[QUOTE="D3v1L80Y, post: 537806, member: 2960"] RAM does NOT "speed up" your computer. I'll state that again..... [B][U]RAM does NOT "speed up" your computer.[/U][/B] Up to a point, adding more RAM can cause your computer to [I][B]seem[/B][/I] faster on [U]certain types of operations.[/U] This is because adding RAM lessens the use of the Virtual Memory Manager's swap file. It doesn't magically make your processor or hard disk any faster. If you don't have enough RAM, then your VMM swaps data to the virtual RAM on your hard disk. Swapping data to the hard disk takes longer than if it were simply stored in actual (not virtual) RAM. More actual RAM can mean less swapping to the hard disk, which means that some applications and programs that require it will run smoother. There is where you have your "perceived" speed increase. Also, if you had 2GB of RAM in your computer, and you didn't use applications that required all of it, the VMM would have plenty of room and you would never see it swapping anything. If you then added more RAM after that, it would have no effect. [/QUOTE]
