Just ran Smartbench 2011 and the result was on-par ... 1211/2775.

maybe ill try to reinstall 2010 ... just a thought. Not leaving Frozen any time soon. Love this ROM.

I don't do the whole smartbench stuff I just go off feel when it comes to roms n such.

However I must say my phone at 1400 is about as fast as my laptop! It is ridiculous how fast it is! So far I have everything undervolted to -50 till I c how she runs.

Great job on the kernal. All I can say is WOW!

[Epic 4G Android Development] tpike:
im curious if anyone has seen freezes at 1.4 with stock voltage and found a way to make it work with UV? seems like a lot of folks are having success with 1.4 but im not, guess thats what you get when you get a phone on release date :)

also, i found it helpful to run cpu spy to ensure my settings were actually saved and being used. ive noticed others saying the same thing. with .4a and setcpu i would check the info tab occasionally to ensure i was spending some time in 1.2. there were times i had to move the slider to 1.0 then back before it would take effect. anyway, hopefully some helpful comments.
[Epic 4G Android Development] Skidiver:
Can you please help me to understand voltage control because I have tried yours and everybody else's posted in here and my phone still freezes up... I will appreciate your help!!! I read ROD post already but for some reason I cannot figure it out!!!

Thanks

Anyone having some serious battery drain?
[Epic 4G Android Development] vocaltreat:
As far as my scores I'm usung smartbench 2010 and always get around the same....high 1600s/3700s....linpack 19.....I'm using synergy rom and I cant go over -25 for unervolt but thats just my phone....and yes its faster then my laptop too lol...ill try 2011 just for giggles soon. Remember every phone has a different personality for some reason...mine can handle more in some areas.....my batt as far as drainage has not been a problem...remeber also when undervolting to try one at a time for a while to see how stable ur phone is before moving on....I read one of u guys had freezing issues....don't go by what others have as settings for my above said reason ;-)
[Epic 4G Android Development] Mk4UmHa:
How do I know that genocide is installed? I don't see it under phone info.
[Epic 4G Android Development] Rodderik:
download and open terminal from the market. then type:

cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies

and you should see something like

$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
1400000 1300000 1200000 1120000 1000000 800000 600000 400000 200000 100000

that will show you the available frequencies thus letting you know it is indeed installed....if you flashed then more likely it installed fine...there is no special branding or anything in the kernel that will show up in about phone
[Epic 4G Android Development] Rodderik:
for those of you that want to drop to 100mhz...voltage control doesn't set minumin frequency. but we can do it with one command from a terminal emulator or 'adb shell'. by default the kernel has 200 set as min and in order for it to work you must issue the command below AND have 100mhz enabled in states. just be warned running 100mhz could give you a higher chance of the phone not waking from sleep but it could be just fine too...just depends on your phone

To set 100mhz as minimum frequency type this in a terminal:

echo "100000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
[Epic 4G Android Development] jbadboy2007:
I figured out how to get it to scale to 100mhz. Just check 1120mhz state but tou can still use max clock of 1000mhz and it will scale down to 100mhz properly.
[Epic 4G Android Development] musclehead84:
Love the kernel. to bad my phone cant handle 1.4 though. 1.3 is really fast though.
[Epic 4G Android Development] tony45x220:
I'm a little confused on the link for the 100mHz conservative gov fix....I looked around the site a lil bit and I don't see anything but the C++ code, am I missing something obvious...?
[Epic 4G Android Development] :
Awesome Work Rodd. You're truly a genius.
[Epic 4G Android Development] brickwall99:
Without using SetCPU how can we duplicate the ability to set the Min/Max CPU speeds when the screen is off?

Rodd, great work on this Kernel! I think it's the best so far.

Would you be willing to change the Kernel so we can try 1.5ghz, but without increasing the voltages any higher? As in 1375 mV?

I think some of our phones would be able to do it. But this way you don't increase the voltages any higher.
[Epic 4G Android Development] Mk4UmHa:
I've been trying to connect to my phone using "adb shell" but it keeps telling me that the device isn't found. not only that, my network keeps disconnecting every time I plug it in. I'm running linux as my adb debugger. It somehow keeps thinking that the phone is my new network even though I don't have USB Tether running.

Bus 002 Device 005: ID 04e8:6881 Samsung Electronics Co., Ltd

Any Idea on how i can fix that and whether it's a kernel problem, I did start off with ACS 1.1, then flashed it over with VisionKernal 1.1, and now Genocyde. I wonder if that's an issue flashing over multiple kernels.

USB debugging is also enabled but the OS keeps trying to use the USB as a wired tethering network port so I can't use ADB commands on it.
[Epic 4G Android Development] Rodderik:
the profiles are part of setcpu and require it be running to work as far as i know.

i'm not going to push past 1.4 even w/o increasing the voltage but my sources are freely downloadable from github and can be compiled if some one else wants to try it but it is my opinion that you wont get 1.5 or 1.6ghz w/o bumping the voltage up quite a bit more which is already above recommended voltage. it just isnt worth my time/hardware to persue any higher at this point. i can promise you that a real 1.5ghz overclock will not work without bumping the voltage.
[Epic 4G Android Development] greatlakesghost:
You can also use android system info, free on the market. Click on system the cpu and it will show all the increments and percent on those increments. It used to show it under the os in it too but this one doesnt. A little easier to check it out than terminal imo.

[Epic 4G Android Development] brickwall99:
Damn. Would you mind giving me a little details on that please? Are the processors in our phones significantly different than what a modern desktop has? Such as, do they actually require more volts to scale to a higher CPU speed?

(I'm sure you know this, I'm not trying to educate you.) On a desktop you can push the CPU faster as long as it's stable, you only have to increase the voltage if it's unstable. And it doesn't require more voltage to actually run at the higher speed.

So far it seems like my phone is doing ok on -50 mV at 1400, maybe even less, still testing. I am thinking I could get away with 1500 at 1275mV or maybe less, I just need to be able to try it.

Are our phones different?

Thanks for the quick reply!
[Epic 4G Android Development] Rodderik:
you said "you only have to increase the voltage if it's unstable." 1.5 will not be stable at at 1.3 volts...period...all the sources ive seen that push 1.5 or 1.6ghz have all had their voltages push over 1.4volts and i'm not going to push my phone anymore past the recommended voltage than i already have with this kernel

with all due respect i'm not gonna get into this anymore in my thread since i've stated it pretty clear that i wasn't in my OP...if you feel like doing it then you are more than welcome to grab the sources and do it yourself

also the higher the clock speeds you start to introduce the 'bullet time' effect with out changing a LOT of other values besides just the core clock speed so benchmarks will report better scores but the absolute second is stretched longer...you can see this by the clock skewing after a while

[Epic 4G Android Development] jspsuperman:
Is anyone elses phone getting very hot when oc to 1.1 or 1.2? It scared me so i reverted back to rods .5 update. Im just stock w root. Can anyone tell me what temp is to high? I saw a maximum of 109 degrees f with lite use. :( Not to mention the crazy battery drain. And when the phone was on the charger it was draining battery like a beast to.
[Epic 4G Android Development] roghaj:
My setup and the reason

I have:

200 UV100

400 UV100

800 UV75

1200 UV50

The reason to have fewer frequency enabled it to reduce time spent switching. In other words, when you need 1200mhz, the phone will take less time to get there. It only needs to step up three times. Less steps is better. You will notice that you spend most of your time at 200mhz. The 1200 mhz will be used when it needs to, but will get its stuff done, then drop you back down to 200 faster again. Am I right or what?

I may remove 400 or 800, we'll see how it goes.
[Epic 4G Android Development] apatcas:
You might have some problems throttling if you do that.
[Epic 4G Android Development] XxLostSoulxX:
So do i really need to undervolt or can i just flash and go away with 1.4GHz?
[Epic 4G Android Development] roghaj:
The only thing I'm worried about is increasing my time at the higher clock frequencys. If that happens, my battery will just die faster. Faster than what?... not faster than stock, I'd bet on that.
[Epic 4G Android Development] Rodderik:
you dont have to undervolt
[Epic 4G Android Development] XxLostSoulxX:
Is it possible if you can put a preset undervolt for the frequencies
[Epic 4G Android Development] Rodderik:
i'm going to take a much needed vacation in the woods...ill be back sunday

[Epic 4G Android Development] JohnCorleone:
Have a good one. Thanks for the fantastic kernel!
[Epic 4G Android Development] XxLostSoulxX:
One thing iv'e noticed is that this kernel heats up real quick compared to Vision Kernel or Twilight i mean cool stuff but after setting to 1400/1400 phone went from like 79/80* F to 91/93.2* F in the matter of 15 seconds.

I literally just checked phone it said 87*F and went to gallery looked at 1 pic and went to desktop and phone is at 93*F?

However i have to say you said the framerate has been changed to 72 from 60, well i only hit 56FPS. there must be a problem with voodoo. Because on Vision kernel its supposed to be 72 or 75 but hits 65 because of voodoo as well. Now on vision kernel 1.1 they reverted it to 56 so it would get rid of video issues.
[Epic 4G Android Development] k0nane:
Yeah... That's because it's running at 1.4ghz all the time. Don't do that. Normally, your phone will spend most of its time at 200mhz.
[Epic 4G Android Development] XxLostSoulxX:
Well yeah but i also just edited my post because its now on conservative at 1120/100 and phone was at 87*F and went to gallery for 10 secs and came back to desktop and phone was already at 93*F. seems a bit much just for a few secs as well as its not on performance mode nor @1.4GHZ
[Epic 4G Android Development] k0nane:
Don't worry too much about temperatures - unless they exceed ~35C at idle, you're fine. Don't even bother looking at Fahrenheit temperatures, they're pointless for CPU temps.
[Epic 4G Android Development] JohnCorleone:
Thanks for this info. I was wondering what was the Max temp to watch out for
[Epic 4G Android Development] XxLostSoulxX:
well earlier i was on twilight 1.1.0 and phone was just on ondemand @ 1GHz, and it was charging and was at 101-103*F. I know you say dont worry about it but when my hand is hot because of the phone thats a bit extreme. i prefer the phone to be around 75-86*F. Because heat affects the cpu and overall performance of life on it.

By the way the phone screen was off for a good 10 mins so its not like i was playing with it as well as it was charging.
[Epic 4G Android Development] thomasskull666:
The phone will automatically shut off far before the cpu is going to fry. Also, charging is going to increase the temperature of the BATTERY, not the cpu.
[Epic 4G Android Development] JohnCorleone:
More good stuff. Just learned something new in the last 2 posts. Had no idea the phone would automatically shut down.
[Epic 4G Android Development] XxLostSoulxX:
Nevermind thats what i meant is the actualy battery not the cpu. But still the battery gets way too hot.
[Epic 4G Android Development] XxLostSoulxX:
Also just installed Vision kernel 1.1 and its on charge phone froze and the battery seems more than 85*F.
[Epic 4G Android Development] JohnCorleone:
If you are at 1.4, maybe you have a phone that can't handle it. A lot of people can't go above 1.3 and some can't go over 1.2

I also notice sometimes I have to set Voltage controll several times for it to take, but otherwise it is a great apk
[Epic 4G Android Development] roghaj:
So I set the phone to only run at 1200, and stepped up the uv until it failed. I got it up to 75 stable. Did the same for 200 and 800

800 100

200 150

Can't wait to see my battery life tomorrow.
[Epic 4G Android Development] b15love:
same here! I was going crazy playing with UV, and just recently tried -25 at 1400 (also not using 200) and it seems to run good with no crashes so far! so happy since Vision at 1.4 would lock with 5 secs..

EDIT: after some torture test it finally froze..
[Epic 4G Android Development] b15love:
also for those running this kernel perfectly without UV try GLBenchmark, its free on its site, just register so you can see your FPS
[Epic 4G Android Development] XxLostSoulxX:
Actually no becasue i ran Vision kernel which i ran @1.4GHz no problem just a few issues regarding the concern of me doing something and a few freezes but i can probably run higher lol. If its possible i would like to see if it could handle 1.41-1.45Ghz.

EDIT: i know 1.5GHz will be the end and wont even boot as well as admitting way too much heat. But i will do a test to see how long my phone under ONDEMAND at full blast 1300/1300 can go then i will do 1400/1400 after.

[Epic 4G Android Development] lv2bll:
Tanks Rodd, this kernel along with the voltage control app is an epic win for this community. I hope ever kernel can be set up to run this way as im having 0 scaling issues with undervolt working perfectly between all frquencies. Thank you soo much for this as this kernel is the first to play nice with my epic. When i get paid you will see a donation fro this great work. Also thanks to everyone who helped him with this!!!!
[Epic 4G Android Development] 1greek4u:
Ok so I made this post prematurely. I had no problems benchmarking each of these frequencies individually, but I couldn't get all the steps working simultaneously without the phone crashing. I just don't understand. I tried halving the undervolt on each of the steps but still the same thing. I guess I'll have to work at it tomorrow.

-------------------------------------------------------------------------------------

Just spent three hours setting up all my frequencies and undervolts. These are my EXCELLENT results:

200mhz: -100

400mhz: -200

800mhz: -200

1120mhz: -200

1300mhz: -175

1400mhz: -125

My highest benchmarks tested at 1.4ghz are as follows:

Quadrant Standard: 2228

Smartbench 2011: 1223/2818

Smartbench 2010: 1600/3437

I find these results amazing considering I was unable to even run 1.4ghz on other kernels.

The bulk of stress testing was done using Smartbench 2011. I ran it once each time I decreased mV one step until I found the limit, then the final value was subjected to two runs along with one quadrant run back to back to ensure stability. Anything above stock speed was subjected to 3 smartbench 11' runs, 2 quadrant runs, and a smartbench 10' run.

I'm glad I did this because it seemed 1.4ghz ran fine at -150 on smartbench11 and quadrant, but crashed on smartbench 2010. I increased voltage one step at 1.4ghz and 1.3ghz as a result.

I want to thank the creator of this kernel along with the creator of voltage control, this setup is truly awesome.

[Epic 4G Android Development] konaman:
Man 1greek I saw ur post so I figured id give it a shot and as soon as I undervolted 200-600-800 and hit apply for now BAM she froze. I still need to tinker with my settings I guess
[Epic 4G Android Development] bryanberlin:
You really shouldnt be seing the heat you are talking about.

The phone does have a thermal shut down to protect it from frying the CPU.

When your running the phone through the paces you really dont spend but 15% or so at max clock. (check in cpu spy). make sure you didnt set idle at a high setting. for example a clock at 1200 may have an idle at 100 or 200 at the highest. Ive read posts where peeps were running 1200/1200 which isnt really testing anything but trying to fry the processor. 1200/100 or 1200/200 is mmore like it.
[Epic 4G Android Development] bryanberlin:
The ability to undervolt specific steppings and fine tuning your phone can lead to incredible battery savings. Oclocking is only one way to go if your intrested in "not pushing it " run stock voltages and see how fast you can go and undervolt the idleing stepppings for battery life. You should be able to flash this kernel and be good to go after cache and davlik wipes x3. = yes id say its worth it.
[Epic 4G Android Development] mrhocuspocus:
great job, this is simply amazing. thanked!
[Epic 4G Android Development] jspsuperman:
I double checked to make sure I have it all set properly and its good, but still crazy heat and ive only set it to 1.125 max and 200 min. Idk what else to do but go back to his previous kernal :( also I did not mess w any undervolt settings at all
[Epic 4G Android Development] XxLostSoulxX:
Does the battery heat up or no? plus my phone froze with those settings
[Epic 4G Android Development] jbadboy2007:
I bet he hasn't responded yet cuz his froze to and he got corrupted data and is still re flashing everything lol. What I've noticed is that you really have to test is the throttling aspect not the pegged at one frequency approach and benchmark. What I mean is actually use phone the open keyboard, rotate screen, use it as normal go through all operations and also make sure your screen will wake that's a result of uv 100mhz-200mhz too much. I still have not hit the save as boot settings and I've been running this for 2 days now.
[Epic 4G Android Development] theimpaler747:
Yeah, that takes some work for sure, took me about 2-3 days as well to get it down.
[Epic 4G Android Development] jbadboy2007:
what's your config??
[Epic 4G Android Development] roghaj:
Mine is running fine with one exception. It freezes on the shutdown screen. Pretty odd that I can run quadrant nonstop, but can't shutdown.

Anyway, for those who seem to get results that are unbelievable, I bet you are missing a step.

When you select the undervolt amount, hit the arrow to make the slider go away. Next hit apply for now. If you only hit apply for now, it doesn't seem to update to where the slider is at.

Good luck undervolting.

My new setup:

200 -125

600 -75

1000 -50

I may be stable with more than that, but that should be realistic for most.

I still say that enabling more frequencies will reduce your battery life.

Edit: I also think it isn't too smart to try to do this with journaling off. Find what is stable first, then switch to a rom without it. It won't cause any damage, but every few crashes you will need to reload the rom.
[Epic 4G Android Development] 1greek4u:
I guess this is just it. I tested each frequency individually and I was able to get pretty amazing undervolts. Realistically with all the steps enabled the phone isn't even near to stable. I guess I'm just going to continue doing benmarking with ALL the states enabled and a much more conservative undervolt.

Wish me luck,

1greek
[Epic 4G Android Development] 1greek4u:
It all comes down to voltage. If one's concern is battery life they are better off having multiple low-mhz steps enabled (200,400,600,800) etc because the phone will use less juice with lower voltage.

For example, if your epic requires more processing power than 600mhz, and the next available step is 1000, it has to go to 1000 (along with the higher voltage) as opposed to hypothetically going to 800 where the voltage would be less than the latter.
[Epic 4G Android Development] roghaj:
Read the post before yours! If it seems amazing, it actually isn't enabled. The single state stress test worked great for me. I just backed off 25mv from each stable state (lower battery or high heat will be less stable) and am having a good battery day today with no freezes or problems.
[Epic 4G Android Development] roghaj:
I understand that concept, but in reality the steps take time. A job that requires 1000 will waste more time getting to 1000 if it needs to step on 400, then check if processor is above 80%, then step to 600, then check if processor is above 80%, then step to 800 and so on. So the phone will take longer to finish processing and therefore take more time away from the lower voltage states.
[Epic 4G Android Development] Custodian:
Pretty much the same settings as mine, except im running stable for two days now at:

200 - 150

600 - 125

800 - 75

1000 -75

Let's get it! ( I baught my phone about a month ago, if that matters )
