I'm running the newest setCPU and I've come into a few problems.
The X10 has a processor speed of 384000kHz. When I got to set a profile, lets say the <50% battery profile, the max is set to 998400kHz, which is something like three times the speed of my processor. Wouldn't that blow the chip instantly if it overclocked that high?
I've try'd using recomended settings but it won't work, it's still the same. I can't set anything lower then the normal CPU speed since on the scale it goes from 384000 to 245000 and then stops.
What can I do?
Oh... that problem!....

Actually the processor has a speed of 1 GHz so 384000 is minimum and 998400 is max.

Just downloaded Quandrant to run a test, a little bit confused why it says the current clock freq is 800mhz? but says the max is 1200mhz. Is this normal, should it not be running 1200mhz all the time ?
Also I can run the tests, but it won't connect to the server for results or download the results browser yet I can access the interent no problem everywhere else as connected to my home wireless ?
Cheers Guys.
I presume the CPU runs at 800MHz most of the time, but automatically boosts power when it's necessary. No point in having the phone run at 1200MHz when it's idle, just a waste of battery power.

IMO the default frequency is 200Mhz, it will be boosted to 1200 for intensive tasks.
Excellent Cheers Guys,
So I take it if I update to the 1500mhz firmware I can set it a little higher and it will go to the 1500mhz as and when it needs it ?
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.
Hello,
I dont know if it is normal, but when i check with cpu spy, it shows me that i use for 3 hours with the cpu at 1400 Mhz, and i dont remember playing games for the day. Only internet and listening to radio
I thought with the power saver, it would limit the CPU .
Is It normal ?
I think its normal. CPU is stockly clocked at 1400 mhz.
And every app uses cpu, whether low or high, calculations are required by every app and most of these are performed by cpu, so cpu is used.
correct me if i am wrong though.
That is certainly not right, something is keeping cpu at max frequency, so you need to find out what

Yeah i think about the same thing
Even when i reset the cpu spy stat, immediatly, it shows me that something is using it at full power for 20s, even when i close down all the apps and clean my memory
DO you know an app who shows which app use how much Mhz ?
Just finally got around to rooting my USA SGP 5.0 yesterday and download SetCPU 2.24. I set the max clock to 400MHz but noticed that it would periodically jump up to 800MHz. Am I to conclude that it is not properly setting the max speed? ie. not doing anything at all?
thanks!
No, this is normal for this device. When you touch the screen, the driver or the kernel increase the speed to 800MHz, but when you let it go, it will jump back to whatever you set in SetCPU. The driver or kernel overwrites the settings, this is done by Samsung to increase the responsiveness of the device. There's nothing you can do about it.
Interesting... So I want to be able to set a profile so that when the screen is off, the max speed is 200MHz. I am assuming that listening to music does not require the CPU to be clocked at max speed. That said, do we know if the CPU automatically clocks down when not needed? If it does, then does that mean that SetCPU is doing nothing to help with battery life?
I don't know how well the CPU clocks down when not needed. Run some tests with and without caping the CPU and see what SetCPU shows you in terms of clock speed. I have SetCPU on my device because i like to set exact limits to my CPU and not rely on some algorithms to figure it out.
It seems to work whenever I switch the governer to ondemand. Conservative, not so often.

If you can buy tegrac overclock..you can undervolt any FQ and overclock how many you want.

Nevermind... I just uninstalled SetCPU. I had set it to max out at 400MHz. I surfed the web for a while and then watched youtube for 1.5 hours and noticed that I dropped from 70% to 45% battery life. I've never seen my battery drain so fast, even when watching full movies. I might give Tegrak a try but I think I'm done with SetCPU for now...
Hi,
The new games started to demand more cpu and games like Modern Combat 4 lags as hell when cpu is 800 mhz, when it is 1.2 ghz the game is smooth. I am experiencing this problem on a few more games.
I installed an app that shows cpu temp, when cpu reaches 65 celcius, it downclocks to 800 mhz, when it becames 60 celcius, it becomes 1.2 ghz again, and this problem makes major lags. The problem is the phone reached 65 celcius not more than 1 minute and impossible to play without lag. Undervolting is not a solution and my gpu is at stock speed and voltages.
Is there any solution to lock it to 1.2 ghz. Even I set the cpu to performance governor or set the min scaling speed to 1.2 ghz, it still downclocks to 800 mhz. I think increasing the throttling threshold to 80 celcius or sth should solve the situation.
Use an app like setcpu(https://play.google.com/store/apps/details?id=com.mhuang.overclocking) you need root but you can just set up a profile that if modern combat 4 is running then min CPU=1200 and max= 1200

Thank you, but the phone is stubborn about downclocking to 800 mhz. If the phone reaches 65 celcius, there is no way (that I found) to prevent downclocking to 800 mhz.
