ROBO-678 provides two DIMMs (168-pin Dual In-line Memory Module) to
support 3.3V SDRAM (Synchronized DRAM) as on-board main memory. The
maximum memory size is 512MB. ROBO-678 will automatically detect
memory clock, based on the processor and SDRAM used. Please refer to the
following table as your reference.

For system compatibility and stability, don’t use memory module without brand.
You can also use the single or double-side DIMM with ECC feature
(2)
.
Randomly installing DIMM in any DIMM socket is allowed. You can install
different size of DRAM module on DIMM1, DIMM2 or all to boot up system.
Watch out the contact and lock integrity of memory module with socket, it will
impact on the system reliability. Follow normal procedure to install your DRAM
module into memory socket. Before locking, make sure that the module has
been fully inserted into the card slot.
NOTE :
(1) To maintain system stability, don’t change any of DRAM parameters in
BIOS setup to upgrade your system performance without acquiring
technical information.
Due to Intel 82815 chipset limitation, SDRAM with ECC function is not
supported. In the event of ECC SDRAM being adopted, ECC function is
NOT supported while it is still OK to use this type of SDRAM.
Due to Intel 82815 chipset limitation, Buffered (Registered) SDRAM is
not supported. Buffered SDRAM will simply freeze up system.
