1. Install Memory:
Install memory in any or all of the banks. The combination shown as follows.
Note: For AN35 Ultra/AN35N Ultra, installing a DIMM in any
single slot leads to a 64-bit data transfer rate. To activize
the dual-channel feature of a 128-bit data transfer rate, install
DIMMs in any of the following sequences:
ØDIMMs 1 & 3,
ØDIMMs 2 & 3, or
ØDIMMs 1 & 2 & 3.
(AN35-400/AN35N-400 does not support the dual-channel mode.)
2. Upgrade Memory:
You can easily upgrade the system memory by inserting additional DDR
SDRAM modules in available DIMM banks. The total system memory is
calculated by simply adding up the memory in all DIMM banks. After upgrade,
the new system memory value will automatically be computed and
displayed in the field "Standard CMOS Setup" of BIOS setup program.
