Use Hard Disk As RAM

Use Hard Disk As RAM

Hi Friends!

We all face performance issues in our system(general sense!) like the computer is slow... Why does system becomes slow? From where (memory) does CPU takes data to execute (forget about cache right now)? What is RAM?

Now let's get an idea about what RAM is:

RAM is Random Access Memory( i.e memory reads can be Random) , is faster (approx. 10 times faster than Secondary storage) and all the programs to be executed are brought into RAM and then fed to CPU.

So the focus of this blog will be to use spaces in our Hard disk as if it were RAM (a concept called as Paging in OS). So let's get started

Step 1: Go to Start-> Computer(right click)-> Properties

Step 2: Now on the left pane, under Control Panel Home, click on Advanced system settings

Step 3: Navigate to Advanced tab, under Performance tab, click on Settings... 

Step 4: When Performance Options window, click on Advanced tab.

Step 5: Under Virtual memory, you get to change the paging file size for all drives. Click on Change... button (step 3-5 are shown below)

Step 6: Here you can uncheck Automatically manage paging file size for all drives and set values as per your requirements

Click OK. It will ask you for a restart. Restart your system and we are done!
