Vigilante said:meNOname, I think you may be thinking of RAM "speeds" versus RAM "size". Where if you put, say, a PC2700 and a PC2100 together, it will run at the lower speed of the two, if it even runs at all.
But maybe this changed with Dual Channel.
does it have anything to do with the memory size? like if you have a 256 and a 512 stick, the computer will only use the lowest stick?
