System Memory Configuration
Memory Layout
The EP-3WXA/4/4Y supports (2) 168-pin DIMMs (Dual In-line Memory
Module). The DIMMs can be either EDO (Extended Data Out) or SDRAM
(Synchronized DRAM).
• 100MHz system memory bus frequency. Even if the system host bus is
66MHz.
• 8MB to 256MB using 16MB/64MB technology (512MB using 128MB
technology).
• 256MB Support Registered synchronous DRAM Memory Modules.
• We recommend to installed the “PC/100MHz SDRAM Spec.”, using
DIMM SDRAM must be 125MHz (-8ns) bus speed. If used 100MHz
(-10ns) SDRAM may be critical timing for the motherboard.
• DIMM SDRAM may be 100MHz (-10ns) or 125MHz (-8ns) bus speed.
Figure 2 and Table 1 show several possible memory configurations using
* SDRAM only supports 16, 32, 64, 128, 256MB DIMM modules.
