I basically have 2 options (it doesn't really matter why). I can have 2GB of RAM installed using the dual channel option, or use 3GB with single channel. I have an AMD 64 X2 3800 processor, and currently using windows 7. and I want to know which of these 2 scenarios is "better"? I use my PC for what most people use it (internet, word, etc), but I ocassionally play games, edit videos, etc.

Ideally, 3GB in dual channel mode would be the way to go, but I think 3GB in single would trump 2GB in dual. Just make sure it's the right RAM...depending on your system, either DDR400 or DDR2-800.

I have the right RAM, I even have the 3GB already installed in single channel. Sorry for my english but I couldn't understand this phrase "but I think 3GB in single would trump 2GB in dual". What do you mean by that? that is better to have the 3GB?

Yes, trump means it's better. It a phrase from a game of cards. We Americans sometimes use phrases that only people in this country are familiar with and sometimes they don't get it. But, yes Jam thinks that would be better.

Hi be specific how many ram modules you have 3 GB single module? 2 GB single module?if you have both use them both it will be working in single channel but if you are working in xp 32 bit it will utilise only up to 4 GB [as per limitations] for using duel channel buy duel channel memory kit as they are made for that specification.mixing diff ram modules wont work for duel channel mode

He surely has 3 1Gb modules. Best would be 2 1Gb modules and 2 512Mb modules so dual channel would work. Whether 32bit or 64bit flavor of Windows 7 the best choice is still 3Gb in single channel vs. 2Gb in dual channel. Skip
