The
•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 2 and Table 1 show several possible memory configurations.

Table 1
*SDRAM only supports 32, 64, 128, 256MB DIMM modules.
*We recommend to use PC100 Memory Module for bus speed 100MHz and PC133 Memory for bus speed over 100MHz.
