It's probably not so much the moptherboard as the new RAM sticks on the market. I've noticed 1, 2, 4...GB sticks over at pricewatch... I beleive when they advertised my 3 slot dual 370 board as capacitating up to 1.5 GBs of RAM they were refering to 3 of the the largest(512MB) boards(At that time. I also askeds a question here once..about adding new sdram dimms to my old old mother board, and sombody called my a monkey, then asled if a round peg would fit into a square hole... = )
