System Memory Configuration
Memory Layout
The BXB supports (4) 168-pin DIMMs (Dual In-line Memory Module). The
DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized
DRAM). Do not mix EDO DIMM and SDRAM DIMM in the system.
•
SDRAM DIMM may be 100 MHz (10ns) or 125 MHz (8ns) bus speed.
•
SDRAM DIMM may be 8MB, 16MB, 32MB, 64MB, 128MB, or 256MB
registered (see table 2).
•
100MHz FSB frequency requires PC100 compliant SDRAM memory.
•
4 clock SDRAM is recommended instead of 2 clock.
•
If using 50ns and 60ns EDO DIMM together you must set BIOS for 60ns.
•
Table 1 shows several possible memory configurations.
•
Table 2 shows compatible SDRAM components types according to Intel
440BX datasheets. (Internet: http://developer.intel.com)
