yeah either this is one badass phone or somethings up i have set to 1.6 with voltage as low as it goes then disabled the rest of the ghz settings and ran stability test for 45 min straight no crash ran smooth did get a bit warm i bet it would be really warm with full voltage but i kjnow the voltyage is changing when i set it because you can see it on the stability test speeds do it with full voltage then all the way down and watch it takes longer to complete a cycle with lower voltages

Proofs of my settings
[Samsung Infuse 4G] Entropy512:
You can use SetCPU by itself - Once you install this kernel a new Voltage tab will appear.
[Samsung Infuse 4G] ssfirme:
How are you getting those settings
[Samsung Infuse 4G] JordanED69:
do u get good battery at those settings too?

Edit: got 3610 overall score! damnnn
[Samsung Infuse 4G] jdbeitz:
As soon as I set SetCPU to 1600mhz, my phone froze and I had to reinstall the kernel... some phones just can't handle it. 1400mhz runs great though :)
[Samsung Infuse 4G] MotoMudder77:
With all the talk about under volting so low, I too am curious if it is working. But over clocking is working. I want to try 1800. Or maybe even 2k

Any special steps I need to take to install this on the Stock rooted ROM? I have the modded 3e and green CWM Recovery 2.5.1.2. Thanks!
[Samsung Infuse 4G] Evilspawn:
Damn -200 on every clock speed? Thats seems pretty good.
[Samsung Infuse 4G] common.composer:
So, I uninstalled SETCPU and installed voltage control. Used some recommended settings on here. Still freezing. Then, I checked and there wasn't a init.d folder so I created one and reinstalled the kernel. Went back and set it up again in voltage control, still freezing! Do I need to reinstall VC or is there something else I'm missing?? Running 1.5 smoothly but can't get that elusive 1.6 :(

And is there a recommended CWM for flashing? Red or green?
[Samsung Infuse 4G] VtHondaGuy08:
Not all cpus can handle 1.6 so it could just be your cpu. If its running 1.5ghz fine id leave it at that.
[Samsung Infuse 4G] thomas101:

[Samsung Infuse 4G] speedfreak228:
i know this has probably already been asked and answered, but i running infused 1.5 rom with voodoo enabled. can i just download this kernel and flash with red cwr?
[Samsung Infuse 4G] indymx:
Yes you can
[Samsung Infuse 4G] sn707:
Thanks for a great Kernal!

Running it on the stock rom (Ucke3) and it feels really snappy. Quadrant score is 2079. Flashed using green cwm.
[Samsung Infuse 4G] bedwa:
On the question of voltages holding or not, I'll look into that and let you guys know what I find out. I'm also tweaking the voltages with each kernel to help out with battery power as it is. I'll re-look over my UV code to make sure I've got it setup right....

(in the process of fixing my remote as it is. I seemed to have removed something and made it so that any kernel I compile is 2 MB smaller than previous. I'm re-basing my kernel and readding the files that changed... should have it fixed soon, but it's infuriating as it is.... Urg.....)
[Samsung Infuse 4G] Dani897:
im questioning if uv is actually taking effect. i even made a script to write to the file that configs the voltage to bring it down further, i have it set to -400 @ 1600 mhz, i got tired of playing with it. i may go -500mv tonight just to test the theory. as well as go to -500 at the low freqs and see if i can get it to crash.

has anyone experienced instability only after lowering the voltages?

i did figure out that this phone runs linpack better benchmark than other sgs's getting a 32mflops on multi threaded mode with 27.5-29 being more typical(multi thread allows dual core to be benchmarked according to its ability. each core can only run a single thread so single thread mode would show much lower result on an atrix. it is not a major difference on a single core like ours) and about 28-29 in single thread mode which would only show about 20-24 on a typical sgs at the same speed. that is unless the app update effects the results by a big margin.
[Samsung Infuse 4G] saywhat4118:
Well I used set cpu after I flashed this kernel. Lowered the voltages-300 across all speeds. Then I, just for testing purposes, set the maximum and the minimum on 1600 mhz and ran bunch of tests. Scored really high on quadrant and no errors on stress tests.

my settings are, using set cpu, conservative governor, 1600 mhz max and 100 min. -300 voltages for all speeds. Not sure how much that's helping but hey, I'm getting decent battery life here.

battery life is pretty good. here are some screen shots of my battery usage.
[Samsung Infuse 4G] ookba:
I think you can check your actual voltage settins by running:

# cat /sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table

1600000 1450 1450

1500000 1400 1400

1400000 1350 1350

1300000 1300 1300

1200000 1250 1250

1100000 1250 1250

1000000 1250 1250

900000 1200 1200

800000 1200 1200

600000 1150 1150

400000 1050 1050

200000 950 950

100000 950 950

I'm using SetCpu to set my voltages and it does'nt seem to be changing them...?
[Samsung Infuse 4G] saywhat4118:
I can confirm this. Tried the same thing in android terminal and all the voltages are still stock.

Does this kernel have tunneling support? Trying to run VPN Connections v099 and it just Force Closes. Any ideas?
[Samsung Infuse 4G] lalojamesliz:
Hey guys this is my first post :) I just rooted and installed the infused v1.50 that was on another thread here. The one that says faster then before or something. Well I have never rooted a phone and so far its good but I wanted to overclock my infuse to 1.4 but now I see I should of looked at this thread. Can I download the kernel here or what do I need to download to overclock my infuse 4g? I just got this phone 3 days ago and love it. I am a super noon at this stuff so please help guide me
[Samsung Infuse 4G] crazynfo:
I feel quite certain that 1.0 at least had working UV. I did not open the file mentioned above, but I did fubar my internal sd(corruption, no physical damage). I feel confident UVing caused it, because I had several hardware issues for a day or so, and I managed to get everything back up with gtg's restore to stock & *complete* wipe. My issues were I ran some extreme UV, like -400 on the 100, -125 on 1200 for testing, and I had something like sleep death where the phone didn't go to sleep, and drained the battery that night, the internal sd got corrupted, and the screen was lagging severely on input, and was inaccurate (as in you touch a icon, and it would open the icon above or below) I say the SD was corrupt due to the fact that media scanner would not complete scanning, and hence the apps on it were unaccessible, only apps in phone would show, and when I mounted the internal sd over USB I got drive doesn't exist, wifi adb I would get a file list but couldn't upload anything.

Steps I took to troubleshoot and remedy:

1) Full battery pull reset (ok, but no fix)

2) Reset all settings to stock in SetCPU/Voltage Control (ok, but no fix)

3) Tried reinstalling community kernel 7 (ok, but no fix)

4) Tried full install of infused 1.5, no wipe (ok, but no fix)

5) Tried several resets under red cwm (ok, but no fix)

6) Tried a restore to stock, no pit file (ok, but no fix)

7) Full restore to stock via ODIN, with repartition. Reformatted all SD memory twice prior to starting the ODIN flash. [FIXED]

Phone now acts like she never missed a beat, but I am pretty sure it was (Extreme)UV that caused my symptoms above, because I ran OC alone for 20 hours+ without consequence. And a warning to those new in UV'ing, these problems did not show up until the phone had been using my extreme UV settings for over 8 hours. I thought it was happy with them too, but then with time I think the system got unhappy.

Still a great kernel, and great dev work! I'm still UV'ing and OC'ing, but I'm starting at -100, and working my way down -25 at a time, once every day or two. No problems yet. My problems were the result of extreme settings, just wanted to share my parable of experience.
[Samsung Infuse 4G] bradbusa:
Anyone else noticing extreme battery drain? I lost 20% battery life in 2 hours with the phone sitting in my pocket. I have no widgets or background apps running either. Normally I make it through the day and my battery will have 70% left over at about 6 pm. I started with my uv settings where mikey recommended and then experimented with less voltage. Seems like that's when my battery started sucking wind. Will too much uv cause a battery to drain quicker? I love having the oc ability, but I want to be able to adjust the lower cpu frequencies so I can have good stable battery life when I'm not using it. I had every frequency set as low as VC would allow. :(

On the other hand I did get a pretty good benchmark test @ 1.6ghz
[Samsung Infuse 4G] bradbusa:
For some reason I couldn't add this to the last post.
[Samsung Infuse 4G] bedwa:
Thank you everyone for the info in the last few pages. Looking over my code I noticed an additional line I added and another that I forgot to comment out, thus probably causing the illusion of UV, without actual UV. The voltages (minus the highest settings) are lower than stock voltage. As soon as I fix my remote (jacked it up somehow) I'll get back to coding and fix this. Plus, now Tun support has been added to the to-do list.
[Samsung Infuse 4G] MotoMudder77:
I'm getting great battery life as it is, can't wait to see what we get when UV ia actually working. Keep up the good work.
[Samsung Infuse 4G] Entropy512:
Thanks for the update - does that errata apply to only version 1.5, or also to version 1.0?
[Samsung Infuse 4G] ookba:
Great work, we will wait for your next hotrod kernel! And, yes, tun would rock! :)
[Samsung Infuse 4G] The Jack of Clubs:
i think ive gone crazy. im searching and reading every post but i cant figure this out. i installed the infusion kernel in cwm on the infused 1.5.0 rom, and setcpu now lets me go to 1600mhz no problem, but theres no voltage menu in setcpu. what am i forgetting to do?
[Samsung Infuse 4G] ookba:
Get a newer version of setcpu. I think 2.2.1 is the latest.
[Samsung Infuse 4G] tjy8tim:
but according to the OP, he said there is something wrong with the code so the UV is not actually sticking. so it's useless atm. correct me if i'm wrong :p
[Samsung Infuse 4G] The Jack of Clubs:
ah thanks. appbrain never said there was a newer version. that fixed it for me. set pretty much all voltages to -350 and its still as stable as ever.
[Samsung Infuse 4G] wes78:
I used the CWM zip, but flashed with SGS Kernel Flasher. Everything seemed to go OK, but my Kernel in settings says: 2.6.32.9

Did I do this wrong? Do I need to change to update.zip and use CWM to install from SD?

Do I even need this or am I just bored on a Monday? haha I'm an average user and already on Infused 1.5.0
[Samsung Infuse 4G] ookba:
I believe you are correct. You can probably manually push voltages using a script but careful no to go too low.
[Samsung Infuse 4G] rockburn:
I'm having the same battery drain issue. My phone won't even last 8 hours while I'm at work with minimal to no use. I tried to recalibrate my battery with battery helper, but it made no difference. I'm thinking of flashing the defuse kernel to see if it makes a huge difference.
[Samsung Infuse 4G] motumbo:
I had the same issue first time i flashed this kernel. Then when v1.5 came out i used SGS Kernel Flasher from market and the battery is not draining anymore. I'm also using SetCPU conservative and UV's -100 for all fqs.
[Samsung Infuse 4G] bignate78:
Remember if you just flashed the rom and or kernel to give it a few days to settle, recognize and calibrate itself

If you are using SPAREPARTS with this kernel, I think its best to disable SPAREPARTS.
[Samsung Infuse 4G] bradbusa:
Infusion 1.0 had as good as stock battery life with better cpu performance, when I flashed 1.5 I had worse battery life and great cpu performance. I always flash with red cwm. But it didn't matter how low I put the voltages, my battery died in half a day. I had cpu speeds 900 mhz and below all set as low as they can go with voltage control
[Samsung Infuse 4G] gb96:
1.0 and 1.5 are both effected by the phantom UV values, correct?

Still on 1.0, running with Bionix, can run the phone pretty heavily all day with no worries about battery life. Great stuff, thanks bedwa.
[Samsung Infuse 4G] Entropy512:
Most if not all of our kernels are based off of the original 2.6.32.9 kernel, so will report as such.

Not sure if there's more identifying information available in dmesg...

Does SetCPU now have a voltage tab? If not - you didn't flash this kernel or your copy of SetCPU is old.

If you had read 1-2 pages back, you'd see that it has been discovered that undervolting is broken in 1.5

I think only 1.5 is problematic. Admittedly I don't have too many data points, but on the stock kernel, a day of typical work usage took me to 50%. On Infusion 1.0, I went almost a day of work and wound up at only 79%. With 1.5 - A full day of work took me to 50% again.
[Samsung Infuse 4G] samsungcaptivates:
I have flashed back to 1.0 at 1.4 i also experianced terrible battery drain on 1.5 but 1.4 is still perfect been using twelve hours now and only down to 64 % on my battery level after watching 45 min of ncis and multiple gps runs and messages im loving 1.0
[Samsung Infuse 4G] TehInternetzOozer:
I have been using I997 all day since 8AM with WiFi and screen @ auto brightness all the time ON while listening to Pandora. Battery still has a lot of juice and I didn't experienced any problems. This kernel with Infused 1.5.0 ROM is simply amazing.

I have a HUGE thanks to give out to someone for a sizeable donation. If you would pm me the proper transaction number to compare so I can thank you as well and put you in my insanity crew, it would be appreciated..... ;)
[Samsung Infuse 4G] Dani897:
there does seem to be a voltage issue on v1.5 other than the lack of uv. at times the phone doesn't recognize being hooked to a charger.

other than the charge and uv issue I also noticed that on bootup there was a little garbage on the screen for a split second. the phone ran remarkably well and after a day showed excellent battery life after I changed the governor and clock settings. I flashed back to defused kernel but am looking forward to your next release.
[Samsung Infuse 4G] Ltilt2:
I have been using 1.5 kernel at 1.6 with moderate use, some text, web browsing, few calls and my battery level is 74%. Disconneted from charging at 8:30am and now is 11:30pm
[Samsung Infuse 4G] Entropy512:
That's probably your charger... Which one?

The car charger AT&T sells is awful. It takes 20-30 seconds for the phone to recognize that it's there, and the battery discharges if the screen is on because the charger is so weak.
[Samsung Infuse 4G] ookba:
I can confirm. Sometimes it takes 20 seconds for charger to kick in and the phone to say charging.
[Samsung Infuse 4G] bedwa:
Rages 10-15 seconds for me through a second party charger. My Samsung charger or USB cable is immediate.

Oh, alittle treat for everyone as I'm getting my devbox backup and running, it's the charger sound I use on my phone now....

[Samsung Infuse 4G] bedwa:
how do i set this?

Manually go into the /system/media/audio/ui folder with either adb or a root enabled explorer.
[Samsung Infuse 4G] Ltilt2:
Love the charging sound, thx bedwa...
[Samsung Infuse 4G] Dani897:
im using the samsung charger that came with the phone on the desktop dock(i already broke the charger that came with the dock), it works well with other kernels, but was sporadic with this one
[Samsung Infuse 4G] bedwa:
I reduced the polling of the battery, that's more than likely the issue. Constant polling can use just alittle more juice, but not polling frequently enough will have some chargers not showing as charging as quickly as they actually do. I'll lower the time in the next kernel.
[Samsung Infuse 4G] ookba:
Nice. Sounds likely. I can smell a new kernel cooking!!?? I'm ready to play with UV and OC! :) Oh, and, donation sent. Go have a few beers!

Hey bed what should I.set my.stuff at since uv is broken should I.just leave it as is and use oc? Im looking for balance between perform and bat life any suggestions?
[Samsung Infuse 4G] tjy8tim:
use setupcpu and set profiles. that helps a lot. ran it for ~30hrs before i had to charge.
[Samsung Infuse 4G] tight686:
Looking forward to the new Kernal. Great work!
[Samsung Infuse 4G] tyshemi:
Set profiles?
[Samsung Infuse 4G] tyshemi:
Basicaly what do I put them at I have voltage control doesnt it do same thing and how will I know correct settings?
[Samsung Infuse 4G] bedwa:
I wouldn't use ALL frequencies on the phone. I use all the 200s (2,4,6,8,10,12,14,16) and 1500 frequencies.
[Samsung Infuse 4G] tyshemi:
Can you explain more but do u use set cpu?
[Samsung Infuse 4G] Dani897:
uv doesn't work (for now) so just set up the active clocks and governor. profiles are really only good for heat issues. I don't really see a point in slowing down the phone when the battery is low. its like you know you are killing the battery but don't change the situation till the battery is dead.

if you have instability while charging(heat) then profiles are useful.

as for what clocks to choose I like to have 100 active for sleep and battery life 200 because the difference from 100-400 seems too big but it might not be needed if you use the ondemand governor which would likely never use 200mhz

then from 400 up I like th go every 400mhz.

so mine was 100,200,400,800,1200,1600

in some processor you might have better luck haveing the last few clocks close together, for example my captivate was more stable @1300 if 1200 was also active and the voltage change was small or nonexistent. I had to have 1200 at a little higher voltage than it would need to be without having 1300 active because the voltage changes caused problems. so you may have better luck with the 1500 clock active.

eg. a setup like 100,200,600,1000,1300,1500,1600 might be more stable for some phones

on demand governor sucks batteries, I use conservative but the phone might feel more responsive with ondemand and less clock speed. it is hard to give advice to people because every processor is soo different and usage varries.
[Samsung Infuse 4G] tyshemi:
Thaks buddy ill give her a go
[Samsung Infuse 4G] bradbusa:
So, is it just version 1.5 that suffers from inop undervoltage or is 1.0 not working also?
[Samsung Infuse 4G] bedwa:
Not sure on that one. Can test and advise....
[Samsung Infuse 4G] Entropy512:
I thought UV 1.0 was working (had really good battery life for one day last week), but now I'm not so sure. I reverted to 1.0 and I'm getting "typical" battery life.

I get the impression you've got a lot of changes in mind for the next release, but is there any chance of getting an interim release that just contains the identified undervolt fixes?
[Samsung Infuse 4G] bradbusa:
i had a thought earlier... for those of us who are using voltage control app.. under the advanced tab, if you were to leave certain voltages red (say maybe 900mhz and below) would it revert those frequencies back to stock voltage settings? that would allow us to only modify the voltages for the frequencies we want (1-1.6ghz)

wasnt sure if the app worked that way or not, but figured i'd ask, so we could at least take advantage of stock battery life in lower frequencies as well as the OC feature :)
[Samsung Infuse 4G] Entropy512:
Why would you want less battery life at lower frequencies?
[Samsung Infuse 4G] MikeyMike01:
I believe if they're red they're disabled completely.

Sent from my Infuse 4G
[Samsung Infuse 4G] bradbusa:
oh.. ok. ya thats bad. i was thinking maybe if i left them red that it would apply the factory voltage settings for those frequencies.

i will return to waiting for the next update lol
[Samsung Infuse 4G] tight686:
You can say that again. I refresh at least 10 times a day for the next update lol.
[Samsung Infuse 4G] Ltilt2:
I think everyone is anxious for their fix.
[Samsung Infuse 4G] bradbusa:
no joke, i check in several times a day in hopes for new toys to play with
[Samsung Infuse 4G] Artimus009:
Did something happen to the dl link? I keep getting that its not supported on my infuse....
[Samsung Infuse 4G] ookba:
After more testing, looks like CPU voltages are not changing. You can see current voltages by:

bash-3.2# cat /sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table
1600000 1450 1450
1500000 1400 1400
1400000 1350 1350
1300000 1300 1300
1200000 1250 1250
1100000 1250 1250
1000000 1250 1250
900000 1200 1200
800000 1200 1200
600000 1150 1150
400000 1050 1050
200000 950 950
100000 950 950
bash-3.2#

I tried manually pushing volatges to this file using this script I created (but it didn't work):

echo '1600000 1450 1450' > /sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table
echo '1500000 1400 1400' > /sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table

echo '100000 850 850' > /sys/devices/system/cpu/cpu0/cpufreq/frequency_voltage_table

Seems like setcpu is doing it's job by creating /sys/devices/system/cpu/cpu0/cpufreq/UV_mV_table:

(before setcu)
bash-3.2# cat UV_mV_table
0 0 0 0 0 0 0 0 0 0 0 0 0
bash-3.2#

(after setcpu)
bash-3.2# cat UV_mV_table
50 50 50 50 50 50 100 100 100 100 100 100 100
bash-3.2#

But, it's not taking affect!?

So, we gotta wait for bedwa to get us something new to play with. :)
