System Memory Configuration
Memory Layout
The board supports (3) PC1600/2100 184-pin DIMMs (Dual In-line Memory Module).
The DIMMs is for DDR SDRAM (Double-Data-Rate Synchronous DRAM) only.
Figure 6 and Table 1 show several possible memory configurations.
* DDR SDRAM supports 64, 128, 256, 512MB DIMM modules.
* We recommend to use PC1600 Memory Module only for front-side bus 100MHz.
* Can not mixing the unbuffered and registered DDR SDRAM on DIMM1,
DIMM2 and DIMM3 socket.
* Supports PC1600 modules with 2-2-2 timing.
* Supports PC2100 modules with 2-2-2 timing.
