I run both mate. They operate differently and each have a task to serve. On the settings, well the ones that the developer has put as default seem fairly stable. Just grab the UV apk from the market and open it up. Give root and set speed to desired settings. I run full 1400 hit apply and go to volts tab. Of the dots are red hit em and turn e. Green. Should already have setting there but if not I started at 25 under across the board and uped it as j felt it was able to handle it, eventually you will hit a point when it makes your freeze or reboot. At this point you have gone too far. Take a step back and logicly that's gonna be the best settings for your tab. Well today anyway, be prepared to adapt as your usage and the os change.

i just uploaded 3_0_8b

change log:

changed LCD voltage 2.6v to 2.4v

remove automated_per_tty_task_groups

optimized compile options for arch_cortex-a8 sine 3_0_8

ATTENTION!!

NEED A LOT OF TEST

[/COLOR]

heimdall:zImage_euro_3_0_8bNEW!!

cwm:zImage_eur_3_0_8b_cwm.zipNEW!!

@bartito

i feel noise on LCD when 2.4v

but,many people don't feel i back 2.4v.

if you get noise on LCD ,please teach me it.

kotirakoso arigatou.

me too. when i make tab run hard work on the CPU. tab spend alot of battery.

but,in sleep, it's normal usage.

maybe automated_per_tty_task_groups is using alot of cpu power.

i turn off this function.

also i may understand why wipe cache.

i completely forget that i apply a patch for optimizing compile option.

it need to wipe the cache.

@PROTOCHIP

i just tested camera with 3.0.8 .it work fine. please wipe any cache in cwm.
[Galaxy Tab  Android Development] PROTOCHIP:
Dear koxudaxi ,

Camera has weird problems with 3.0.8 ; sometimes it works sometimes not, especially the videocamera section has bugs now but just taking photos seems to be normal.i. There was no problem like this in 3.0.7 Hope this helps.

Kind Regards,

I got a galaxys (togheter with the tab!) and I flashed the 2.3.4 that is out now...2.3.4 has great battery life when compared to 2.3.3 ... I hope samsung

will do the same for the tab ...cause 2.3.4 is great and got also the animation activated!

my galaxys with 2.3.4 is able to stay a full week in standby when with 2.3.3 after 3 days it was almost dead!
[Galaxy Tab  Android Development] The Transporter:
Works good on my gt-P1000 from belgium, now the screen brightness slider in the notification bar works too!

YESSSS...finallly 3.0.8b has good standby battery life!

I wonder how you guys gets 3000+ in quadrant.... obviously there is something wrong in the test...

cause a stock ginger rom + ext4 + 1400mhz gets 2100 REAL points sometimes a lil more sometimes less but 3000+ sure is fake!
[Galaxy Tab  Android Development] AndroidGX:
Actually testing 3.0.8b, just flashed it from 30 mins now, but it seems everything working fine. Camera shot/recording no problem, same for brightness, no FC, no reboot for me.

Flawless work, as usuall, many thanks koxudaxi!
[Galaxy Tab  Android Development] DarkPal:
+1 just downloaded it and testing it for you kox. Will report later with the results.

EDIT: Can confirm extensive battery drainage. Lol the battery meter is going down like crazy. No OC/UV was done plain default. Standby is ok but using kills battery very quickly comparrd to before.
[Galaxy Tab  Android Development] af974:
same here, crazy battery drain.

I also noticed that screen doesn't "tilt" while you are installing like with 3.07, dunno if it is a problem though lol

Nice work btw :)

v.308b

On v 308b Not support Voodoo Sound Version 9*?
[Galaxy Tab  Android Development] Alvin Lai:
I really don't understand, what so great with all those benchmark test. What I really care is stability and usability.
[Galaxy Tab  Android Development] koxudaxi:
thanks everyone for repots

Is camera and screen ok?

that is big problem ....

3_0_8 cut battery life.

also 3_0_8b is same ?

i must solve this problem....

3_0_8b support voodoo sound version 9.

my tab just worked voodoo sound on 3_0_8b
[Galaxy Tab  Android Development] DarkPal:
Koxu Senpai. I recharged the battery and will try for one other full cycle. So far so good and stable. Voodoo is working here too.

Good work koxudaxi. You have the talent.

EDIT camera is working but takes a little more to load. Will report back about battery after this cycle is over.
[Galaxy Tab  Android Development] koxudaxi:
thank you

ok,i'm waiting your report about battery.

btw, why do many people know japanese?

in around world, can you listen "sensei" as word?

also "senpai" is common japanese ....:confused:
[Galaxy Tab  Android Development] Yom:
That is because Japanese is a beautiful, elegant, precise and expressive language, koxudaxi-san! Ohaiyo gosaimazu :)

Arigato!

Posted using my hacked, rooted, undervolted, overclocked, pimped-out and overall bad-ass Samsung Galaxy Tab.
[Galaxy Tab  Android Development] Alvin Lai:
Voodoo sound not working for me. Revert back to 3_0_7.
[Galaxy Tab  Android Development] DarkPal:
Loool. Well koxudaxi. My other half and I are anime and J Drama plus gaming fans my friend hence knowing alot of Japanese. Plus one of my close friends is learning japanese too. Btw many of us donated and support japan to recover from the evil tsunami :)
[Galaxy Tab  Android Development] AndroidGX:
Hard tested the 3.0.8b for few hours now, and flashed back to 3.0.7 to see the difference of battery drain it could be, sincerely, I see no difference, it drains the same for me here.

Lost 6% in 15 mins on 3.0.8b. It that normal? anyway since I have my GT, I guess this is normal drain, isn't it ?

I can confirm Camera loading is a bit longer on 3.0.8 (b or not) than 3.0.7 too.

Otherwise, no problem detected so far. Screen backlight is perfect, Voodoo sounds are there, and everything else are too!

Great job kox!

i love japanese, but a lot of language have different with japanese.

i think many people can't understand :(

it may be false thought ...

ok,i will check source code .

i just understood it.

thank you,support and donate .we are deeply grateful to you and a lot of people.

i have removed signature about to the earth quake.

That incident is noew three months past....

i must look the future to make it the best.

thanks good report.

1.camera loading time is longer 3.0.7

2.about battery drain is same ...

i will research it.
[Galaxy Tab  Android Development] DarkPal:
So far battery drain is better 15% in 1hr and 50 minutes. Will continue testing. Just check the long loading camera issue.
[Galaxy Tab  Android Development] nobleskill:
Hey darkpal, What about Voodoo for you? Do you do voodoo that u do well??

lol

@Kox bro!

Hey mate. Wanted to report that 8b seems alot better for me too on everything except voodoo. running V2.blah-something.beta i think and original headphones. About to go dig another pair up just to confirm they are not the issue so will report back. :-)
[Galaxy Tab  Android Development] DarkPal:
Voodoo is working for me. So far so good. I use it to crank up the headphones volume. And it seems to be working. Any tests you want me to do?.
[Galaxy Tab  Android Development] nobleskill:
Nah bro all good. Ill keep testing my end just to be sure its not me. Thank you for the offer though. One thing actually is it correct to assume your on overcome? Im using Dip7s GB ROM so maybe thats a factor too?
[Galaxy Tab  Android Development] DarkPal:
Yes am on overcome GOLD. I have issues with Dip7 ROM.overcome GOLD works well for me.
[Galaxy Tab  Android Development] nobleskill:
Roger that mate. Its 2am and im just back from pub anyway so gonna go crash out and start again with a fresher mind.

Peace Brother.

:-D
[Galaxy Tab  Android Development] :
battery compsumition on ginger is very bad!!!
[Galaxy Tab  Android Development] DarkPal:
I think the voodoo problems are arising from the root issues on Dip7 rom maybe. A broken busybox version maybe? To all those having voodoo try fixing those issues and see if voodoo works out for you.
[Galaxy Tab  Android Development] koxudaxi:
i just build to solved camera loading time and voodoo sound problems.

i deleted linux kernel version up patch from 3_0_8

this patch have changed a lot of drivers include sound and media

it may have an effect on many driver.

please check it.

and i will sleep soon.it's 1:36am

i'm going to work on sunday

ATTENTION!!

NEED A LOT OF TEST

heimdall:zImage_euro_3_0_8cNEW!!

[Galaxy Tab  Android Development] DarkPal:
Thnx koxu. Downloaded and will flash to test. Battery life is a little better now. 25% drop in 2hrs 47 minutes.

For those of you interested in a decent, smooth configurations. I will share my settings (I am not being a fanboy or a fanatic). I just am sharing my settings after extensive testing).

ROM: Overcome Gold based on Gingerbread 2.3.3 JQ1 build

kernel: koxudaxi 3.0.8c now :D

Governer: on demand

UV/OC: Only uv -75 mV across the board (stable). I suggest you start in -25 mV increments till you hit the sweet spot.

Utility: Voltage Control (setCPU causes system instabilty with my tab).
[Galaxy Tab  Android Development] nobleskill:
I gotta say mate, I've not had one problem with Dip7 GB rom before now. I didn't even know there was a known root issue cause everything else seems fine. You know me too I'm not shy with much, so my tab is busy alot with me rooting it... budum bum, chhhh ...

Lol I've found it to the strongest and fastest ROM for my tab at any rate. Like OC though the kernel is not so fresh , hence being here. I'm in Australia though while is often lumped in the Asian markets. Not sure how that would make a difference but I know you and know your no goose either so trying to make sense of it.

I've just grabbed that new update, can't sleep so pipes it is and ill test the new zip as I go.

Niiccee

Just real quick tho,

I'm inclined to say that at this level of tweaking the very nervous system of the tab, there really isn't a one size fits all. Again I know your no goose, neither am I, however I'm the other way about setcpu. If its not running for whatever reason I get bugs popping up.

I guess what I want people to do is think for themselves on that stuff. If you are not prepared to help yourself here then you should stick to the step by step guides provided by the main releasers. Otherwise people are just going to come in and say "I used your settings exactly but a purple dog weed on my foot... fix it, its ur fault" lol

[Galaxy Tab  Android Development] DarkPal:
+1 in so many things. True no one size fits all. And as one of my greatest friends and mentor told me as I came here a noob in the dark just feeling my way and taking baby steps. Find the configurations that work out for you and stick with no matter what others say or do. Its you who will be using the tab not them.
[Galaxy Tab  Android Development] triplex76:
yes...you are right ...and to make the thing even worse there is the ext4 consumption!

I wish samsung release 2.3.4 gingerbread that got most of the bugs solved and INCREDIBLE battery life on overall every devices tested.

my galaxys kept new life with 2.3.4 smooth and 3 days more of battery life with the same darky kernel...so just the rom makes a big difference...the battery issue is inside 2.3.3 rom ... every devices with this ginger lost half of its battery life compared to froyo!:(

I hope samfirmware will give us a leaked gift ASAP:D
[Galaxy Tab  Android Development] nobleskill:
Lol we will have to be careful not to start a love in but those are elegant and apt words. So true about so much in life too. Deep man.. B-)

After saying that though I wanna share what I just worked out I've been running for 3 or 4 days now I think. Was waiting for a freeze that never came and just forgot. Smartass and;

I'm confident enough now to start high and work back but these are the best I've had running on GB.

Also Voodoo is back. Not sure what it was. Headphones are fine. Ended up doing an uninstall/re-install of voodoo apk and data wipes in a couple places and so on. Something I did fixed it. Or it was a gremlin... hmm

Glad you are up and running getting your issues ironed out. I was shocked to see that galaxy i9000 got2.3.4 before us (thought we were proud owners of a pretty expensive device). Sammy makes no sense.
[Galaxy Tab  Android Development] AndroidGX:
Do I am the only one here that actually see in system infos that the kernel on 3.0.8c is back to 2.6.35.7 instead of .13 ? :confused: is that normal ?

Anyway, everything seems ok, as usual ;)
[Galaxy Tab  Android Development] DarkPal:
Yes that patched was removed. It was causing a battery drain.
[Galaxy Tab  Android Development] AndroidGX:
Ah ok!

Thanks ;)
[Galaxy Tab  Android Development] Alcibiade:
Like many I am on overcome Gold + koxudaxi's kernel

Seems I dan't undervolt at the high end of the spectrom. While i was on Froyo (Overcome 1.6.x) I could undervolt to -200mV all across the board, I just cant anymore

I read in this thread others seem to experiment the same issue. Did you find any solution ? Or is it just that in Froyo it was not having a real effect on the voltage provided to the CPU (which I suspect is the answer...)
[Galaxy Tab  Android Development] nobleskill:
It doesn't seem right huh. I guess though it (I9000) would be arguably the most popular Android handset of its Gen.I don't get what went wrong with the Tab sales though but it seems to not be around, well here in Australia anyway. Apple would and did have play a part in this with the negative press about returns and the other little things that popped up funnily enough at launch and then got debunked later but the damage was done. I think the Galaxy Tab II 7" whatever it ends up as is going to be the business but even here at xda this current one just doesn't have the interest or support of the developers.

I lobe this thing. Its so much more than I ever thought it would be. Its actually really enriched my life in some very cool ways. Quick example, then 430am so sleep. I used to read alot of books as a school kid. I had 2 or 3 going at a time sometimes. Anyway long story short I stopped when i stopped carrying a bag around with me. I started reading again on the tab recently. They are there and i can do it easy so i do.

Well yup battery seems all good. Voodoo is all clear. UV settings seem stable. Video playback as smooth as silk. Snappy on everything. Just fantastic work again on the kernel.

<3 the releases mate. Just awesome in the true sense of the word. Thank you.

Play nice kids for my sake pwetty pwease. Koxudaxi battery life is a bit better am coming to around 6h 25 minutes now at 9% I dont use the BLN app any my keys sometimes blink randomly when the tab sleeps any reason for that.

Latest mate and yeah almost no loss at all over in 4 hours screen off no charge.

@DarkPal aww they started it!! Lol. I am a red head though... temper temper

EDIT: never mind. http://en.wikipedia.org/wiki/Alcibiades for those interested.

EDIT2: practice what u preach. So i re read your posts and... Overcome huh? I dunno about the current overcome rom with UV .. seems to be more sensitive to it on SOME hardware. Ie my tab here in Australia prolly from Asian stock? Or maybe Europe? Anyway it didnt like the new overcome, especially when UV was added in the kernel mix but is thriving on dip7s Asian based rom with the silly UV setup I posted above. Reference the post by DarkPal though and you will see on the other hand has better results from Overcome. And that's where what DarkPal and i said earlier... there are just too many variables at this level of tweaking to troubleshoot if over forums. My advice though would be do a clean install of whatever rom he keen on ATM. Restock, no data in titanium restore and as few apps to start as possible. Fingers crossed as you add stuff back in you will be able to catch the culprit out.

Wait what? So which is it? Is it running all good or are you having baterry issues? Anyways....

For users on jmi you can also overwrite the sensor using root explorer. Make sure you check r/w option when overwriting the file.
[Galaxy Tab  Android Development] bendjlee:
I need some assistance with setting the clock voltages on boot.I have made the assumption that titanium backup downloads the latest busy box hence I am not sure about your guidelines to install busybody to systems\bin\busybox...now all I have been able to do after running the APk is to set the voltage on my current session.if I reboot my tablet then these settings.are gone and I am back to the stock voltages,can anyone point me in the right direction?
[Galaxy Tab  Android Development] darrenjdoc:
Excellent work.

Where do you add - ocpatch.txt ?
[Galaxy Tab  Android Development] bendjlee:
Looks like I am finding the answers to my questions.tonight via trial.and error:-D

So as I mentioned above I was trying to figure out how.to undervolt my.clock rate on reboot.

So far I have the following setup

Euro tab

Modaco rom

Kernel update

Sensor patch (pushed using root explorer)

Voltage apk from main page...

Next I upgraded to the latest busy box using titanium backup

then whilst in root explorer I did a search for busybox

Upon locating the busy box I downloaded for titanium backup I copied the folder

Navigated to system\bin and pasted the whole busybox folder

Returned to the voltageapk and undervolted my clocks

Saved the settings - reboot

All done

Oh am running 1400 at 1300ma but my tab seems to get quite warm, like 37 degrees

You could have just downloaded it from the market and installed it to system\bin :)

[Galaxy Tab  Android Development] koxudaxi:
thank you for a lot of posts.

i may not answer to all posts

because i start to develop a OCkernel.

1.6GHz: very unstable.

cwm: i'll study about it to set on my kernel .

camera : i'll add patches to work a camera soon.

other region's tabs : it will come soon.

Where do i add ocpatch.txt ?:add 1.2 clocks table,change voltage,change a few numbers to increase a clock position(1.4GHz).
[Galaxy Tab  Android Development] daniel.weck:
Thanks ! :)

I'm running JMI (with minor optimizations from the stock Samfirmware version...only removed a few APKs and background services). Oh, I run at 200 screen density.

I'm using SetCPU to trigger a "performance" profile (when charging: 1Ghz - 1.4Ghz) and a "power save" profile (when screen is turned off or when temperature exceeds a set limit: 0.1GHz - 1GHz (0.8GHz when temperature is high)).

I haven't changed anything in voltage control.

The score is 1250 on Quandrant, baring in mind that I am still using RFS (not Ext4) so this result is pretty meaningless anyway. Linpack says 19 MFLOPS.

In practice, it is a snappy and stable device :D

EDIT: camera fails here too (sensors OK, wifi good so far, haven't tried GSM calling yet).

[Galaxy Tab  Android Development] triplex76:
thanks for your work ...

right now it works well on JK5 firmware...

it would be awesome if you can remove the ntt logo and implement the CWR...

strange enough this kernel works without any locks at 1400 mhz even at -200mV at all settings...when the richardtrip one locked sometimes even at only 1200mhz!

I think that my GT could manage 1600mhz without problem ...it depends from the sample CPU...maybe you could add 1600mhz ... if not working for the most they can always set to 1400mhz using setcpu...;)

[Galaxy Tab  Android Development] Landroid:
when is someday?? ;)
[Galaxy Tab  Android Development] daniel.weck:
May I suggest that fixing the camera should get a higher priority in your task list, so that the Euro zImage is fully working before developing other platforms ? :)

By the way, what is the easiest way to convert to EXT4 when using this kernel ? Shall I install another CWM kernel first, so that the partitions get converted from recovery ? Many thanks, Dan
