Ya, I was using v6 supercharger to test the phone and found out that apparently, option 5 gave me best score. Then, I look into the script, apparently what needs to be changed are those 2 lowmemorykiller parameters. So, i extracted boot.img and edit the value in init.rc using those values. :D

Credit: zeppelinrox for those values... i hope he is not mad that I didn't include his script into the ROM :D

My SD card is class 10 :D . Ya, so, may be it's not fair. So, the Antutu score without SD card = 4048 - 150 - 180 = 3718

Again, this is the best case. ^.^

Sorry, no Italian language pack. It was modded from Malaysian ROM...
[Samsung Galaxy W I8150] mr_new_guy:
first thank you for your work sir :D:D

i have some questions for you

i see that you remove some default apps

can i uninstall those you list from my device using titanium in stock rom??

if i previously backup my app in stock rom and then restore them after installin your rom, will those app back to my phone??

sorry for bad english:o
[Samsung Galaxy W I8150] cowithgun:
yup, it will be restored. it's ok if u want to keep them. :) i remove those because i dont use 'em
[Samsung Galaxy W I8150] mr_new_guy:
i actually want to remove them also :D

so i have to de select them when restoring my titanium back up ;)

will try your rom tomorrow :D

thanx

The slim version link in megaupload seems to be not working..
[Samsung Galaxy W I8150] mr_new_guy:
yeah as of now the slim version link is not working :(

another question,

i saw you apply some memory tweaks base on v6 supercharge

does it mean i dont need to apply the script after installing this rom?

thanx

So, you're saying i'm doing it right BUT now i just need to replace the current 'boot.img' with your ROM's 'boot.img'? And btw, the 'dhd.ko' is important or else i cannot detect wifi, is it? One thing egarding my confusion on the '.md5', is my step right that i open it using root explorer and ONLY change the codes of 'boot.img' and save it as stated on my post before? :confused::confused::confused::confused:

---------- Post added at 06:38 AM ---------- Previous post was at 06:34 AM ----------

About the 'dhd.ko' file, i need to replace my current 'dhd.ko' with your ROM's 'dhd.ko' file, is it? Hmmm. :confused::confused:
[Samsung Galaxy W I8150] SyzwnFrzRdz:
Questions:

1. Replacing 'boot.img' = Copy 'boot.img' from the extracted EU ROM and then paste into ClockWorkMod backup. Am i right?

2. Calculating md5sums = Open 'nandroid.md5' using Root Explorer and edit it using any text editor and save it. Am i right?

I did both Question 1 and 2 but i want to flash it in recovery mode, it says the md5 is mismatch. Help me. :(:(:(:(:(
[Samsung Galaxy W I8150] cowithgun:
1. No! Copy the boot.img from my ROM into your ClockWorkMod

2. Just use the md5 value I provided earlier.

Yes, if you dont replace the dhd.ko from my ROM, you will not have wifi.
[Samsung Galaxy W I8150] SyzwnFrzRdz:
1. You mean replace right? :eek:

2. I know that i have to use your md5 value BUT what i don't know is how to change it? :confused::confused::confused::confused:
[Samsung Galaxy W I8150] cowithgun:
Yes, copy and replace it. Edit the nandroid.md5 file with a text editor. I recommend you re-read my post here:

Somehow, your OC-able kernel don't work on my phone. Really. Even the boot @ 1.4GHz won't make my phone to boot properly.
[Samsung Galaxy W I8150] SyzwnFrzRdz:
I experienced the exact same thing. :(:(
[Samsung Galaxy W I8150] darkteb:
Cow, i think the kernel need further tweak since it's randomly cause slowdown and lag when openup apps.. I'm referring to oc (boot at 1.4) rom btw..
[Samsung Galaxy W I8150] Thiso:
Me too, freezing during boot at 1.4 GHz
[Samsung Galaxy W I8150] TuxBrothers:
@ Cow, the performance is indeed not optimal, the gain of overclocking is about 10 percent in benchmarks, when running on 1.8GHz.

I would suggest trying to modify an XXLA2 kernel to overclock ;-)
[Samsung Galaxy W I8150] cowithgun:
If you can provide logcat, I probably can diagnose it a bit better.
[Samsung Galaxy W I8150] cowithgun:
Did you managed to flash it with no md5 checksum error?

If so, try provide logcat or more info.
[Samsung Galaxy W I8150] cowithgun:
Randomly slowdown and lag look more like problem with the CPU Governor. Is it on OnDemand or Interactive Governor? In my experience, somehow, the OnDemand is a more stable...

Will look into it. Thanks for feedback.
[Samsung Galaxy W I8150] cowithgun:
Most benchmarks take into consideration of many other things such as GPU, disk access, etc. The OC only speed up the CPU, others, are relatively unchanged. I suspect that is why most benchmark only gain marginal performance.

If you can benchmark only the CPU score (for example, CPU Integer only in Antutu) you will see that the improvement is pretty linear. I suspect you can get really good picture if you use Linpack benchmark, before and after OC.

Just install linpack, here is the result:

1.4Ghz = 46.782 MFLOPS

1.8Ghz = 60.529 MFLOPS

That is about 30% increment, which is similar to about 30% increment from 1.4Ghz to 1.8Ghz.
[Samsung Galaxy W I8150] jananan:
i think you typoed the Ghz as Gb...

yeah, there are tons of other bottlenecks, not just the processor...
[Samsung Galaxy W I8150] TuxBrothers:
Hi Cow :)

With stock kernel i get over 52 MFlops, with OC to 59, so the gain is not much.

And im also experience a lot of lag with the OC kernel, dont get me wrong, i really wished it was bringing us more! ;)

Is there a possebility to OC the stock kernel ??

Cheers!
[Samsung Galaxy W I8150] jananan:
i disabled that video.accelerate.hw=1 and testing...

i also reduced vm heapsize to 24MB from your 64MB, have to test with web browsing with multiple tabs open, i am not a heavy gamer so that is the only resource intensive task that i do - web browsing :D

vm heapsize of 16MB is no go for zeam launcher, just keeps crashing over and over again. haven't tested the absolute minimum but everything seems comfortable on 24MB so far... ;)

also i am not caching zeam launcher permanently in memory anymore...

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

update : 24MB VM heapsize still causes random crashes, now at 30MB
[Samsung Galaxy W I8150] cowithgun:
You are right, I just tested the stock kernel, able to get 50++ MFlops. May be this has got to do with the compile option I used. My OC kernel was compiled with arco68 configuration, which among other things (I think) was optimized for size. With this OC kernel, the size is smaller, thus more available RAM for phone. So, in this configuration, your available RAM is actually 352MB.

If I use the configuration I extracted from Stock ROM, available RAM become 351MB only.

There could be other optimization done by stock kernel too.

At the moment, the only thing I could think of is to use newer toolchain to compile the kernel. I was using stock 4.4.3 toolchain from Android SDK.

About the random lag, I have not experience it since I use OnDemand. But I suspect it's due to CPU Governor. It happens in OnDemand as well?
[Samsung Galaxy W I8150] cowithgun:
Interesting. Hope to see more tweak from you.
[Samsung Galaxy W I8150] tesna:
This morning I'm feeling adventurous, I tried to use smartass governor despite the warning not to use it :P. I was thinking, hell what the worst could happen, maybe just crash and if rebooted back to normal.

After I setcpu governor to smartass, without ticking automatically set when device boot to make sure that when something goes wrong setcpu does not set it back to smartass (previously I've always use interactive governor without major problem), after a while my phone start to crash then I reboot it.

After rebooting I'm surprised everything is crashing. When I open the setCPU the governor is in ondemand mode. The only thing stops the crashing is clear everything and flash the rom again :P Oh well lesson learned, always listen to the expert (in this case cowithgun).

And also, I'm also experiencing slowdown (only sometimes) and usually a reboot fix the problem. Is it because I'm using interactive governor? and I did set the lowest frequency to 125Mhz from default 250Mhz. I did not experience any crash using this setting, only the rare slowdown problem.
[Samsung Galaxy W I8150] jananan:
125Mhz is unusable. :eek: when the governor goes down to 125Mhz and comes back you will experience lag. unless the frequency polling is really really fast then it would be unnoticable...

try sticking to 250mhz as the minimum, even one step higher as the minimum is fine actually. i am pretty sure when android sleeps it does not sleep at the min value that you set here.

set min to 368mhz and max to 1498mhz, it should be smooth... ;)

also if you want to experiment, try setting the minimum and maximum to 1.8Ghz for a while, without applying at boot... you will see the responsiveness increase hugely, and battery getting sucked as well, not to mention the heat...

just try it for 5 mins... :D
[Samsung Galaxy W I8150] TuxBrothers:
According to memory experts vmheap size should be around 40mb :)

---------- Post added at 08:22 AM ---------- Previous post was at 08:10 AM ----------

Hi Cow :)

I would like to suggest, take a stock kernel, set it in OC mode, then release it, and from there, step to step to tweak it more ;)

The lag was in all modes.. ..:(

I really hope you can do something with this information :)
[Samsung Galaxy W I8150] jananan:
heap size depends on what kind of apps you run... i always go for lightweight apps... the lighter the better...

[Samsung Galaxy W I8150] cowithgun:
I have done a few benchmarking with the following configurations (all using latest Sourcery CodeBench Lite 2011.09-69 toolchain):

1. arco68 kernel + oc + stock configuration

2. arco68 kernel + oc + arco68 configuration

3. stock kernel + oc + stock configuration

4. stock kernel + oc + arch68 configuration

The only differences I can see is that, using latest toolchain, apparently, I am getting a better score at 1.4ghz ~ 50MFlops. Upper limit of 1.8ghz is still just around 60MFlops.

Since there is not much difference and I am still away from home (Chinese New Year is 1 week holiday here! :D), I won't be uploading the new kernel.

As of now, I am using latest arco68 kernel + arco configuration compiled with gcc 4.6.1. So far so good!

If you worry about battery life, I recommend to set the max freq to 1.7Ghz. That is because, at that freq, it actually uses the same voltage as 1.4ghz in stock kernel. I have been testing the ROM in the last couple of days, my battery last longer (than stock ROM) when I set max at 1.4Ghz. That is because at 1.4ghz in OC ROM, it is undervolt a little. :D Unfortunately, I still connect my phone to my notebook via USB a lot, so a nice long graph of battery usage is not available yet.
[Samsung Galaxy W I8150] TuxBrothers:

I really would like to get my hands on the native stock oc kernel ;-)

I did tried to replace boot.img from OC rom (boot 1.4ghz) to my non-OC backup. Phone doesn't boot from recovery. I took out the battery, put it back in, then phone booted successfully.

However phone turned off on its own few minutes after, and can't be boot anymore.

I suspect there are a few incompatibility issues regarding the OC rom with my phone.

Now both method to install OC rom doesn't work on my phone.. Pity me.
[Samsung Galaxy W I8150] Ibn Saeed:

How is the Battery life on this ROM ?

My stock goes on for around 6 hours only and then it needs a full charge.
[Samsung Galaxy W I8150] cowithgun:
Here is the kernel; freshly downloaded from Samsung Open Source site, modified ONLY to enable OC, compiled with GCC 4.6.1!

This kernel can be used on the slim version.....? :)
[Samsung Galaxy W I8150] cowithgun:
Can be used in any ROM. Follow instructions here.

Basically, rename boot-stock-oc.img into boot.img, dhd-stock-oc.ko into dhd.ko. Put it into your duplicated nandroid backup. Edit nandroid.md5 with the md5 value: 795febb5ce12cd9d5fe9a7b0db0272bb

The dhd.ko for this kernel is here: http://www.mediafire.com/?wckum8u8rvrwvkd

Hi Cow, :)

Will test it this evening and will let you know how it performs!

BTW did you see this tool? http://xdaforums.com/showthread.php?t=1248486

Maybe usefull to create custom kernels installer on-the-fly? :D
[Samsung Galaxy W I8150] jananan:
no unvervolting right ? because the previous kernel sometimes reboots after its been idle for 5-6 hours.

the weird part is that it does not reboot when using, even OC'ed at min/max 1.8Ghz

maybe you undervolted some of the lower frequencies ?
[Samsung Galaxy W I8150] andynroid:
Rite a flash via recovery .zip
[Samsung Galaxy W I8150] jananan:
alternately, can extract the custom firmware zip and replace the boot.img and dhd.ko and rezip it and flash in CWM. should work too... but of course that is only if you don't want to keep your apps...
[Samsung Galaxy W I8150] TuxBrothers:
@ Cow: :)

Now we are getting somewhere ! :D

Antutu: 4306

Linpack: 61,006

Did use Antutu cpu master 245-1800, govenor ondemand with a treshold of 50 wich make it much more responsive! ;)

Is this the latest samsung kernel ?
[Samsung Galaxy W I8150] jananan:
threshold of 50% ? that is going to eat right through the battery...

also with a threshold of 50 you wont be able to detect any instability with the system esp with frequencies below 1.8ghz as it will just scale to the next frequency without putting stress on the current frequency.

having said that, the system will be super responsive with threshold of 50%

try setting min/max at 1.8Ghz and re-run the benchmark...
[Samsung Galaxy W I8150] TuxBrothers:
Well, for example yesterday, i played a lot with the phone, called a friend for about one hour, and still at the end of the day i had more then 25 percent left.

So if it eats 10-20 percent more, so i really dont care about battery power :D

Yes the phone is a F1 car at the moment, very, very responsive, i like it, i know the treshold is very low, but its scaling very quick down, for example if you looking at a page on facebook, and you hold it in place it directly scales down.

Normally i had to wait for about 5 seconds for facebook fully loaded, now it only takes 1-2 seconds! :)
[Samsung Galaxy W I8150] cowithgun:
Here is the difference between stock and OC in term of voltage:

Stock:

- 245mhz - vdd = 900

- 1.4ghz - vdd = 1275

OC:

- 245mhz - vdd = 900 (same)

- 1.4ghz - vdd = 1200 (undervolt)

- 1.7ghz - vdd = 1275 (same as 1.4ghz)

- 1.8ghz - vdd = 1300 (overvolt)

So, if phone remain unactive all the time, should have same battery as stock.

In Normal usage, if you set max as 1.4ghz, should have improved battery: at max 75/1275=6% gain

If you set max as 1.7ghz, should have same battery life as stock.

If you set max as 1.8ghz, should have less battery life, at max around (1300-1275)/1275 = 1.9% loss

Here is a graph when I set Max to 1.4ghz. Phone should last 2 days on my regular usage. In this case, there were 4 gaming sessions:

1. First slide - Plant vs Zombie for like 1 hour and 30 minutes

2. Second slide - media playing

3. Third slide - 3d game for like 20 minutes

4. 4th slide - browsing, media, Kies Air, install stuff, etc for like an hour

In between, some calls and all, this is as I can remember it! It's hard not to connect my phone to my notebook for 2 days!

So, the voltage differences are really minor, I guess the CPU Governor play more important role in battery life...
[Samsung Galaxy W I8150] cowithgun:
Nice. Apparently there is only 1 kernel released... I was able to get 61MFlops in some case when using latest Arco68 build too. Since the difference is not that much, and there are so many other bug fix in arco68 build, I am now using the arco68 build. :D

thanks for letting us know the the voltages that you used and the ori voltages, i don't even have a copy of the original samsung ROM so i wouldn't have a clue what were the original voltages... :D:D

i think the rebooting was caused by some other components, but anyway seems stable so far with this plain OC kernel...

i am testing the Sony Bravia Engine from Xperia series on the Galaxy W... it does some post processing when you look at photos... barely noticable sometimes but it certainly does something...

its like when you open up gallery, and touch a photo, it loads and for a split second you can see the contrast and saturation boosted on the spot. haven't noticed any difference on videos though...

and its not taking up more memory or processing power i guess... since its only implemented in gallery.

wifi not working after the reboot..

well, i flashed the one with 1.4ghz malaysian rom
[Samsung Galaxy W I8150] darkteb:
Cow, just wanna know if you're going to further update this rom? My recent issue is that my phone sometime turned off by itself even with half battery..
[Samsung Galaxy W I8150] cowithgun:
Sure can. :D First, download this kernel (it's compiled directly from Samsung Source with only the OC part modified. Using latest GCC 4.6.1!)

http://www.mediafire.com/?9pvbdct9ka32avf

Then, download the Wifi module:

http://www.mediafire.com/?wckum8u8rvrwvkd

Now, to flash this into your phone, try this:

1) Go to your CWM backup folder (ie: /sdcard/clockworkmod/backup/), create a copy of the backup folder (ie: 2012-01-xxxx). Put it back to the same folder. So you now have 2 backups.

2) Go to the new backup folder, delete the original boot.img. Copy the downloaded boot-stock-oc.img into that folder, and rename it to boot.img

3) Then, edit the nandroid.md5 to update the md5 sum of the new boot.img. In this case, the md5sum for this kernel is 795febb5ce12cd9d5fe9a7b0db0272bb

4) After that, use CWM, and chose Advance Restore. Pick the restore from correct backup folder (ie:2012-01-xxxx) and restore only the boot.img.

5) Reboot your phone. Finally, delete the dhd.ko from /system/etc/wifi/. Put the dhd-stock-oc.ko into that folder and rename it dhd.ko. Reboot again.

Voila! A new OC kernel with everything else remain the same. :D
[Samsung Galaxy W I8150] cowithgun:
Sorry, this ROM has no Russian locale...
[Samsung Galaxy W I8150] cowithgun:
About the wifi, it should not have any problem if you the ROM directly. How is the 1.4ghz working for you?
[Samsung Galaxy W I8150] cowithgun:
There was a wifi (that crash the phone) issue with the OC kernel which released earlier. This problem has been solved if you use the kernel from these 2 links:

http://www.multiupload.com/H8O62ZCBGY (ROM, need to extract the kernel out)

- or -

http://www.mediafire.com/?9pvbdct9ka32avf (Just the kernel) you also need the wifi module: http://www.mediafire.com/?wckum8u8rvrwvkd

I was researching on getting more available RAM to our phone. Stock ROM = 351MB, arco68 configuration = 352Mb. May be there is 1 more way to extract like 20Mb of available RAM for our device, but to do that, we need to scarify ability to record 720p video. Not entirely sure if it's worth the trouble. :D
[Samsung Galaxy W I8150] darkteb:
Cow, for my screensot here, am i using the latest kernel?
[Samsung Galaxy W I8150] cowithgun:
Did it boot up with 1.4ghz by default? If so, it should have fixed the wifi-sleep-reboot problem...
[Samsung Galaxy W I8150] andynroid:
CWG...........Best to housekeep your ROMS n integrate all the new kernels n fix's into the ROM without hassle.

Have tried tested all of your ROMS....The best stable one is is your Slim...the 1st released :)

Have tried with the OC and none OC version...seemed to be crashing as before blank screen n idle.

Guys...best to install the Slim version n to wipe / format and the Delvik............

Now using Slim version more than 24 hours......Stable !!! :)
