Guys, can you help me out?
Something odd has been happening on my phone. I run Matrix kernel 9.5 on Lazy Governor and everything's fine, but when i turn it to Ondemand the phone starts to reboot randomly.
Does anybody know what can it be?
Thanks!
Try running different min and Max frequencies and see if that helps.

have you fiddled with the voltages
I tried different min and max frequencies and I also played a little bit with voltages. What i realized is that if the voltage is too low for a particular frequency my phone reboots. Do you know how can i teste how far i can get with OC?? If i OC to 1.2GHz for instance, and my phone reboots... Can i put a higher voltage to 1.2 frequency in order to get it working?
Thanks in advance!
Try to increase the voltage as small as possible until it not reboot
But be carefull! Increased voltage can damaged your cpu.
I prefer dont do OC, this device is fast enough on default freq.

My understanding is most people prefer Voltage Control, but SetCPU allows for specific under/overclocking profiles that can increase performance without killing battery life.
If someone could direct me to popular, trusted settings, I'd appreciate it. I'm not a heavy user or power user, so I'm looking for something that just works well. I don't care about benchmarks and things of that nature.
I'm sure this has been discussed, but I was unable to find posts that didn't concern user-specific issues.
Thanks,
Wyatt

That's really all it comes down too...experimenting and finding out what works best on YOUR phone with YOUR configuration...
GOOD LUCK!
ps... have been very stable with OC'd to 1.4
-25 down too 200
-100 on 100
bfq and conservative
I use VControl myself...i like the UI.
For Performance: 100-1.4GHZ (1.5 works too, but is WAY overvolted, and 1.6 is extremely unstable), -100mV from 100-1000 MHZ, -75 for 1.1-1.4GHZ.
For "Battery Life": (i really don't see a difference...) 100-800 MHZ (anything below 800 is painfully slow), -100mV across the board.
I leave schedulers and governors at their stock settings, the only time I change anything is to set the gov. to Performance on Performance for max Quadrant scores.

How many Mhz levels are you selecting? In my experience anything above 5 and it WILL NOT clock up to the higher settings. Maybe thats why you notice no difference in battery life?
For instance if you had say 100, 200, 400, 800, 1000 and 1400 you will reace 1000mhz only
if you had 100, 200, 400, 800, 1400 you would reach the 1400mhz. ive tried many combos and 5 or less was the max it would use (voltage control app, im sure setcpu would most likely be the same)
How many slots does the imnuts kernel support?

I started using SetCPU, and I think I prefer it.
Quick question, it seems like rebooting is unnecessary for the changes to take effect, is that true?
Overclocking definitely worked. I got 1853 @ 1200mhz in Quadrant, up from 1600.
Edit: now 2025 @ 1300mhz / 1300mhv
2nd Edit: Late last night, I was using a stability test in one of the apps, but I can't for the life of me remember which app or how I found it. Now I'm using StabilityTest from the market. What's a safe cpu temp for these phones? I'm getting 32 degrees under full load in an air conditioned environment.

I just switched over to Setcpu as well. It seems to work better for me also. I can now select 6 levels instead of the 5 before in voltage control and I also noticed that the set on boot on voltage control did NOT work but it DOES work in setcpu!! Im happy!
Haven't tried Setcpu yet, but I preferred Pimp my CPU over VC when I was using Miui on the Fascinate.

Hi,
I'm running NSCollab 1.0.50 with franco.kernel from Nov. 13 on a I9020a.
I'm playing around with undervolting the cpu and trying to find the minimum stable voltages. My procedure is to start the voltage as low as the voltage for the frequency step before it and then increase the voltage in 25mV steps until everything is stable. I am using SetCPU to adjust the voltages.
So far this has worked for every frequency step except for the 100MHz step. I can't seem to find the lowest voltage for 100MHz. For example, the 200MHz step will be unstable at 750mV but is stable at 775mV. The 100MHz step is never unstable no matter how low I set the voltage. I can even set it to 0mV (which I know is ridiculous) and it wont freeze.
Does anyone know why the phone doesn't become unstable at ridiculously low voltages for the 100MHz step? I see that the slider to adjust voltages in SetCPU only goes down to 600mV but I can manually type in lower voltage values. Is there some kind of hard-set voltage minimum for the cpu that even SetCPU can't bypass when setting the voltage? Is the phone violating the laws of physics?
Thanks in advance
What's your min frequency in setcpu?
Oh yeah, I should have posted that.
100MHz min
1000MHz max
lazy scaling
i heard that ...
force phone running in low mV MAY damage the CPU and other parts of it and destablize it...
=================================
i have seen some applications that would ignore your input value when it is not logical ...
for example like NS tools , one of them , i don't remember which exactly , perhaps it's live OC, for live OC, if you set value lower then 100 , it would automatically set back to 100 ... i think this may be same as your min frequency case...

The method you are using is wrong. I did the same thing a few days ago, and changing the values like that won't work.
What I found out is that to easily find stable values, in SetCPU put your max as 200MHz and your min at 100MHz. Use ondemand. Keep 200MHz at stock volts and 100MHz try an undervolt.
Apply everything then slide the minimum frequency slider around a bit. I guarantee you 600mv will freeze. Do the same for each value, if testing 200MHz, use 400MHz as your max and 200MHz as your min, stock volts for 400MHz. Slide the minimum frequency left and right.
Sounds weird, but it works. Do this until you find a voltage for each frequency. Then put your frequency max and frequency min at the same value (IE 200MHz) and launch a game or a demanding app and play for a lil while, even if performance suck. Hope it doesn't freeze on you, but if it does, bump the voltage a bit.
If you want good starting values, here's the values I have found that work for me and are 100% stable. No force close over the last few days since I started using those:
100MHz 875mv (75mv under stock)
200MHz 875mv (75mv under stock)
400MHz 900mv (150mv under stock)
800MHz 1125mv (75mv under stock)
1000MHz 1225mv (25mv under stock)
Anyone else that uses VC to OC having a weird issue where it randomly sets the max speed to 800 on its own? Just noticed it today, musta started with the latest update which I believe was yesterday.
I keep the max speed at 800 unless I need more anyways, so I wouldn't notice that. However, when you plug it into your computer, the governor automatically switches to conservative. When you unplug it from your computer, it switches to ondemand. This is only for the computer, not AC.
Voltage Control Extreme works fine for me.

Do you happen to use some battery saver apps like "battery saver", it will throttle your cpu, unless you set default cpu of the app to the max frequency (1000 or 1200).
i aleary set cpu to max 1.8ghz and min 1.6ghz how to st it?? i did try to set it too 1.8mina nd max but my phone hangs and powerd-off!!! how to set it?!
Hey. I wouldnt recommend your current srtup at all unless you want horrible battery life and massive amounts of heat however i sont have an answer for your predicament, try using another app with the same function?

listen to me. set it like I say:
max frequency 1512
min frequency 384
governor interactive
go to profiles and create a new profile. set:
screen off
max 432
min 192
governor conservative
priority 100
this way you have a good performing phone and with screen off a power saving profile. with this configuration I have 15 hours battery (enough for a day) of mid use...with data activated and live wallpaper
Nice stats ! I'm going to try that!

Some phones can handle higher frequency then others if your phone can't go over 1.8 well there is nothing you can do..
Swyped From My Sensation.
I SET IT TO this But anyway i don't care battery life
Dont OC much
dude that's friggin gih frequency's. Dont push it too hard, it'll do no good to the processor. Besides, what do you need that kind of power for ? Runing Crysis ?
I'm pretty new to Android. I got my N5 2 months ago and rooted it as soon as I took it out of the box to get rid of the navigation bar. Didnt install any ROM or kernal.
What I did today was try to overclock it. I wanted to test the performance upgrade with Geekbench 3.
I got 2500. Tried to overclock with this app called: No-frills CPU control. And suddenly I get no higher than 2000...... Tried everything. I'm stuck at a multi core score of 2000 in geekbench while it should be 2500>.
WTF DO I DO? My device is noticeably slower, it's like a GS4 D: I'd rather not install any kernals/Roms
I set the minimum CPU frequency to 300Mhz and max to 2.266Ghz
Hi,
Thermal throttling..., overclocking produces more heat than the stock CPU freq so more thermal throttling. To prevent any damage, the CPU freq decreases according to the CPU temperature...
Let cool down your phone.

Sure, I'll turn it off for a while.
Just to make sure: the standard CPU frequencies are 300Mhz MIN and 2.266Ghz MAX, right?

Yes, that's right 300 Mhz-2,26 Ghz.
Not necessary to turn your phone OFF , when it boots it's a process that causes "heat" at the beginning then you will need to let it cool down again. EDIT: oups, you mean the thermal throttling OFF maybe?
Don't touch it for a while, airplane mode can help. If you are in a "hot" country/weather, air cooling, fridge...
