RoehSoft Ram Expander. Use your sd card as ram memory.

Roehsoft Ram Expander.

When your phone is cursed with little amount of ram memory, and you need to perform some minor multitask or play your fav HD game, but shows up "out of memory message, " ?? Well, rohesoft ram expander is here just for you. If your phone supports external sdcard, you can use your sdcard as ram memory. You will never have the out of memory message again or lags when you play some HD games on your device or automatic termination of background app.

Yes, thats right, you can use your sdcard space as ram. This application will not add extra ram as it is a hardware but this will create a partition on you sdcard for swapping ram memory. When you go to the settings and check your ram memory, it will still be the same. What this application does is that it will reserve the amount of space that you want to use as ram in you sdcard and use that available space as ram memory. This application can create up to 4gb of  virtual ram memory. You can also change the dependency of the phone/ kernal and choose which ram to use most, either the inbuilt ram or the virtual ram created using the app or both for 50-50 %.

So, lets get started.

Roehsoft Ram Expander is a paid app and you can download it from the play store. This app requires root access to run. So better have your phone rooted if its not. You may need to check if your device is compatible or not but this app is meant to work on old devices running on android 1.6 and up. Which means you can use this app on some old phones too. And a class 10 Sdcard is prefered. If you have other class sdcard, this app may take lots of time to create the partition. You can always give a try though.

Download it from here

Install the app and open it.

For those who are running on cm 12.1 on s-advance, toggle the root access menu from the developers option once. Change the settings from "apps only" to "app and adb". And for other device, you can use SuperSu and grant the root access.

The app will check for valid license after installing and opening for the first time. So, your phone must be connected to the internet.

 Press the three dot menu and first select SWAPDIR option and then select the external sdcard for creating the virtual ram. I suggest you select the third path for creating swap file. That is gonna be like " Swapfile - /mnt/media_rw/sdcard1 ."
This way you will find the created swap file easily by just browsing over to your external sdcard.

Class 10 sd card is recommended for this task. Other class sdcard works too but as i've told before, it will take lots of time to create swap file. And also remember, perform the steps one by one in order. App may not work correctly if you skip the steps or forget to select the path for creating swap.

Read the notice that pops up and press ok. The app will start as in the screenshot below. Follow the Steps one by one:

• First Uncheck the Notify Icon button if you donot want to keep a notification icon on the status bar and notification drawer. If active, it is helpful for you to know that Swap/ Virtual ram is active and running. You may not want to keep this seeing in the future. So i recommend it off.
• Click on PerfectKernal and Activate it, if your device have a kernal that works well with Roehsoft Ram expander, it will activate
• Now the main part " SwpFile". Select the amount of space to use as Virtual Ram. Slide to the right to increase or slide to the left to decrease. You can use all 4Gb if you have enough space on your sdcard. I don't use the whole cause i know my phone will never need that amount or ram memory. So, im keeping it simple as in the screenshot above.
• "Swappiness" means on which memory the phone should rely on. Either the created virtual ram, or the actual phone ram. I chose the virtual ram for testing setting it on 95. And its works very effectively. You can choose for a 50-50.
• Set MinFreeKB ranging from 5 to 50mb and leave out all the rest.
• When everything is set, press the big SWAP ACTIVE button. It will start to create the partition. You will have to wait according to the size you choose for virtual ram

After the process completes, you will have something like this on your screen:

Click on Autorun for virtual ram to run after reboot. Then you can close the app. You will not need to run this app again if everything goes fine.

Now the thing is, how do we know if the phone is using virtual ram or not. You will need to reboot the phone once everything is done. So, reboot. After that, to check if the Swap is working or not, you will need to install an app called Terminal Emulator. Its free and you can download the app from playstore easily.

Install terminal emulator and open it.

Type " free " and hit enter.

You will see:

 Check the Swap value. If its zero like in the above screenshot, then your swap/ virtual ram is not working. You will then need to first uninstall the Roehsoft Ram Expander app and delete the Swap file created on your sdcard. You can find a file named " swapfile.swp " on your sdcard and can manually delete it but only after uninstalling the app first. Then a reboot will turn things back to normal and you can start the process again.

If you have some values on Swap like in the screenshot below, then your virtual ram is working. You can see my swap value 2408444 total and free.

0 in used means no apps are reliying on the virtual ram. Itll will raise after you start apps on the phone.
Thats it.
Enjoy your old phone with lots of memory.
