Warning: The default memory timing setting is 60ns to
obtain the optimal performance. Because of the
specification limitation, 70ns SIMM is recommended to
be used only for CPU external clock 60MHz.
Tip: EDO DRAM is designed to improve the DRAM read
performance. Unlike traditional fast page mode, that tri-
states the memory output data to start the precharge
activity, EDO DRAM holds the memory data valid until
the next memory access cycle, which is similar to pipe-
line effect and reduces one clock state.
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. But because of chipset limitation,
the maximum is only 128MB.
