I know this is really elementary but this is my first time to build a system and am curious and have found nothing about it yet. OK....I am getting 512MB of DDR RAM...most likely Crucial....I will have an Asus MoBo (P4B266 or P4S333) does it really matter if I get 1 stick of 512 or 2 of 256? Any dif. at all? Please let me know. Thanks
