If I set the min cpu speed to the minimum (245MHz) using SetCPU and then refresh the CPU monitor, it's always at Max (998MHz).
However if I set the min to 384MHz and refresh, it's at 384 (unless something else is going on in the background in which case it might increase a bit).
This is all with the CPU governor set to on-demand
If I set MAX cpu to 245 then the monitor says it's 254, btw, so it seems it can run at that speed fine and the monitor is working ok apparently. It's just with min speed set to 254, it seem to stick at 998Mhz.
Does anyone else see this behaviour?
It this just a problem with SetCPU, or an underlying issue?
well, having played around with it some more, it seems it's actually the cpu speeding itself up so rapidly when monitoring it that it registers max MHz!
If I increase the up threshold, or the sampling rate, so that it doesn't step up a gear so quickly, then the monitor reads 245MHz.
This does raise the question though that if simply pressing the refresh button is enough to up the cpu to max when it's at the default settings, maybe there are better settings for battery life?
Maybe a slightly higher minimum speed is better, so that it doesn't step up all the time (because when it does, it seems to go straight to max).....
Hi all,
Has anyone tried using SetCPU on his rooted legend? I tried on my non rooted one just too have a look at the CPU frequencies, to see how it behaves at idle and so, and while max is 600MHz the min is "only" 480MHz.
Doesn't that sound a bit high for the min frequency? The snapdragon is clocked at 1GHz and idle is 250Mhz. Has anyone tried lowering the idle frequency on the legend to gain some battery life?
Hi Bricolo_fr,
I found this entry in the FAQ of SetCPU documentation fount here (http://www.pokedev.com/setcpu/):
"Why aren't there more speeds to choose from?
The speeds which the CPU can run at is in part a kernel limitation and in part a hardware limitation. Attempting to set the CPU frequency to anything else won't cause any changes in CPU speed. On some devices, the kernel can be modified to enable certain other frequencies. There are other speeds that would be useful, the capabilities of the processor itself often hinders which frequencies are available on a device."
Anybody has the skills for making a kernel change?or some ideas for us being able to use this properly?
Hi,
Today I rooted my legend and tested again SetCPU. At the begining, it was only possible to set CPU from 480 to 600 mhz, but then I red this in SetCPU documentation:
http://www.pokedev.com/setcpu/
--------------
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. This does not apply to mostly "Google experience" HTC devices such as the T-Mobile G1, the myTouch 3G, any Google development device, or the Nexus One. It does, however, apply to "HTC Sense" devices such as the HTC Hero, Droid Eris, HTC Desire, HTC Incredible, EVO 4G, and myTouch Slide. Non-HTC devices never have perflock enabled.
SetCPU can disable perflock on newer HTC kernels, giving you control of the Max and Min settings of the CPU. To do this, press the Menu button on your device in the Main tab and choose "Disable Perflock." Read through the notice and then press the button in the dialog. If successful, you should be able to change the frequency with SetCPU. If this process fails, please e-mail the developer with your kernel version and device so support can be added.
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.
-------------------
So, in the last version of SetCPU there is an option in the menu called "Perflock Disabler" With this option, it is possible to select the minimun frequence to any value from 0 to 600 Mhz.
I have not been able to modify maximun to a value higher than 600 mhz (overclock) but I think the best target is to reduce battery consumtion decresing the minimun mhz value. Actualy I set minimum 128, maximun 600.
so, are you sure you could set it to the minimum of 128? because i think it doesn't work actually...at least without a modified kernel
I got a min at 19 MHz. to 600 Mhz.

Yes. Also confirmed with the app Os Monitor:
-Saling range: 122880-600000
-Frequency range:19200-600000
-Governor: ondemand
-Current: 122880
Software version: unbranded 1.31.405.4 (just rooted with Monodaco method and applyed all OTA updates)
In SetCPU Info:
-Time in state:
19200: 22
122880: 1169071 (Currently I set minimum at 122880)
128000: 0
245760: 269491
480000: 362472
600000: 347583
SetCPU in Legend allows the following governors: userspace, ondemand, and perfromance. Ondemand works fine. Userspace and performance makes extrage things (i tested quickly, to be honest)
I defined several profiles in SetCPU, depending of battery chage, and seems to work fine. But, I did not enable "Set on boot" option in SetCPU and need to activate "Perflock Disabler" in SetcPU menu everytime I reboot Legend (I prefer to test a SetCPU a few days before enabling "Set on boot")
well...this is nice... after disabling the "perflock" option...
I set the minimum value to 19mhz....lol... with "ondemand" management of the cpu...
I think I'have seen a HUGE improvement of the battery...When I mean HUGE, I really mean HUUUUUGE!
Like, for a 12hours use always with 3g data on,and 2 hours of wireless...lost only 30% of battery...
Testing today for more results...
I use the profile manager in SetCpu to set the CPU to 128-256 while screen off, max mhz while charging, etc.
I have seen big improvements.
Yes, battery improvement is very nice. This solution is great.
I am testing a profile to 122-245 while usb charging. So, when I use Googla Mobile Navigation it is able to load a bit battery while using GPS (normaly drains battery a bit while charging)
out of charge at 6am...it's now 10am...3g ON...wireless ON now for 2hours...
So, in resume, on 4 hours of use the battery loss - 6%
At this rate, and with these settings it should last for about 66hours, about 2,7 days.
Let's see...

I can only say...in 3g mode and with the wireless ON 90% of the time from 6am to 00.00, i had more than 40% battery left at 00.00 when i went to bed.For me it's a new record.

In my case, tested yesterday:
Battery consumption:
battery at 100% at 10:00 am. 3g data on 1 minute every 15 minutes (JuiceDefender), 30 mÃnutes call and 8 emails received and red a long de day. Battery was at 41% at 1:00 am. I spent the day in a place with low 3g network (between 1 and 2 bars in the top right corner)
SetCPU Configuration:
-Profile 1: when battery is between 50% and 100%: min 122 mhz, max 600 mhz
-Profile 2: when battery is between 30% and 50%: min 122 mhz, max 480 mhz
-Profile 3: when battery is between 0% and 30%: min 122 mhz, max 245 mhz
So, battery save is very nice.
this is soooooo interesting....
I couldnt find the app in the market...i found the apk in the HTc Dream forum...version 2.01 by coolbho. Is it ok to use that ?
i think so...
in worst scenario...it won't run lol...(i think!)
If i use linpack i can see someone with a legend that runs on 711mhz? Am i missing something can we overclock..

I've made some profiles too, and it's working really well.
Are you guys using the auto detection of the device? I've used it in the first time, but it detected my device as a Hero(?) since the max frequency was only 528mhz. Then I've changed the device and selected MSM7x27 manually and got the 600mhz max and many middle frequencies like 120, 122 and 128mhz. Now I've changed the device again to auto detection and it worked this time, got the 600mhz max, but less middle frequencies (no 120 or 400mhz). Also, i'm using 122mhz as the minimum frequency in all profiles, isn't 19mhz too low? Or the demand feature really works that well and I will not even notice any difference?
wasup!
19mhz is not too low, i've used it and had a huge increase in battery life.
I am using profiles also at the moment.

Hi,
You can download from this link:

If you like the app, you can donate getting from Maket. Look for "setcpu for root users". It is only 1.99 USD.
Hey Guys. I know there are posts about over clocking and that there are threads like this in the other device forums.. BUT
Now that the new CyanogenMOD CM6.1 is out I was wondering what everyone is doing for their SETCPU profiles.
Can it please be time for us to make a thread like this for the Aria?
To start out, I'm confused about the order of my profiles.
(sorry but i don't have screen capture on the aria yet. anyone have a suggestion on what to use, PM me.)
here is what i currently have going on, highest priority first
100) Temp >50"C = 122"F then.. max 600, min 245, ondemand
75) screen off = max 245, min 245, ondemand
50) charging/full = max 864, min 245, ondemand
40) batt < 10% = max 245, min 245, powersave
30) batt < 25% = max 480, min 245, ondemand
20) batt < 50% = max 600, min 245, ondemand
so my biggest concern is if the temp gets too hot.. scale back to the default max of 600mhz.
if the screen is off then i'm not using my phone so slow the roll
if the batt is full or charging and the screen is on then FULL SPEED AHEAD!!!
if the batt is less than 10%, slow down as much as possible
if the batt is less than 25%, take it easy to conserve power
if the batt is less than 50%, bring it back down to the default max of 600mhz
does that make sense?
Check out "screenshot" by Gik Soft, small and simple, shake to take a screenshot.
Your interpretation of the profiles looks fine to me. For screen off, powersave limits the CPU to the minimum speed anyway, so min=max is redundant.
I noticed quite a bit more battery drain when using profiles (because SetCPU is constantly monitoring your device) but results may vary. Personally, I only boost the CPU for games and documents, and SetCPU will typically bump your phone down to minimum when idle anyway (assuming you don't have intensive background apps running).
I noticed the same, using profiles seems to drain my battery faster. So I just manually toggle my clock speeds. If you set to on demand you dont really even need to worry about a screen off profile. And when my battery starts to get low I just scale down the speed. The only time I've ever come close to needing a temp profile was if overclocked to 825 and using my phone intensively while it was charging...i never go over 806 anymore so temp is never a problem.
I can however see profiles being useful if you keep your phone overclocked to the max all the time.
Hello together,
first of all i would say that im completely new to this rooting and flashing stuff so dont be too hard to me. Lets start with my story: last year ive buyed my wildfire and used it for 2 months without rooting it. fast i've seen that it would be much more easier for me if i start rooting and flashing it with a custom ROM. Wildpuzzle was the first ROM i've ever used on this phone and i didn't updated it for a long time because i thought i can do anything bad to my phone. 3 days ago i've felt very bored so i read myself once again through all of the tutorials and FAQs. I decided to search the forum for a new ROM without sense so i picked CyanogenMod 6.1 because i wanted a stable ROM which dont reboot 4 times a day(like my old Wildpuzzle one). Today I wanted to speed um my phone and read through some posts and found out that I can overclock my wildfire with SetCPU. I've never overclocked a phone or a pc so i dont know what setup is good for it or which is not.
And thats my question: HOW should i do this and with what cpu setup(min/max) for a stable working phone.
PS: as i've read through the overclock posts i've found out that my phone is already flashed with a overclocking kernel(2.6.32.21-HCDRJacob)
PPS: i'm excuse myself for my bad english and hope you all can understand what i mean
Depends on your preferences really. For me, on my SetCPU Normal Profile, I have set it as 614 MHz Max and 245 MHz on Min, Interactive Scaling. Apart from that, I have also set the following profiles:
1: Screen Off - Max 352, Min 245
2: Temp >46C - Max 352 Min 245
3: Battery <20% - Max 480 Min 245
I had set the minimum earlier to 122, while it gave me awesome battery life, the phone would hang whenever I got an incoming call / message (CPU too slow to handle it), hence, after several experiments, I have found it to be stable at 245. For Max, you can keep it upto 710 MHz, but, I wont recommend a speed beyond that for 24x7 usage. For short purposes (like playing a game, benchmarking etc.), you can go till 768, or the max your phone is stable at.
Amazingly my set up is nearly identical to 3xeno but my max in normal profile is 691 MHz

so what is exactly the interactive scaling ??
what is the difference between ondemand, userspace, performance, interactive...
while searching for the answer ... i also saw pple tlking about powersave and conservative scaling ... i dont have these options ... :s
Sorry to butt in but since we are on the subject of overclocking etc and I dont want to make another thread. Is that setcpu app from the market any use on my wildfire? its not rooted.
No you need rout access to change frequencies mate.

Thank you for sharing this information, I changed mine to this too. Can I ask if you 'Set on Boot' on the main profile? I think you would, but I thought i better check!

I usually set my speed to Max 710, Min 480 Ondemand, no profile. I think it's interesting to try your setting. Thanks for sharing.
Does anyone do undervolting here? What kind of settings have you been able to use?
I myself have managed to use the following stable profiles:
I'm using fugumod beta kernel which has different sets of frequencies, in case you're wondering.
Quick guide for anyone wanting to use pimpmycpu
(I offer no warranty if something happens to your phone, but I can assure you, nothing will happen. Worst case scenario is that your phone hangs and you have to reboot it.)
1. Download PimpMyCpu (You must have a kernel that supports undervolting, eg. fugumod)
2. Open it, press on the max MHz frequency you use (for me it is 780mhz, I don't use higher then that)
3. Lower the voltage with 25-50mv steps
- If your phone hangs immediately upon saving, you have reached the max voltage for that frequency and have to use a higher one
- If you succesfully manage to change your voltage, do a stress test or use your phone for a while for eg. gaming
4. When you go to lower MHz (eg. 390MHz) frequencies, I suggest you open SetCPU and from there set the min\max to that frequency. Close and open SetCPU once to see if it hangs. You can also use PimpMyCpu to do this, but I myself use SetCPU. This should be done for all frequencies.
Notice that different phones can get different results, so don't get upset if your phone hangs at voltage X al thought your friend can reach it
Why undervolt?
- It can greatly improve your battery life. Especially if you use a 'screenoff' profile in setcpu. I myself have gained about 10 hours of additional battery life with medium usage.
I ventured into undervolting this week.
The results are simpy amazing. I get about double the battery life, to about 60hrs.
I'm using the standard 2.4b3 kernel with these voltages, from low to high all minus :
125 125 125 150 150
I still need to test more, but haven't taken the time to do it properly. Setting min/max to the same freq is a good tip. Why are you using setcpu for this ? You can do it PMCpu as well, no ?
Your profiles are not displaying though.
Yeah, thanks for pointing that out. Should be displaying now.
And yeah, you can use pimpmycpu for changing frequencies (added that to the guide now) but I personally use setcpu. Mainly cause I have a ScreenOff profile in setcpu for 195 max\156 min and I don't want it to conflict.
After I undervolted my PC for years I just started with my G3. I am using the prereleased FuguMod Ultra Kernel and it's running in conservative profile with 156-1366 MHz.
- for 1366 MHz my deepest working Voltage is -95 (1430 mv).
- for 156 MHz I am currently getting lower and lower. At this time a Stress test with -400 (600 mV) is running (for about 1 minute now).
- When the lowest working Voltage for 156 MHz is found I will analyze one between highest and lowest, and scale all the others equably.
I will post my working settings as soon as I found it.
-400Mv? How did you even get an option to get it that low (Thought PimpMyCpu goes only upto -250Mv. Also for me the stress test in pimpmycpu causes a crash to the program immediately upon trying to use it.
I myself use SmartAss scaling, which seems like a real nice option. Though I'm not entirely sure what's it about.
I'm using 800Mhz with 1125mv, Its stable sofar, but i cant save the Profile, it shows boot settings not saved, when i want to save as boot, It shows Save boot settings? but i cant decide between Yes or No...
can someone help me?

If you do undervolting in the latest version of SetCPU you can undervolt by up to 500 mv.
Alright, as promised here are my final settings. Its running smooth without crashes for two days now.
Code:
freq / mV relative/mV absolute
156 / -500 / 500
195 / -500 / 500
260 / -500 / 550
390 / -500 / 550
780 / -500 / 700
975 / -225 / 1275
1170 / -175 / 1350
1366 / -75 / 1450
While searching for the right Voltages I discovered that the Stresstest in SetCPU almost never made the Phone crash - even on Voltages that were really instable. The Phone mostly crashed right at the moment when I switched into the frequency. So I tested the Voltages by switching into the frequency, out again, in again, and so on. If it didn't crash for about a hundred times, I ran a 20 minute stresstest to be sure.
