Hi all, I'm new to the overclocking thing and am wondering if anyone can help me with some settings. I'm using setcpu from the market, but don't want to fry my phone. The default settings are set all the way up as max and all the way down as min. Just wondering if this is a bad idea and if I should change any of the profile settings. oh ya, should I leave the governor setting to ondemand, userspace, or performance. Sorry if this is a lame question, just don't want to break my freshly unlocked baby. thanks.
You should truly avoid any overclocking on a personal level. At best, you could look into the OC kernel offered by Persian.
Honestly, the phones just haven't been tested for any real reliability... Thus no one has any true understanding as to the potential damages yet.
In other words... Feel free to try an OC kernel, but you really won't find anyone that will tell you exact settings, due to no one having a sure answer. Not to mention, OC'ing is always taking a step to the risky side of the fence.
Just my $.02
just curious really as my phone never gets warm or anything running at 768mhz the battery life is also pretty good.
hey,
i don´t think so, because in the worst case your phone will take damage. But this ~770 mhz are about 250 more then before. Im happy with this xDDD
that is true haha, i just dont see it doing much harm if the phone will run stable higher at the same voltage or the tiniest bit higher
No, that's the limit of the MSM7225. (Achieved by adjusting the PLL to its max, any higher will overrun the limits of the chip, and cause it to most likely fail)
i would like to know, if its very bad for the phone, if you let it permanently run with full speed. Ok, if it will get very hot.. thats clear, but is it bad if you have the 77mhz and it is for example in silent mode, or when you listen to some music. Should you ever take some possible speed away, if its not need? (thx)
The hardware life will probably be reduced. By how much, it cannot be said definitively, but, I am pretty sure that by the time the hardware fails because of overclocking, the phone will have been retired long back.
What you are requesting (Dynamically changing speed) is exactly what Speed Governors (Performance, Internative, OnDemand etc) do. If you are on CM7, use Smartass Governor, because it's the "smartest". If not, then use Interactive governor.
i use ginger yoshi... and sometimes it sais that the sd was removed. Could overclock be a reason for this?
I dont think so. I got the same issue once, and formatting the SDCard fixed it.
ok i will try it thanks

I have a sense rom on the wildfire, so I will try Interactive Governor. Do I still need SetCPU in order to use it?

To use overclocking and governers on sense roms, oc kernel and application like setcpu are must. Setcpu has governers too.

Looked at JokerDroid's thread and it says about version 4.2
■ Kernel : nFinity Kernel
■ Build Number : 2.37.415.1
■ CPU Overclock : 710 Mhz

So this means it has an oc kernel?

Yes, it does, and it is overclocked to 710 MHz, by default.
I don't know anything about overclocking on my Samsung Vibrant T959. I tried to.. I installed the Glitch Kernel HL. with CM7. Can't get to 1.2 ghz at all. I don't know what to do... Do i have to mess with the mVs at all? Please help I'd appreciate it. Anyone recommend an app to use to overclock? I'm using Voltage Control atm... Please help. Thanks.
Set cpu in my opinion is the best app to overclock.
Simply Honey 5.0 w/ 1.2 Bullet kernel. Badass Rom \m/
Agreed, setcpu would be your easiest bet.
Just install, open, slide the bar to 1200 or whatever you want.
I would recommend putting a widget on your home screen.
Makes it really easy to see what you're set on, and easy to modify.
Also, you can create profiles, like under clocking to 400 while the screen is off.
Install quadrant to get a rough idea of how the overclock is according affecting performance.

I disagree with these 2... voltage control is fine... and oc is very straifhtforward... get oc kernel, use oc app to oc... forget wut they said about the profiles, from my exp, they only make things worse. Just oc and dont touch mvs

Antutu's CPU master is another OC alternative for ya, if you are too cheap to spend money on SetCPU that is.
setcpu. best so far for me

Agreed! Antutu does have OC capabilities and is a better Benchmark app IMHO

- Agreed! that messing with voltage is more trouble than its worth.
- Disagree! that profiles make things worse. It really depends on the settings. You should never UNDERclock your "max" to anything less than 800mhz.
For example: I have 1 profile set, its a High temp profile. When the phone reaches 125F setcpu resets to 800mhz(max) - 200mhz(min). Until the phone cools to under 125F then setcpu bumps it back to 1.7Ghz(max) - 200mhz(min).
Trust me this happens often and I'm glad I have that set, haven't had any problems with it.
Setcpu seems to be easy for me!
Hey guys,
I want to make a slight underclock and undervolt my new S4 i9505..used to use Voltage Control for my S2 but I think that one's a bit outdated. Which apps do you guys use?

If you flash perseus kernel you'll get stweaks with it and it's pretty deep level app to o/c u/v...You can do also color calibration and sound enhancements.

SetCPU for root, is a popular one, but i haven't rooted my S4 yet so i am not sure if it works for it.

Had a look at some of the apps, it seems like none currently offer complete support for multicore power saving, like for hotplugging all four cores in the S4. Also i thought Perseus kernel was only for the Octa Core variant I9500?
It is simple, tested on my nexus 6, just go to system/bin and delete mpdecision, then install an app that controls kernel, like kernel adiutor, raise min freq of cpu to 883000 mhz, then set apply on boot, reboot phone and enjoy lagfree and smooth super battery life
you are my hero

Isn't enough to just turn off mpdecision in the kernel app?
this only works for stock roms? I can't find any mpdecision file on /system/bin

if it turn off the 3 sec boost of mpdecision yes

Can you tell me if it's the minimum CPU frequency in the CPU tab or in the CPU governor configuration?

Disabling in a kernel app will accomplish the same thing. The reason you are seeing a change in battery life is because of the 3 second input boost of MPD. Most of the custom kernels have a generic touch boost driver that is set to 1 second or less to take the place of the mpd boost and increase battery because of the decreased boost time.
MPD works great for some people and not for others. It is greatly dependent on your usage habits. For my typical usage, with mpd on, I average 6-7 hours of screen on time. If you are a gamer, where you are constantly touching the screen, mpd will adversely affect your battery life because of the constant boost.
As a kernel developer, I definitely would not recommend deleting the mpd binary. I would suggest trying a couple of different kernels and/or configurations to accomplish the same results.
lol.. seriously? i guess thats one reason that ive disabled mpdecision for the last 3+ years on whichever nexus i was on, but not the main reason
How can I turn mpd off on ex kernel manager
you don't need a kernel app to disable it BTW. all kernel apps do is provide a ui for you to use. it can be done via a terminal emulator app.. type,
su(press enter)
stop mpdecision(press enter)
and that's it.
I'm using kernel auditor and in the CPU hotplug section the first listing is mp decision. Is that what needs to be disabled?
OK, silly question.. do you know what mpdecision does? do you know what disabling mpdecision does?

@simms22 good point here. This is good for everyone to know. If you disable mpd without a replacement, you risk all cores not coming back online after deep sleep. Mpd doesn't actually control hotplugging, it controls input boost and onlining of cores.

and that's exactly why I disable mpdecision, so I can have all 4 cores active at all times.

When you say without a replacement what are you referring to? Trying to learn here..

A replacement such as Zen, Mako, Blu_Plug, etc.
Also, (just an FIY) Zen isn't really a hotplug (it keeps all four cores active at all times, unlike Mako, Blu_Plug, etc). It's still lumped in there for some reason.
I highly recommend disabling MPDecision. You know what MPDecision stands for, right? MakePoor Decisions

I'm running elemental x now and I can't find mp decision on kernel auditor. Do you know if it is included with this kernel? If so how would I disable it?

i believe its already disabled in elementalx kernel. anyways, you can always use a terminal emulator app, then type..
su(press enter)
stop mpdecision(press enter)
thats all. all kernel apps do is give you a ui to whats already available.

Some kernels come with it already removed. Check the features section of the original post in the Elemental X thread or try searching the thread.
I can say from experience that Kernel Auditor doesn't give you access to all of the adjustments in Elemental X. Some features are only accessible through the official Elemental X app, so it might be there, but you can't use Kernel Auditor to adjust it.
