turn on and POST (power on self test)

SDRAM memory modules are supported

Valid DIMM Configurations
The processor supports 64-bit mode and 128-bit mode configurations of the DIMMs. In 64-bit
mode, only DIMMs 1 and 3 can be populated. Possible combinations of DIMMs in 64-bit mode are
listed in the table as below. In 128-bit mode, a minimum of two DIMMs is required to create the
128-bit bus; therefore, DIMMs can only be populated in even numbered pairs in slots 1 & 2, and 3
& 4. The following table shows some possible combinations of DIMMs for 128-bit mode. Not all
possible combinations are listed in the table.
TM
processors support 64bit (non-interleaved) or 128bit (interleaved)
