hi all i have set my s2 uv values to very agressive values is it safe or not ?
and my phone never craches " crash once i change the shed. from bfq to noop "
i am using the latest seyah kernel 2.6.11
100 ---- 825
200 ---- 825
500 ---- 875
800 ---- 950
1000 --- 1050
1200 --- 1150
is it safe or not ?
and i use set cpu with voltage control cau voltage control "free" doesnt have screen of profile
and any one can recomend the best shed. for my config.
bfq or sio or cfq
Bfq or sio with Siyah 2.6.11, take your pick (I prefer sio).
So far as undervolting goes, shouldn't cause you any problems so far as reducing the life of the phone's components go. Obviously if you go too far with it you'll have instability/crashes but it shouldn't harm the phone long-term.

Yeah. Undervolting does not harm the device. Overvolting and sometimes overclocking however does.

Looks neat. I would try it but I am a complete noob at kernel clocking and voltage. Is there a guide for N1 volt changing?
I would give a try... looks nice GUI... emmm... does this same like SS4N1?

It's a lot of trial and error, you have to find the lowest voltages you can while still being stable and its different for all phones. Here is an example of a HAVS table that is stable on about 50% of dIncs (which share the same processor with the n1, so I'm guessing your voltages may be similar)
128000 850 875
245000 850 875
384000 875 900
422400 875 950
460800 875 975
499200 875 975

You can use these as a starting point. They may or may not be stable for you. If you're running an SVS kernel (only one set of voltages comes up when you start the app, use the voltages on the right of the table.

I'm unfamiliar with ss4n1, but this is an app that is used to adjust cpu voltages so that you may under or overvolt the cpu.

HAVS voltage checking. Minimum voltages can no longer be set higher than maximum voltages.
Boot voltages are now stored in the application’s data directory. Boot settings will now persist if you update your ROM or restore the application and data from a backup.
I'm new to undervolting background. I remember reading about havs before but forget most of what it is. .. . . .can I ask when setting the voltages what is the correspondance of havs voltage to normal voltage? It appears to be higher by most ppl, is there a set amount which it should be higher than original undervolt per frequency?

Most generally set the voltages lower than whatever undervolt is provided by the kernel. It takes a lot of trial and error to get the voltages as low as possible while still being stable. If you look above I posted an example table that you may use as a starting guide.

Thanks. I just realised my kernal doesn't support havs so its tab/settings are irrelvant anyway XD But I used your table but then found another table in a thread for a kernal for my phone with voltages much lower again and I adopted those values without any stability problems so far
EDiT:My second question has been answeres . .read changelog now that I kno I can restore my custom Voltage table through titanium backup this is now one my my favourite utilities
Wait . . .just realised that 'set on boot' isn't working for me :/
When I apply changes and click set on boot and restart my changes are lost and voltages are back to default! it does say 'boot settings found' though
And another question on a related note, let's say voltage at 122 is 800mv. . . .and voltage at 192 is also 800mv. Does this mean the battery drainage of running at 122 and 192 is identical?
(Because if this is the case it would mean by always setting the minumun frequencies at the highest voltage of a certain mv range you get the same battery drain but tasks get done faster so its being drained for less time . . .saving battery?)

Are you clicking set on boot and then clicking apply afterwards? You must check the box and then click apply. Try restoring defaults and trying again.
Also, a higher frequency running at the same voltage will draw more power than a lower frequency at the same voltage. While the voltage is the same, the current draw at a higher frequency is more = more drain.

The first two values in incredicontrol are a digit shorter than the rest, what are these for?
Are these the pm mode cpu freq values? Or should der be a 0 at the end.

Looks like the kernel dev made those frequencies usable. If you utilize them then you can adjust the voltages. If you don't use them then you can leave them. What kernel?

Ah ok, in that case because the frequency is so much lower I should be able to put the voltage wayyyy down am I right? Its already undervolted by about -50)

In theory you should be able to go pretty low on them. But it only matters if you actually use those frequencies. What is your minimum frequency set at?

Well I'm not using them atm because I was afraid they would cause instability on wake mode and in sleep mode I taught they would keep the phone out of om state for longer than what was worth the battery saving.
At the moment the minimum frequency for both screen on and screen on is 122880 @775mv

u shouldnt be doing that.
ever wonder why nofrills cpu control doesnt include cpu freq/governor changing based on profile? because the author stated that those changing should be done natively by the cpu governor, not by the phone itself.
and smartassv2 already include max cpu freq on screen off profile and for my kernel i already set it to 320. same as ondemandx, savagedzen, interactivex and smartass, i already set screen off max at 320.

I'm getting what your point is. But, I have several questions:
1) Why that guy developed an application -No-Frills CPU Control when all the features he presented where available under Settings > CyanogenMod Settings > Performance?
(And then he said "you might need a custom ROM like CyanogenMod", if he didn't give profile feature)
2) When I go to /sys/devices/system/cpu/cpu0/cpufreq/smartass I can't read any of its set frequencies.
3) And how come SetCPU is any different then switching the governor manually? Standard procedure also changes the governor as SetCPU does. So how come it is harmful? Just because SetCPU might switch profile too often?
I used SetCPU just to save more battery. I'll disable SetCPU and observe CPUSpy stats and let you know about freqs switching.
No Frills works on a stock ROM dude, he said you might need to use CM because maybe he's afraid stock kernel has a freqlock thingy.

Linux kernel governor, hmmm I dont care on these. I use default ondemand, and burnout battery that I dont care, as long as i can see elctricity terminal or I have to use 60Ah car battery in my back hhhhhh.
I didnt use my ace on scientific processing, connecting thousand of android doing parallel processing looking for alien. So 8 hours battery is enough for me.
Peace
As title says, what is the best setting to be chosen?kindly brief the detail coz im newbie
Sent from my SK17i using XDA
Well it depends on taste and kernel support but for me the best will be interactivex as governor and sio as I/o scheduler, it gives you no lags and good battery life.
i installed x kernel v4, did not have to change the cpu governor or i/o.
i only install nofrills to do benchmark, then removed it afterwards.
best battery life ever on hybrom v16
i think it uses ondemand for cpu, not sure wether it uses noop or deadline for i/o
i am currently testing smartassV2 cpu governor with simple i/o scheduler on krsh3 kernel
so far battery time is better with these settings than the default ondemand governor

how about the battery performance ?
Hey
After I rooted (and reflashed) my Z5C, I noticed that the battery was draining very quickly. Then I found out that it had been running on max frequency w/ the performance governor. So I wanted to ask if anyone knows the default/stock frequency, governor and scheduler? And for some reason it sets itself to performance and on the highest frequency so I have to set it manually apparently...
Kernel auditor can possibly help
