Desire's CPU throttling

Does HTC DESIRE with stock FROYO use CPU THROTTLING by default or not?
If not the the SetCPU would really come in handy when the Desire is idle.

I too would like to know this.

what do you mean throttling? you mean it drops speed at high temperature? or drops speed when idle?
by default the desire is set ondemand 998mhz when idle or at sleep it drops to 245mhz

this is what I meant.
When you say sleep, does that mean that when the you press the power button once and the screen turns off.
Does this constitute as sleeping and thus lowers the clock to 245MHz?

yes when the screen turns off, unless a program is requesting cpu resources it will drop to 245 not only during screen off but during idle time too
you can improve all this by rooting ofcourse and installing kernel with different schedulers like interactive but ondemand is there in stock froyo

1.
So the stock HTC Froyo just uses 2 states.
When operating the phone it is at ~1GHz, but when the phone is idle it's at 245Mhz.
Correct?
2.
If the scheduler was Interactive but On Demand that would mean that the CPU clock would adapt to my usage. Such as this example:
- If I was browsing the net thru WIFI the clock would be ~1GHz.
- If I was just adding a calendar entry then the clock would probably be < 500 MHz.
Correct?
3.
Are there any slowdowns expected by using the On Demand schedular?

ondemand is in stock
schedulers like interactive, powersave and smartass can be added via root
no on demand also scales the frequencies not just two state
ondemand is good enough only sometimes late to respond to low latency like UI menus, for example interactive is more smart and responds faster there is another called smartass which is supposed to be a further modification
by the way you can notice ondemand sometimes late response while scrolling the default white messages widget in sense

HAMDIR
thx for the thorough explanation.
While browsing through this forum I noticed that the frame of mind is that interactive would give better battery life.
Why is that so?

Hamdir,
Thanks for your explanations Can I just ask you 1 more question. I have asked it on another thread but no-one took the time to give me an answer.
I have installed Richard Trip's svs V5e_1113 kernel but I do not have SetCPU installed. Which governor does this kernel use by default and is there a way (using a command from ADB shell) to use smartass governor instead? I really need to know this.
Thanks and I hope to get an answer this time.

Set CPU question

Good evening guys, hope all is well. I am running unity 2.35 and I am using set CPU for overclocking. The question i have is what is the difference in " on demand, scary, smartass, etc" and what should I have it set on. Thanks in advance!

doesnt unity have a built in overclocking daemon? if i remember correctly the virtuous oc daemon shouldnt be used with any other cpu software.
correct me if im wrong.

Unity has a built in OC daemon, which automagically turns off if it detects an OC app (like SetCPU)
The Built in daemon performs better, and there are apps to make it more user friendly (look for Virtuous OC maybe?)
As for the difference between 'ondemand, scary, smartass' those are different governors, which control how the clock speed is changed.
ondemand increases clock speed when you increase the load, and decreases accordingly.
performance changes up to max speed and stays there.
powersave keeps it as low as possible.
interactive is similiar to ondemand but may provide faster changes.
conservative is opposite to performance, stays at minimum.
smartass is just weird (doesn't have sleep and wake settings I think)
(these were off the top of the head guesses, so don't take it as fact)
I'm currently using interactive which I find is very good, but it's each to their own tastes.
-Nipqer

I use the Virtuous OC Controller and have the wake governor set to ondemand and sleep to conservative. Works great for me... my battery life is awesome. But it's definitely personal preference.

It never fails to shock me how many people flash ROMs without bothering to read the basic information in the ROM thread, or in this case the Virtuous website (which is linked in the top post of the Unity thread):
Virtuous. overclocking daemon will automatically be disabled if an overclocking tools (such as SetCPU or CPU Tuner) is installed. Installing these tools is not advised, as the virtuous_oc daemon responds far more rapidly to screen state changes than any Android (Java) application.

[Q] Daemon controller, what is all this nonsense O.O?!

ok idk ow to overclock correctly i need a way to make this sense 3.5 rom less laggy an run more smoothly, can anybody help me with this???

Yes just use Daemon Controller (basically functions the same as SetCPU) and set your maximum frequency. For most ROMs I would set it around 1.5Ghz, and set the governor to smartass or smartassv2. The governors will depend on the kernel you're using. For a good sense kernel, I would use this one.
Additionally, you can download Incredicontrol via the market and that will enable you to adjust your voltages, based on the frequency steps. A lot of people prefer to bump the voltage up or down 25% to increase performance or reduce battery drain.
I AM NOT RESPONSIBLE FOR ANY PAIN AND SUFFERING YOUR DEVICE MAY INCUR.
If I helped, slap my Thanks button around a bit.

0k the number says 245760 i cant tell which is the 1.5 ghz?

245mhz... That is your lowest frequency. You'll set that as your minimum. Your max should be set at 1497mhz. It'll have some numbers straggling on the end but disregard them. 1497mhz = 1.5Ghz.

KISS-Kernel

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.
max

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"

[Q] Mimicry 1.5.0 Processor Max CPU

When I change the Maximum CPU frequency in Mimicry 1.5.0 it will save but will revert after about 5 or 10 minutes. I want the max to be 1516 MHz because sometimes my phone has issues with Navigation and MAPS and I want to see if this solves it. Am I not understanding this functionality correctly? My CPU governor is set to SMARTASSV2.

You probably installed one of the optional components of Mimicry. I don't remember the name. It overrides the settings in the performance tab and manages the processor directly. Easiest thing is probably to re-run the Mimicry installer and choose the change optional bits route. Lots of details in the Mimicry thread.

Read the OP please. You selected the Virtuous OC Daemon when you installed the ROM. Take note of the last item on the list. If you wish to use your own settings either find a program that lets you modify the Virtuous OC Daemon settings (OC/UV Beater, etc) or uninstall it.
= Virtuous OC Daemon =
– Save battery life and make better use of the kernel CPU frequencies
– Applies a lower ceiling to the max frequency when the screen is off.
– Allows you to change the governor & min/max cpu frequency for screen on/off states (will override anything set in Performance)​

Ahh, for some reason I was thinking that was setting the max for Virtuous Daemon to utilize. Sorry about that, my misunderstanding!
I was hoping to have Virtuous Daemon monitor my CPU (hoping for better battery life) but set the max to a higher amount for the event that it needs it.
