Hi guys, i was bored and was fiddling around on the setCPU app and noticed the "perflock disabler" its says about OCing the stock kernel would this work on my xperia arc? Or is that a big no go to try and attempt to do the perflock disabler?
Um, aren't you misunderstanding the perflock disabler's purpose?
" Keep in mind that disabling perflock does not enable overclocking, though some overclocked kernels may require perflock to be disabled. Overclocking, in most cases, requires a custom kernel."
Also, it's an option meant for HTC devices.

Which kernels have the perflock disabled? Right now I am using SetCPU to disable it, but I must re-do it everytime I restart the phone. Does Toasts new kernel have it disabled already?
I believe all of the latest FPS fix kernels support OCing (cameras work also!) I'm using the netarchy-toastmod kernel and all you have to do is set your frequencies in SetCpu......or profiles if you want to use them. Just dont leave it OC'd in performance scaling. I've read that can really cut the lifespan of your phone.

Not sure if i'm talking about the same thing. Im talking about the perflock setting in setcpu, i read that you have to dissable perflock after every reset. Do I still need to do that with the new toast kernel?
and everything is good except Set CPU is not having any effect on the cpu. My cpu is not resting...bouncing all over the place. Any suggestions?
PS, I've used OS monitor and SysPanel to try and figure it out. I've killed everything possible but the Set CPU meter if flipping out.
You need a kernel that allows it. And the stock 2.2 does not.
Disabling Perflock
Maybe your answer is at the setCPU documentation site on chapter 10: Disabling Perflock:
“On most stock HTC kernels and some custom kernels, HTC has enabled a driver called "perflock" that constantly resets SetCPU's Max and Min settings”
Sorry I’m new here and still can’t publish URLs, but look for "HTC Dream: G1 > G1 Apps and Games > SetCPU for Root Users [2.0.1] This *actually* changes everything. 07/05/2010"
has anyone tested perflock disabling with the 2.2 rom? i thought about doing it, but dont have the time to test today.
Disabling perflock with setcpu does not work on the stock 2.2 kernel, I read somewhere that the kernel doesnt even use perflock ... don't quote me on that though.

I've seen others mention that this kernel doesn't have perflock either but until I see some proof I say they don't know what they're talking about. SetCPU is having no effect so good chance perflock is in place and working the same the same as ever.
Furthermore I don't see why HTC would remove it, it prevents non-root users from possibly burning out their CPU from overclocking.

All is well now!

Don't you lose camera quality and other things with that kernal?
Hello everyone!
I will overclock my GPU. Somebody know how I can do this?
I have:
Xperia R800i
unlocked bootloader
root
Not very sure about what I'm about to say...
As far as I know you can't, the CPU and the GPU are on the same chip, so if you OC your CPU you're also OC'ing your GPU, BUT, there's also an app I haven't tried yet, I just read about it somewhere in this forums, if I'm not wrong its name is Voltage Control, it lets you tweak a lot of things about your CPU, GPU (what I read), voltages, schedulers, etc, just... be VERY careful.
Hope I was of help
Oh yeah I was forgetting something, you need to flash an alternative kernel to be able to overclock, by just having root access you will only able to underclock.
I recommend you the DooMLoRD's DooMKernel, look for it on the Development forum of the Xperia Play
jhonyrod,
I'm already have doomkernel v10 and OC CPU. (1.6GHz)
Thank you for information.

I'm about to install that app a was talking about, if you give me some time to look around I'll give you more info.
EDIT:
Ok, I installed the app, as far as I can see it has many other options but only for supported devices (the screenshots are actually showing a GPU tab), sadly, our R800 are not, it can only change the cpu governor, the I/O scheduler and the freqs... Maybe I was right since the beginning; CPU/GPU are on the same die, and when you OC your CPU you are OCing your GPU too, even though you can't see it, but in my experience (and benchmarking) it does.
I just rooted my s3 and would like to overclock it a little. Just wondering what the best settings would be and if Set cpu is indeed the best app for this. Thanks in advance and I apologize in advance if I'm in the wrong section.
First you're going to need to flash a kernel that has overclocking capabilities. I highly recommend ktoonsez however if you are not familiar with extreme customization, then faux or lean kernel are better suggestions

I also suggest that whatever app you do use (I use SetCPU as well but they all generally work the same), DO NOT SET ON BOOT.
Since you aren't quite sure you know what you are doing yet, if you input a wrong value or your CPU can't handle "that high" an overclock or your CPU cannot handle "that low" of an undervolt and have it Set On Boot, you will be stuck and have to Nandroid back.
Once you know if certain values work for you, then use Set On Boot.
Hi guys. I'm using DoomKernel v14, so far so good.
I install setCPU and set a couple of profiles, but when I went to undervolt there was no undervolt tab on set CPU. To handle this, I install SetXperia but when I activate setCPU profiles on boot my Xperia PLAY crashed and reboot soon after boot. So, I guess I should NOT use setCPU and SetXperia at same time, problem is I need to undervolt my PLAY so I can squeeze more power from battery.
I read the documentation (well, sort of...) in SetCPU webpage and it states "The Voltages tab is only available with some custom kernels and devices. If the Voltages tab is available, it will automatically show up between the Governor and Profiles tabs. Otherwise, the Voltages tab is unavailable.".
Now my question is: Why SetCPU is not allowing me undervolt when is obvious that DoomKernel v14 allows this (SetXperia allow me to undervolt after all)?, more important, how do I fix it?, if I change to Lupus kernel will I be able to undervolt with SetCPU (will the undervolt tab be enable in SetCPU)?
Thanks.
Ok, I just install Lupus kernel and still there is no undervolt options in SetCPU.
I'm open to suggestions.
SetXperia can modify your voltages: https://play.google.com/store/apps/details?id=com.SetXperia.Inteks.org
It works with both Doomkernel and Lupus.

Yeah, problem is, with SetXperia I can't set dynamic profiles like in SetCPU...
