Memory
The SBP-205 provides two 168-pin DIMM sockets. The board supports up to
512MB of RAM with each socket supporting DIMMs up to 256 MB.
Memory Guidelines
The SBP-205 comes with 128 MB SDRAM installed in one DIMM socket. When
selecting additional memory, use the following guidelines.
The SBP-205 supports either FSB ECC or non-ECC SDRAM PC-133.
SDRAM PC-133 can be installed in one or both DIMM sockets.
Minimum memory size is 64MB; maximum total memory size is
512MB. Memory size and speed can vary between sockets.
Select 168-pin DIMM sizes as detailed in the following chart:

SPD Data Structure
To be fully compliant with all applicable Intel
®
SDRAM memory specifications,
populate the SBP-205 with DIMMs that support the Serial Presence Detect (SPD)
data structure.
If the installed memory modules do not support SPD, you will see a notification to
this effect on the screen at power up. The BIOS will attempt to configure the
memory controller for normal operation
.
