Undervolting?

I don't mean to pressure the devs in any way but is there any possible way of successfully undervolting this sucker? I'm getting killer speeds overall. Its almost too fast! :D

But my battery is crying. It actually goes slightly downwards charge when plugged in through usb while in heavy use. Some undervolting would help!

I couldn't seem to find any kernals (expiromental or w/e) for cm9 that allows overclock/underclocking. Whats the latest news?
[AT&T Samsung Galaxy S II SGH-I777] tmckenn2:
Entropy is looking into things related to this. things related to this include: schedulers, Governor, over clocking, and undervolting. all of which is kernel related. so it is being worked on but he is running into stability issues.

for those of you with knowledge of code and code review... or who can wade through info and figure i out yourself go to review.cyanogenmod.com it is the gerrit code review side and where commits are done for this rom. there are some really great submissions on there that are yet to be approved. im praying that they do because some of the settings on there are what ive been waiting for since the beginning of the world.
[AT&T Samsung Galaxy S II SGH-I777] msprag13:
Check the new settings section for profiles as those will take precedent over the other changes. Check what you have set for the default profile.
[AT&T Samsung Galaxy S II SGH-I777] brendonlee:
It has had them for a few days now. I think it may have been an accidental merge of the changes or something. Atinm has previously said you can refer to the galaxys2 change log as it is our 'base', but the API is currently down as beerbaronstatic mentioned.

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Yup. Due to the SoD/etc issues encountered earlier this week, everyone is a bit more careful about pushing new kernels through gerrit. I've got voltage control there but atinm is beating on it for a while to make sure it's stable before approving it. I may need to remove some stuff (gokhan's sio iosched code might be wonky, one negative stability report) for it to get approved.

I seem to have finally gotten stability issues licked last week - my device has been nice and stable for days. However the Easter holiday slowed everyone down - and at least in my case, I'm going to take it easy next week because the past three weeks have fried me. I might do mali 3-step GPU later in the week then OC the next week.
[AT&T Samsung Galaxy S II SGH-I777] tmckenn2:
3-step gpu would be spectacular. are your latest changes on the github. i might build a kernel and test it if i have a day where my phone isn't critical.

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Kernel changes are on teahmhacksung github and have been since early-mid last week, and an (older) VC kernel has been on gerrit review for a few days now. I may refresh it tomorrow with a newer build that rips out sio for the time being.

Is phone unlocked? On my win 7 box if the phone us at the lick screen and I plug it in I font get any drives. If it is unlocked when I connect it does which I think is good.

For Mac just use the free osx transfer app from android.com/transfer

Works like a charm.

modems

Hi guys I have been running cm nightly 04-5 for three days now and i gotta say its been rock solid so far thanks to the cm team for that. What I would like to know is is there really a significant difference in flashing the modem? for now Im running the ckk6 that came stock with the rom but I see people running different modems. and got me a little curious.

thanks in advance
[AT&T Samsung Galaxy S II SGH-I777] projekt1:
The different modems for the most part depend on where you live since it affects your network connection. The UCLC5 Modem works well for me. Check this link out: http://xdaforums.com/showthread.php?t=1361393
[AT&T Samsung Galaxy S II SGH-I777] TOA Duck:
Depends on your area. Go look at rockratts thread in development for tips on finding the best modem for your area. Be sure you flash a cm7 modem, not stock.

thanks projekt and TOA, lots of reading to do...btw duck just for clarification I need to flash to a cm 7 modem first?? I cant just flash from the cck6 that cm9 put on when I flashed to the rom?? I came from the h7 when i did entropy512 return to stock 1 click odin package. I just want to make sure so i dont screw something up.

again thanks in advance
[AT&T Samsung Galaxy S II SGH-I777] KevinChaos:
You'll be fine. Basically there are 2 modem packages for our phone. CM7 modems (which also work on cm9) and samsung modems. They flash differently, so you'll need the proper type for what you're running.
[AT&T Samsung Galaxy S II SGH-I777] aj9507:
thats what i thought thanks
[AT&T Samsung Galaxy S II SGH-I777] aspen1135:
Underclocking statistics!

So i was really bored and..well I went into the performance settings in cm9 settings and got lost like a little kid on facebook..Turns out, the underclocking works! But to what extent? It all depends on your other cm9 visual and CPU settings mainly and not the clocks.

Right now I'm rockin the latest build 4/5 with CPU gov on 'conservative', 200mhz min to 1000mhz max W/ the surface dithering and 16 bit transparency enabled. Overall it seems BARLEY less snappy and overall stable while enhancing battery significantly.

I found that the surface dithering makes a huge quality difference in color and line 'crispyness', especially in live backrounds..but takes a good amount of additional processing power. 16 bit transparency seems to lighten the CPU rendering slightly, while taking away some very slight hints of text shade and fade transparancy. I thought it was worth having on to balance it out a bit.

Under settings>developer options, i have 'Force GPU rendering' enabled as well, which not only boosted my 2d quadrant scores, but also the overal score. I'm unsure about its power consumption though.

A setting of 'Ondemand' or 'Performance' with 200mhz min and 800mhz also seems stable and will save battery life but while under this setting i discovered the phone charges slower than the previously mentioned setting.

'Ondemand' and 'Performance' seem smoothest but will eat up your battery fastest.

Userspace seems to utilize the CPU on whatever window is in focus, and less in backround applications like wallpapers, sounds and other apps. This setting works, but you have to raise the minimum CPU mhz so it doesn't slow down to the point where it locks. Adjust the max to what u'd like (over 800mhz at least).

Powersave is still very buggy. I assume its trying to run all the code and such without using as much cpu power as possible. i tried minimum of 500mhz and max of 1200mhz and it was struggling to keep up with winamp and a live wallpaper, then crashed.

Remember people, i cannot guarantee any of this stuff is legit. I'd just thought i'd share my experiance and best settings.

Also: maybe i'm stupid, but i can't find the settings for the screen on and off animations. Help?
[AT&T Samsung Galaxy S II SGH-I777] atinm:
Sometimes certain devices add things to common code that is shared across all the devices and so yes, you'll sometimes see changes that don't actually apply to the i777 but because the code is shared, it is included in the i777 binaries as well.
[AT&T Samsung Galaxy S II SGH-I777] tmckenn2:
aspen the performance Governor locks the cpu freq. to the max setting so 1000 for you. powersave locks it to the min freq. 500 for you. there are some really good threads for describing the cpu Governors AND also the schedulers and such. i think it would be good for you to look at them considering the time you've spent researching this. Thanks for taking the time to look at this, i know its a time consuming process having done it in the past. I choose ondemand most of the time.

Do carriers throttle dataspeed?

I am on CM9 nightly 04/03.

For the first two weeks I used the standard modem UCKH7. Doing some speedtest I got my usual results, which are typically 3-3.5 Mbps and 1-1.5 Mbps

This weekend I flashed UCLC2 and it made matters worse as far as data throughput as well as consistency.

Quickly flashed UCKJ4 and ran a speed test. To my great surprise my first speedtest briefly got over 5 Mbps. I have never seen that down speed again.

This all jolted my memory and I remembered that the first few speedtests when I got my Galaxy SII (stock ROM) were are close to 5 Mbps. Never seen those speed again.

I am starting to wonder if the carrier (AT&T in my case) keeps a record of phone, modem and IP address and adjusts the data speed to say 3-3.5 Mbps, to provide a consistent throughput.

When the modem changes the network then treats it as an unknown device and gives full data throughput.

I wonder if anyone else has noticed this and if so, is this something to be exploited so we can trick the network into giving for dataspeed all the time?
[AT&T Samsung Galaxy S II SGH-I777] brendonlee:
Modem drivers perform differently depending on where you are located. For me, in Charlotte NC, KJ4 has always been the best offering 3-5 down. The others gave around 1-2 down. However the most recent (from the most recent at&t leak), LC5, is better for me than the KJ4, typically averaging around 5-6 down.

[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
There's no difference between "CM7 modems" and "samsung modems" - they're the same damn binary. There's just something broken in the updater-script for the CM7 packages such that they fail on Samsung firmwares.

I'm still on the UCKH7 modem. I've played with UCKK6 once or twice and it always provides poor battery performance at my desk. Haven't tried the leaks, I avoid leak components unless they provide something critical I just can't get otherwise. Other people have better luck with the UCKK6 modem.

[AT&T Samsung Galaxy S II SGH-I777] breeves002:
I know the audio problem is well known and honestly isnt a big issue for me... take your time in fixing it. I did find another glitch that is small, and very unimportant. If I use apple iPhone headphones with the remote to pause/play the music, after I pause, then hit play, the music is much louder. Is this happening for anyone else? Again, nothing that needs to be fixed now... just add it to the long list of fixes.

Another problem I've come across. It may just be me, and I may be jumping the gun on saying this is a problem. Twice today I have had to reboot my phone because data stops working. It will work fine, then suddenly go out and only way to fix is reboot. I've changed nothing. Same modem uckk1 I think. And same rom and kernel 4/05 nightly along with the cm kernel from that nightly. Any ideas? Anyone else have this? I changed apn settings last week. Worked fine up until now.

Thanks to the Dev team for all their hard work! Entropy keep up the good work. Looking forward to Oc/UV!

Because that is a safe assumption. Posters for whom this assumption does not hold true are posters who are violating the rules of these forums, primarily rule #1 - SEARCH BEFORE POSTING.

If you are unable to find information in the first post of something's thread - you should NOT be flashing it.

Try the other modem drivers, see which works best for you.

If that doesn't resolve the issue, try wiping data. I don't think anyone else is having problems with intermittent data connectivity.

And where is "Cid"?!:D

Edit: One question, how can I disable shortcuts from being made on the screen? This is annoying because after all my apps automatically get restored they each add a shortcut and I have to go and delete each one.. Again, not a big deal just would like to know how.

Most suggest to lower each level by 50mV, and stability test (basically just use your phone as normal) and lower until you run into a lock up. I usually use the phone at least a day testing before I continue to lower

That sucks. Had back surgery 4 years ago. Good luck.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Start with light undervolt, slowly work your way down 25 mV at a time until things start getting unstable, and back away a bit.

NOTE: DO NOT use voltage settings from another person's device - every device is different, and in fact this will now be reflected in your default voltages! Samsung bins their chips by what voltages run stable on them, and the kernel actually selects default voltages based on a binning code within the chip. These are the ones you see as defaults. (Search for "ASV" in arch/arm/mach-exynos/ of the kernel for more info.)
