SET Cpu config with Sinyah 2.1 b14! Please...

Hy!!!!! I have the beta version 2.1 14b.....I am testing the SETCPU config in my galaxy.....With my configuration, my phone turn off in 1 hour.....Because? Wich is the problem?
This is my config:
1600Mhz : 1350mv
1400 Mhz : 1250mV
1200 Mhz : 1125mV
1000 Mhz : 1050mV
800 Mhz : 950mV
500 Mhz : 875mV
200 Mhz : 875mV
100 Mhz : 875mV
In Main: MAX 1000000
MIN 100000

Good rom / kernel combo for performance and batterylife

Hi,
After reading many posts about battery draining issues and trying different rom / kernel combo's i would like to share my current settings as they give me great batterylife and really good performance; the UI is still very responsive and smooth.
Also my phone doesn't get as hot at the rear near the camera as it did before...

[ i really like the brightness settings on this rom + the faster screen rotation and the 'search button' mod ]

I hope to hear some of your experiences and ideas about even better combinations in the rom / kernel department...

You forgot to mention that gpu is bumped up to 384 mhz with the uv patch. I also suggest bumping your sleep profile with max freq. to 700mhz. If you look at your for an extra ~100mv you get twice the speed. And this should be set as a higher priority than other profiles.
But here are my undervolts.
1200 mhz = 1128 mv
920 mhz = 952 mv
700 mhz = 867 mv
350 mhz = 757 mv.
My low frequencies are probably lowest theyre going to get. ~36 hours stable on those. I am still bumping my top 2 freq. down but will probably give it more time this weekend because i need the stability at work.

You guys may already be doing this but I'd check each frequency with benchmarks at stock voltage and record values (set min and max to each freq. to lock it to one) and then re-check at the undervolt.
I discovered that even though the phone was stable at some voltages the performance actually started dropping off in tests enough where you could rule out run-run variation. (indicating that although there were no FC/crash/reboot the hardware was not happy)

[Q] What UV-settings works for you?

I'm wondering what UnderVoltage settings people are using, and what settings people experience issues with.
Here's mine:
1400MHz - 1225mV
1200MHz - 1125mV
920MHz - 1000mV
700MHz - 900mV
350MHz - 775mV
This appears (so far) to be stable and battery is (without doubt) noticably more long-lived than with stock ROM.

Running Leankernal.
1200MHz = 1175mV
920MHz = 1050mV
700MHz = 975mV
350MHz = 850mV

[Q]CPU Settings

Hey guys, what CPU settings do you use? And which one would be best for smooth performance?

Min 120 MHz
Max 806 MHz
Smartass noop
(no-frills CPU control)

Smartass2 covernor.
Minimum: 122 Mhz, but I use 200 Mhz
Maximum: 806 MHz, but on some devices, when browsing for example, your phone can hang.
(Nothing works = kernel panic). You then need to lower it. I use 768 Mhz.
For benchmarking, use performance governor. Your CPU will then keep on highest frequency
Hope it helped

Smartass2:
Min 245mhz when sleep mode
Max 806mhz

Mine WS freeze on any frequency above 600 mhz.

Yes these are my preferred settings too.

120mhz minimum

hope this helps!

What are stock voltages? How to see my CPU voltage levels?

Does anyone know what the stock voltages are?
Also, how can I find out what the voltage levels are that are currently set on my phone for each frequency?
It seems like every custom kernel out for our T989's is undervolted by default. I've been seeing some random reboots, and wanted to return to stock voltages, but am having trouble figuring out how to do that on a custom kernel.

I'd like to know this as well.

System Tuner from the market will give you the option to overvolt and tell you the current voltages at all the frequencies. Stock voltages (I believe) are the following:
384Mhz - 800mV
1.02Ghz - 1000mV
1.13Ghz - 1050mV
1.29Ghz - 1125mV
1.51Ghz - 1200mV
1.72Ghz - 1287.5mV
1.83Ghz - 1300mV
I'm interpolating from the voltages I'm currently running, which I believe is 75mV undervolted, so I just added 75mV to the numbers I have and posted the sum. I'll double check later tonight by flashing back to stock and checking my voltages. There are frequencies in between, but those should be good enough for you to determine what the global undervolt on your kernel is.

Okay here's the full list of default voltages. Ignore my previous post.
(Mhz/Ghz) - (mV)
192 - 800
310 - 825
384 - 825
432 - 850
486 - 850
540 - 875
594 - 875
648 - 900
702 - 900
756 - 925
810 - 975
864 - 975
918 - 1000
972 - 1025
1.02 - 1025
1.08 - 1050
1.13 - 1075
1.18 - 1100
1.24 - 1125
1.29 - 1150
1.35 - 1150
1.4 - 1175
1.45 - 1200
1.51 - 1225
1.62 - 1250
1.67 - 1275
1.72 - 1300
1.78 - 1312.5
System tuner will allow you to change the voltages at each frequency or do a global under/overvolt. But make sure your kernel supports UV/OV in the first place, otherwise system tuner won't do diddly squat.

I was wondering what stock voltages are as well just to see how much I have undervolted compared to stock for informational and learning purposes.
I have flashed as many kernel’s as I could try so far that’s compatible with my rom. Those voltages look like Darkside’s Kernel to me. I am not saying those aren’t stock voltages, but I do know that it is possible those are not stock voltages because the stock Kernel would only go to 1.5GHz, anything beyond is an overclock.
Your 75mv underclock could refer to the standard kernel version that is released; however, it could refer to stock but I will flash back to stock to verify this.
If you could post or PM me your currently used undervolted settings I would appreciate it. I would like to collect info and eventually make a graph with what works, what doesn’t and what kernels come with what standard.
I use System Tuner as well, it was well worth my money.

Depending on what version of darkside you're using, you could very well be running stock voltages. Tdj has gone back and forth in using and not using undervolt in his kernels. You are correct in saying that when I recorded these I was in the darkside kernel (hence the voltages listed for overclocked speeds) but I made sure that it was a version running stock voltages and I crossed checked the standard clock speeds with a stock kernel.
Disregard my post where I talked about a 75mV undervolt, those numbers are wrong. My second post has accurate numbers.
And fyi I'm using -112.5mV undervolt capped at 1.35GHz. But it doesn't work at 1.8 GHz (I haven't tested anywhere in between) because undervolting isn't linear.

So that's -112.5mV across the board up to 1.35GHz?
example:
192MHz @ 687.5mV
486MHz @ 737.5mV
756MHz @ 812.5mV
1026MHz @ 912.5mV
1350MHz @ 1037.5mV

It is across the board but with the caveat that 800mV is the minimum. That number is widely accepted to be the lowest you can undervolt without actually worsening the battery life. So your numbers are right except 702 mhz and below are all 800 mV.
