What benefits would you gain from going up to 16GB?
I'm actually at 12 now(I took an 8gb stick out of my old computer and put it into this one) so would buying another 8gb stick for another 4gb give that much of a difference?
I'm kind of computer illiterate on most things so forgive me =x
Ram works best when it's matched in sets - especially from the same RAM types.
8 + 8
Then there is also the numbers on the RAM types.
For example: Ram that is labelled 1333 is best matched with other Ram labelled 1333.
*Higher the numbers the better the RAM, but that Crucial link I gave you will give you the RAM numbers and type that are best for your computer. You don't want to choose RAM that's too high in numbers and not compatible with your system because it may or may not function and either way it won't function optimally. That Crucial scanner will give you the RAM that's designed for optimal performance with your system.What will the direct impact be on your computer?
Primarily you will notice slight increases of roughly between 5-10% improvement in load speeds. ((RAM acts like your real life office desk where it pulls things from the filing cabinet(your hard drive) and lays out all the papers you need to keep them close at hand. The more organized it is(optimal RAM type) the faster you are able to get your work done.))
*Note: It's only a minor improvement but it's one of the most efficient and cheapest ways to upgrade a computer.
