If the system BIOS can not detect the SPD on the DIMM module. the system
BIOS will use the default parameters which is saved in the BIOS for the memory
subsystem. Such parameter will work with most DRAM modules, but it will
reduce the system performance because it is not optimized.
According to what Intel suggested, the system board shall stop and not to
continue when no SPD module can not be detected. However, this mainboard is
downgrade compatible with the 66HMz Pentium
TM
II processors. In order to
make sure that the system board will work normally with 66MHz Pentium
TM
II
processors, the system BIOS will continue to load the operation system when it
can not detect the SPD RAM module. Nevertheless, SRAM module with SPD
feature is still strongly recommended when you are using the 100MHz Pentium
II
TM
processor.

In order to increase of the system performance, two suggestions are recommended
when you are installing the DIMM modules :
