There is no jumper setting required for the memory size or type. It is
automatically detected by the system BIOS. You can use any single side SIMM
and DIMM combination list below for BANK0/BANK1 or DIMM socket, and the
total memory size is to add them together. Note that because TX chipset
limitation, the maximum is only 256MB.

For double side memory module, there is one limitation. This mainboard supports
only 4 RAS# (Row address latch) signals for DRAM control. They can only be
occupied by one DRAM module, they can not be shared. The simple rule is: If
double side module at either Bank0 or DIMM1, the other must be empty. If
you use at DIMM1, Bank0 must be empty. Bank1 and DIMM2 have the same
limitation.
