System Memory Configuration
Memory Layout
The board supports (2) PC100 168-pin DIMMs (Dual In-line Memory Module).
The DIMMs is for SDRAM (Synchronous DRAM) .
DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns),
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 configuration.
* SDRAM supports 32, 64, 128, 256MB DIMM modules.
* We recommend to use PC100 Memory Module for bus speed between
66MHz and 100MHz.
* Using non-compliant memory with higher bus speed (over clocking) may
severely compromise the integrity of the system.
