I was told that windows ME had restrictions on it's memory, my problem is I have just upgraded my machine to a P4 3.0g (800fsb) and thought I would go the whole hog and fitted 1.0 gig DDR 400 I will have to wait for spare cash to upgrade to win XP which can address it.
If I try to run some of the freebies that came with the Asus geforce 5700 8*AGP card the system locks up! with a white screen, take out one of the memory modules and whalla it all works perfectly. the only thing then is the memory only runs on single channel. I was informed it's something to do with the AGP graphics card and Windows fighting for addresses.
