2Gb or 3Gb Ram?

Hello...
Can I put a 1gb Ram and 2gb ram in a system?

It is possible, but it isn't recommended that you are mixing sticks

You will have to figure out if the extra memory will outweigh them running in single channel mode. I don't think one or the other will matter.

Also I have only two slots of ram in my mainboard.
(it's Asrock G41 with onboard 512mb vga)
