3.3 System Memory Configuration
The AN35 Ultra/AN35N Ultra/AN35-400/AN35N-400 mainboard has three
184-pin DIMM slots that allow you to install from 128MB up to 3GB of
system memory. Each 184-pin DIMM (Dual In-line Memory Module) slot can
accommdate 128MB, 256MB, 512MB, and 1GB compliant 2.5V single or
double side 64-bit wide data path DDR SDRAM modules. You do not need
to set any jumper to configure memory since the BIOS utility can detect the
system memory automatically. You can check the total system memory value
in the BIOS Standard CMOS Setup menu. Note: The total installed
memory does not exceed 3GB.
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, in-
stall DIMMs in any of the following sequences:
Ø
DIMMs 1 & 3,
Ø
DIMMs 2 & 3, or
Ø
DIMMs 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 up-
grade, the new system memory value will automatically be computed and
displayed in the field "Standard CMOS Setup" of BIOS setup program.
