ( Not talking of benchmarks ) .....
Sent from my WT19i using xda app-developers app
1.3ghz performance is the same 1.8ghz really? yeah im not talking about benckmark
coz theres a game that force me to use 1.4ghz. using stock up to 1.3ghz will produce stutter sound in my case (have tried in st17i n r800i)
i dont feel any heat it produce by overclocking 1.4ghz coz i undervolt it. my device only getting warm when i plug the charger n thats normal i think
Hi all.
This is my first post here so forgive me if I've put it in the wrong forum.
I recently (6 days ago) bought a new phone, Ezio i95.
It looks like Samsung Galaxy S3/S4.
The specs are:
Quad core 1,8 GHz
2 GB RAM
Dual Sim
5" Super AMOLED screen (1920x1080), 440 ppi
But... In Antutu benchmark system info it correctly says that it is 1,8 GHz CPU (1741 MHz, to be precise). But, when I do the test, it sees only 1,2 GHz. When I try any app that does cpu scaling or any other cpu work, it also sees 1,2 GHz.
I searched for it on the net, but I didn't find anything conclusive. Actually, it seems that the CPU clock is really 1,2 GHz, but I don't know why and how do they sell it as 1,8. And how the hell Antutu sees it as 1,8?!?!?!
Here are screenshots:
h ttp://imageshack. us/f/9/kocl.png/
h ttp://imageshack. us/f/5/o0ph.png/
And here is from mediatek wiki:
MT6589[a] Cortex A7 (ARMv7) 28 nm 1.2*GHz quad-core PowerVR SGX544 @ 286*MHz
Any Ideas?!
Thanks in advance.
System won't let me to post a link, because I'm new, so I tried this workaround. Hope you don't mind. I've put two spaces.

I am not familiar with the device or the ROM you are using (stock?). But if you install cpuspy it will tell you all the freqs that are allowed and how much time your cpu spends at each freq. My guess is that the freq table goes up to 1.8GHz but that somewhere the maxfreq is set to 1.2 GHz. You might be able to up the maxfreq using an app like setcpu. The cpu you have is rated to 1.2 GHz so any overclocking you do comes with the risk that you will damage your phone. Basically if the cpu is getting hot....better back off the overclocking.

Every app I tried, including SetCPU and CpuSpy, shows 1,2 GHz as max frequency. As you can see on screenshots, Antutu benchmark shows in system info 1,8 GHz (1741 MHz actually), but in test it uses 1,2 GHz. TBH, the only place I saw 1,8 GHz was in Antutu, not anywhere else.
I contacted the seller, and he is trying to convince me that the phone has CPU Booster and that frequency is really 1,8 GHz. I now sent him screenshots in order to convince him that he is wrong...
I researched that cpu, mt5689 and its max freq is 1,2. mt5689T is 1,5 GHz, but this one is without T.
Kernel version is 3.4.5, from 19th June this year
Baseband version: MOLY.WR8.W1248.MD.WG.MP.V6.P4, 2013/05/04
Android version is 4.2.3

If that anything means to you...
I am not trying to overclock my phone, I just want to be able to use what I've payed for. I could have bought 1,2 GHz, but I payed for this one and I want to use it, that's the poing...
Unfortunately, only after I bought it, I found all this. I didn't inform myself enough, before purchasing...
Thanks anyway
The seller is still trying to convince me that the max cpu freq is 1,8 GHz, with cpu booster, but I still cannot see or use it in any app, except that Antutu benchmark sees the 1,8 GHz as max, but still uses 1,2 GHz.
Chipset and cpu is rated to 1,2 GHz, as I saw on mt6589 reviews, so I think that I am fooled...
Good morning, my name is Jorge Martinez, I am another ezio buyer i95, I arrived with several flaws, the most serious the gps it is impossible to make it work, even after following many online tutorials.
The on / off button sometimes gets caught and resets.
The headphone connection is not good and sounds bad.
Reviewed this to the salesman told me they would give me support, etc, etc, told me I was going to wait to send another new model, gave me all kinds of options, but ultimately it only to gain time.
Once you pass the time of the vote, and has forgotten all its commitments and ripped me off.
I recommend everyone to not deal with the seller, who has only good words but deceives.
I hope my mistake serve for one to be saved from falling into this trap, but also effectively tells you it's quad core 1.8, it's actually 1.2.
Greetings all, I hope this information will be useful.

hi,
I have read that some of the specs get rewritten within the operating system to fool antutu.
However I am also after a copy of the stock rom. I have a enzio s89 that I have bricked before I made a rom copy. This ezio i95 uses the same processor and is about the same size Maybe it will work in mine.
Are you able to download MTK droid tools and make a copy of your stock rom please. That is always worth doing in any case.

But unfortunately, I have seen that works only one of the four cores!
After a long search I found a CPU Editor for DualCores and Beta QuadCore. But unfortunately this does not at all - the version for DualCore works fine.
Has anyone similar experiences or can someone give me a tipp?
It is this mod: "CPU Editor QC Beta 1" from Smokin1337
It shouldn't need all four cores on unless you're running something that's cpu intensive. Normally it's set to use one core and as workload ramps up the other cores come online.
I run AnTuTu Benchmark and switch to CPU-Z = one core at 1512 MHz overall 25% Load!
CPU Benchmark the same result, one core and the rest ist "stopped".
Any idea?

What's were your scores?
It seems to be a stock kernel problem, try running crpalmers kernel.
AnTuTu score (without CPU Editor) 11247 and with DualCore Fix 13978
