System Memory Configuration
Memory Layout
The EP-3VCA supports (3) PC133 168-pin DIMMs (Dual In-line Memory
Module). The DIMMs is only for SDRAM (Synchronized DRAM).
 DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or
125MHz (8ns) bus speed.
 If you use both 50ns and 60ns memory you must configure
your BIOS to read 60ns.
 When using Synchronous DRAM we recommend using the
4 clock variety over the 2 clock.
Figure 6 and Table 1 show several possible memory configurations for using SDRAM.
* SDRAM only supports 32, 64, 128, 256MB DIMM modules.
* We recommend to use PC100 Memory Module for bus speed between 66MHz
and 100MHz and PC133 Memory for bus speed over 100MHz.
* Using non-compliant memory with higher bus speed (over clocking) may
severely compromise the integrity of the system.
