hi, this is my first time posting. i've been doing some research on what is the best way to install ram but i can't find a good answer. i currently have two sticks of 512mb ddr400 ram. the question is: am i better off running in dual channel mode where i effectively have 512mb of ddr800 ram or running them at single channel mode and have effectively 1gig of ddr400 ram. oh, i am running a MSI K7N2 ILSR mobo with an xp2500 cpu running at xp2800 speeds. i know the perfomance boost for dual channel is about 5% but what is the performance boost of going from 512mb of ram to 1gig of ram. finally i use my computer mainly to play games and to rip and encode dvds. thanks.
