My question is that if accumulating virtual memory have any effect. What I mean is that, say I have 3GB or RAM and I used 1 GB on a game.(For this I will use. Minecraft.) I currently added 4 GB of virtual memory, I have 3 GB total, and I have 1 GB currently processed in my Minecraft. So would I actually have 7 GB of RAM, and could accumulate more than what I originally could before, in the same time getting more FPS, quality, and a overall better experience?
Sorry if this is confusing. :/
What's confusing is your use of the term virtual memory. Virtual memory is an extension of real memory that's kept on your hard drive. If you need to use it, then blocks you need are swapped from your real physical ram. This process of swapping can kill performance. So using virtual memory works well if you have stuff kept inactive in the background or your program works on blocks of memory where swap doesn't hurt much.
It is Not real RAM
it is just a swap space.
Using the swap file otherwise known as virtual ram,
will actually slow down the computer.
it also causes excessive hard drive wear.
turn off the virtual ram,
then windows and programs are forced to run in the RAM
thus slightly speeding up the computer.
Virtual memory is swap space on your harddrive. Theoretically, you don't use it until you run out of RAM, so it's not "extra" as in being additional to your system memory. If you have a HDD rather than SDD, using swap space significantly slows down your computer. Indeed, in special cases we might even disable virtual memory all together so that a system runs smoother, rather than slowing down whenever Windows *thinks* it should be swapping (paging). To clarify, the disk space is used as RAM, but in a HDD access is hundreds of times slower. That's not good.
The long and short of it is that your computer is only supposed to do swapping when it can't keep up with everything it's been tasked with. Swapping is generally a bad thing. Now it's not completely bad, because at that point it would start spewing errors all over the place if it didn't have this so-called "virtual memory" to pick up the slack.
In general, you only want to increase your virtual memory if you have an application saying it needs more.
P.S. I didn't even realize it, but I do have my virtual memory set to zero right now in Windows 7. I had completely forgotten about that, it's been like that about 4 months. I don't recommend this, as some application do demand they have some swap space. But I'm a gamer, btw.
