[SCRIPT] The Best RAM Optimization

Hello,
I just try this on my Asus Transformer and it seem to make a big different on the tablet smoothness.
Before when I either wake up the TF or running allot of program, it would lag allot. After the ram tweak, I can said it does make a different. Even after I had almost fill my memory up to 90%, opening new programs and swapping screen is fast. Android does a decent amount of work and return my memory back to 150 (and up) with the OOM Kill task. It did not cure my SOD problem.
I am current running the ram optimization with no other ram optimizer or task killer.
Here my TF configuration:
Prime 1.5, Netformer 1.5 @ 1.5GHZ, SD Boost, and Script Ram Optimization. The link is below. Check it out and let me know how it goes on your transformer. As always, make a nano backup before the tweak.

Hi, if you're running prime 1.5 it has support for sysctl changes built in. By using /system/etc/sysctl.conf_default as a guide, simply put the desired settings into the /system/etc/sysctl.conf file and these will be applied on reboot by the 04sysctl init.d script that's already in the rom.
Or just use the script for the post above, it should work fine too.

nice work !
By the way, what is SD Boost?

can i use this tweak with the netformer kernel and stock rom?

The default settings for I/O is really slow when it comes to SD r/w. With SD Boost app on market, it'll tweak the I/O parameters on boot. If you're running Prime, then it is already tweaked for you and is permanent.

But those files can be applied on stock rom with root and Kernel netformer 1.5 or i can fall in some issue if i don't have prime 1.5 installed into TF?

Apps like that or SD Speed Increase should be fine with just a rooted device at minimum.

and the RAM tweak? if i apply it with CWM on the stock rom (as i have done with wpa_supplicant to turn on Ad-Hoc connections) it's ok or i can have issues?

Here is what Roach2010 already has in the kernel by default:
[taken from the /system/etc/sysctl.conf_default file in PRIME v1.5]
NOTE: only the values that relate to what is in the script that the OP links to
Code:
vm.dirty_background_ratio = 5
vm.dirty_ratio = 20
vm.dirty_writeback_centisecs = 500
vm.dirty_expire_centisecs = 200
vm.swappiness = 60
vm.vfs_cache_pressure = 100
Here are the values to place into the /system/etc/sysctl.conf file that Roach2010 mentions above:
NOTE: these are the replaced values that relate to the script the OP links to
Code:
vm.dirty_background_ratio = 5
vm.dirty_ratio = 90
vm.dirty_writeback_centisecs = 1000
vm.dirty_expire_centisecs = 500
vm.swappiness = 50
vm.vfs_cache_pressure = 10
Looks to be similar to this app => https://market.android.com/details?id=com.rs.autokiller&feature=search_result

Cheers. I guess it falls in the same basket as autokiller etc. Highly debatable subjects.

Just from my experience. When I have using the TF for 4 hours, I would have use over 10 programs. opening the android market up would take at least ten seconds or more. With the ram tweak, it open up in two seconds.
Opening all other programs there after are just as quick, as if you first start up the Transformer. Switching from screen to screen is very smooth. Where with out the tweak it would lag for a few seconds if I have allot of programs running.
My experience with the tweak vastly improve the usability of the tablet. Then again, it is subjective.
Did not know Prime 1.5 already have the SD Boost tweak? Can anyone recommend me a SD Card benchmark tools that can work on the microsd, SD, and internal storage? Been looking on the market, but not that work for all the storage slots in one tools.
Thanks

I am using the Clemsyn version 16 kernel. Can I use the CWM RAM Script?
Thanks a lot

I don't see why not. OC does help with loading up the program faster and durning usage. The ram tweak help with the multitasking part. It use subjective though.
Do a backup before tweaking it.

A complete nandroid backup would a safer bet in this instance, or any other instance for that matter, in case you can't boot into your TF for whatever reason. It'll also be more convenient than having to find out which exact files are being modified and to use a root file manager to manually copy and paste the current versions before flashing.

It seemed to help me on my tf. Surprisingly I didn't have anything in my sysctl.conf before I added this in.

[Q] Does Overclock pay?

As the title says:
Does Overclock pay?
I especially mean, is it really remarkable on games (angry birds seasons eg), transitions, general performance?
Which method/apk u use(d)?
How much do you personal overclock?
Is it stable if phone´s use long times?
concerning this, what is a governour?
Thanks in advance for your answers

Well to be brief it pays
Though the entire experience is not that good if you try to run an HDPI game on our LDPI device, you can experience some lag of half screens
but other games like angry birds and all run flawlessly
The FPS of the games increase by appreciable numbers(Like sandstorm and other gameloft games ), though I havent yet faced any stability issue (Except the frequent Market FC) other things work normally
I use Lagfree governor and Deadline I/o scheduler
In short words governor determines how the frequency of the cpu changes with respect to the load on it

Thank you for the reply.
So I know it pays to overclock, now, as I won´t brick my second fit, is a question to me, how do I do this in a secure way?
Is is depending which ROM I use?
Is it APP or do I have to flash Kernel?
If it is Kernel which one matches with my ROM?
Many Questions, but before I make this step, I´ll be as sure as possible about this topic.

i've OCed my galaxy fit and so far i'm getting the best of my phone without any drawback. well if there IS a drawback, i think the only drawback it has is because of the governor which causes the phone unstable.
and to answer what a governor is, it's simply like a CPU manager which controls ur CPU speed at anytime. suppose i put my phone in my pocket and i don't use it, of course i don't want my phone to work 100%, no? so the governor slows down the CPU speed. of course, u can control what is the minimum speed of ur CPU (so far it's as low as 122 MHz for galaxy fit) and also what is the maximum speed (so far it's as high as 801 MHz)
there's so many governors but so far, the most battery conserving, yet doesn't sacrifice your phone performance when u need it most, is interactiveX. and the most performance efficient, yet doesn't suck a lot of battery juice when u don't use ur phone, is smartassV2. if u wanna know more about governors and I/O schedulers u can check it here
so far, the only OC-able ROM i know for galaxy fit is CM7, which is still unofficial but working properly without any significant bugs. and yes it needs to be flashed using CWM (it's CWM v5.0 for galfit so far). after u do that, u need to install some app like "no frills CPU" (market available) or "setCPU" (also market available) to make use the governors and set the max or min speed for your CPU.
to sum it up, how to OC ur galaxy fit (if u're using stock ROM or by now, CREED's ROM):
1. install CWM (ClockworkMod Recovery) link for tutorials and reference
2. flash CM7 (CyanogenMod 7 custom ROM) using CWM. link for tutorials and reference
3. flash ur kernels using CWM also. link for tutorials and reference
4. install CPU manager app like no frills or setCPU.
5. set ur max/min CPU speed, and choose the governor properly.
*update*
sorry for the wrong link. and by the way, did u bricked ur previous galaxy fit by using ROM manager? if u did, be careful coz this CM7 is pre-installed with ROM manager. i suggest u uninstall it immediately after u've flashed ur CM7. install Titanium Backup then go to the backup/restore tab, search the ROM manager, then uninstall it. ROM manager still isn't compatible with galfit tho
that's it and i don't mind u clicking the thanks button

Thank you also for the comprehensive answer.
I just have another question to that (gosh I hope I don´t get annoying to you all folks):
As I am using CWM and running ext4 and did the backup of my actual sys and would flash to cm7 like described in your answer, the cm7 is working fine etc, will I be able to "switch" back to Creeds ROM by chosing my backup, using cwm or do I have to flash it all anew?

i'm afraid i don't know the answer to that, sir.
well say that u've done the backup now when u're in CREED's ROM, u flash it to CM7 then u wanna revert it back to CREED's ROM, i think the safest way is to flash it all new the CREED's ROM, then do the restore data using CWM.
well, my guts say that if u're in CM7 n u do the restore data in CWM, u'll get back your ol' CREED's ROM, but it's just my guts sayin

I´ll try and report

I tried to start, but your links lead all to the same, the cwm Install Instructions.
still need cm7 link (cuz I am not sure which one of that) for cwm and the oc kernel (which I also dunno, which one of them. So if you pleasssse ...

thanks for correcting and also the notes.
Yeah I bricked it by using ROM Manager, but it was completely my fault.
I wanted to fast, without reading AND a special portion of being silly
If ya like read this:

edit: dunno what is meant by mount /system? What do I have to expect, when I am chosing this and what does it do?
As far as I understood is it being made between cm7 and oc-kernel installation. Right?

sorry for the long reply, it's sleep time in my country lol
mount system is a command to mount ur system folder in order to install the required. in this case, u're installing the kernel, so u need to mount the system in the recovery mode. to do that, go to recovery mode (since now u're using CM7 u can go to rec mode using the power button, choose reboot, choose recovery). then choose mount and storage, choose mount/system. don't worry, it's completely safe.
by the way, u also need to mount system for installing google apps in ur CM7 ROM. CM7 ROM is not preinstalled with google apps (including market, maps, and so on), so u need to install it manually using CWM also, flash the zip files provided in the tutorial thread. it's called gapps_bla bla bla if i remember correctly.
when i was flashing the google apps, i didn't get the market and maps application. so i install it manually using this link.
but i just read some guy with the same problem, n he said this.
haven't tried the later, maybe that'll work also.

Thanx again for all the effort. Sleep is an overestimated thing
But to be serious. I also slept and thought about that all and decided, first to stay with Creeds Rom, cuz it is fast, runs stable, looks good and has many features I apreciate.
Maybe I come back later to that point I wanna Install cm7oc, then I know where to look.

Still lets me no rest.
There´s still a new question in my head about the OC-Kernel.
there are many to chose, so which one is the most stable?

There are two 768 MHz and 801.2 MHz
Both are stable

There is also a general question about oc.
why can´t I just use an overclocktool like no-frills or cpumaster on any kernel?
They "promise" to increase speed, so why install OC Kernel first?
Although I know it must have a reason, cuz you oc-guys all do it.

kernel is the cars engine
no=frills is the accelerator
thats the way i understand it /

yes overclocking your device gives you that extra mile ..by which you can run apps faster ..your phones bagginess goes!!! but has its cons also!! ..it does reduce your life expectancy of cpu atleast theoretically .. and you will get reduced battery life + your device will heat up a bit more than usual! ..other than that its awesome to have an oc.

I finally can conclude, Overclocking really pays. And still I can decide to keep my OCed cell running with 600 at max or give it a little or maybe big OC.
Thank you all guys for helping me, sharing your knowledge.

I am searching for a program like no-frills, which can also decide by profile (maybe even autodetect) when my phones connected to charger ---> use this profile/governor, if it is running from battery ---> that profile.
Does a program like this exist?

Disclaimer:
I don't take any responsibility if your phone explodes, your girl/boyfriend breaks up with you or any other stuff.
Do not flash on anything else than an GT-S7500! No L model or W model, else you get a shiny brick.
Don't forget your warranty will get void if you flash this trough odin. (Unless someone figures out a way to reset the custom binary counter)
So flash AT YOUR OWN RISK.

Based on official Samsung Sources. Governors copied from freexperia github. Other changes by me.
Features:
- unsecured
- smartassV2
- SavagedZen (beware: in sleep mode cpu speed is capped at 480Mhz)
- noop sheduler by default
- minimium frequency set at 122Mhz
- enabled 19Mhz and 61Mhz frequencies (use setcpu or similar)
Click to expand...
Click to collapse
Tested with S7500XXLC2/S7500OXXLC1/S7500XXLC2. Flash with odin.
OC Build:
- Overclock frequencies seem to have the same performance but OC is indeed working, thanks to mb-14!
(Confirmed after many tests quadrant/setcpu/neocore cpu frequency is the same from minimal overclock to 1200Mhz)
- My phone as crashed 3 since I've overclocked it, so beware!
- Unless there is a better way of ocing, my newer builds will have oc disabled.
OC build v2 (31 May, 22h):
- Removed all overclock frequencies but 1200Mhz.
Bugs affecting all builds (even official ones):
- "Fuel gauge" might be bugged (maybe due to old/bugged samsung sources?) update:might be an rom bug instead.
- 3 pole headphones have noise in one channel and then the noise disappears (jack sensing bug?)
Sources Help & feedback are appreciated.
EDIT:
New kernel posted minimal changes again (samsung config updated from a new version LE1)
If you don't want an yellow triangle at boot flash my custom rom and then flash the kernel using the terminal.
1-Extract the tar.md5 file
2-Copy the boot.img to the sdcard
3-Use the terminal (or adb) as root to cd to the sdcard folder
4-Then type this "dd if=boot.img of=/dev/block/mmcblk0p8"
If you want to flash a custom recovery it works too, type "dd if=recovery.img of=/dev/block/mmcblk0p12"
Then you can flash whatever rom you want as long you don't use odin to flash an custom kernel or recovery you can keep your warranty intact (if you never flashed any custom kernel/recovery that is).
Keep in mind that this doesn't clear the counter only makes the triangle go away.

Custom recovery based on cm9 (5.5.0.4) posted (appears to work fine but more testing is required). Bootloop fixed. If you get stuck in recovery (unknown boot mode) go to "advanced" and choose "reboot recovery" when it is finished rebooting into cwm again choose "reboot system now".
DEVELOPMENT IS STOPPED. I no longer have the ace plus.

successfully flashed on my S7500DDLD1...only thing i noticed is after the flashing is complete phone doesnt boot normally but stays in download mode so i manually rebooted and i have ur kernel on my phone...take ur time and improvise it (startup scripts ,CM/MIUI support) , ALL THE BEST...

Wot's the benefit to flash custom kernel??.... Anyway gud step move ahead in making custom rom also for ace plus

Strange I can't seem to make it lag on savagedzen. The UI feels slower but music isn't lagging. Do you have any sound effect enabled?
Edit: I've got lag when using the EQ and waking the phone.
Edit 2: I've uploaded a hopefully fixed version, let's also hope that the changes that I made won't screw up the battery life.

flashed test kernel 3
the same bug exists wen used with EQ but the intensity of the bug is only 20% compared to the previous one also increasing the min freq to 480 completely nullifies the bug...also with EQ off the bug doesnt exist
will see how the battery life is... btw have u played with the drivers/bus to change the battery life...?

I can't get any lag at all now (after v3). Can you give my all your parameters? EQ settings, mp3 bitrate, where is your music stored and if using an sd card what type of sd card are you using.
I've set the minimum at 19Mhz and on air plane mode and by morning I still had the same battery than yesterday (89%).
The only thing that I changed was the cpu frequency table to include 800 Mhz at the same voltage than 600 Mhz and so far it seems ok, but might not be true to all phones.

I don't see any new kernel versions on the Samsung open source release center.. I'm still going to test oc did you change anything else than the CPU frequency table?
Edit: Overlclock is working! Thanks to mb-14!
Anyway it looks like the cpu when on OC is always working at the same frequency, since by overclocking it to 1017 I get an 150 ms reduction on setcpu native bench. And it remains the same for all the other frequencies.
For what I've understanded of PLL and CPU clocks looks like the cpu is running at 1200 MHz. (In the frequency table you can claim any frequency but it doesn't mean the cpu is running at that speed)
Edit: With OC my phone crashes after a while (ram dump mode)
Edit 2: Neocore doesn't seem to care too about the cpu frequency I set above the stock 1008Mhz. From 1017Mhz to 1200Mhz the score is always the same (85,6Fps)

[A510][KERNEL][2012-11-18] ThrillsKernel V2 & V3

ThrillsKernel for the Acer Iconia TAB A510
version 2012-11-18, built from source​
Here it is, the first ever non-stock kernel for the Acer Iconia TAB A510, dubbed the "ThrillsKernel"!
What's in this kernel:
Comes in two flavors: V2 for ICS ROMs and V3 for JB ROMs
Removed 'Samsung EMMC brick' bug: This prevents your internal memory from becoming corrupted.
CPU Governors: Interactive, conservative, ondemand, powersave, userspace, performance, SmartassV2 and lulzactive.
I/O schedulers: Noop, deadline, CFQ, Simple I/O, V/R and BFQ.
Removed Acer mount security: Now you can mount system as r/w.
NTFS, CIFS, and MD4 support
Tegra3 optimizations
Various other performance tweaks
Installation:
Step 0:
Check this thread to see if you can help the community before you let us help you!
Step 1:
If you don't have it already, install my CWM-Based Recovery.
Step 2:
Download the kernel from this post, extract the .RAR files and put the .ZIP file on your internal or external SD Card.
Step 3:
Start Recovery by powering down your device, holding the Volume down (**) button and turning it on again.
Step 4:
Make a Nandroid Backup. I can't stress this enough. Select backup and restore and choose one of the backup options.
Step 5:
Install this ROM by choosing install zip from sdcard and then choose zip from sdcard or choose zip from external sdcard.
Step 6:
Wait for the installation to finish (this takes a few minutes). Spend your time reading the text below these installation instructions!
Step 7:
Select wipe dalvik cache from the advanced menu, thenreboot system now, and enjoy!
Please read the following carefully before installing this kernel:
I am not responsible for anything you do to your tablet. Whatever you do, you do it at your own risk!
Which version should I install?
ThrillsKernel2 is built on the 2.6.39 linux kernel and intended for A510 tablets with a ICS ROM installed. That's Android version 4.0.0, 4.0.1, 4.0.2, 4.0.3 or 4.0.4.
ThrillsKernel3 is built on the 3.1.10 linux kernel and intended for A510 tablets with a JB ROM installed. That's Android version 4.1.0, 4.1.1 or 4.1.2. There is no support for 4.2+ yet.
FAQ:
Want to use ThrillsKernel in your own ROM? Go ahead, make my day.
Need ***** added to the kernel? Let me know, and I will try!
Want to remove the kernel from a NoThrills ROM? Although it's not recommended, it's possible. Check the instructions in the respective ROM thread.
Want to give me your first born baby? I'd rather not have that, but if you really want to give me something: Either click the 'Donate to me' button on the left, or simply hit the 'Thanks' button on this post.
Changelog:
The ThrillsKernel has the date as version number, e.g. version 20121118 is November 18th, 2012. You can check the status (or changelog, whatever you will) of the kernel by visiting the commit history of my github page:
Click here for updates to ThrillsKernel2
Click here for updates to ThrillsKernel3
Just check what the date of the ThrillsKernel is, and you can simply look at the dates of the commits to see if it's included in the kernel or not. Example: With the version from November 18th, any commit up untill that date is included in the kernel. With the 20120917 version, every commit up untill September 17th is included in the kernel.
​
Downloads:
The kernel is not released on its own yet, because I haven't been able to test it on many ROMs. If you want it, install any of my ROMs:
NoThrills A510 WorldWide optimized Stock ROM
NoThrills A510 "Franken700" Stock ROM
NoThrills A510 Unofficial CyanogenMod 10
ThrillsKernel is included with these ROMs as of 2012/09/17. Developers, feel free to extract the kernel and use it in your own ROMs.

Great new!

So it was Acer who was messing with remounting system RW?
Suggestion- maybe switching to TinyRCU is a good idea? It has a lower memory footprint and performs faster​

yep, great catch by nothrills, i should have seen this one

Is it possible to extend the minimum level brightness ?
When i read on night, it's too high.
maybe this can help http://forum.xda-developers.com/showthread.php?t=1644345

I used to use rootdim on my thrive to get it so low I could use the tab as an alarm clock with the screen on and facing me all night.
But trying the same on this a510, the backlight just goes completely off if I try to set it any lower than default. So I wonder if it is a hardware limitation.
It would be nice though. This thing makes my eyes hurt in the morning on the bus to work.

Overclock possible please? Thanks.

I'm currently quote happy with the stock ROM apart from the lack of CIFS so I took the modules from /system/lib/modules [NoThrills A510 WorldWide optimized Stock ROM] and copied them to my stock (but rooted) A510.
CIFS works perfectly!
Thanks!:good:

Feedback:
I've tried Smartass v2 and Lulzactive and they seem to eat up more juice.
I then checked System Tuner Pro for my CPU times, and I noticed that my CPU would only go from inactive to 1.3 or 1.4GHz. It doesn't use the values in between.
I then switched to Interactive, and I can see the CPU clocks like 400+ and 600+ used again.
Not sure if it's just me though, but I'm putting it out there for everyone to test. Nevertheless, I love this kernel, I love the optimized A510 that you released as it fixed my screen responsiveness issue entirely. Take that Acer!

Another question, what's the best app to tweak the CPU governor? Or I guess... what do you use NoThrills?

I'd say NoFrills CPU Control- works fine on ICS/JB
Other one is SetCPU but last time I used it there were problems on ICS (January/February)

I've used SetCPU without problems myself. I do however have the purchased version, which is different from the free version that can be found on XDA. That one doesn't seem to be updated anymore.

I've posted about my touchscreen problems in some games in the Optimized ROM thread.. but no answers there. The problem is only there when I use the NoThrills kernel... the stock kernel works good. Have you got any idea what the problem can be?

I had the same problem with some games too ... so I came back to stock kernel
another bug I noticed: battery can't charge to 100%, always blocking at 99%

I just charged to 100% yesterday, it worked.
Did you try to restart your tablet, then charge again?

I didn't reboot just after being blocked at 99%
but between 2 charges I rebooted it and in both case blocking at 99
I came back to stock kernel so I can't test it again

Aaargh, I hate all this touch problems with this f#@$ tablet. Games only playable with the stock kernel, but a piano app is not usable because it doesn't always detect your fingers. Sometimes it's perfect, you can press up to 10 keys at the same time, and sometimes it doesn't recognize two fingers. So I probably need the custom kernel for this.. but I don't want to flash a different kernel for different apps.
This is really the worst device I've ever bought, I hate this piece of crap. I hope this annoying problem will be solved in some future kernels but untill now there isn't a perfect one out there which solves all the problems. No offence to anyone, I know it's all in your spare time, but it's a rant to Acer. A device of about €450 which is soo bad, that's some really bad engineering!

Maybe this new file format would be considerated (or not ) ?
