Hello there,
I've been flashing kernels since I was in LeeDroid Froyo and got no problems. However since I switched to GB based roms such as RCMix3D and TB Fusion, my phone always freezes when I try setting Kernel-Lee-V3.1.1-2.6.35.13-CALLREC or MDJs v19 to maximum overclock so I have no choice to but to stay on stock kernel. I have no ext3/ext4 partition on my SD card in case you ask.
Current ROM: TB Fusion 1.1.2
Radio: 12.54.60.25U_26.09.04.11_M2
Any idea what should I do to solve this issue?

yes, your handset freezes because the overclock that u do its too high... underclock it at 1200-1400mhz & try...
and configure SET CPU features... like the standby status, etc....but do it with common sense....
think about that DHD proccessor goes by default at 1gz, really when we overclock the processor we are putting in danger the security of our device

Haha! I know that overclocking is quite dangerous. Back on the froyo days, my phone is quite stable around 1.8ghz so I'm just wondering why is this happening (maybe my phone's processor is starting to fry up? ). Is there any effect if I'm using smartass profile on those kernels I've mentioned?

i hope that the processor works or not works (don´t crashes a little bit...)
but the reason of your freezes maybe (almost sure) because froyo & gingerbread don´t works at the same form, and gingerbread need more resources & stability for to work correct... don´t forget that the kernel manages the hardware...
if u force it......... u know what can happen...

it´s possible, take this explanation, read and judge by yourself what´s the better cpu governor...
smartass (Best explanation i've found paraphrases to: based on interactive, but better.)
----
ondemand
Available in most kernels, and the default governor in most kernels. When the CPU load reaches a certain point (see "up threshold" in Advanced Settings), ondemand will rapidly scale the CPU up to meet demand, then gradually scale the CPU down when it isn't needed. - SetCPU website
conservative
Available in some kernels. It is similar to the ondemand governor, but will scale the CPU up more gradually to better fit demand. Conservative provides a less responsive experience than ondemand, but can save battery. - SetCPU website
performance
Available in most kernels. It will keep the CPU running at the "max" set value at all times. This is a bit more efficient than simply setting "max" and "min" to the same value and using ondemand because the system will not waste resources scanning for the CPU load. This governor is recommended for stable benchmarking. - SetCPU website
powersave
Available in some kernels. It will keep the CPU running at the "min" set value at all times. - SetCPU website
userspace
A method for controlling the CPU speed that isn't currently used by SetCPU. For best results, do not use the userspace governor. - SetCPU website
Interactive
The 'interactive' governor has a different approach. Instead of sampling the cpu
at a specified rate, the governor will scale the cpu frequency up when coming
out of idle. When the cpu comes out of idle, a timer is configured to fire
within 1-2 ticks. If the cpu is 100% busy from exiting idle to when the timer
fires then we assume the cpu is underpowered and ramp to MAX speed.
If the cpu was not 100% busy, then the governor evaluates the cpu load over the
last 'min_sample_rate' (default 50000 uS) to determine the cpu speed to ramp down

You have mentioned about those "resources", is there any special measure that I need to do or what? I'm using the smartass profile on those kernels but still *sigh*
Anyway, I've observed on your sig that yours is overclocked @ 1.8ghz even though you're running GB, me envy

you only should do a good over/underclock & set the correct cpu governor for your daily use....
well, you know ho is @MDeeJaay? the developer of MDJ kernels and roms...
he explained smartass with this words:
SMARTASS GOVERNOR - is based on the concept of the interactive governor.
I have always agreed that in theory the way interactive works - by taking over the idle loop - is very attractive. I have never managed to tweak it so it would behave decently in real life. Smartass is a complete rewrite of the code plus more. I think its a success. Performance is on par with the "old" minmax and I think smartass is a bit more responsive. Battery life is hard to quantify precisely but it does spend much more time at the lower frequencies.
Smartass will also cap the max frequency when sleeping to 245Mhz (or if your min frequency is higher than 245 - why?! - it will cap it to your min frequency). Lets take for example the 998/245 kernel, it will sleep at 245.

no, no buddy... i only show the max speed nothing more... i set my cpu concretly like this;
CPU GOVERNOR:interactive
MAX SPEED:1113 MHZ
MIN SPEED:245 MHZ
PROFILE: screen off; 245 MHZ max.
245 MHZ min.
in adition i´m going to modify my syg LOL
haha..thanks again. I'm gonna try playing with the frequencies to see which will suit me
i hope someone can make a stable 1.8ghz kernel without the freeze
IT´S POSSIBLE but i don´t want to try it LOL
i love a lot my DHD
Just installed franco kernel and AOKP and i have some questions
Is recommended to set min CPU to 350 MHz? Is safe to set 350 mhz min cpu with 1350 max cpu and scaling governor: ondemand? I want balanced battery - performance

That is exactly the configuration I have it at. 350min 1350 max with OnDemand. Performance is great, battery life is great. I also have hot plug enabled, which probably accounts a lot for my minimal battery drain with screen off.

Well... you can enable it through the Franco Kernel Updated App link. Otherwise, I think you can enable it through some command in Terminal, but idk how to go about it.
to enable hot plug type su hit enter, allow superuser permissions when it pops up, then copy and paste this into terminal emulator
Code:
echo 1 > /sys/module/dsscomp/parameters/hotplug_enabled
excuse me; have question about this kernel; i couldn't post in the original thread;
by setting the min clock speed to 768MHZ & the max to 1407MHZ, How much voltage does it spend? by setting the min to 245MHZ & max to 1024MHZ how much? i overclocked to 1407MHZ , i saw more smoothness and speed; but i felt that its consuming more power!
is overclocking harmful to CPU? ( always overclocking )

Hi
Political correct answer:
Of course OC "can" harm your device - like all OC´ing
Realistic answer:
Most One V devices can handle OCing up to 1.5 without problems
but since this may be specific to chip manifacturing there is no
guarantee that it is. Therefore before using any OC you should
test it very carefully.
And also - Of course running the chip at higher frequencies needs
more power. Simply physics .)
In "normal" daily use the difference is not big because the cpu will
not run at high frequencies most of the time. If you do things
like "heavy" gaming this is of course forcing the cpu to run faster.
To reduce the "effect" a little bit there is a kernel feature called
Undervolting (UV) with that you can reduce the voltage for
specific frequencies. Like OC this is device specific. So some
devices can run stable with more reduced voltage then others
BTW: why to you set the min frequency to 768?
This will limit that the frequency cannot go lower then that if the
device is idle. Running at 245 needs of course less power then 768
max
Thanks for the nice info, well, i heard that some users said that the best frequency for " My One V" rom:
Minimum: 768MHZ
MAX: 1407
I'm using "Set CPU" to OC
So setting the min frequency to 245MHZ will save more power, right?

Yes - especially for the time before the device can go into
"deep sleep" when beeing idle.
The only "disadvantage" is that depending on the govener that you use
there might be a small lag before the frequency scales up
Actually it depends if you notice it at all
If you use govener ondemand it should be no problem
if you use e.g. smartassV2 you might consider thinking about
using some tunables that will reduce that behaviour.

Thanks, yeah, i meant for normal activities, like checking Facebook,mail, watching movies ... So ondemand mode would be better

What is your recommend governor to integrate with your Titanium-KISS kernel and what is your favourite I/O Scheduler tweaks, for daily use & heavy gaming?
I'm using smartassV2 & i set my I/O Scheduler to deadline until now, because it's peoples favourite
Should i change it to ondemmand to gain a better performance?
Hi
Actually there is already a lot of information about your question
in the KISS kernel thread.
Especially about how to tweak smartassV2 based on "profiles"

Well, I am rooted and on cyanogenmod 10.1..
If I understand corrrctly, you can underclock the device with just an app?
If so, what app can I use (considering its DHD rooted with CyanogenMod 10.1)?

Ace OC tool!

I think the reason I like the Andrev OC Daemon is because you can automate it to use a lower CPU setting when in deep sleep.
For example, when the screen is on, you can set the max CPU to 1.2 MHz, and set it to reduce this to 256 KHz when you lock your phone.
So easy to use, and the battery lasts an incredible duration longer. I've had 0% decrease in battery for the past 2 hours with the phone on, but on standby.
Highly recommended.

Sorry if i misunderstood, but there are performance settings in Settings menu of CM 10.1.So i have set max CPU frequency to 806 MHz and min to 149 MHz and marked "set on boot". Isn't it underclocking ? Off course you can't undervolt the CPU, but he asks just to underclock.

Yes, that would be underclocking, which has shown results in battery improvements. Essentially, you are trading speed for battery life and its all about getting the balance right.
Obviously, when the screen is turned off, and the phone is inactive, you do not need the CPU to hit heights of 806 MHz, which is where Andrev OC Daemon comes in..
You can set it so that the phone uses up to 806 MHz when active, yet not exceed 149 MHz when the screen is inactive.
I have seen VAST improvements in my battery life using this OC/UC tool.
And I really can't over-exaggerate the 'vast' in that sentence..

Hello, i wanna share my experience undervolting.
For people who dont know what undervolting is, its the power or energy that the battery send to the CPU with determinate clock speed.
For example:
384 Mhz is the lowest frequency of our CPU, it has a 800mv volt in the stock ROM with stock kernel.
So in theory, the battery send 800mv to the CPU when it runs at 384 Mhz.
The effect of undervolt the CPU is bassically get more battery life and at the same time reduce the temperature of the phone.Less energy send less battery used and less hot phone in our hands.
How to Undervolt
Im running Stock ROM with Ruby Kernel stable.
For undervolt you need a kernel that support it, you can do it in all rom if the kernel support that.
If you want to Undervolt, i recommend you to use Trickster MOD.
You can Undervolt maybe -50mv all frequencies and see how it goes. Some people can even in best cases undervolt -200 mv. But you need patience to test slowly.
DONT TICK SET AT BOOT IF NOT TESTED.
That why you cant:
For example if you undervolt -100mv and if not stable, and you have set at boot ticked, it will freeze the screen and after reboot it will happen again.
After you set the mv for undervolt, download from play store CPU stability test and run it.
It will test all CPU frequencies to see if it is stable.
If you dont get any SoD, congratulations its stable.
My undervolt settings are -100 or in some cases -75 mv and very stable. My battery temp is 30 C°.
Thank you very much

What is needed to undervolt?
Thanks for the info. What are your battery stats after undervolting? How does it suffer other operations of our mobile like browsing or gaming etc ?
Sent from my LG-E975 using xda app-developers app
You need to first make a backup, install a custom kernel, install trickster mod, and from there apply what this discussion is talking about. Good luck!

Depends on the kernel. I am using Trickster Mod with Viper ZVC kernel. There are other control apps available -- some of them are kernel-specific, some are more universal (Kernel Tuner, Android Tuner, System Tuner, etc.). Look in your kernel's thread -- the developer usually tells which control app(s) to use with it.

Thank you, I'm using AK kernel with UKM and Synapse app from google playstore. Using E-975 (intl.). Can you suggest if I should change the global setting or the individual settings for frequencies ? I had recently (soft) bricked my phone by running benchmark at ~1900mhz CPU and 487mhz GPU (like a villain, I know. Re-connected battery to save it... phew..). I'm really cautious now and I just want it to be less hot and save some battery, that's all. Any guidance would be really appreciated... thanks
