My Asus E1972 manual says it supports up to 2GB. I have 4 x 512MB DIMM and I can't get it to recognize more than 1GB of memory. I have installed them all individually so I know all the DIMM are good.
With all the DIMMs plugged in I get this message on boot.
"Due to chipset limitations this motherboard supports a maximum of 2GB and 4 ranks of memory."
But thats exactly what I have plugged into it!!??
