System Memory Configuration
Memory Layout
The EP-6ZXM supports (3) 168-pin DIMMs (Dual In-line Memory Module).
The DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized
DRAM).
• We recommend not mixing SDRAM DIMM and EDO DIMM
together.
• EDO DIMM can only be used with the 66MHz FSB.
• We recommend using at least 125MHz (-8ns) SDRAM DIMM at the
100MHz (or higher) FSB as timing becomes more critical at these
higher speeds.
• DIMM SDRAM may be 83MHz (-12ns), 100MHz (-10ns) or 125MHz
(-8ns) bus speed.
Figure 2 and Table 1 show several possible memory configurations using
DIMM 1 (M1)
DIMM 2 (M2) (Dual or Single Bank)
DIMM 3 (M3) (Single Bank Only)
