System Memory Configuration

Memory Layout

The EP-3VCA2 supports (3) PC133 168-pin DIMMs (Dual In-line Memory Module). The DIMMs is 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 using both SIMM and DIMM.

DIMM 1	Bank 0/1		-Synchronous
DIMM 2	Bank	2/3
DIMM 3	Bank	4/5

Table 1

*SDRAM only supports 8, 16, 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.
