[Q] Best CPU settings?

Which are the best cpu and memory settings for x8?

Wich rom do u use?
If is minicm, you can easily go to, 729 or 748 mhz with no reboots, smooth and stable

Which is the best app?

You must test which frequency is best for you because every processor is different. One can run on 729 MHz without problems but other can't. You can use CPU Master or SetCPU from Market or other apps

but no need to use 3rd party apps if using miniCM, since you can change OC in cyanogenmod settings
and it's just as dbts25 said, every cpu is slightly different, some people can't even overclock cpu to 614 mhz, and some can go over 800...
i prefer using 691 or 710, these two are pretty stable for me, and my limit is 729 - i can't go higher no matter how much i try - the phone reboots immediately
i'd recommend you to check it yourself, and when you find a good, stable frequency, reduce it by 19 mhz - you'll propably have less reboots, if any at all it's more secure to do so in my opinion.

CM7 Nightly75 CPU Settings?

First time CM7 user here. Just got done installing nightly build 75, everything seems to have gone well. Have dals 4/24 kernel installed, but I can't seem to figure out why it limits my max frequency choices > 800 Mhz to 1200 MHZ and 1300 MHZ. I'd like to set it at 1000 or 1100 MHZ as I'm getting random shutdowns; I'm assuming that my nook can't handle the high clocks. Should I just use SetCpu to set my clocks?
Edit: Nvm, setcpu won't work either. Can't choose anything between 800 and 1200
Thanks

I haven't updated in a while. But if you skip dals kernal and just use the stock CM7, it should let you set it to 950 (i think).

Got the same question for th e 4/24 kernel which I just installed (running Phiremod 6.2, BTW).

Might give that a shot. How that I get a hold of the stock N75 cm7 kernel? would prefer not having to format and install everything all over again.

You're not supposed to use SetCPU with CM7 for clock speeds (it can create a conflict); generally recommended to only use the built in CM7 settings.
The reason those are the only speeds you are seeing, is because those are the set speeds in the Overclock kernel itself (that is how it was designed).
So, you can try going back to the original nightly kernel (I don't think those kernels are posted by themselves); OR you can also try flashing the stable 1.1 kernel by Dalingrin. This has more speed than stock, but less speed than the test kernel you are using now.

How do I go about updating 4/04 kernel for ext4 compatibility? Browsed the forums and was only able to find the 4/24 one.

Just flash the version of CM7 that you like over it. But don't wipe your Data or Cache. If you Flash CM7 over CM7 it should be cool. As always make a back up if you're concerned.

how to overclocking htc wildfire

i have have rooted htc wildfire and have installed CM7.1.
can any1 pl guide me how to over clock the CPU.
after entering cyanogen-mod settings>performance>CPU setting, i have min CPU frequency which is currently 352 MHz and max CPU frequency which is currently 528MHz. do i need to change them directly or do i need any kernel for this?
regards.

Just change the values. CM7 comes with an OC kernel preinstalled.
Sent from my HTC Wildfire using XDA App

which values are best for Minimum and maximum CPU frequency.

I read 691 max 160 min but it's not law.

where are the experts
pl guide what is the best minimum and maximum CPU speed that i should set to get maximum performance from wildfire.

It all depends on you and your preferences.
If you're playing games use 729 as max
If you want max battery use 480 as max.
352 is a good minimum overall.

Please find the SetCPU thread under XDA Forums, HTC Dream: G1 > G1 Apps and Games. Or http://forum.xda-developers.com/showthread.php?t=505419
It's an app for you to overclock your wildfire with custom rom. Download the latest one, send it to your phone's SD, install the apk using Astro or other file managers. The app includes On demand, based on how much MHz you currently need. It is free, but you could donate to the producers of the app. I'm now currently running on 710Max/245Low On Demand. Pretty sweet app.

Well Min 480 and Max 729 ... if u want performance!! (M using the same)

[FAST-Guide] Overclocking/Undervolting a tough to OC/UV sgs...

If you are a beginner......DO NOT TRY THIS (Fast-guide)
These are my new "safe" OC/UV/OV settings:
EDIT 7 dec. 2011:
Indeed for those sgs devices that are tough to overclock . a kernel with 6 frequencies is needed
Just noticed another great development:
[KERNEL] MIDNIGHT-/BLN/Voodoo10/UVOC/extendedCWM/...
http://forum.xda-developers.com/showthread.php?t=1199140
Great optimized kernel with many features and 6 frequencies !
Right now for JVT and higher , is the only kernel that I can OC/UV and stable as long as I use these settings:

OC/UV App: Tegrak Overclock Ultimate
Governor: Conservative (but "Ondemand" is doing fine too)
Scheduler: CFQ
Code:
Frequency Core Voltage Internal Voltage
L0 1180 MHz 1310 mV 1110 mV
L1 1000 MHz 1275 mV 1105 mV
L2 800 MHz 1150 mV 1100 mV
L3 400 MHz 1050 mV 1100 mV
L4 200 MHz 850 mV 1000 mV
L5 100 MHz 825 mV 950 mV
Remarks / Tips :
- I use Tegrak Overclock Ultimate app and nothing else, in order to avoid conflicts
- I enphasize, use only one OC/UV app , meaning, uninstall the rest
- In Tegrak I never use the "CPU max frequency" feature , I just load the overclock module and go straight to the " optimization " feature.
Here is a Tegrak guide just in case: https://docs.google.com/document/pub...O4RLIXihSo3yBA
- If your device can handle it and depending on your use, you could try more undervolting and/or no overvolting at all and even more overclocking....BUT...if it will be "healthy" for your device, specially on a long-term, that's another story .....
Because my sgs never handled OV/UV that well ( but it performs great in all other fields), I think these settings are stable for anyone.
But please, report eventual crashes (with these settings, if you do try it)
Ps- I tried it on both file systems (Ext4 and RFS)...in my case, it is more stable when on RFS...
« »

Thanks - will try these setting out later.
Am new to OC/UV, still getting my head around customising my ROM's

That's the spirit, no hurry
Just forgot to mention that the Rom I am using is CriskeloGinger v79*
Adding to first post and also adding a remark about ZRAM (A feature present on TalonDev kernels and its variants)
*Edit: Not using a Cooked rom at this moment, just the stock JVR deodexed/zipaligned and with some mods

New settings update on first post
Adjusted after testing stability using RockPlayer....
Also new versions of Talon SH and TalonDEv kernels are launched

testing these settings now
i'll report back later

ill test it too

OK...only that I stopped testing OC/UV on kernels with 5 frequencies....
So for those sgs devices that are harder to OC, users will need 6 frequencies...
I am very content with the latest Talon SH BIGMEM kernel....highly recommended

BetoNL, nice "fast" guide you have here
Will try soon when I get my phone back to stock
Thanks!

Looks like these settings are quite stable indeed. Not having any problems so far...

[GUIDE] Galaxy S3 CPU/GPU overclocking/undervolting (Updated 12/08/2012)

Only for international s3 variant ​Disclaimer: Im not responsible if something funny happens to your device Read the guide as much as you want before proceeding with overclocking
Overclocking and undervolting is highly debatable, some say its good and some say its bad... so its upto you to proceed further
First rule of overclocking.. Your Mileage May Vary​
Most of the people here in xda do know about overclocking and stuffs but still there are many who are so eager to overclock their beast . Hence this guide.
I have given some good info below about these stuffs as far as i can , you can always use google to get further details.
What is overclocking?
Overclocking is the process of making a computer or component operate faster than the specified clock frequency by the manufacturer by modifying system parameters. One of the most important techniques is running at a higher clock rate (more clock cycles per second; hence the name "overclocking")
Operating voltages may also be changed (increased), which can increase the speed at which operation remains stable.
Advantage:
You can get more performance from your chipset, though s3 is already fast you can see the visible changes in application execution time and much more like instant response time.
Disadvantage:
* Overclocking is always risky if something is configured improperly and may also result in permanent damage of your hardware. As long as it is done safely you are good to go.
* You may see some increased power consumption.
* Extreme overclocking might kill your hardware.
Undervolting :
The process where you provide less voltage to your cpu rather than the stock voltage.
Advantage:
* Reduced heat from your device.
* Good battery life.
Disadvantage:
* Extreme undervolting will make your device unstable and some times even end up with a boot loop.
Dividing the guide into 2 parts CPU and GPU
CPU
The max clock that can be used on our s3 is 1800mhz and the minimum is 100 mhz. Below given is the stock voltage for all clocks for your reference.
1800mhz : 1450mv
1700mhz : 1400mv
1600mhz : 1350mv
1500mhz : 1325mv
1400mhz : 1275mv
1300mhz : 1238mv
1200mhz : 1175mv
1100mhz : 1125mv
1000mhz : 1088mv
900mhz : 1050mv
800mhz : 1000mv
700mhz : 975mv
600mhz : 963mv
500mhz : 938mv
400mhz : 925mv
300mhz : 900mv
200mhz : 900mv
100mhz : 900mv
Requirements:
1. Kernel with overclocking support.
2. ns tools to change frequency/voltage.(you can use the app of your choice here).
3. set cpu and stability test to test the stability of CPU.
4. Some patience.
Step 1:
Set the current clock you want to test via ns tools. (Select max frequency in cpu tab).
Step 2:
Open set cpu's cpu stress test and run it for atleast 10 minutes. If you didnt get any errors on those 10 minutes and the test completed successfully then the clock is ready for daily use
Step 3:
Now for undervolting use the same ns tools and reduce the voltage by -25mv.
Repeat step 2.
you can reduce the voltage further by -25 mv after the completion of stress test until the app become unstable. (Advanced users can try reducing -50mv )
Step 4:
Repeat step 1,2 and 3 for every possible cpu clock you see in ns tools.
Note the stable cpu voltage for every clock, once you finish testing all your clock values save it as a profile in nstools and set it on boot.
Voila !!! now you have finished overclocking/ under voting your beast The very same guide can be used to underclock you cpu.
Notes:
1. Not all chips are capable of running at higher speeds like 1800 mhz. Those speeds are highly experimental.
2. Recomended max overclocking is 1600 mhz.
3. If your device gets hotter allow the device to cool for few minutes before starting the test.
4. Combining the overclocking and undervolting will give you the best of both the worlds
In case of emergency:
1. If your device becomes unstable and not responsive either press the power button until your device restarts or pull out your battery.
2. If you end up with the boot loop due to extreme undervoltage below is the cwm flashable to reset your voltage.

GPU OVERCLOCKING
DIsclaimer :
*** I dunno if any other kernels support the very same overclocking , if it is possible kindly inform me ill update it in the post.
*** Using custom kernel or siyah kernel is purely of your choice, im not held responsible if something goes wrong​
I would say GPU is by far the weakest hardware in s3, its weak in the sense that its using the very same architecture used for galaxy s2 with some additional improvements to clock it higher. Thanks to the head room given, though the maximum clock for our GPU is 440 Mhz we can over clock it to around 700 Mhz which is roughly 70% more than the stock. Yes it is possible. Thanks to our developer "gokhanmoral" who made it possible.
Advantage:
* Games can be made to run more smoother.
* Much smoother UI.
By default stock mali 400 GPU has 4 steppings , its clock frequencies are as follows
160 Mhz - 875 mv
266 Mhz - 900 mv
350 Mhz - 950 mv
440 Mhz - 1025 mv
Once you install siyah you will be having an additional GPU stepping(totally 5) along with the following available frequencies to choose from.
54 Mhz
108 Mhz
160 Mhz
266 Mhz
275 Mhz
300 Mhz
333 Mhz
350 Mhz
440 Mhz
533 Mhz - 1025 mv
600 Mhz - 1050 mv
640 Mhz - 1050 mv
666 Mhz - 1075 mv
700 Mhz - 1100 mv
800 Mhz - xxxx mv
The voltages for the above additional clocks are purely approximated values. So you can either undervolt or overvolt it as per your need.
Sample screenshot of stweaks gpu interface
REQUIREMENTS:
1. Siyah Kernel 1.5 beta 6 or higher
2. Stweaks
3. GLbenchmark 2.5(Egypt Classic and Egypt HD)
4. Basemark ES 2.0 Taiji
5. Nenamark
Testing methods and procedure:
Step 1:
Install siyah kernel and other mentioned apps and get used to stweaks.
Step 2:
Select the gpu frequency in stweaks along with the recommended voltage and apply the settings.
Step 3:
Open the above mentioned benchmark suits and run it.. if you feel any stuttering or artifacts when running the benchmark then you need some more voltage. Exit the suite and increase the voltage in stweaks by + 25 and restart the benchmark.
(** Egypt HD benchmark does stutters with currently all the mobile available in this world as the test is designed to stress the GPU to its maximum.)
Step 4:
Repeat step 2 and 3 if you need underclock/undervolt your GPU.
Notes :
* Though there are many available frequencies to choose from i would recommend not to use 54 and 800 mhz.
* Make your GPU steppings gradual (Eg : 1xx-2xx-3xx-4xx-5xx)
* If you feel your device warm let the device cool before testing.
* You can monitor your gpu frequencies in real time by using a tool called mali gpu status(caution: do not use these apps when benchmarking as it will degrade your result)
* Dont use any onscreen overlay apps like cool tool as it will degrade your benchmark scores.
Some benchmark results :
Below is the result comparison of basemark 2.0 (mobile with hd screens). Stock s3 gpu scores around 38 fps.
Here is the result achieved with max gpu clock of 700 mhz. It simply smashes all the records.

Nice work mate :thumbup::thumbup:

Interesting
Thanks, Bala - though I have tried doing this for my S before, I havent seen the need yet to do this for S3.
Having said that, if you have the right OC, UV combinatons that worked for you - do you mind sharing them. That will be the best use of this thread.

300mhz and 400mhz are not utilized by many kernels so its more or less useless. either 200 or 100 can be used for minimum

It depends on the app its not an strange act, if the app requires a lot of cpu usage it will stay longer on the max frequency, if you dont like that you can always try an lazy cpu scaling governor (controls the behaviour of the cpu)
