[Q] [Opinions] Undervolt Settings.

First off, I would like to apologize in advance in case a thread like this exist and I can't find it.. :/ (Search is down, tried Googling) also, if anyone believes this to be in the wrong forum.
ANYWAYS! This is intended to be a preference/opinions thread centering around your OC/UC and Undervolt settings. Feel free to post your current set-up in Voltage Control (or any app of the like) and what Kernel you are running! I wanted to start this to get an idea of what everyone else is setting their UV and CPU clocks to, and possibly give a few of them a try on my own device. :]
Personally all of my clock speeds are at their defaults except for 1000Mhz @ 1200mV. (-75mV). I am also rocking Genocide v1.0 and getting a decent 30hrs of battery life with pretty moderate use.
Post away!

It is kind of pointless since every phone is different so cannot do exactly the same as others. Most can't do 1.4Ghz and most don't wake from sleep at 100 Mhz. All depends what you use your phone for. Mine runs fine at 1.3Ghz except for some TV apps will freeze.

I believe that would be my point however.. curious as to what other people are running as far as cpu and voltage is concerned. Their success and failures. What people can get away with and remain stable. I, and others, could then try their setup (taking precautions of course; ie Nandroid backup.) And see what we get. Who knows, maybe I might adapt a set up that runs better on my device than my current one.

Yes, every phone is different, but that is just more of a reason to collect data - perhaps a baseline can be established, which would be helpful in determining if a particular phone is messed up or just at the low end of the scale. Right now it is hard to determine if a particular phone's troubles are caused by low quality or by damaged hardware.
I keep all voltages at stock, and don't use any OC - my phone runs fine as is, and the battery life actually seemed worse with UV (and my screen felt hot with the screen UV).

My phone wakes from 100 but won't do 1.4ghz for even a couple seconds before reboot but 1.3ghz lasts about 20 minutes before reboot and 1.2ghz is stable. As for undervolts it can handle -25 on 1.2ghz and -50 on 1 and 1.1ghz -50 on 800mhz and that's it otherwise becomes unstable and reboots. Battery life and performance seem to meet at 800mhz with a -50 undervolt games run smooth too and 12 hours of battery. Oddly enough benchmarks are consistantly higher on 1.12ghz than on 1.2ghz I wonder if I'm the only one?

Just to throw it out there. Aggressive undervolts will do more harm than good to your battery life. By that, I mean you'll drain your battery even more.

I can only use Genocide kernel to get 1.3ghz at stock voltage with since all the other choices are uv'd. My last two Epics were able to handle uv'd 1.4ghz by 50mV but I'm not really complaining as I think this is a new phone they gave me and not a refurb. I currently have 100-400 uv'd by 100mV, 600-1000 uv'd by 75mV and 1300 at stock.

My phone can handle 1.4 Ghz but only with the stock voltages. If I try to touch it even by 25mV it locks up.
Who all has enabled the 100Mhz step? I noticed when I did my phone went into Deep Sleep a lot less by a noticeable amount. Staying at 100Mhz a lot.

Always interesting to hear about all this theory behind the reasons for undervolting OC and UC, then to hear about the issues (at times extreme) some have. I would also like to know who uses the 100 step and if it is noticeably better on battery life than the 200? Unfortunately I am missing out on it if I am. Still running Genocide here, but with 1.0 at -50mv 800 @ -50 and 600 @ -25. Very stable and still at 30+ battery life. Having 1.0 down 75 made me nervous. although I hear people dropping it down -100mv successfully.

Good tip about "aggressive UnderVolting"...didn't know that actually drains your battery more. Might explain why 6 hours into my day, my battery is down to 30% already!!! I had it set at 1120Mhz UV to 1175mV (Stock = 1300)...
So now I'm going to try 1200Mhz only UV by 50...see what my battery life is after this!

Can you explain how this is so? Is this based on any actual research, experimentation, or online documentation, or is this just your own opinion?
Unless your undervolt causes the CPU to hang (I've seen mine start to warm up when it's hung, until a battery pull), I don't understand how providing less voltage to the cpu will cause it to drain the battery faster.

If you change the voltage settings please don't blame the rom developers when you phone bricks...

SetCPU Undervolting for Atrix

I understand there are numerous posts in various forums regarding under volting however, none of them relate to the Atrix!
The idea of this thread is to gather enough data that can enable us regular users of the Atrix, to safely and effectively undervolt our CPU's to enable maximum battery life.
I was wondering if you guys and gals would be willing to post what is working for you. I simply lowered mine -75mV for all frequencies on the list in SetCPU and it seems to have given me an extra boost in battery life by about one to two hours.
If you don't have the latest version of SetCPU: buy it off the market or search the forums for it and download it off here.

There's a thread in general from a week ago with some comments on undervolting. Also, in Faux's OC kernel thread there's quite a few posts later on (after he updated it to enable undervolting) with people posting their undervolting tests/settings.
As for me, I just put -50 for all and it's been stable.

People aren't going to waste time searching through the aforementioned posts or threads you've listed. I simply want it easier for people to click on one thread with the specific purpose of undervolting.

Understood, but faux's kernel is thread is pretty active. Also , as obviously see yourself, the other Undervolting thread (which had the same purpose as this one) has already dropped off the radar (aka out of the first page) which will very likely be the same fate as this thread unless you're bumping it yourself every couple hours or it picks up steam. IMO it would have been easier build on the original undervolting thread so there's more info in a singular thread to build momentum on and keep it near the top.

where in SetCPU is the option to undervolt??

Like I mentioned in my original post, search the forums for the latest version of SetCPU or purchase it off the market.

Ive got every frequency at -500 except for 1100. Which i have at -100.

I find it hard to believe that your phone is stable at those undervoltage settings but if that is the case (no random reboots) that's pretty impressive.

I'm betting typo...

You can manually make every frequency to -500 or some other crazy settings, and sometimes it will crash and sometimes not. The thing is, the Tegra2 chip only recognizes and performs less than 100mHz change in-between each step/frequency. So is the different between 2 frequencies is greater than 100, it will still only recognize and use only 100mHz. So even if you are able to set every frequency ridiculously low, the chip is not running at those voltages. Read more about this on Faux123's Kernel thread to understand it fully, I'm just regurgitating it. Hope this helps.

I think I have the newest version of set cpu 2.2.4 and I can't find the volt tab am I missing something is there a setting option I need to enable? I was using faux's kernel with ninja rom

isn't there an issue with faux kernel right now where if you go past -100 it still does -100 not that value you've input (i.e. if you put in -500 its still actually doing -100)

i've been running the following setup, on my second day without charging (only moderate use, gaming for about 45 minutes to an hour and a half plus using my phone as internet browser multiple times throughout the day, 5-6 widgets total. sitting at 18% left, and i'm on hour 30 something)
now, keep in mind this is also using the battery calibration app, ninja speed freak and faux's oc kernel.

i've been averaging around 3000-3200 quadrants in the quadrant standard benchmark test, so needless to say i'm extremely satisfied with my settings.
also have custom profiles set up, if my screen is off i run at 608mhz max, 216 min. charging gets 1100 max 216 min, incall gets 216 max 216 min, battery less than 15% gets 608 max 216 min and battery<10% gets 456 max, 216 min.

Been using these settings for 3 days and I can honestly say they're fantastic. I was getting 11-18 hours out of my Atrix with other ROM/Kernel/CPU settings; with this setup I get 30-40hours. Simply fantastic.
I'm a fairly light user, but I keep data/wifi on at all times (even screen off) syncing 3 exchange accounts (push); make about 10 mins of phone call in a day; surf slashdot/xda/engadget/etc once every hour or two; and watch 5-30mins of flash vids a day.
Only thing to note is that I had to adjust the UV on the lowest setting to -125 to avoid intermittent loss of WiFi connectivity.

Correct from highest to lowest, starting at 1100mhz.
Also, I may have just extended the battery life to 48~ hours last night by using these settings and using a combination of autostarts to stop non-essential processes from starting and titanium backup to freeze non-essential processes that seemed to start anyway.
Also note; when setting up the profiles in setCPU, make sure you get the priorities right; otherwise they can be fairly ineffective.

Overclocking experiences

I figured this is the correct forum since it's related to the overclockable kernels?
Well anyway here's my experiences overclocking the U8800 (with geno's cm7 and oxygen I get similar results)
smartass governor 245MHz-1516Mhz
-----------------------------------------
About 2400 on Quadrant standard after a few runs. Stable (I don't remember any reboots atleast
ondemand governor 245Mhz-1516Mhz
------------------------------------------
About 3000 on Quadrant standard after a few runs sometimes, sometimes it won't get higher than 2800. Some freezes / reboots.
interactive governor
-----------------------
The strange thing is that the phone freezes if set the max. clock >1100Mhz with this governor. The phone runs fine for atleast ~5mins (haven't tested it for longer periods) even with the performance governor and max. clock 1516Mhz. (max. clock all the time). Anyway with interactive 245-1100 I get about 2400 in Quadrant if I remember correctly.
Anyone else been testing different OC settings? The strange thing with smartass is that you don't seem to get max. performance with it (3000 quadrant with ondemand vs. 2400 quadrant with smartass). I know there's a lot of stuff happening in the background which causes different results, but the difference is big. Could it be that smartass is is not giving max. performance because the temp is rising too fast or something? But on the other hand the score never is higher than 2400 even if the battery temp is 20C or something.
Also the interactive governor freezing if max. clock is above 1100Mhz is strange.
Oh yeah and the highest battery temp I've had is 41C, after which the phone froze (ondemand 245-1516).

Well I can say my highest temp I reached was ondemand 245-1516 is 39 degree celsius feels nice to hold it great heat warmer at winter !

Quadrant is poop, you should use AnTuTu.
I'm using Oxygen with franco.Kernel+ZRAM and overclocked to 1,8GHz, governor is SavagedZen. Here is what I got:
Quadrant: 3533
AnTuTu: 4327
Attached screenshot of Quadrant but forgot to take screenshot off AnTuTu But I fortunately submitted that score, so you can check it with the AnTuTu app if you don't believe.

Looks like smartass has similar score drops on antutu compared to ondemand. So I'll just keep it ondemand and 245-1500 for the moment. When the new kernel is released I'll try 1800

I'm running the latest (110811) Oxygen with its own kernel. 3300'ish points from Antutu and 2400'ish from Quadrant. Seems pretty standard. Gonna also try 1800 when franco gives us update.
EDIT: And clocks were 1516 Mhz and ondeman governor. Smartass gives a lot smaller results for me too. Only about 1800 in quadrant with smartass

Have you had any freezes/reboots with ondemand 1516? I had quite a few and then changed back to smartass. The temp was around 37C so that shouldn't have been a problem. I haven't tried ondemand on the newest oxygen so it might work better now. It might have been the 2g/3g freeze with the earlier oxygen.

Yeah it freezes randomly. I did 3 runs on antutu and 2 runs of Quadrant succesfully and then left my phone on a table. After a little while the phone rebooted itself. So it rebooted when it at least should have been running 245Mhz. I didn't check my battery temperatures but it didn't feel even warm in hand when reboot happened.
Btw, I accidently thanked you for the message when I tried to quote.

Atrix Kernel

Hello,
I'm running Ba2tf CM7 with the stock kernel and I was wondering if faux123's enhanced stock kernel 1.0ghz would be better in terms of battery life? I know that with the stock cm7 kernel you can't undervolt so would faux123's kernel allow me to unvdervolt a bit and still keep the phone at 1Ghz so the battery life would better?
Thanks in advanced.

I use that kernel, and you will get better battery life if you UV a wee bit.

I use this kernel also and am undervolted and get pretty good batt life. Ive tried them all and get the best from the enhanced 1.0 here are my settings

i blve its the third tab over it says voltage

The difference in battery life between the 2 kernels is ever so slight, Faux beating out the CM7 by just a hair

Can anyone point me to where I can find this kernel?

thanks
thanks for yours answers!

I am running the same rom, and when i flash the bootloader, the phone boots and about 10 seconds into it gets very hot and locks up. Any suggestions. Thanks.

Im not an expert but it sounds like your phone does not like the custom kernel.
Is it a refurbished Atrix?

Don't think so, but don't know for sure. Just bought it from stumpyz964. Ill just try another. Thanks.

300-725
400-775
500-800
600-825
700-850
800-875
900-900
1000-950
1100-975
1200-1025
1300-1075
1400-1125
are the most extreme voltages possible, nobody has been able to go under
i have studied these voltages with fenomeno83

Tried your undervolt and it gives random restarts. Sometimes its okay but other times it just locks up within a few minutes. Just wondering if you have revised those voltages yet to become more stable?
Thanks

these settings vary from one device to another. Those, for example, perfectly worked for me but locked up my friend's device constantly (same ROM, same config).
you need to try and find the best config for your own device.

those are extreme voltages for s3, you device not support them, up all of 25mv, if still unstable, up 50

I'm looking to find out how far UVs can be taken on the S3. Please vote in my poll:

Useless, lowest voltage are mine, stop.

Just testing other other people's UVs as I've been doing some of my own. Seeing if extreme UV was true and stable but it wasn't for my device (was confirmed working for 3 people by the looks of it).
I've managed to get mine running on these voltages with 200-1200mhz not fully stable yet but usable. Still working on it for full stabilty.
200 - 695
300 - 695
400 - 707
500 - 783
600 - 807
700 - 840
800 - 855
900 - 890
1000 - 927
1100 - 985
1200 - 1000

absolutely impossible that your are stable, the totally stable:
-100mv for all freq, like the next phenomenal extreme
then: echo "800000 825000 900000 950000" > /sys/class/misc/gpu_voltage_control/gpu_control

I have to agree. And I've messed around with voltages often enough to know that it simply isn't worth the hassle of trying to find the right voltages to suit ur device as u gain next to nothing in terms of battery life and heat reduction.
"Mine is bigger than yours " springs to mind

Holy ****! That's an epic undervolt. I'm amazed at how much UV the higher over clocked frequencies can handle.
