3-2 Main Memory
ROBO-679 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-679 will automatically detect
memory clock, based on the processor and SDRAM used. Please refer to the
following table for details.

For system compatibility and stability, don’t use memory module without brand.
You can also use the single or double-sided DIMM with ECC feature
(2)
.
Randomly installing DIMM in any one of the DIMM sockets is allowed. You can
install different size of DRAM module on DIMM1, DIMM2 or all to make the
system boot.
Watch out the contact and lock integrity of memory module with socket, it will
impact on the system reliability. Follow normal procedures to install your
DRAM module into memory socket. Before locking, make sure that all modules
have been fully inserted into the card slots.
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.
(2)
Due to Intel 82815 Chipset limitation, the type of SDRAM with ECC
function is not supported. In the event of ECC SDRAM being adopted,
ECC function is NOT supported while ECC SDRAM can act only as a
normal SDRAM without causing any error.
(3)
Due to Intel 82815 chipset limitation, Buffered (Registered) SDRAM is
not supported. Buffered SDRAM will simply freeze up the system.
