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.
