Does anyone ever change the min. clock speed?
Well I don't
you don't have to change the minimum frequencies.
i change my maximum clock at 1497MHz & keep my minimum at 245MHz.
try to use Titanium-KISS kernel from Maxwen, dude

I would but I'm on CDMA.
Can someone explain what the schedulers do? I understand the base meaning but I'm wondering what to choose for what?
noop?
deadline?
cfq?
sio?

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
hello, im trying to find any resources what are the voltages for the stock EC05 kernel
i think its 100-1000
but i don't know what the stock Governor and IO scheduler are.
conservative and cfq?

You mean frequencies, yes 100 - 1000 Mhz.
I believe you are correct that the default is conservative and cfq. I am sure someone will correct me if I am wrong. A lot of people like ondemand.
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"

Hello
Can any one tell me what the option in the Performance means?
1- Governor
2- IO Scheduler
3-Set on Boot
and what effect will be on each drop down menu item on the phone when over clocking or under as in attached immages also
I tried to search but failed or might be not searched too good.
Thanks in advance,

They're pretty simple to understand. The governor tab just sets what CPU governor your device will use. The IO scheduler tab just sets which IO scheduler it will use. And the Set on Boot tab is pretty self explanatory. Do some research as to what each specific governor and IO scheduler does and it will make much more sense.
if you spell kernel right people might take you more seriously, just a thought.

Deadline:
Goal is to minimize I/O latency or starvation of a request. The same is achieved by round robin policy to be fair among multiple I/O requests. Five queues are aggressively used to reorder incoming requests.
Advantages:
Nearly a real time scheduler.
Excels in reducing latency of any given single I/O.
Best scheduler for database access and queries.
Bandwidth requirement of a process - what percentage of CPU it needs, is easily calculated.
Like noop, a good scheduler for solid state/flash drives.
Disadvantages:
When system is overloaded, set of processes that may miss deadline is largely unpredictable.
