TheCB650M-BX motherboard uses only DIMMs. Two sockets are available for
3.3V unbuffered SDRAM for up to 256MB of SDRAM.
1. General DIMM Notes
■For the Host bus to operate at above 100MHz, use only PC100-compliant
DIMMs. The CB650M-BX motherboard operates at 100MHz, thus most
systems will not even boot if non-compliant modules are used because of
the strict timing issues involved under this speed. If your DIMMs are not
PC100-compliant, set the Host bus frequency to 66MHz for the system
stability.
■Single-side and double-side memory modules are supported.
■BIOS shows SDRAM memory and using banks on bootup screen.
2. Memory Configuration
DIMM memory configuration is auto-banking and therefore does not need to
be installed in any particular order. The following table lists a number of
possible memory configurations.
