ok, i got a new motherboard. in the manual, it says it takes the following type of RAM: "3 x 184-pin DDR DIMM sockets for up to 3GB unbuffered ECC and non-ECC PC3200/PC2700/PC2100/PC1600 SDRAM memory" My other motherboard used PC100 RAM. Can I put some of that in this new motherboard? i've never heard of PC1600 RAM. might that be the PC100?
