Recommended Virtual Memory

Just let Windows manage it for you but if you want to set it no big deal. It's good to split it between the drives, put it on a non-OS drive, put it on the fastest drive, or put it on a flash drive. I'm not sure which is best however. As for the size, the combined size is what counts, I'd suggest whatever Windows recommends.

Keeping all your programs off the OS drive may help slightly but it's not a big deal. They can load from C: or D: just the same and its running programs that slow your system down. Having a ton of programs installed, no matter where, won't slow down your system if they're not running.

Swap file on a separate disk is good for a bit of a speed boost (drive does not have to seek to the swap file and back to the applications), min max set to the same size would prevent fragmentation of the swap file. Keeping the swap file at 1.5 gig should be good. You don't need to have a swap file on both drives, that's actually not a good idea.

"I've read an article that it should be set like RAM size x 1.5, that would give me 3072 since I have 2gb of RAM, would that mean I should enter 3072 for initial and maximum size for BOTH drives (c: and d: )? "

**I already did this, I put in 3072 for Initial and Maximum Size for both c: and d: **

@hang-the-9, so you mean what I did was actually called "swap file"?

@all, mayankleoboy1, I also prefer to set it up my own. Should I be entering 3072 for Initial and Maximum Size for both c: and D: given that my RAM is 2gb?

Because I've watched this increase in Virtual memory thing on youtube and accordingly it's advisable only for those who only got less than 4gb or RAM and so I followed he's simple tutorial. But, he only got 1 drive (c: ) and I got 2 (c: and d: )... that's where I need some help, of what value I should enter on both.

The Swap File or Page File for Windows is basically extra memory space that is put on the hard drive for programs to use.

Unless you are copying or cutting gigabytes into memory (ie, playing with video editing, photo editing or music editing) you don't need it.

Having a large Paging File actually slows your computer down. Unless you have your Page file on a SSD Hard Drive.

edit:

Virtual Memory = Swap File = Page File

Here's an excellent article The How-To Geek wrote on Lifehacker about this controversial topic.
