I hope you have solved this problem, but i hate to inform you that windows 95 98 and me does not support ram over 768mb, if you try and run it with 1024 your computer will say not enough memory, but if you run a 512 and a 256 thats the best you can get out off the above os, switch to xp and you can have your 1024, but even if a board says you can have 2gb you can not that equals 2048gbs which again is to much for the board to handle.
