3.3 System Memory Configuration
The AB49/AB49N mainboard has two 184-pin DIMM banks that allow you
to install from 128MB up to 2GB of system memory. Each 184-pin DIMM
(Dual In-line Memory Module) bank can accommodate 128MB, 256MB,
512MB, and 1GB of PC1600/PC2100/PC2700 compliant 2.5V single or
double side DDR SDRAM modules. DIMM slots are arranged in two banks,
each memory bank made of one bank and providing a 64-bit wide data path.
1. Install Memory:
Install memory in any or all of the banks. The combination shown as follows.
Note: The total installed memory does not exceed 2GB.
Note: 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.
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.
