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. Note that because chipset limitation, the
maximum is only 256MB.
