I would like to add more RAM to my laptop which is running Vista Home Premium ... presently I have 2 gigs of ram ... the laptop is running great, I have no problems but I would like to upgrade it .... the laptop supports dual channel ...

here are the specs on my laptop

I've noticed alot of laptops that are out now are running with 3 gigs of ram ... and I know that vista 32 bit won't recognize 4 gigs of ram ... what are the benefits of running dual channel ... am I better off to purchase 2 - 2 gigs strips of ram and run with a total of 4 gigs, or can I just add one 2 gig strip of ram and run with a total of 3 gigs ...

will there be a drop in performance if the laptop isn't running dual channel ...

thanks for your help ...
